  1. Intravesical catheter knotting: an unusual complication of suprapubic catheterization. (United States)

    Yiğiter, Murat; Salman, Ahmet Bedii


    Suprapubic catheterization is commonly used to drain urine temporarily from the bladder. Although it is a commonly performed procedure, it is not without complications. Many of these complications related to surgical technique. However, some unpredictable complications are related to the catheter itself. Intravesical catheter knotting is a very rare event and usually has been reported in feeding catheters used as an urethral catheter. We report a case of a suprapubic Cystofix catheter knot, removed by sustained traction. This complication was probably due to an excessive length of catheter having been inserted into the bladder, thus forming redundant loops that increased the risk of bending onto itself.

    Healy, Eibhlín F


    Suprapubic catheterization is commonly used for postoperative bladder drainage after gynecologic procedures. However, recent studies have suggested an increased rate of complications compared with urethral catheterization. We undertook a systematic review and meta-analysis of randomized controlled trials comparing suprapubic catheterization and urethral catheterization in gynecologic populations.

    Han, Christopher S; Kim, Sinae; Radadia, Kushan D; Zhao, Philip T; Elsamra, Sammy E; Olweny, Ephrem O; Weiss, Robert E


    We performed a network meta-analysis of available randomized, controlled trials to elucidate the risks of urinary tract infection associated with transurethral catheterization, suprapubic tubes and intermittent catheterization in the postoperative setting. PubMed®, EMBASE® and Google Scholar™ searches were performed for eligible randomized, controlled trials from January 1980 to July 2015 that included patients who underwent transurethral catheterization, suprapubic tube placement or intermittent catheterization at the time of surgery and catheterization lasting up to postoperative day 30. The primary outcome of comparison was the urinary tract infection rate via a network meta-analysis with random effects model using the netmeta package in R 3.2 ( Included in analysis were 14 randomized, controlled trials in a total of 1,391 patients. Intermittent catheterization and suprapubic tubes showed no evidence of decreased urinary tract infection rates compared to transurethral catheterization. Suprapubic tubes and intermittent catheterization had comparable urinary tract infection rates (OR 0.903, 95% CI 0.479-2.555). On subgroup analysis of 10 randomized, controlled trials with available mean catheterization duration data in a total of 928 patients intermittent catheterization and suprapubic tube were associated with significantly decreased risk of urinary tract infection compared to transurethral catheterization when catheterization duration was greater than 5 days (OR 0.173, 95% CI 0.073-0.412 and OR 0.142, 95% CI 0.073-0.276, respectively). Transurethral catheterization is not associated with an increased urinary tract infection risk compared to suprapubic tubes and intermittent catheterization if catheterization duration is 5 days or less. However, a suprapubic tube or intermittent catheterization is associated with a lower rate of urinary tract infection if longer term catheterization is expected in the postoperative period.

  4. To clamp or not to clamp? Bladder management by suprapubic catheterization in patients with neurogenic bladder dysfunction. (United States)

    Pannek, Jürgen; Göcking, Konrad; Bersch, Ulf


    In a small subset of patients with neurogenic lower urinary tract dysfunction, insertion of suprapubic catheters (SPC) cannot be avoided. If SPC has to be utilized, catheter clamping and anticholinergic medication are often recommended, but evidence supporting this view is scarce. We determined the influence of anticholinergic medication and catheter clamping on urodynamic parameters and the status of the urinary tract in patients with chronic suprapubic catheterization. In a retrospective study, the results of urodynamic testing, sonographic evaluations, and urinalyses of 85 patients with chronic (>1 year) suprapubic catheterization due to neurogenic bladder dysfunction were analyzed. The 51 male and 34 female patients (mean age 55 years) were managed with an SPC for 65.3 ± 48.0 months. Forty patients had an SPC for more than 60 months. Comparing the results before SPC insertion with the last follow-up examination, no significant differences in detrusor compliance and maximum detrusor pressure were detected, whereas bladder capacity significantly decreased. In three patients, alterations of the upper urinary tract were found. The results were not significantly different between the patients using anticholinergic medication and/or catheter clamping and those who did not. According to our study, routine use of anticholinergic medication and clamping of catheter does not seem to be necessary to preserve detrusor compliance and renal function in patients with SPC and neurogenic bladder dysfunction.

    Kozer, Eran; Rosenbloom, Ehud; Goldman, Dorit; Lavy, Gila; Rosenfeld, Noa; Goldman, Michael


    Proper diagnosis of urinary tract infections depends on obtaining an uncontaminated urine sample for culture. Suprapubic aspiration and transurethral catheterization are the 2 recommended procedures for obtaining specimens for urine culture from young infants. The objective of the current study was to compare the pain that is experienced during these 2 procedures when performed in young infants. A prospective, single-blind, randomized, controlled study was conducted at a university-affiliated hospital in Israel. Institutional Research Ethics Board approved the study. Infants who were 0 to 2 months of age and presented to the emergency department with fever and therefore required urine collection for culture were randomly assigned evenly into 2 sample collection groups: suprapubic aspiration or transurethral catheterization. Patients were excluded when they were born prematurely or had had a previous sepsis workup or other painful procedures or an anomaly of the urogenital system or abdominal wall. Eutectic mixture of local anesthetic cream that contained lidocaine and prilocaine was applied 1 hour before the procedure. The urethra was catheterized using a 5-Fr latex-free feeding tube that was lubricated with sterile water-soluble jelly that contained 2% lidocaine hydrochloride. Pediatric residents who were experienced with the procedures performed both suprapubic aspiration and transurethral catheterization. The parents were instructed to use any comfort strategies that they wished, including verbal or physical comforting and pacifiers. Pain during collection was assessed on a 100-mm visual analog scale by a nurse and a parent. In addition, the infant's upper part of the body was videotaped during the procedure. An investigator, who was blinded to the procedure, assigned a point score according to the Douleur Aigue du Nouveaune neonatal acute pain scale. For ensuring a successful blinding process, the following steps were taken. First, camera recording started 30

  6. Preventable long-term complications of suprapubic cystostomy after spinal cord injury: Root cause analysis in a representative case report

    Singh Gurpreet


    Full Text Available Abstract Background Although complications related to suprapubic cystostomies are well documented, there is scarcity of literature on safety issues involved in long-term care of suprapubic cystostomy in spinal cord injury patients. Case Presentation A 23-year-old female patient with tetraplegia underwent suprapubic cystostomy. During the next decade, this patient developed several catheter-related complications, as listed below: (1 Suprapubic catheter came out requiring reoperation. (2 The suprapubic catheter migrated to urethra through a patulous bladder neck, which led to leakage of urine per urethra. (3 Following change of catheter, the balloon of suprapubic catheter was found to be lying under the skin on two separate occasions. (4 Subsequently, this patient developed persistent, seropurulent discharge from suprapubic cystostomy site as well as from under-surface of pubis. (5 Repeated misplacement of catheter outside the bladder led to chronic leakage of urine along suprapubic tract, which in turn predisposed to inflammation and infection of suprapubic tract, abdominal wall fat, osteomyelitis of pubis, and abscess at the insertion of adductor longus muscle Conclusion Suprapubic catheter should be anchored securely to prevent migration of the tip of catheter into urethra and accidental dislodgment of catheter. While changing the suprapubic catheter, correct placement of Foley catheter inside the urinary bladder must be ensured. In case of difficulty, it is advisable to perform exchange of catheter over a guide wire. Ultrasound examination of urinary bladder is useful to check the position of the balloon of Foley catheter.

    Full Text Available Bladder probing is an invasive procedure that is often used by paediatric and other surgeons. We present a case who was ureter catheterized accidentally while placing a probe into the right ureter in an 18 months old female. If different catheter localization is determined during the examination, the process must be terminated immediately and the relevant specialist should be informed right away.

  8. Bladder calculi complicating intermittent clean catheterization. (United States)

    Amendola, M A; Sonda, L P; Diokno, A C; Vidyasagar, M


    Eight male patients on clean intermittent catheterization programs for neurogenic bladder dysfunction developed vesical calculi around pubic hairs inadvertently introduced into the bladder, acting as a nidus for incrustation. In three patients, the radiographic appearance of serpentine calcifications in the pelvis was highly consistent with calcareous deposits on strands of hair. Familiarity with this radiologic appearance should suggest the diagnosis in the appropriate clinical setting and help avoid misinterpretation of these calcifications, atypical of usual bladder stones.

    Nunes, G L; Nicolela Júnior, E L; Sousa, G M; Maldonado, G; Cano, M M; Esteves, C A; Braga, S L; Yaktine, H M; Feres, F


    To analyse the impact of the new cardiac catheterization techniques on the complication profile of these procedures. One thousand consecutive patients who underwent cardiac catheterization from August through December, 1989 (739 diagnostic and 201 therapeutic procedures), who were followed up until hospital discharge. Complications were classified accordingly to their type and severity, and were related to the procedure employed and to the left ventricular ejection fraction. There were no complications in 77.7% of the population studied. In the remaining 236 patients the incidence of mild, moderate and severe complications were, respectively: 11.2%, 7.3% and 3.8%. Severe vascular complications occurred in 0.5%, cardiac perforation requiring emergency surgical repair in 0.1%, severe arrhythmias in 1.4%, acute myocardial infarction in 0.4%, acute pulmonary edema in 0.3% and fatal events in 0.5% patients. Despite the increasing application of interventional techniques and the greater number of acutely ill patients referred to cardiac catheterization, these procedures have proved to be safe with a low complication rate.

  11. Arterial prehabilitation: can exercise induce changes in artery size and function that decrease complications of catheterization? (United States)

    Alkarmi, Amr; Thijssen, Dick H J; Albouaini, Khalled; Cable, N Timothy; Wright, D Jay; Green, Daniel J; Dawson, Ellen A


    Coronary angiography and angioplasty are common invasive procedures in cardiovascular medicine, which involve placement of a sheath inside peripheral conduit arteries. Sheath placement and catheterization can be associated with arterial thrombosis, spasm and occlusion. In this paper we review the literature pertaining to the possible benefits of arterial 'prehabilitation'--the concept that interventions aimed at enhancing arterial function and size (i.e. remodelling) should be undertaken prior to cardiac catheterization or artery harvest during bypass graft surgery. The incidence of artery spasm, occlusion and damage is lower in larger arteries with preserved endothelial function. We conclude that the beneficial effects of exercise training on both artery size and function, which are particularly evident in individuals who possess cardiovascular diseases or risk factors, infer that exercise training may reduce complication rates following catheterization and enhance the success of arteries harvested as bypass grafts. Future research efforts should focus directly on examination of the 'prehabilitation' hypothesis and the efficacy of different interventions aimed at reducing clinical complications of common interventional procedures.

  12. Internal Jugular Vein Catheterization with Seldinger Technique, previous Needle Puncture: Complications

    Directory of Open Access Journals (Sweden)

    Carrizo G


    Full Text Available Central venous catheterization (CVC is a common procedure performed daily for its outnumbered indications, complication rates range are up to 15%. The previous puncture with a fine needle with the Seldinger technique can reduce even more the possible complications, guaranteeing a high percentage of success. The objective was to determine the number of CVC per puncture with Seldinger technique performed by general surgery residents and identify number and type of mechanical complications, related to the residence year. A descriptive transversal cut study has been carried out, between March and November of 2014. A number of 243 patients were evaluated, observing that 41% of the cases were to measure CVP and hemodynamic monitoring; 76% of the punctures were done by 1º and 2º year residents, presenting only 10% on mechanic complications, most frequently on arterial puncture. In conclusion, previous puncture with needle with the Seldinger technique is safer, more secure, lower cost, and reduces the number of complications, it is a variant puncture under ultrasound guidance.

  13. Difficult male urethral catheterization: a review of different approaches

    Directory of Open Access Journals (Sweden)

    Carlos Villanueva


    Full Text Available PURPOSE: To review and compare the different methods for difficult male urethral catheterization described in selected literature. MATERIALS AND METHODS: A PubMed search was done with the terms "difficult", "failed", or "complications" and "urethral catheterization", "transurethral catheterization", "Foley catheter", "urethral catheter" or "filiforms and followers". All articles addressing the issue of difficult adult male urethral catheterization were included. RESULTS: Six main approaches were identified on the 14 articles included for review: 1 Passage of either a Glidewire, guide wire or filiform under direct vision; 2 Blind passage of a filiform, guide wire, Glidewire or hydrophilic catheter; 3 "The Peel-away® sheath placed on a cystoscope/resectoscope technique"; 4 "The rigid ureteroscope placed inside the 22F Foley technique"; 5 Suprapubic catheterization; and 6 "The instillation of 60 cc of saline through the catheter as it is advanced technique". CONCLUSION: There is a paucity of prospective data comparing the benefits, risks, success rates and complications of the different approaches for difficult Foley catheter placement. Our suggested approach starts with the initial attempt at urethral catheterization with an 18F coude and a 12F silicone catheter. If these fail, using a flexible cystoscope or the blind Glidewire technique are reasonable alternatives. If dilatation of a stricture is necessary, ureteric dilatators or a urethral balloon dilatator are recommended.

  18. Use of optimized ultrasound axis along with marked introducer needle to prevent mechanical complications of internal jugular vein catheterization

    Directory of Open Access Journals (Sweden)

    Tanmoy Ghatak


    Full Text Available Internal jugular vein (IJV catheterization is a routine technique in the intensive care unit. Ultrasound (US guided central venous catheter (CVC insertion is now the recommended standard. However, mechanical complications still occur due to non-visualization of the introducer needle tip during US guidance. This may result in arterial or posterior venous wall puncture or pneumothorax. We describe a new technique of (IJV catheterization using US, initially the depth of the IJV from the skin is measured in short-axis and then using real time US long-axis view guidance a marked introducer needle is advanced towards the IJV to the defined depth measured earlier in the short axis and the IJV is identified, assessed and cannulated for the CVC insertion. Our technique is simple and may reduce mechanical complications of US guided CVC insertion.

    Bahram Pishgoo


    Full Text Available Context In the past 20 to 30 years, the area of pediatric interventional cardiology has had noteworthy development. Technological revolutions have significantly progressed management of cardiovascular disease in both children and adults with congenital heart disease (CHD. This article reviews the current indications, techniques and complications of interventional therapy for CHD. Evidence Acquisition Training and publications in this field are rare. Overall, 64 article from January 1953 to February 2014 were studied. A total of 26 articles were involved in pediatric evaluation. Results There have been several catheter-based interventions for congenital heart disease. Percutaneous intervention in pediatric cardiac disease has been established in the past 2 to 3 decades. There are currently devices accepted for percutaneous closure of ASDs, patent ductus arteriosus (PDAs, and muscular ventricular septal defects (VSDs. The period of percutaneous valve implantation is just beginning, and the next few years may bring about advances in miniaturized valve distribution methods to allow insertion in smaller children. Conclusions Completely prepared catheterization laboratory, surgical holdup, and extracorporeal membrane oxygenation support capabilities must be accessible at any center to achieve interventional cardiac catheterization. Additional understanding of normal history of interventions more than 2 decade post process, novel strategies and methods will certainly lead to an increase in the methods for managing of congenital heart disease.

    Full Text Available Central venous catheters are frequently used for urgent patient resuscitation and for prolonged intravenous route requirements. However, the patient may be injured or may need additional intervention due to complications associated with catheter insertion. Various mechanical complications such as catheter malposition, arterial puncture, hemothorax and pneumothorax can be seen in 5-19% of patients and early recognition has a vital effect. Here, we present a case of pleural effusion leading to significant hypoxemia due to intimal injury to the superior vena cava which developed in the second day of catheter insertion.

    Flynn, Brian J; Larke, Robert J; Knoll, Paul B; Anderson, Kirk M; Siomos, Vassilis J; Windsperger, Andrew P


    To prospectively evaluate the new medical device Transurethral Suprapubic endo-Cystostomy (T-SPeC(®)), used for suprapubic catheter (SPC) placement via the transurethral (inside-to-out) approach, and examine the 30-day outcomes in the first US series. IRB approval was obtained for this prospective study. We evaluated the first 114 consecutive cases of SPC placement using the T-SPeC(®) device by a single surgeon at in a 20-month period. We excluded patients who underwent alternative approaches to suprapubic catheter placement including open abdominal approach (12) and percutaneous approach (5). Preoperative patient demographics, operative detail, success rate and 30-day complication rate were recorded. We successfully placed an 18 Fr suprapubic catheter using the T-SPeC(®) device in 98.2 % of patients. During the procedure, the capture housing was missed twice. The mean patient age was 56.6, BMI 29.4 kg/m(2), skin to bladder distance 6.7 cm and operative time 3.6 min. There were 12 postoperative complications within 30 days of the procedure including urinary tract infections (6), SPC exit site infection (2), SPC blockage (2) and catheter expulsion (2). There were no Clavien-Dindo grade III-IV complications such as re-operation, small bowel injury, hemorrhage or death. The T-SPeC(®) device is a novel, simple, accurate and minimally invasive device for SPC insertion from an inside-to-out approach. Our prospective study demonstrates that the T-SPeC(®) device can be placed safely and efficiently in a variety of patients with a need for urinary drainage.

    Peripheral catheterization is a technique that can be difficult in some patients. Some studies have recently described the use of ultrasound to guide the venous catheterization. To describe the success rate, time required, complications of ultrasound-guided peripheral venous catheterization. and patients and professionals satisfaction The search was performed in databases (Medline-PubMed, Cochrane Library, CINAHL and Cuiden Plus) for studies published about ultrasound-guided peripheral venous catheterization performed on patients that provided results on the success of the technique, complications, time used, patient satisfaction and the type of professional who performed the technique. A total of 21 studies were included. Most of them get a higher success rate 80% in the catheterization ecoguide and time it is not higher than the traditional technique. The Technical complications analyzed were arterial puncture rates and lower nerve 10%. In all studies measuring and comparing patient satisfaction in the art ecoguide is greater. Various professional groups perform the technique. The use of ultrasound for peripheral pipes has a high success rate, complications are rare and the time used is similar to that of the traditional technique. The technique of inserting catheters through ultrasound may be learned by any professional group performing venipuncture. Finally, it gets underscores the high patient satisfaction with the use of this technique. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

    Full Text Available Background: The optimal bladder management method should preserve renal function and minimize the risk of urinary tract complications. The present study is conducted to assess the overall incidence of urinary tract infections (UTI and other urological complications in spinal cord injury patients (SCI, and to compare the incidence of these complications with different bladder management subgroups. Materials and Methods: 545 patients (386 males and 159 females of traumatic spinal cord injury with the mean age of 35.4±16.2 years (range, 18 - 73 years were included in the study. The data regarding demography, bladder type, method of bladder management, and urological complications, were recorded. Bladder management methods included indwelling catheterization in 224 cases, clean intermittent catheterization (CIC in 180 cases, condom drainage in 45 cases, suprapubic cystostomy in 24 cases, reflex voiding in 32 cases, and normal voiding in 40 cases. We assessed the incidence of UTI and bacteriuria as the number of episodes per hundred person-days, and other urological complications as percentages. Results: The overall incidence of bacteriuria was 1.70 / hundred person-days. The overall incidenceof urinary tract infection was 0.64 / hundered person-days. The incidence of UTI per 100 person-days was 2.68 for indwelling catheterization, 0.34 for CIC, 0.34 for condom drainage, 0.56 for suprapubic cystostomy, 0.34 for reflex voiding, and 0.32 for normal voiding. Other urological complications recorded were urethral stricture (n=66, 12.1%, urethritis (n=78, 14.3%, periurethral abscess (n=45, 8.2%, epididymorchitis (n=44, 8.07%, urethral false passage (n=22, 4.03%, urethral fistula (n=11, 2%, lithiasis (n=23, 4.2%, hematuria (n=44, 8.07%, stress incontinence (n=60, 11%, and pyelonephritis (n=6, 1.1%. Clean intermittent catheterization was associated with lower incidence of urological complications, in comparison to indwelling catheterization. Conclusions

  8. Suprapubic versus transurethral bladder drainage following reconstructive pelvic surgery: a comparison of patient satisfaction and quality of life. (United States)

    Takase-Sanchez, Michelle M; Thompson, Jennifer C; Hale, Douglass S; Heit, Michael H


    To assess the differences in patient-reported, catheter-specific satisfaction and quality of life with either suprapubic or transurethral postoperative bladder drainage following reconstructive pelvic surgery. This was a prospective study of all eligible women who were scheduled to undergo reconstructive surgery requiring bladder drainage during the study period November 2013 to March 2015. Women who did not undergo the planned procedure(s) or did not require bladder drainage were excluded. The primary outcome was patient-reported quality of life using catheter-specific instruments including the Catheter-related Quality of Life (CIQOL) instrument, and a modified version of the Intermittent Self-Catheterization Questionnaire (ISC-Q), designed to evaluate aspects of catheter-related quality of life and satisfaction specific to the needs of the individual. A total of 178 women were analyzed, 108 in the transurethral catheter group and 70 in the suprapubic group. Women with suprapubic bladder drainage had higher quality of life and satisfaction scores than women with transurethral bladder drainage as measured by the ISC-Q (68.31 ± 16.87 vs. 54.04 ± 16.95, mean difference 14.27, 95 % CI 9.15 - 19.39). There was no difference in quality of life by the CIQOL. After regression analysis, women with suprapubic bladder drainage were more satisfied with their catheter-specific needs despite longer duration of catheter use, more concurrent continence surgery, and higher trait anxiety. Differences in catheter-specific quality of life and patient satisfaction scores favoring suprapubic bladder drainage support its continued use in appropriately selected women for treatment of temporary postoperative urinary retention after reconstructive pelvic surgery.

  9. Suprapubic-vaginocutaneous fistula 18 years after a bladder-neck suspension. (United States)

    Giles, Dobie L; Davila, G Willy


    Several complications are associated with healing after pelvic reconstructive surgery for stress urinary incontinence. These include infection, hemorrhage, erosion, and fistula formation. A 67-year-old woman presented with simultaneously draining vaginal and suprapubic sinuses. Examination revealed a vagino-abdominal fistula. Surgical excision found an abscess around synthetic material from a previous bladder-neck suspension. Unusual fistulation can occur remotely from anti-incontinence surgery, especially when graft materials are used.

  13. Laparoscopy-assisted cutaneous ureterostomy at suprapubic creaseline facilitates subsequent reimplantation

    Directory of Open Access Journals (Sweden)

    Md. Jafrul Hannan


    Full Text Available Background: Cutaneous ureterostomy is still practiced despite a trend towards primary surgical correction for obstructive or refluxive uropathy. For future open reimplantation, ureterostomy can be created by minimal invasive technique at the end(s of the suprapubic creaseline. Materials and Methods: From 1 January 2009 to 31 July 2012, seven children were treated with laparoscopy-assisted cutaneous ureterostomy followed by ureteric reimplantation. Indications were primary obstructive megaureter 3, hugely dilated ureters with reflux 3 and posterior urethral valve with poor general health 1. The distal manoeuverable part of tortuous ureter was pulled to the surface at either end of suprapubic creaseline to create the stoma. During reimplantation, this stoma was dismembered and brought inside urinary bladder obviating the need for stoma-site repair. Results: Mean age was 4.6 ± 2.8 years with six males. There were three bilateral cases with total 10 lesions. Mean operating time was 39.8 ± 12.5 minutes. Mean follow-up was 1.7 ± 0.8 years and except for peri-stomal excoriations no major complication occurred. All these were reimplanted 6-12 months after ureterostomy and faring well except in one case. Conclusions: Laparoscopy-assisted cutaneous ureterostomy can be fashioned at suprapubic creaseline to facilitate future reimplantation without much jeopardy and extra scar.

  14. Delayed Presentation of Small Bowel Injury During Suprapubic Catheterisation

    Directory of Open Access Journals (Sweden)

    Jackson BL


    Full Text Available We present a case of small intestine injury resulting from suprapubic catheter insertion. This case is of particular interest for three reasons. Firstly, the presentation of the injury was delayed by three months, until the time of the first catheter exchange. Secondly, the injury was managed conservatively, without surgical exploration. Finally, the injury occurred using a newer, Seldinger-type suprapubic catheter insertion kit.

  15. Does perception of catheterization limit its use in pediatric UTI? (United States)

    Selekman, Rachel E; Sanford, Melissa T; Ko, Lauren N; Allen, I Elaine; Copp, Hillary L


    Urinary tract infections (UTIs) affect 3-8% of febrile children annually, but correctly diagnosing UTI in young children can present a challenge. Diagnosis requires a non-contaminated urine sample, which requires catheterization or suprapubic aspiration in infants and young children that have not completed toilet training. To improve adherence to these guidelines, it is critical to understand the barriers to urine testing and catheterization. The purpose of this study was to investigate parental perception of pediatric UTI evaluation to better understand factors that impede urine testing prior to treatment of suspected UTI. We conducted an electronic, cross-sectional survey via social media targeting parents of children with a history of UTI. Participants were queried regarding demographics, urine specimen collection method, factors influencing urine collection method, and perception of the experience. Multivariable logistic regression was used to assess factors associated with catheterization distress and urine testing. Of 2726 survey respondents, > 80% were female and White; 74% of the children with a history of UTI were female. Fifty-six percent of parents perceived extreme distress with catheterization. Among parents whose child was catheterized, extreme distress was less likely perceived if the parent was White (OR 0.6, 95% CI 0.4-0.9) or if the child was circumcised (OR 0.7, 95% CI 0.4-0.98). Among those whose child was not catheterized, extreme distress was more likely if parents had a college education (OR 3.2, 95% CI 2.2-4.5) and the child was more than 1 year old (OR 1.7, 95% CI 1.2-2.5). Catheterization was less likely to be withheld if parents had a college education (OR 0.1, 95% CI 0.1-0.2), and if the child was circumcised (OR 0.5, 95% CI 0.3-0.8) or had only one UTI (OR 0.6, 95% CI 0.4-0.8) (Table). Parental education level, child age, and circumcision status play an important role in the subjective distress associated with catheterization. This

    Full Text Available Abstract Background A central venous catheter (CVC currently represents the most frequently adopted intravenous line for patients undergoing infusional chemotherapy and/or high-dose chemotherapy with hematopoietic stem-cell transplantation and parenteral nutrition. CVC insertion represents a risk for pneumothorax, nerve or arterial punctures. The aim of this prospective observational study was to explore the safety and efficacy of CVC insertion under ultrasound (US guidance and to confirm its utility in clinical practice in cancer patients. Methods Consecutive adult patients attending the oncology-hematology department were eligible if they had solid or hematologic malignancies and required CVC insertion. Four types of possible complication were defined a priore: mechanical, thrombotic, infection and malfunctioning. The patient was placed in Trendelenburg's position, a 7.5 MHZ puncturing US probe was placed in the supraclavicular site and a 16-gauge needle was advanced under real-time US guidance into the last portion of internal jugular vein. The Seldinger technique was used to place the catheter, which was advanced into the superior vena cava until insertion into right atrium. Within two hours after each procedure, an upright chest X-ray and ultrasound scanning were carried out to confirm the CVC position and to rule out a pneumotorax. CVC-related infections, symptomatic vein thrombosis and malfunctioning were recorded. Results From December 2000 to January 2009, 1,978 CVC insertional procedures were applied to 1,660 consecutive patients. The procedure was performed 580 times in patients with hematologic malignancies and 1,398 times those with solid tumors. A single-needle puncture of the vein was performed on 1,948 of 1,978 procedures (98.48%; only eighteen attempts among 1,978 failed (0.9%. No pneumotorax, no major bleeding, and no nerve puncture were reported; four cases (0.2% showed self-limiting hematomas. The mean lifespan of CVC was 189

  18. Urethral (indwelling or intermittent) or suprapubic routes for short-term catheterisation in hospitalised adults. (United States)

    Kidd, Emily A; Stewart, Fiona; Kassis, Nadine C; Hom, Emily; Omar, Muhammad Imran


    Indwelling urethral catheters are often used for bladder drainage in hospital. Urinary tract infection is the most common hospital-acquired infection, and a common complication of urinary catheterisation. Pain, ease of use and quality of life are important to consider, as well as formal economic analysis. Suprapubic catheterisation can also result in bowel perforation and death. To determine the advantages and disadvantages of alternative routes of short-term bladder catheterisation in adults in terms of infection, adverse events, replacement, duration of use, participant satisfaction and cost effectiveness. For the purpose of this review, we define 'short-term' as intended duration of catheterisation for 14 days or less. We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process,, WHO ICTRP and handsearching of journals and conference proceedings (searched 26 February 2015), CINAHL (searched 27 January 2015) and the reference lists of relevant articles. We included all randomised and quasi-randomised trials comparing different routes of catheterisation for short-term use in hospitalised adults. At least two review authors extracted data and performed 'Risk of bias' assessment of the included trials. We sought clarification from the trialists if further information was required. In this systematic review, we included 42 trials.Twenty-five trials compared indwelling urethral and suprapubic catheterisation. There was insufficient evidence for symptomatic urinary tract infection (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.61 to 1.69; 5 trials, 575 participants; very low-quality evidence). Participants with indwelling catheters had more cases of asymptomatic bacteriuria (RR 2.25, 95% CI 1.63 to 3.10; 19 trials, 1894 participants; very low quality evidence) and more participants reported pain (RR 5.62, 95% CI

  3. Emergent Median Sternotomy for Mediastinal Hematoma: A Rare Complication following Internal Jugular Vein Catheterization for Chemoport Insertion—A Case Report and Review of Relevant Literature

    Directory of Open Access Journals (Sweden)

    Saptarshi Biswas


    Full Text Available Mediastinal hematoma is a rare complication following insertion of a central venous catheter with only few cases reported in the English literature. We report a case of a 71-year-old female who was admitted for elective chemoport placement. USG guided right internal jugular access was attempted using the Seldinger technique. Resistance was met while threading the guidewire. USG showed a chronic clot burden in the RIJ. A microvascular access was established under fluoroscopic guidance. Rest of the procedure was completed without any further issues. Following extubation, the patient complained of right-sided chest pain radiating to the back. Chest X-ray revealed a contained white out in the right upper lung field. She became hemodynamically unstable. Repeated X-ray showed progression of the hematoma. Median Sternotomy showed posterior mediastinal hematoma tracking into right pleural cavity. Active bleeding from the puncture site at RIJ-SCL junction was repaired. Patient had an uneventful recovery. Injury to the central venous system is the result of either penetrating trauma or iatrogenic causes as in our case. A possible explanation of our complication may be attributed to the forced manipulation of the dilator or guidewire against resistance. Clavicle and sternum offer bony protection to the underlying vital venous structures and injuries often need sternotomy with or without neck extension. Division of the clavicle and disarticulation of the sternoclavicular joint may be required for optimum exposure. Meticulous surgical technique, knowledge of the possible complications, and close monitoring in the postprocedural period are of utmost importance. Chest X-ray showed to be routinely done to detect any complication early.

    Kasatkin, A. A.; Urakov, A. L.; Nigmatullina, A. R.


    By ultrasound scanning it was determined that respiratory movements made by chest of healthy and sick person are accompanied by respiratory chest rise of internal jugular veins. During the exhalation of an individual diameter of his veins increases and during the breath it decreases down to the complete disappearing if their lumen. Change of the diameter of internal jugular veins in different phases can influence significantly the results of vein puncture and cauterization in patients. The purpose of this research is development of the method increasing the efficiency and safety of cannulation of internal jugular veins by the ultrasound visualization. We suggested the method of catheterization of internal jugular veins by the ultrasound navigation during the execution of which the puncture of venous wall by puncture needle and the following conduction of J-guide is carried out at the moment of patient's exhalation. This method decreases the risk of complications development during catheterization of internal jugular vein due to exclusion of perforating wound of vein and subjacent tissues and anatomical structures.

  6. Is an adjustment by transurethral surgery simultaneously needed during the suprapubic open prostatectomy? (United States)

    Shin, Yu Seob; Zhang, Li Tao; Zhao, Chen; You, Jae Hyung; Park, Jong Kwan


    Purpose To compare suprapubic open prostatectomy (SOP) and a novel SOP with transurethral adjustment of residual adenoma and bleeding (TURARAB) for large sized prostates. Methods Between March 2010 and March 2014, 49 patients with symptomatic BPH (>100 g) were scheduled for SOP or SOP with TURARAB. The patients were subdivided into two groups. In Group I, each patient underwent SOP. In Group II, each patient underwent SOP with TURARAB. Additional transurethral resection of residual adenoma and bleeding control were done through the urethra after enucleation of the prostate adenoma by SOP. Prior to intervention, all patients were analyzed by preoperative complete blood count, blood chemistry, prostate specific antigen, International Prostate Symptom Scores, and transrectal ultrasound of the prostate and uroflowmetry. SOP was performed by a suprapubic transvesical approach via a midline incision. The bladder neck mucosa was circularly incised to expose the prostate adenoma, and the plane between the adenoma and surgical capsule was developed by finger dissection. In addition, in Group II TURARAB was performed using Urosol. Postoperative outcome data were compared in the 1st month and 3rd month. Results There were no statistically significant differences in baseline characteristics between the two groups. Group I required a longer operative time than Group II. Blood transfusion during the operation was unnecessary due to the short amount of time available to control arterial bleeding in the prostatic fossa leading to a marked decrease in perioperative bleeding in Group II. Postoperative voiding function improved significantly in both groups. Conclusions Even for large prostate glands, our novel procedure appears to be an effective and safe operation to reduce operation time, bleeding, and complications. PMID:26157764

  7. An abdominal wall simulator for testing suprapubic urinary catheters. (United States)

    Coveney, V A; Gröver, D


    Urinary catheters (drainage tubes) are in widespread use. The most common type of long-term catheter is the Foley, which is made from natural or synthetic rubber. Foley catheters are passed into the bladder via the urethra or the suprapubic puncture channel (through the abdominal wall). A simulator for the abdominal wall has been developed to simulate aspects of the interaction between it and a suprapubic catheter. The simulator is based on a slab of ultrasoft elastomer with tensionable reinforcing polyamide filaments. The behaviour of the simulator has been compared with data published. A soft membrane (contact pressure) transducer (SMT) was used and novel instrumented 'tongs' for lateral indentation of the puncture track giving indentation stiffness. Slab materials were used with shear moduli of 0.1 and 0.021 MPa. Two filament-tensioning methods were used: by clamping to a winding mechanism and by weights. The combination of the softer slab material and tensioning by weights gave good conformity to physiological data; other combinations did not.

    Children with heart disease may require repeated X-Ray cardiac catheterization procedures, are more radiosensitive, and more likely to survive to experience oncologic risks of medical radiation. Cardiovascular magnetic resonance (CMR) is radiation-free and offers information about structure, function, and perfusion but not hemodynamics. We intend to perform complete radiation-free diagnostic right heart catheterization entirely using CMR fluoroscopy guidance in an unselected cohort of pediatric patients; we report the feasibility and safety. We performed 50 CMR fluoroscopy guided comprehensive transfemoral right heart catheterizations in 39 pediatric (12.7 ± 4.7 years) subjects referred for clinically indicated cardiac catheterization. CMR guided catheterizations were assessed by completion (success/failure), procedure time, and safety events (catheterization, anesthesia). Pre and post CMR body temperature was recorded. Concurrent invasive hemodynamic and diagnostic CMR data were collected. During a twenty-two month period (3/2015 - 12/2016), enrolled subjects had the following clinical indications: post-heart transplant 33%, shunt 28%, pulmonary hypertension 18%, cardiomyopathy 15%, valvular heart disease 3%, and other 3%. Radiation-free CMR guided right heart catheterization attempts were all successful using passive catheters. In two subjects with septal defects, right and left heart catheterization were performed. There were no complications. One subject had six such procedures. Most subjects (51%) had undergone multiple (5.5 ± 5) previous X-Ray cardiac catheterizations. Retained thoracic surgical or transcatheter implants (36%) did not preclude successful CMR fluoroscopy heart catheterization. During the procedure, two subjects were receiving vasopressor infusions at baseline because of poor cardiac function, and in ten procedures, multiple hemodynamic conditions were tested. Comprehensive CMR fluoroscopy guided right heart catheterization was feasible and

    Schmutz, J L; Granel, F; Reichert-Penetrat, S; Danchin, N; Barbaud, A


    INCREASING INCIDENCE: The development of new interventional techniques in radiology, particularly angioplasty of the coronary arteries, has lead to a rise in the incidence of radioderimitis. Clinical presentations vary from skin rash to necrosis and chronic ulceration. Telangiectasic atrophy and poikilodermitis are also observed. CASE REPORTS IN THE LITERATURE: Twenty-three cases of radiodermitis after cardiac catheterism have been reported in the literature. Mean delay to onset after the first radiology examination varies from 15 days to 10 years. TO REDUCE THE RISK: The main risk factor is a long duration of scopy using the same incidence. Use of older non-digitalized radiology machines also increases the risk. Physicians performing endovascular procedures should be aware of the risk of radiodermitis after angioplasy and implement radioprotective measures. RETROSPECTIVE DIAGNOSIS: Patients who develop localized pigmentation disorders and/or telangiectasies should be questioned concerning prior, often forgotten, radiology examinations.

  11. A Rare Case of Massive Hemothorax due to Central Venous Catheterization Treated with Angiographic Stent Implantation

    Directory of Open Access Journals (Sweden)

    Jung-Min Bae

    Full Text Available In critically ill patients, centeral venous catheterization is a widely used procedure for fluid resuscitation, massive transfusion, total parenteral nutrition, central venous pressure monitoring and hemodialysis. However, many complications are associated with central venous catheterization. Among these complications, hemothorax is rare but fatal. We recently experienced a 32-year-old female diagnosed with hemothorax due to subclavian catheterization who was successfully treated with angiographic intervention. There are no absolute indications of surgery or interventional treatment in such cases. Multicenter studies and consensus are necessary to determine the proper treatment for hemothorax due to central venous catheterization. Angiographic treatment is rarely used for this uncommon complication of subclavian catheterization. We describe a rare case with a review of the literature.

  12. Segmentation of the prostate from suprapubic ultrasound images. (United States)

    Yu, Yongjian; Molloy, Janelle A; Acton, Scott T


    We present a technique for semiautomated segmentation of human prostates using suprapubic ultrasound (US) images. In this approach, a speckle reducing anisotropic diffusion (SRAD) is applied to enhance the images and the instantaneous coefficient of variation (ICOV) is utilized for edge detection. Segmentation is accomplished via a parametric active contour model in a polar coordinate system that is tailored to the application. The algorithm initially approximates the prostate boundary in two stages. First a primary contour is detected using an elliptical model, followed by a primary contour optimization using an area-weighted mean-difference binary flow geometric snake model. The algorithm was assessed by comparing the computer-derived contours with contours produced manually by three sonographers. The proposed method has application in radiation therapy planning and delivery, as well as in automated volume measurements for ultrasonic diagnosis. The average root mean square discrepancy between computed and manual outlines is less than the inter-observer variability. Furthermore, 76% of the computer-outlined contour is less than 1 sigma manual outline variance away from "true" boundary of prostate. We conclude that the methods developed herein possess acceptable agreement with manually contoured prostate boundaries and that they are potentially valuable tools for radiotherapy treatment planning and verification.

    To retrospectively study demographic, clinical and hospital outcomes in patients who developed RPH following cardiac catheterization. Charts of patients with RPH from cardiac catheterization, between January 1, 2000 and July 30, 2005 were reviewed and compared with two control groups (Grp-I, 90 patients with local groin complications and Grp-II, 98 patients with no bleeding complications). 31 cases of RPH (0.13%) were identified with 84% females. Most common presentation was hypotension (87%) and hemoglobin drop (96%). CT scan was the diagnostic modality in 93% cases. The mean body surface area in RPH group (1.77 ± .23) was significantly lower than in control group I (1.93 ± .28) and II (1.98 ± .27). The use of larger sheath size was significantly higher in the RPH group (61.3%) than control groups I (26.7%) and II (21.4%). Left groin access was significantly more in RPH group (16.1%) and control group I (17.8) than control group II (0%). The use of antiplatelets and anticoagulants were significantly higher in the RPH group. 13% of patients with RPH were treated surgically. The average hospital stay was 8.6 days, 4.5 days and 3.5 days and mortality 12.9%, 3.3% and 1% in RPH group, control group I and II respectively. Our study is the second largest series of RPH following cardiac catheterization and predicts female gender, large sheath size, left groin access and low body surface area as risk factors for RPH. ©2010, Wiley Periodicals, Inc.

    Full Text Available BACKGROUND AND OBJECTIVES: In this study, we aimed to clarify the importance of residency grade and other factors which influence the success of thoracic epidural catheterization in thoracotomy patients. METHODS: After the ethical committee approval, data were recorded retrospectively from the charts of 415 patients. All patients had given written informed consent. The thoracic epidural catheterization attempts were divided into two groups as second-third year (Group I and fourth year (Group II according to residency grade. We retrospectively collected demographic data, characteristics of thoracic epidural catheterization attempts, and all difficulties and complications during thoracic epidural catheterization. RESULTS: Overall success rate of thoracic epidural catheterization was similar between the groups. Levels of catheter placement, number and duration of thoracic epidural catheterization attempts were not different between the groups (p > 0.05. Change of needle insertion level was statistically higher in Group II (p = 0.008, whereas paresthesia was significantly higher in Group I (p = 0.007. Dural puncture and postdural puncture headache rates were higher in Group I. Higher body mass index and level of the insertion site were significant factors for thoracic epidural catheterization failure and postoperative complication rate and those were independence from residents' experience (p < 0.001, 0.005. CONCLUSION: Body mass index and level of insertion site were significant on thoracic epidural catheterization failure and postoperative complication rate. We think that residents' grade is not a significant factor in terms overall success rate of thoracic epidural catheterization, but it is important for outcome of these procedures.

The complications (28.6% of the sample were mainly infection and vesicolithiasis. There were high scores for social support in relation to people that were part of the patient's social support.CONCLUSION: All of them noticed great support from the family, but not from the society in general. The difficulties were related to the lack of equipment and inadequate infrastructure, leading to changes that increased urologic complications.

  20. Urethral versus suprapubic catheter: choosing the best bladder management for male spinal cord injury patients with indwelling catheters. (United States)

    Katsumi, H K; Kalisvaart, J F; Ronningen, L D; Hovey, R M


    Bladder management for male patients with spinal cord injury (SCI) challenges the urologist to work around physical and social restrictions set forth by each patient. The objective of this study was to compare the complications associated with urethral catheter (UC) versus suprapubic tube (SPT) in patients with SCI. A retrospective review of records at Long Beach Veterans Hospital was carried out to identify SCI patients managed with SPT or UC. Chart review identified morbidities including urinary tract infection (UTI), bladder stones, renal calculi, urethral complications, scrotal abscesses, epididymitis, gross hematuria and cancer. Serum creatinine measurements were evaluated to determine whether renal function was maintained. In all, 179 patients were identified. There was no significant difference between the two catheter groups in any areas in which they could be compared. There were catheter-specific complications specific to each group that could not be compared. These included erosion in the UC group and urethral leak, leakage from the SPT and SPT revision in the SPT group. Average serum creatinine for the UC and SPT groups was 0.74 and 0.67 mg per 100 ml, respectively. SCI patients with a chronic catheter have similar complication rates of UTIs, recurrent bladder/renal calculi and cancer. Urethral and scrotal complications may be higher with UC; however, morbidity from SPT-specific procedures may offset benefits from SPT. Serum creatinine was maintained in both groups. Overall, bladder management for patients with chronic indwelling catheters should be selected on the basis of long-term comfort for the patient and a physician mind-set that allows flexibility in managing these challenges.

  1. The Suprapubic Dermoadipose Flap for Aesthetic Reshaping of the Postpregnancy Abdomen. (United States)

    Mayer, Horacio F; Loustau, Hugo D


    Postpregnancy full-length diastasis of the recti abdominis muscles is a common condition occasionally associated with atrophy of the subcutaneous fat located at the midline above and below the umbilicus. The authors report a preliminary clinical experience with the suprapubic flap to prevent the late postoperative contour deformities of the postpregnancy abdomen. Between January 2005 and January 2015, all female patients undergoing abdominoplasty with the suprapubic flap were included in the present study. Electronic clinical records were reviewed to analyze the patients' ages, body mass index (BMI) scores, pregnancies, risk factors, and operative times, followed by a telephone-based survey to measure patient satisfaction. Twenty-two patients were included. Their ages ranged from 19 to 36 years (mean, 27 years) and their BMI ranged from 17.5 to 22.5 kg/m2 (mean, 20.5 kg/m2). Postoperative follow up ranged from 12 months to 10 years (mean, 89 months). All patients had experienced at least one pregnancy and many of them multiple or twin pregnancies. Umbilical hernias were present in 18 patients. There were 5 unusual cases: one hematoma, one seroma, and three cases of hypertrophic scarring. Thirteen additional minutes were required, on average, to associate the flap. All patients were satisfied or very satisfied with the results. The suprapubic dermoadipose flap is an effective option to prevent the midline depression that would otherwise remain on the hypogastric region of postpregnant slim women with midline fat tissue atrophy. 4.

  3. Caring for the adult with congenital heart disease in an adult catheterization laboratory by pediatric interventionalists--safety and efficacy. (United States)

    Sutton, Nicole J; Greenberg, Mark A; Menegus, Mark A; Lui, George; Pass, Robert H


    The purpose of this study is to describe the outcomes of cardiac catheterizations performed by pediatric interventional cardiologists in an adult catheterization laboratory on adult patients with congenital heart disease (CHD). With improved survival rates, the number of adults with CHD increases by ∼5%/year; this population often requires cardiac catheterization. From January 2005 to December 2009, two groups of patients were identified, an adult group (>21 years) and an adolescent group (13-21 years), who had catheterizations performed by pediatric interventional staff. Fifty-seven catheterizations were performed in 53 adults, while 59 were performed in 47 adolescents. The male to female ratio differed significantly between groups; only 15/53 (28%) of adults were male vs. 26/47 (55%) of adolescents (P =.006). Among adults, 27 had previously corrected CHD, 16 with atrial septal defect (ASD), and six with patent foramen ovale (PFO). This differed significantly from the adolescents, where only 30 had previously corrected CHD, seven with ASD, and one with PFO (P =.012). Among adults who were catheterized, interventions were performed on 28/53 (53%). All interventions were successful and included ASD/PFO closure, patent ductus arteriosus occlusion, coarctation dilation, pulmonary artery dilations, and one saphenous vein graft aneurysm closure. Nineteen adults had coronary angiography performed by adult interventionalists in consult with pediatric interventionalists. Two complications occurred among adults (3.8%) vs. one complication (2%; P = 1) among adolescents. No femoral vessel complications or catheterization-associated mortality occurred. Cardiac catheterizations can be performed effectively and safely in adults with CHD by pediatric interventional cardiologists in an adult catheterization laboratory. © 2012 Wiley Periodicals, Inc.

  4. Arterial thrombotic occlusions following percutaneous catheterization in infants and children: local thrombolytic therapy with urokinase

    Energy Technology Data Exchange (ETDEWEB)

    Kim, Yong Joo [Kyungpook National University College of Medicine, Daegu (Korea, Republic of)


    Six cases of right external iliac and common femoral arterial thrombotic occlusions following transfemoral cardiac catheterization were found among the 117 infants and children with congenital heart disease. Physical findings of arterial thrombosis were lower extremity coldness and absence of femoral pulse, which appeared just after cardiac catheterization. Transcatheter local intrathrombotic infusion of Urokinase were done with 50000 IU bolus doses and 40000-50000 IU/h running doses. All 6 cases showed complete thrombolysis and re-establishment of femoral circulation. Three cases developed bleeding from arterial puncture sites, and were subsequently controlled properly by compression. No other complication was found. Our results suggest that local thrombolytic therapy with Urokinase is effective treatment method without significant complication for the infants and children with fresh thrombotic occlusions following cardiac catheterization and angiography.

    Kocum, Aysu; Sener, Mesut; Calıskan, Esra; Bozdogan, Nesrin; Atalay, Hakan; Aribogan, Anis


    To evaluate the clinical success rate, safety, and usefulness for intraoperative central venous pressure monitoring, and the intravenous access of the supraclavicular subclavian vein approach when compared with the infraclavicular subclavian vein approach and the internal jugular vein approach for central venous catheterization during open-chest cardiac surgery. A prospective, randomized, single-center study. A university hospital. One hundred ninety-five patients scheduled for open-chest cardiac surgery. The study population consisted of patients for whom central vein catheterization was intended during cardiac surgery. Patients were randomized to 3 groups according to the route of central vein catheterization: the supraclavicular group: the supraclavicular approach for the subclavian vein (n = 65); the infraclavicular group: the infraclavicular approach for the subclavian vein (n = 65); and the jugular group: the internal jugular vein approach (n = 65). After the induction of anesthesia, central venous catheterization was performed according to the assigned approach. The success rates for the assigned approach were 98%, 98%, and 92% for the supraclavicular, infraclavicular, and jugular groups, respectively (p > 0.05). The success rates in the first 3 attempts in patients who were catheterized successfully according to the assigned approach were 96%, 100%, and 96% for the supraclavicular, infraclavicular, and jugular groups, respectively (p > 0.05). There was no difference among groups in catheter insertion time (p > 0.05). After sternal retraction, central venous pressure trace loss and difficulty in fluid infusion were significantly more frequent in the infraclavicular group (21%) when compared with the supraclavicular (3%) and jugular groups (0%) (p = 0.01). There was no difference among groups in terms of catheter malposition, complications during catheterization, and rate of catheter-related infection. The supraclavicular approach for subclavian vein

    Abdominal incision complications are a major source of morbidity after caesarean delivery. Repair of the superficial fascial system may avert local complications after caesarean delivery by minimising tension to the skin and increasing the initial biomechanical strength of wound which has the potential to decrease early wound dehiscence and as a by-product correct suprapubic bulging.

  7. Suprapubic tube versus urethral catheter drainage after robot-assisted radical prostatectomy: a systematic review and meta-analysis. (United States)

    Jian, Zhongyu; Feng, Shijian; Chen, Yuntian; Wei, Xin; Luo, Deyi; Li, Hong; Wang, Kunjie


    Prostate cancer is one of the most common cancers in the elderly population. The standard treatment is radical prostatectomy (RARP). However, urologists do not have consents on the postoperative urine drainage management (suprapubic tube (ST)/ urethral catheter (UC)). Thus, we try to compare ST drainage to UC drainage after robot-assisted radical prostatectomy regarding to comfort, recovery rate and continence using the method of meta-analysis. A systematic search was performed in Dec. 2017 on PubMed, Medline, Embase and Cochrane Library databases. The authors independently reviewed the records to identify studies comparing ST with UC of patients underwent RARP. Meta-analysis was performed using the extracted data from the selected studies. Seven studies, including 3 RCTs, with a total of 946 patients met the inclusion criteria and were included in our meta-analysis. Though there was no significant difference between the ST group and the UC group on postoperative pain (RR1.73, P 0.20), our study showed a significant improvement on bother or discomfort, defined as trouble in hygiene and sleep, caused by catheter when compared two groups at postoperative day (POD) 7 in ST group (RR2.05, P 0.006). There was no significant difference between the ST group and UC group on urinary continence (RR0.98, P 0.74) and emergency department visit (RR0.61, P 0.11). The rates of bladder neck contracture and other complications were very low in both groups. Compared to UC, ST showed a weak advantage. So it might be a good choice to choose ST over RARP.

  8. Radial artery occlusion after transradial approach to cardiac catheterization. (United States)

    Wagener, John F; Rao, Sunil V


    Radial artery occlusion (RAO) is the most common complication of the transradial approach (TRA) to cardiac catheterization, with a reported incidence between 0.8 % and 30 %. RAO is likely the result of acute thrombus formation and complicated by neointimal hyperplasia. Most RAO are asymptomatic with rare cases of acute hand or digit ischemia reported in the literature. The role of testing for dual circulation to the hand in determining the safety of TRA as it relates to symptomatic RAO is controversial; however, modifiable risk factors like low sheath-to-artery ratio, adequate anticoagulation, and non-occlusive ("patent") hemostasis are likely to prevent RAO. This review examines the incidence of RAO, potential mechanisms leading to RAO, and strategies to prevent and treat RAO.

