    Indwelling urinary catheters are commonly used in the management of hospitalized patients. Candida can adhere to the device surface and propagate as a biofilm. These Candida biofilm communities differ from free-floating Candida, exhibiting high tolerance to antifungal therapy. The significance of catheter-associated candiduria is often unclear, and treatment may be problematic considering the biofilm drug-resistant phenotype. Here we describe a rodent model for the study of urinary catheter-associated Candida albicans biofilm infection that mimics this common process in patients. In the setting of a functioning, indwelling urinary catheter in a rat, Candida proliferated as a biofilm on the device surface. Characteristic biofilm architecture was observed, including adherent, filamentous cells embedded in an extracellular matrix. Similar to what occurs in human patients, animals with this infection developed candiduria and pyuria. Infection progressed to cystitis, and a biofilmlike covering was observed over the bladder surface. Furthermore, large numbers of C. albicans cells were dispersed into the urine from either the catheter or bladder wall biofilm over the infection period. We successfully utilized the model to test the efficacy of antifungals, analyze transcriptional patterns, and examine the phenotype of a genetic mutant. The model should be useful for future investigations involving the pathogenesis, diagnosis, therapy, prevention, and drug resistance of Candida biofilms in the urinary tract.

    A 63-year-old nonsmoker with right malignant pleural effusion derived symptomatic benefit following drainage of his effusion. Following insertion of indwelling pleural catheter (IPC), 1.3 L of blood-stained fluid was drained into underwater sealed bottle (Atrium®), but the IPC dislodged 26 h after continuous connection. We believe that the weight of the drainage bottle (including the un-emptied fluid) and the prolonged connection time contributed to this uncommon event reported in the literature. There was no recurrence when his second IPC was connected to a drainage bag which was emptied at every 500 mL, capped at 2 h each time. An anchoring stitch should also be considered when drainage devices heavier than the manufacturer bottles are used to drain IPC.

    The chronic use of urinary indwelling catheters is a common practice in the setting of long-term patient care and is associated with numerous complications. More awareness about urogenital trauma from urinary catheterization is needed, as it is as common as symptomatic urinary tract infections. There are a number of preventable measures that can be taken to decrease the risk of mechanical trauma to the urethra and glans penis caused by chronic catheterization. We present a case of a 27-year old paraplegic male needing a chronic indwelling catheter that acquired ventral penile erosion while being cared for in the ICU setting.

    Full Text Available Background: Many patients with malignant pleural effusions and ascites require repeated hospital visits for paracentesis. Materials and Methods: Patients and caregivers were taught to drain malignant effusions at home, using an indwelling catheter inserted into the pleural/ peritoneal cavity. The catheter, (ARROW 14 wire gauge with three additional side holes made to prevent blockage was inserted using the Seldenger technique for central venous cannulation and secured with a stitch. A three way stopcock was used to regulate fluid drainage. The caregiver was taught to do biweekly dressings with antiseptic ointment. Results: The catheter has been used in 200 patients over a period of five years. Two patients developed infections in the pleural cavity, which were managed with antibiotics. Two patients needed catheter change because of blockage. Other patients retained the catheter till last follow up or death. The procedure can be carried out as a day case. This article describes practical guidelines for inserting and maintaining the catheter.

    Since this is an era in which information is open concerning the benefits it brings, the field of nursing informatics earns its moment. The objective of this study was to design educational software for teaching and learning the technique of urinary indwelling catheterization and compare the acquisition of knowledge regarding the technique before and after the implementation of the educational software. This is a descriptive study using a quantitative approach. The pedagogical foundations for designing the software were the theories of Piaget and Vygotsky. The teaching-learning process was evaluated through a questionnaire consisting of 10 multiple choice questions which the 60 participants completed before and after using the software. The results showed the software made significant contributions after its application, thus being very useful in the teaching-learning process.

    AIM: To study the effect of combined indwelling catheter, hemofiltration, respiration support and traditional Chinese medicine (e.g. Dahuang) in treating abdominal compartment syndrome of fulminant acute pancreatitis.METHODS: Patients with fulminant acute pancreatitis were divided randomly into 2 groups of combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring and routine conservative measures group (group 1) and control group (group 2). Routine non-operative conservative treatments including hemofiltration, respiration support, gastrointestinal TCM ablution were also applied in control group patients. Effectiveness of the two groups was observed, and APACHE Ⅱ scores were applied for analysis.RESULTS: On the second and fifth days after treatment,APACHE Ⅱ scores of group 1 and 2 patients were significantly different. Comparison of effectiveness (abdominalgia and burbulence relief time, hospitalization time)between groups 1 and 2 showed significant difference,as well as incidence rates of cysts formation. Mortality rates of groups 1 and 2 were 10.0% and 20.7%, respectively. For patients in group 1, celiac drainage quantity and intra-abdominal pressure, and hospitalization time were positively correlated (r = 0.552, 0.748, 0.923, P <0.01) with APACHE Ⅱ scores.CONCLUSION: Combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring, short veno-venous hemofiltration (SWH), gastrointestinal TCM ablution, respiration support have preventive and treatment effects on abdominal compartment syndrome of fulminant acute pancreatitis.