  9. A new technique for long time catheterization of sacral epidural canal in rabbits. (United States)

    Erkin, Yüksel; Aydın, Zeynep; Taşdöğen, Aydın; Karcı, Ayşe


    In this study we aimed to develop a simple and practical technique for chronic sacral epidural catheterization of rabbits. We included ten rabbits weighing 2-2.5 kg in the study. After anesthesia and analgesia, we placed an epidural catheter by a 2 cm longitudinal skin incision in the tail above the sacral hiatus region. We confirmed localization by giving 1% lidocaine (leveling sensory loss and motor function loss of the lower extremity). The catheter was carried forward through a subcutaneous tunnel and fixed at the neck. Chronic caudal epidural catheter placement was succesful in all rabbits. The catheters stayed in place effectively for ten days. We encountered no catheter complications during this period. The localization of the catheter was reconfirmed by 1% lidocaine on the last day. After animals killing, we performed a laminectomy and verified localization of the catheter in the epidural space. Various methods for catheterization of the epidural space in animal models exist in the literature. Epidural catheterization of rabbits can be accomplished by atlanto-occipital, lumbar or caudal routes by amputation of the tail. Intrathecal and epidural catheterization techniques defined in the literature necessitate surgical skill and knowledge of surgical procedures like laminectomy and tail amputation. Our technique does not require substantial surgical skill, anatomical integrity is preserved and malposition of the catheter is not encountered. In conclusion, we suggest that our simple and easily applicable new epidural catheterization technique can be used as a model in experimental animal studies.

  10. Different transseptal puncture for different procedures: Optimization of left atrial catheterization guided by transesophageal echocardiography

    Directory of Open Access Journals (Sweden)

    Andrea Radinovic


    Full Text Available Background: Left atrial catheterization through transseptal puncture is frequently performed in cardiac catheterization procedures. Appropriate transseptal puncture is critical to achieve procedural success. Aims: The aim of the study is to evaluate the feasibility of selective transseptal punctures, using a modified radiofrequency (RF transseptal needle and transesophageal echocardiography (TEE, in different types of procedures that require specific sites of left atrial catheterization. Setting and Design: This was an observational trial in a cardiac catheterization laboratory of a teaching hospital. Materials and Methods: Patients undergoing different percutaneous procedures requiring atrial transseptal puncture such as atrial fibrillation (AF ablation, left atrial appendage (LAA occlusion, and mitral valve repair were included in the study. All procedures were guided by TEE and an RF transseptal needle targeting a specific region of the septum to perform the puncture. Statistical Analysis: The statistical analysis was descriptive only. Results: RF-assisted transseptal punctures were performed in six consecutive patients who underwent AF ablation (two patients, LAA closure (two patients, and mitral valve repair (two patients. In all patients, transseptal punctures were performed successfully at the desired site. No adverse events or complications were observed. Conclusions: Selective transseptal puncture, using TEE and an RF needle, is a feasible technique that can be used in multiple approaches requiring a precise site of access for left atrial catheterization.

    Central venous catheterization is an important procedure for infant patients for a number of different purposes, including nutritional support, surgical operation, hemodynamic monitoring, and multiple lines for critical care medications. Subclavian vein catheterization (SVC) is one of the central vein catheterization techniques. SVC can be performed from 4 different locations: right supraclavicular (RSC), left supraclavicular (LSC), right infraclavicular (RIC), and left infraclavicular (LIC)....

  17. Influence of Mechanical Ventilation on the Incidence of Pneumothorax During Infraclavicular Subclavian Vein Catheterization: A Prospective Randomized Noninferiority Trial. (United States)

    Kim, Eugene; Kim, Hyun Joo; Hong, Deok Man; Park, Hee-Pyoung; Bahk, Jae-Hyon


    It remains unclear whether we have to interrupt mechanical ventilation during infraclavicular subclavian venous catheterization. In practice, the clinicians' choice about lung deflation depends on their own discretion. The purpose of this study was to assess the influence of mechanical ventilation on the incidence of pneumothorax during infraclavicular subclavian venous catheterization. A total of 332 patients, who needed subclavian venous catheterization, were randomly assigned to 1 of the 2 groups: catheterizations were performed with the patients' lungs under mechanical ventilation (ventilation group, n = 165) or without mechanical ventilation (deflation group, n = 167). The incidences of pneumothorax and other complications such as arterial puncture, hemothorax, or catheter misplacements and the success rate of catheterization were compared. The incidences of pneumothorax were 0% (0/165) in the ventilation group and 0.6% (1/167) in the deflation group. The incidence of pneumothorax in the deflation group was 0.6% higher than that in the ventilation group and the 2-sided 90% confidence interval for the difference was (-1.29% to 3.44%). Because the lower bound for the 2-sided 90% confidence interval, -1.29%, was higher than the predefined noninferiority margin of -3%, the inferiority of the ventilation group over the deflation group was rejected at the .05 level of significance. Other complication rates and success rates of catheterization were comparable between 2 groups. The oxygen saturation dropped below 95% in 9 patients in the deflation group, while none in the ventilation group (P = .007). The success and complication rates were similar regardless of mechanical ventilation. During infraclavicular subclavian venous catheterization, interruption of mechanical ventilation does not seem to be necessary for the prevention of pneumothorax.

    A 42-year-old woman had bladder extrophy at birth, treated by ureterocolic anastomosis of her single kidney. She suffered recurrent hyperammonaemia, leading to comas, but refused an ileal conduit. During her most recent coma, it was decided to divert her urine to test whether this would reduce hyperammonaemia: this was accomplished by transcolonic retrograde catheterization of the ureter. This was only possible after computed tomography ureterography to show the ureterocolic anastomosis. Ureterocolic anastomosis is associated with several complications, the best known being hyperchloraemic acidosis and potassium deficiency. There is also a very high incidence of stricture at the anastomosis, both benign and malignant. Hyperammonaemia is less common. It can lead to disturbance of consciousness and seizures. It is caused by reabsorption of ammonia from the colon, exacerbated by the presence of urea-splitting organisms. Copyright (1999) Blackwell Science Pty Ltd 8 refs., 4 figs.

  19. Feasibility of the Use of Transesophageal Echocardiography as a Surface Probe for Puncturing and Catheterization of the Internal Jugular Vein: A Randomized Controlled Pilot Study. (United States)

    Teng, Yi; Ou, Mengchan; Yu, Hai


    To compare the transesophageal echocardiography (TEE) probe as a surface probe with the vascular probe for guiding internal jugular vein (IJV) catheterization. Prospective, randomized, controlled pilot study. University hospital. One hundred cardiac surgery patients, including 50 adult and 50 pediatric patients. Patients in the TEE probe group received right IJV catheterization using the TEE probe, while the vascular probe group used the vascular probe for catheterization. The puncture time, first-attempt success rate, quality of the imaging with needle tip positioning, wire positioning, and catheter positioning were recorded. The incidence of complication or any adverse event also was observed. Adult patients: In the vascular probe group, the success rate for first attempt IJV catheterization was 24/25 (96%), while in the TEE probe group, the success rate for first attempt IJV catheterization was 25/25 (100%). There was no statistical difference in the puncture time, image quality, needle tip positioning, wire positioning, and catheter positioning between groups (p > 0.05). Pediatric patients: The success rate for first-attempt IJV catheterization was 100% in both groups, and there were no statistical differences in the puncture time, image quality, and positioning between the 2 groups (p > 0.05). No complications or adverse events were observed in either group. The TEE probe, used as a surface probe, can be used to guide IJV puncturing and catheterization in cardiac surgery patients with favorable feasibility and safety. Copyright © 2017 Elsevier Inc.

  20. An Unusual Cause of Cardiac Tamponade during Cardiac Catheterization Study

    Directory of Open Access Journals (Sweden)

    Deepanwita Das


    Full Text Available Introduction. Catheter-based diagnostic and therapeutic procedures are rapidly advancing. However, catheter related complications sometimes become life threatening. Cardiac tamponade is a rare but serious complication of this procedure. We have summarized one cardiac tamponade pejoration due to secondary coronary vessels laceration by the implanted pericardial drainage. Case report. A 4-year-old baby having Tetralogy of Fallot was posted for diagnostic catheterization study. Patient was induced with sevoflurane and spontaneous respiration was maintained. After catheter insertion to RV, dye was injected through the catheter which rapidly spread into the pericardial cavity indicating right ventricle perforation. Immediately, blood was aspirated under transthoracic echocardiographic guidance and hemodynamics started improving. For the provision of quick access to aspirate further collection, an intrapericardial sheath was inserted after multiple attempts. Patient’s condition started deteriorating again. TTE revealed again some collection and it was increasing gradually. On exploration, it was found that there was continuous bleeding from a lacerated epicardial vessel which contributed to the pericardial collection leading to further tamponade effect. This second iatrogenic injury complicated the management of the first iatrogenic cardiac perforation and, thereby, created a life-threatening situation which needed immediate surgical exploration. Discussion. Usual cause of tamponade after right ventricular perforation is bleeding from the RV, but in our case the second tamponade was not due to bleeding from the RV, but was rather from new laceration injury of epicardial vessels which was remained undiagnosed till exploration.

  1. Ultrasound-guided central venous catheterization in prone position

    Directory of Open Access Journals (Sweden)

    Sofi Khalid


    Full Text Available Central venous catheterization (CVC is a commonly performed intraoperative procedure. Traditionally, CVC placement is performed blindly using anatomic landmarks as a guide to vessel position. Real-time ultrasound provides the operator the benefit of visualizing the target vein and the surrounding anatomic structures prior to and during the catheter insertion, thereby minimizing complications and increasing speed of placement. A 22-year-old male underwent open reduction and internal fixation of acetabulum fracture in prone position. Excessive continuous bleeding intraoperatively warranted placement of CVC in right internal jugular vein (IJV, which was not possible in prone position without the help of ultrasound. Best view of right IJV was obtained and CVC was placed using real-time ultrasound without complications. Ultrasound-guided CVC placement can be done in atypical patient positions where traditional anatomic landmark technique has no role. Use of ultrasound not only increases the speed of placement but also reduces complications known with the traditional blind technique.

    Skills trainings are increasing in popularity in undergraduate medical education enhancing clinical competencies and motivation for clinical practice. A suprapubic aspiration (SPA) is the gold standard to obtain urine from toddlers and young infants with fever and unclear focus to prove an urinary tract infection. In a blended-learning scenario with virtual patients and skills lab training students were trained for a SPA. Currently, no toddler simulation manikin for SPA is available on the market so we constructed one with simple means. Students' acceptance and their view on relevant aspects of the manikin for learning effectiveness were assessed. With an expenditure regarding work of 3½ h and material costs of 188.12 Euro we were able to construct a paediatric manikin for suprapubic bladder punction using a cheap basic life support manikin. N = 56 students rated their learning success with the manikin as high (77.2 ± 21.6; mean and standard deviation; visual analogue scales from 100 = totally agree to 0 = don't agree at all). The model was rated as useful for training (84.2 ± 17.2) and realistic (62.1 ± 23.5). Important factors for students' learning success were (in descending order) that "urine" could be aspirated (81.4 ± 19.5), the feel of the needle inserted in the manikin (71.5 ± 23.2), and--notably less important--the outer appearance in general (40.3 ± 24.6). We present a construction of a paediatric manikin for suprapubic aspiration with simple means for a realistic learning scenario with high learning success.

    Shahbaz Habib Faridi


    Full Text Available We encountered a 55-year-old man, who presented with an orifice in the suprapubic region, through which fecal material was discharged. On physical examination, the patient was unstable. After resuscitation, thorough evaluation, and laboratory and imaging investigations, he underwent an exploratory laparotomy. The ileum was entrapped at the deep inguinal ring, and there was some pus in the pelvic cavity. The purulent material was cleaned, and anastomosis was done after the resection of the defective ileal segment. In view of the rarity of this presentation and the paucity of published articles, this case is reported here.

  7. The Transradial Approach for Cardiac Catheterization and Percutaneous Coronary Intervention: A Review

    Directory of Open Access Journals (Sweden)

    Dhaval Pau, MD


    Full Text Available Cardiac catheterization and percutaneous coronary intervention play an important role in the management of coronary artery disease. Although the transfemoral approach has been the traditionally dominant method, there has been an increased utilization of the transradial approach. Multiple observational studies and randomized clinical trials have shown fewer bleeding complications, reduced morbidity and mortality, improved quality of life, and better economic outcomes when the transradial approach is utilized when compared to the transfemoral approach. Despite its many benefits, utilization of this approach in certain countries including the United States has been less than optimal due to a lower adoption rates mostly driven by lack of training opportunities and decreased awareness of clinical benefits of the transradial approach. In this review, the history, observational trends, efficacy, and technical aspects of transradial cardiac catheterization and percutaneous coronary intervention are discussed.

    To identify patients suitable for outpatient cardiac catheterization strategy, based on social aspects, risks and complications, for a 24 hour period. In a series of 2.126 cases submitted to cardiac catheterization at the Instituto Dante Pazzanese de Cardiologia, between September 1990 and June 1991, were excluded: a) those over 75 years of age; b) the acute ischemic syndromes; c) those in NYHA functional class IV; d) patients who used 7 or 8 French femoral angiographic catheters; e) patients who had undergone general anesthesia, electrophysiological study or endomyocardial biopsy. After the procedure, the patients were observed for a 3 hour period and in the absence of any complication, they were discharged from the hospital, returning the next day for clinical evaluation. If any complication occurred it was registered. In a cohort of 719 eligible patients, 68% were male, with a mean age of 55.3 years. Sixty one per cent were in NYHA functional class I and most of them (80.8%) were studied by the brachial approach. Eighty-three per cent of the patients were submitted to coronary angiography, with 52% of them having coronary artery disease. Four hundred and fourteen patients were not discharged on the same day: 217 did not have their procedures finish after 6 p.m., 111 for social-economical reasons, 23 because of their physician's refuse, 8 because of left main coronary disease, 55 because of any kind of complication. All the 305 patients who were discharged on the same day, did not have shown any complication in the next day evaluation. Outpatient cardiac catheterization is a safe technique in selected patients, making possible the accomplishment of a greater number of procedures improving bed utilization and decreasing hospital costs.

  9. Alternatives to Indwelling Catheters Cause Unintended Complications. (United States)

    Nguyen, Jessica; Harvey, Ellen M; Lollar, Daniel I; Bradburn, Eric H; Hamill, Mark E; Collier, Bryan R; Love, Katie M


    To reduce the risk of catheter-associated urinary tract infection (CAUTI), limiting use of indwelling catheters is encouraged with alternative collection methods and early removal. Adverse effects associated with such practices have not been described. We also determined if CAUTI preventative measures increase the risk of catheter-related complications. We hypothesized that there are complications associated with early removal of indwelling catheters. We described complications associated with indwelling catheterization and intermittent catheterization, and compared complication rates before and after policy updates changed catheterization practices. We performed retrospective cohort analysis of trauma patients admitted between August 1, 2009, and December 31, 2013 who required indwelling catheter. Associations between catheter days and adverse outcomes such as infection, bladder overdistention injury, recatheterization, urinary retention, and patients discharged with indwelling catheter were evaluated. The incidence of CAUTI and the total number of catheter days pre and post policy change were similar. The incidence rate of urinary retention and associated complications has increased since the policy changed. Practices intended to reduce the CAUTI rate are associated with unintended complications, such as urinary retention. Patient safety and quality improvement programs should monitor all complications associated with urinary catheterization practices, not just those that represent financial penalties.

    Kobayashi, Yo; Hong, Jaesung; Hamano, Ryutaro; Hashizume, Makoto; Okada, Kaoru; Fujie, Masakatsu G.

    Central venous catheterization is a procedure, which a doctor insert a catheter into the patient’s vein for transfusion. Since there are risks of bleeding from arterial puncture or pneumothorax from pleural puncture. Physicians are strictly required to make needle reach up into the vein and to stop the needle in the middle of vein. We proposed a robot system for assisting the venous puncture, which can relieve the difficulties in conventional procedure, and the risks of complication. This paper reports the design structuring and experimental results of needle insertion manipulator. First, we investigated the relationship between insertion force and angle into the vein. The results indicated that the judgment of perforation using the reaction force is possible in case where the needling angle is from 10 to 20 degree. The experiment to evaluate accuracy of the robot also revealed that it has beyond 0.5 mm accuracy. We also evaluated the positioning accuracy in the ultrasound images. The results displays that the accuracy is beyond 1.0 mm and it has enough for venous puncture. We also carried out the venous puncture experiment to the phantom and confirm our manipulator realized to make needle reach up into the vein.

  13. Comparative effectiveness and safety of a catheterization laboratory-only eptifibatide dosing strategy in patients undergoing percutaneous coronary intervention. (United States)

    Gurm, Hitinder S; Hosman, Carrie; Bates, Eric R; Share, David; Hansen, Ben B


    Eptifibatide, a small-molecule glycoprotein IIb/IIIa inhibitor, is conventionally administered as a bolus plus infusion. A growing number of clinicians are using a strategy of catheterization laboratory-only eptifibatide (an off-label use) as procedural pharmacotherapy for patients undergoing percutaneous coronary intervention although the comparative effectiveness of this approach is unknown. We compared the in-hospital outcome of patients undergoing percutaneous coronary intervention across 47 hospitals and treated with eptifibatide bolus plus infusion with those treated with a catheterization laboratory-only regimen. We used optimal matching to link the use of catheterization laboratory-only eptifibatide with clinical outcomes, including mortality, myocardial infarction, bleeding, and need for transfusion. Of the 84 678 percutaneous coronary interventions performed during 2010 to 2011, and meeting our inclusion criteria, eptifibatide was administered to 21 296 patients. Of these, a catheterization laboratory-only regimen was used in 4511 patients, whereas 16 785 patients were treated with bolus plus infusion. In the optimally matched analysis, compared with bolus plus infusion, a catheterization laboratory-only regimen was associated with a reduction in bleeding (optimally matched adjusted odds ratio, 0.74; 95% confidence interval, 0.58-0.93; P=0.014) and need for transfusion (optimally matched adjusted odds ratio, 0.70; 95% confidence interval, 0.52-0.92; P=0.012), with no difference in mortality or myocardial infarction. A catheterization laboratory-only eptifibatide regimen is commonly used in clinical practice and is associated with a significant reduction in bleeding complications in patients undergoing contemporary percutaneous coronary intervention. © 2015 American Heart Association, Inc.

    Full Text Available Background It is believed that healthcare staff play an important role in minimizing complications related to urethral catheterization. The purpose of this study was to determine whether or not healthcare staff complied with the standards for urethral catheterization. Methods This study was conducted in Imam Reza teaching hospital, Tabriz, Iran, from July to September 2013. A total of 109 catheterized patients were selected randomly from surgical and medical wards and intensive care units (ICUs. A questionnaire was completed by healthcare staff for each patient to assess quality of care provided for catheter insertion, while catheter in situ, draining and changing catheter bags. Items of the questionnaire were obtained from guidelines for the prevention of infection. Data analysis was performed with SPSS 16. Results The mean age of the patients was 50.54 ± 22.13. Of the 109 patients, 56.88% were admitted to ICUs. The mean duration of catheter use was 15.86 days. Among the 25 patients who had a urinalysis test documented in their hospital records, 11 were positive for urinary tract infection (UTI. The lowest rate of hand-washing was reported before bag drainage (49.52%. The closed drainage catheter system was not available at all. Among the cases who had a daily genital area cleansing, in 27.63% cases, the patients or their family members performed the washing. In 66.35% of cases, multiple-use lubricant gel was applied; single-use gel was not available. The rate of documentation for bag change was 79%. Conclusion The majority of the guideline statements was adhered to; however, some essential issues, such as hand hygiene were neglected. And some patients were catheterized routinely without proper indication. Limiting catheter use to mandatory situations and encouraging compliance with guidelines are recommended.

    Huang, Wei-lang; Wang, You-zhi; Lin, Xin; Liu, Biao


    To investigate the effect and safety of imaging-guided percutaneous catheterization drainage and alcohol sclerosis for treatment of renal cysts. Thirty-six patients with primary renal cysts, including 22 men and 14 women aged 18-65 years (mean 42.5 years), were treated with imaging-guided percutaneous puncture catheterization drainage and alcohol sclerosis treatment. The location of the renal cysts and puncture route, angle and depth were determined by ultrasound or CT scan. Paracentesis and catheterization external drainage were carried out under fluoroscope. Absolute alcohol was used as the sclerosis agent. Thirty-eight cysts were detected in the 36 patients, locating at the upper pole (n=21), subtus pole (n=10) and intermediate pole (n=7). The length of renal cysts was 4.5-8.5 cm (mean 5.5 cm). Puncture was performed through the lumbar back and the success rate was 100%. Thirty-eight multi-lateral holes 5-7F drainage catheters were placed in the 38 cysts. Alcohol was injected for 169 times through the drainage tube and the average volume was 25 ml, with an average injection of 4.45 times. During the follow-up for 1 to 6 years (mean 3.5 years), 37 renal cysts disappeared and 1 cyst was reduced in a patient with polycystic kidney. The total cure rate was 97% in this series, and no serious complications occurred after the operation. Imaging-guided percutaneous puncture catheterization drainage and alcohol sclerosis is effective and safe for treatment of renal cysts.

  16. Acute Aortic Dissection Mimicking STEMI in the Catheterization Laboratory: Early Recognition Is Mandatory

    Directory of Open Access Journals (Sweden)

    Alessio Arrivi


    Full Text Available Coronary malperfusion due to type A aortic dissection is a life-threatening condition where timely recognition and treatment are mandatory. A 77-year-old woman underwent an acute evolving type A aortic dissection mimicking acute myocardial infarction. Two pathophysiologic mechanisms are discussed: either thrombosis migrating from a previously treated giant aneurism of proximal left anterior descending or a local arterial complication due to left main stenting. Recognition of these occurrences in the catheterization laboratory is important to look immediately for surgery.

  17. Bluish Discolouration of Urine Drainage Tube and Bag in a Female Patient with Spina Bifida, Paraplegia, and Suprapubic Cystostomy

    Subramanian Vaidyanathan


    Full Text Available We present a female patient with spina bifida, paraplegia, suprapubic cystostomy, and chronic constipation, who became anxious when she noticed a bluish discolouration of her urine drainage system. Urine microbiology revealed growth of Providencia stuartii and Staphylococcus aureus. There were no systemic features of infection and, therefore, antibiotics were not prescribed for asymptomatic bacteriuria. This patient was advised to change the urine bag every day, and was prescribed senna to facilitate bowel evacuation. She was reassured that bluish discolouration of the urine drainage tube and bag was a transient, benign phenomenon and not indicative of any underlying pathology. Over the next 7 days, the bluish discolouration gradually faded away. Clinical characteristics of patients who are likely to develop this phenomenon and the underlying biochemical mechanism for bluish discolouration of the urine drainage system are discussed in brief.

    Introduction: Central venous catheter placement is an effective alternative vascular access for dialysis in patients with chronic renal failure. The purpose of this study was to evaluate the insertion of central venous catheters for hemodialysis using angiographic techniques in patients with previous multiple catheterizations in terms of efficacy of the procedure and early complications. Materials and methods: Between 2008 and 2010, the vascular access team of our hospital placed 409 central venous catheters in patients with chronic renal failure. The procedure was performed using the Seldinger blind technique. In 18 (4.4%) cases it was impossible to advance the guidewire, and so the patients were transported to the angiography suite. Results: Using the angiographic technique, the guidewire was advanced in order to position the central venous catheter. The latter was inserted into the subclavian vein in 12 (66.6%) cases, into the internal jugular vein in 4 (22.2%) and into the femoral vein in 2 (11.1%) cases. There was only one complicated case with severe arrhythmia in 1 (5.5%) patient. Conclusion: Our results suggest that insertion of central venous catheters using angiographic techniques in hemodialysis patients with previous multiple catheterizations is a safe and effective procedure with few complications and high success rates.

  19. Filmless multimedia display following cardiac catheterization. (United States)

    Mathewson, J W


    In traditional cardiac catheterization laboratories, anatomic images are acquired onto 35-mm cine film and presented in series with related information days, weeks, or months later to an audience of decision-makers. These data are projected onto a convenient light-colored wall or silver screen, while echocardiograms and electrophysiologic data are displayed using small single-user computer monitors. This presentation format is not ideal, because full audience participation is not fostered, image quality may be degraded, and small computer screens can be adequataly visualized only by those individuals immediately in front of them. Modern video multimedia systems now make an ideal data presentation format practical, in which all types of media including digitally acquired angiograms can be displayed in parallel with full annotation, using large diagonal multisync color monitors. This communication discusses how to design a multimedia conference center in which remotely acquired filmless digital images can be displayed and processed together with all other pertinent cardiac multimedia to a large audience.

  20. [Patient's consent to central venous catheterization]. (United States)

    Fiorini, F; Palumbo, G; Ciliberti, R


    The need to obtain a patient's consent for his health care is a principle set out in the Italian Constitution, which safeguards a person's right to health. Articles 13 and 32.2 confirm a person's freedom and the right to make free decisions about one's medical treatment. Nobody must be obliged to any medical procedure, unless as by law enacted. The obligation to inform patients is important during the contractual phase: consent is an essential element in the professional contract governing the relationship between a physician and a patient. The former is obligated to inform the latter about his medical intervention clearly and precisely, to enable the patient to decide freely whether to undergo a medical procedure. At this point, it is also essential to obtain a patient's consent for those treatments that although they are carried out in a correct and careful way, could damage a person's physical integrity. The failure to obtain consent could give rise to a burden of responsibility on behalf of the clinician. A central venous catheterization in hemodialysis (HD) is a common procedure performed during routine nephrological treatments. Our signed informed consent form prior to introducing a central venous catheter is thought to satisfy requirements provided for in current regulations to give correct information.

  1. Effective anxiety treatment prior to diagnostic cardiac catheterization. (United States)

    McCaffrey, Ruth; Taylor, Natalie


    Music therapy, massage, guided imagery, therapeutic touch, and stress management instruction have been used successfully to decrease patient anxiety prior to diagnostic cardiac catheterization, providing better patient outcomes. The anxiety experienced among patients may have various causes, including not feeling cared about as an individual, too much waiting time before the procedure begins, and physical discomfort. This review determines nursing interventions that may effectively reduce anxiety prior to diagnostic cardiac catheterization.

    Rogers, Toby; Ratnayaka, Kanishka; Khan, Jaffar M; Stine, Annette; Schenke, William H; Grant, Laurie P; Mazal, Jonathan R; Grant, Elena K; Campbell-Washburn, Adrienne; Hansen, Michael S; Ramasawmy, Rajiv; Herzka, Daniel A; Xue, Hui; Kellman, Peter; Faranesh, Anthony Z; Lederman, Robert J


    Quantification of cardiac output and pulmonary vascular resistance (PVR) are critical components of invasive hemodynamic assessment, and can be measured concurrently with pressures using phase contrast CMR flow during real-time CMR guided cardiac catheterization. One hundred two consecutive patients underwent CMR fluoroscopy guided right heart catheterization (RHC) with simultaneous measurement of pressure, cardiac output and pulmonary vascular resistance using CMR flow and the Fick principle for comparison. Procedural success, catheterization time and adverse events were prospectively collected. RHC was successfully completed in 97/102 (95.1%) patients without complication. Catheterization time was 20 ± 11 min. In patients with and without pulmonary hypertension, baseline mean pulmonary artery pressure was 39 ± 12 mmHg vs. 18 ± 4 mmHg (p < 0.001), right ventricular (RV) end diastolic volume was 104 ± 64 vs. 74 ± 24 (p = 0.02), and RV end-systolic volume was 49 ± 30 vs. 31 ± 13 (p = 0.004) respectively. 103 paired cardiac output and 99 paired PVR calculations across multiple conditions were analyzed. At baseline, the bias between cardiac output by CMR and Fick was 5.9% with limits of agreement -38.3% and 50.2% with r = 0.81 (p < 0.001). The bias between PVR by CMR and Fick was -0.02 WU.m 2 with limits of agreement -2.6 and 2.5 WU.m 2 with r = 0.98 (p < 0.001). Correlation coefficients were lower and limits of agreement wider during physiological provocation with inhaled 100% oxygen and 40 ppm nitric oxide. CMR fluoroscopy guided cardiac catheterization is safe, with acceptable procedure times and high procedural success rate. Cardiac output and PVR measurements using CMR flow correlated well with the Fick at baseline and are likely more accurate during physiological provocation with supplemental high-concentration inhaled oxygen.

  3. Jugular Venous Catheterization: A Case of Knotting

    Directory of Open Access Journals (Sweden)

    E. Erkılıç


    Full Text Available A 79-year-old woman, diagnosed for cancer of the ovary, had a central catheter that was placed with difficulty through the right internal jugular vein intraoperatively. After oophorectomy, it was realized that the catheter was knotted. Thus, the central venous catheter was removed successfully using a traction technique in the operating room. Central venous catheter use may result in various complications, although it has been used as an invasive method for hemodynamic monitoring and fluid and drug infusion. Here, we present catheter knotting in a case with solutions for this complication, under literature review.

    Full Text Available Background: Although some investigations have shown higher rates of successful first attempt and fewer attempts by using ultrasound-guided Internal Jugular Vein (IJV catheterization, arterial puncture is still common.. Objectives: The present study aimed to investigate US-guided catheterization of the right IJV via medial-oblique technique and also compare this technique to short-axis technique in open-heart surgery patients.. Patients and Methods: In this randomized clinical trial, 80 patients referred to cardiac operating room of Namazi hospital, Shiraz, Iran from March to July 2014 were selected using census method. Block randomization with website was also done. Then, the patients were divided into two groups of 40, Short Axis Group (SAG and Medial-Oblique Group (M-OG. For short-axis technique, patient’s head was positioned at zero degree angulation with his trunk. For medial-oblique technique, on the other hand, patient’s head was tilted to left to 45 degrees between the head and trunk. Sex, age, Body Mass Index (BMI, access time, guidewire time, cannulation time, total attempts for catheterization, first, second, and third attempt success, arterial puncture, hematoma, bleeding, and catheter malposition were recorded. The overlap between the carotid artery and IJV in zero- and 45-degree angulation was estimated through ultrasound print. After all, Kolmogorov-Smirnov test was used to assess normal distribution of the data. Then, the data were analyzed through Student’s t-test, Mann-Whitney U test, and chi-square test. P < 0.05 was considered as statistically significant.. Results: The results showed no significant differences between the two groups regarding the duration of different catheterization steps (P = 0.376. In all the cases in both groups, accessing the vein was successful with three attempts or less. There were no clinical complications of catheterization in the two groups. The mean of overlap was 23.60 ± 33.47 in zero

[Department of Diagnostic and Interventional Radiology, Patras University Hospital, School of Medicine, Patras (Greece)


    Aim: To present the results of a prospective, randomized, single-centre study investigating local anaesthesia before percutaneous common femoral artery (CFA) puncture and catheterization with the use of ultrasound-guided injection of lidocaine versus standard infiltration by manual palpation. Materials and methods: Patients scheduled to undergo diagnostic or therapeutic transfemoral catheter-based procedures gave informed consent and were randomized in two groups. In the first arm local anaesthesia with lidocaine hydrochloride 1% was performed under ultrasound guidance (group U/S), while in the second arm the standard method of manual artery palpation was applied (group M). In both groups, subsequent CFA catheterization was achieved under ultrasound guidance. The primary study endpoint was peri-procedural pain level evaluated with a visual-analogue scale (VAS score 0-10). Results: Between January 2009 and 2010, 200 patients (161 men, mean age 63 {+-} 12 years) were equally assigned to each group without any significant differences in baseline demographics. Patients in group U/S experienced significantly less pain during CFA catheterization in comparison with group M with a difference of three points in mean VAS score reported (1.6 {+-} 1.6 versus 4.6 {+-} 1.9, p < 0.0001). In addition, significantly less volume of lidocaine was used in group U/S compared to group M (16 {+-} 2.7 versus 19 {+-} 0.8 ml, p < 0.001).Total vascular access time was similar in both groups (4.4 {+-} 1.3 versus 4.5 {+-} 1.3 min). Overall complications included two small groin haematomas in each group. Conclusion: Ultrasound-guided local anaesthesia of the CFA prior to percutaneous transcatheter procedures is safe and achieves superior levels of analgesia with minimal patient pain and discomfort compared to the standard method of manual palpation.

    Nearly 4 million patient procedures performed annually in US cardiac catheterization laboratories utilize contrast media to achieve vessel opacification. The amount of contrast media used is variable and depends on the complexity of the procedure, the method of contrast delivery as well as the skill-level of the operator. Since the total amount of contrast used for each procedure can have both patient safety and economic implications, it is essential for cardiologists to have the ability to control contrast delivery such that optimal angiographic image quality is achieved using the least amount of contrast. Although the complication rate associated with cardiac catheterization remains low, the most common serious complication, contrast-induced nephropathy (CIN), is associated with poor prognosis and a high mortality rate. Numerous interventional strategies for preventing and reducing the severity of CIN have demonstrated varying degrees of clinical benefit, but none has been shown to reliably prevent this serious complication. To date, the most effective approach for reducing the risk of CIN is to properly hydrate the patient and to minimize the amount of contrast media administered. Automated injection systems are intended for use in virtually all cardiac catheterization procedures and have numerous features which can provide potential advantages over traditional methods. With automated injection technology the operator is able to control and precisely monitor contrast delivery. Additionally, the MEDRAD Avanta Fluid Management Injection System utilizes a sterile contrast reservoir which eliminates the need to discard unused contrast in individual opened containers following each procedure. Considering that an average of 50% of opened contrast media is wasted using manual injection methods, this savings can provide a substantial economic benefit. Automated systems also facilitate the use of smaller (5 French) catheter sizes. Precise flow control and the use of

    PurposeThe purpose of the study was to retrospectively evaluate the efficacy and safety of the balloon blocking technique (BBT).Materials and MethodsThe BBT was performed in six patients (all males, mean 73.5 years) in whom superselective catheterization for transcatheter arterial embolization by the conventional microcatheter techniques had failed due to anatomical difficulty, including targeted arteries originating steeply or hooked from parent arteries. All BBT procedures were performed using Seldinger’s transfemoral method. Occlusive balloons were deployed and inflated at the distal side of the target artery branching site in the parent artery via transfemoral access. A microcatheter was delivered from a 5-F catheter via another femoral access and was advanced over the microguidewire into the target artery, under balloon blockage of advancement of the microguidewire into non-target branches. After the balloon catheter was deflated and withdrawn, optimal interventions were performed through the microcatheter.ResultsAfter success of accessing the targeted artery by BBT, optimal interventions were accomplished in all patients with no complications other than vasovagal hypotension, which responded to nominal therapy.ConclusionThe BBT may be useful in superselective catheterization of inaccessible arteries due to anatomical difficulties.

    Shahid M Khan


    Full Text Available Background: We report a diagnostic dilemma in a rare case of cerebral contrast retention after difficult cardiac catheterization in an elderly patient loaded with prasugrel. Summary: Our case report describes a 77-year-old female with history of hypertension, diabetes, and dyslipidemia who presented to emergency department complaining of chest pain. Patient was found to have an inferior wall ST elevation myocardial infarction. The patient was loaded with aspirin and prasugrel and taken for emergent cardiac catheterization. Cardiac catheterization revealed two-vessel coronary artery disease with unsuccessful attempt of percutaneous intervention. Immediately after procedure, patient developed an episode of seizure. Emergent computed tomography scan of the brain revealed hyperdensity in the right frontoparietal region consistent with intracerebral bleed. Repeat computed tomography (24 h later revealed substantial interval improvement of hyperdensity. Follow-up magnetic resonance imaging of the head was normal. Given the lack of magnetic resonance imaging changes, the rate of resolution on computed tomography without expected subacute changes, and the lack of neurologic findings, the initial hyperdensity seen on computed tomography of the brain was believed to be secondary to contrast leakage during cardiac catheterization as opposed to intracranial hemorrhage.

    Full Text Available The purpose of this study is to compare the rates of urinary tract infection (UTI and postoperative urinary retention (POUR in patients undergoing lower limb arthroplasty after either indwelling urinary catheterization or intermittent urinary catheterization.We conducted a meta-analysis of relevant randomized controlled trials (RCT to compare the rates of UTI and POUR in patients undergoing total joint arthroplasty after either indwelling urinary catheterization or intermittent urinary catheterization. A comprehensive search was carried out to identify RCTs. Study-specific risk ratios (RR with 95% confidence intervals (CI were pooled. Additionally, a meta-regression analysis, as well as a sensitivity analysis, was performed to evaluate the heterogeneity.Nine RCTs with 1771 patients were included in this meta-analysis. The results showed that there was no significant difference in the rate of UTIs between indwelling catheterization and intermittent catheterization groups (P>0.05. Moreover, indwelling catheterization reduced the risk of POUR, versus intermittent catheterization, in total joint surgery (P<0.01.Based on the results of the meta-analysis, indwelling urinary catheterization, removed 24-48 h postoperatively, was superior to intermittent catheterization in preventing POUR. Furthermore, indwelling urinary catheterization with removal 24 to 48 hours postoperatively did not increase the risk of UTI. In patients with multiple risk factors for POUR undergoing total joint arthroplasty of lower limb, the preferred option should be indwelling urinary catheterization removed 24-48 h postoperatively.Level I.

    A "learning health care system", as outlined in a recent Institute of Medicine report, harnesses real-time clinical data to continuously measure and improve clinical care. However, most current efforts to understand and improve the quality of care rely on retrospective chart abstractions complied long after the provision of clinical care. To align more closely with the goals of a learning health care system, we present the novel design and initial results of the Veterans Affairs (VA) Clinical Assessment, Reporting, and Tracking (CART) program-a national clinical quality program for VA cardiac catheterization laboratories that harnesses real-time clinical data to support clinical care and quality-monitoring efforts. Integrated within the VA electronic health record, the CART program uses a specialized software platform to collect real-time patient and procedural data for all VA patients undergoing coronary procedures in VA catheterization laboratories. The program began in 2005 and currently contains data on 434,967 catheterization laboratory procedures, including 272,097 coronary angiograms and 86,481 percutaneous coronary interventions, performed by 801 clinicians on 246,967 patients. We present the initial data from the CART program and describe 3 quality-monitoring programs that use its unique characteristics-procedural and complications feedback to individual labs, coronary device surveillance, and major adverse event peer review. The VA CART program is a novel approach to electronic health record design that supports clinical care, quality, and safety in VA catheterization laboratories. Its approach holds promise in achieving the goals of a learning health care system. Published by Elsevier Inc.

    To explore the safety and efficiency of transurethral plasmakinetic enucleation of prostate (TUPKEP) and suprapubic small cut in the treatment of high-risk and senior patients with benign prostatic hyperplasia and bladder stones. A retrospective review was conducted for 68 high-risk and senior patients with benign prostatic hyperplasia and bladder stones. All of them were treated by TUPKEP and suprapubic small cut. Operation was successfully performed in all 68 cases. And there was no instance of transurethral resection syndrome, shock, myocardial infarct, cerebral infarction, cerebral hemorrhage, permanent urinary incontinence or surgical site infection. Seven patients with temporal urinary incontinence recovered at a mean time of (9.48 ± 1.52) days post-operation. The mean operative duration was (48.63 ± 4.14) min and the mean volume of blood loss (50.97 ± 5.33) ml. The changes of maximum flow rate (Qmax), international prostatic symptom score (I-PSS) and quality-of-life (QOL) were statistically significant before and after operation. Qmax increased from (4.56 ± 0.35) to (18.82 ± 1.65) ml/s (P < 0.001), I-PSS decreased form (21.96 ± 1.89) to (11.23 ± 0.86) (P = 0.018) and QOL decreased from (4.94 ± 0.35) to (1.95 ± 0.32) (P = 0.011). The approach of TUPKEP and suprapubic small cut is both safe and effective in the treatment of high-risk and senior patient with benign prostatic hyperplasia and bladder stones and should be widely applied.

  19. 5-Fr sheathless transradial cardiac catheterization using conventional catheters and balloon assisted tracking; a new approach to downsizing. (United States)

    Mamas, Mamas A; George, Sudhakar; Ratib, Karim; Kwok, Chun Shing; Elkhazin, Abdelnasir; Sandhu, Kully; Stubbs, Julie; Luxford, Pamela; Nolan, James

    While the uptake of transradial access site is growing, there are concerns about associated radial injury. We report a feasibility study of a technique that enables both 5Fr diagnostic and PCI cases to be undertaken without an arterial sheath using conventional diagnostic and guide catheters with a modified balloon assisted tracking (BAT) technique. We performed a prospective single center pilot study to assess the feasibility and effectiveness of sheathless radial artery access and BAT to perform coronary angiography and angioplasty using conventional 5 Fr diagnostic and guide catheters. We assessed for successful acquisition of good quality angiogram, completion of the angioplasty and access site complications. 5 Fr sheathless cardiac catheterization was undertaken in diagnostic (55%) and PCI cases (45%, all indications) in 60 consecutive patients (mean age 62.8±11.4years) using conventional catheters. The procedure was successfully performed via the radial artery using a sheathless technique with BAT in 93.3% of patients. All patients had a patent radial artery following removal of the Helix device and there were no recorded access site complications. Trans-radial cardiac catheterisation for diagnostic and PCI cases using 5F Sheathless catheters (whose outer diameter is smaller than a 3Fr introducer sheath) with BAT appears feasible and allows both cardiac catheterization for diagnostic and PCI indications to be undertaken safely using conventional catheters through the radial route, with high success rates.

  20. Development of an education program on postcardiac catheterization care for ambulatory care nurses. (United States)

    Harper, John P


    One of the responsibilities of clinical educators is to identify learning needs of staff and to develop education programs to meet those needs. A new outpatient diagnostic cardiac catheterization program required patients to be transferred postprocedure to the short procedure unit until discharge. The author describes the development, the implementation, and the evaluation of an education program on postcardiac catheterization care for ambulatory care nurses as well as initiation of a new care program postcardiac catheterization.

    We wanted to introduce a new technique for superselective catheterization of arteries with preshaping of a micro-guide wire into a shepherd's hook form, and this is useful for superselection of small arteries branching at an acute angle from a large parent artery for the treatment of tumors and hemorrhages. We developed a superselective catheterization technique by using preshaping of a micro-guide wire into a shepherd's hook form. We encountered six patients in our practice for whom we failed to catheterize the small tumor-feeding arteries that branched at an acute angle from wide parent arteries during chemoembolization of hepatocellular carcinoma; the parent arteries were the right inferior phrenic artery (n = 4) and the left gastric artery (n = 1) from the celiac axis with celiac stenosis due to compression by the median arcuate ligament and the proper hepatic artery from the gastroduodenal artery (n = 1) in a patient who had celiac axis occlusion with collateral circulation via the pancreaticoduodenal arcade from the superior mesenteric artery. In these consecutive six patients, we tested the usefulness of this new technique with employing preshaping of a micro-guide wire into a shepherd's hook form for superselective catheterization of targeted vessels. The target arteries were successfully catheterized and satisfactory transcatheter arterial chemoembolization was performed in all six patients. There were no significant complications such as arterial dissection. We developed a technique that is effective for superselection of vessels with preshaping of micro-guide wire into a shepherd's hook hook form, and we successfully applied it during chemoembolization of hepatocellular carcinoma. This technique can be useful for superselection of small arteries that branch from a large parent artery at acute angles for the treatment of tumors and hemorrhages.

    Granel, F; Barbaud, A; Gillet-Terver, M N; Reichert, S; Weber, M; Danchin, N; Schmutz, J L


    Fluoroscopic and cineradiographic procedures expose patients undergoing coronarography to high doses of ionizing irradiation. We report four cases of radiodermitis following cardiac catheterization. A 69-year-old man developed a radio-induced ulceration on the left scapular region in 1991 which required excision with skin graft. He had undergone 3 coronarographies and 2 angioplasties from 1989 to 1991. In 1992, a 59-year-old women developed a hard dorsal lesion with central ulceration and scar formation requiring excision and graft. From 1990 to 1992, she had undergone two coronary dilatations with angioplasty during one procedure. An atrophic necrotic wound situated under the right nipple developed in a 63 year old man. Excision with flap reconstruction was performed in 1993, two years after an unsuccessful angioplasty then two-vessel bypass. In a fourth case, a 52 year-old woman developed a telangiectasic ulceration on the right breast in 1990. The diagnosis of radio-induced dermitis was confirmed in 1996 and the patient was treated by excision. She had had three angioplasties in 1989. Four other cases of radio-induced dermatitis following cardiac catheterism have been reported in the literature since 1996. Six other cases were also recently reported in France. All of these patients had undergone coronarography with transluminal coronary angioplasty. Besides coronarography, irradiation exposure is greatest for guide and balloon insertion required for dilatation procedures. Angioplasty is particularly dangerous because the irradiation beam is focused on the stenosis while the entire coronary network is concerned for coronarography. In most cases of radio-induced dermatitis following cardiac catheterism, the diagnosis is usually evident from the clinical context and the localization of the coronary lesion. In many cases however, the long delay to onset may make diagnosis a difficult task. In addition, the radiation dose delivered to the skin during cardiac

    This study examined the psychophysiologic responses of invasive cardiologists during cardiac catheterizations. Because occupations are most stressful when one is not in control, the effect of a teaching versus an autonomous role on the psychophysiologic response of invasive cardiologists was investigated. The subjects were 9 invasive cardiologists. Psychophysiologic variables such as state anxiety and salivary cortisol levels were measured before and after each invasive cardiologist performed 7 cardiac catheterizations. Heart rate was measured before, during, and after procedures. Three procedures were studied while invasive cardiologists were in the primary operator (autonomous) role with full responsibility and control, whereas 4 were studied while the subjects were in the secondary assistant (teaching) role with full responsibility and no control. There were no significant differences in physiologic arousal (heart rate and salivary cortisol levels) between catheterizations performed in the autonomous role versus those in the teaching role. However, the perceived anxiety scores were higher when in the teaching role versus when in the autonomous role. There were significant differences in psychophysiologic measurements of stress between less experienced cardiologists (out of training 5 years). Less experienced invasive cardiologists had significantly higher trait anxiety (38.4 vs 31.7, P = .001), baseline salivary cortisol levels (0.51 vs 0.33, P = .01), and heart rate change (50.1 vs 27.4 beats/min, P = .001) during procedures compared with more experienced cardiologists. Although there were no overall differences in the physiologic response to the autonomous and teaching roles, there was a higher perceived state of anxiety when in the teaching role. Less experienced invasive cardiologists had higher psychophysiologic measurements of stress during invasive procedures than did more experienced cardiologists.

    Little is known regarding alterations of the renin-angiotensin system in patients referred for cardiac catheterization. Here, we measured plasma levels of active renin and aldosterone in patients referred for cardiac catheterization in order to determine the prevalence of elevated renin, aldosterone, and the aldosterone-renin ratio.A chemiluminescence assay was used to measure plasma aldosterone concentration (PAC) and active renin levels in 833 consecutive patients, after an overnight fasting and without any medication for least 12 hours. We evaluated associations of the hormonal elevations in relation to hypertension, atrial fibrillation (AF), hypertensive cardiomyopathy, coronary artery disease (CAD), valvular disease, impaired left ventricular ejection fraction (LVEF 25 mm Hg).Hyperaldosteronism occurred in around one-third of all examined patients, without significant differences between patients with or without the named cardiac diseases. In a comparison between patients with or without any given cardiac disease condition, renin was significantly elevated in patients with either hypertension (36.4% vs 15.9%), CAD (33.9% vs 22.1%), or impaired LVEF (47.3% vs 24.8%). The angiotensin-renin ratio was elevated in AF patients and in patients with hypertensive cardiomyopathy. Patients with AF and coexisting hypertension had elevated renin more frequently than AF patients without coexisting hypertension (35.3% vs 16.5%; P  =  .005). Patients with persistent/permanent AF more frequently had elevated renin than patients with paroxysmal AF (34.1% vs 15.8%; P  =  .007).This prospective study of consecutive cardiac disease patients referred for cardiac catheterization has revealed distinct cardiac disease condition-associated differences in the frequencies of elevations in plasma renin, PAC, and the aldosterone-renin ratio.

    Knot formation in the distal segment of an angiographic catheter is not very frequent. Its early recognition, as well as domination of several techniques in order to untie it, may avoid surgery. An unique technique in order to untie a knot in a catheter is described, which consists in using other more rigid catheter with "J" shaped end by contralateral femoral via and under direct fluoroscopic visualization, with image magnifier and fitted TV.

    Full Text Available Introduction: Central venous catheterization (CVC can be an important component of the management of patients with severe sepsis and septic shock. CVC, however, is a time- and resource-intensive procedure associated with serious complications. The effects of the absence of shock or the presence of relative contraindications on undertaking central line placement in septic emergency department (ED patients eligible for early goal-directed therapy (EGDT have not been well described. We sought to determine the association of relative normotension (sustained systolic blood pressure >90 mmHg independent of or in response to an initial crystalloid resuscitation of 20 mL/kg, obesity (body mass index [BMI] ≥30, moderate thrombocytopenia (platelet count <50,000 per μL, and coagulopathy (international normalized ratio ≥2.0 with unattempted CVC in EGDT-eligible patients. Methods: This was a retrospective cohort study of 421 adults who met EGDT criteria in 5 community EDs over a period of 13 months. We compared patients with attempted thoracic (internal jugular or subclavian CVC with those who did not undergo an attempted thoracic line. We also compared patients with any attempted CVC (either thoracic or femoral with those who did not undergo any attempted central line. We used multivariate logistic regression analysis to calculate adjusted odd ratios (AORs. Results: In our study, 364 (86.5% patients underwent attempted thoracic CVC and 57 (13.5% did not. Relative normotension was significantly associated with unattempted thoracic CVC (AOR 2.6 95% confidence interval [CI], 1.6-4.3, as were moderate thrombocytopenia (AOR 3.9; 95% CI, 1.5-10.1 and coagulopathy (AOR 2.7; 95% CI, 1.3-5.6. When assessing for attempted catheterization of any central venous site (thoracic or femoral, 382 (90.7% patients underwent attempted catheterization and 39 (9.3% patients did not.

    Chih-Jou Lai


    Full Text Available Complex regional pain syndrome (CRPS is a disease with unclear pathophysiology. The condition is characterized by pain, soft tissue change, vasomotor change, and even psychosocial disturbance. It may affect the upper more than the lower extremities, and the distal more than the proximal. The trigger factors include carpal tunnel release, Dupuytren's repair, tendon release procedures, knee surgery, crush injury, ankle arthrodesis, amputation, and hip arthroplasty. Rarely, it has been associated with stroke, mastectomy, pregnancy, and osteogenesis imperfecta. Herein, we present a rare case of a patient who was diagnosed with CRPS after transradial cardiac catheterization. CRPS was first diagnosed due to hand swelling, allodynia, paresthesia, and the limited range of motion of interphalangeal, metacarpophalangeal, and wrist joints, with the preceding factor of transradial cardiac catheterization, and was then confirmed by a three-phase bone scan. After intensive physical therapy with hydrotherapy, manual soft tissue release, and occupational therapy for the hand function, there was much improvement in range of motion and hand function. There was no allodynia or painful sensation in the follow-up. After training, the functional status of this patient was adequate for daily activity.

  9. Urinary catheterization of male rabbits: a new technique and a review of urogenital anatomy. (United States)

    Uthamanthil, Rajesh K; Hachem, Ray Y; Gagea, Mihai; Reitzel, Ruth A; Borne, Agatha T; Tinkey, Peggy T


    Rabbits are widely used as an animal model for urologic research studies in which urinary bladder catheterization is required. However, standard manual retrograde urinary catheterization proved to be difficult to perform on anesthetized male rabbits in a research study, with frequent misplacement of the catheter into the vesicular gland. Attempts to reposition the catheter into the bladder after initial entry into the vesicular gland frequently failed and resulted in exclusion of the animal from the study. We assessed the normal anatomy of the lower urinary tract of male rabbits to determine the cause of catheterization misdirection into the vesicular gland and to develop a more reliable technique for urinary bladder catheterization. A modified 'digital (finger) pressure' catheterization technique was developed for successful urinary catheterization of male rabbits. Retrospective statistical analysis of 45 rabbits used for urinary catheterization studies showed improvement in the success rate of catheterization by using the digital pressure technique over the standard method of retrograde urinary catheter insertion. In addition, we here review the relevant gross and histologic anatomy of the urogenital tract of male rabbits.

    P. Kumar


    Full Text Available INTRODUCTION: We aimed to investigate the rate of urinary retention after knee arthroplasty, the various factors involved in predicting those at risk for retention and to assess the impact of retention and catheterization on joint sepsis. MATERIALS AND METHODS: A retrospective review was conducted of all available case notes of patients undergoing total knee arthroplasty in a consecutive 2-year period (2000-2002. Adequate data was available for 142 patients. RESULTS: 142 patients underwent total knee arthroplasty. 19 patients were catheterized preoperatively for monitoring urine output. 123 patients were not catheterized. Urinary retention occurred in 19.7% (28/142. The mean day of catheterization for retention was 0.66. The mean duration of catheterization in patients developing retention was 3.58 days and was 3 days in the patients catheterized pre - or perioperatively. Deep joint sepsis occurred in 2.1% (3/142 - only one had been catheterized and that was preoperatively. No case of infection had urinary retention or had a symptomatic urinary tract infection. The only factors predicting those at significant risk of retention following knee arthroplasty was a past medical history of urinary retention (p = 0.049 and postoperative morphine requirement (p = 0.035. No patients required urological surgical intervention at mean follow up of 1.97 years. CONCLUSIONS: This study supports the use of indwelling urinary catheterization for patients developing urinary retention after total knee arthroplasty.

  12. Transient left bundle branch block induced by left-sided cardiac catheterization in patients without pre-existing conduction abnormalities. (United States)

    Shimamoto, T; Nakata, Y; Sumiyoshi, M; Ogura, S; Takaya, J; Sakurai, H; Yamaguchi, H


    A traumatic left bundle branch block (LBBB) is uncommon in a patient with intact atrioventricular conduction. Three of our patients developed LBBB during a left-sided catheterization. Two patients suffered from angina pectoris and the other had an abdominal aneurysm. Two of them had a history of hypertension. None of the patients had ever shown any conduction abnormalities before the catheterization. The electrocardiogram just before the examination was normal in all 3 patients. LBBB was observed when a catheter was introduced into the left ventricle, and lasted 2--4 min without significant change in heart rates. Examination revealed no significant stenosis proximal to the first septal perforator and normal left ventricular contraction in all patients. One patient developed permanent LBBB 14 months later. Catheter-induced LBBB may occur easily with certain anatomical characteristics of the left bundle branch or the distal His bundle, with or without some concealed damage to the conduction system. It is important to keep this complication in mind and to pay adequate attention to patients' electrocardiograms as well as their angiographical findings, especially in those with pre-existing right bundle branch block.

  14. Reengineering the Cardiac Catheterization Lab Processes: A Lean Approach

    Directory of Open Access Journals (Sweden)

    Venkatesh Raghavan


    Full Text Available This paper presents a cross-functional effort in a US community hospital for an overall process improvement in its Cardiac Catheterization Lab (CCL. One of the key system performance metrics identified was the patient turnaround time. The objective of this study was to identify the sources of delays in the system that lead to prolonged patient turnaround time using a structured lean approach. A set of qualitative recommendations were proposed and implemented. Quantification of some of these recommendations and certain additional ‘what-if’ scenarios were evaluated using Discrete Event Simulation (DES. The simulation results showed that significant reduction in patient turnaround time could be achieved if the proposed recommendations were implemented. This study demonstrated the benefits of adopting the lean philosophy in the continuous process improvement journey in the healthcare delivery arena.

  15. Radiation Dose Estimation for Pediatric Patients Undergoing Cardiac Catheterization (United States)

    Wang, Chu

    Patients undergoing cardiac catheterization are potentially at risk of radiation-induced health effects from the interventional fluoroscopic X-ray imaging used throughout the clinical procedure. The amount of radiation exposure is highly dependent on the complexity of the procedure and the level of optimization in imaging parameters applied by the clinician. For cardiac catheterization, patient radiation dosimetry, for key organs as well as whole-body effective, is challenging due to the lack of fixed imaging protocols, unlike other common X-ray based imaging modalities. Pediatric patients are at a greater risk compared to adults due to their greater cellular radio-sensitivities as well as longer remaining life-expectancy following the radiation exposure. In terms of radiation dosimetry, they are often more challenging due to greater variation in body size, which often triggers a wider range of imaging parameters in modern imaging systems with automatic dose rate modulation. The overall objective of this dissertation was to develop a comprehensive method of radiation dose estimation for pediatric patients undergoing cardiac catheterization. In this dissertation, the research is divided into two main parts: the Physics Component and the Clinical Component. A proof-of-principle study focused on two patient age groups (Newborn and Five-year-old), one popular biplane imaging system, and the clinical practice of two pediatric cardiologists at one large academic medical center. The Physics Component includes experiments relevant to the physical measurement of patient organ dose using high-sensitivity MOSFET dosimeters placed in anthropomorphic pediatric phantoms. First, the three-dimensional angular dependence of MOSFET detectors in scatter medium under fluoroscopic irradiation was characterized. A custom-made spherical scatter phantom was used to measure response variations in three-dimensional angular orientations. The results were to be used as angular dependence

    Full Text Available Objective: The objective of this story of case is to describe an uncommon cause of associated peripheral Vestibulopathy to the unilateral auditory loss in aged patient after catheterization of urgency. Story of case: Patient of the masculine sort, 82 years, submitted to the correction of abdominal ragged aneurism of aorta, in the intra-operative suffered heart attack acute from the myocardium needing primary angioplasty. High after hospital it relates to complaint of accented hearing loss to the right and crippling vertigo, without focal neurological signals. To the otorhinolaryngological clinical examination it presented: Test of Weber lateralized for the left, spontaneous nystagmus for the left, marches rocking, has taken normal disbasia and ataxia, index-nose and diadochokinesia, Test of Romberg with oscillation without fall and Fukuda with lateral shunting line for the right. The audiometric examination evidenced deafness to the right and sensorineural loss to the left in sharps, areflexia initial to the right in caloric test e, the computerized tomography of the secular bones and brainstem, presence of metallic connecting rod crossing the right secular bone, from the vein internal jugular vein and bulb jugular vein, crossing the posterior, superior and vestibule semicircular canals, projecting itself in temporal lobe. The radiological diagnoses was traumatic injury for guide to endovascular metallic during catheterization of urgency and the behavior, considering that the patient had not compensated the balance, it was vestibular rehabilitation. Conclusion: Complaints of giddiness in the aged patient must be closely evaluated of its pathological clinical description because the antecedents of illnesses and previous treatments, in general, direct the diagnostic hypotheses however they can bring unexpected alterations.

    disease (48.3%). In the 27 191 patients undergoing PCI, 367 treated lesions (1.3%) were in the left main artery and 3831 (13.8%) in the proximal left anterior descending artery. A total of 11 366 patients (40.8%) received drug-eluting stents. Complications occurred in a few patients, with a catheterization-related mortality rate of 0.05%. In the largest contemporary US cohort reported to date, most patients undergoing diagnostic catheterization before noncardiac surgery are asymptomatic. The discovery of obstructive coronary artery disease is common, and although randomized clinical trials have found no benefit in outcomes, revascularization is recommended in nearly half of these patients. The overall findings highlight management patterns in this population and the need for greater evidence-based guidelines and practices.

  19. Reduction in operator radiation exposure during transradial catheterization and intervention using a simple lead drape. (United States)

    Iqtidar, Ali F; Jeon, Cathy; Rothman, Richard; Snead, Randall; Pyne, Christopher T


    Transradial access for cardiac catheterization and intervention is a recognized method for reducing complications and improving patient comfort. However, there are concerns over possible increased operator radiation exposure. We tested the hypothesis that a simple lead drape would reduce operator exposure in transradial procedures. Patients undergoing either diagnostic or interventional procedures using transradial access were assigned in an alternating manner to the use of a 0.5-mm lead apron across the patient's abdomen in addition to standard operator protection. Patients were divided into 4 groups: (left enhanced shielding vs left standard shielding; right enhanced shielding vs right standard shielding). Dosimeters were taped to the primary and secondary operators' left wrist and outside the thyroid guard. The operator exposure was measured for each site on every case in centigray. In standard shielded patients, there was no increase in operator exposure between the left and right approach patients at any measurement site. Measured exposure was reduced with enhanced shielding at all dosimeter sites except the secondary operator's collar (both left and right) and the primary operator's collar from the right. There was no significant difference in fluoroscopy, air kerma, or dose area product between standard and enhanced shielded patients. The use of a lead drape reduces the rate of operator radiation exposure at multiple measurement sites. Use of the left radial approach was not associated with an increase in operator exposure compared with the right radial approach. Copyright © 2013 Mosby, Inc. All rights reserved.

    Schmugge, Markus; Speer, Oliver; Kroiss, Sabine; Knirsch, Walter; Kretschmar, Oliver; Rand, Margaret L; Albisetti, Manuela


    Very few studies have investigated dose response of aspirin and agreement of different platelet function assays in children. One hundred five children were studied at baseline and after interventional cardiac catheterization during aspirin treatment and, in cases of aspirin resistance (AR), after dose increase. Results from arachidonate-induced aggregation (AA) were compared with aggregation induced by ADP, PFA-100 closure times (CTs), urinary 11-dehydro-thromboxane B2 (urinary 11-dhTxB2) levels, and Impact-R % surface coverage. Aspirin at 2-5 mg/kg/day inhibited platelet function in a large majority. While 19 % showed bruising and mild epistaxis, no thrombotic complications were recorded. AR was detected by AA in seven children (6.7 %). After dose increase, the majority showed inhibition by aspirin. Infants had higher urinary 11-dhTxB2 baseline levels; this assay showed some correlation with AA. Both assays manifested high sensitivity and specificity for aspirin while inferior results were found for the other assays. With the PFA-100, 15.2 % of patients were found to have AR, but this corresponded to AR by AA in only one of seven children. While there was poor agreement among assays, AA and urinary 11-dhTxB2 show good specificity for the monitoring of aspirin therapy in children. Aspirin at 2-5 mg/kg inhibits platelet function; AR in children is rare and can be overcome by dose increase.

  1. ARFI ultrasound for in vivo hemostasis assessment postcardiac catheterization, part I: preclinical studies. (United States)

    Behler, Russell H; Scola, Mallory R; Nichols, Timothy C; Bellinger, Dwight A; Gallippi, Caterina M


    The world wide prevalence of cardiovascular disease leads to over seven million annual percutaneous coronary catheterization procedures, the majority of which exploit femoral artery access. Femoral puncture sites ('arteriotomies') can be associated with severe vessel complications after sheath removal if hemostasis is not properly achieved. Hemostasis onset is routinely determined by examination for bleeding at the skin puncture; however, clotting along the puncture path can obscure subcutaneous bleeding, and therefore hemostasis is blindly assessed. We hypothesize that hemostasis assessment can be un-blinded by Acoustic Radiation Force Impulse (ARFI) ultrasound. In this first of a two-part series, we present in vivo ARFI hemostasis imaging data obtained in relevant canine models of femoral artery puncture. Above arteriotomies, ARFI-induced displacements were large (3.5 to >5.0 microm) relative to surrounding soft tissue soon after needle removal, which was consistent with our expectation for pooled extravasated blood. ARFI-induced displacements above arteriotomies decreased in magnitude (to approximately 2 microm) some time after needle removal and suggested the onset of hemostasis. This preclinical investigation served as proof of concept and justification for a pilot human study, which is presented in part two of this series.

  2. Capacity planning for cardiac catheterization: a case study. (United States)

    Gupta, Diwakar; Natarajan, Madhu Kailash; Gafni, Amiram; Wang, Lei; Shilton, Don; Holder, Douglas; Yusuf, Salim


    Excessive waiting for procedures such as cardiac catheterization is an important issue for health care systems. Delays are generally attributed to a mismatch between demand and available capacity. Furthermore, due to the dynamic nature of short-term referral rates, procedure times, and patients' medical urgency, all of which are important contributors to the problem of excessive waiting time, it has been difficult to predict capacity needs accurately. The objective of our paper is to demonstrate how such calculations could be performed. After constructing a patient flow model and populating it with appropriate data from 16 consecutive months of operations (n=6215 referrals) of a regional cardiac centre in Ontario, we used computer simulation to simulate the operations of catheterization laboratories in several "what-if" scenarios. We divided the patients into three urgency categories: U1--hospitalized patients, U2--urgent outpatients, U3--elective outpatients. We tested the accuracy of the model by comparing a 1-year sample of computer simulation with actual data which resulted in a highly significant correlation of 0.94. We observed from the referral cohort that waiting times were long, both overall and within each urgency category. We observed from the simulation models that: (1) a one-time infusion of capacity to clear the backlog failed to reduce the waiting times; (2) targeting extra capacity to highest urgency categories reduced waiting times overall and also benefited low urgency patients for whom specific increased capacity was not earmarked; (3) there were no significant effects on waiting times if in some cases patients or referring physicians were able to choose their cath physician; and (4) in situations where the arrival rates increased overall or within specific urgency categories, waiting times increased dramatically and failed to return to baseline for several months to years for the low urgency patients.

    The development of right heart catheterization has provided the clinician the ability to diagnose patients with congenital and acquired right heart disease, and to monitor patients in the ICU with significant cardiovascular illnesses. The development of bedside pulmonary artery catheterization has become a standard of care for the critically ill patient since its introduction into the ICU almost 40 years ago. However, adoption of this procedure into the mainstream of clinical practice occurre...

  7. Three-week or one-week bladder catheterization for hypospadias repair? A retrospective-prospective observational study of 189 patients. (United States)

    Daher, Paul; Khoury, Antoine; Riachy, Edward; Atallah, Bachir


    While there is little scientific evidence over the optimal duration for transurethral bladder catheterization after hypospadias repair, most surgeons leave the catheter for 7-10 days. We herein describe our experience with bladder catheterization for three weeks after hypospadias repair, an approach not previously described in the literature. We reviewed the charts of 189 patients who underwent hypospadias repair by a single pediatric urologist. The study population was divided as follows: group 1 consisted of children operated between March 2007 and September 2010 and whose catheters were left for one week (n=95); group 2 consisted of those operated between September 2010 and July 2013 and whose catheters were left for three weeks (n=94). The primary objective of the study was to compare complication rates between the two groups. Secondary outcomes were evaluation of the effect of age, surgical technique, curvature, and hypospadias degree as potential factors for postoperative complications. Median age at hypospadias repair was 18 months (range, 3-100 months) in group 1, and 16 months (range, 2-96 months) in group 2, P=.209. The complication rate was 22.1% (n=21) for group 1 and 7.4% (n=7) for group 2, P=.005. Complications observed in group 1 and 2 were meatal stenosis (n=4 and 2, respectively) and urethro-cutaneous fistulas (n=17 and 5, respectively). Coronal fistulas manifested more frequently in patients in group 1 compared to those in group 2 (13.7% vs. 3.2%, P=.01). Complications were observed in 20 patients out of 139 (11.5%) after Duplay, and in 8 patients out of 15 (53.3%) after Duckett (Phypospadias repair are associated with a better outcome and fewer complications.

    Full Text Available Guramrinder S Thind,1 Raunak Parida,1 Nishant Gupta2 1SDM College of Medical Sciences and Hospital, Dharwad, Karnataka, India; 2University of Texas at Houston, Houston, TX, USAAbstract: Many recent innovations have been made in developing new antiplatelet and ­anticoagulant drugs in the last few years, with a total of nine new antithrombotic drugs approved by the Food and Drug Administration after the year 2000. This has revolutionized the medical therapy given to manage acute coronary syndrome and support cardiac catheterization. The concept of dual antiplatelet therapy has been emphasized, and clopidogrel has emerged as the most-popular second antiplatelet drug after aspirin. Newer P2Y12 inhibitors like prasugrel and ticagrelor have been extensively studied and compared to clopidogrel. The role of glycoprotein (Gp IIb/IIIa inhibitors is being redefined. Other alternatives to unfractionated heparin have become available, of which enoxaparin and bivalirudin have been studied the most. Apart from these, many more drugs with novel therapeutic targets are being studied and are currently under development. In this review, current evidence on these drugs is presented and analyzed in a way that would facilitate decision making for the clinician. For this analysis, various high-impact clinical trials, pharmacological studies, meta-analyses, and reviews were accessed through the MEDLINE database. Adopting a unique interdisciplinary approach, an attempt has been made to integrate pharmacological and clinical evidence to better understand and appreciate the pros and cons of each of these classes of drugs.

    measure and compare the quality of life of neurogenic bladder patients using intermittent urinary catheterization who were going through rehabilitation in Brazil and Portugal. multicenter, quantitative, cross-sectional, observational-analytic and correlational study executed in Brazil and Portugal. Two data collection tools were used, being one questionnaire with sociodemographic and clinical data and the World Health Organization Quality of Life-bref. Patients were included who were over 18 years of age, suffering from neurogenic urinary bladder and using intermittent urinary catheterization. in the sample of Brazilian (n = 170) and Portuguese (n = 52) patients, respectively, most patients were single (87-51.2%; 25-48.1%), had finished primary education (47-45.3%; 31-59.6%) and were retired (70-41.2%; 21-40.4%). Spinal cord injury was the main cause of using the urinary catheter in both countries. The Brazilian patients presented higher mean quality of life scores in the psychological domain (68.9) and lower scores in the physical domain (58.9). The Portuguese patients presented higher scores in the psychological domain (68.4) and lower scores in the environment domain (59.4). The execution of intermittent urinary self-catheterization was significant for both countries. in the two countries, these patients' quality of life can be determined by the improvement in the urinary symptoms, independence, self-confidence, social relationships and access to work activities. mensurar e comparar a qualidade de vida de pacientes com bexiga neurogênica em uso do cateterismo urinário intermitente em processo de reabilitação, no Brasil e em Portugal. estudo multicêntrico, Brasil e Portugal, quantitativo, transversal, observacional-analítico e correlacional.

    Pedro Henrique Comerlato

    Full Text Available Summary Introduction: Central venous catheters are fundamental to daily clinical practice. This procedure is mainly performed by residents, often without supervision or structured training. Objective: To describe the characteristics of central venous catheterization and the complication rate related to it. Method: Retrospective cohort study. Adult patients undergoing central venous catheter insertion out of the intensive care unit (ICU of a teaching hospital were selected from March 2014 to February 2015. Data were collected from medical charts using an electronic form. Clinical and laboratory characteristics from patients, procedure characteristics, and mechanical and infectious complications rates were assessed. Patients with and without complications were compared. Results: Three hundred and eleven (311 central venous catheterizations were evaluated. The main reasons to perform the procedure were lack of peripheral access, chemotherapy and sepsis. There were 20 mechanical complications (6% of procedures. Arterial puncture was the most common. Procedures performed in the second semester were associated with lower risk of complications (odds ratio 0.35 [95CI 0.12-0.98; p=0.037]. Thirty-five (35 catheter-related infection cases (11.1% were reported. They were related to younger patients and procedures performed by residents with more than one year of training. Procedures performed after the first trimester had a lower chance of infection. Conclusion: These results show that the rate of mechanical complications of central venous puncture in our hospital is similar to the literature, but more attention should be given to infection prevention measures.

  17. Learning-based modeling of endovascular navigation for collaborative robotic catheterization. (United States)

    Rafii-Tari, Hedyeh; Liu, Jindong; Lee, Su-Lin; Bicknell, Colin; Yang, Guang-Zhong


    Despite rapid growth of robot assisted catheterization in recent years, most current platforms are based on master-slave designs with limited operator-robot collaborative control and automation. Under this setup, information concerning subject specific behavior and context-driven manoeuvre is not re-utilized for subsequent intervention. For endovascular catheterization, the robot itself is designed with little consideration of underlying skills and associated motion patterns. This paper proposes a learning-based approach for generating optimum motion trajectories from multiple demonstrations of a catheterization task such that it can be used for automating catheter motion within a collaborative setting. Motion models are generated from experienced manipulation of a catheterization procedure and replicated using a robotic catheter driver to assist inexperienced operators. Catheter tip motions of the automated approach are compared against the manual training sets for validating the proposed framework. The results show significant improvements in the quality of catheterization, which facilitate the design of hands-on collaborative robots that make full use of the natural skills of the operators.

  18. Knowledge and meaning of cardiac catheterization from the perspective of cardiac patients

    Directory of Open Access Journals (Sweden)

    Yana Thalita Barros de Oliveira Castro


    Full Text Available Objective: to describe the knowledge and significance of cardiac catheterization from cardiac patients’ perspective. Methods: descriptive and qualitative study of patients undergoing cardiac catheterization. Five categories were identified through content analysis. Results: knowledge of patients on cardiac catheterization proved to be limited; the subject was surrounded by lack of knowledge. Cardiac catheterization means a treatment for unblocking coronary arteries and it is confused with therapeutic purposes. There were reports of symptoms related to heart disease such as fatigue and chest pain and related to the exams such as worry, anxiety, depression, fear and restlessness generated, mainly, by expectations of the unknown. The majority of the respondents proved to be satisfied with the results of the exam, due to the discovery and treatment of heart diseases. Conclusion: cardiac catheterization means treatment and clearance of coronary arteries and it is confused with therapeutic purposes. Feelings such as worry, anxiety, fear and restlessness are described when patients are subjected to examination, generated mainly by expectations of the unknown.

  19. A Simulation-based, cognitive assessment of resident decision making during complex urinary catheterization scenarios. (United States)

    Nathwani, Jay N; Law, Katherine E; Witt, Anna K; Ray, R D; DiMarco, S M; Pugh, C M


    This study explores general surgery residents' decision making skills in uncommon, complex urinary catheter scenarios. 40 residents were presented with two scenarios. Scenario A was a male with traumatic urethral injury and scenario B was a male with complete urinary blockage. Residents verbalized whether they would catheterize the patient and described the workup and management of suspected pathologies. Residents' decision paths were documented and analyzed. In scenario A, 45% of participants chose to immediately consult Urology. 47.5% named five diagnostic tests to decide if catheterization was safe. In scenario B, 27% chose to catheterize with a 16 French Coude. When faced with catheterization failure, participants randomly upsized or downsized catheters. Chi-square analysis revealed no measurable consensus amongst participants. Residents need more training in complex decision making for urinary catheterization. The decision trees generated in this study provide a useful blueprint of residents' learning needs. Exploration of general surgery residents' decision making skills in uncommon, complex urinary catheter scenarios revealed major deficiencies. The resulting decision trees reveal residents' learning needs. Copyright © 2017 Elsevier Inc. All rights reserved.

    We sought to develop a scoring system that predicts the risk of serious adverse events (SAE's) for individual pediatric patients undergoing cardiac catheterization procedures. Systematic assessment of risk of SAE in pediatric catheterization can be challenging in view of a wide variation in procedure and patient complexity as well as rapidly evolving technology. A 10 component scoring system was originally developed based on expert consensus and review of the existing literature. Data from an international multi-institutional catheterization registry (CCISC) between 2008 and 2013 were used to validate this scoring system. In addition we used multivariate methods to further refine the original risk score to improve its predictive power of SAE's. Univariate analysis confirmed the strong correlation of each of the 10 components of the original risk score with SAE attributed to a pediatric cardiac catheterization (P CRISP) that corresponds to an increase in value of area under a receiver operating characteristic curve (AUC) from 0.715 to 0.741. The CRISP score predicts risk of occurrence of an SAE for individual patients undergoing pediatric cardiac catheterization procedures. © 2015 Wiley Periodicals, Inc.

    Pleural and pericardial effusions are extremely rare complications of umbilical venous catheterization in newborns. A preterm male infant weighing 850g, with insertion of an umbilical venous catheter (UVC) developed massive right pleural and pericardial effusions. The position of catheter tip was verified by chest radiography and echocardiography. The effusions were drained by thoracentesis and pericardiocentesis without complication, and were biochemically similar as total parenteral infusion which infused through catheter.

  4. Factors Influencing ACT After Intravenous Bolus Administration of 100 IU/kg of Unfractionated Heparin During Cardiac Catheterization in Children. (United States)

    Muster, Ileana; Haas, Thorsten; Quandt, Daniel; Kretschmar, Oliver; Knirsch, Walter


    Anticoagulation using intravenous bolus administration of unfractionated heparin (UFH) aims to prevent thromboembolic complications in children undergoing cardiac catheterization (CC). Optimal UFH dosage is needed to reduce bleeding complications. We analyzed the effect of bolus UFH on activated clotting time (ACT) in children undergoing CC focusing on age-dependent, anesthesia-related, or disease-related influencing factors. This retrospective single-center study of 183 pediatric patients receiving UFH during CC analyzed ACT measured at the end of CC. After bolus administration of 100 IU UFH/kg body weight, ACT values between 105 and 488 seconds were reached. Seventy-two percent were within target level of 160 to 240 seconds. Age-dependent differences were not obtained ( P = .407). The ACT values were lower due to hemodilution (total fluid and crystalloid administration during CC, both P ACT values but occurred more frequently in children between 1 month and 1 year of age (91%). In conclusion, with a bolus of 100 IU UFH/kg, an ACT target level of 160 to 240 seconds can be achieved during CC in children in 72%, which is influenced by hemodilution and anticoagulant and antiplatelet premedication but not by age.

    This study aimed to evaluate the effectiveness of massage with or without guided imagery in reducing anxiety prior to cardiac catheterization. A total of 55 inpatients and outpatients received massage, guided imagery, or massage with guided imagery prior to cardiac catheterization. Self-reported anxiety levels and blood pressure (BP) and heart rate (HR) were evaluated in participants and a matched comparison group. Massage with and without guided imagery resulted in significant reductions in self-reported anxiety (p Massage with or without guided imagery immediately reduced self-reported anxiety. This pilot study has certain limitations: a non-randomized, convenience sample and a matched control group that was created retrospectively. However, the study indicates a benefit to providing massage or massage with guided imagery prior to anxiety-inducing medical procedures such as cardiac catheterization. Copyright © 2014 Elsevier Ltd.

  6. Paraplegia following cervical epidural catheterization using loss of resistance technique with air: a case report. (United States)

    Chae, Yun Jeong; Han, Kyung Ream; Park, Hyung Bae; Kim, Chan; Nam, Si Gweon


    We report a case of paraplegia without neurologic deficit of upper extremities following cervical epidural catheterization using air during the loss of resistance technique. A 41-year-old woman diagnosed with complex regional pain syndrome had upper and lower extremity pain. A thoracic epidural lead was inserted for a trial spinal cord stimulation for treating lower extremity pain and cervical epidural catheterization was performed for treating upper extremity pain. Rapidly progressive paraplegia developed six hours after cervical epidural catheterization. Spine CT revealed air entrapment in multiple thoracic intervertebral foraminal spaces and surrounding epidural space without obvious spinal cord compression before the decompressive operation, which disappeared one day after the decompressive operation. Her paraplegia symptoms were normalized immediately after the operation. The presumed cause of paraplegia was transient interruption of blood supply to the spinal cord through the segmental radiculomedullary arteries feeding the spinal cord at the thoracic level of the intervertebral foramen caused by the air.

  7. A Review of the Effects of Sedation on Thermoregulation: Insights for the Cardiac Catheterization Laboratory. (United States)

    Conway, Aaron


    To examine the effects that the sedative and analgesic medications commonly used in the cardiac catheterization laboratory have on thermoregulation. A structured review strategy was used. MEDLINE and CINAHL were searched for published studies, and reference lists of retrieved studies were scrutinized for further studies. Data were extracted using a standardized extraction tool. A total of nine studies examined the effect that sedative and analgesic medications have on thermoregulation. Midazolam has minimal impact on thermoregulation, whereas opioids, dexmedetomidine, and propofol markedly decrease vasoconstriction and shivering thresholds. Patients who receive sedation in the cardiac catheterization laboratory may be at risk of hypothermia because of the use of medications that impair thermoregulation. Further research is required to identify the prevalence of unplanned hypothermia during sedation in the cardiac catheterization laboratory. Copyright © 2016 American Society of PeriAnesthesia Nurses.

    Full Text Available UTI is the most common infection in all ages and urinary catheters especially long-term catheterization are important predisposing factors of UTI. Urinary catheters are used in different hospital wards as a complementary curative method for the patients who are undergone various surgical procedures, such as : cesarean, hysterectomy , laparotomy, etc and they who are unable to control their voided urine . 226 urine specimens were collected from 119 catheterized patients which had been hospitalized in seven wards of Razi and Golestan hospitals in Ahwas city . At least two urine specimens were collected from each patient , before and after the insertion of the catheter . All of the specimens were inoculated to suitable Media, after transportation to the Microbiology Lab . Isolated colonies were identified and their resistance patterns were determined by the standard disk diffusion method (Kirby –Bauer procedure to 8 different antibiotics. 38 cases (43.6% out of 87 patients showed Bacteriuria in the end of catheterization . They had no bacteriuria symptoms or sign before the catheterization. The most cases(28.9% of bacteriuria occured in 30-39 years group and the lowest cases (2.6 % of them occured in 60-69 years group. Out of 50 bacterial strains isolated from urine cultures , E.coil (with 17 cases was the highest (34% and Staphylococcus aureus , Klebsiella pneumoniae , Edwardsiella tarda , Enterobacter sakazakii (with 2% for each were the lowest cases.

    Fumincelli, Laís; Mazzo, Alessandra; Martins, José Carlos Amado; Henriques, Fernando Manuel Dias; Cardoso, Daniela; Rodrigues, Manuel Alves


    This study aimed to examine and map the scientific evidences regarding quality of life in neurogenic bladder patients and consequently their caregivers by means of a scoping review. This is a scoping review proposal of the Joanna Briggs Institute. It was conducted to examine and map the scientific evidences about quality of life (QoL) in neurogenic bladder patients and their caregivers, to identify the meanings attributed to QoL and its relation with intermittent urinary catheterization. The following guiding question was: "What scientific evidence has been produced on the QoL of neurogenic bladder patients using intermittent urinary catheterization and their caregivers?" A total of 2945 research studies were identified using The Cochrane Library, CINAHL, LILACS, Academic Search Premier (via EBSCO platform), PubMed, SCOPUS, the platforms Web of Science, the b-on and Gray Literature. The keywords established were patient, intermittent urinary catheterization, neurogenic urinary bladder, quality of life and caregiver. From 2,945 studies, 13 studies were selected. Most of the selected studies that analyzed variables related to the patients' QoL were regarding the urinary catheterization technique, assessment of urinary incontinence, individual perceptions of the procedure and experiences with urinary catheter in childhood and adult life. The meanings attributed to QoL, when compared to adult and child individuals with normal bladder functioning, presented lower QoL scores. Concerning caregivers, the QoL of caregivers of children using intermittent urinary catheterization demonstrated low scores. The QoL of patient's who use intermittent urinary catheterization can be determined by improvement of urinary symptoms and self-confidence. Research related to QoL of patients who use urinary catheter indicates the importance of adequate professional support and appropriate health public policies. © 2017 Sigma Theta Tau International.

  10. Intra-procedural continuous dialysis to facilitate interventional catheterization in pediatric patients with severe renal failure. (United States)

    Opina, Angeline D; Qureshi, Athar M; Brewer, Eileen; Elenberg, Ewa; Swartz, Sarah; Michael, Mini; Justino, Henri


    Interventional catheterization procedures may be needed for patients with severe renal failure who are dependent on dialysis. To avoid the risk of fluid overload and electrolyte derangement during complex procedures in this oliguric/anuric patient population, we performed intra-procedural dialysis, either continuous renal replacement therapy (CRRT) or continous cycling peritoneal dialysis (CCPD). We performed a retrospective review of a cohort of pediatric patients, ages 0-18 years, with dialysis-dependent renal failure who received CRRT or CCPD during catheterization procedures from January 2013 to March 2016. Eight patients underwent a total of nine interventional catheterization procedures while receiving intra-procedural dialysis. Median age was 4.5 years (range 8 months to 17 years) and weight, 11.6 kg (11.2-62.6 kg). Six patients had end-stage renal disease (ESRD) and two patients had acute kidney injury (AKI), one due to hepatorenal syndrome and one due to multifactorial causes associated with congenital heart disease. The most common reason for catheterization was occlusive venous thrombosis requiring recanalization. CRRT was used during five cases and CCPD during four cases. Median procedure time was 337 min (95-651 min) and median contrast dose 4.2 mL kg-1 (1.2-8.2 mL kg-1 ). Euvolemia was maintained based on pre- and post-catheterizations weights, and no significant electrolyte abnormalities occurred based on lab monitoring during and post-procedure. Intra-procedural dialysis using CRRT or CCPD enables even small pediatric patients with severe renal failure to undergo long and complex interventional catheterizations by reducing the risk of fluid overload and electrolyte abnormalities. Collaboration between nephrology, cardiology, and dialysis teams is necessary for successful management of this challenging patient population. © 2017 Wiley Periodicals, Inc.

    Koroglu, M.; Demir, M.; Koroglu, B.K.; Sezer, M.T.; Akhan, O.; Yildiz, H.; Yavuz, L.; Baykal, B.; Oyar, O. [Suleyman Demirel Univ., Isparta (Turkey). Depts. of Radiology, Internal Medicine and Anesthesiology


    Purpose: To compare the success and immediate complication rates of the anatomical landmark method (group 1) and the radiologically (combined real-time ultrasound and fluoroscopy) guided technique (group 2) in the placement of central venous catheters in emergent hemodialysis patients. Material and Methods: The study was performed prospectively in a randomized manner. The success and immediate complication rates of radiologically guided placement of central venous access catheters through the internal jugular vein (n = 40) were compared with those of the anatomical landmark method (n 40). The success of placement, the complications, the number of passes required, and whether a single or double-wall puncture occurred were also noted and compared. Results: The groups were comparable in age and sex. The indication for catheter placement was hemodialysis access in all patients. Catheter placement was successful in all patients in group 2 and unsuccessful in 1 (2.5%) patient in group 1. All catheters functioned adequately and immediately after the placement (0% initial failure rate) in group 2, but 3 catheters (7.5% initial failure rate) were non-functional just after placement in group 1. The total number of needle passes, double venous wall puncture, and complication rate were significantly lower in group 2. Conclusion: Percutaneous central venous catheterization via the internal jugular vein can be performed by interventional radiologists with better technical success rates and lower immediate complications. In conclusion, central venous catheterization for emergent dialysis should be performed under both real-time ultrasound and fluoroscopic guidance.

    Kitisomprayoonkul, Wasuwat; Sungkapo, Peeraporn; Taveemanoon, Suganya; Chaiwanichsiri, Dootchai


    To identify the incidence and risk factors of medical complications during inpatient stroke rehabilitation. Stroke patients (n = 118) admitted to the Thai Red Cross Rehabilitation Center between August 2006 and January 2007 were prospectively evaluated throughout inpatient rehabilitation to identify incidence of complications. Eighty-three patients (70.3%) experienced at least one complication. The common complications were post-stroke depression (56.6%), musculoskeletal pain (28%), urinary tract infection (UTI) (17.8%), and complex regional pain syndrome (CRPS) type I (15.3%). Others were pneumonia (4.2%), cardiovascular complications (4.2%), falls (4.2%), upper GI bleeding (3.2%), seizure (2.5%), and pressure ulcer (1.7%). Fourteen patients (11.8%) were referred to the acute care hospital because of severe medical complications. History of myocardial infarction, low admission Barthel ADL Index, urinary incontinence, indwelling catheterization, and dysphagia were risk factors of complications (p CRPS type I was limited shoulder range of motion (RR 3.13, p = 0.035), pneumonia was aspiration (RR 145.33, p history of myocardial infarction (RR 7.70, p = 0.037). The incidence of medical complication is 70.3%. Post-stroke depression, musculoskeletal pain, UTI and CRPS type I are the common complications. The risk factors of complications are low admission BAI, history of myocardial infarction, urinary incontinence, indwelling catheterization, and dysphagia. Awareness and screening of risk factors should be implemented to lower the incidence.

    Conclusions: Most urinary catheters marketed in developing countries are unidentifiable after unpacking. A catheterization diary is a useful tool for solving catheter-related problems, and its application in health-care facilities should be encouraged. Companies marketing Foley catheters should print the catheter name on both the catheter packaging and on the catheter itself.

    Pediatric and Congenital Interventional Cardiology is the practice of catheter-based techniques that improve cardiac physiology and circulation through the treatment of heart disease in children and adults with congenital or acquired heart defects. Over the last decade, and since last published training guidelines for pediatric cardiac catheterization and interventional cardiology were published in 2005 [1] the field of Pediatric and Congenital Cardiac Catheterization has evolved into a predominantly interventional discipline. As there is no sub-specialty certification for interventional cardiac catheterization in pediatrics, the Congenital Heart Disease Committee of the Society of Cardiovascular Angiography and Interventions has put together this consensus statement for advanced training in pediatric and congenital interventional cardiac catheterization. The statement puts forth recommendations for program infrastructure in terms of teaching, personnel, equipment, facilities, conferences, patient volume and trainee assessment. This is meant to set a standard for training programs as well as giving applicants a basis on which to judge and compare programs. © 2014 Wiley Periodicals, Inc.

    Conclusions: Both propofol–ketamine and sevoflurane provided effective sedation and analgesia during pediatric cardiac catheterization. But propofol–ketamine combination was superior to sevoflurane because the incidence of agitation, nausea and vomiting in patients given sevoflurane was significantly higher than in ketofol group.

  1. Incidence and management of life-threatening adverse events during cardiac catheterization for congenital heart disease. (United States)

    Lin, C Huie; Hegde, Sanjeet; Marshall, Audrey C; Porras, Diego; Gauvreau, Kimberlee; Balzer, David T; Beekman, Robert H; Torres, Alejandro; Vincent, Julie A; Moore, John W; Holzer, Ralf; Armsby, Laurie; Bergersen, Lisa


    Continued advancements in congenital cardiac catheterization and interventions have resulted in increased patient and procedural complexity. Anticipation of life-threatening events and required rescue measures is a critical component to preprocedural preparation. We sought to determine the incidence and nature of life-threatening adverse events in congenital and pediatric cardiac catheterization, risk factors, and resources necessary to anticipate and manage events. Data from 8905 cases performed at the 8 participating institutions of the Congenital Cardiac Catheterization Project on Outcomes were captured between 2007 and 2010 [median 1,095/site (range 133-3,802)]. The incidence of all life-threatening events was 2.1 % [95 % confidence interval (CI) 1.8-2.4 %], whereas mortality was 0.28 % (95 % CI 0.18-0.41 %). Fifty-seven life-threatening events required cardiopulmonary resuscitation, whereas 9 % required extracorporeal membrane oxygenation. Use of a risk adjustment model showed that age events. Using this model, standardized life-threatening event ratios were calculated, thus showing that one institution had a life-threatening event rate greater than expected. Congenital cardiac catheterization and intervention can be performed safely with a low rate of life-threatening events and mortality; preprocedural evaluation of risk may optimize preparation of emergency rescue and bailout procedures. Risk predictors (age < 1, hemodynamic vulnerability, and procedure risk category) can enhance preprocedural patient risk stratification and planning.

  5. Venous anomalies as potentially lethal risk factors during ordinary catheterization

    Directory of Open Access Journals (Sweden)

    Savino Occhionorelli


    Full Text Available Venous malformations are rare but possible findings too, constituting a further risk factor for central venous catheter procedures. Herein we describe a case of death because of an innominate vein perforation by a catheter that incidentally was tucked into a sacciform malformation. Even if the technology advancement is constantly offering us new investigation tools, up to now diagnostic options are limited in the detection of those malformations that could potentially lead to dramatic complications as the described one. The present work raises the awareness about rare venous anomalies and their potential clinical implications. A proper literature review and diagnostic implementation proposal are reported.

  6. Bilateral chylothorax as a complication of internal jugular vein cannulation

    Directory of Open Access Journals (Sweden)

    Puneet Saxena


    Full Text Available Central venous catheterization is one of the most prevalent procedures in the Intensive Care Unit. Complications are reported in about 15% of the patients and usually comprise of infection, arterial puncture, malpositioning, pneumothorax, local hematoma, hemothorax, and so on. Chylothorax is a rare complication of this procedure. We present a 42-year-old lady, who developed bilateral massive chylothorax after cannulation of her left internal jugular vein (IJV, due to direct injury to the thoracic duct during the procedure. The patient was successfully managed with bilateral chest tube drainage and omission of oral feeds for four days. Development of bilateral chylothorax as a complication of IJV cannulation is rare, but merits reporting, in view of a large number of central venous cannulations being undertaken. Critical care professionals should be aware of this rare complication of a common procedure to facilitate early identification and institute appropriate therapy.

  7. Radiation dose benchmarks during cardiac catheterization for congenital heart disease in the United States. (United States)

    Ghelani, Sunil J; Glatz, Andrew C; David, Sthuthi; Leahy, Ryan; Hirsch, Russel; Armsby, Laurie B; Trucco, Sara M; Holzer, Ralf J; Bergersen, Lisa


    The aim of this study was to define age-stratified, procedure-specific benchmark radiation dose levels during interventional catheterization for congenital heart disease. There is a paucity of published literature with regard to radiation dose levels during catheterization for congenital heart disease. Obtaining benchmark radiation data is essential for assessing the impact of quality improvement initiatives for radiation safety. Data were obtained retrospectively from 7 laboratories participating in the Congenital Cardiac Catheterization Project on Outcomes collaborative. Total air kerma, dose area product, and total fluoroscopy time were obtained for the following procedures: 1) patent ductus arteriosus closure; 2) atrial septal defect closure; 3) pulmonary valvuloplasty; 4) aortic valvuloplasty; 5) treatment of coarctation of aorta; and 6) transcatheter pulmonary valve placement. Between January 2009 and July 2013, 2,713 cases were identified. Radiation dose benchmarks are presented including median, 75th percentile, and 95th percentile. Radiation doses varied widely between age groups and procedure types. Radiation exposure was lowest in patent ductus arteriosus closure and highest in transcatheter pulmonary valve placement. Total fluoroscopy time was a poor marker of radiation exposure and did not correlate well with total air kerma and dose area product. This study presents age-stratified radiation dose values for 6 common congenital heart interventional catheterization procedures. Fluoroscopy time alone is not an adequate measure for monitoring radiation exposure. These values will be used as baseline for measuring the effectiveness of future quality improvement activities by the Congenital Cardiac Catheterization Project on Outcomes collaborative.

  8. The effects of music intervention on anxiety in the patient waiting for cardiac catheterization. (United States)

    Hamel, W J


    Hospitalization causes anxiety for many patients. It increases when patients anticipate their turn for cardiac catheterization. Music therapy reduces the psychophysiologic effects of anxiety and stress through the relaxation response. To determine the effects of music therapy an anxiety, heart rate and arterial blood pressure in patients waiting for their scheduled cardiac catheterization. In a quasi-experimental, pretest-posttest design, 101 subjects were randomly assigned to either the test group: those who listened to 20 minutes of preselected music, or the control group: those who received treatment as usual. Subject anxiety levels and physiological values were measured while waiting their turn for cardiac catheterization and just prior to departure to the cardiac lab. 63 males and 38 females participated in the study. There was a statistically significant reduction in anxiety in the test group alone (P = 0.003) and in comparing the test to the control group (P = 0.004). In comparing the initial and departure physiologic values, it was noted that both heart rate and systolic blood pressure dropped in the test group, but increased in the control group. Within gender groups, there were no statistically significant differences in hemodynamics or STAI scores, but between gender groups there were significantly higher diastolic blood pressure in males and STAI initial and departure scores for females. Patients waiting for their cardiac catheterization benefit from music therapy. Anxiety and the heightened physiological values elicited by the stress response are reduced. Results also suggest that women waiting for cardiac catheterization experience a higher level of anxiety than males.

    Full Text Available OBJECTIVE Anesthetic management for interventional cardiac procedures/cardiac catheterization in pediatric patients is challenging. Cardiac anomalies vary from simple to complex congenital cardiac anomalies, shunts may be present at multiple levels and patients may be profoundly cyanotic, may be with ventricular dysfunction. They usually require sedation and analgesia to maintain steady stable state. In adults, such type of procedures can be well managed with local anesthesia. METHODS Fifty patients were included in the study. They were randomly divided into two groups- Group A (n=25 patients received femoral N. block along with IV sedation and analgesia while group B (n=25 patients received only IV sedation and analgesia. Both groups were compared for hemodynamics, pain score and requirement of IV anesthetic agents and any complications if come up. RESULTS Group A patients required IV ketamine 3.24mg/kg (±0.31SD as compared to 5.58mg/kg (±1.6SD in group B, which suggests significantly reduced requirement of IV anesthetic agents in group where femoral nerve block has been given. Hemodynamic parameters remained stable and comparable (no statistically significant variation Pain score was less in group A patients than group B. CONCLUSION It has been observed that Group A patients required less dosages of IV anesthetic agents, with stable hemodynamics and less pain score and sedation score as compared to group B patients.

  10. Usefulness of lavage cytology during endoscopic transpapillary catheterization into the gallbladder in the cytological diagnosis of gallbladder disease. (United States)

    Naito, Yoshiki; Okabe, Yoshinobu; Kawahara, Akihiko; Taira, Tomoki; Isida, Yusuke; Kaji, Ryouhei; Sata, Michio; Ureshino, Hiroki; Mikagi, Kazuhiro; Kinoshita, Hisafumi; Yasumoto, Makiko; Kusano, Hironori; Kage, Masayoshi; Yano, Hirohisa


    Many studies have reported methods of cell collection involving percutaneous transhepatic cholangiodrainage (PTCD) and fine-needle aspiration cytology for the diagnosis of gallbladder disease. However, few studies have described the use of a transpapillary approach, i.e., endoscopic transpapillary catheterization into the gallbladder (ETCG). In this study, we analyzed cells collected by ETCG to evaluate its usefulness in the cytological diagnosis of gallbladder disease. The subjects were 19 patients who had undergone ETCG for the diagnosis of gallbladder disease. Of these patients, 11 and 8 had gallbladder cancer and benign gallbladder disease, respectively. We also evaluated the diagnostic accuracy of PTCD cytology performed in 15 patients with gallbladder cancer.Specimens were cytologically diagnosed as normal or benign, indeterminate, suspected malignancy, malignant, and inadequate in 47% (9/19), 11% (2/19), 0% (0/19), 37% (7/19), and 5% (1/19) of patients, respectively. Specimens were diagnosed as malignant, indeterminate, normal or benign, and inadequate in 7, 2, 1, and 1, respectively, of the 11 patients diagnosed with gallbladder cancer. The sensitivity and specificity of ETCG cytology were 78 and 100%, respectively, whereas the diagnostic accuracy of PTCD cytology was 20% (3/15). None of the patients developed complications of ETCG. Despite its technical difficulty, ETCG for bile cytology allows the collection of adequate cell numbers from patients with benign disease or gallbladder cancer and facilitates a cytological diagnosis, making it a useful method for collecting cells.

  12. Ultrasound guidance versus anatomical landmarks for internal jugular vein catheterization. (United States)

    Brass, Patrick; Hellmich, Martin; Kolodziej, Laurentius; Schick, Guido; Smith, Andrew F


    Central venous catheters (CVCs) can help with diagnosis and treatment of the critically ill. The catheter may be placed in a large vein in the neck (internal jugular vein), upper chest (subclavian vein) or groin (femoral vein). Whilst this is beneficial overall, inserting the catheter risks arterial puncture and other complications and should be performed with as few attempts as possible. Traditionally, anatomical 'landmarks' on the body surface were used to find the correct place in which to insert catheters, but ultrasound imaging is now available. A Doppler mode is sometimes used to supplement plain 'two-dimensional' ultrasound. The primary objective of this review was to evaluate the effectiveness and safety of two-dimensional (imaging ultrasound (US) or ultrasound Doppler (USD)) guided puncture techniques for insertion of central venous catheters via the internal jugular vein in adults and children. We assessed whether there was a difference in complication rates between traditional landmark-guided and any ultrasound-guided central vein puncture.Our secondary objectives were to assess whether the effect differs between US and USD; whether the effect differs between ultrasound used throughout the puncture ('direct') and ultrasound used only to identify and mark the vein before the start of the puncture procedure (indirect'); and whether the effect differs between different groups of patients or between different levels of experience among those inserting the catheters. We searched the Central Register of Controlled Trials (CENTRAL) (2013, Issue 1), MEDLINE (1966 to 15 January 2013), EMBASE (1966 to 15 January 2013), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to 15 January 2013 ), reference lists of articles, 'grey literature' and dissertations. An additional handsearch focused on intensive care and anaesthesia journals and abstracts and proceedings of scientific meetings. We attempted to identify unpublished or ongoing studies

  13. A multi-region assessment of population rates of cardiac catheterization and yield of high-risk coronary artery disease

    Directory of Open Access Journals (Sweden)

    Clement Fiona M


    Full Text Available Abstract Background There is variation in cardiac catheterization utilization across jurisdictions. Previous work from Alberta, Canada, showed no evidence of a plateau in the yield of high-risk disease at cardiac catheterization rates as high as 600 per 100,000 population suggesting that the optimal rate is higher. This work aims 1 To determine if a previously demonstrated linear relationship between the yield of high-risk coronary disease and cardiac catheterization rates persists with contemporary data and 2 to explore whether the linear relationship exists in other jurisdictions. Methods Detailed clinical information on all patients undergoing cardiac catheterization in 3 Canadian provinces was available through the Alberta Provincial Project for Outcomes Assessment in Coronary Heart (APPROACH disease and partner initiatives in British Columbia and Nova Scotia. Population rates of catheterization and high-risk coronary disease detection for each health region in these three provinces, and age-adjusted rates produced using direct standardization. A mixed effects regression analysis was performed to assess the relationship between catheterization rate and high-risk coronary disease detection. Results In the contemporary Alberta data, we found a linear relationship between the population catheterization rate and the high-risk yield. Although the yield was slightly less in time period 2 (2002-2006 than in time period 1(1995-2001, there was no statistical evidence of a plateau. The linear relationship between catheterization rate and high-risk yield was similarly demonstrated in British Columbia and Nova Scotia and appears to extend, without a plateau in yield, to rates over 800 procedures per 100,000 population. Conclusions Our study demonstrates a consistent finding, over time and across jurisdictions, of linearly increasing detection of high-risk CAD as population rates of cardiac catheterization increase. This internationally-relevant finding

  14. Hyperoxaluria, Hypocitraturia, Hypomagnesiuria, and Lack of Intestinal Colonization by Oxalobacter formigenes in a Cervical Spinal Cord Injury Patient with Suprapubic Cystostomy, Short Bowel, and Nephrolithiasis

    Directory of Open Access Journals (Sweden)

    Subramanian Vaidyanathan


    Full Text Available Although urolithiasis is common in spinal cord injury patients, it is presumed that the predisposing factors for urinary stones in spinal cord injury patients are immobilization-induced hypercalciuria in the initial period after spinal injury and, in later stages, urine infection by urease-producing micro-organisms, e.g., Proteus sp., which cause struvite stones. We describe a patient who sustained C-7 complete tetraplegia in a road traffic accident in 1970, when he was 16 years old. Left ureterolithotomy was performed in 1971 followed by left nephrectomy in 1972. Probably due to adhesions, this patient developed volvulus of the intestine in 1974. As he had complete tetraplegia, he did not feel pain in the abdomen and there was a delay in the diagnosis of volvulus, which led to ischemia of a large segment of the small bowel. All but 1 ft of jejunum and 1 ft of ileum were resected leaving the large bowel intact. In 1998, suprapubic cystostomy was performed. In 2004, this patient developed calculus in the solitary right kidney. Complete stone clearance was achieved by extracorporeal shock wave lithotripsy. Stone analysis: calcium oxalate 60% and calcium phosphate 40%. Metabolic evaluation revealed hyperoxaluria, hypocitraturia, and hypomagnesiuria. Since this patient had hyperoxaluria, the stool was tested for Oxalobacter formigenes, a specific oxalate-degrading, anerobic bacterium inhabiting the gastrointestinal tracts of humans; absence of this bacterium appears to be a risk factor for development of hyperoxaluria and, subsequently, calcium oxalate kidney stone disease. DNA from the stool was extracted using the QIAamp DNA stool Mini Kit (Qiagen, Chatsworth, CA. The genomic DNA was amplified by polymerase chain reaction using specific primers for oxc gene (developed by Sidhu and associates. The stool sample tested negative for O. formigenes. The patient was prescribed potassium citrate mixture; he was advised to avoid oxalate-rich food, maintain

  15. A novel technique for ultrasound-guided central venous catheterization under short-axis out-of-plane approach: "stepwise flashing with triangulation". (United States)

    Horiuchi, Toshinori; Okuda, Chie; Kurita, Naoko; Yamaguchi, Ayako; Kitagawa, Kazuhiko; Takeda, Masafumi; Sha, Keiichi; Nagahata, Toshihiro


    In ultrasound-guided central venous catheterization, there is no standard technique either for the needle tip visualization or for the adequate needle angle and entry to the skin with short-axis view under out-of-plane technique. In the present study, we propose a novel technique named "stepwise flashing with triangulation", and the efficacy of this technique is assessed. Before and after a didactic session in which the technique was explained, 12 novice residents were asked to position the needle tip on or into the imitation vessels and to avoid deeper penetration by using an agar tissue phantom with ultrasound guidance. "Stepwise flashing" technique was for stepwise visualization of the needle tip, and "triangulation" technique was for adequate needle angle and entry to the skin. After the session, the success rate was increased and a deeper penetration rate was decreased. This technique will help us to facilitate vascular access and to avoid complications in clinical settings.

  16. Bilhemia: a fatal complication following percutaneous placement of a transhepatic inferior vena cava catheter in a child

    Energy Technology Data Exchange (ETDEWEB)

    Sierre, Sergio; Lipsich, Jose; Questa, Horacio [Hospital de Pediatria Prof JP Garrahan, Department of Interventional Radiology, Buenos Aires (Argentina)


    A transhepatic central venous catheter was implanted in a 2-year-old child with a history of multiple venous access procedures and superior and inferior vena cava thrombosis. After 2 weeks, inadvertent dislodgement of the catheter was complicated by a biloma. The biloma was percutaneously drained, but a biliary-venous fistula led to a rapidly progressive and fatal bilhemia. We report this case as an infrequent complication of transhepatic catheterization.

    Full Text Available Background: Malpositions after central venous cannulation are frequently encountered and may need a change in catheter. The incidence of malpositions are varied according to various studies and depend on the experience of the operator performing the cannulation. Aim: To access the incidence of malpositions and related complications associated with landmark-guided central venous cannulation in a 15-bedded medical surgical ICU over a period of three years. Settings and Design: Retrospective analysis of records of all the central venous cannulation done in a 15- bedded medical- surgical ICU over the period of three years (April 2008 to June 2011 were evaluated for the site and side of insertion, number of attempts of puncture, arterial puncture as well as the malpositions on post procedural chest X-ray. The records were also evaluated for the experience of the operator performing cannulation and relationship between experience of operator to malpositions of catheter. Statistical Analysis: Analysis was done using SPSS v 17.0 for Windows. Chi-square test was applied to evaluate the statistical significance. P > 0.05 was significant. Results: Records of 696 cannulations were evaluated. Malpositions occurred in 40 patients. Subclavian vein cannulation resulted in increased malpositions in relation to internal jugular vein cannulation. More common with left sided cannulation. Experience of operator had positive correlation with malpositions and arterial puncture. Arterial puncture was common in 6%, while more than one attempt for cannulation was taken in 100 patients. Conclusion: Incidence of malpositions was low. We conclude that experience of operator improves successful catheterization with lesser number of complications.

    Full Text Available At the final stages of a coronary artery bypass graft operation on a 64-year-old man, an experienced physician attempted to insert an intra-aortic balloon pump into the femoral artery via the Seldinger technique. However, while the balloon pump was being passed over the guide wire, the latter was completely lost.The guide wire should be held at the tip at all times to prevent passage into the vessel. Strict adherence to this rule will prevent guide-wire loss, which is, albeit rare and completely avoidable, a potentially life-threatening complication of central vein or artery catheterization, with reported fatality rates of up to 20% when the whole wire is lost. The literature contains several reports on guide-wire loss during central venous, arterial, and hemodialysis catheterization, but we report for the first time the loss of a guide wire as a rare complication of intra-aortic balloon pump insertion.

  20. Transradial approach in the catheterization laboratory: pros/cons and suggestions for successful implementation. (United States)

    Romagnoli, E; Mann, T; Sciahbasi, A; Pendenza, G; Biondi-Zoccai, G G L; Sangiorgi, G M


    In the last decade the radial access use in the catheterization laboratory has sensibly grown up worldwide. From an initial sporadic use as alternative but challenging vascular approach, radial artery is today utilized by default for percutaneous procedures in many centers. The tangible interest in the transradial approach is also testified by increasing presence of specific sessions in the main interventional meetings and by continuous development of dedicated catheters and ancillary devices by manufacturers. In this review we describe the anatomical characteristics and the technical aspects related to transradial procedure underlying its pros/cons in opposition to femoral access. We also point up practical instructions trying to resolve the main concerns related to an extensive use of radial approach in catheterization laboratory, such as increased operator's discomfort, higher radiation exposure, safety and feasibility for complex high-risk procedures.

    Natany da Costa Ferreira


    Full Text Available ABSTRACT Objective: to identify and review the literature on non-pharmacological strategies used for reducing anxiety in patients receiving cardiac catheterization. Method: this study was an integrative literature review. The research was conducted using the databases LILACS, SciELO, Medline (through BVS and PubMed and Scopus. Studies were analyzed according to their objective, method, instruments used for evaluating patients' anxiety, and the results obtained. Results: the most used strategy for reducing anxiety in patients receiving cardiac catheterization was music therapy. However, no study identifying the most appropriate time for this intervention (before, during and/or after the procedure was found. Other strategies identified in this review were educational videos, massage, and palm therapy. Conclusion: the results found suggest that anxiety can be reduced using non-pharmacological strategies.

    Full Text Available Objective. Out of hospital cardiac arrest (OHCA patients are a critically ill patient population with high mortality. Combining mild therapeutic hypothermia (MTH with early coronary intervention may improve outcomes in this population. The aim of this study was to evaluate predictors of mortality in OHCA patients undergoing MTH with and without cardiac catheterization. Design. A retrospective cohort of OHCA patients who underwent MTH with catheterization (MTH + C and without catheterization (MTH + NC between 2006 and 2011 was analyzed at a single tertiary care centre. Predictors of in-hospital mortality and neurologic outcome were determined. Results. The study population included 176 patients who underwent MTH for OHCA. A total of 66 patients underwent cardiac catheterization (MTH + C and 110 patients did not undergo cardiac catheterization (MTH + NC. Immediate bystander CPR occurred in approximately half of the total population. In the MTH + C and MTH + NC groups, the in-hospital mortality was 48% and 78%, respectively. The only independent predictor of in-hospital mortality for patients with MTH + C, after multivariate analysis, was baseline renal insufficiency (OR = 8.2, 95% CI 1.8–47.1, and p = 0.009. Conclusion. Despite early cardiac catheterization, renal insufficiency and the absence of immediate CPR are potent predictors of death and poor neurologic outcome in patients with OHCA.

  4. Psychophysiological responses to sedative music in patients awaiting cardiac catheterization examination: a randomized controlled trial. (United States)

    Chang, Hui-Kuan; Peng, Tai-Chu; Wang, Ji-Hung; Lai, Hui-Ling


    Cardiovascular diseases are the number 1 cause of death globally. Cardiac catheterization is a key step in the diagnosis and management of cardiovascular diseases. Decreasing the stress of cardiac catheterization is a key factor in improving patients' well-being. The aim of the study was to explore the effect of music on psychophysiological indices in patients awaiting cardiac catheterization examination. Using a 2-group repeated-measures design, 54 subjects aged 47 to 70 years and scheduled for cardiac catheterization examination were recruited. The subjects were randomly assigned to either the music group (27 subjects) or the usual-care group (27 subjects). Subjects in the music group listened to 30 minutes of music, whereas the usual-care group rested quietly, as in routine care. The heart rate (HR), HR variability, and skin temperature (ST) were measured at 7 time points and were recorded by the MP150 recording system (BIOPAC Systems, Inc, Goleta, California). Heart rate variability was analyzed by power spectral analysis: low frequency, high frequency, and ratio of low frequency to high frequency. The state of anxiety was measured at baseline and at time 7. At the end of the study, the subjects' music preference was evaluated using a visual analog scale. Listening to music resulted in a significantly reduced state of anxiety (P = .003). Both the music and quiet rest groups noted the beneficial effects of decreased HR and increased ST (all P music preference, the lower the subjects' perceived anxiety level (P = .05). Our findings provide the necessary scientific support for the use of sedative music and quiet rest as safe and effective interventions against anxiety, as manifested in the subjects' anxiety state, HR, and ST.

  5. Delayed Airway Obstruction after Internal Jugular Venous Catheterization in a Patient with Anticoagulant Therapy

    Directory of Open Access Journals (Sweden)

    Pei-Ju Wu


    Full Text Available Delayed onset of neck hematoma following central venous catheterization without arterial puncture is uncommon. Herein, we present a patient who developed a delayed neck hematoma after repeated attempts at right internal jugular venous puncture and subsequent enoxaparin administration. Progressive airway obstruction occurred on the third day after surgery. Ultrasound examination revealed diffuse hematoma of the right neck, and fibreoptic examination of the airway revealed pharyngeal edema. After emergent surgical removal of the hematoma, the patient was extubated uneventfully.

  6. [Primary angioplasty versus fibrinolysis in patients at a distance from a hospital with a catheterization laboratory]. (United States)

    Aboal, Jaime; Núñez, María; Bosch, Daniel; Tirón, Coloma; Brugada, Ramón; Loma-Osorio, Pablo


    Long distance from a hospital with a catheterization laboratory is associated with a poorer prognosis in patients who undergo primary angioplasty for ST-elevation myocardial infarction (STEMI). An invasive pharmacologic strategy could offer an alternative treatment for these patients. We aimed to establish whether prognosis was better with primary angioplasty or fibrinolysis for reperfusion in cases of STEMI occurring far from a catheterization laboratory. Prospective registry study of patients with STEMI admitted to our cardiology critical care unit. Patients were included over a 5-year period if they received reperfusion therapy and had required transport of more than 50 km to reach a hospital with a catheterization laboratory. We recorded characteristics of the STEMI event, treatment times, and short- and long-term mortality. The data was used for survival analysis. We registered 584 patients; 194 were treated with primary angioplasty and 390 with fibrinolysis. The mean time between first physician contact and balloon insertion was 160 minutes. The mean time between first physician contact and needle insertion for fibrinolysis was 30 minutes. The 2-year mortality rate was higher in patients treated with angioplasty (12.2%) than with those who underwent fibrinolysis (7.0%) ) (P=.04). Survival analysis showed that risk for death was higher in the primary angioplasty group (hazard ratio, 1.97 (95% CI, 0.64-0.95; P=.001). When STEMI occurs more than 50 km from a catheterization laboratory, reperfusion by means of balloon angioplasty delays care considerably and is associated with a higher mortality rate than reperfusion by fibrinolysis.

    Pulmonary hypertension manifests with impaired exercise capacity. Our aim was to investigate whether the mean pulmonary arterial pressure to cardiac output relationship (mPAP/CO) predicts transplant free survival in patients with pulmonary arterial hypertension (PAH) and inoperable chronic thromboembolic pulmonary hypertension (CTEPH). Hemodynamic data according to right heart catheterization in patients with PAH and CTEPH at rest and during supine incremental cycle exercise were analyzed. Tr...

  8. Ureteric catheterization via an ileal conduit: technique and retrieval of a JJ stent

    Energy Technology Data Exchange (ETDEWEB)

    Wah, T.M.; Kellett, M.J. E-mail:


    Retrograde ureteric catheterization of a patient with an ileal conduit is difficult, because guide wires and catheters coil in the conduit. A modified loopogram, using a Foley catheter as a fulcrum through which catheters can be advanced to the ureteric anastomosis, is described. This technique was used to remove a JJ stent, which had been inserted previously across a stricture in one ureter, the stent crossing from one kidney to the other.

  9. SU-E-P-10: Imaging in the Cardiac Catheterization Lab - Technologies and Clinical Applications

    Energy Technology Data Exchange (ETDEWEB)

    Fetterly, K [Mayo Clinic, Rochester, MN (United States)


    Purpose: Diagnosis and treatment of cardiovascular disease in the cardiac catheterization laboratory is often aided by a multitude of imaging technologies. The purpose of this work is to highlight the contributions to patient care offered by the various imaging systems used during cardiovascular interventional procedures. Methods: Imaging technologies used in the cardiac catheterization lab were characterized by their fundamental technology and by the clinical applications for which they are used. Whether the modality is external to the patient, intravascular, or intracavity was specified. Specific clinical procedures for which multiple modalities are routinely used will be highlighted. Results: X-ray imaging modalities include fluoroscopy/angiography and angiography CT. Ultrasound imaging is performed with external, trans-esophageal echocardiography (TEE), and intravascular (IVUS) transducers. Intravascular infrared optical coherence tomography (IVOCT) is used to assess vessel endothelium. Relatively large (>0.5 mm) anatomical structures are imaged with x-ray and ultrasound. IVUS and IVOCT provide high resolution images of vessel walls. Cardiac CT and MRI images are used to plan complex cardiovascular interventions. Advanced applications are used to spatially and temporally merge images from different technologies. Diagnosis and treatment of coronary artery disease frequently utilizes angiography and intra-vascular imaging, and treatment of complex structural heart conditions routinely includes use of multiple imaging modalities. Conclusion: There are several imaging modalities which are routinely used in the cardiac catheterization laboratory to diagnose and treat both coronary artery and structural heart disease. Multiple modalities are frequently used to enhance the quality and safety of procedures. The cardiac catheterization laboratory includes many opportunities for medical physicists to contribute substantially toward advancing patient care.

  10. Low-flow mediated constriction is endothelium-dependent: effects of exercise training after radial artery catheterization. (United States)

    Dawson, Ellen A; Alkarmi, Amr; Thijssen, Dick H J; Rathore, Sudhir; Marsman, Diane E; Cable, N Timothy; Wright, D Jay; Green, Daniel J


    Radial artery catheterization is associated with endothelial denudation and impaired vasodilator function, while postcatheterization exercise training may enhance artery function. The impact of catheterization and subsequent exercise training on low-flow mediated vasoconstriction (L-FMC) has not previously been studied. The aim of this study was to examine whether radial artery L-FMC is impaired by catheterization and consequent endothelial denudation. A further aim was to examine the effect of local handgrip exercise training on radial artery L-FMC and flow-mediated dilation (FMD) after transradial catheterization. Thirty-two subjects undergoing transradial catheterization underwent assessment of L-FMC and FMD in the catheterized and contralateral radial artery before, and the day after, catheterization. A further 18 patients were recruited and randomly assigned to either a 6-week handgrip exercise training program (N=9) or a nonexercise control period (N=9). L-FMC was attenuated 1 day postcatheterization in the catheterized arm (-2.07±0.84 to 0.35±0.83), but unchanged in the noncatheterized arm (-0.93±0.86 to -0.90±0.92; P<0.05). In the training study, both FMD and L-FMC of the catheterized arm were preserved in the exercise group 7 weeks after catheterization (FMD-pre, 6.84±0.79; FMD-post, 6.85±1.16; L-FMC-pre, -2.14±1.42; L-FMC-post, -3.58±1.04%), but reduced in the control group (FMD-pre, 8.27±1.52; FMD-post, 4.66±0.70; P=0.06; L-FMC-pre, -3.26±1.19; L-FMC-post, -1.34±1.27%; P<0.05). Catheterization, and associated endothelial denudation, decreases L-FMC in the radial artery, suggesting that it is endothelium-dependent. Moreover, we demonstrate for the first time that exercise training has beneficial impacts on radial artery vasodilator and constrictor function.

  14. [Incidence of urinary tract infections after cardiac surgery: comparative study accordind to catheterization device]. (United States)

    Hidalgo Fabrellas, I; Rebollo Pavón, M; Planas Canals, M; Barbero Cabezas, M


    Urinary tract infections (UTI) associated with urethral catheterization are the second cause of nosocomial infections in Intensive care units. We confirm a UTI when we get a result of 100,000 CFU/ml with at least one microorganism in a urine culture. Compare and determine the incidence of UTI in cardiac surgery postpoperative patients according to the catheterization device. A prospective, randomized analytical observational study of patients in the immediate cardiac surgery postoperative period. One group was probed with catheter Foley and one was inserted the catheter BIPFoley-Bactiguard® (CBF). The CBF is coated with noble metals (silver, gold and palladium) and biocompatible antimicrobial properties, covering the entire surface of the device and prevents the formation of biofilm, microbial adherence and colonization. 116 cases, 59.5% (69 cases) were negative for UTI and 40.5% (47 cases) were positive. Out of the positive UTI results, 25% were carriers of catheter Foley and 15.5% of CBF. Most common etiologic microorganisms: Escherichia coli 29.8% Klebsiella pneumonia 29.8%, Klebsiella oxytoca 9%. With the data we have observed that patients catheterized BIPfoley-Bactiguard® are infected to a lesser extent than Foley carriers. Copyright © 2013 Elsevier España, S.L.U. y SEEIUC.

  15. Urinary Tract Infections in Spinal Cord Injury Patients Undergoing Intermittent Catheterization Procedures

    Directory of Open Access Journals (Sweden)

    Teresa Kirkland


    Full Text Available A prospective study was organized to assess whether feeding back infection rates to staff performing intermittent catheterization in spinal cord-injured patients would produce a fall in urinary tract infection rates. Over a 12 month period, infection rates for such procedures were reported to unit staff: reporting was combined with educational programs emphasizing aseptic catheterization techniques and the importance ofhandwashing. Overall infection rates for the 12 month period were 13.3 per 1000 days of intermittent catheterization - unchanged from the preceding six months (15.1 per 1000 days by retrospective chart review. Likewise, there was no statistically significant downward trend during the prospective phase of the study. A wide variety of infecting organisms were found, of which Klebsiella species (39%, Escherichia coli (18% and Enterobacter species (17% were most common: most infections were asymptomatic. Patients with complete cord lesions at or above the sixth thoracic spinal cord segment (T6 had a much higher incidence of infection (73% than those with incomplete lesions below T6 (33%.

  16. Hierarchical HMM based learning of navigation primitives for cooperative robotic endovascular catheterization. (United States)

    Rafii-Tari, Hedyeh; Liu, Jindong; Payne, Christopher J; Bicknell, Colin; Yang, Guang-Zhong


    Despite increased use of remote-controlled steerable catheter navigation systems for endovascular intervention, most current designs are based on master configurations which tend to alter natural operator tool interactions. This introduces problems to both ergonomics and shared human-robot control. This paper proposes a novel cooperative robotic catheterization system based on learning-from-demonstration. By encoding the higher-level structure of a catheterization task as a sequence of primitive motions, we demonstrate how to achieve prospective learning for complex tasks whilst incorporating subject-specific variations. A hierarchical Hidden Markov Model is used to model each movement primitive as well as their sequential relationship. This model is applied to generation of motion sequences, recognition of operator input, and prediction of future movements for the robot. The framework is validated by comparing catheter tip motions against the manual approach, showing significant improvements in the quality of catheterization. The results motivate the design of collaborative robotic systems that are intuitive to use, while reducing the cognitive workload of the operator.

  17. Sedation with nitrous oxide compared with no sedation during catheterization for urologic imaging in children

    Energy Technology Data Exchange (ETDEWEB)

    Zier, Judith L. [Children' s Hospitals and Clinics of Minnesota, Pediatric Critical Care, Minneapolis, MN (United States); Children' s Respiratory and Critical Care Specialists, Minneapolis, MN (United States); Kvam, Kathryn A. [University of Michigan Medical School, Ann Arbor, MI (United States); Kurachek, Stephen C. [Children' s Hospitals and Clinics of Minnesota, Pediatric Critical Care, Minneapolis, MN (United States); Finkelstein, Marsha [Children' s Hospitals and Clinics of Minnesota, Center for Care Innovation and Research, Minneapolis, MN (United States)


    Various strategies to mitigate children's distress during voiding cystourethrography (VCUG) have been described. Sedation with nitrous oxide is comparable to that with oral midazolam for VCUG, but a side-by-side comparison of nitrous oxide sedation and routine care is lacking. The effects of sedation/analgesia using 70% nitrous oxide and routine care for VCUG and radionuclide cystography (RNC) were compared. A sample of 204 children 4-18 years of age scheduled for VCUG or RNC with sedation or routine care were enrolled in this prospective study. Nitrous oxide/oxygen (70%/30%) was administered during urethral catheterization to children in the sedated group. The outcomes recorded included observed distress using the Brief Behavioral Distress Score, self-reported pain, and time in department. The study included 204 patients (99 nonsedated, 105 sedated) with a median age of 6.3 years (range 4.0-15.2 years). Distress and pain scores were greater in nonsedated than in sedated patients (P < 0.001). Time in department was longer in the sedated group (90 min vs. 30 min); however, time from entry to catheterization in a non-imaging area accounted for most of the difference. There was no difference in radiologic imaging time. Sedation with nitrous oxide is effective in reducing distress and pain during catheterization for VCUG or RNC in children. (orig.)

  18. Instructional design affects the efficacy of simulation-based training in central venous catheterization. (United States)

    Craft, Christopher; Feldon, David F; Brown, Eric A


    Simulation-based learning is a common educational tool in health care training and frequently involves instructional designs based on Experiential Learning Theory (ELT). However, little research explores the effectiveness and efficiency of different instructional design methodologies appropriate for simulations. The aim of this study was to compare 2 instructional design models, ELT and Guided Experiential Learning (GEL), to determine which is more effective for training the central venous catheterization procedure. Using a quasi-experimental randomized block design, nurse anesthetists completed training under 1 of the 2 instructional design models. Performance was assessed using a checklist of central venous catheterization performance, pass rates, and critical action errors. Participants in the GEL condition performed significantly better than those in the ELT condition on the overall checklist score after controlling for individual practice time (F[1, 29] = 4.021, P = .027, Cohen's d = .71), had higher pass rates (P = .006, Cohen's d = 1.15), and had lower rates of failure due to critical action errors (P = .038, Cohen's d = .81). The GEL model of instructional design is significantly more effective than ELT for simulation-based learning of the central venous catheterization procedure, yielding large differences in effect size.

    Background: Transradial coronary angiography (TRA) has been associated with increased radiation doses. We hypothesized that contemporary image noise reduction technology would reduce radiation doses in the cardiac catheterization laboratory in a typical clinical setting. Methods and results: We performed a single-center, retrospective analysis of 400 consecutive patients who underwent diagnostic and interventional cardiac catheterizations in a predominantly TRA laboratory with traditional fluoroscopy (N = 200) and a new image noise reduction fluoroscopy system (N = 200). The primary endpoint was radiation dose (mGy cm{sup 2}). Secondary endpoints were contrast dose, fluoroscopy times, number of cineangiograms, and radiation dose by operator between the two study periods. Radiation was reduced by 44.7% between the old and new cardiac catheterization laboratory (75.8 mGy cm{sup 2} ± 74.0 vs. 41.9 mGy cm{sup 2} ± 40.7, p < 0.0001). Radiation was reduced for both diagnostic procedures (45.9%, p < 0.0001) and interventional procedures (37.7%, p < 0.0001). There was no statistically significant difference in radiation dose between individual operators (p = 0.84). In multivariate analysis, radiation dose remained significantly decreased with the use of the new system (p < 0.0001) and was associated with weight (p < 0.0001), previous coronary artery bypass grafting (p < 0.0007) and greater than 3 stents used (p < 0.0004). TRA was used in 90% of all cases in both periods. Compared with a transfemoral approach (TFA), TRA was not associated with higher radiation doses (p = 0.20). Conclusions: Image noise reduction technology significantly reduces radiation dose in a contemporary radial-first cardiac catheterization clinical practice. - Highlights: • Radial arterial access has been associated with higher doses compared to femoral access. • In a radial-first cardiac catheterization laboratory (90% radial) we examined radiation doses reduction with a contemporary image

  2. Intermittent catheterization acceptance test (I-CAT): A tool to evaluate the global acceptance to practice clean intermittent self-catheterization. (United States)

    Guinet-Lacoste, Amandine; Kerdraon, Jacques; Rousseau, Alexandra; Gallien, Philippe; Previnaire, Jean-Gabriel; Perrouin-Verbe, Brigitte; Amarenco, Gérard


    In certain cases, a patient's anxiety, fear, or misconceptions can represent significant obstacles to the learning of Clean Intermittent Self Catheterization (CISC), and little is known about these psychological barriers. The aim of the present study is thus to construct and validate an "Intermittent Catheterization Acceptance Test (I-CAT)" to evaluate the psychological acceptance of CISC. A study was carried out in nine neuro-rehabilitation and urology departments in French university hospitals. Fifty-five items were identified, following a comprehensive review of the literature and cognitive debriefing interviews with patients. Following an initial expert panel meeting (EPM) with a French-speaking neuro-urology study group (GENULF), this list was refined and reduced to a draft I-CAT comprising 34 items. The face validity of the draft I-CAT was determined, and the results were then analyzed in a second EPM, leading to the elaboration of a second version of the I-CAT (23 items, 5 dimensions). Psychometric validation of this second version was established from a longitudinal, non-randomized study involving 201 neurological and non-neurological patients. Linguistic validation was carried out in English. Following the construct validity analyses, several items were deleted due to item overlap, ceiling effects, or poor content validity and 14 items were retained. Confirmatory factor analysis shows that this version has 2 dimensions. Cronbach's alpha was 0.93. The ICC demonstrated good test-retest reliability and satisfactory responsiveness. The upstream identification and solving of potential psychological barriers prior to the learning of CISC could improve patients' acceptance of this procedure. © 2017 Wiley Periodicals, Inc.

    PurposeTo prospectively assess discontinuation of indwelling bladder catheterization (IBC) and relief of lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) following prostate artery embolization (PAE) in poor surgical candidates.MethodsPatients ineligible for surgical intervention were offered PAE after at least 1 month of IBC for management of urinary retention secondary to BPH; exclusion criteria for PAE included eligibility for surgery, active bladder cancer or known prostate cancer. Embolization technical and clinical success were defined as bilateral prostate embolization and removal of IBC, respectively. Patients were followed for at least 6 months and evaluated for International Prostate Symptom Score, quality of life, prostate size and uroflowmetric parameters.ResultsA total of 43 patients were enrolled; bilateral embolization was performed in 33 (76.7%), unilateral embolization was performed in 8 (18.6%), and two patients could not be embolized due to tortuous and atherosclerotic pelvic vasculature (4.7%). Among the patients who were embolized, mean prostate size decreased from 75.6 ± 33.2 to 63.0 ± 23.2 g (sign rank p = 0.0001, mean reduction of 19.6 ± 17.3%), and IBC removal was achieved in 33 patients (80.5%). Clavien II complications were reported in nine patients (21.9%) and included urinary tract infection (three patients, 7.3%) and recurrent acute urinary retention (six patients, 14.6%). Nine patients (22.0%) experienced post-embolization syndrome.ConclusionsPAE is a safe and feasible for the relief of LUTS and IBC in highly comorbid patients without surgical treatment options.

    In order to determine the effect of the manner of dress by personnel and observers on cardiac catheterization-related infections, a retrospective survey was undertaken of 107,203 catheterization procedures done during the calendar year prior to this survey. An analysis of 55,976 cutdowns and 53,578 percutaneous procedures was performed (some subjects had both procedures performed). A total of 379 infections in 109,554 entrance sites were reported for an overall incidence of infection of 0.35%. There were 33 infections at the percutaneous site (incidence = 0.06%) and 346 at the cutdown site (incidence = 0.62%). The manner of dress of personnel not involved with catheter manipulation and of the observers had no relationship to the incidence of infection when the percutaneous technique was used. When cutdowns were performed, there was a lower incidence of infection in those laboratories where all personnel and observers were required to wear a mask, cap, and gown (17,311 cutdowns, 83 infections, 0.48% infection rate) than in those laboratories where none of these was required (15,170 cutdowns, 109 infections, 0.72% infection rate) (P less than 0.025). Laboratories which did 150 or less cutdowns/year had more infections than those laboratories performing more than 150/year (P less than 0.0001). Our data suggest that the risk of infection from cardiac catheterization is more closely correlated with the volume of studies done in the laboratory than in the manner of dress of the laboratory personnel and visitors in the laboratory. However, the wearing of full "sanitary clothing" will help decrease the infection rate in cutdowns.

    Full Text Available Background: The goals for sedation in pediatric patients scheduled to undergo cardiac catheterization include immobility, analgesia, cardiovascular and respiratory stability. We investigated the effects of Propofol and Ketamine on hemodynamic, respiratory status, sedation level, pain score and recovery period in pediatric patients undergoing cardiac catheterization. Methods: We preformed a randomized clinical trial study on 40 pediatric patients. The patients were randomly assigned to two groups, so that 20 patients received Ketamine and 20 patients received Propofol. In all patients, sedation was started with Midazolam (0.03mg/kg, then followed by Propofol in the first group and Ketamine in the second one. The hemodynamic responses, respiratory parameters, recovery characteristics (Ramsey scale, pain score VAS and relevant adverse effects of the two groups were recorded. Data was analyzed using Paired T Test, ANOVA and Stearman correlation coefficient. Results: Five patients in the Propofol group andon patients in the Ketamine group experienced a transient decrease in mean systolic blood pressure greater than 10% of baseline(p=0.034. Time to full recovery (mean ± SD was not significantly different in the Propofol group and Ketamine group (1.8 min vs. 2.9 min, P > 0.05. Pain scores were significantly different in both groups (P= 0.010. Patients’ heart rates were significantly higher in Ketamine group(P=0.029. No significant difference in respiratory rate was recorded in both groups(p›0.05. Conclusion: Both Ketamine and Propofol are useful and safe in pediatric patients undergoing cardiac catheterization but it seems that it is better to use Propofol in stable hemodynamic pediatric patients under continuous blood pressure monitoring.

  6. Medicolegal characteristics of cardiac catheterization litigation in the United States, 1985 to 2009. (United States)

    Kim, Candice; Vidovich, Mladen I


    There are few assessments of patterns of medicolegal cases involving cardiac catheterizations. This descriptive study reviews the patterns of liability and medical outcomes involving cardiac catheterization litigation from the LexisNexis Academic database and the Physician Insurers Association of America registry. From 1985 to 2009, the Physician Insurers Association of America registry documented 1,361 closed coronary angiography claims. The cardiovascular disease specialty was involved in 699 with other specialties involved in the remaining cases. Of the 1,361 closed claims, 301 (22%) resulted in payments to the plaintiff (average indemnity of $230,987). The most common alleged error was for improper performance (35.4%; average indemnity of $255,542). The alleged error with the highest average indemnity of $270,916 was errors in diagnosis. Not performing an indicated procedure had the highest ratio of paid to closed claims (41%) with an average indemnity of $246,988. In regard to the severity of injury, death was the most common outcome (44%). The highest ratio of paid to total closed claims (43%) was for grave injuries (highest average indemnity of $555,625). Of the 116 LexisNexis cases, litigation against physicians occurred in 90.5% of cases with judgments in favor of the patients in 29.5%. When death was the outcome (31% of cases), physicians were highly likely to be sued (97%) and the judgment was more likely in the plaintiffs' favor (44%). In conclusion, in litigation related to cardiac catheterizations, most cases are due to medical malpractice and physicians are sued in a high percentage of cases. Cardiologists should recognize these patterns of litigation as these may impact and improve processes of care. Published by Elsevier Inc.

    International audience; We present an initial evaluation of a robotic arm for positioning a 3D echo probe during cardiac catheterization procedures. By tracking the robotic arm, X-ray table and X-ray C-arm, we are able to register the 3D echo images with live 2D X-ray images. In addition, we can also use tracking data from the robotic arm combined with system calibrations to create extended field of view 3D echo images. Both these features can be used for roadmapping to guide cardiac catheter...

  9. Cardiac Arrest in a Heart Transplant Patient Receiving Dexmedetomidine During Cardiac Catheterization. (United States)

    Schwartz, Lawrence Israel; Miyamoto, Shelley D; Stenquist, Scott; Twite, Mark David


    Dexmedetomidine is an α-2 agonist with a sedative and cardiopulmonary profile that makes it an attractive anesthetic in pediatric cardiac patients. Cardiac transplant patients may suffer from acute cellular rejection of the cardiac conduction system and, therefore, are at an increased risk of the electrophysiological effect of dexmedetomidine. We present such a patient who had a cardiac arrest while receiving dexmedetomidine during cardiac catheterization. Because acute cellular rejection of the cardiac conduction system is difficult to diagnose, dexmedetomidine should be used with caution in pediatric heart transplant patients. © The Author(s) 2015.

  10. "Snare-Ride": A Bailout Technique to Catheterize Target Vessels With Unfriendly Anatomy in Branched Endovascular Aortic Repair. (United States)

    Ferreira, Marcelo; Katsargyris, Athanasios; Rodrigues, Eduardo; Ferreira, Diego; Cunha, Rodrigo; Bicalho, Guilherme; Oderich, Gustavo; Verhoeven, Eric L G


    To describe a novel endovascular bailout technique for successful completion of target vessel stenting during branched stent-graft repair of thoracoabdominal aortic aneurysms (TAAA) after encountering difficulties with standard catheterization techniques. Technical difficulties when using fenestrated and branched grafts should be expected, especially in difficult anatomy or when an off-the-shelf device (eg, standard 4-branch device) is used that does not perfectly "match" the anatomy. The "snare-ride technique" facilitates antegrade transaxillary side branch catheterization and stent placement during TAAA branched grafting using a snare via a transfemoral approach. The branch of the graft is catheterized from an axillary access. The respective target vessel is then catheterized via a femoral access. An Indy snare is advanced over the transfemoral wire and positioned near the entrance of the target vessel. The transaxillary wire inside the branch of the graft is then advanced, snared, and pushed inside the target vessel with the snare. The procedure is thereafter continued with antegrade bridging of the target vessel in routine fashion. The snare-ride technique can be a useful maneuver to catheterize target vessels with difficult anatomy in TAAA branched stent-graft repair. Early experience shows safety and feasibility.

    da Gama, A Dinis; Martins, Carlos; Pedro, L Mendes; Evangelista, Ana; Almeida, Paulo; Gimenez, J Luis; Rodriguez, J Maria


    In this paper the clinical condition of two male patients, aged 58 and 65 years are presented, after being admitted as a consequence of a rare complication of an inflammatory aneurysm of the abdominal aorta, which is an ureteral compression, with hydronephrosis, anuria and acute renal failure. After having an urgent haemodialysis session, the etiology of the process was diagnosed by echography and abdominal CT-scans, followed by ureteral catheterization, restoration of diuresis and normalization of renal function. Conventional surgery was performed later, in elective conditions, and the post operative course was normal, without complications. The main features of this clinical entity, its diagnosis and multidisciplinary management are presented and discussed.

In vitro biofilm formation ability was determined by microliter tissue culture plates. All clinical isolates were examined for determination the ica locus by using PCR method.Results: Ninety seven (62% of the samples were bacterial positive. Positive samples were significantly higher in LTC (95% than STC (61% patients. Escherichia coli were the predominant microorganism (32% followed by Klebsiella pneumoniae (15%, Pseudomonas aeroginosa (11%, Enterococcus faecalis (9.2%. From the total isolates, 42% were resistant to 5 or more antibiotics. Furthermore, high prevalence ofresistance amongst all isolates to ciprofloxacin (49% was observed.Conclusions: Diverse bacterial clones were observed for LTC and STC patients. Overall, the results suggested that catheterization could be a major source for growth and dissemination of highly resistant and diverse bacterial species in the hospitals.

  16. [Cerebral vascular accidents after cardiac catheterization in patients with anamnesis of stroke]. (United States)

    Zhang, Hua; Zhang, Zhuo


    To investigate the risk factors of relapse of cerebral vascular accident (CVA) after cardiac catheterization (CC) in patients with anamnesis stroke. The clinical data of 892 patients with anamnesis stroke who received cardiac catheterization (CC) from Jan. 2002 to Oct. 2006, 555 males and 337 females, aged 61 +/- 10, were analyzed retrospectively. 101 of the 892 patients (11.32%) suffered from CVA during the procedure of CC or within 24 hours after the operation, including 33 cases of transient ischemic attack (TIA), 64 cases of cerebral infarction (CI) and 4 cases of cerebral hemorrhage (CH). Logistic regression analysis showed that the risk factors of relapse of CVA after CC included male gender (OR = 0.308, 95% CI = 0.141 - 0.674), alcohol consumption (OR = 0.319, 95% CI = 0.128 - 0.797), hyperlipidemia (OR = 3.676, 95% CI = 1.94 - 6.950), peripheral vascular diseases (OR = 7.419, 95% CI = 2.477 - 22.219), and number of cardiac vascular diseases (OR = 1.809, 95% CI = 1.284 - 2.548). The patients undergoing percutaneous transluminal coronary angioplasty (PTCA) and stenting were much more liable to CVA compared with the other patients. The risk factors of relapse of CVA after CC include male gender, alcohol consumption, hyperlipidemia, peripheral vascular diseases, number of cardiac vascular diseases, and the procedures of PTCA and stenting.

  17. Home screening for bacteriuria in children with spina bifida and clean intermittent catheterization. (United States)

    Significant bacteriuria (SBU) and urinary tract infections (UTIs) are common in patients with spina bifida and neuropathic detrusor sphincter dysfunction. Laboratory agar plated culture is the gold standard to establish SBU. It has the disadvantage of diagnostic and subsequent therapeutic delay. Leukocyte esterase tests (LETs) and dip slides proved to be useful in the general populations to exclude SBU and UTI. The aim of this study was to evaluate the reliability of LET and dip slide in children with spina bifida without symptoms of UTI. The reliability in children with asymptomatic SBU was not studied before. In one hundred and twelve children with spina bifida on clean intermittent catheterization LETs and dip slides were compared with laboratory cultures. Both tests and agar plated cultures were performed on catheterized urine samples. The hypothesis was that the home tests are as accurate as laboratory cultures. A SBU was found in 45 (40%) of the 112 laboratory cultures. A negative LET excluded SBU (negative predictive value 96%), while a positive LET had a positive predictive value of 72%. The false positive rate was 28%. Dip slide determination of bacterial growth had no added value, other than serving as transport medium. In spina bifida children, leukocyte esterase testing can be used to exclude significant bacteriuria at home, while dip slide tests have no added value to diagnose or exclude significant bacteriuria.

  19. Bladder pressure monitoring during intermittent catheterization: a comparison of gauges and methods. (United States)

    Ferguson, Corri L; Walter, James S; Lucero, Yuonne; Wheeler, John S; Damaser, Margot S


    We previously have investigated a technique for serial bladder pressure measurements in patients with spinal cord injury (SCI) using intermittent catheterization. In the current study, we compared an FDA-approved digital gauge with the previously studied analog gauge and studied the effects of hydrostatic pressure differences. Either a digital or an analog pressure gauge was attached to each subject's catheter just before bladder catheterization. Both immediate and stable pressures were recorded. The bladder was then drained until nearly empty and pressure was again recorded (almost empty bladder pressure). Detrusor pressure was estimated as full minus almost empty bladder pressure. Bladder pressures greater than 40 cm H2O were presumed to represent bladder contractions. To investigate the effects of hydrostatic pressure, additional measurements, adjusting the level of the air-urine meniscus, were obtained in three subjects. Recordings were made from nine SCI subjects using both gauges. Estimates of detrusor pressure, with and without bladder contractions, and associated bladder volumes, were not significantly different between digital and analog gauges. In the absence of bladder contractions, detrusor pressure with the meniscus at the end of the catheter (5 +/- 1 cm H2O) was significantly lower than that recorded with no adjustment of the urine meniscus (12 +/- 1 cm H2O). Standardizing measurement techniques to equalize hydrostatic pressures should facilitate reliable estimates of detrusor pressure. Frequent monitoring of bladder pressure using this technique may assist with the urological care of SCI patients.

    Portal biliopathy is the complex of abnormalities of extrahepatic and intrahepatic bile ducts, cystic duct, and gallbladder, arising as a result of extrahepatic portal vein obstruction and noncirrhotic portal fibrosis, which can be caused by coagulopathies, tumors, inflammation, postoperative complications, dehydration, and neonatal umbilical vein catheterization. We report a case of a 55-year-old male patient with the history of pancreatic cancer and cholecystoenteric anastomosis presenting with gastrointestinal bleeding from gallbladder varices via the anastomosis.

    Hakala, Tapio; Vironen, Jaana; Karlsson, Sari; Pajarinen, Jarkko; Hirvensalo, Eero; Paajanen, Hannu


    In Finland, all healthcare personnel must be insured against causing patient injury. The Patient Insurance Centre (PIC) pays compensation in all cases of malpractice and in some cases of infection or other surgical complications. This study aimed to analyze all complaints relating to fatal surgical or other procedure-related errors in Finland during 2006-2010. In total, 126 patients fulfilled the inclusion criteria. Details of patient care and decisions made by the PIC were reviewed, and the total national number of surgical procedures for the study period was obtained from the National Hospital Discharge Registry. Of the 94 patients who underwent surgery, most fatal surgical complications involved orthopedic or gastrointestinal surgery. Non-surgical procedures with fatal complications included deliveries (N = 10), upper gastrointestinal endoscopy or nasogastric tube insertion (N = 8), suprapubic catheter insertion (N = 4), lower intestinal endoscopy (N = 5), coronary angiogram (N = 1), pacemaker fitting (N = 1), percutaneous drainage of a hepatic abscess (N = 1), and chest tube insertion (N = 2). In 42 (33.3 %) cases, patient injury resulted from errors made during the procedure, including 24 technical errors and 15 errors of judgment. There were 19 (15.2 %) cases of inappropriate pre-operative assessment, 28 (22.4 %) errors made in postoperative follow-up, 23 (18.4 %) cases of fatal infection, and 11 (8.8 %) fatal complications not linked to treatment errors. Fatal surgical and procedure-related complications are rare in Finland. Complications are usually the result of errors of judgment, technical errors, and infections.

    Full Text Available Plasma soluble CD40 ligand (sCD40L is mainly generated by cleavage of CD40L from the surface of activated platelets, and therefore considered a platelet activation marker. Although the predictive value of sCD40L for ischemic events has been demonstrated in patients with acute coronary syndromes (ACS, studies on the association of sCD40L with cardiovascular outcomes in lower risk populations yielded heterogeneous results. We therefore sought to investigate factors influencing sCD40L levels, and the predictive value of sCD40L for long-term ischemic events in unselected, aspirin-treated patients undergoing cardiac catheterization. sCD40L was determined by a commercially available enzyme-linked immunosorbent assay in 682 consecutive patients undergoing cardiac catheterization. Two-year follow-up data were obtained from 562 patients. Dual antiplatelet therapy with aspirin and clopidogrel was associated with significantly lower levels of sCD40L and lower platelet surface expressions of P-selectin and activated GPIIb/IIIa compared to aspirin monotherapy (all p≤0.01. Hypertension was linked to lower plasma concentrations of sCD40L, whereas female sex, increasing high-sensitivity C-reactive protein, and hematocrit were associated with higher sCD40L concentrations (all p<0.05. sCD40L levels were similar in patients without and with the primary endpoint in the overall study population (p = 0.4. Likewise, sCD40L levels did not differ significantly between patients without and with the secondary endpoints (both p≥0.4. Similar results were obtained when only patients with angiographically-proven coronary artery disease (n = 459, stent implantation (n = 205 or ACS (n = 125 were analyzed. The adjustment for differences in patient characteristics by multivariate regression analyses did not change the results. ROC curve analyses did not reveal cut-off values for sCD40L for the prediction of the primary or secondary endpoints. In conclusion, plasma sCD40L

    Poretti, F.; Rosen, T.; Koerner, B.; Vorwerk, D. [Inst. fuer diagnostische und interventionelle Radiologie, Klinikum Ingolstadt (Germany)


    Purpose: until now, no mechanical closure devices were available to achieve fast and secure hemostasis for vessel closure after catheterization of small arterial vessels. Material and methods: eighty patients were randomized to evaluate the effect on hemostasis by use of a chitosan pad (Chito-Seal, Abbott Vascular Devices, Galway/Ireland) in comparison to manual compression after diagnostic transbrachial arterial catheterization. Hemostasis after three minutes and one hour as well as local development of a hematoma after one and twenty-four hours were assessed. Results: the use of chitosan pads significantly decreased the bleeding time in the first three minutes after manual compression time (p < 0.01). Significant decrease in bleeding risk at three minutes by use of the chitosan closure pads was also found in subgroups of patients with hypertension (p < 0.001) or diabetes (p < 0.01) and also in patients under anticoagulation therapy (p < 0.01). In addition, long-term protection from bleeding complications such as the risk of hematoma was decreased by the use of chitosan closure pads one hour (p < 0.01) or twenty-four hours (p < 0.001) after catheter removal. Conclusion: the use of an intravascular anchor or suture system is not safely applicable in these vessels due to the small diameter of the brachial artery. Our results document a significant improvement in hemostasis by using chitosan pads in these cases. (orig.)

  5. Effect of music therapy with emotional-approach coping on preprocedural anxiety in cardiac catheterization: a randomized controlled trial. (United States)

    Ghetti, Claire M


    Individuals undergoing cardiac catheterization are likely to experience elevated anxiety periprocedurally, with highest anxiety levels occurring immediately prior to the procedure. Elevated anxiety has the potential to negatively impact these individuals psychologically and physiologically in ways that may influence the subsequent procedure. This study evaluated the use of music therapy, with a specific emphasis on emotional-approach coping, immediately prior to cardiac catheterization to impact periprocedural outcomes. The randomized, pretest/posttest control group design consisted of two experimental groups--the Music Therapy with Emotional-Approach Coping group [MT/EAC] (n = 13), and a talk-based Emotional-Approach Coping group (n = 14), compared with a standard care Control group (n = 10). MT/EAC led to improved positive affective states in adults awaiting elective cardiac catheterization, whereas a talk-based emphasis on emotional-approach coping or standard care did not. All groups demonstrated a significant overall decrease in negative affect. The MT/EAC group demonstrated a statistically significant, but not clinically significant, increase in systolic blood pressure most likely due to active engagement in music making. The MT/EAC group trended toward shortest procedure length and least amount of anxiolytic required during the procedure, while the EAC group trended toward least amount of analgesic required during the procedure, but these differences were not statistically significant. Actively engaging in a session of music therapy with an emphasis on emotional-approach coping can improve the well-being of adults awaiting cardiac catheterization procedures.

  7. Ultrasonography-guided radial artery catheterization is superior compared with the traditional palpation technique: a prospective, randomized, blinded, crossover study. (United States)

    Hansen, M A; Juhl-Olsen, P; Thorn, S; Frederiksen, C A; Sloth, E


    Radial artery catheterization is gaining popularity for diagnostic and interventional procedures. Palpation technique is widely used for the procedure, but ultrasonography has been shown to increase catheterization success. A recently described ultrasonography technique is termed 'dynamic needle tip positioning'. We aimed to compare the traditional palpation technique and dynamic needle tip positioning technique in regard to clinically relevant end points. The study was conducted as a randomized, patient-blinded, crossover study. Patients underwent bilateral radial artery catheterization using both techniques. The primary end point of the study was needle manipulation time. Additional end points were (1) the number of skin perforations, (2) the number of attempts targeting the vessel, (3) the number of catheters placed in first attempt and (4) the number of catheters used. Forty patients were analyzed. There was no significant difference in median needle manipulation time [32 s (range 11-96 s) vs. 39 s (range 9-575 s), P = 0.525], although the variance was lower in the dynamic needle tip positioning group (P palpation technique group, a higher number of skin perforations (57 vs. 40, P = 0.003), catheters (46 vs. 40, P = 0.025) and attempts targeting the vessel (104 vs. 43, P technique for radial artery catheterization significantly improves clinically relevant aspects of the procedure. © 2014 The Acta Anaesthesiologica Scandinavica Foundation.

  8. Towards Robot-Assisted Echocardiographic Monitoring in Catheterization Laboratories : Usability-Centered Manipulator for Transesophageal Echocardiography. (United States)

    Pahl, Christina; Ebelt, Henning; Sayahkarajy, Mostafa; Supriyanto, Eko; Soesanto, Amiliana


    This paper proposes a robotic Transesophageal Echocardiography (TOE) system concept for Catheterization Laboratories. Cardiovascular disease causes one third of all global mortality. TOE is utilized to assess cardiovascular structures and monitor cardiac function during diagnostic procedures and catheter-based structural interventions. However, the operation of TOE underlies various conditions that may cause a negative impact on performance, the health of the cardiac sonographer and patient safety. These factors have been conflated and evince the potential of robot-assisted TOE. Hence, a careful integration of clinical experience and Systems Engineering methods was used to develop a concept and physical model for TOE manipulation. The motion of different actuators of the fabricated motorized system has been tested. It is concluded that the developed medical system, counteracting conflated disadvantages, represents a progressive approach for cardiac healthcare.

  10. Cu-blood flow model through a catheterized mild stenotic artery with a thrombosis. (United States)

    Elnaqeeb, Thanaa; Mekheimer, Khaled S; Alghamdi, Felwah


    Copper nanoparticles blood flow analysis through a catheterized mild stenotic artery with a thrombosis is presented. The system of coupled governing equations are prescribed and then simplified under mild stenosis assumptions. The governing equations are solved exactly, and then expressions for temperature, axial velocity, stream function, wall shear stress and resistance impedance are obtained generally for metallic nanoparticles blood flow.

  11. Mycotic Saccular Abdominal Aortic Aneurysm in an Infant after Cardiac Catheterization: A Case Report. (United States)

    Benrashid, Ehsan; McCoy, Christopher C; Rice, Henry E; Shortell, Cynthia K; Cox, Mitchell W


    Abdominal aortic aneurysms (AAAs) are a rare entity in the pediatric population. Children with mycotic (infectious) AAA in particular are at risk of life-threatening rupture due to their rapid expansion coupled with aortic wall thinning and deterioration. Here, we present the case of a 10-month-old infant with prior 2-staged repair for hypoplastic left heart syndrome that was incidentally discovered to have a mycotic AAA on abdominal ultrasound (US) for evaluation of renovascular hypertension. Before the time of evaluation with US, the infant had developed methicillin-resistant Staphylococcus aureus bacteremia 3 days after cardiac catheterization with percutaneous thoracic aortic balloon angioplasty. She had normal aortic contours on contrasted computed tomography scan of the abdomen approximately 2 weeks before the aforementioned US evaluation. This infant subsequently underwent open aneurysmorrhaphy with cryopreserved vein patch angioplasty with resolution of her aneurysmal segment. Copyright © 2015 Elsevier Inc. All rights reserved.

  18. Comparison of Magnetic Resonance Imaging and Cardiac Catheterization in Patients with Suspected Severe Aortic Stenosis

    Directory of Open Access Journals (Sweden)

    Miroslav Solař


    Full Text Available Objective. Magnetic resonance imaging (MRI is a novel technique used in the assessment of aortic stenosis. The aim of the study was to compare MRI and cardiac catheterization (CAT that is still considered to be a “golden standard” in this indication. Methods. Thirty-four patients referred to CAT for the evaluation of aortic stenosis were enrolled into the study. CAT was performed according to the standardized protocol. Cardiac output was measured by thermodilution and mean aortic gradient was determined using simultaneous blood pressure measurement in aorta and left ventricle. MRI was performed within the period of 3 weeks after CAT. True FISP sequence with retrospective ECG gating was used for the imaging of the aortic valve orifice. Planimetry of the aortic valve area (AVA was performed at the time of maximal opening of the valve during systole. Results. MRI enabled the measurement of AVA in all patients enrolled. Mean AVA defined by CAT and MRI were 0,97 (±0,41 cm2 and 1,38 (±0,55 cm2, respectively. The correlation between the evaluated methods was statistically significant (p=0,003, but not very strong (r=0,43. The comparison of both methods in the identification of the severe aortic stenosis was characterized by kappa value of 0,331. Conclusion. Our study shows low agreement between cardiac catheterization and magnetic resonance imaging in the assessment of aortic stenosis. However, MRI might have a role in the diagnostic algorithm in patients with suspected severe aortic stenosis and moderate mean aortic gradient or concomitant valvular insufficiency.

  19. Controlling urinary tract infections associated with intermittent bladder catheterization in geriatric hospitals. (United States)

    Girard, R; Gaujard, S; Pergay, V; Pornon, P; Martin Gaujard, G; Vieux, C; Bourguignon, L


    Controlling urinary tract infections (UTIs) associated with intermittent catheterization in geriatric patients. After a local epidemiological study identified high rates of UTI, a multi-disciplinary working group implemented and evaluated corrective measures. In 2009, a one-month prospective study measured the incidence of UTI, controlled for risk factors and exposure, in six geriatric hospitals. In 2010, a self-administered questionnaire on practices was administered to physicians and nurses working in these geriatric units. In 2011, the working group developed a multi-modal programme to: improve understanding of micturition, measurement of bladder volume and indications for catheter drainage; limit available medical devices; and improve prescription and traceability procedures. Detailed training was provided to all personnel on all sites. The epidemiological study was repeated in 2012 to assess the impact of the programme. Over 1500 patients were included in the 2009 study. The incidence of acquired infection was 4.8%. The infection rate was higher in patients with intermittent catheters than in patients with indwelling catheters (29.7 vs 9.9 UTI per 100 patients, P = 0.1013) which contradicts the literature. In 2010, the 269 responses to the questionnaire showed that staff did not consider catheterization to place patients at risk of infection, staff had poor knowledge of the recommended indications and techniques, and the equipment varied widely between units. Following implementation of the programme, the study was repeated in 2012 with over 1500 patients. The frequency of UTI in patients with intermittent catheters fell to rates in the published literature. Multi-modal programmes are an effective means to control UTI.

  20. Predictors of Medical Management in Patients Undergoing Elective Cardiac Catheterization for Chronic Ischemic Heart Disease. (United States)

    Atreya, Auras R; Sivalingam, Senthil K; Arora, Sonali; Kashef, Mohammad Amin; Fitzgerald, Janice; Visintainer, Paul; Lotfi, Amir; Rothberg, Michael B


    Compared with medical therapy, percutaneous coronary intervention (PCI) does not reduce mortality or myocardial infarction in patients with stable angina. Therefore, PCI should be guided by refractory anginal symptoms and not just lesion characteristics. We hypothesized that angiographic lesion characteristics and stress test results would have a greater role in the decision to proceed with PCI than would symptom severity. We performed a retrospective cohort study of patients undergoing elective cardiac catheterization and possible PCI at an academic medical center. Anginal symptoms, optimal medical therapy, antianginal therapy, stress test results, and angiographic lesions (including American College of Cardiology/American Heart Association [ACC/AHA] lesion type) were analyzed. Logistic regression was used to determine predictors of medical management among patients not referred for coronary artery bypass surgery. Of the 207 patients with obstructive lesions amenable to PCI, 163 underwent PCI and 44 were referred to medical therapy. In the multivariable logistic model, the following variables were associated with medical management: advancing age (odds ratio [OR] per 1 year: 0.94, 95% confidence interval [CI]: 0.91-0.98), chronic kidney disease (OR: 0.23, 95% CI: 0.06-0.95), distal location (OR: 0.21, 95% CI: 0.09-0.48), and ACC/AHA type C lesion (OR: 0.08, 95% CI: 0.03-0.22). There was no association with sex, race, symptoms, optimal medical therapy, maximal antianginal therapy, referral status, or type of interventional cardiologist (academic vs private practice). For patients undergoing cardiac catheterization for stable angina, the decision to proceed to PCI vs medical management appears to depend largely on patient and angiographic characteristics, but not on symptoms or ischemia. Distal and high-risk lesions (ACC/AHA type C) are more often referred for medical therapy. © 2016 Wiley Periodicals, Inc.

    Epidemiological studies have shown associations between air temperature and cardiovascular health outcomes. Metabolic dysregulation might also play a role in the development of cardiovascular disease. To investigate short-term temperature effects on metabolites related to cardiovascular disease. Concentrations of 45 acylcarnitines, 15 amino acids, ketone bodies and total free fatty acids were available in 2869 participants from the CATHeterization GENetics cohort recruited at the Duke University Cardiac Catheterization Clinic (Durham, NC) between 2001 and 2007. Ten metabolites were selected based on quality criteria and cluster analysis. Daily averages of meteorological variables were obtained from the North American Regional Reanalysis project. Immediate, lagged, and cumulative temperature effects on metabolite concentrations were analyzed using (piecewise) linear regression models. Linear temperature effects were found for glycine, C16-OH:C14:1-DC, and aspartic acid/asparagine. A 5°C increase in temperature was associated with a 1.8% [95%-confidence interval: 0.3%; 3.3%] increase in glycine (5-day average), a 3.2% [0.1%; 6.3%] increase in C16-OH:C14:1-DC (lag of four days), and a -1.4% [-2.4%; -0.3%] decrease in aspartic acid/asparagine (lag of two days). Non-linear temperature effects were observed for alanine and total ketone bodies with breakpoint of 4°C and 20°C, respectively. Both a 5°C decrease in temperature on colder days (air temperature on metabolites several of which are reported to be involved in cardiovascular disease. Our findings might help to understand the link between air temperature and cardiovascular disease. Copyright © 2016 Elsevier Inc. All rights reserved.

    Agarwal, Shikhar; Gallo, Justin J; Parashar, Akhil; Agarwal, Kanika K; Ellis, Stephen G; Khot, Umesh N; Spooner, Robin; Murat Tuzcu, Emin; Kapadia, Samir R


    Operational inefficiencies are ubiquitous in several healthcare processes. To improve the operational efficiency of our catheterization laboratory (Cath Lab), we implemented a lean six sigma process improvement initiative, starting in June 2010. We aimed to study the impact of lean six sigma implementation on improving the efficiency and the patient throughput in our Cath Lab. All elective and urgent cardiac catheterization procedures including diagnostic coronary angiography, percutaneous coronary interventions, structural interventions and peripheral interventions performed between June 2009 and December 2012 were included in the study. Performance metrics utilized for analysis included turn-time, physician downtime, on-time patient arrival, on-time physician arrival, on-time start and manual sheath-pulls inside the Cath Lab. After implementation of lean six sigma in the Cath Lab, we observed a significant improvement in turn-time, physician downtime, on-time patient arrival, on-time physician arrival, on-time start as well as sheath-pulls inside the Cath Lab. The percentage of cases with optimal turn-time increased from 43.6% in 2009 to 56.6% in 2012 (p-trendsix sigma, on improving and sustaining efficiency of our Cath Lab operation. After the successful implementation of this continuous quality improvement initiative, there was a significant improvement in the selected performance metrics namely turn-time, physician downtime, on-time patient arrival, on-time physician arrival, on-time start as well as sheath-pulls inside the Cath Lab.

  3. What is the true catheterization rate after intravesical onabotulinumtoxinA injection? (United States)

    Patel, Devin N; Jamnagerwalla, Juzar; Houman, Justin; Anger, Jennifer T; Eilber, Karyn S


    A known side effect of intravesical onabotulinumtoxinA (Botox®) injection for overactive bladder (OAB) is urinary retention requiring clean intermittent catheterization (CIC), the fear of which deters patients from choosing this therapy. In clinical practice, patients with an elevated postvoid residual (PVR) are often managed by observation only, providing they do not have subjective complaints or contraindications. We sought to determine the true rate of urinary retention requiring CIC in clinical practice. A retrospective review was performed over a 3-year period of patients who received 100 units of intravesical onabotulinumtoxinA for the treatment of OAB. Patients were seen 2 weeks after the procedure to measure PVR. CIC was initiated in patients with a PVR ≥350 ml and in those with subjective voiding difficulty or acute retention. A total of 187 injections were performed on 99 female patients. CIC was required following three injections (1.6%): for acute retention in two patients and subjective voiding difficulty in one patient with a PVR of 353 ml. Following 12 injections, the patient had a PVR of ≥350 ml, and following 29 injections, the patient had a PVR of >200 but <350 ml without symptoms. CIC was not initiated in these 41 patients. None of these patients experienced subsequent retention, and all showed resolution of their elevated PVR within 8 weeks. In our series of 187 intravesical injections for OAB, the rate of postprocedure urinary retention requiring catheterization was only 1.6%. This low rate can be attributed to less rigorous criteria for CIC initiation than those applied in previous studies. While important to counsel patients on the risk of retention, patients can be reassured that the actual rate of CIC is low.

  4. Surgical retrieval of a guide wire lost during central venous catheterization in a dog. (United States)

    Hardy, Jade M; Lansdowne, Jennifer L; Himsel, Carol A; Freer, Sean R


    To report a case of successful surgical removal of a guide wire lost during central venous catheterization. A 28 kg, 4-year-old female neutered mixed breed dog presented to the primary care veterinarian with diabetic ketosis. During the process of central venous catheterization, the guide wire was accidently released and the entire length of the guide wire slipped into the jugular vein. Due to the absence of nearby interventional radiology facilities, surgical intervention was proposed. An ultrasound was used to determine that the guide wire was located in the caudal vena cava extending caudally into the right internal iliac vein. Rommel tourniquets were placed around the iliac vein cranial to the bifurcation of the common iliac vein into the external and internal iliac veins. A venotomy was performed in the right common iliac vein and the guide wire was grasped with hemostats and gently removed while alternately relaxing the cranial then caudal tourniquets. During anesthesia, ventricular premature contractions were noted that varied in frequency with the dog's positioning. Postoperative color flow Doppler ultrasound evaluation of the caudal vena cava, right common, internal and external iliac veins, and right femoral vein was normal with no evidence of thrombosis. Several days postoperative the dog's diabetic ketosis and ventricular premature contractions had resolved and color flow Doppler ultrasound evaluation was normal with no evidence of thrombosis. To the authors' knowledge, this is the first reported veterinary case of loss and subsequent surgical retrieval of a central venous catheter guide wire. © Veterinary Emergency and Critical Care Society 2017.

    Ultrasound guidance for epidural block has improved clinical blind-trial problems but the design of present ultrasonic probes poses operating difficulty of ultrasound-guided catheterization, increasing the failure rate. The purpose of this study was to develop a novel ultrasonic probe to avoid needle contact with vertebral bone during epidural catheterization. The probe has a central circular passage for needle insertion. Two focused annular transducers are deployed around the passage for on-axis guidance. A 17-gauge insulated Tuohy needle containing the self-developed fiber-optic-modified stylet was inserted into the back of the anesthetized pig, in the lumbar region under the guidance of our ultrasonic probe. The inner transducer of the probe detected the shallow echo signals of the peak-peak amplitude of 2.8 V over L3 at the depth of 2.4 cm, and the amplitude was decreased to 0.8 V directly over the L3 to L4 interspace. The outer transducer could detect the echoes from the deeper bone at the depth of 4.5 cm, which did not appear for the inner transducer. The operator tilted the probe slightly in left-right and cranial-caudal directions until the echoes at the depth of 4.5 cm disappeared, and the epidural needle was inserted through the central passage of the probe. The needle was advanced and stopped when the epidural space was identified by optical technique. The needle passed without bone contact. Designs of the hollow probe for needle pass and dual transducers with different focal lengths for detection of shallow and deep vertebrae may benefit operation, bone/nonbone identification, and cost.

    Full Text Available Hamdan Al-HazmiDivision of Urology, Department of Surgery, College of Medicine and King Khalid University Hospital, King Saud University, Riyadh, Saudi ArabiaObjective: Our aim is to prove that duration of catheterization and length of hospital stay (LOS are associated with the rate of hospital-acquired urinary tract infections (UTI, while taking into account type of urinary catheter used, the most common organisms found, patient diagnosis on admission, associated comorbidities, age, sex, precautions that should be taken to avoid UTI, and comparison with other studies.Methods: The study was done in a university teaching hospital with a 920-bed capacity; this hospital is a tertiary care center in Riyadh, Saudi Arabia. The study was done on 250 selected patients during the year 2010 as a retrospective descriptive study. Patients were selected as purposive sample, all of them having been exposed to urinary catheterization; hospital-acquired UTI were found in 100 patients. Data were abstracted from the archived patients' files in the medical record department using the annual infection control logbook prepared by the infection control department. The data collected were demographic information about the patients, clinical condition (diagnosis and the LOS, and possible risk factors for infection such as duration of catheterization, exposure to invasive devices or surgical procedures, and medical condition.Results: There was a statistically significant association between the rate of UTI and duration of catheterization: seven patients had UTI out of 46 catheterized patients (15% at 3 days of catheterization, while 30 patients had UTI out of 44 catheterized patients (68% at 8 days of catheterization (median 8 days in infected patients versus 3 days in noninfected patients; P-value <0.05, which means that the longer the duration of catheterization, the higher the UTI rate. There was a statistically significant association between the rate of UTI and LOS

  8. Determining geographic areas and populations with timely access to cardiac catheterization facilities for acute myocardial infarction care in Alberta, Canada

    Directory of Open Access Journals (Sweden)

    Waters Nigel M


    Full Text Available Abstract Background This study uses geographic information systems (GIS as a tool to evaluate and visualize the general accessibility of areas within the province of Alberta (Canada to cardiac catheterization facilities. Current American and European guidelines suggest performing catheterization within 90 minutes of the first medical contact. For this reason, this study evaluates the populated places that are within a 90 minute transfer time to a city with a catheterization facility. The three modes of transport considered in this study are ground ambulance, rotary wing air ambulance and fixed wing air ambulance. Methods Reference data from the Alberta Chart of Call were interpolated into continuous travel time surfaces. These continuous surfaces allowed for the delineation of isochrones: lines that connect areas of equal time. Using Dissemination Area (DA centroids to represent the adult population, the population numbers were extracted from the isochrones using Statistics Canada census data. Results By extracting the adult population from within isochrones for each emergency transport mode analyzed, it was found that roughly 70% of the adult population of Alberta had access within 90 minutes to catheterization facilities by ground, roughly 66% of the adult population had access by rotary wing air ambulance and that no population had access within 90 minutes using the fixed wing air ambulance. An overall understanding of the nature of air vs. ground emergency travel was also uncovered; zones were revealed where the use of one mode would be faster than the others for reaching a facility. Conclusion Catheter intervention for acute myocardial infarction is a time sensitive procedure. This study revealed that although a relatively small area of the province had access within the 90 minute time constraint, this area represented a large proportion of the population. Within Alberta, fixed wing air ambulance is not an effective means of transporting

  9. Postoperative Complications Leading to Death after Coagulum Pyelolithotomy in a Tetraplegic Patient: Can We Prevent Prolonged Ileus, Recurrent Intestinal Obstruction due to Adhesions Requiring Laparotomies, Chest Infection Warranting Tracheostomy, and Mechanical Ventilation?

    Directory of Open Access Journals (Sweden)

    Subramanian Vaidyanathan


    Full Text Available A 22-year-old male sustained C-6 tetraplegia in 1992. In 1993, intravenous pyelography revealed normal kidneys. Suprapubic cystostomy was performed. He underwent open cystolithotomy in 2004 and 2008. In 2009, computed tomography revealed bilateral renal calculi. Coagulum pyelolithotomy of left kidney was performed. Pleura and peritoneum were opened. Peritoneum could not be closed. Following surgery, he developed pulmonary atelectasis; he required tracheostomy and mechanical ventilation. He did not tolerate nasogastric feeding. CT of abdomen revealed bilateral renal calculi and features of proximal small bowel obstruction. Laparotomy revealed small bowel obstruction due to dense inflammatory adhesions involving multiple small bowel loops which protruded through the defect in sigmoid mesocolon and fixed posteriorly over the area of previous intervention. All adhesions were divided. The wide defect in mesocolon was not closed. In 2010, this patient again developed vomiting and distension of abdomen. Laparotomy revealed multiple adhesions. He developed chest infection and required ventilatory support again. He developed pressure sores and depression. Later abdominal symptoms recurred. This patient’s general condition deteriorated and he expired in 2011. Conclusion. Risk of postoperative complications could have been reduced if minimally invasive surgery had been performed instead of open surgery to remove stones from left kidney. Suprapubic cystostomy predisposed to repeated occurrence of stones in urinary bladder and kidneys. Spinal cord physicians should try to establish intermittent catheterisation regime in tetraplegic patients.

  10. Underrated value of repeated right heart catheterization in pulmonary hypertension with heart failure-a case of persisted pulmonary arterial hypertension after treatment for biventricular failure. (United States)

    Park, Shinhee; Yoon, Hee Young; Jeung, Soomin; Lee, Nah Kyum; Kim, Min-Seok; Ahn, Jung-Min; Kim, Dae-Hee; Lee, Jae Seung


    Pulmonary hypertension (PH) is a common complication of left heart disease and its presence in patients with heart failure predicts worse clinical outcomes. Specific agents targeting pulmonary arterial hypertension (PAH) have been developed over the last few years, but the efficacy of these agents in pulmonary hypertension due to left heart disease (PH-LHD) is uncertain. We report a case of idiopathic pulmonary arterial hypertension (IPAH) initially presented with biventricular failure, which was misdiagnosed as PH-LHD. A 31-year-old man who had a history of recurrent hemoptysis was referred to our center with biventricular failure. Right heart catheterization (RHC) showed elevated mean pulmonary arterial pressure (mPAP) and pulmonary capillary wedge pressure (PCWP). He was diagnosed as having PH-LHD, specifically combined post-capillary and precapillary PH (CpcPH). We treated him for 2 years with diuretics, a beta blocker, an angiotensin-converting enzyme (ACE) inhibitor, and sildenafil, which was added to treat CpcPH. A follow-up echocardiography showed that biventricular function had improved, but not PH. A second RHC revealed elevated mPAP and normal PCWP, which made us change the diagnosis to IPAH. In conclusion, it is important to perform repeated RHC in CpcPH patients after the improvement of left heart dysfunction to distinguish CpcPH from IPAH.

  11. Introducing ultrasound-guided vein catheterization into clinical practice: A step-by-step guide for organizing a hands-on training program with inexpensive handmade models. (United States)

    Di Domenico, S; Licausi, M; Porcile, E; Piaggio, F; Troilo, B; Centanaro, M; Valente, U


    Central vein catheterization (CVC) plays a central role in hospital patient management. Compared with the use of traditional anatomical landmarks, ultrasound-guidance is associated with higher CVC success rates, fewer complications, and more rapid central venous access. The use of US-guided CVC in clinical practice has not become widespread, largely because anesthesiology and general surgery residents receive limited training in this technique. To increase the use of US-guided CVC in our surgical department, we organized a hands-on training program based on the use of handmade models. Three different models were constructed using plastic food-storage containers, segments of rubber tourniquet and silastic tubing (to simulate vessels), and agar gelatin. The hands-on training course allowed progressive acquisition of the basic hand-eye coordination skills necessary for performing US-guided venipuncture. The overall cost for each model was less than €5.00. The models described in this report are useful tools for teaching US-guided CVC. Thanks to their low-cost, they can be widely used to facilitate the introduction of this technique in clinical practice.

    Full Text Available Intravesical Bacillus Calmette-Guerin (BCG instillation is a prophylactic therapy using for treating bladder cancer to prevent tumour progression and recurrence. Both local and systemic complications can arise after the installation. Although local complications are common , this therapy is generally well tolerated. Systemic complications are rarely than local complications but can be fatal. We report a case who died from severe complications such as sepsis, pneumonia, renal failure and granulomatous hepatitis after receiving the first maintanence installation of intravesical BCG immunotherapy for bladder transitional cell carcinoma.

  13. Comparison of role of early (less than six hours) to later (more than six hours) or no cardiac catheterization after resuscitation from out-of-hospital cardiac arrest. (United States)

    Strote, Justin A; Maynard, Charles; Olsufka, Michele; Nichol, Graham; Copass, Michael K; Cobb, Leonard A; Kim, Francis


    Despite reports of patients with resuscitated sudden cardiac arrest (rSCA) receiving acute cardiac catheterization, the efficacy of this strategy is largely unknown. We hypothesized that acute cardiac catheterization of patients with rSCA would improve survival to hospital discharge. A retrospective cohort of 240 patients with out-of-hospital rSCA caused by ventricular tachycardia or fibrillation was identified from 11 institutions in Seattle, Washington from 1999 through 2002. Patients were grouped into those receiving acute catheterization within 6 hours (≤6-hour group, n = 61) and those with deferred catheterization at >6 hours or no catheterization during the index hospitalization (>6-hour group, n = 179). Attention was directed to survival to hospital discharge, neurologic status, extent of coronary artery disease, presenting electrocardiographic findings, and symptoms before arrest. Propensity-score methods were used to adjust for the likelihood of receiving acute catheterization. Survival was greater in patients who underwent acute catheterization (72% in the ≤6-hour group vs 49% in the >6-hour group, p = 0.001). Percutaneous coronary intervention was performed in 38 of 61 patients (62%) in the ≤6-hour group and 13 of 170 patients (7%) in the >6-hour group (p resuscitation. Age, bystander cardiopulmonary resuscitation, daytime presentation, history of percutaneous coronary intervention or stroke, and acute ST-segment elevation were positively associated with receiving cardiac catheterization. In conclusion, in this series of patients who sustained out-of-hospital cardiac arrest, acute catheterization (<6 hours of presentation) was associated with improved survival.

  14. Extended complications of urethroplasty

    Directory of Open Access Journals (Sweden)

    Hosam S. Al-Qudah


    Full Text Available INTRODUCTION: An extensive study of complications following urethroplasty has never been published. We present 60 urethroplasty patients who were specifically questioned to determine every possible early and late complication. MATERIALS AND METHODS: Retrospective chart review of urethroplasty patients between August 2000 and March 2004. An "open format" questioning style allowed maximal patient reporting of all complications, no matter how minor. RESULTS: 60 patients underwent 62 urethroplasties (24 anterior anastomotic, 19 buccal mucosal and 10 fasciocutaneous, 9 posterior anastomotic with mean follow-up of 29 months. Early complications occurred in 40%, but only 3% were major (rectal injury and urosepsis. Early minor complications included scrotal swelling, scrotal ecchymosis and urinary urgency. Late complications occurred in 48%, but only 18% were significant (erectile dysfunction, chordee and fistula. Late minor complications included a feeling of wound tightness, scrotal numbness and urine spraying. Fasciocutaneous urethroplasty caused the most significant complications, and buccal mucus urethroplasty the least, while also resulting in the lowest recurrence rate (0%. CONCLUSIONS: Serious complications after urethroplasty (3% early and 18% late appear similar to those reported elsewhere, but minor bothersome complications appear to occur in much higher numbers than previously published (39% early and 40% late. While all the early complications were resolved and most (97% were minor, less than half of the late complications were resolved, although most (82% were minor. These complication rates should be considered when counseling urethroplasty patients, and generally tend to support the use of buccal mucosal onlay urethroplasty as it had the lowest rate of serious side effects.

  15. An Indwelling Urethral Catheter Knotted Around a Double-J Ureteral Stent: An Unusual Complication after Kidney Transplantation

    Directory of Open Access Journals (Sweden)

    E. G. Warmerdam


    Full Text Available Urethral catheterization is a common procedure with a relatively low complication rate. Knotting of an indwelling urethral catheter is a very rare complication, and there are only a few case reports on knotted catheters, most of them concerning children. We report an especially rare case where a urethral catheter formed a knot around a double-J ureteral stent after a kidney transplantation. We will discuss the various risk factors for knotting of a catheter and the methods to untangle a knot.

  16. Music for anxiety reduction in patients undergoing cardiac catheterization: A systematic review and meta-analysis of randomized controlled trials. (United States)

    Jayakar, Jai P; Alter, David A


    Medical diagnostic procedures, such as cardiac catheterization, can cause significant patient anxiety. Patient anxiety can have negative implications for compliance with healthcare visits, medical tests, and treatments. Music interventions may have a role in reducing anxiety related to cardiac catheterization procedures. To perform a comprehensive systematic review and meta-analysis evaluating whether musical interventions reduce anxiety in patients undergoing cardiac catheterization. MEDLINE, EMBASE, CENTRAL, AMED, and PsychINFO from inception to May 2015. Reference lists of included articles were further hand searched for additional eligible studies. Randomized controlled trials evaluating the effectiveness of music interventions for anxiety reduction in patients undergoing cardiac catheterization. Data on trial design, baseline characteristics and outcomes was extracted using a data extraction table. Study quality and risk of bias were assessed using the JADAD scale. The main outcome was the effectiveness of music interventions in reducing anxiety in this patient population. Meta-analysis was pursued using data from studies that had used the Spielberger state anxiety inventory (STAI-S) to measure anxiety reduction. Other outcomes qualitatively reported include the use of anxiolytic medications and effect on physiological parameters such as blood pressure and heart rate. A total of 15 studies were found to be eligible for inclusion (14 published trials and one conference abstract) in this review. Two-thirds of these studies showed statistically significant reduction in measures of patient anxiety or well-being with musical interventions. Meta-analysis included six studies (n = 695) and showed statistically significant reduction in mean STAI-S scores with music (-3.95 points; 95% confidence -5.53 and -2.37; p value less than 0.005). In conclusion, music is a safe and easily administered intervention that can be used for anxiety reduction among patients

  17. Complications of nephrotic syndrome

    Nephrotic syndrome (NS) is one of the most common glomerular diseases that affect children. Renal histology reveals the presence of minimal change nephrotic syndrome (MCNS) in more than 80% of these patients. Most patients with MCNS have favorable outcomes without complications. However, a few of these children have lesions of focal segmental glomerulosclerosis, suffer from severe and prolonged proteinuria, and are at high risk for complications. Complications of NS are divided into two categories: disease-associated and drug-related complications. Disease-associated complications include infections (e.g., peritonitis, sepsis, cellulitis, and chicken pox), thromboembolism (e.g., venous thromboembolism and pulmonary embolism), hypovolemic crisis (e.g., abdominal pain, tachycardia, and hypotension), cardiovascular problems (e.g., hyperlipidemia), acute renal failure, anemia, and others (e.g., hypothyroidism, hypocalcemia, bone disease, and intussusception). The main pathomechanism of disease-associated complications originates from the large loss of plasma proteins in the urine of nephrotic children. The majority of children with MCNS who respond to treatment with corticosteroids or cytotoxic agents have smaller and milder complications than those with steroid-resistant NS. Corticosteroids, alkylating agents, cyclosporin A, and mycophenolate mofetil have often been used to treat NS, and these drugs have treatment-related complications. Early detection and appropriate treatment of these complications will improve outcomes for patients with NS.

  20. Complications of mechanical ventilation

    Directory of Open Access Journals (Sweden)

    Drašković Biljana


    Full Text Available Mechanical ventilation of the lungs, as an important therapeutic measure, cannot be avoided in critically ill patients. However, when machines take over some of vital functions there is always a risk of complications and accidents. Complications associated with mechanical ventilation can be divided into: 1 airway-associated complications; 2 complications in the response of patients to mechanical ventilation; and 3 complications related to the patient’s response to the device for mechanical ventilation. Complications of artificial airway may be related to intubation and extubation or the endotracheal tube. Complications of mechanical ventilation, which arise because of the patient’s response to mechanical ventilation, may primarily cause significant side effects to the lungs. During the last two decades it was concluded that mechanical ventilation can worsen or cause acute lung injury. Mechanical ventilation may increase the alveolar/capillary permeability by overdistension of the lungs (volutrauma, it can exacerbate lung damage due to the recruitment/derecruitment of collapsed alveoli (atelectrauma and may cause subtle damages due to the activation of inflammatory processes (biotrauma. Complications caused by mechanical ventilation, beside those involving the lungs, can also have significant effects on other organs and organic systems, and can be a significant factor contributing to the increase of morbidity and mortality in critically ill of mechanically ventilated patients. Complications are fortunately rare and do not occur in every patient, but due to their seriousness and severity they require extensive knowledge, experience and responsibility by health-care workers.

  3. Neurologic Complications in Pregnancy. (United States)

    Cuero, Mauricio Ruiz; Varelas, Panayiotis N


    Pregnant women are subject to the same complications as the general population, as well to specific neurologic complications associated with pregnancy, such as preeclampsia or eclampsia. The hormonal and physiologic changes during pregnancy lead to altered incidences of these complications, which usually present during the late period of pregnancy, labor, or the puerperium. In addition, the treatment of these conditions is different from that of nonpregnant women, because special attention is paid to avoid any abnormalities or death of the fetus. This article discusses the most common of these neurologic complications. Copyright © 2016 Elsevier Inc. All rights reserved.

  4. The postanesthetic period. Complications. (United States)

    Malamed, S F


    Postanesthetic complications can occur even in the best of circumstances. Proper preparation of the staff, aggressive monitoring of the recovering patient, and early recognition and management of the complications are essential if the outcome is to be successful. In reviewing postanesthetic complications, two factors are present in the overwhelming majority of situations--hypoxia and hypercarbia--often the direct result of inadequate monitoring during the postanesthetic period. The anesthetic procedure is not over once the anesthetic agents are discontinued. The skillful anesthetist is aware of the possibilities of postoperative complications and prevents problems by employing enhanced monitoring techniques during the recovery phase.

  5. A rare instructive complication of balloon catheter fracture during percutaneous coronary intervention. (United States)

    Nomura, Tetsuya; Higuchi, Yusuke; Kato, Taku; Keira, Natsuya; Tatsumi, Tetsuya


    The entrapment, fracture, and dislodgement of catheterization devices during percutaneous coronary intervention (PCI) are rare complications, for which cardiac surgery is sometimes required. Here, we encountered a rare but instructive case of balloon catheter fracture during PCI. Although there have been some reports of guidewire fracture in PCI, reports on balloon catheter fracture are very rare to our knowledge. A simulation test to examine the mechanism of balloon catheter fracture revealed that overuse of the balloon catheter, both for kissing balloon inflation and balloon anchor, was highly likely to have been the cause of the fracture.

  6. Randomized controlled trial on the impact of music therapy during cardiac catheterization on reactive hyperemia index and patient satisfaction: the Functional Change in Endothelium After Cardiac Catheterization, With and Without Music Therapy (FEAT) study. (United States)

    To determine the impact of music intervention on endothelial function, hemodynamics, and patient anxiety before, during, and after cardiac catheterization. The effect of music therapy during cardiac catheterization on endothelial function and patient satisfaction has received limited study. Seventy patients undergoing elective cardiac catheterization were randomized to music therapy (n=36) or no music therapy (n=34). Peripheral arterial tonometry was performed before and after catheterization. A 6 item (24-point scale) questionnaire evaluating patient anxiety and discomfort levels was also administered after the procedure. Both study groups had similar baseline characteristics, fluoroscopy time, and contrast administration. Reactive hyperemia index (RHI) change was 0.14 ± 0.72 in the music group and 0.30 ± 0.58 in the control group (P=.35). Systolic and diastolic blood pressure (BP) changes did not significantly differ between the two groups (systolic BP change -3.3 ± 17.3 mm Hg vs -2.3 ± 19.4 mm Hg; P=.83 and diastolic BP change -1.9 ± 12.2 mm Hg vs. 2.0 ± 13.4 mm Hg; P=.23). Heart rate changes were also comparable between the two groups (-1 ± 6 beats/ min vs -1 ± 7 beats/min; P=.22). Patient satisfaction questionnaire measurements were found to be similar in patients with and without music therapy (8 [7-11] vs 9 [8-12]; P=.36). In this study, music intervention did not elicit a vasodilator response, did not lower blood pressure or heart rate, and did not relieve anxiety or stress discomfort in patients who underwent coronary angiography.

  7. Complications Involving Central Venous Catheter Insertion in Newborns Admitted to the Neonatal Intensive Care Unit (NICU

    Directory of Open Access Journals (Sweden)



    Full Text Available Background Developments in the use of central venous catheters have improved the treatment of critically ill newborns. Objectives The aim of this retrospective study was to evaluate the rate of catheter-related complications and associated risk factors in newborns. Patients and Methods This cross sectional study evaluated 60 infants with indications for central venous catheters who were selected by census from 2007 to 2014 in Baqiyatallah Hospital in Tehran, Iran. The catheters were Broviac numbers 14 - 16. Results Ultimately, 60 cases (17 males and 43 females with a mean age of 26.25 ± 20.09 days (Min = 1 day and Max = 153 days underwent analysis. The most common reasons for venous catheter placement (98.3% were prolonged hospitalization and lack of peripheral vessels. The most common complication was catheter-related infection, which occurred in 20 patients (33.3%. Death occurred in 24 patients (40.0%, but only 3 deaths (5% were due to complications from the central venous catheter. A significant relationship was evident between infection and catheterization duration (P = 0.02. Conclusions Most of the catheter-related deaths were due to severe sepsis and hemothorax, and a significant relationship was noted between infection and both the mortality rate and catheterization duration. A significant relationship was also evident between birth weight and infection rates.

    We present an initial evaluation of a robotic arm for positioning a 3D echo probe during cardiac catheterization procedures. By tracking the robotic arm, X-ray table and X-ray C-arm, we are able to register the 3D echo images with live 2D X-ray images. In addition, we can also use tracking data from the robotic arm combined with system calibrations to create extended field of view 3D echo images. Both these features can be used for roadmapping to guide cardiac catheterization procedures. We have carried out a validation experiment of our registration method using a cross-wire phantom. Results show our method to be accurate to 3.5 mm. We have successfully demonstrated the creation of the extended field of view data on 2 healthy volunteers and the registration of echo and X-ray data on 1 patient undergoing a pacing study.

  10. Central Venous Access in the Pediatric Population With Emphasis on Complications and Prevention Strategies. (United States)

    Duesing, Lori A; Fawley, Jason A; Wagner, Amy J


    Central venous catheters are often necessary in the pediatric population. Access may be challenging, and each vessel presents its own unique set of risks and complications. Central venous catheterization is useful for hemodynamic monitoring, rapid fluid infusion, and administration of hyperosmolar medications, including vasopressors, antibiotics, chemotherapy, and parenteral nutrition. Recent advances have improved the catheters used as well as techniques for insertion. A serious complication of central access is infection, which is associated with morbidity, mortality, and significant financial costs. Reduction of catheter-related bloodstream infections is realized with use of ethanol locks, single lumens when appropriate, and prudent adherence to insertion and maintenance bundles. Ultrasound guidance used for central venous catheter placement improves accuracy of placement, reducing time and unsuccessful insertion and complication rates. Patients with central venous catheters are best served by multidisciplinary team involvement. © 2016 American Society for Parenteral and Enteral Nutrition.

  15. Lidocaine Gel for Urethral Catheterization in Children: A Meta-Analysis. (United States)

    Chua, Michael E; Firaza, Paul Nimrod B; Ming, Jessica M; Silangcruz, Jan Michael A; Braga, Luis H; Lorenzo, Armando J


    To compare the efficacy and safety of lidocaine gel vs nonanesthetic gel (NAG) in reducing transurethral bladder catheterization (TUBC) procedural pain in children. A systematic literature search was done using electronic medical databases and trial registries up to September 2016 with no language restrictions. Randomized controlled trials (RCTs) that assessed the efficacy and safety of lidocaine gel vs NAG in reducing TUBC-associated pain in children were screened, identified, and appraised. Risks of bias and study quality of the eligible trials were assessed according to the Cochrane Collaboration recommendations. Various pain assessment scales from the included studies were extracted as mean differences and standard deviations for each treatment group. Standardized mean differences (SMDs) were generated with 95% CIs for between-group difference estimation. Effect estimates were pooled using the inverse variance method with a random-effects model. Subgroup analysis was performed for different age groups. Five RCTs (with a total of 369 children) were included. Overall pooled effect estimates showed that compared with NAG, lidocaine gel has no significant benefit in decreasing TUBC-associated pain in children (SMD, -0.22; 95% CI, -0.65 to 0.21). Effect estimates from 4 studies revealed no difference in pain reduction between the lidocaine gel and NAG in children aged lidocaine gel use were reported in any of the studies. Lidocaine gel does not appear to reduce TUBC pain compared with NAG, specifically in children aged <4 years. CRD42016050018. Copyright © 2017 Elsevier Inc. All rights reserved.

  16. Brightness of venous blood in South American camelids: implications for jugular catheterization. (United States)

    Grint, Nicola; Dugdale, Alexandra


    To compare the brightness of South American camelid venous blood to that of Equidae. Prospective clinical evaluation. Twelve South American camelids (eight llamas, four alpacas), eight horses and ponies (control group). Appropriately sized catheters were placed in the jugular vein of each animal under local anaesthesia. The blood spilt before the catheter was capped was caught on a white tile. A sample of blood was drawn for blood-gas analysis. The brightness of the blood (both on the tile and in the syringe) was matched to a colour chart (1 = darkest red, 8 = brightest red) by a single observer under bright light conditions. Packed cell volume (PCV) and partial pressure of oxygen (PvO(2)) in the blood were also measured on the syringe blood. Normally distributed data were compared using a two tailed t-test, and non-normally distributed data were compared using a Mann-Whitney U-test. Significance was set at p < 0.05. Camelid venous blood was significantly brighter red than that of horses and ponies both on the white tile (p = 0.0003) and in the syringe (p = 0.0001). PCV was significantly lower in camelids (32 +/- 4%) compared with horses (37 +/- 5%). Partial pressure of oxygen values were similar between groups. Jugular venous blood in alpacas and llamas is significantly brighter red than that of horses. Colour should not be used as a sole determinant of venous or arterial catheterization in this species.

  17. Teaching children clean intermittent self-catheterization (CISC) in a group setting. (United States)

    Cobussen-Boekhorst, Hanny J G L; Kuppenveld Van, Jet H P A; Verheij, Perijn P J P W; Jong De, Lieke L W M; Gier De, Robert R P E; Kortmann, Barbara B B M; Feitz, Wouter W F J


    To teach children to perform clean intermittent self-catheterization (CISC) at our institution, the nurse practitioner uses a step-by-step approach in combination with an instruction model in an outpatient setting. For a small group of children the procedure remains difficult to learn. For them, we developed a multidisciplinary, group-wise training program. Small groups of children, aged 7-12 years, and their parents consulted our clinic during six meetings. The group training was provided by a pediatric urology nurse practitioner, physiotherapist and behavioural practitioner. Using a tell/show/do method each intervention was instructed group wise. The actual CISC was performed individually within a private setting. Elements of the training were: sharing of mastery and difficulties with other children/parents, cognitive restructuring to enhance understanding and motivation, handling and trying out of devices, relaxation as a response to physical stress, and supporting parental guidance. The preliminary results of seven children were successful after group-wise intervention. Children were less anxious and more cooperative. Parents could share their difficulties dealing with their child at home and were given suggestions to help their children with CISC. Group interactions and a multidisciplinary approach seems to be of great help in learning CISC for selected children. Copyright (c) 2010 Journal of Pediatric Urology Company.

  18. Novel miniature mobile cardiac catheterization laboratory for critical cardiovascular disease following natural disasters: a feasibility study. (United States)

    Han, Ya-ling; Liang, Zhuo; Yao, Tian-ming; Sun, Jing-yang; Liang, Ming; Huo, Yu; Wang, Geng; Wang, Xiao-zeng; Liang, Yan-chun; Meng, Wei-hong


    Natural disasters have been frequent in recent years. Effective treatment of patients with cardiovascular disease following natural disasters is an unsolved problem. We aimed to develop a novel miniature mobile cardiac catheterization laboratory (Mini Mobile Cath Lab) to provide emergency interventional services for patients with critical cardiovascular disease following natural disasters. A feasibility study was performed by testing the Mini Mobile Cath Lab on dogs with ST-elevation myocardial infarction (STEMI) model in a hypothetical natural-disaster-stricken area. The Mini Mobile Cath Lab was transported to the hypothetical natural-disaster-stricken area by truck. Coronary angiography and primary percutaneous coronary intervention (PCI) were performed on six dogs with STEMI model. The transportation and transformation of the Mini Mobile Cath Lab were monitored and its functioning was evaluated through the results of animal experiments. The Mini Mobile Cath Lab could be transported by truck at an average speed of 80 km/h on mountain roads during daytime in the winter, under conditions of light snow (-15°C to -20°C/-68°F to -59°F). The average time required to prepare the Mini Mobile Cath Lab after transportation, in a wetland area, was 30 minutes. Coronary angiography, and primary PCI were performed successfully. This preliminary feasibility study of the use of the Mini Mobile Cath Lab for emergency interventional treatment of dogs with STEMI indicated that it may perform well in the rescue of critical cardiovascular disease following natural disasters.

  19. Microcomputer-assisted filing system of cardiac catheterization records using a relational database management system. (United States)

    Mohri, M; Kikuchi, Y; Sagara, T; Sugihara, M


    To efficiently store and retrieve cardiac catheterization records, we have developed a computer-assisted database, which comprises a 16-bit microcomputer with dual floppy disk drives, a 20 MB random-access memory, hard disk drive, and a line printer. All programmings were accomplished using a relational database management system (R:base 5000, Microrim, Inc.). Data inquiry procedures could be performed with direct operational commands of the system as well as with preprogrammed command files, and final results of searches were printed out with a line printer. The major advantages of the present system described in this report include: (1) the relatively easy and rapid creation of the database, (2) ease of modification of the database structures even after the system design is finished, (3) operational commands in combination with conditional operator(s) are flexible and powerful enough to allow the end user to retrieve data based on various kinds of criteria, (4) a high-level programming language provided by the R:base automates a series of database procedures with relative ease, (5) relational capabilities of the database management system can enhance the possibility of reconstruction of a new data file from a single or several preexisting data files, and (6) the system can be realized at reasonable cost.

  20. Association between clean intermittent catheterization and urinary tract infection in infants and toddlers with spina bifida. (United States)

    Kaye, I Y; Payan, M; Vemulakonda, V M


    The primary goal of urologic management in children with spina bifida is to reduce the risk of urinary tract infection (UTI) and associated renal injury. While clean intermittent catheterization (CIC) has been the mainstay of treatment, recent studies have suggested that this approach is not without risk. The objective of this study was to examine the association between alternative bladder management strategies and UTI in infants and toddlers with spina bifida. A retrospective cohort study was conducted on spina bifida patients, aged 0-3 years, seen in a multidisciplinary spinal defects clinic between 2008 and 2013. Inclusion criteria included: a primary diagnosis of meningocele, myelomeningocele, or lipomyelomeningocele. Patients were excluded if they had: spina bifida who were initially managed with spontaneous voiding had a lower risk of UTI than those managed with CIC. Patients who switched to CIC after a period of initial observation with voiding did not have a significantly different risk of UTI compared with those managed with CIC alone. These findings suggest that early initiation of CIC may not be warranted in all infants with spina bifida. Further studies are needed to more clearly define optimal indications for initiation of CIC in these patients. Copyright © 2016 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

  1. Case Report of First Angiography-Based On-Line FFR Assessment during Coronary Catheterization

    Directory of Open Access Journals (Sweden)

    Ran Kornowski


    Full Text Available Fractional flow reserve (FFR, an index of the hemodynamic severity of coronary stenoses, is derived from hyperemic pressure measurements and requires a pressure-monitoring guide wire and hyperemic stimulus. Although it has become the standard of reference for decision-making regarding coronary revascularization, the procedure remains underutilized due to its invasive nature. FFRangio is a novel technology that uses the patient’s hemodynamic data and routine angiograms to generate a complete three-dimensional coronary tree, with color-coded display of the FFR values at each point along the vessels. After being proven to be as accurate as invasive FFR measurements in an off-line study, this case report presents the first on-line application of the system in the catheterization lab. Here too, a high concordance between FFRangio and invasive FFR was observed. In light of the demonstrated capabilities of the FFRangio system, it should emerge as an important tool for clinical decision-making regarding revascularization in patients with coronary artery disease.

  3. ARFI ultrasound for in vivo hemostasis assessment postcardiac catheterization, part II: pilot clinical results. (United States)

    Behler, Russell H; Scola, Mallory R; Nichols, Timothy C; Caughey, Melissa C; Fisher, Melrose W; Zhu, Hongtu; Gallippi, Caterina M


    In this second of a two part series, we present pilot clinical data demonstrating Acoustic Radiation Force Impulse (ARFI) ultrasound for monitoring the onset of subcutaneous hemostasis at femoral artery puncture sites (arteriotomies), in vivo. We conducted a randomized, reader-blinded investigation of 20 patient volunteers who underwent diagnostic percutaneous coronary catheterization. After sheath removal (6 French), patients were randomized to treatment with either standard of care manual compression alone or, to expedite hemostasis, manual compression augmented with a p-GlcNAc fiber-based hemostatic dressing (Marine Polymer Technologies, Danvers MA). Concurrent with manual compression, serial ARFI imaging began at the time of sheath removal and continued every minute for 15 min. Serial data sets were processed with custom software to (1) estimate the time of hemostasis onset, and (2) render hybrid ARFI/B-Mode images to highlight displacements considered to correspond to extravasted blood. Images were read by an observer blinded to the treatment groups. Average estimated times to hemostasis in patient volunteers treated with manual compression alone (n = 10) and manual compression augmented by hemostatic dressing (n = 9) were, respectively, 13.00 +/- 1.56 and 9.44 +/- 3.09 min, which are statistically significantly different (p = 0.0065, Wilcoxon two-sample test). Example images are shown for three selected patient volunteers. These pilot data suggest that ARFI ultrasound is relevant to monitoring subcutaneous bleeding from femoral arteriotomies clinically and that time to hemostasis was significantly reduced by use of the hemostatic dressing.

  4. Bulimia Nervosa - medical complications. (United States)

    Mehler, Philip S; Rylander, Melanie


    As with anorexia nervosa, there are many medical complications associated with bulimia nervosa. In bulimia nervosa, these complications are a direct result of both the mode and the frequency of purging behaviours. For the purposes of this article, we will review in detail the many complications of the two major modes of purging, namely, self-induced vomiting and laxative abuse; these two account for more than 90% of purging behaviours in bulimia nervosa. Some of these complications are potentially extremely dangerous and need to be well understood to effectively treat patients with bulimia nervosa. Other methods of purging, such as diuretic abuse, are much less frequently utilized and will only be mentioned briefly. In a subsequent article, the treatments of these medical complications will be presented.

    Full Text Available Background and Objectives: Given the increasing prevalence of use of urinary catheter, nurses as one of the largest and the most important health care provider groups, should have extensive knowledge and skills in order to provide standard health care. This study was conducted to determine the conformity rate of the principles of catheterization nursing care in women with the standards in selected Hospital of Qom University of Medical Sciences, 2015. Methods: In this descriptive cross-sectional study, 195 cases of catheterization nursing care in women, were investigated using event sampling in one of the hospitals affiliated to Qom University of Medical Sciences, in 2015. Data were gathered through Nurses' Demographic Information Questionnaire and checklist of catheterization nursing care in women. Results: In this study, the conformity rate of catheterization nursing care with the standards was 70.8% (moderate; 29.2% of the care was desirable; and 0% was poor. Conclusion: According to the results, nurses’ performance in the catheterization nursing care in women was in moderate level compared to the standards. In order to improve the quality of cares, implementation of nursing clinical guidelines for women catheterization, and clinical supervision by nurse managers, are suggested.

    Echocardiography is the first-line modality for the investigation of neonatal congenital heart disease. Diagnostic cardiac catheterization, which has a small but recognized risk, is usually performed if echocardiography fails to provide a confident evaluation of the lesions. To verify the technical and clinical feasibilities of replacing diagnostic cardiac catheterization with multidetector-row CT (MDCT) in neonatal complex congenital heart disease. Over a 1-year period we prospectively enrolled all neonates with complex congenital heart disease referred for diagnostic cardiac catheterization after initial assessment by echocardiography. MDCT was performed using a 40-detector-row CT scanner with dual syringe injection. A multidisciplinary congenital heart disease team evaluated the MDCT images and decided if further diagnostic cardiac catheterization was necessary. The accuracy of MDCT in detecting separate cardiovascular anomalies and bolus geometry of contrast enhancement were calculated. A total of 14 neonates were included in the study. No further diagnostic cardiac catheterization was needed in any neonate. The accuracy of MDCT in diagnosing separate cardiovascular anomalies was 98% (53/54) with only one atrial septal defect missed in a patient with coarctation syndrome. The average cardiovascular enhancement in evaluated chambers was 471 HU. No obvious beam-hardening artefact was observed. The technical and clinical feasibility of MDCT in complex congenital heart disease in neonates is confirmed. After initial assessment with echocardiography, MDCT could probably replace diagnostic cardiac catheterization for further anatomical clarification in neonates. (orig.)

  7. Urological complications of coitus. (United States)

    Eke, N


    To ascertain the urological complications of coitus, as the proximity of the lower urinary tract to the organs of coitus exposes the tract to coital trauma. Medline was searched from 1966 to 2000 to identify reports on coital injuries. Publications and relevant references were retrieved. Those reporting urological complications were selected for analysis. In all, 1454 cases of reported coital injuries were reviewed; 790 occurred in men while 664 occurred in women, mainly in the genital area. Physical urological complications were more common in men than in women. The injuries were often sustained during voluntary coitus, but one penile fracture was sustained during an attempted rape. The presentations included penile swellings and deviations, haemorrhage, erectile dysfunction and urinary incontinence. Complications included vesicovaginal fistulae, bladder and cavernosal ruptures, and urinary tract infections. Rare complications included isolated rupture of the penile vasculature. Major risk factors included penovaginal disproportion, excessive force at coitus, urethral coitus, fellatio and anal intercourse. Urethral injuries were the commonest complications; in men these were associated with 10-38% of penile fractures. The treatments included cold compress and anti-inflammatory agents in contusions, repairs of lacerations, closure of fistulae and urethral and vaginal reconstruction. The results of treatment were essentially good. Recurrent penile fractures were reported. Coitus, although pleasurable, may be risky. The complications have been termed 'faux pas' implying that they are preventable. While the ultimate prevention is abstinence, this is an unrealistic prescription. Therefore, efforts are necessary to identify risk factors to enable preventive strategies.

  8. Clean intermittent catheterization as an initial management strategy provides for adequate preservation of renal function in newborns with persistent cloaca. (United States)

    Chalmers, David J; Rove, Kyle O; Wiedel, Cole A; Tong, Suhong; Siparsky, Georgette L; Wilcox, Duncan T


    Persistent cloaca is a rare, congenital anomaly involving the genital, urinary, and rectal organ systems. While prompt bowel diversion is the standard of care, the optimal method of genitourinary decompression is unclear. Bladder outlet obstruction and hydrometrocolpos are common complications that can lead to obstructive uropathy, abdominal distention, infection, perforation, and acidosis. Proposed management strategies include early surgical diversion (vesicostomy, vaginostomy, ureterostomy, nephrostomy) or clean intermittent catheterization (CIC) of the common channel. We hypothesized that CIC is an adequate means of genitourinary decompression and preservation of renal function, regardless of the severity of cloacal anomaly. We reviewed all patients with persistent cloaca from a single, tertiary care center from 1995 to 2013. We collected data regarding renal function (serial serum creatinine prior to definitive reconstruction, and baseline estimated glomerular filtration rate [GFR]), presence of hydrocolpos, hydronephrosis, vesicoureteral reflux (VUR) or renal dysplasia, and length of the common channel. A linear mixed model was used to calculate creatinine change over time in relation to method of management and child age. Estimated GFR was calculated using the Schwartz equation for neonates = 0.45 × height in cm/serum creatinine in mg/dL. The t test was used for continuous data and Fisher's exact test was used for binomial data. A p value five patients were identified. Nine (36%) patients underwent early surgical diversion versus 16 (64%) managed by CIC prior to formal reconstruction. Seven had short common channels (management groups, there was no significant difference in hydronephrosis, high-grade hydronephrosis (grades III-IV, p = 0.62), any VUR (p = 0.33), high-grade VUR (grades III-V, p = 0.62), hydrocolpos (p = 0.21), or renal dysplasia (p = 0.42). No significant differences were found between mean baseline GFR for diversion (22.9 mL/min per 1.73 m(2

  9. Complications Following Pediatric Tracheotomy. (United States)

    D'Souza, Jill N; Levi, Jessica R; Park, David; Shah, Udayan K


    Pediatric tracheotomy is a complex procedure with significant postoperative complications. Wound-related complications are increasingly reported and can have considerable impact on clinical course and health care costs to tracheotomy-dependent children. The primary objective of this study was to identify the type and rate of complications arising from pediatric tracheotomy. A retrospective review of medical records of 302 children who underwent tracheotomy between December 1, 2000, and February 28, 2014, at a tertiary care pediatric referral center. Records were reviewed for preoperative diagnoses, gestational age, age at tracheotomy, tracheotomy technique, and incidence of complication. Main outcome measures included incidence, type, and timing of complications. Secondary measures included medical diagnoses and surgical technique. Of the 302 children who underwent tracheotomy, the median (SD) age at time of tracheotomy was 5 months (64 months) and the range was birth to 21 years. The most frequent diagnosis associated with performance of a tracheotomy was ventilator-associated respiratory failure (61.9%), followed by airway anomaly or underdevelopment (25.2%), such as subglottic or tracheal stenosis, laryngotracheomalacia, or bronchopulmonary dysplasia. The remaining indications for tracheotomy included airway obstruction (11.6% [35 of 302]) and vocal fold dysfunction (1.3% [4 of 302]). No statistical significance was found associated with diagnosis and incidence of complications. Sixty children (19.9%) had a tracheotomy-related complication. Major complications, such as accidental decannulation (1.0% [3 of 302]). There were no deaths associated with tracheotomy. Minor complications, such as peristomal wound breakdown or granuloma (12.9% [39 of 302]) and bleeding from stoma (1.7% [5 of 302]), were more common. Of all complications, 70% (42 of 60) occurred early (≤7 days postoperatively) and 20% (12 of 60) were late (>7 days postoperatively). Pediatric

  13. [Complications of cocaine addiction]. (United States)

    Karila, Laurent; Lowenstein, William; Coscas, Sarah; Benyamina, Amine; Reynaud, Michel


    Addiction is a chronic relapsing disorder characterized by repetitive and compulsive drug-seeking behavior and drug abuse despite negative health or social consequences. Cocaine addiction is a significant worldwide public health problem, which has somatic, psychological, psychiatric, socio-economic and judicial complications. Some of the most frequent complications are cardiovascular effects (acute coronary syndrome, cardiac arrhythmias, increased blood pressure); respiratory effects (fibrosis, interstitial pneumonitis, pulmonary hypertension, alveolar haemorrhage, asthma exacerbation; emphysema), neurological effects (strokes, aneurysms, seizures, headaches); risk for contracting HIV/AIDS, hepatitis B and C, sexual transmitted disease and otolaryngologic effects. Other complications are not discussed here. The vast majority of studies indicate that there are cognitive deficits induced by cocaine addiction. Attention, visual and working memories, executive functioning are affected in cocaine users. Psychiatric complications found in clinical practice are major depressive disorders, cocaine-induced paranoia, cocaine-induced compulsive foraging and panic attacks.

  15. Complications of Circumcision

    Directory of Open Access Journals (Sweden)

    Aaron J. Krill


    Full Text Available In the United States, circumcision is a commonly performed procedure. It is a relatively safe procedure with a low overall complication rate. Most complications are minor and can be managed easily. Though uncommon, complications of circumcision do represent a significant percentage of cases seen by pediatric urologists. Often they require surgical correction that results in a significant cost to the health care system. Severe complications are quite rare, but death has been reported as a result in some cases. A thorough and complete preoperative evaluation, focusing on bleeding history and birth history, is imperative. Proper selection of patients based on age and anatomic considerations as well as proper sterile surgical technique are critical to prevent future circumcision-related adverse events.

    Fenster, Howard N.; Scarrow, Gayle D.


    Unlike the general public, quadriplegics are prone to various urological complications as a direct/indirect result of spinal cord lesions. These complications include neurogenic bladder, urinary tract infections, renal and bladder calculi, obstructive uropathy, renal failure, and bladder neoplasms. A significant portion of upper urinary tract disease, including pyelonephritis, hypernephrosis, and calculi are usually secondary to neurogenic bladder related to detrusor sphincter dysfunction.

  1. Neurologic complications of vaccinations. (United States)

    Miravalle, Augusto A; Schreiner, Teri


    This chapter reviews the most common neurologic disorders associated with common vaccines, evaluates the data linking the disorder with the vaccine, and discusses the potential mechanism of disease. A literature search was conducted in PubMed using a combination of the following terms: vaccines, vaccination, immunization, and neurologic complications. Data were also gathered from publications of the American Academy of Pediatrics Committee on Infectious Diseases, the World Health Organization, the US Centers for Disease Control and Prevention, and the Vaccine Adverse Event Reporting System. Neurologic complications of vaccination are rare. Many associations have been asserted without objective data to support a causal relationship. Rarely, patients with a neurologic complication will have a poor outcome. However, most patients recover fully from the neurologic complication. Vaccinations have altered the landscape of infectious disease. However, perception of risk associated with vaccinations has limited the success of disease eradication measures. Neurologic complications can be severe, and can provoke fear in potential vaccines. Evaluating whether there is causal link between neurologic disorders and vaccinations, not just temporal association, is critical to addressing public misperception of risk of vaccination. Among the vaccines available today, the cost-benefit analysis of vaccinations and complications strongly argues in favor of vaccination. © 2014 Elsevier B.V. All rights reserved.

  2. On complicity theory. (United States)

    Kline, A David


    The received account of whistleblowing, developed over the last quarter century, is identified with the work of Norman Bowie and Richard DeGeorge. Michael Davis has detailed three anomalies for the received view: the paradoxes of burden, missing harm and failure. In addition, he has proposed an alternative account of whistleblowing, viz., the Complicity Theory. This paper examines the Complicity Theory. The supposed anomalies rest on misunderstandings of the received view or misreadings of model cases of whistleblowing, for example, the Challenger disaster and the Ford Pinto. Nevertheless, the Complicity Theory is important for as in science the contrast with alternative competing accounts often helps us better understand the received view. Several aspects of the received view are reviewed and strengthened through comparison with Complicity Theory, including why whistleblowing needs moral justification. Complicity Theory is also critiqued. The fundamental failure of Complicity Theory is its failure to explain why government and the public encourage and protect whistleblowers despite the possibility of considerable harm to the relevant company in reputation, lost jobs, and lost shareholder value.

  3. YouTube as an educational tool regarding male urethral catheterization. (United States)

    Nason, Gregory J; Kelly, Padraig; Kelly, Michael E; Burke, Matthew J; Aslam, Asadullah; Giri, Subhasis K; Flood, Hugh D


    Urethral catheterization (UC) is a common procedure carried out on a daily basis. The aims of this study were to assess the quality of YouTube as an educational tool regarding male UC and to assess the experience of newly qualified doctors regarding UC. YouTube was searched for videos containing relevant information about male UC. A checklist for evaluating content for male UC was devised. The top-ranked video was shown to interns and they were questioned regarding their experience of UC and the usefulness of the video. A total of 100 videos was screened and 49 unique videos were identified. The median length of video was 7 min 15 s (range 1 min 44 s to 26 min 44 s). Regarding the Safe Catheter Insertion Score, the mean score was 5.18 ± 1.64. 9 (18.4%) deemed useful, 24 (49%) somewhat useful and 16 (32.7%) not useful. There was no difference in the number of views (p = 0.487), duration of video (p = 0.364) or number of days online (p = 0.123) between those categorized as useful, somewhat useful and not useful. Twenty-six interns (89.7%) attended the UC teaching session. All reported the video to be a useful educational adjunct. Nine of the respondents (42.9%) had independently inserted a urinary catheter before the educational session. The quality of videos on YouTube regarding male UC is widely variable. Preselected videos are deemed useful by junior doctors regarding male UC and can be used as an educational adjunct before performing hands-on tasks.

  4. Cardiac catheterization: impact of face and neck shielding on new estimates of effective dose. (United States)

    von Boetticher, Heiner; Lachmund, Jörn; Hoffmann, Wolfgang


    Optimization of radiation protection devices for the operator is achieved by minimizing the effective dose (E) on the basis of the recommendations of Publications 60 and 103 of the International Commission on Radiological Protection (ICRP). Radiation exposure dosimetry was performed with thermoluminescence dosimeters using one Alderson phantom in the patient position and a second one in the typical position of the operator. Various types of protective clothing as well as fixed leaded shieldings (table mounted shielding and overhead suspended shields) were considered calculating E. Shielding factors for protective equipment can readily be misinterpreted referring to the reduction of the effective dose because fixed protective barriers as well as radiation protection clothing are shielding only parts of the body. With the ICRP 103 approach relative to the exposure without lead protection, a lead apron of 0.35 or 0.5 mm thickness reduces E to 14.4 or 12.3%, respectively; by using an additional thyroid collar, these values are reduced to 9.7 or 7.5%. A thyroid collar reduces the effective dose by more than an increase of the lead equivalency of the existing apron. Wearing an apron of 0.5 mm lead-equivalent with a thyroid collar and using an additional side shield, E decreases to 6.8%. Using both a fixed side and face shield decreases E to 2.0%. For protective garments including thyroid protection, the values of the effective dose in cardiac catheterization are 47-106% higher with ICRP 103 than with ICRP 60 recommendations. This is essentially caused by the introduction of new factors for organs in the head and neck region in ICRP 103.

    Hilário, Thamires de Souza; Santos, Simone Marques Dos; Kruger, Juliana; Goes, Martha Georgina; Casco, Márcia Flores; Rabelo-Silva, Eneida Rejane


    To describe how pain is assessed (characteristic, location, and intensity) and managed in clinical practice in patients undergoing endovascular procedures in the catheterization laboratory setting. Cross-sectional study with retrospective data collection. Overall, 345 patients were included; 116 (34%) experienced post-procedural pain; in 107 (92%), pain characteristics were not recorded; the location of pain was reported in 100% of patients, and its intensity in 111 (96%); management was largely pharmacologic; of the patients who received some type of management (n=71), 42 (59%) underwent reassessment of pain. The location and intensity of pain are well reported in clinical practice. Pharmacologic pain management is still prevalent. Additional efforts are needed to ensure recording of the characteristics of pain and its reassessment after interventions. Describir cómo se evalúa el dolor (características, localización e intensidad) y su manejo en la práctica clínica en pacientes sometidos a procedimientos endovasculares en el laboratorio de cateterización. Estudio transversal con recolección retrospectiva de datos. En total, se incluyeron 345 pacientes; 116 (34%) experimentaron dolor post-procedimiento; en 107 (92%), no se registraron las características del dolor; la localización del dolor se informó en el 100% de los pacientes, y su intensidad en 111 (96%); el manejo fue en gran medida farmacológico; de los pacientes que recibieron algún tipo de tratamiento (n=71), 42 (59%) fueron sometidos a reevaluación del dolor. La ubicación y la intensidad del dolor se informan bien en la práctica clínica. El manejo farmacológico del dolor sigue siendo frecuente. Se necesitan esfuerzos adicionales para asegurar el registro de las características del dolor y su reevaluación después de las intervenciones.

  6. Sperm evaluation and biochemical characterization of cat seminal plasma collected by electroejaculation and urethral catheterization. (United States)

    Zambelli, Daniele; Raccagni, Ramona; Cunto, Marco; Andreani, Giulia; Isani, Gloria


    This paper aimed to evaluate cat seminal plasma protein profile (with SDS-page) and determine differences in seminal plasma composition from ejaculates obtained using urethral catheterization after pharmacological induction (UrCaPI) and electroejaculation (EE). In addition, this study evaluates whether the recovery method affected seminal plasma protein and zinc concentrations. A single ejaculation was collected from 17 mixed-breed cats by EE (5/21) or UrCaPI (12/21), while 4/21 cats underwent four sperm collections once every four days using EE and UrCaPI techniques alternately. The semen parameters evaluated were: volume, percentage of motility and progressive motility, morphology, and sperm concentration. After centrifugation, the seminal plasma obtained was stored at -80 °C and later used to measure protein and zinc concentrations, and to determine protein profile by SDS-polyacrylamide gel electrophoresis (PAGE). The results obtained indicate that cat seminal plasma protein profile is characterized by many protein bands (>30) with a molecular weight ranging from 3.5 to 200 kDa, and that the recovery method influences the seminal plasma protein profile: EE is related to the absence of two proteins (P55 and P14), and alters three protein bands (P200, P80, P28). The collection technique also affected zinc concentration (mg/dL) and protein concentration (g/dL) which were significantly higher (P < 0.01) in samples collected by UrCaPI; on the contrary the total Zn and protein amount/ejaculate were not significantly different in samples collected by both technique (P < 0.05).

  7. Changes in Acute Coronary Syndrome Treatment and Prognosis After Implementation of the Infarction Code in a Hospital With a Cardiac Catheterization Unit. (United States)

    Cordero, Alberto; López-Palop, Ramón; Carrillo, Pilar; Frutos, Araceli; Miralles, Sandra; Gunturiz, Clara; García-Carrilero, María; Bertomeu-Martínez, Vicente


    Emergency care systems have been created to improve treatment and revascularization in myocardial infarction but they may also improve the management of all patients with acute coronary syndrome. A comparative study of all patients admitted with acute coronary syndrome before and after implementation of an infarction protocol. The study included 1210 patients. While the mean age was the same in both periods, the patient group admitted after implementation of the protocol had a lower prevalence of diabetes mellitus and hypertension but more active smokers and higher GRACE scores. The percentage of ST-segment elevation acute coronary syndrome (29.8%-39.5%) and coronary revascularizations (82.1%-90.1%) significantly increased among patients admitted with acute coronary syndrome, and primary angioplasty became routine (51.9%-94.9%); there was also a reduction in time to catheterization and an increase in early revascularization. The mean hospital stay was significantly shorter after implementation of the infarction protocol. In-hospital mortality was unchanged, except in high-risk patients (38.8%-22.4%). After discharge, no differences were observed between the 2 periods in cardiovascular mortality, all-cause mortality, reinfarction, or major cardiovascular complications. After implementation of the infarction protocol, the percentage of patients admitted with ST-segment elevation acute coronary syndrome and the mean GRACE score increased among patients admitted with acute coronary syndrome. Hospital stay was reduced, and primary angioplasty use increased. In-hospital mortality was reduced in high-risk patients, and prognosis after discharge was the same in both periods.

  8. Predictors of Catastrophic Adverse Outcomes in Children With Pulmonary Hypertension Undergoing Cardiac Catheterization: A Multi-Institutional Analysis From the Pediatric Health Information Systems Database. (United States)

    O'Byrne, Michael L; Glatz, Andrew C; Hanna, Brian D; Shinohara, Russell T; Gillespie, Matthew J; Dori, Yoav; Rome, Jonathan J; Kawut, Steven M


    Cardiac catheterization is the standard of care procedure for diagnosis, choice of therapy, and longitudinal follow-up of children and adults with pulmonary hypertension (PH). However, the procedure is invasive and has risks associated with both the procedure and recovery period. The purpose of this study was to identify risk factors for catastrophic adverse outcomes in children with PH undergoing cardiac catheterization. We studied children and young adults up to 21 years of age with PH undergoing 1 or more cardiac catheterization at centers participating in the Pediatric Health Information Systems database between 2007 and 2012. Using mixed-effects multivariable regression, we assessed the association between pre-specified subject- and procedure-level covariates and the risk of the composite outcome of death or initiation of mechanical circulatory support within 1 day of cardiac catheterization after adjustment for patient- and procedure-level factors. A total of 6,339 procedures performed on 4,401 patients with a diagnosis of PH from 38 of 43 centers contributing data to the Pediatric Health Information Systems database were included. The observed risk of composite outcome was 3.5%. In multivariate modeling, the adjusted risk of the composite outcome was 3.3%. Younger age at catheterization, cardiac operation in the same admission as the catheterization, pre-procedural systemic vasodilator infusion, and hemodialysis were independently associated with an increased risk of adverse outcomes. Pre-procedural use of pulmonary vasodilators was associated with reduced risk of composite outcome. The risk of cardiac catheterization in children and young adults with PH is high relative to previously reported risk in other pediatric populations. The risk is influenced by patient-level factors. Further research is necessary to determine whether knowledge of these factors can be translated into practices that improve outcomes for children with PH. Copyright © 2015 American

  10. Complications of laparoscopy. (United States)

    Hulka, J F


    This monograph documents in detail the complications of laparoscopy that have been reported in the literature with the intent of forming a background for recommendations as to prevention. It reviews the history of US surveys of physicians regarding laparoscopic complications and results of survey reports. Discussion of the prevention of complications covers: physician training, patient selection (absolute contraindications, the high risk patient, informing the patient, and suitability for local anesthesia), equipment (electrocautery, selection of laparoscope size, uterine manipulator, and maintenance of instruments), the operating room team, anesthesia, abdominal entry, trocar entry, the hazards of diagnostic procedures, minimizing complications of laparoscopic sterilization (electrocoagulation, exicsion of tubal segment, spring clip, pain during and after surgery, and selection of sterilization method), and infections. The final focus of the monograph is on the management of major complications (bowel burns -- unipolar; bowel burns -- bipolar; other injuries to the bowel; large vessel injuries; and other bleeding) and late complications (reversibility of sterilization, subsequent pregnancies -- intrauterine and ectopic, and "post-tubal syndrome"). The survey performed in the US in 1979 by the American Association of Gynecologic Laparoscopists (AAGL) reported that the unipolar technique, which had been the only technique in the early 1970s, was used by only 30% of the membership. The vast majority of the membership had converted to bipolar coagulation (43%), with a smaller number having switched to the ring (24%) and the spring clip (3%). For the 1st time, a meaningful number of both intratuerine and ectopic pregnancies was reported for all methods, allowing a relatively valid comparison of the risk of ectopic pregnancies as a function of different sterilization techniques. It appeared that the more destructive techniques (coagulation, unipolar or bipolar including

    Stojanović, J; Ilić, N; Belić, B; Zivić, L; Stanković, P; Erdevicki, L; Jovanović, S


    Orbital complications were observed in 53 patients (1.35%, n=53/3912 of all treated patients; 11.04%, n= 53/480 of hospitalized patients). Complications in the orbit can occur in 3-5% of adults with the inflammatory condition of sinuses, while the percentage in children ranges from 0.5-8%. The objective of our work was to determine the frequency of the occurence of orbital complications of the rhinosinal inflammatory origin in a group of adults and children. The retrospective analysis of patients treated of rhinosinusitis in the period 1992 to 2007, in the Clinical Center in Kragujevac. In the period of 15 years, a total number of 3912 patients were treated for inflamatory conditions of paranasal cavities. Orbital complications were found in 53 patients (1.35%, n=53/3912 of all treated patients). The number of children showing orbital complications caused by rhinosinusitis was 0.79%, while the number of adults was 1,88%. Acute rhinosinusitis in children was manifested as orbital complication in 14 patients (n=14/15, 93.33%), while 33 adults (n=33/38, 86.84%) had the exarcerbation of the chronic rhinosinusitis at the time of diagnosis of orbital complication. 80% of examined children had the maxillary and ethmoid sinus infected (n=12/15), while the adults most often had polysinusitis (n=22/38, 57.89%). In the juvenile age the most frequent complication was the cellulitis of the orbite (n=7/15, 46.66%), while in the adults it was the subperiostal absces (n=14/38, 36.84%). The adults were mostly treated surgically (n=31/38, 81.58%), while the children were treated by using conservative treatment (n=13/15, 86.67%). There were no cases of mortality. The prevention of complications is based on the adequate and timely treatment of acute sinusitis in children, as well as the curative treatment of chronical processes in adults.

  12. Complications following esophageal surgery. (United States)

    Horváth, O P; Lukács, L; Cseke, L


    Chronologically, complications can be classified as intraoperative, early, and late. The authors analyze complications according to this classification on the basis of more than 400 esophageal operations and related literary data. As regards intraoperative complications, they deal only with those occurring at transhiatal esophagectomy (e.g., tracheal tear, bleeding, pneumothorax, laryngeal nerve injury). Among the early complications, they survey the incidence of transplant necrosis and related mortality, further sequelae ensuing from subacute ischemia of the replaced organ and analyze in detail the questions which arise regarding anastomotic leakage. Firstly, they deal with those causative factors that influence the frequency of anastomotic insufficiency, such as the technical "know-how" of anastomosis making (e.g., one layer vs two layers; stapling or manual suture; interrupted or running suture), the way of replacement using whole stomach or tube-stomach and the consequences originating from the route of replacement (e.g., anterior or posterior mediastinal route). Incidence and management of chylothorax are also dealt with. While dealing with late complications, the authors give a detailed comment on anastomotic strictures and also other factors facilitating the development of late dysphagia, such as peptic stricture and tumor of the organ remnant. Finally, some cases successfully treated by surgery are presented (skin-tube formation in cases following transplant necrosis; abolition of a pharyngogastric anastomosis stricture using a free jejunal transplant and surgical solution of an anastomotic stricture from median sternotomy approach).

  13. Anticoagulation in pregnancy complications. (United States)

    Middeldorp, Saskia


    Women with acquired and inherited thrombophilia are thought to be at increased risk for pregnancy complications, including recurrent pregnancy loss and, depending on the type of thrombophilia, severe preeclampsia. This review discusses the associations between the types of thrombophilia and types of complications, as well as the currently available clinical trial evidence regarding the use of aspirin and heparin to prevent these pregnancy complications. In women with antiphospholipid syndrome, guidelines recommend prescribing aspirin and heparin to women with recurrent miscarriage. The same regimen is suggested for late pregnancy complications by some, but not all, experts. Aspirin or low-molecular-weight heparin to improve pregnancy outcome in women with unexplained recurrent miscarriage has no benefit and should not be prescribed. Whether anticoagulant therapy prevents recurrent miscarriage in women with inherited thrombophilia or in women with severe pregnancy complications remains controversial because of inconsistent results from trials. Aspirin modestly decreases the risk of severe preeclampsia in women at high risk. © 2014 by The American Society of Hematology. All rights reserved.

  15. Complications of ERCP. (United States)

    Talukdar, Rupjyoti


    Even though considered safe, endoscopic retrograde cholangiopancreatography (ERCP) is among the endoscopic procedures associated with the highest rate of complications. Post ERCP pancreatitis (PEP) is the most common complication of ERCP. Several independent risk factors have been associated with PEP. Prophylactic PD stenting has been shown to be highly effective in preventing PEP. More recent studies have suggested that NSAIDs, especially rectal indomethacin, could by itself be effective in preventing PEP. However, head to head RCTs comparing PD stents with NSAIDs would be required to confirm this. Other complications include ERCP induced bleeding, perforation, and cholangitis. Bleeding is related to morphological, procedural, and patient related factors. Early identification and correction of the risk factors are of paramount importance in preventing bleeding. Risk of infection is particularly high during ERCP. It is important to ensure complete drainage of obstructed biliary system in order to reduce the risk of post-ERCP cholangitis.

  16. Nasoenteric tube complications. (United States)

    Prabhakaran, S; Doraiswamy, V A; Nagaraja, V; Cipolla, J; Ofurum, U; Evans, D C; Lindsey, D E; Seamon, M J; Kavuturu, S; Gerlach, A T; Jaik, N P; Eiferman, D S; Papadimos, T J; Adolph, M D; Cook, C H; Stawicki, S P A


    The use of nasoenteric tubes (NETs) is ubiquitous, and clinicians often take their placement, function, and maintenance for granted. NETs are used for gastrointestinal decompression, enteral feeding, medication administration, naso-biliary drainage, and specialized indications such as upper gastrointestinal bleeding. Morbidity associated with NETs is common, but frequently subtle, mandating high index of suspicion, clinical vigilance, and patient safety protocols. Common complications include sinusitis, sore throat and epistaxis. More serious complications include luminal perforation, pulmonary injury, aspiration, and intracranial placement. Frequent monitoring and continual re-review of the indications for continued use of any NET is prudent, including consideration of changing goals of care. This manuscript reviews NET-related complications and associated topics.

  18. Analyzing complicity in risk. (United States)

    Busby, Jerry


    When risks generate anger rather than fear, there is at least someone who regards the imposition of those risks as wrongdoing; and it then makes sense to speak of the involvement in producing those risks as complicity. It is particularly relevant to examine the complicity of risk bearers, because this is likely to have a strong influence on how far other actors should go in providing them with protection. This article makes a case for analyzing complicity explicitly, in parallel with normal processes of risk assessment, and proposes a framework for this analysis. It shows how it can be applied in a case study of maritime transportation, and examines the practical and theoretical difficulties of this kind of analysis. The conclusion is that the analysis has to be formative rather than summative, but that it could provide a useful way of exposing differences in the assumptions of different actors about agency and responsibility.

  19. Silicone breast implants: complications. (United States)

    Iwuagwu, F C; Frame, J D


    Silicone breast implants have been used for augmentation mammoplasty for cosmetic purposes as well as for breast reconstruction following mastectomy for more than three decades. Though the use of the silicone gel filled variety has been banned in the USA except for special cases, they continue to be available elsewhere in the world including the UK. Despite the immense benefit they provide, their usage is associated with some complications. Most of these are related to the surgery and can be reduced by good surgical management. The major complications associated with their use is adverse capsular contracture, an outcome which can be very frustrating to manage. This article reviews the commonly reported complications and suggested management alternatives.

  20. Radiation Exposure Among Scrub Technologists and Nurse Circulators During Cardiac Catheterization: The Impact of Accessory Lead Shields. (United States)

    Madder, Ryan D; LaCombe, Andrew; VanOosterhout, Stacie; Mulder, Abbey; Elmore, Matthew; Parker, Jessica L; Jacoby, Mark E; Wohns, David


    This study was performed to determine if the use of an accessory lead shield is associated with a reduction in radiation exposure among staff members during cardiac catheterization. Accessory lead shields that protect physicians from scatter radiation are standard in many catheterization laboratories, yet similar shielding for staff members is not commonplace. Real-time radiation exposure data were prospectively collected among nurses and technologists during 764 consecutive catheterizations. The study had 2 phases: in phase I (n = 401), standard radiation protection measures were used, and in phase II (n = 363), standard radiation protection measures were combined with an accessory lead shield placed between the staff member and patient. Radiation exposure was reported as the effective dose normalized to dose-area product (EDAP). Use of an accessory lead shield in phase II was associated with a 62.5% lower EDAP per case among technologists (phase I: 2.4 [4.3] μSv/[mGy × cm2] × 10-5; phase II: 0.9 [2.8] μSv/[mGy × cm2] × 10-5; p nurses (phase I: 1.1 [3.1] μSv/[mGy × cm2] × 10-5; phase II: 0.4 [1.8] μSv/[mGy × cm2] × 10-5; p nurses (36.4% reduction; 95% confidence interval: 19.7% to 49.6%; p nurses and technologists.

    Šuchaň, M; Horňák, M; Kaliarik, L; Krempaská, S; Koštialová, T; Kovaľ, J


    Orbital complications categorised by Chandler are emergency. They need early diagnosis and agresive treatment. Stage and origin of orbital complications are identified by rhinoendoscopy, ophtalmologic examination and CT of orbite and paranasal sinuses. Periorbital cellulitis and early stage of orbital cellulitis can be treated conservatively with i. v. antibiotics. Monitoring of laboratory parameters and ophtalmologic symptoms is mandatory. Lack of improvement or worsening of symptoms within 24-48 hours and advanced stages of orbital complications are indicated for surgery. The purpose of the study is to evaluate epidemiology, clinical features and management of sinogenic orbital complications. Retrospective data of 8 patients with suspicion of orbital complication admited to hospital from 2008 to 2013 were evaluated. Patients were analyzed in terms of gender, age, CT findings, microbiology, clinical features, stage and treatment. Male and female were afected in rate 1,66:1. Most of patients were young adult in 3rd. and 4th. decade of life (62,5 %). Acute and chronic sinusitis were cause of orbital complication in the same rate. The most common origin of orbital complication was ethmoiditis (62,5 %), than maxillary (25 %) and frontal (12,5 %) sinusitis. Polysinusitis with affection of ethmoidal, maxillary and frontal sinuses (75 %) was usual CT finding. Staphylococcus epidermidis and Staphylococcus aureus were etiological agens in half of cases. Periorbital oedema (100 %), proptosis, chemosis (50 %), diplopia and glaucoma (12,5 %) were observed. Based on examinations, diagnosis of periorbital oedema/preseptal cellulitis was made in 3 (37,5 %), orbital cellulitis in 3 (37,5 %) and subperiosteal abscess in 2 cases (25 %). All patients underwent combined therapy - i. v. antibiotics and surgery within 24 hours. Eradication of disease from ostiomeatal complex (OMC), drainage of affected sinuses and drainage of subperiosteal abscess were done via fuctional endonasal

  2. Complications of cosmetic tattoos. (United States)

    De Cuyper, Christa


    Cosmetic tattoos, which are better known as permanent make-up, have become popular in the last decades. This same procedure can be used to camouflage pathological skin conditions, to mask scars and to complete the aesthetic results of plastic and reconstructive surgeries. The risks and complications of tattooing procedures include infections and allergic reactions. Scarring can occur. Fanning and fading of the colorants and dissatisfaction with colour and shape are not unusual. Different lasers can offer solutions for the removal of unwanted cosmetic tattoos, but complications due to the laser treatment, such as paradoxical darkening and scarring, can arise. © 2015 S.

  4. Anesthetic Complications in Pregnancy. (United States)

    Hoefnagel, Amie; Yu, Albert; Kaminski, Anna


    Anesthesia complications in the parturient can be divided into 2 categories: those related to airway manipulation and those related to neuraxial anesthesia. Physiologic changes of pregnancy can lead to challenging intubating conditions in a patient at risk of aspiration. Neuraxial techniques are used to provide analgesia for labor and anesthesia for surgical delivery. Therefore, complications associated with neuraxial techniques are often seen in this population. In the event of maternal cardiac arrest, modification to advanced cardiac life support algorithms must be made to accommodate the gravid uterus and to deliver the fetus if return of maternal circulation is not prompt.

    Full Text Available Desde 1993 hemos recurrido al cateterismo venoso central percutáneo para posibilitar un tratamiento efectivo en el recién nacido críticamente enfermo. Realizamos un estudio descriptivo, que incluyó a todos los pacientes consecutivos a quienes se les realizó CVCP y que estuvieron ingresados en el Servicio de Neonatología del Hospital Pediátrico Universitario «Juan M. Márquez». Se realiza una revisión retrospectiva desde junio de 1993 hasta marzo de 1995 y desde entonces en forma prospectiva hasta febrero de 2001. Se recogieron distintas variables de estudio relacionadas con preferencias, indicaciones, condiciones en su ejecución y complicaciones o accidentes por el CVCP. Se realizaron 148 intentos de CVCP en 114 pacientes. El porcentaje de éxitos por intentos fue de 66,9 % y por pacientes de 86,8 %. Se intentó realizar el cateterismo principalmente en la vena femoral (77,0 %, más frecuentemente del lado derecho (49,3 %. El porcentaje de éxitos del CVCP fue similar entre las tentativas de cateterismo por las venas femorales y las subclavias (p = 0,90, y entre los intentos por el lado derecho en comparación con el izquierdo, para los grupos venosos femoral y subclavia (p = 0,29 y p = 0,89. El CVCP se decidió principalmente ante la presencia de sepsis o de meningitis. Las complicaciones más frecuentes relacionadas con la inserción del catéter fueron la hemorragia en 28 pacientes (24,6 % y la punción de una arteria en 10 recién nacidos (8,8 %. Tras la inserción del catéter lo más común fue la oclusión (12 pacientes; 12,1 % y el edema de la extremidad (11 pacientes. Solo un paciente tuvo sepsis relacionada con el catéter y otro, taponamiento cardíaco por hidropericardio. Hubo un fallecido, a causa de un taponamiento cardíaco, complicación del CVCP (0,9 %. El CVCP es un procedimiento necesario en pacientes que habitualmente tienen una condición crítica. La técnica de ejecución recaba entrenamiento, pero definitivamente se pueden alcanzar tasas de éxito de inserción del catéter por paciente elevadas. La vena femoral, y particularmente del lado derecho, resultó en el sitio de preferencia anatómico para el CVCP, sin ofrecer ventajas de éxito sobre otras venas de acceso común en niños. Este procedimiento solo debe indicarse cuando sea imperioso, de acuerdo a la situación del caso y enfermedad de base del paciente, pues pueden ocurrir complicaciones.

  6. Development of a Veterans Affairs hybrid operating room for transcatheter aortic valve replacement in the cardiac catheterization laboratory. (United States)

    Shunk, Kendrick A; Zimmet, Jeffrey; Cason, Brian; Speiser, Bernadette; Tseng, Elaine E


    Transcatheter aortic valve replacement (TAVR) revolutionized the treatment of aortic stenosis. Developing a TAVR program with a custom-built hybrid operating room (HOR) outside the surgical operating room area poses unique challenges in Veterans Affairs (VA) institutions. To present the process by which the San Francisco VA Medical Center developed a VA-approved TAVR program, in which an HOR exists in a cardiac catheterization laboratory, as a guideline for future programs. Retrospective review of each required approval process for developing an HOR in a cardiac catheterization laboratory in a VA designated for complex surgery. Participants included San Francisco VA Medical Center health care professionals and individuals responsible for new program initiation in VA institutions. External reviews by industry vendors, the VA Central Office, and the Office for Construction, Facilities, and Management and an internal Healthcare Failure Mode and Effect Analysis. The timeline for each process. Developing a TAVR program required vetting and approval from industry vendors, who provided training and expertise. Architectural plans for construction of the HOR began in 2010-2011, followed by approval from Edwards Lifesciences, Inc, in 2012 and fundamentals training on February 8 and 9, 2013. Following a pilot launch of the first VA TAVR program at the Houston VA Medical Center, subsequent programs were required to submit a plan to the VA Central Office for proposed restructuring of their clinical programs. After the San Francisco VA Medical Center proposal submission on February 3, 2013, a site visit consisting of a National Chief of Catheterization Laboratory Managers, a cardiac surgeon, and an interventional cardiologist with TAVR experience was conducted on April 12, 2013. During construction, HOR plans were inspected by the Office for Construction, Facilities, and Management followed by on-site inspection on August 8, 2013, to assess the adequacy of the HOR, newly built

  7. 1. Dose reduction of occupational exposure in cardiac catheterization and angiography

    Energy Technology Data Exchange (ETDEWEB)

    Saito, Yoshimi [Kyushu Kosei Nenkin Hospital, Kitakyushu, Fukuoka (Japan); Matsumoto, Kunihiro; Fujihashi, Hiroshi; Umeda, Kazuhiro


    Occupational exposure to scattered radiation and protective equipment was assessed in 4 medical institutions in Kyushu, Japan. The areas where scattered radiation occurred, the scattered radiation dose in the operator's position, fluoroscopy time, the number of cinematography sessions, and annual number of patients were assessed, and the annual scattered radiation dose to the operator was estimated. Approximately 90% of scattered radiation was generated by the subject and the collimator. Measurement of scattered radiation during coronary arteriography yielded a dose of 255-1200 [{mu}Sv/hr.] during fluoroscopy and 3.8-26.7 [{mu}Sv/10 sec.] during radiography. The duration of fluoroscopy for ablation was much longer than during general examinations and PTCA, suggesting a possible contribution to occupational exposure. The data for the past 5 years show no marked change in total number of catheterizations, but the number of ablations has rapidly increased. Ablation requires specific skills, and thus it is frequently performed by only a few staff members, resulting in exposure being concentrated in a few specific persons. The estimated doses of scattered radiation to the eyes and thyroid gland, which are assumed to be the most highly exposed sites, were 116.2 [mSv/year] during fluoroscopy and 8.9 [mSv/year] during radiography, for a total of 125.1 [mSv/year]. This dose is very close to the maximum occupational exposure dose recommended by International Commission on Radiological Protection (ICRP), i.e., 150 [mSv/year]. A protective device that does not impose a burden on the operator or limit the functions of x-ray units was installed on top of the examining table as a measure to reduce the occupational dose. In an experiment using this device the scattered radiation dose during inguinal puncture decreased from 0.8 [mSv/hr.] to 0.02 [mSv/hr.], and the shielding rate was 2.5%. The dose was reduced 97.5%. The authors conclude that radiological personnel must make

  8. Effectiveness of the implementation of a simple radiation reduction protocol in the catheterization laboratory

    Background and purpose: A reduction in radiation doses at the catheterization laboratory, maintaining the quality of procedures is essential. Our objective was to analyze the results of a simple radiation reduction protocol at a high-volume interventional cardiology unit. Methods: We analyzed 1160 consecutive procedures: 580 performed before the implementation of the protocol and 580 after it. The protocol consisted in: the reduction of the number of ventriculographies and aortographies, the optimization of the collimation and the geometry of the X ray tube-patient-receptor, the use of low dose-rate fluoroscopy and the reduction of the number of cine sequences using the software “last fluoroscopy hold”. Results: There were no significant differences in clinical baseline features or in the procedural characteristics with the exception of a higher percentage of radial approach (30.7% vs 69.6%; p < 0.001) and of percutaneous coronary interventions of chronic total occlusions after the implementation of the protocol (2.1% vs 6.7%; p = 0,001). Angiographic success was similar during both periods (98.3% vs 99.2%; p = 0.2). There were no significant differences between both periods regarding the overall duration of the procedures (26.9 vs 29.6 min; p = 0.14), or the fluoroscopy time (13.3 vs 13.2 min; p = 0.8). We observed a reduction in the percentage of procedures with ventriculography (80.9% vs 7.1%; p < 0.0001) or aortography (15.4% vs 4.4%; p < 0.0001), the cine runs (21.8 vs 6.9; p < 0.0001) and the dose–area product (165 vs 71 Gyxcm{sup 2}; p < 0.0001). Conclusions: With the implementation of a simple radiation reduction protocol, a 57% reduction of dose–area product was observed without a reduction in the quality or the complexity of procedures. - Highlights: • This simple protocol can achieve a reduction in dose–area product of 57%. • It does not interfere with the quality or complexity of the procedures. • Full advantage of “Last Fluoroscopy

  9. Chronic Osteomyelitis of Clavicle in a Neonate: Report of Morbid Complication of Adjoining MRSA Abscess. (United States)

    Suranigi, Shishir Murugharaj; Joshi, Manoj; Deniese, Pascal Noel; Rangasamy, Kanagasabai; Najimudeen, Syed; Gnanadoss, James J


    Osteomyelitis of clavicle is rare in neonates. Acute osteomyelitis of clavicle accounts for less than 3% of all osteomyelitis cases. It may occur due to contiguous spread, due to hematogenous spread, or secondary to subclavian catheterization. Chronic osteomyelitis may occur as a complication of residual adjoining abscess due to methicillin resistant staphylococcus aureus (MRSA) sepsis. We report a newborn female with right shoulder abscess that developed chronic clavicular osteomyelitis in follow-up period after drainage. She required multiple drainage procedures and was later successfully managed with bone curettage and debridement. We report this case to highlight that a MRSA abscess may recur due to residual infection from a chronic osteomyelitis sinus. It may be misdiagnosed as hypergranulation tissue of nonhealing wound leading to inappropriate delay in treatment. High index of suspicion, aggressive initial management, and regular follow-up are imperative to prevent this morbid complication.

  12. Trans-ulnar catheterization and coronary interventions: From technique to outcomes. (United States)

    Sattur, Sudhakar; Singh, Maninder; Kaluski, Edo


    The ulnar artery is similar in size to the radial artery, however it is more difficult to palpate and access. For those physicians who mastered trans-ulnar access (TUA) this access site serves as an alternative to trans radial access (TRA) when the radial artery access is rendered suboptimal (by palpation, ultrasound examination or previous procedural records) or when encountering TRA difficulties or failure. The manuscript describes the anatomy, suggested technique, procedural success and complications associated with TUA. Data from single center registries and randomized studies show that TUA has a lower and more variable success rate than TRA, however these 2 approaches carry similar safety profile and complications rates. The authors suggest that interventionalists should consider, learn and master TUA to maintain higher success rate of wrist based interventions while avoiding the potential complications, discomfort and costs of trans-femoral approach.

  15. Cardiovascular Complications of Pregnancy (United States)

    Gongora, Maria Carolina; Wenger, Nanette K.


    Pregnancy causes significant metabolic and hemodynamic changes in a woman’s physiology to allow for fetal growth. The inability to adapt to these changes might result in the development of hypertensive disorders of pregnancy (hypertension, preeclampsia or eclampsia), gestational diabetes and preterm birth. Contrary to previous beliefs these complications are not limited to the pregnancy period and may leave permanent vascular and metabolic damage. There is in addition, a direct association between these disorders and increased risk of future cardiovascular disease (CVD, including hypertension, ischemic heart disease, heart failure and stroke) and diabetes mellitus. Despite abundant evidence of this association, women who present with these complications of pregnancy do not receive adequate postpartum follow up and counseling regarding their increased risk of future CVD. The postpartum period in these women represents a unique opportunity to intervene with lifestyle modifications designed to reduce the development of premature cardiovascular complications. In some cases it allows early diagnosis and treatment of chronic hypertension or diabetes mellitus. The awareness of this relationship is growing in the medical community, especially among obstetricians and primary care physicians, who play a pivotal role in detecting these complications and assuring appropriate follow up.

  16. Treatment of complicated grief

    Directory of Open Access Journals (Sweden)

    Rita Rosner


    Full Text Available Following the death of a loved one, a small group of grievers develop an abnormal grieving style, termed complicated or prolonged grief. In the effort to establish complicated grief as a disorder in DSM and ICD, several attempts have been made over the past two decades to establish symptom criteria for this form of grieving. Complicated grief is different from depression and PTSD yet often comorbid with other psychological disorders. Meta-analyses of grief interventions show small to medium effect sizes, with only few studies yielding large effect sizes. In this article, an integrative cognitive behavioral treatment manual for complicated grief disorder (CG-CBT of 25 individual sessions is described. Three treatment phases, each entailing several treatment strategies, allow patients to stabilize, explore, and confront the most painful aspects of the loss, and finally to integrate and transform their grief. Core aspects are cognitive restructuring and confrontation. Special attention is given to practical exercises. This article includes the case report of a woman whose daughter committed suicide.

  17. Neurologic complications of alcoholism. (United States)

    Noble, James M; Weimer, Louis H


    This review serves as an overview of neurologic conditions associated with alcohol abuse or withdrawal, including epidemiology, clinical symptoms, diagnostic approach, and treatment. Frequent alcohol abuse and frank alcoholism are very common among adults in the United States. Although rates decline with each decade, as many as 10% of the elderly drink excessively. Given the ubiquitous nature of alcoholism in society, its complications have been clinically recognized for generations, with recent advances focusing on improved understanding of ethanol's biochemical targets and the pathophysiology of its complications. The chronic effects of alcohol abuse are myriad and include neurologic complications through both direct and indirect effects on the central and peripheral nervous systems. These disorders include several encephalopathic states related to alcohol intoxication, withdrawal, and related nutritional deficiencies; acute and chronic toxic and nutritional peripheral neuropathies; and myopathy. Although prevention of alcoholism and its neurologic complications is the optimal strategy, this article reviews the specific treatment algorithms for alcohol withdrawal and its related nutritional deficiency states.

  19. Medical complications following splenectomy. (United States)

    Buzelé, R; Barbier, L; Sauvanet, A; Fantin, B


    Splenectomy is attended by medical complications, principally infectious and thromboembolic; the frequency of complications varies with the conditions that led to splenectomy (hematologic splenectomy, trauma, presence of portal hypertension). Most infectious complications are caused by encapsulated bacteria (Meningococcus, Pneumococcus, Hemophilus). These occur mainly in children and somewhat less commonly in adults within the first two years following splenectomy. Post-splenectomy infections are potentially severe with overwhelming post-splenectomy infection (OPSI) and this justifies preventive measures (prophylactic antibiotics, appropriate immunizations, patient education) and demands prompt antibiotic management with third-generation cephalosporins for any post-splenectomy fever. Thromboembolic complications can involve both the caval system (deep-vein thrombophlebitis, pulmonary embolism) and the portal system. Portal vein thrombosis occurs more commonly in patients with myeloproliferative disease and cirrhosis. No thromboembolic prophylaxis is recommended apart from perioperative low molecular weight heparin. However, some authors choose to prescribe a short course of anti-platelet medication if the post-splenectomy patient develops significant thrombocytosis. Thrombosis of the portal or caval venous system requires prolonged warfarin anticoagulation for 3 to 6 months. Finally, some studies have suggested an increase in the long-term incidence of cancer in splenectomized patients. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

  20. Cardiovascular Complications of Pregnancy

    Directory of Open Access Journals (Sweden)

    Maria Carolina Gongora


    Full Text Available Pregnancy causes significant metabolic and hemodynamic changes in a woman’s physiology to allow for fetal growth. The inability to adapt to these changes might result in the development of hypertensive disorders of pregnancy (hypertension, preeclampsia or eclampsia, gestational diabetes and preterm birth. Contrary to previous beliefs these complications are not limited to the pregnancy period and may leave permanent vascular and metabolic damage. There is in addition, a direct association between these disorders and increased risk of future cardiovascular disease (CVD, including hypertension, ischemic heart disease, heart failure and stroke and diabetes mellitus. Despite abundant evidence of this association, women who present with these complications of pregnancy do not receive adequate postpartum follow up and counseling regarding their increased risk of future CVD. The postpartum period in these women represents a unique opportunity to intervene with lifestyle modifications designed to reduce the development of premature cardiovascular complications. In some cases it allows early diagnosis and treatment of chronic hypertension or diabetes mellitus. The awareness of this relationship is growing in the medical community, especially among obstetricians and primary care physicians, who play a pivotal role in detecting these complications and assuring appropriate follow up.

    Smoliar, A N; Radchenko, Iu A; Nefedova, G A; Abakumov, M M


    The aim of the study was to analyze esophageal stenting complications in case of cancer and benign diseases. It was investigated complications in 8 patients in terms from 7 days to 1 year after intervention. In 4 patients esophageal stenting was performed for constrictive esophageal cancer and compression with pulmonary cancer metastases into mediastinal lymphatic nodes. 2 patients had esophageal stenting for post-tracheostomy tracheo-esophageal fistula, 1 patient - for spontaneous esophageal rupture, 1 patient - for post-burn scar narrowing of esophagus and output part of the stomach. Severe patients' condition with tumor was determined by intensive esophageal bleeding in 2 cases, bilateral abscessed aspiration pneumonia, tumor bleeding, blood aspiration (1 case), posterior mediastinitis (1 case). Severe patients' condition with benign disease was associated with decompensated esophageal narrowing about proximal part of stent (1 case), increase of tracheo-esophageal fistula size complicated by aspiration pneumonia (1 case), stent migration into stomach with recurrence of esophago-mediastino-pleural fistula and pleural empyema (1 case), decompensated narrowing of esophagus and output part of the stomach (1 case). Patients with cancer died. And patients with benign diseases underwent multi-stage surgical treatment and recovered. Stenting is palliative method for patients with esophageal cancer. Patients after stenting should be under outpatient observation for early diagnosis of possible complications. Esophageal stenting in patients with benign diseases should be performed only by life-saving indications, in case of inability of other treatment and for the minimum necessary period.

  4. Renal posttransplant's vascular complications

    Directory of Open Access Journals (Sweden)

    Bašić Dragoslav


    Full Text Available INTRODUCTION Despite high graft and recipient survival figures worldwide today, a variety of technical complications can threaten the transplant in the postoperative period. Vascular complications are commonly related to technical problems in establishing vascular continuity or to damage that occurs during donor nephrectomy or preservation [13]. AIM The aim of the presenting study is to evaluate counts and rates of vascular complications after renal transplantation and to compare the outcome by donor type. MATERIAL AND METHODS A total of 463 kidneys (319 from living related donor LD and 144 from cadaveric donor - CD were transplanted during the period between June 1975 and December 1998 at the Urology & Nephrology Institute of Clinical Centre of Serbia in Belgrade. Average recipients' age was 33.7 years (15-54 in LD group and 39.8 (19-62 in CD group. Retrospectively, we analyzed medical records of all recipients. Statistical analysis is estimated using Hi-squared test and Fischer's test of exact probability. RESULTS Major vascular complications including vascular anastomosis thrombosis, internal iliac artery stenosis, internal iliac artery rupture obliterant vasculitis and external iliac vein rupture were analyzed. In 25 recipients (5.4% some of major vascular complications were detected. Among these cases, 22 of them were from CD group vs. three from LD group. Relative rate of these complications was higher in CD group vs. LD group (p<0.0001. Among these complications dominant one was vascular anastomosis thrombosis which occurred in 18 recipients (17 from CD vs. one from LD. Of these recipients 16 from CD lost the graft, while the rest of two (one from each group had lethal outcome. DISCUSSION Thrombosis of renal allograft vascular anastomosis site is the most severe complication following renal transplantation. In the literature, renal allograft thrombosis is reported with different incidence rates, from 0.5-4% [14, 15, 16]. Data from the

  6. Subcutaneous lidocaine delivered by jet-injector for pain control before IV catheterization in the ED: the patients' perception and preference. (United States)

    Peter, David J; Scott, John P; Watkins, Henry C; Frasure, Heidi E


    To evaluate patients' perceptions and preferences concerning pain control during intravenous (IV) catheterization, a sample of 50 adult patients received subcutaneous lidocaine (0.2 mL 1%) by jet injector, or no anesthetic with a sham injection before IV catheterization. Visual analog scale (VAS), pain intensity score (PIS), and adverse reactions were recorded. A significant difference existed in the scores of patients who received lidocaine versus those who did not VAS (P <.001) PIS (P <.004). Patients' receiving lidocaine via jet-injector experienced more minor and potentially preventable adverse effects such as mild bruising and trauma to the veins. Patients in both groups (84% overall) preferred local anesthesia based on this experience. Using the jet-injector to provide local anesthesia before IV catheterization in the ED is effective, fast, and does not require sharps disposal and handling precautions.

  7. Neurological complications of chickenpox

    Directory of Open Access Journals (Sweden)

    Girija A


    Full Text Available Aim: To assess the neurological complications of chickenpox with prognosis. Background: The neurological complications occur in 0.03% of persons who get chickenpox. There is no universal vaccination against chicken pox in India. Most patients prefer alternate modalities of treatment. Hence these complications of chickenpox are likely to continue to occur. Study Design: A prospective study was conducted for 2 years (from March 2002 on the admitted cases with neurological complications after chickenpox (with rash or scar. Patients were investigated with CT/MRI, CSF study, EEG and nerve conduction studies and hematological workup. They were followed-up for 1 year and outcome assessed using modified Rankin scale. Results: The latency for the neurological complications was 4-32 days (mean: 16.32 days. There were 18 cases: 10 adults (64% and 8 children (36%. Cerebellar ataxia (normal CT/MRI was observed in 7 cases (32% (mean age: 6.85 years. One patient (6 years had acute right hemiparesis in the fifth week due to left capsular infarct. All these cases spontaneously recovered by 4 weeks. The age range of the adult patients was 13-47 years (mean: 27 years. The manifestations included cerebellar and pyramidal signs (n-4 with features of demyelination in MRI who recovered spontaneously or with methylprednisolone by 8 weeks. Patient with encephalitis recovered in 2 weeks with acyclovir. Guillain Barre syndrome of the demyelinating type (n-2 was treated with Intravenous immunoglobulin (IVIG and they had a slow recovery by a modified Rankin scale (mRs score of 3 and 2 at 6 months and 1 year, respectively. One case died after hemorrhage into the occipital infarct. There were two cases of asymmetrical neuropathy, one each of the seventh cranial and brachial neuritis. Conclusion: Spontaneous recovery occurs in post-chickenpox cerebellar ataxia. Rarely, serious complications can occur in adults. The demyelinating disorders, either of the central or peripheral

  8. Invasive treatment of non-ST-segment elevation acute coronary syndrome: cardiac catheterization/revascularization for all? (United States)

    Swahn, Eva; Alfredsson, Joakim


    Patients admitted to hospital with symptoms and signs of non-ST-segment elevation acute coronary syndromes have different risk profiles and are in need of an individualized approach that takes into consideration not only age and sex but also comorbidities such as diabetes, renal failure, hypertension, heart failure, peripheral artery disease, earlier revascularization, etc. According to evidence-based medicine and as documented in current guidelines, there is currently evidence for early catheterization and, if feasible, revascularization in high-risk patients, especially in men. Nevertheless, because of a lack of definitive evidence, there is uncertainty about treating women in the same way. Because women are usually older and have more comorbidities, they are frailer and revascularization should be indicated with greater caution. There is no evidence that catheterization as such is worse for women than for men; however, for both men and women with low risk, a less invasive approach, such as coronary computed tomography angiography, could be considered as a first diagnostic tool.

  9. Safety and efficacy of distal perfusion catheterization to prevent limb ischemia after common femoral artery cannulation for extracorporeal membrane oxygenation

    Energy Technology Data Exchange (ETDEWEB)

    Jeon, Chang Ho; Seong, Nak Jong; Yoon, Chang Jin [Dept. of Radiology, Seoul National University Bundang Hospital, Seongnam (Korea, Republic of)


    The extracorporeal membrane oxygenation (ECMO) cannula has the potential for obstructing flow to the lower limb, thus causing severe ischemia and possible limb loss. We evaluated the safety and clinical efficacy of percutaneous distal perfusion catheterization in preventing limb ischemia. Between March 2013 and February 2015, 28 patients with distal perfusion catheterization after ECMO were included in this retrospective study. The technical success was evaluated by Doppler ultrasound at the popliteal level after saline injection via distal perfusion catheter. Clinical success was assessed when at least one of the following conditions was met: restoration of continuous peripheral limb oximetry value or presence of distal arterial pulse on Doppler ultrasound evaluation or resolution of early ischemic sign after connecting the catheter with ECMO. Twenty-six patients with early ischemia were successfully cannulated with a distal perfusion catheter (92.8%). Clinical success was achieved in 12/28 (42.8%) patients; 8/10 (80.0%) patients with survival duration exceeding 7 days and 4/18 (22.2%) patients with survival duration less than 7 days, respectively. A percutaneous distal perfusion catheter placement was a feasible tool with safety and efficacy in preventing lower limb ischemia for patients with prolonged common femoral arterial cannulation for ECMO.

  10. Gastrointestinal Complications of Obesity (United States)

    Camilleri, Michael; Malhi, Harmeet; Acosta, Andres


    Obesity usually is associated with morbidity related to diabetes mellitus and cardiovascular diseases. However, there are many gastrointestinal and hepatic diseases for which obesity is the direct cause (eg, nonalcoholic fatty liver disease) or is a significant risk factor, such as reflux esophagitis and gallstones. When obesity is a risk factor, it may interact with other mechanisms and result in earlier presentation or complicated diseases. There are increased odds ratios or relative risks of several gastrointestinal complications of obesity: gastroesophageal reflux disease, erosive esophagitis, Barrett’s esophagus, esophageal adenocarcinoma, erosive gastritis, gastric cancer, diarrhea, colonic diverticular disease, polyps, cancer, liver disease including nonalcoholic fatty liver disease, cirrhosis, hepatocellular carcinoma, gallstones, acute pancreatitis, and pancreatic cancer. Gastroenterologists are uniquely poised to participate in the multidisciplinary management of obesity as physicians caring for people with obesity-related diseases, in addition to their expertise in nutrition and endoscopic interventions.

  12. Thrombophilia and Pregnancy Complications

    Directory of Open Access Journals (Sweden)

    Louise E. Simcox


    Full Text Available There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction. Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

  15. Orbital complications of rhinosinusitis. (United States)

    Sijuwola, Oo; Adeyemo, Aa; Adeosun, Aa


    Suppurative extension of rhinosinusitis to the orbit is a complication that often results from delay in diagnosis and, or inadequate treatment. These complications may range from preseptal cellulitis, orbital cellulitis, orbital abscesses, and subperiosteal abscesses to intracranial extension with a threat to both vision and life. This study aims to review the clinical profile, treatment modalities and outcome of orbital complications of rhinosinusitis in Ibadan, Nigeria. A retrospective review of the charts of patients with orbital complications of rhinosinusitis managed in the departments of Otorhinolaryngology and Ophthalmology, University College Hospital, Ibadan over a five year period (Feb 2002- Jan 2007) was carried out .The diagnosis of rhinosinusitis was based on history, physical examination, plain x ray and CT scan findings and antral puncture. Demographic data, clinical presentation and treatment were evaluated. A total of 24 patients were reviewed in the study. There were 13males and 11females (M/F, 1:1). The age range was 8months to 75years, 14 (58.3%) patients were children and while 10 (41.7%) patients were adults. 75% of the patients were seen during the dry season (November to February). The duration of symptoms ranged from one day to three weeks. Involvement of one eye occurred in 14 patients (58.3%); right eye (4), left eye (10). Both eyes were involved in 10 patients (41.7%). Non-axial proptosis was seen in 8 patients (33.3%). It was infero-lateral in 6 patients (25%) and infero-nasal in two (8.3%) patients. Orbital cellulitis was seen in 10 (41.7%) patients, 6 (25%) patients had preseptal cellulitis while 8 (33%) patients had orbital abscess. Cavernous sinus thrombosis was seen in 3 (12.5%) patients. The cases with preseptal and orbital cellulitis were effectively managed by intravenous antibiotics. Orbital abscesses were drained surgically with complete resolution. Sinus surgical procedures were done in 10(41.7%) patients. This group of

    Full Text Available Harold Merle1, Jérôme Guyomarch1, Jean-Christophe Joyaux1, Maryvonne Dueymes2, Angélique Donnio1, Nicole Desbois2 1Department of Ophthalmology, 2Laboratory of Microbiology, University Hospital of Fort-de-France, Martinique, French West Indies Abstract: The authors describe a case of keratomycosis that appeared after the exeresis of a pterygium. A 48-year-old patient had been referred with a red right eye associated with an abscess of the cornea along the ablation zone of the pterygium. The surgery had been performed a month beforehand. The abscess was 6 mm high and 4 mm wide. The authors instigated a treatment that included amphotericin B (0.25% after noticing a clinical aspect evoking a fungal keratitis and finding several septate filaments on direct examination. On day 10, a Fusarium dimerum was isolated on Sabouraud agar. After 15 days of treatment, the result was favorable and the size of the ulceration as well as the size of the abscess had progressively decreased. The antifungal treatment was definitively stopped at 14 weeks. Infectious-related complications of the pterygium surgery are rare and are essentially caused by bacterial agents. Secondary infections by fungus are rare. There have been two previous cases reported: one that appeared 15 years after radiotherapy and another that appeared at 3 weeks post surgery, consecutive to the use of mitomycin C. To the authors' knowledge, this is the first case of a keratomycosis due to F. dimerum reported that complicated the exeresis of a pterygium without the use of an adjuvant antihealing treatment. Pterygium surgery is a common procedure; nevertheless, ophthalmologists need to be aware of the existence of potential infectious complications. Keywords: keratitis, corneal abscess, Fusarium

  5. Pregnancy complicated with agranulocytosis. (United States)

    Wang, Hai; Sun, Jiang-Li; Zhang, Zheng-Liang; Pei, Hong-Hong


    Pregnancy is a complicated physiological process. Physiological leukocytosis often takes place and it is primarily related to the increased circulation of neutrophils, especially during the last trimester of pregnancy. Noncongenital agranulocytosis during pregnancy is rare and reported only occasionally, while in most of the cases, the agranulocytosis has already occurred prior to pregnancy or induced by identified factors such as antibiotics, antithyroid agents, or cytotoxic agents. Gestation-induced agranulocytosis has not been reported, so we present a case of gestation-induced agranulocytosis in this article. In this case, we present a Chinese woman (aged 25) in her 38th week of the first gestation who had the complication of agranulocytosis. No abnormality was detected in regular examinations before pregnancy and in the first trimester. Since the last trimester of pregnancy, the patient began to suffer from agranulocytosis and intermittent fever, the maximum being temperature 38.8°C. At admission, the neutrophil granulocytes were 0.17 × 10 L and the bone marrow biopsy showed that agranulocytosis was detected, but the levels of red blood cell and megalokaryocyte were normal. In addition, antinuclear antibodies were detected at a dilution of 1:40, but anti-dsDNA, antiphospholipid antibody, and neutrophil granulocyte antibody were negative. The patient was empirically treated as having pneumonia. We tried to use granulocyte colony-stimulating factor, γ-globulin, glucocorticoids, antibiotics, and antifungi agents to treat the patient, but her symptoms were not alleviated until the patient had a cesarean section. After 24 hours of cesarean section, the temperature and neutrophil granulocyte returned to normal. After a year of follow-up, we found that the patient and the baby were healthy. Agranulocytosis during pregnancy seems to be associated with immunosuppression induced by immunoregulations and termination of pregnancy may be effective for refractory

    Full Text Available Background: Optimal timing and mode of treatment for patients with coarctation of the aorta (COA remain controversial, particularly in children. Surgery, balloon dilatation, and stent implantation have all proven effective in the treatment of moderate or severe obstruction. The aim of this study was to investigate the complications of COA stenting angioplasty in pediatric patients. Methods: This retrospective, descriptive study was conducted on patients less than 20 years of age who underwent aortic stenting angioplasty because of congenital COA in the pediatric catheterization laboratory of Rajaie cardiovascular, medical and research Center, Tehran between 2005 and 2010. Results: A total of 26 patients (18 [65.4%] males and 9 [34.6%] females with congenital COA who had undergone aortic stenting angioplasty were recruited. Nineteen (73.1% of these patients had native COA and 7 (26.9% had recurrent COA. Most of the early complications were minor and temporary; only one patient developed early major complications. During the follow-up, whereas none of the native group patients developed late complications, in the re-COA group 28.57% of the patients had re-stenosis and 14.28% had chronic systemic hypertension, requiring drug therapy. Conclusion: Our investigation into post-stenting complications in patients with native COA and re-COA showed that endovascular stenting could be an effective and safe method, even in young patients with native COA.

    Full Text Available Inappropriate use of indwelling urinary catheters (IUCs and their related complications is one of the most important problems in hospital wards. The aim of this study was to evaluate inappropriate use of IUCs and their complications among patients in Tehran, Iran. Two hundred and six consecutive patients hospitalized in the intensive care unit (ICU as well as medical and surgical wards at the Shahid Mohammadi Hospital in Bandarabbas from September 1 to 30, 2005 and in whom IUCs were used, were studied. Data collected included age of the patients, diagnoses, reason for use of IUC and the complications related to it. Overall, 164 patients (79.6% had IUCs used appropriately while 42 of them (20.6% were catheterized unjustifiably. Inappropriate use of IUCs in the ICU, medical and surgical wards was reported in 12 (18.5%, 16 (19.0% and 14 patients (24.6%, respectively. The most common complication of IUCs was urinary tract infection, which occurred in 91 patients (44.2% and hematuria, which was seen in 3.9% of the patients. Our study suggests that inappropriate use of IUCs is prevalent, particularly in the surgical wards, and the most common complication observed was catheter-associated urinary tract infection.

  8. Management of complicated wounds. (United States)

    Hendrix, Sam M; Baxter, Gary M


    Most injuries, including those with significant tissue loss, can be successfully managed with proper therapy. With delayed healing, potential causes for the delay, such as sequestra, foreign bodies, and excessive motion,should be determined and treated to permit complete wound resolution. Horses have the innate ability to heal rapidly; however, minor injuries can quickly turn into complicated wounds, given the severity of the inciting trauma and the less than ideal environment in which the horses are housed. Wound management must focus on a combination of timely surgical and medical intervention to ensure the best potential outcome.

    Shinohara, Michi M


    Decorative tattoo is a popular practice that is generally safe when performed in the professional setting but can be associated with a variety of inflammatory, infectious, and neoplastic complications, risks that may be increased with current trends in home tattooing. Modern tattoo inks contain azo dyes and are often of unknown composition and not currently regulated for content or purity. Biopsy of most (if not all) tattoo reactions presenting to the dermatologist is recommended, given recent clusters of nontuberculous mycobacterial infections occurring within tattoo, as well as associations between tattoo reactions and systemic diseases such as sarcoidosis.

    Full Text Available Lemierre's syndrome is an anaerobic suppurative thrombophlebitis involving the internal jugular vein secondary to oropharyngeal infection. There is only one previous case report in pregnancy which was complicated by premature delivery of an infant that suffered significant neurological damage. We present an atypical case diagnosed in the second trimester with a live birth at term. By reporting this case, we hope to increase the awareness of obstetricians to the possibility of Lemierre's syndrome when patients present with signs of unabating oropharyngeal infection and pulmonary symptoms.

    Davies, S F; Sarosi, G A


    With AIDS has come a new level of T-cell immunosuppression, beyond that previously seen. The impact of the HIV pandemic on the field of fungal infections includes a major increase in the number of serious fungal infections, an increase in the severity of those infections, and even some entirely new manifestations of fungal illness. In this article fungal pulmonary complications of AIDS are discussed. T-cell opportunists including Cryptococcus neoformans and the endemic mycoses are the most important pathogens. Phagocyte opportunists, including Aspergillus species and agents of mucormycosis, are less important.

    Full Text Available Background: There is limited data about the influence of timing of cardiac surgery in relation to diagnostic angiography and/or the impact of the amount of contrast media used during angiography on the occurance of acute renal failure (ARF. Therefore, in the present study the effect of the time interval between diagnostic angiography and cardiac surgery and also the amount of contrast media used during the diagnostic procedure on the incidence of ARF after cardiac surgery was investigated. Methods: Data of 1177 patients who underwent different types of cardiac surgeries after cardiac catheterization were prospectively examined. The influence of time interval between cardiac catheterization and surgery as well as the amount of contrast agent on postoperative ARF were assessed using multivariable logistic regression. Results: The patients who progressed to ARF were more likely to have received a higher dose of contrast agent compared to the mean dose. However, the time interval between cardiac surgery and last catheterization was not significantly different between the patients with and without ARF (p = 0.05. Overall, postoperative peak creatinine was highest on day 0, then decreased and remained significantly unchanged after this period. Overall prevalence of acute renal failure during follow-up period had a changeable trend and had the highest rates in days 1 (53.57% and 6 (52.17% after surgery. Combined coronary bypass and valve surgery were the strongest predictor of postoperative ARF (OR: 4.976, CI = 1.613-15.355 and p = 0.002, followed by intra-aortic balloon pump insertion (OR: 6.890, CI = 1.482-32.032 and p = 0.009 and usage of higher doses of contrast media agent (OR: 1.446, CI = 1.033-2.025 and p = 0.031. Conclusions: Minimizing the amount of contrast agent has a potential role in reducing the incidence of postoperative ARF in patients undergoing cardiac surgery, but delaying cardiac surgery after exposure to these agents might not have

  13. Left main stent thrombosis complicated by eptifibatide-induced acute thrombocytopenia. (United States)

    Yang, Eric H; Perez, Edwin; Zhiroff, Katrine A; Burstein, Steven


    A 57-year-old man with a history of coronary artery disease and placement of an implantable cardioverter-defibrillator presented at our emergency room with an anterior ST-elevation myocardial infarction. Cardiac catheterization revealed an acutely occluded left main coronary artery, which was revascularized successfully with a bare-metal stent. Periprocedurally, the patient received aspirin, clopidogrel, unfractionated heparin, and eptifibatide. The patient was discharged a week later, but he returned to the emergency room the same day with recurrence of severe chest pain. Repeat cardiac catheterization revealed an acutely occluded stent, and the patient underwent repeat bare-metal stent placement and readministration of eptifibatide. On the next day, the patient's platelet count dropped acutely to less than 12,000/mm3. A test for heparin-induced thrombocytopenia antibody was negative. After discontinuation of eptifibatide, the patient's platelet count gradually returned to normal, and he was later discharged from the hospital with no complications. Eptifibatide-induced acute thrombocytopenia is a known but rare adverse effect. We review the handful of case reports in the medical literature, with emphasis on the prevalence, observed clinical course, and recently proposed physiologic mechanisms that probably are responsible for this phenomenon.

  14. Complications associated with orthognathic surgery (United States)


    While most patients undergo orthognathic surgery for aesthetic purposes, aesthetic improvements are most often followed by postoperative functional complications. Therefore, patients must carefully decide whether their purpose of undergoing orthognathic surgery lies on the aesthetic side or the functional side. There is a wide variety of complications associated with orthognathic surgery. There should be a clear distinction between malpractice and complications. Complications can be resolved without any serious problems if the cause is detected early and adequate treatment provided. Oral and maxillofacial surgeons must have a full understanding of the types, causes, and treatment of complications, and should deliver this information to patients who develop these complications.

  15. Epigenetic Diabetic Vascular Complications

    Directory of Open Access Journals (Sweden)

    Ali Ahmadzadeh-Amiri


    Full Text Available Diabetic vascular complications (DVC influence several vital organ systems including cardiovascular, renal, ocular and nervous systems making it a major public health problem. Although extensive researches were performed in this field, the exact mechanisms responsible for these organ damages in diabetes remain obscure. Several metabolic disturbances have been involved in its complication and change in genes associated with these pathways occurred. Gene expression to produce a biologically active protein can be controlled by transcriptional and translational alteration on the head of genes without change in nucleotide composition. These epigenetic adjustments are steady, but possibly reversible and can be transmitted to future generation. Gene expression can be regulated by three epigenetic mechanisms including DNA methylation, histone modifications and noncoding microRNAs (miRNAs activity. Epigenetic studies must be directed to better realize the role of epigenetic changes to the etiology of DVC and knowledge of epigenetic would play a pivotal role in the application of individualized medicine. Application and development of high technology sequencing combined with more sensitive and advanced methodologies for epigenome studying help to determine specific epigenetic events that stimulate gene responses in patients with diabetes mellitus.

  17. The Effect of Simulation Teaching on Baccalaureate Nursing Students' Self-confidence Related to Peripheral Venous Catheterization in Children: A Randomized Trial. (United States)

    Valizadeh, Leila; Amini, Abolghasem; Fathi-Azar, Eskandar; Ghiasvandian, Shahrzad; Akbarzadeh, Bahareh


    In recent decades, nursing instructors have tended to use simulation rather than traditional methods due to benefits such as increased self-confidence. However, little academic literature is available to verify this claim. The procedure of establishing peripheral venous catheterization in pediatric patients is of great importance. Therefore, the researchers attempted to review the effect of the simulation teaching method on nursing students' self-confidence related to peripheral venous catheterization in pediatric patients. In this trial, 45 students in the 5(th) and 6(th) semester of nursing school in the first half of school year 2012 from the Faculty of Nursing and Midwifery, Tabriz University of Medical Sciences, Iran, were randomly assigned to three groups (a control group, and two intervention groups). They were trained in establishing peripheral venous catheterization in pediatric patients through simulation teaching method and practical training. The students' self-confidence was assessed by C-Scale before and after the intervention. The students' self-confidence score showed a significant increase in the simulation group after the intervention in comparison to other groups (p = 0.03). RESULTS revealed a significant increase in self-confidence of nursing students related to peripheral venous catheterization in pediatric patients by simulation. This substantiates the assertion that simulation can improve self-confidence. Due to the low sample size, further studies with larger population are suggested.

We proposed a novel case definition and determined the epidemiology and risk factors of BSIs after CC procedure using this new definition.

  19. Transcatheter aortic valve replacement: establishing a comprehensive program model for hybrid cardiac catheterization laboratories in the Department of Veterans Affairs. (United States)

    Speiser, Bernadette; Dutra-Brice, Cynthia


    Aortic valve disease, especially aortic stenosis, becomes progressively debilitating and carries a high mortality risk if it is categorized as severe and symptomatic (J Thorac Cardiovas Surg. 2012;144(3):e29-e84). In the past, the only treatment for aortic stenosis was surgical aortic valve replacement. Surgical treatment may require several hours of cardioplegia, and if the patient has comorbidities, such as renal failure or chronic obstructive pulmonary disease, their operative mortality percentage increases.In 2011, the US Food and Drug Administration approved the use of a transcatheter aortic valve replacement (TAVR) procedure for patients who were deemed high risk or inoperative for the routine surgical aortic valve replacement surgery. More than 20, 000 TAVRs have been performed in patients worldwide since 2002 when Dr Alain Cribier performed the first-in-man TAVR (Arch Cardiovasc Dis. 2012;105(3):145-152). The Edwards Lifesciences SAPIEN XT valve and the Medtronic CoreValve are commercially available.The clinical findings and economic statistic have supported the expansion of the TAVR procedure. However, there has been considerable controversy over where the procedure is to occur and who is directly responsible for directing the TAVR care. This debate has identified barriers to the implementation of a TAVR program. The operating rooms and a cardiac catheterization laboratory are underprepared for the hybrid valve replacement therapy. Because of the barriers identified, the Department of Veterans Affairs determined a need for a systematic approach to review the programs that applied for this structural heart disease program. A centralized team was developed to ensure room readiness and staff competency. The use of the Health Failure Mode and Effects Analysis can define high-risk clinical processes and conduct a hazard analysis. Worksheets can show potential failure modes and their probabilities, along with actions and outcome measures, team collaboration

    Full Text Available Ikenna I Nnabugwu, Emeka I Udeh, Oghenekaro A Enivwenae, Fred O Ugwumba, Oyiogu F Ozoemena Urology Unit, Department of Surgery, University of Nigeria Teaching Hospital, Enugu, Nigeria Background: Clean intermittent self-catheterization is accepted worldwide as a standard of care for patients with long-standing need for urinary bladder decompression. Evidence of its routine practice in our low-resource setting is lacking, leading to increasing number of patients with a long-standing indwelling urinary catheter.Objective: To seek the opinion of patients already using indwelling catheters regarding the practice of self-catheterization.Patients and methods: Over a 4-month period, the opinion of every patient and patient’s relative that attended the regular urinary catheter clinic was sought using an intern-administered questionnaire. The data was analyzed using SPSS version 20.Results: A total of 108 patients completed the questionnaire. Age range was 16–100 years with a mean of 62.2±15.5 years. Only 30.5% of the patients had formal education beyond the primary level. The median cost for change of the indwelling catheter was 1,325 naira ($8.28 US with a range of 500–4,000 naira ($3.13–$25 USD. Analysis showed that: 70.8% of patients aged under 60 years/60.6% of those with formal education beyond primary level/61.9% of those wearing catheters for <3 months would give consent for training in self-catheterization. Higher cost of catheter change did not influence the decision to consider self-catheterization. Of the 59 patient relatives who completed the questionnaire, 63% of those younger than 50 years old and 69.2% of those with tertiary education would be willing to undertake training to administer self-catheterization.Conclusion: A select group of patients and accompanying relatives in our low-resource setting are willing to learn and practice self-catheterization.

  4. Baseline Hemodynamics and Response to Contrast Media During Diagnostic Cardiac Catheterization Predict Adverse Events in Heart Failure Patients. (United States)

    Denardo, Scott J; Vock, David M; Schmalfuss, Carsten M; Young, Gregory D; Tcheng, James E; O'Connor, Christopher M


    Contrast media administered during cardiac catheterization can affect hemodynamic variables. However, little is documented about the effects of contrast on hemodynamics in heart failure patients or the prognostic value of baseline and changes in hemodynamics for predicting subsequent adverse events. In this prospective study of 150 heart failure patients, we measured hemodynamics at baseline and after administration of iodixanol or iopamidol contrast. One-year Kaplan-Meier estimates of adverse event-free survival (death, heart failure hospitalization, and rehospitalization) were generated, grouping patients by baseline measures of pulmonary capillary wedge pressure (PCWP) and cardiac index (CI), and by changes in those measures after contrast administration. We used Cox proportional hazards modeling to assess sequentially adding baseline PCWP and change in CI to 5 validated risk models (Seattle Heart Failure Score, ESCAPE [Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness], CHARM [Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity], CORONA [Controlled Rosuvastatin Multinational Trial in Heart Failure], and MAGGIC [Meta-Analysis Global Group in Chronic Heart Failure]). Median contrast volume was 109 mL. Both contrast media caused similarly small but statistically significant changes in most hemodynamic variables. There were 39 adverse events (26.0%). Adverse event rates increased using the composite metric of baseline PCWP and change in CI (Pcontrast correlated with the poorest prognosis. Adding both baseline PCWP and change in CI to the 5 risk models universally improved their predictive value (P≤0.02). In heart failure patients, the administration of contrast causes small but significant changes in hemodynamics. Calculating baseline PCWP with change in CI after contrast predicts adverse events and increases the predictive value of existing models. Patients with elevated baseline PCWP and

  5. Reduction of operator radiation dose by a pelvic lead shield during cardiac catheterization by radial access: comparison with femoral access. (United States)

    Lange, Helmut W; von Boetticher, Heiner


    This study sought to determine the efficacy of patient pelvic lead shielding for the reduction of operator radiation exposure during cardiac catheterization via the radial access in comparison with the femoral access. Cardiac catheterization via the radial access is associated with significantly increased radiation dose to the patient and the operator. Improvements in radiation protection are needed to minimize this drawback. Pelvic lead shielding has the potential to reduce operator radiation dose. We randomly assigned 210 patients undergoing elective coronary angiography by the same operator to a radial and femoral access with and without pelvic lead shielding of the patient. Operator radiation dose was measured by a radiation dosimeter attached to the outside breast pocket of the lead apron. For radial access, operator dose decreased from 20.9 ± 13.8 μSv to 9.0 ± 5.4 μSv, p lead shielding. For femoral access, it decreased from 15.3 ± 10.4 μSv to 2.9 ± 2.7 μSv, p lead shielding significantly decreased the dose-area product-normalized operator dose (operator dose divided by the dose-area product) by the same amount for radial and femoral access (0.94 ± 0.28 to 0.39 ± 0.19 μSv × Gy(-1) × cm(-2) and 0.70 ± 0.26 to 0.16 ± 0.13 μSv × Gy(-1) × cm(-2), respectively). Pelvic lead shielding is highly effective in reducing operator radiation exposure for radial as well as femoral procedures. However, despite its use, radial access remains associated with a higher operator radiation dose. Copyright © 2012 American College of Cardiology Foundation. Published by Elsevier Inc.

  6. Does cardiac catheterization laboratory activation by electrocardiography machine auto-interpretation reduce door-to-balloon time? (United States)

    Min, Mun Ki; Ryu, Ji Ho; Kim, Yong In; Park, Maeng Real; Park, Yong Myeon; Park, Sung Wook; Yeom, Seok Ran; Han, Sang Kyoon; Kim, Yang Weon


    In an attempt to begin ST-segment elevation myocardial infarction (STEMI) treatment more quickly (referred to as door-to-balloon [DTB] time) by minimizing preventable delays in electrocardiogram (ECG) interpretation, cardiac catheterization laboratory (CCL) activation was changed from activation by the emergency physician (code heart I) to activation by a single page if the ECG is interpreted as STEMI by the ECG machine (ECG machine auto-interpretation) (code heart II). We sought to determine the impact of ECG machine auto-interpretation on CCL activation. The study period was from June 2010 to May 2012 (from June to November 2011, code heart I; from December 2011 to May 2012, code heart II). All patients aged 18 years or older who were diagnosed with STEMI were evaluated for enrollment. Patients who experienced the code heart system were also included. Door-to-balloon time before and after code heart system were compared with a retrospective chart review. In addition, to determine the appropriateness of the activation, we compared coronary angiography performance rate and percentage of STEMI between code heart I and II. After the code heart system, the mean DTB time was significantly decreased (before, 96.51 ± 65.60 minutes; after, 65.40 ± 26.40 minutes; P = .043). The STEMI diagnosis and the coronary angiography performance rates were significantly lower in the code heart II group than in the code heart I group without difference in DTB time. Cardiac catheterization laboratory activation by ECG machine auto-interpretation does not reduce DTB time and often unnecessarily activates the code heart system compared with emergency physician-initiated activation. This system therefore decreases the appropriateness of CCL activation. Copyright © 2014 Elsevier Inc. All rights reserved.

    Most laparoscopic complications occur as a result of creating and maintaining a pneumoperitoneum and the blind insertion of the first trocar. Thus, it is the complications of the laparoscopic approach rather than the complications of the laparoscopic technique for a specific condition which should be considered. The hazards and the incidences, causes, prevention and management of these complications are discussed using the experience of the author and reported data.

  9. A rare etiology of Fournier's gangrene: Pubic tubercle fracture complicated with hematoma and acute osteomyelitis

    Directory of Open Access Journals (Sweden)

    Chien-Liang Fang


    Full Text Available The etiologies of Fournier's gangrene are well described into four groups: anorectal, genitourinary, dermatologic, and idiopathic. Here, we present the case of a hematoma and acute osteomyelitis (related to a closed fracture of the pubis, which progressed to Fournier's gangrene 1 month after trauma. A 68-year-old woman was admitted to our emergency department because she had sustained a left side pubic bone fracture from a fall. On her first admission to our emergency department, conservative treatment had been prescribed; however, she was readmitted to our emergency department due to septic shock, local swelling, and pus discharge from the pubis and the left labium majus. A whole abdomen computed tomography scan revealed fluid accumulation in the left suprapubic and perineum region in addition to acute osteomyelitis of the pubis. Acute osteomyelitis-related Fournier's gangrene and sepsis were suspected; hence, she underwent urgent fasciotomy and sequestrectomy. After three rounds of sequestrectomies, partial wound reconstruction with local flap and 24-day hospitalization, she was discharged from our hospital with continuing wound care management. Conservative treatment of closed stable fractures of the pelvic bone along with bed rest is suggested by most orthopedists. However, surgical drainage of hematoma is necessary due to the poor hematoma absorption owing to pelvic fracture. The patient subsequently contracted acute osteomyelitis, a secondary infection associated with the etiology of Fournier's gangrene, particularly in the case of patients with diabetes mellitus. We concluded that this was a rare etiology of Fournier's gangrene and examined the complications of pelvic bone fracture in this context.

    Full Text Available Background: Totally implantable access port (TIAP provides reliable, long term vascular access with minimal risk of infection and allows patients normal physical activity. With wide use of ports, new complications have been encountered. We analyzed TIAP related complications and evaluated the outcomes of two different percutaneous routes of access to superior vena cava. Methods: All 172 patients who underwent port insertion with internal jugular approach (Group 1, n = 92 and subclavian approach (Group 2, n = 79 between August 2011 and May 2013 in a single center were analyzed, retrospectively. Medical records were analyzed to compare the outcomes and the occurrence of port related complications between two different percutaneous routes of access to superior vena cava. Results: Median follow-up for TIAP was 278 days (range, 1-1868. Twenty four complications were occurred (14.0%, including pneumothorax (n = 1, 0.6%, migration/malposition (n = 4, 2.3%, pinch-off syndrome (n = 4, 2.3%, malfunction (n = 2, 1.1%, infection (n = 8, 4.7%, and venous thrombosis (n = 5, 2.9%. The overall incidence was 8.7% and 20.3% in each group (p = 0.030. Mechanical complications except infectious and thrombotic complications were more often occurred in group 2 (p = 0.033. The mechanical complication free probability is significantly higher in group 1 (p = 0.040. Conclusions: We suggest that the jugular access should be chosen in patients who need long term catheterization because of high incidence of mechanical complication, such as pinch-off syndrome.

    Full Text Available Introduction: Viral croup is the most common cause of stridor in children seen at emergency room. In the absence of response to treatment with corticosteroids and nebulized adrenaline, bacterial tracheitis should be considered. Case Report: A six year-old child, was admitted in emergency room with stridor, respiratory distress and fever, with partial response to therapy with nebulized epinephrine. Ceftriaxone was prescribed for suspected bacterial laryngotracheobronchitis. Despite therapy, developed cervical cellulitis with progression to retropharyngeal abscess and mediastinitis. Good outcome after therapy with ceftriaxone, clindamycin and vancomycin. Discussion/Conclusion: The authors describe an original case of a bacterial tracheitis complicated with retropharyngeal abcess and mediastinitis, emphasizing that bacterial tracheitis is potentially life threatening, requiring a high index of suspicion for early diagnosis.

  12. Coagulation complications following trauma. (United States)

    Martini, Wenjun Z


    Traumatic injury is one of the leading causes of death, with uncontrolled hemorrhage from coagulation dysfunction as one of the main potentially preventable causes of the mortality. Hypothermia, acidosis, and resuscitative hemodilution have been considered as the significant contributors to coagulation manifestations following trauma, known as the lethal triad. Over the past decade, clinical observations showed that coagulopathy may be present as early as hospital admission in some severely injured trauma patients. The hemostatic dysfunction is associated with higher blood transfusion requirements, longer hospital stay, and higher mortality. The recognition of this early coagulopathy has initiated tremendous interest and effort in the trauma community to expand our understanding of the underlying pathophysiology and improve clinical treatments. This review discusses the current knowledge of coagulation complications following trauma.

  14. The effect of nursing interventions utilizing music therapy or sensory information on Chinese patients' anxiety prior to cardiac catheterization: a pilot study. (United States)

    Taylor-Piliae, Ruth E; Chair, Sek-Ying


    Unrelieved anxiety can produce an increase in sympathetic nervous system activity leading to an increase in cardiac workload. Nursing interventions using music therapy or sensory information among patients with coronary artery disease has resulted in anxiety reduction, though results in Chinese subjects has not previously been published. To determine the effects of using nursing interventions of music therapy or sensory information, on reducing anxiety and uncertainty, and improving negative mood among Chinese subjects immediately prior to cardiac catheterization. An experimental three-group repeated measures design for this pilot study was used. Forty-five hospitalized adults (15/group) undergoing cardiac catheterization were randomly assigned to either (1) a music therapy intervention, (2) a sensory information intervention or (3) treatment as usual (control). Anxiety, uncertainty and mood state were measured using self-reported questionnaires and physiological measures were made at baseline, post-intervention to determine their effect and post-cardiac catheterization to determine whether these interventions had any long-lasting effect. The control group was found to be significantly older (P=0.001) than the two experimental groups. Older age was associated with lower anxiety scores (r=-0.31, P=0.04 at baseline; r=-0.30, P=0.04 post-intervention; r=-0.22, P=0.15 post-cardiac catheterization). After controlling for age, the use of music therapy or sensory information did not significantly reduce anxiety, improve mood state, reduce uncertainty, decrease heart or respiratory rate among subjects undergoing cardiac catheterization. The non-significant result may have been affected by the small sample, and the social and cultural expectations regarding the public display of emotions among Chinese populations.

  15. Transvenous DSA: ECG-controlled cardial effects and venous complications after pre-atrial injection of nonionic contrast media

    Energy Technology Data Exchange (ETDEWEB)

    Arlart, I.P.; Sigel, H.


    Transvenous DSA is a diagnostic technique for ambulatory examination that is well tolerated by patients, although it is commonly known that bolus injection of contrast medium for examination of the cardiovascular system may affect the cardiovascular hemodynamic process. The prospective study described was intended to reveal in 100 patients the effects on ECG data, as well as clinical symptoms of non-tolerance of contrast medium (nonionic, with high iodine content, Iopamidol 370), applied by central pre-atrial injection. In addition, catheterization-induced complications in the venous system of the arm were studied in 130 patients. Change of heart rate was the most frequent effect observed (increase in 49% of patients pretreated with Buscopan, decrease in 36% of non-pretreated patients). The second next effects were supraventricular and ventricular ES (20%), minor prolongations of PQ and QRS intervals (14%), and ST lowering (3%), without clinical symptons. In one case, an attack of Angina pectoris was observed, another patient developed a cutane allergy. After catheterization of brachial vein, thromboses were observed in 3% of patients, as well as local inflammations in 6%, short attacks of fever in 2.3%. The complications were observed for the most part in cases where re-sterilised catheters had been used.

  16. [Postoperative complications after thoracic surgery]. (United States)

    Ferretti, G; Brichon, Py; Jankowski, A; Coulomb, M


    Postoperative complications after pneumonectomy, lobectomy, or wedge resection are relatively frequent and potentially significant. Chest radiographs and CT have a crucial role in the early detection and prompt management of these complications. The purpose of this paper is to illustrate the most frequent or severe complications, based on the timing of occurrence. Early complications include bronchopleural fistula, empyema, atelectasis, pneumonia, hemothorax, chylothorax, pulmonary edema, lobar torsion, cardiac hernia, gossypiboma and esophagopleural fistula. Late complications include bronchopleural fistula, esophagopleural fistula, postpneumonectomy syndrome, chest wall arteriovenous fistula and local tumor recurrence.

Currently, they are part of the standard medical care for oncohematologic patients. However, apart from mechanical and thrombotic complications, there are also complications associated with biofilm development inside the catheters. These biofilms increase the cost of medical assistance and extend hospitalization. The most frequently involved micro-organisms in these infections are gram-positive cocci. Many efforts have been made to understand biofilm formation within the lumen catheters, and to resolve catheter-related infection once it has been established. Apart from systemic antibiotic treatment, the use of local catheter treatment (ie, antibiotic lock technique is widely employed. Many different antimicrobial options have been tested, with different outcomes, in clinical and in in vitro assays. The stability of antibiotic concentration in the lock solution once instilled inside the catheter lumen remains unresolved. To prevent infection, it is mandatory to perform hand hygiene before catheter insertion and manipulation, and to disinfect catheter hubs, connectors, and injection ports before accessing the catheter. At present, there are still unresolved questions regarding the best antimicrobial agent for catheter-related bloodstream infection treatment and the duration of concentration stability of the antibiotic solution within the lumen of the port.

  18. Hypertension with diabetes mellitus complications. (United States)

    Yamazaki, Daisuke; Hitomi, Hirofumi; Nishiyama, Akira


    Chronic diabetic complications are classified as microvascular or macrovascular and contribute to mortality and loss of quality of life. Hyperglycemia plays a critical role in the pathogenesis of microvascular complications, such as diabetic retinopathy, incipient nephropathy, and neuropathy, while atherosclerosis contributes to the pathogenesis of macrovascular complications. Diabetes mellitus and hypertension are frequently present together. Among many microvascular diabetic complications, hypertension plays a predominant role in the progression of diabetic nephropathy by glomerular hyperfiltration. Hypertension also induces atherosclerosis in diabetes. Thus, hypertension is a high-risk factor for both microvascular and macrovascular chronic diabetic complications. In this review, we summarize the current knowledge on the pathophysiological mechanisms of microvascular and macrovascular chronic diabetic complications with particular emphasis on the contribution of hypertension. We also briefly discuss various options available for the treatment of each diabetic complication.

    All physicians should be aware of the possible complications of induced abortions if only because the procedure is so commonplace. Some 250,000 induced abortions occur annually in France, amounting to 24.4 abortions per 100 live births. The rates of different complications of induced abortions before 12 weeks are .5-5/1000 for uterine perforation, .5-3.4% for hemorrhage with or without placental retention, 1% for endometritis, .3% for salpingitis .5% for continuing pregnancy, and .006 to .3/10,000 for death. A well done curettage is preferable to a poorly performed aspiration procedure. If an aspiration is done, the practitioner should bear in mind that retention of 50-200 cc of blood clots may occur if dilatation is insufficient. Symptoms appear 1-5 days after the abortion and end with expulsion of the clots or aspiration. Curettage is useless, as the clots do not represent a true retention. Uterine contractions during the aspiration can occasionally prompt a premature decision that evacuation is complete. Retention is difficult to diagnose immediately after aspiration but can be sonographically confirmed after the 8th day. Aspiration should be done after the 6th week and before the 12th week. Aspiration before the 6th week is often painful and is associated with higher rates of partial retention and of complete failure. Endouterine aspiration, regardless of technical proficiency, establishes a pathway between the vagina and the uterine cavity, which exposes the latter to the risk of trauma, endometrial lesions, and perforation. Induced abortion promotes infection by 2 mechanisms. Latent infections that were not detected in the medical history or physical examination can emerge and cause endometritis, which should be treated by ice, rest, and antibiotics. Or contamination of the passage by an infected cervical mucus can lead to salpingitis, abscess, and pelviperitonitis, or even general peritonitis. More often, these conditions develop from inadequately treated

  20. Validation of maternal cardiac output assessed by transthoracic echocardiography against pulmonary artery catheterization in severely ill pregnant women: prospective comparative study and systematic review. (United States)

    Cornette, J; Laker, S; Jeffery, B; Lombaard, H; Alberts, A; Rizopoulos, D; Roos-Hesselink, J W; Pattinson, R C


    Most severe pregnancy complications are characterized by profound hemodynamic disturbances, thus there is a need for validated hemodynamic monitoring systems for pregnant women. Pulmonary artery catheterization (PAC) using thermodilution is the clinical gold standard for the measurement of cardiac output (CO), however this reference method is rarely performed owing to its invasive nature. Transthoracic echocardiography (TTE) allows non-invasive determination of CO. We aimed to validate TTE against PAC for the determination of CO in severely ill pregnant women. This study consisted of a meta-analysis combining data from a prospective study and a systematic review. The prospective arm was conducted in Pretoria, South Africa, in 2003. Women with severe pregnancy complications requiring invasive monitoring with PAC according to contemporary guidelines were included. TTE was performed within 15 min of PAC and the investigator was blinded to the PAC measurements. Comparative measurements were extracted from similar studies retrieved from a systematic review of the literature and added to a database. Simultaneous CO measurements by TTE and PAC were compared. Agreement between methods was assessed using Bland-Altman statistics and intraclass correlation coefficients (ICC). Thirty-four comparative measurements were included in the meta-analysis. Mean CO values obtained by PAC and TTE were 7.39 L/min and 7.18 L/min, respectively. The bias was 0.21 L/min with lower and upper limits of agreement of -1.18 L/min and 1.60 L/min, percentage error was 19.1%, and ICC between the two methods was 0.94. CO measurements by TTE show excellent agreement with those obtained by PAC in pregnant women. Given its non-invasive nature and availability, TTE could be considered as a reference for the validation of other CO techniques in pregnant women. Copyright © 2016 ISUOG.

  1. Levofloxacin in the treatment of complicated urinary tract infections and acute pyelonephritis

    Directory of Open Access Journals (Sweden)

    Jessina C McGregor


    Full Text Available Jessina C McGregor, George P Allen, David T BeardenOregon State University College of Pharmacy, Portland, OR, USAAbstract: Levofloxacin is a widely used fluoroquinolone approved for the treatment of complicated urinary tract infections and acute pyelonephritis. A comprehensive review of the medical literature identified five publications evaluating levofloxacin for the treatment of either complicated urinary tract infections or acute pyelonephritis. All trials, although variable in their inclusion criteria and levofloxacin dosing strategies, reported microbiologic, clinical, and safety-related outcomes. High microbiologic eradication rates, ranging from 79.8% to 95.3%, were observed in all studies. Escherichia coli was the most commonly isolated uropathogen. Data on levofl oxacin resistance, both at baseline and after therapy, were limited. Clinical success was observed to range from 82.6% to 93% when measured after the completion of therapy. These clinical and microbiologic results were comparable to the fluoroquinolone comparators in all trials. Insufficient data are available to evaluate the outcomes in any meaningful patient subgroups, including catheterized patients, and those with other specific complicating factors. Levofloxacin was well tolerated in these studies, with headache, gastrointenstinal effects, and dizziness being the most commonly reported adverse events. The published data support the use of levofloxacin in complicated urinary tract infections and acute pyelonephritis. Further trials are necessary to evaluate levofl oxacin within specific patient sub-populations.Keywords: urinary tract infection, pyelonephritis, levofloxacin

  2. [Psychiatric complications of abortion]. (United States)

    Gurpegui, Manuel; Jurado, Dolores


    The psychiatric consequences of induced abortion continue to be the object of controversy. The reactions of women when they became aware of conception are very variable. Pregnancy, whether initially intended or unintended, may provoke stress; and miscarriage may bring about feelings of loss and grief reaction. Therefore, induced abortion, with its emotional implications (of relief, shame and guilt) not surprisingly is a stressful adverse life event. METHODOLOGICAL CONSIDERATIONS: There is agreement among researchers on the need to compare the mental health outcomes (or the psychiatric complications) with appropriate groups, including women with unintended pregnancies ending in live births and women with miscarriages. There is also agreement on the need to control for the potential confounding effects of multiple variables: demographic, contextual, personal development, previous or current traumatic experiences, and mental health prior to the obstetric event. Any psychiatric outcome is multi-factorial in origin and the impact of life events depend on how they are perceived, the psychological defence mechanisms (unconscious to a great extent) and the coping style. The fact of voluntarily aborting has an undeniable ethical dimension in which facts and values are interwoven. No research study has found that induced abortion is associated with a better mental health outcome, although the results of some studies are interpreted as or Some general population studies point out significant associations with alcohol or illegal drug dependence, mood disorders (including depression) and some anxiety disorders. Some of these associations have been confirmed, and nuanced, by longitudinal prospective studies which support causal relationships. With the available data, it is advisable to devote efforts to the mental health care of women who have had an induced abortion. Reasons of the woman's mental health by no means can be invoked, on empirical bases, for inducing an abortion.

  3. Complicity and torture. (United States)

    Shue, Henry


    One of the great merits of On Complicity and Compromise is that it wades into specific swamps where ordinary theorists fear to slog. It is persuasive that in general it can be right sometimes to be complicit in wrongdoing by others through causally contributing to the wrongdoing, but not sharing its purpose, if by being involved one can reasonably expect to lessen the extent of the wrong that would otherwise be suffered by the victims. I focus on whether the book's general thesis is applicable to torture, which depends on what torture and the torture situation are in fact like. I focus on the case to which the chapter several times refers: the innovative CIA paradigm of torture. First, to the extent that the paradigm, which is predominantly mental, or psychological, torture succeeds in its goal of producing regression to a compliant state, the physician would be unable to rely on the torture victim's expressions of preferences or interests as authentically his own. Second, since disorientation plays such a large role in the CIA's style of torture (adopted at Guantanamo by the military), the authorities would refuse to allow a stable relationship to be built up with any one doctor by any victim, making comprehension of the victim's preferences difficult. Third, even if the doctor could somehow judge what the victim's genuine interests were, the control of the situation is much too totalistic to allow the physician any action independent of what the torture regime requires.

  4. Pulmonary complications in diabetes mellitus. (United States)

    Hansen, L A; Prakash, U B; Colby, T V


    Diabetes mellitus produces serious complications in several major organ systems. The pulmonary complications, although uncommon and not well recognized, may be life-threatening. We describe a 20-year-old patient with diabetic ketoacidosis in whom pulmonary zygomycosis developed. This condition was complicated by stenosis of the left upper lobe bronchus despite successful treatment of the zygomycosis. Bronchial obstruction has become a well-recognized complication of pulmonary zygomycosis. In addition to infections caused by Zygomycetes, mycobacteria, viruses, and bacteria, the pulmonary complications described in patients with diabetes include pulmonary edema, disordered breathing during sleep, and reductions in elastic recoil of the lungs, diffusing capacity of the lungs for carbon monoxide, and bronchomotor tone. Other reported complications are respiratory alkalosis, cardiorespiratory arrest, pneumothorax, pneumomediastinum, plugging of the airways with mucus, and aspiration pneumonia attributable to diabetic gastroparesis.

  5. Complications of electrosurgery in laparoscopy

    Directory of Open Access Journals (Sweden)

    Hui-Yu Huang


    Full Text Available Electrosurgery is widely used in laparoscopic surgeries. It is essential to understand the principles of using appropriate electric currents and techniques to achieve the desired tissue effect and avoid complications. We reviewed the literature concerning the incidence of electrosurgical injuries, the mechanisms of injury, and recognition and management of electrosurgical complications. Alertness to postoperative warning signs, patient education prior to discharge, and the detection of delayed manifestations with salvage maneuvers may minimize catastrophic complications.

    Conclusions: Our study demonstrated an increased rate of placental insufficiency associated complications in women with placenta previa. This is of clinical relevance and suggests that a careful surveillance for women with placenta previa may help in minimizing maternal, fetal and neonatal complications.

  7. Assessment of DNA double-strand breaks induced by intravascular iodinated contrast media following in vitro irradiation and in vivo, during paediatric cardiac catheterization. (United States)

    Gould, Richard; McFadden, Sonyia L; Horn, Simon; Prise, Kevin M; Doyle, Philip; Hughes, Ciara M


    Paediatric cardiac catheterizations may result in the administration of substantial amounts of iodinated contrast media and ionizing radiation. The aim of this work was to investigate the effect of iodinated contrast media in combination with in vitro and in vivo X-ray radiation on lymphocyte DNA. Six concentrations of iodine (15, 17.5, 30, 35, 45, and 52.5 mg of iodine per mL blood) represented volumes of iodinated contrast media used in the clinical setting. Blood obtained from healthy volunteers was mixed with iodinated contrast media and exposed to radiation doses commonly used in paediatric cardiac catheterizations (0 mGy, 70 mGy, 140 mGy, 250 mGy and 450 mGy). Control samples contained no iodine. For in vivo experimentation, pre and post blood samples were collected from children undergoing cardiac catheterization, receiving iodine concentrations of up to 51 mg of iodine per mL blood and radiation doses of up to 400 mGy. Fluorescence microscopy was performed to assess γH2AX-foci induction, which corresponded to the number of DNA double-strand breaks. The presence of iodine in vitro resulted in significant increases of DNA double-strand breaks beyond that induced by radiation for ≥ 17.5 mg/mL iodine to blood. The in vivo effects of contrast media on children undergoing cardiac catheterization resulted in a 19% increase in DNA double-strand breaks in children receiving an average concentration of 19 mg/mL iodine to blood. A larger investigation is required to provide further information of the potential benefit of lowering the amount of iodinated contrast media received during X-ray radiation investigations.

  8. Initial experience with pre-activation of the cardiac catheterization lab and emergency room bypass for patients with ST-elevation myocardial infarction in Halifax, Nova Scotia. (United States)

    Bata, Adil; Quraishi, Ata Ur Rehman; Love, Michael; Title, Lawrence; Beydoun, Hussein; Lee, Tony; Nadeem, Najaf; Kidwai, Bakhtiar; Kells, Catherine; Curran, Helen


    To determine whether pre-activation of the cardiac catheterization lab by Emergency Health Services (EHS) with a single call system in the field was associated with reduced time to reperfusion in patients with ST-Elevation Myocardial Infarction (STEMI) undergoing primary percutaneous coronary intervention (PPCI). Consecutive STEMI patients identified by EHS and subsequently taken to the Queen Elizabeth II Health Sciences Center (QEIIHSC) for PPCI between February 1, 2011 and January 30, 2013 were examined. Patients who had pre-activation of the catheterization lab from the field (pre-act group) after the acquisition of the LifeNet® system (Physio Control, Redmond Washington) were compared to those who had usual activation (routine group) prior to the acquisition of the LifeNet® system, for outcomes including treatment timeline data and mortality. 271 patients were included in the analysis, 149 patients in the pre-act group and 122 patients in the routine group. Door-to-device (DTD) times of less than 90min were achieved more frequently in the Pre-act group (91.9% vs. 62.2%; P<0.001). DTD time was shorter in the Pre-act group (48min IQR: 38 to 63min vs. 78min IQR: 64-101min; p=0.001) as was first medical contact-to-device (FMCTD) time (91min IQR: 78 to 106min vs. 115min IQR: 90 to 139min; P<0.001). False activation of the catheterization lab was infrequent (1.3%). Implementation of catheterization lab pre-activation using the LifeNet® system was associated with more efficient reperfusion times as measured by reduced FMCTD and DTD times without excess false activation rates.

  9. Hybrid echo and x-ray image guidance for cardiac catheterization procedures by using a robotic arm: a feasibility study. (United States)

    Ma, YingLiang; Penney, Graeme P; Bos, Dennis; Frissen, Peter; Rinaldi, C Aldo; Razavi, Reza; Rhode, Kawal S


    We present a feasibility study on hybrid echocardiography (echo) and x-ray image guidance for cardiac catheterization procedures. A self-tracked, remotely operated robotic arm with haptic feedback was developed that attached to a standard x-ray table. This was used to safely manipulate a three-dimensional (3D) trans-thoracic echo probe during simultaneous x-ray fluoroscopy and echo acquisitions. By a combination of calibration and tracking of the echo and x-ray systems, it was possible to register the 3D echo images with the 2D x-ray images. Visualization of the combined data was achieved by either overlaying triangulated surfaces extracted from segmented echo data onto the x-ray images or by overlaying volume rendered 3D echo data. Furthermore, in order to overcome the limited field of view of the echo probe, it was possible to create extended field of view (EFOV) 3D echo images by co-registering multiple tracked echo data to generate larger roadmaps for procedure guidance. The registration method was validated using a cross-wire phantom and showed a 2D target registration error of 3.5 mm. The clinical feasibility of the method was demonstrated during two clinical cases for patients undergoing cardiac pacing studies. The EFOV technique was demonstrated using two healthy volunteers.

  11. Improved semen collection method for wild felids: urethral catheterization yields high sperm quality in African lions (Panthera leo). (United States)

    Lueders, I; Luther, I; Scheepers, G; van der Horst, G


    For wild and domestic felids, electroejaculation (EE) is the most common semen collection method. However, the equipment is expensive, there is a risk of urine contamination and animals usually show strong muscular contraction despite general anesthesia. Accordingly, we tested the feasibility of a different approach using urethral catheterization (UC) in seven African lions, previously described for domestic cats only. After general anesthesia with the α2-agonist medetomidine (which also stimulates semen release into the urethra) and ketamine, a transrectal ultrasound was performed to locate the prostate. A commercial dog urinary catheter (2.6 or 3.3 mm in diameter) was advanced approximately 30 cm into the urethra to allow semen collection into the lumen of the catheter by capillary forces. After retraction, sperm volumes between of 422.86 ± 296.07 μl yielded motility of 88.83 ± 13.27% (mean ± SD) with a mean sperm concentration of 1.94 × 10(9)/ml. Here we describe a simple, field friendly and effective method to attain highly concentrated semen samples with excellent motility in lions and potentially other wild felid species as an alternative to electroejaculation.

  12. The influence of patient size on dose conversion coefficients: a hybrid phantom study for adult cardiac catheterization (United States)

    Johnson, Perry; Lee, Choonsik; Johnson, Kevin; Siragusa, Daniel; Bolch, Wesley E.


    In this study, the influence of patient size on organ and effective dose conversion coefficients (DCCs) was investigated for a representative interventional fluoroscopic procedure—cardiac catheterization. The study was performed using hybrid phantoms representing an underweight, average and overweight American adult male. Reference body sizes were determined using the NHANES III database and parameterized based on standing height and total body mass. Organ and effective dose conversion coefficients were calculated for anterior-posterior, posterior-anterior, left anterior oblique and right anterior oblique projections using the Monte Carlo code MCNPX 2.5.0 with the metric dose area product being used as the normalization factor. Results show body size to have a clear influence on DCCs which increased noticeably when body size decreased. It was also shown that if patient size is neglected when choosing a DCC, the organ and effective dose will be underestimated to an underweight patient and will be overestimated to an underweight patient, with errors as large as 113% for certain projections. Results were further compared with those published for a KTMAN-2 Korean patient-specific tomographic phantom. The published DCCs aligned best with the hybrid phantom which most closely matched in overall body size. These results highlighted the need for and the advantages of phantom-patient matching, and it is recommended that hybrid phantoms be used to create a more diverse library of patient-dependent anthropomorphic phantoms for medical dose reconstruction.

  13. Reduction in Radiation Dose in a Pediatric Cardiac Catheterization Lab Using the Philips AlluraClarity X-ray System. (United States)

    Sullivan, Patrick M; Harrison, David; Badran, Sarah; Takao, Cheryl M; Ing, Frank F


    The objective of this study was to compare radiation doses and imaging quality using Philips AlluraClarity (Philips Healthcare, Best, The Netherlands) X-ray system and an older generation reference system. AlluraClarity is a new generation fluoroscopy system designed to reduce radiation without compromising image quality, but reports of its use in pediatric patients are limited. Dose area products (DAP, mGy cm(2)) and DAP/kg were compared in patients catheterized using Allura Xper and AlluraClarity systems over a year of use for each. Randomly selected studies from each system were assessed for image quality. The 430 patients imaged with Clarity were larger than the 332 imaged with Xper (median BSA: 0.74 vs. 0.64 m(2), p = 0.06), and median total fluoroscopic times (TFT) were similar (15.8 vs. 16.1 min, p = 0.37). Median DAPs were 8661 mGy cm(2) (IQR: 18,300 mGy cm(2)) and 4523 mGy cm(2) (IQR: 11,596 mGy cm(2)) with Xper and Clarity, respectively (p lab.

    Sodium bicarbonate and ascorbic acid have been proposed to prevent contrast-induced nephropathy (CIN). The present study evaluated the effect of their combined use on CIN incidence.Methods and Results:We prospectively enrolled 429 patients with chronic kidney disease (CKD: baseline estimated glomerular filtration rate ascorbic acid (n=211) groups, a total of 1,500-2,500 mL 0.9% saline was given before and after the procedure. In addition, the combination group received 20 mEq sodium bicarbonate and 3 g ascorbic acid i.v. before the procedure, followed by 2 g ascorbic acid after the procedure and a further 2 g after 12 h. There were no significant differences between the basic characteristics and contrast volume in the 2 groups. CIN occurred in 19 patients (8.7%) in the saline group, and in 6 patients (2.8%) in the combined treatment group (P=0.008). Combined sodium bicarbonate and ascorbic acid could prevent CIN following catheterization in CKD patients.

  15. Patient satisfaction in cardiology after cardiac catheterization : Effects of treatment outcome, visit characteristics, and perception of received care. (United States)

    Weidemann, R R; Schönfelder, T; Klewer, J; Kugler, J


    Patient satisfaction is a key indicator for quality of care. However, recent data on determinants of satisfaction in invasive cardiology are lacking. Hence this study was conducted to identify determinants of patient satisfaction after hospitalization for cardiac catheterization. Data were obtained from 811 randomly selected patients discharged from ten hospitals responding to a mailed post-visit questionnaire. The satisfaction dimension was measured with a validated 42-item inventory assessing demographic and visit characteristics as well as medical, organizational, and service aspects of received care. Bivariate and multivariate statistical analyses were performed to identify predictors of satisfaction. Patients were most satisfied with the kindness of medical practitioners and nurses. The lowest ratings were observed for discharge procedures and instructions. Multivariate analysis revealed five predictors of satisfaction: treatment outcome (OR, 2.14), individualized medical care (OR, 1.64), clear reply to patient's inquiries by physicians (OR, 1.63), kindness of nonmedical professionals (OR, 3.01), and room amenities (OR, 2.02). No association between demographic data and overall satisfaction was observed. Five key determinants that can be addressed by health-care providers in order to improve patient satisfaction were identified. Our findings highlight the importance of the communicational behavior of health-care professionals and the transparency of discharge management.

  16. Independence in the toilet activity in children and adolescents with myelomeningocele--managing clean intermittent catheterization in a hospital setting. (United States)

    Donlau, M; Falkmer, T


    The aim of this study was to identify and describe gross motor, fine motor, executive and time-processing obstacles for independence in children with myelomeningocele who are treated with Clean Intermittent Catheterization and to relate their opinions about their performance in the toilet activity, and their medical records, to the observed outcome. In a hospital setting, 22 children with myelomeningocele were observed using a structured information form while performing their toilet activity, and tested for time processing ability with the Ka-Tid instrument. Only five children were independent, despite the fact that 12 of 22 children were completely satisfied with their toilet activity. Neither the degree of motor impairment, nor sex or age had any significant impact on performing the toilet activity. The ability to remain focused on the toilet activity proved to have no relation to age or learning disabilities. The medical records for the children were only able to classify approximately three quarters correctly with respect to independence. The only measurement that could suggest anything in relation to a maintained focus was time processing ability. The children were unaware of their abilities and limitations. Time processing ability and observations are important factors to assess independence.

  17. Shunt Surgery, Right Heart Catheterization, and Vascular Morphometry in a Rat Model for Flow-induced Pulmonary Arterial Hypertension. (United States)

    van der Feen, Diederik E; Weij, Michel; Smit-van Oosten, Annemieke; Jorna, Lysanne M; Hagdorn, Quint A J; Bartelds, Beatrijs; Berger, Rolf M F


    In this protocol, PAH is induced by combining a 60 mg/kg monocrotalin (MCT) injection with increased pulmonary blood flow through an aorto-caval shunt (MCT+Flow). The shunt is created by inserting an 18-G needle from the abdominal aorta into the adjacent caval vein. Increased pulmonary flow has been demonstrated as an essential trigger for a severe form of PAH with distinct phases of disease progression, characterized by early medial hypertrophy followed by neointimal lesions and the progressive occlusion of the small pulmonary vessels. To measure the right heart and pulmonary hemodynamics in this model, right heart catheterization is performed by inserting a rigid cannula containing a flexible ball-tip catheter via the right jugular vein into the right ventricle. The catheter is then advanced into the main and the more distal pulmonary arteries. The histopathology of the pulmonary vasculature is assessed qualitatively, by scoring the pre- and intra-acinar vessels on the degree of muscularization and the presence of a neointima, and quantitatively, by measuring the wall thickness, the wall-lumen ratios, and the occlusion score.

  18. Implications of the Hemodynamic Optimization Approach Guided by Right Heart Catheterization in Patients with Severe Heart Failure

    Directory of Open Access Journals (Sweden)

    Luís E. Rohde


    Full Text Available OBJECTIVE: To report the hemodynamic and functional responses obtained with clinical optimization guided by hemodynamic parameters in patients with severe and refractory heart failure. METHODS: Invasive hemodynamic monitoring using right heart catheterization aimed to reach low filling pressures and peripheral resistance. Frequent adjustments of intravenous diuretics and vasodilators were performed according to the hemodynamic measurements. RESULTS: We assessed 19 patients (age = 48±12 years and ejection fraction = 21±5% with severe heart failure. The intravenous use of diuretics and vasodilators reduced by 12 mm Hg (relative reduction of 43% pulmonary artery occlusion pressure (P<0.001, with a concomitant increment of 6 mL per beat in stroke volume (relative increment of 24%, P<0.001. We observed significant associations between pulmonary artery occlusion pressure and mean pulmonary artery pressure (r=0.76; P<0.001 and central venous pressure (r=0.63; P<0.001. After clinical optimization, improvement in functional class occurred (P< 0.001, with a tendency towards improvement in ejection fraction and no impairment to renal function. CONCLUSION: Optimization guided by hemodynamic parameters in patients with refractory heart failure provides a significant improvement in the hemodynamic profile with concomitant improvement in functional class. This study emphasizes that adjustments in blood volume result in imme-diate benefits for patients with severe heart failure.

  2. Complications of the Latarjet procedure. (United States)

    Gupta, Ashish; Delaney, Ruth; Petkin, Kalojan; Lafosse, Laurent


    The Latarjet procedure is an operation performed either arthroscopically or open for recurrent anterior shoulder instability, in the setting of glenoid bone loss; with good to excellent functional results. Despite excellent clinical results, the complication rates are reported between 15 and 30 %. Intraoperative complications such as graft malpositioning, neurovascular injury, and graft fracture can all be mitigated with meticulous surgical technique and understanding of the local anatomy. Nonunion and screw breakage are intermediate-term complications that occur in less than 5 % of patients. The long-term complications such as graft osteolysis are still an unsolved problem, and future research is required to understand the etiology and best treatment option. Recurrent instability after the Latarjet procedure can be managed with iliac crest bone graft reconstruction of the anterior glenoid. Shoulder arthritis is another complication reported after the Latarjet procedure, which poses additional challenges to both the surgeon and patient.

  3. Neurological Complications of Bariatric Surgery. (United States)

    Goodman, Jerry Clay


    Obesity has attained pandemic proportions, and bariatric surgery is increasingly being employed resulting in turn to more neurological complications which must be recognized and managed. Neurological complications may result from mechanical or inflammatory mechanisms but primarily result from micro-nutritional deficiencies. Vitamin B12, thiamine, and copper constitute the most frequent deficiencies. Neurological complications may occur at reasonably predictable times after bariatric surgery and are associated with the type of surgery used. During the early post-operative period, compressive or stretch peripheral nerve injury, rhabdomyolysis, Wernicke's encephalopathy, and inflammatory polyradiculoneuropathy may occur. Late complications ensue after months to years and include combined system degeneration (vitamin B12 deficiency) and hypocupric myelopathy. Bariatric surgery patients require careful nutritional follow-up with routine monitoring of micronutrients at 6 weeks and 3, 6, and 12 months post-operatively and then annually after surgery and multivitamin supplementation for life. Sustained vigilance for common and rare neurological complications is essential.

    To assess feasibility of proper hepatic artery catheterization using a 3D model obtained from preprocedural computed tomographic angiography (CTA), fused with real-time fluoroscopy, during transarterial chemoembolization of hepatocellular carcinoma. Twenty consecutive cirrhotic patients with hepatocellular carcinoma undergoing transarterial chemoembolization were prospectively enrolled onto the study. The early arterial phase axial images of the preprocedural CTA were postprocessed on an independent workstation connected to the angiographic system (Innova 4100; GE Healthcare, Milwaukee, WI), obtaining a 3D volume rendering image (VR) that included abdominal aorta, splanchnic arteries, and first and second lumbar vertebrae. The VR image was manually registered to the real-time X-ray fluoroscopy, with the lumbar spine used as the reference. The VR image was then used as guidance to selectively catheterize the proper hepatic artery. The procedure was considered successful when performed with no need for intraarterial contrast injections or angiographic acquisitions. The procedure was successful in 19 (95 %) of 20 patients. In one patient, celiac trunk angiography was required for the presence of a significant ostial stenosis that was underestimated at computed tomography. Time for image reconstruction and registration was <10 min in all cases. The use of preprocedural CTA model with fluoroscopy enables confident and direct catheterization of the proper hepatic artery with no need for preliminary celiac trunk angiography, thus reducing radiation exposure and contrast media administration.

    Silva, Dayane R A; Mazzo, Alessandra; Jorge, Beatriz M; Souza Júnior, Valtuir D; Fumincelli, Laís; Almeida, Rodrigo G S

    The purpose of this study was to identify how training on a low-fidelity simulator impacts the confidence of caregivers and patients with neurogenic bladder who use clean intermittent urinary catheterization. Quasi-experimental study. Developed in a rehabilitation center in Brazil including patients who use clean intermittent urinary catheterization and caregivers from September to November 2013. After Ethics approval (Opinion 146/2012) during the nursing consultation, data were collected before and after training on a low-fidelity simulator. A total of 36 respondents (72.0%) patients and 14 (28.0%) caregivers participated. The self-confidence acquired after training on low-fidelity simulators was significant. In this study sample, low-fidelity simulation was demonstrated to be an effective strategy for the development of self-confidence. Low-fidelity simulation training enables patients and caregivers to increase their self-confidence when performing clean intermittent urinary catheterization and should be used as a training strategy by healthcare professionals.

  8. Hydronephrosis and renal failure following inadequate management of neuropathic bladder in a patient with spinal cord injury: Case report of a preventable complication

    Directory of Open Access Journals (Sweden)

    Vaidyanathan Subramanian


    Full Text Available Abstract Background Condom catheters are indicated in spinal cord injury patients in whom intravesical pressures during storage and voiding are safe. Unmonitored use of penile sheath drainage can lead to serious complications. Case report A 32-year old, male person, sustained complete paraplegia at T-11 level in 1985. He had been using condom catheter. Eleven years after sustaining spinal injury, intravenous urography showed no radio-opaque calculus, normal appearances of kidneys, ureters and bladder. Blood urea and Creatinine were within reference range. A year later, urodynamics revealed detrusor pressure of 100 cm water when detrusor contraction was initiated by suprapubic tapping. This patient was advised intermittent catheterisation and take anti-cholinergic drug orally; but, he wished to continue penile sheath drainage. Nine years later, this patient developed bilateral hydronephrosis and renal failure. Indwelling urethral catheter drainage was established. Five months later, ultrasound examination of urinary tract revealed normal kidneys with no evidence of hydronephrosis. Conclusion Spinal cord injury patients with high intravesical pressure should not have penile sheath drainage as these patients are at risk for developing hydronephrosis and renal failure. Intermittent catheterisation along with antimuscarinic drug should be the preferred option for managing neuropathic bladder.

  9. [A case of the complications following glycerin enema which suggested malignant hyperthermia]. (United States)

    Maeda, Emi; Mori, Yumiko; Amano, Eizo; Akamatsu, Tetsuya; Okada, Toshiki


    We experienced a case of the complications following glycerin enema which suggested malignant hyperthermia. A 73-year-old man with knee osteoarthritis was scheduled for total knee arthroplasty under general and epidural anesthesia. The patient received glycerin enema before surgery. After epidural catheterization, anesthesia was induced with thiopental, fentanyl, vecuronium and sevoflurane. The trachea was intubated and the patient was ventilated with sevoflurane-air-oxygen. Then, cola-like urine was drained and he became febrile up to 37.9 degrees C. Although there were no other symptoms suggesting malignant hyperthermia, the surgery was cancelled. We suspected not only hemolysis by the color of the serum and the blood chemistry, but also rhabdomyolysis by increased levels of serum creatine phosphokinase and myoglobin as well as urine myoglobin. He recovered uneventfully. On the third day, perirectal abscess and anal fissure were diagnosed, which were considered to be the cause of the fever. It is well-known that glycerin enema could cause hemolysis, but rabdomyolysis as a complication of glycerin enema has rarely been reported. We speculate that injection of hypertonic glycerin into the perirectal tissue could have caused rhabdomyolysis as well as hemolysis, which led to cola-like urine. The complications following glycerin enema can be incorporated to a differential diagnosis of malignant hyperthermia.

    A wide spectrum of pulmonary complications occurs in patients with pneumoconiosis. Those complications include chronic obstructive pulmonary disease, hemoptysis, pneumothorax, pleural disease, tuberculosis, autoimmune disease, anthracofibrosis, chronic interstitial pneumonia, and malignancy. Generally, imaging workup starts with plain chest radiography. However, sometimes, plain radiography has limited role in the diagnosis of pulmonary complications of pneumoconiosis because of overlapping pneumoconiotic infiltration. Computed tomography (CT), ultrasonography (US), and magnetic resonance imaging (MRI) are potentially helpful for the detection of pulmonary complications in patients with pneumoconiosis. CT, with its excellent contrast resolution, is more sensitive and specific method than plain radiograph in the evaluation of pulmonary abnormalities. CT is useful in detecting lung parenchymal abnormalities caused by infection, anthracofibrosis, and chronic interstitial pneumonia. Also, CT is valuable in distinguishing localized pneumothorax from bullae and aiding the identification of multiloculated effusions. US can be used in detection of complicated pleural effusions and guidance of the thoracentesis procedure. MRI is useful for differentiating between progressive massive fibrosis and lung cancer. Radiologists need to be familiar with the radiologic and clinical manifestations of, as well as diagnostic approaches to, complications associated with pneumoconiosis. Knowledge of the various imaging features of pulmonary complications of pneumoconiosis can enhance early diagnosis and improve the chance to cure.

  12. [Complications in brachial plexus surgery]. (United States)

    Martínez, Fernando; Pinazzo, Samantha; Moragues, Rodrigo; Suarez, Elizabeth


    Although traumatic brachial plexus injuries are relatively rare in trauma patients, their effects on the functionality of the upper limb can be very disabling. The authors' objective was to assess the complications in a series of patients operated for brachial plexus injuries. This was a retrospective evaluation of patients operated on by the authors between August 2009 and March 2013. We performed 36 surgeries on 33 patients. The incidence of complications was 27.7%. Of these, only 1 (2.7%) was considered serious and associated with the procedure (iatrogenic injury of brachial artery). There was another serious complication (hypoxia in patients with airway injury) but it was not directly related to the surgical procedure. All other complications were considered minor (wound dehiscence, hematoma, infection). There was no mortality in our series. The complications in our series are similar to those reported in the literature. Serious complications (vascular, neural) are rare and represent less than 5% in all the different series. Given the rate of surgical complications and the poor functional perspective for a brachial plexus injury without surgery, we believe that surgery should be the treatment of choice.

    Malhi, Hardip; Thompson, Rosie

    A percutaneous endoscopic gastronomy tube can be used to deliver nutrition, hydration and medicines directly into the patient's stomach. Patients will require a tube if they are unable to swallow safely, putting them at risk of aspiration of food, drink and medicines into their lungs. It is vital that nurses are aware of the complications that may arise when caring for a patient with a PEG tube. It is equally important that nurses know how to deal with these complications or from where tc seek advice. This article provides a quick troubleshooting guide to help nurses deal with complications that can arise with PEG feeding.

    Greenblatt, D J; Allen, M D


    Among 26,294 hospitalized medical patients monitored by the Boston Collaborative Drug Surveillance Program, 46% received at least one intramuscular (IM) injection. Drugs for which IM injection was the route of administration in more than 80% of all exposures included penicillin G procaine, mercurial diuretics, cyanocobalamin, streptomycin sulfate, colistimethate sodium, meperidine hydrochloride, cephaloridine, scopolamine hydrobromide, kanamycin sulfate, and iron dextran injection. Local complications of IM injection were reported in a total of only 48 patients (0.4% of all IM recipients). Local complications were most commonly associated with IM injection of cephalothin sodium. Clinically important local complications are uncommonly associated with IM injections in general. However, certain drugs, eg, cephalothin, produce injection-site complications with relatively high frequency; the clinical role of IM injection of such drugs should be reevaluated.

    Marcia Eli Girotti


    Full Text Available PURPOSE: To determine adherence rate and variables associate with patients' adherence to Clean Intermittent Self Catheterization (CISC. MATERIALS AND METHODS: Patients refereed to CISC training program between July 2006 and May 2008, were prospectively evaluated with urodynamic, 3 days bladder diary (BD and WHOQoL-bref questionnaire. After training to perform CISC, patients were evaluated at 2 weeks, monthly for 6 months and at 12 months with clinical visits and BD. Patients were considered adherent if they were performing at least 80% of the initial recommendation. RESULTS: Sixty patients (50.4 ± 19.9 years old were trained to perform CISC (21 female and 39 male. Out of them, 30 (50% had neurogenic and 30 (50% had a non-neurogenic voiding dysfunction. The adherence rate at 6 and 12 months was 61.7%, 58%, respectively. Patients < 40 years old had adherence rate of 86%. Women and neurogenic patients had higher adherence rate than their counterparts (p = 0.024 and p = 0.016, respectively. In the WHOQoL-bref, patients that adhere to the program had a significant higher score on psychological and social relationships domains. There was not difference in pre and post training WHOQoL-bref scores. Educational background, marriage status, detrusor leak point pressure, Bladder Capacity, number of leakage episodes did not play a role on the adherence rate. CONCLUSION: Patients in CISC program present a reasonable adherence after one year. Women, neurogenic voiding dysfunction and patients under 40 years old were significantly more adherents. The psychological and social relationship status seems to positively interfere on adherence. CISC did not affect patient's QoL evaluated by WHOQoL-bref.

    Kunkel, Martin; Morbach, Thomas; Kleis, Wilfried; Wagner, Wilfried


    The aim of this study was to describe demographic and clinical patterns of subjects hospitalized with complications associated with third molars (M3). The investigation was designed as a prospective cohort study composed of subjects admitted to hospital for management of M3-associated complications. The predictor variable was "clinical status of the M3" defined as (A) prophylactic M3 removal, (B) nonelective M3 removal, or (C) M3 present at the time of admission. Outcome variables were infection parameters, treatment costs, length of hospital stay, and days of disability. Postoperative complications (A and B) were compared to complications based on pericoronitis (C). Complications due to prophylactic removal (A) were compared to those arising from pericoronitis or from the removal of symptomatic teeth (B and C). From January 2003 to December 2004, 45 deep space infections, 6 mandibular fractures, 2 lingual nerve injuries, 1 parapharyngeal tooth luxation, and 1 osteomyelitis were noticed. Fifteen complications resulted from prophylactic surgery (A), 25 from nonelective removal (B), and 15 from pericoronitis (C). Direct treatment costs were 147,000 euro (A: 42,000 euro; B: 74,000 euro; C: 31,000 euro). In 10 of the 15 patients of group C, deep space involvement resulted immediately from the first episode of pericoronitis. Neither clinical markers of infection nor economic parameters showed significant differences between the groups. Within the catchment area of our institution, the majority of third molar-related hospitalizations resulted from diseased third molars or their removal.

    Full Text Available Objective: Gastrointestinal complications are responsible for substantial morbidity and mortality among renal allograft recipients. We retrospectively analyzed incidence of these complications and their impact on the patient outcome. Materials & Methods: Between 1998 to Aug 2002, 558 live related renal transplants were performed at our center. The immunosuppression used consisted mainly of cyclosporine, azathioprine and prednisolone, though varied in some patients. These patients were followed for any occurrence of significant gastrointestinal problems. Results: Out of the of 538 renal transplant recipients studied, gastro esophageal ulcerations were seen in 3% patients. Acute pancreatitis was observed in twelve (2.2% patients and four patients had acute intestinal obstruction secondary to fecal impaction. Infectious complications included acute diarrheas in 18% of patients. Three patients developed abdominal tuberculosis. Acute rejection episodes were encountered in 26% of the patients. During these episodes, 58% of patients experienced prolonged ileus. Most of these complications (66% occurred within first one-year post transplant. Three patients presenting with acute intestinal obstruction required laparotomy (two- bands, one-intussusception. There were four mortalities -two patients had severe pancreatitis, one patient had massive upper GI bleed and one succumbed due to perforation peritonitis. Conclusions: Gastrointestinal complications account for significant morbidity and mortality in renal transplant recipients. Paralytic ileus secondary to acute vascular rejection is quite common and resolves spontaneously with recovery of renal function.

  11. Corneal complications of vernal keratoconjunctivitis. (United States)

    Solomon, Abraham


    Vernal keratoconjunctivitis (VKC) is a severe bilateral chronic allergic inflammatory disease of the ocular surface. In most of the cases, the disease is limited to the tarsal conjunctiva and to the limbus. However, in the more severe cases, the cornea may be involved, leading to potentially sight threatening complications. Prompt recognition of these complications is crucial in the management of VKC, which is one of the most severe ocular allergic diseases. A vicious cycle of inflammation occurs as a result of a set of reciprocal interactions between the conjunctiva and the cornea, which results in damage to the corneal epithelium and corneal stoma, and to the formation of shield ulcers and plaques, infectious keratitis, keratoconus, scarring, and limbal stem cell deficiency. These corneal complications can cause permanent decrease or loss of vision in children suffering from VKC. Corneal complications in VKC are the result of an on-going process of uncontrolled inflammation. Proper recognition of the corneal complications in VKC is crucial, as most of these can be managed or prevented by a combination of medical and surgical measures.

  12. Pulmonary Complications due to Esophagectomy. (United States)

    Shirinzadeh, Abulfazl; Talebi, Yashar


    Esophageal carcinoma is the scourge of human beings. Pulmonary complications in patients who have undergone operation are common (20-30% of cases) and there are no suitable tools and ways to predict these complications. During a period of 10 years, from March 1998 to February 2007, 200 patients (150 male and 50 female) underwent Esophagectomy due to esophageal carcinoma in thoracic surgery ward retrospectively. Complications include the length of hospitalization, mechanical ventilation, morbidity and mortality. Patients' risk factors include age, preoperative chemo-radiotherapy, stage of the disease and preoperative spirometry condition. WE GROUPED OUR PATIENTS INTO THREE CATEGORIES: Normal (FEV1 ≥ 80% predicted), mildly impaired (FEV1 65% to 79% predicted), more severely impaired (FEV1 atelectasia in 160 patients (80%). 24 patients needed chest-tube insertion. 20 patients (10%) developed ARDS. 14 patients (7%) developed chylothorax. 20 patients (10%) of patients died during their postoperative hospital stay. 30 patients (15%) required mechanical ventilation for greater than 48 hours. We reviewed a number of preoperative clinical variables to determine whether they contributed to postoperative pulmonary complications as well as other outcomes. In general, age, impaired pulmonary function especially in those patients with FEV1 less than 65% predicted was associated with prolonged hospital length of stay (LOS). In fact pulmonary complications rate after Esophagectomy are high and there was associated mortality and morbidity.

    Diabetes is especially common in the United Arab Emirates. Its complications in patients residing in the region have yet to be fully explored. This study reports on foot problems in our diabetic patients, with emphasis on the impact of illiteracy on foot care and complications due to diabetes. Adults were randomly recruited from the Diabetes Center at Tawam-John Hopkins affiliated hospital. A questionnaire addressing foot care and problems was completed for all patients. In addition, an examination was performed by a trained nurse, an endocrinologist, and a podiatrist. Four hundred twenty-two adults with type 2 (93%) or type 1 (7%) diabetes were enrolled; 67% were females. Patients' mean age was 52 ± 13 years and duration of diabetes ≥ 1 year. Illiterate patients were 51% and were less likely to practice foot care (p=0.002), recognize foot risk factors (p=0.004), use proper footwear (p=0.010), and being physically active (pdiabetic complications, such as neuropathy (p=0.027), eye disease (p=0.032), hypertension (pfoot ulcer [OR=6.0, CI=2.1-17.2, p=0.001] were predictors of practicing foot care. Illiteracy invoked significant challenges to diabetic attentiveness and imposed increased foot complications. Physicians should realize that illiterate patients are vulnerable and require effective strategies to improve their education about the disease and reduce their diabetic complications.

    Rosińska, Justyna; Łukasik, Maria; Kozubski, Wojciech


    The diver's nervous system is extremely sensitive to high ambient pressure, which is the sum of atmospheric and hydrostatic pressure. Neurological complications associated with diving are a difficult diagnostic and therapeutic challenge. They occur in both commercial and recreational diving and are connected with increasing interest in the sport of diving. Hence it is very important to know the possible complications associated with this kind of sport. Complications of the nervous system may result from decompression sickness, pulmonary barotrauma associated with cerebral arterial air embolism (AGE), otic and sinus barotrauma, high pressure neurological syndrome (HPNS) and undesirable effect of gases used for breathing.

  16. [An ophthalmological complication of cherubism]. (United States)

    Elfahsi, A; Oujilal, A; Lahlou, M; Lazrak, A; Kzadri, M


    Cherubism is a rare familial fibro-osseous lesion usually observed in children. The diagnosis is clinical and radiological. Outcome is generally favorable, but with a risk of ophthalmologic complications, especially lower eyelid retraction, proptosis, diplopia, displacement of eyeball and loss of visual acuity. Clinicians must be aware of these complications for proper detection and specific treatment. We report a case of cherubism observed in a 10-year-old boy who presented exophthalmia with reduced visual acuity on the right due to reduction of the volume of the orbital cavity and compression of the optic nerve. Partial maxillectomy was required for decompression. Cherubism can lead to various types of ophthalmologic complications. Exophthalmos and loss of visual acuity due to compression of the optic nerve are the most common. Surgery is generally not required, but can become crucial in selected patients.

  17. Complications of cochlear implant surgery

    Kosanović Rade


    Full Text Available During the last several decades, cochlear implant has been fully recognized in treatment of severe hearing loss. Development of modern technology enabled inconceivable possibilities of technical qualities of the device as well as development of usable coding strategies, which led to extraordinary results in patient rehabilitation. Although cochlear implantation has become one of the routine operative procedures throughout the world nowadays, it gives rise to certain complications. These complications, though rare, can sometimes be very serious, even with fatal outcome. If cochlear implantation is performed by experienced and well-educated team of experts, the possibility of complications is minimal and is certainly not the argument against cochlear implantation as a method of treatment of severe hearing impairments.

  18. Laparoscopic surgery complications: postoperative peritonitis. (United States)

    Drăghici, L; Drăghici, I; Ungureanu, A; Copăescu, C; Popescu, M; Dragomirescu, C


    Complications within laparoscopic surgery, similar to classic surgery are inevitable and require immediate actions both to diminish intraoperative risks and to choose the appropriate therapeutic attitude. Peritonitis and hemorrhagic incidents are both part of the complications aspect of laparoscopic surgery. Fortunately, the incidence is limited, thus excluding the rejection of celioscopic methods. Patient's risks and benefits are to be analyzed carefully prior recommending laparoscopic surgery. This study presents a statistical analysis of peritonitis consecutive to laparoscopic surgery, experience of "Sf. Ioan" Emergency Hospital, Bucharest, and Department of Surgery (2000-2010). There were 180 (0,96%) complicated situations requiring reinterventions, from a total of 18676 laparoscopic procedures. 106 cases (0,56%) represented different grades of postoperative peritonitis. Most frequently, there were consecutive laparoscopic appendicectomia and colecistectomia. During the last decade, few severe cases of peritonitis followed laparoscopic bariatric surgical procedures. This study reflects the possibility of unfavorable evolution of postoperative peritonitis comparing with hemorrhagic incidents within laparoscopic surgery.

  19. Safety and feasibility of xenon as an adjuvant to sevoflurane anaesthesia in children undergoing interventional or diagnostic cardiac catheterization: study protocol for a randomised controlled trial. (United States)

    Devroe, Sarah; Lemiere, Jurgen; Van de Velde, Marc; Gewillig, Marc; Boshoff, Derize; Rex, Steffen


    Xenon has minimal haemodynamic side effects when compared to volatile or intravenous anaesthetics. Moreover, in in vitro and in animal experiments, xenon has been demonstrated to convey cardio- and neuroprotective effects. Neuroprotection could be advantageous in paediatric anaesthesia as there is growing concern, based on both laboratory studies and retrospective human clinical studies, that anaesthetics may trigger an injury in the developing brain, resulting in long-lasting neurodevelopmental consequences. Furthermore, xenon-mediated neuroprotection could help to prevent emergence delirium/agitation. Altogether, the beneficial haemodynamic profile combined with its putative organ-protective properties could render xenon an attractive option for anaesthesia of children undergoing cardiac catheterization. In a phase-II, mono-centre, prospective, single-blind, randomised, controlled study, we will test the hypothesis that the administration of 50% xenon as an adjuvant to general anaesthesia with sevoflurane in children undergoing elective cardiac catheterization is safe and feasible. Secondary aims include the evaluation of haemodynamic parameters during and after the procedure, emergence characteristics, and the analysis of peri-operative neuro-cognitive function. A total of 40 children ages 4 to 12 years will be recruited and randomised into two study groups, receiving either a combination of sevoflurane and xenon or sevoflurane alone. Children undergoing diagnostic or interventional cardiac catheterization are a vulnerable patient population, one particularly at risk for intra-procedural haemodynamic instability. Xenon provides remarkable haemodynamic stability and potentially has cardio- and neuroprotective properties. Unfortunately, evidence is scarce on the use of xenon in the paediatric population. Our pilot study will therefore deliver important data required for prospective future clinical trials. EudraCT: 2014-002510-23 (5 September 2014).

    Full Text Available Aim: evaluation of the incidence and the pattern of vessel complications, efficacy of the prophylactic anticoagulation therapy after kidney transplantation. Materials and methods. From March 2007 till January 2013 421 patients: 230 men (54,6% and 191 women (45,4%; mean age 43,07 ± 11,62 undergone 429 kidney transplantations in the department of pancreas and kidney transplantation of the Scientific-Research Institute of Emergency Care named after N.V. Sklifosovsky. In order to evaluate the condition and the function of the kidney transplant ultrasound investigation (daily andacquisition(weekly wereused. In cases of kidney dysfunction and assumption of vessel complications we used computerized tomography. Besides, we used daily analysis of biochemical and clinical parameters of blood and urine. Results. The most common vessel complication was the thrombosis of the microvasculature of the kidney transplant due to acute humoral and combined rejection resistant to antirejection therapy (n = 9; 2,1%; in 4 cases there was a breakage of the transplant due to the acute rejection and the urgent transplantatectomy in an effort to save the patient; thrombosis of the transplantat artery occurred in 1 case (0,23%; we observed 2 cases (0,46% of the artery stenosis and 2 cases (0,46% of venous thrombosis. Conclusion. Summary frequency of vessel complications in our clinic, including thrombosis due to rejection, was 3,49%. It fully corresponds with data obtained from the global medical community. The incidence of great vessel thrombosis was less than 1% which indicates the adequate prophylactic anticoagulation therapy. For the benefit of early diacrisis of complications Doppler sonography is needed. In case of assumption of vessel complications urgent acquisition, computerized tomography and/ or angiography are to be held. 

  1. Spontaneous left main coronary artery dissection complicated by pseudoaneurysm formation in pregnancy: role of CT coronary angiography

    Weintraub Nealw F


    Full Text Available Abstract We report a case of a 26-year-old female, who presented at 34 weeks of an uncomplicated pregnancy with an acute ST elevation anterior wall myocardial infarction. Cardiac catheterization suggested a left main coronary artery dissection with pseudoaneurysm formation. The patient's course was complicated by congestive heart failure. She was initially managed conservatively by a multidisciplinary team including heart failure specialists, obstetricians, and cardiovascular surgeons. 4 days after admission, her LMC was imaged by dual-source 64 slice Cardiac computed tomography, coronary dissection was identified extending to the lumen, and the presence of pseudoaneurysm was confirmed. She underwent subsequently a staged procedure, which included placement of an intra-aortic balloon pump, cesarean section, and coronary artery bypass grafting. This case illustrates the utility of coronary artery CT imaging to assess the complexity and stability of coronary artery dissections, thereby helping to determine the need for, and timing of revascularization procedures.

  2. Complications of the diabetic foot. (United States)

    Kim, Paul J; Steinberg, John S


    The diabetic foot is at high risk for complications because of its role in ambulation. Peripheral neuropathy and peripheral vascular disease can lead to chronic foot ulcers, which are at high risk for infection, in part attributable to areas of high pressure caused by lack of tolerance of the soft tissue and bone and joint deformity. If left untreated, infection and ischemia lead to tissue death, culminating in amputation. Treatment strategies include antibiosis, topical therapies, offloading, debridement, and surgery. A multidisciplinary team approach is necessary in the prevention and treatment of complications of the diabetic foot. Copyright © 2013 Elsevier Inc. All rights reserved.

  3. Intracraneal complications after raquis surgery. (United States)

    Sierra, J J; Malillos, M


    Intracraneal bleeding is a rare complication after raquis surgery. It is believed to occur as a drop in the intracraneal pressure after a loss of CSF secondary to an iatrogenic dural tear. We report a patient who after surgery for lumbar stenosis presented a subarachnoid haemorrhage, an intraparenchymal haematoma, and a subdural haematoma. To our knowledge, this is the first report in the literature with such complications after this type of surgery. Copyright © 2017 SECOT. Publicado por Elsevier España, S.L.U. All rights reserved.

  4. Complications from international surgery tourism. (United States)

    Melendez, Mark M; Alizadeh, Kaveh


    Medical tourism is an increasing trend, particularly in cosmetic surgery. Complications resulting from these procedures can be quite disruptive to the healthcare industry in the United States since patients often seek treatment and have no compensation recourse from insurance. Despite the increasing number of plastic surgery patients seeking procedures abroad, there have been little reported data concerning outcomes, follow-up, or complication rates. Through a survey of American Society of Plastic Surgeons (ASPS) members, the authors provide data on trends to help define the scope of the problem.

    Full Text Available Background. Sigmoid volvulus is a rare complication of pregnancy and the puerperium. Case. A 19-year-old patient, gravida 1 para 0 at 41 0/7 weeks of gestation, admitted for late-term induction of labor underwent an uncomplicated primary low transverse cesarean delivery for arrest of descent. Her postoperative period was complicated by sudden onset of abdominal pain and the ultimate diagnosis of sigmoid volvulus. Conclusion. Prompt surgical evaluation of an acute abdomen in the postpartum period is essential; delayed diagnosis and treatment can lead to significant maternal morbidity and mortality.

  6. Dengue fever complicated by hemophagocytosis (United States)

    Koshy, Maria; Mishra, Ajay Kumar; Agrawal, Bhumi; Kurup, Akhil Rajendra; Hansdak, Samuel George


    Dengue is a common acute viral febrile illness in the tropics. Although the usual presentation is that of a self-limiting illness, its complications are protean. We report a 29-year-old man who presented with an acute febrile illness and was diagnosed with dengue hemorrhagic fever. Despite appropriate supportive therapy, the patient initially improved, but subsequently had clinical deterioration. Evaluation revealed features of hemophagocytic lymphohistiocytosis. He was successfully treated with glucocorticoids and had an uneventful recovery. This case adds to the limited adult cases of virus-associated hemophagocytic syndrome in the literature and the need for prompt recognition and treatment of this rare complication. PMID:27274854

    Fernández, C; Calvete, J; García, J; Buch, E; Castells, P; Lledó, S


    Secondary FAE is a rare complication, usually located at the duodenum. The typical clinical presentation is like a digestive hemorrhage or a sepsis. We report two cases of FAE with atypical manifestations. The first case presented a lower digestive hemorrhage produced by the fistulization to the sigma. The second case appeared like an intestinal obliteration caused by the full emigration of a prosthesis to the jejunum. We wish to remark the importance of the clinical suspicion of a FAE (Key of diagnosis), and the sparing relevance of the complementary examinations and the urgency of a surgical treatment in order to avoid the high rate of morbi-mortality associated with this complication.

  8. Effect of patient's age on the profitability of inpatient cardiac catheterization: a contribution margin analysis of frequently performed procedures over a 5-year period. (United States)

    Plehn, Gunnar; Butz, Thomas; Maagh, Petra; Meissner, Axel


    Due to a continuing age shift in the German society hospital providers are concerned about the additional costs associated with the treatment of elderly patients. It is not clear if cardiac catheterization in aged patients leads to higher resource utilization and if DRG-revenues do compensate for this factor. Procedure-related and administrative data of all patients who underwent cardiac catheterization at a tertiary heart center between 2007 and 2011 were collected and analyzed. Then a profitability analysis was performed by comparing the case related variable costs with the Diagnosis-related group (DRG) per case revenues. A particular emphasis was placed on a comparative analysis of identical clusters of procedures. The most frequently performed catheterization procedure (n = 1800) was associated with significantly higher material expenditure in very old patients (178 ± 48 €) than in old (171 ± 28; p = 0.001) and young patients (172 ± 39; p = 0.046). Furthermore, radiation time and the length of hospital stay were increased in very old patients (3.5 ± 3.8 min and 6.2 ± 4.8 days) compared to old (2.7 ± 2.8 min and 4.6 ± 3.8 days; p < 0.001) and young patients (2.5 ± 2.5 min and 4.5 ± 3.9 days; p < 0.001). Due to higher DRG revenues very old patients achieved higher absolute contribution margins (2065 ± 1033 €) than old (1804 ± 1902 €; p < 0.001) and young patients (1771 ± 902 €; p < 0.001). However, the contribution margins per day were significantly smaller (440 ± 226 €) than those in old (488 ± 234 €; p = 0.001) and young patients (484 ± 206 €; p = 0.001). Catheterization of very old patients is related to lower contribution margins per day despite higher material and time expenditures. Since efforts to reduce the length of hospital stay of these patients are limited, this may result in a competitive disadvantage of hospitals which

Urinary liver-type fatty acid binding protein (L-FABP increases along with tubular hypoxia and may be a detector of systemic circulation injury. The aim of this study was to evaluate the clinical usefulness of detecting increases in urinary L-FABP levels due to administration of CM, as a prognostic biomarker for cardiovascular disease in patients without occurrence of CM-induced nephropathy undergoing cardiac catheterization procedure (CCP. Methods: Retrospective longitudinal analyses of the relationship between urinary L-FABP levels and occurrence of cardiovascular events were performed (n=29. Urinary L-FABP was measured by ELISA before CCP, and at 6, 12, 24, and 48 hours after CCP. Results: Urinary L-FABP levels were significantly higher at 12 hours (P<0.05 and 24 hours (P<0.005 after CCP compared with before CCP, only in the patients with occurrence of cardiovascular events (n=17, but not in those without cardiovascular events (n=12. The parameter with the largest area under the curve (0.816 for predicting the occurrence of cardiovascular events was the change in urinary L-FABP at 24 hours after CCP. The difference in urinary L-FABP levels (ΔL-FABP ≥11.0 µg/g creatinine between before CCP and at 24 hours after CCP was a risk factor for the occurrence of cardiovascular events (hazard ratio, 4.93; 95% confidence interval, 1.27–19.13; P=0.021. Conclusion: Measurement of urinary L-FABP before CCP and at 24 hours after CCP in patients with mild to moderate renal dysfunction may be an important indicator for risk

  11. Hemodynamic phenotyping based on exercise catheterization predicts outcome in patients with heart failure and reduced ejection fraction. (United States)

    Rieth, Andreas; Richter, Manuel Jonas; Gall, Henning; Seeger, Werner; Ghofrani, Hossein A; Mitrovic, Veselin; Hamm, Christian W


    Exercise right heart catheterization (RHC) unmasks different phenotypes based on hemodynamic response to exertion in patients with heart failure. The prognostic relevance of this approach in patients with heart failure and reduced ejection fraction (HFrEF) is uncertain. We analyzed 167 patients with HFrEF from the Kerckhoff-Klinik Heart Failure Registry who underwent supine exercise RHC with constant external workload between September 2009 and August 2014. The primary outcome was heart transplant/assist device-free survival. Hemodynamic parameters that significantly predicted outcome were identified by multivariate Cox regression analysis and assessed further by Kaplan-Meier analysis after dichotomization using cutoffs derived from receiver operating characteristic analysis. Hemodynamic phenotypes were defined based on a dichotomized flow response (exercise-induced change in cardiac output [∆CO]) combined with a dichotomized pressure response (exercise-induced change in systolic [∆sPAP] or mean pulmonary arterial pressures). ∆CO independently predicted transplant/assist device-free survival (multivariate hazard ratio [HR] 1.67; 95% confidence interval [CI], 1.09-2.58; p = 0.02). Patients with ∆CO ≥1.15 liter/min had significantly better 5-year transplant/assist device-free survival than patients with lower ∆CO (72.9% vs 22.5%; log-rank p < 0.001 [Kaplan-Meier analysis]). The hemodynamic phenotype of ∆CO <1.15 liter/min combined with ∆sPAP <17.5 mm Hg was associated with worse transplant/assist device-free survival than ∆CO ≥1.15 liter/min combined with ∆sPAP ≥17.5 mm Hg (multivariate HR 7.39; 95% CI, 2.27-24.05; p = 0.001). Exercise RHC parameters are important prognostic indices in HFrEF. Hemodynamic phenotyping using ∆CO and ∆sPAP allows enhanced risk stratification.

    de Aguiar Júnior, Wagner; Saleh, Carmen Mohamad Rida; Whitaker, Iveth Yamaguchi


    Complications in hospitalized trauma patients are major causes of morbidity and mortality. The aims of this study were to identify the in-hospital trauma patients' complications and identify the risk factors for complications in this population. A retrospective analysis was conducted in a sample from a Brazilian hospital. The sample consisted of 407 patients, 194 (47.66%) of whom had records of complications. The most common complications were infections (41.80%). The risk factors related to the complications were age, length of hospital stay, external causes, and injury severity. The complications were frequent in this sample, and the risk for complications was characterized by multiple factors.

  17. Complications of bacillus Calmette-Guerin immunotherapy in 1,278 patients with bladder cancer. (United States)

    Our series of 195 patients, plus 134 reported on in the literature and 949 reviewed by various physicians provide 1,278 patients for review of bacillus Calmette-Guerin therapy complications. Cystitis occurred in 91 per cent of the patients. Complications identified included fever more than 103F in 50 patients (3.9 per cent), granulomatous prostatitis in 17 (1.3 per cent), bacillus Calmette-Guerin pneumonitis or hepatitis in 12 (0.9 per cent), arthritis or arthralgia in 6 (0.5 per cent), hematuria requiring catheterization or transfusion in 6 (0.5 per cent), skin rash in 5 (0.4 per cent), skin abscess in 5 (0.4 per cent), ureteral obstruction in 4 (0.3 per cent), epididymo-orchitis in 2 (0.2 per cent), bladder contracture in 2 (0.2 per cent), hypotension in 1 (0.1 per cent) and cytopenia in 1 (0.1 per cent). Most of the severe irritative side effects and subsequent systemic complications can be prevented with prophylactic isoniazid given for 3 days, beginning the morning of treatment. Patients with life-threatening systemic bacillus Calmette-Guerin infection or anaphylaxis should receive 500 mg. cycloserine twice daily for 3 days in addition to combination antituberculous therapy because the rapid action of this drug may be life-saving. Direct intralesional bacillus Calmette-Guerin immunotherapy can produce sepsis and death, and should be avoided but intravesical bacillus Calmette-Guerin generally is well tolerated and has produced no complication in more than 95 per cent of the patients treated.

  18. Venous Access Ports: Indications, Implantation Technique, Follow-Up, and Complications

    Energy Technology Data Exchange (ETDEWEB)

    Walser, Eric M., E-mail: [Mayo Clinic, Department of Radiology (United States)


    The subcutaneous venous access device (SVAD or 'port') is a critical component in the care of patients with chronic disease. The modern SVAD provides reliable access for blood withdrawal and medication administration with minimal disruption to a patient's lifestyle. Because of improved materials and catheter technology, today's ports are lighter and stronger and capable of high-pressure injections of contrast for cross-sectional imaging. The majority of SVAD placement occurs in interventional radiology departments due to their ability to provide this service at lower costs, lower, complication rates, and greater volumes. Port-insertion techniques vary depending on the operator, but all consist of catheter placement in the central venous circulation followed by subcutaneous pocket creation and port attachment to the catheter with fixation and closure of the pocket. Venous access challenges occasionally occur in patients with central vein occlusions, necessitating catheterization of collateral veins or port placement in alternate locations. Complications of SVADs include those associated with the procedure as well as short- (<30 days) and long-term problems. Procedural and early complications are quite rare due to the near-universal use of real-time ultrasound guidance for vein puncture, but they can include hematoma, catheter malposition, arrhythmias, and pneumothorax. Late problems include both thrombotic complications (native venous or port-catheter thrombosis) and infections (tunnel or pocket infections or catheter-associated bloodstream infections). Most guidelines suggest that 0.3 infections/1000 catheter days is an appropriate upper threshold for the insertion of SVADs.