    Biofilm formation in urinary indwelling catheters is one of the most critical issues that patients face. Catheters were coated with poly(catechin)-antibiotic conjugates with enhanced antimicrobial properties. Catechin was conjugated with two antibiotics, namely trimethoprim (TMP) and sulfamethoxazole (SMZ) via activation with N,N'-disuccinimidyl carbonate (DSC) and subsequent coupling to molecules containing α-amine moieties. Silicone and polyurethane catheters were functionalized in situ through laccase oxidation of catechin-antibiotic conjugates. Four antimicrobial coatings were produced, namely with poly(catechin), poly(catechin)-TMP, poly(catechin)-SMZ and poly(catechin)-TMP-SMZ. The bacterial adhesion reduction was tested on the functionalized devices using gram-negative and gram-positive strains. The most significant reduction in adhesion was observed with poly(catechin)-TMP (gram-negative -85 % and gram-positive -87 %) and with poly(catechin)-TMP-SMZ (gram-negative -85 % and gram-positive -91 %). The cytotoxicity to mammalian cells was tested by indirect contact for 5 days and revealed that all the tested coatings supported more than 90 % of viable cells. A promising approach for the increase of the indwelling catheter lifespan was developed aiming to reduce catheter-associated chronic infections.

    Hospital-acquired urinary tract infections (UTI) are mainly associated with indwelling urinary catheter use. In this chapter, the pathogenesis of hospital-acquired UTI in catheterized patients, the mechanisms by which microorganisms reach the urinary tract and are able to adhere and form biofilms, and the influence of other risk factors, such as time since catheter insertion and catheter composition, are reviewed. A wide variety of infecting microorganisms can affect patients with urinary catheters, making the choice of an adequate empirical antimicrobial course complex, particularly in cases of suspected multiresistant microorganisms. Moreover, the clinical symptoms are less characteristic in catheter infection and the diagnosis may be difficult. Treatment should be stratified according to the clinical features, which can vary from asymptomatic bacteriuria that may not require treatment, to severe septic episodes that need wide antibiotic coverage. The prevention measures for UTI in permanently catheterized patients are reviewed. Infections of the female genital tract associated with foreign bodies are mainly related to the use of intrauterine devices (IUDs). The epidemiology, microbiology profile, antimicrobial treatment, and prophylaxis of pelvic inflammatory disease related to IUD use in women are also reviewed.

    Multiple evidence-based guidelines have suggested clinicians consider external collection devices (ECD) as alternatives to indwelling catheters. Nevertheless, there is a dearth of evidence-based resources concerning their use. An expert consensus panel was convened to review the current state of the evidence, indications for ECDs as an alternative to an indwelling urinary catheter, identify knowledge gaps, and areas for future research. This article presents the results of the expert consensus panel meeting and a systematic literature review regarding ECD use in the clinical setting.

    Bacillus cereus, an opportunistic pathogen, can cause fatal infection. However, B. cereus bloodstream infections (BSIs) have not been well characterised. From 2008 to 2013, B. cereus isolates from all of the specimens and patients with B. cereus BSIs were identified. Environmental samples were collected to detect B. cereus contamination. We also characterised the clinical presentation of B. cereus BSI through analyses of risk factors for BSI and mortality. A total of 217 clinical B. cereus isolates was detected. Fifty-one patients with nosocomial infections were diagnosed as B. cereus BSI, and 37 had contaminated blood cultures. The number of B. cereus isolates and BSI patients was significantly greater from June to September than from January to April (4.9 vs. 1.5 per month and 1.2 vs. 0.2, respectively). All BSIs were nosocomial and related to central or peripheral vascular catheter. Urinary catheter [odds ratio (OR) 6.93, 95% confidence interval (CI) 2.40-20.0] was the independent risk factor associated with BSI patients when compared to patients regarded as contaminated. In-hospital mortality among BSI patients was 20% and was associated with urinary catheter (OR 34.7, 95 % CI 1.89-63.6) and higher Charlson index (OR 1.99, 95 % CI 1.26-3.12). The number of B. cereus isolates and BSI increased during summer. Inpatients with indwelling vascular or urinary catheters should be carefully monitored for potential B. cereus BSIs.

    Full Text Available Abstract Introduction Septic arthritis of the sternoclavicular joint is rare, comprising approximately 0.5% to 1% of all joint infections. Predisposing causes include immunocompromising diseases such as diabetes, HIV infection, renal failure and intravenous drug abuse. Case presentation We report a rare case of bilateral sternoclavicular joint septic arthritis in an elderly patient secondary to an indwelling right subclavian vein catheter. The insidious nature of the presentation is highlighted. We also review the literature regarding the epidemiology, investigation and methods of treatment of the condition. Conclusion SCJ infections are rare, and require a high degree of clinical suspicion. Vague symptoms of neck and shoulder pain may cloud the initial diagnosis, as was the case in our patient. Surgical intervention is often required; however, our patient avoided major intervention and settled with parenteral antibiotics and washout of the joint.

    Fernando Conrado Abrão

    Full Text Available ABSTRACT Objective: To evaluate the safety and feasibility of the use of indwelling pleural catheters (IPCs in patients with malignant pleural effusion (MPE. Methods: We prospectively collected data from patients with MPE undergoing IPC placement between January of 2014 and July of 2015. All patients submitted to IPC placement had a life expectancy > 30 days, in accordance with the MPE treatment guidelines established by the British Thoracic Society. The data collected included gender, age, body mass index, primary cancer site, duration of IPC drainage, IPC-related complications, length of hospital stay, pleural effusion recurrence, and occurrence of spontaneous pleurodesis. Results: A total of 19 patients underwent IPC placement during the study period. Median overall survival after IPC insertion was 145 days. The median follow-up among the surviving patients was 125 days (range, 53-485 days, and the median time between catheter insertion and removal was 31 days (range, 2-126 days. There were IPC-related complications in 5 patients (26.2%, and spontaneous pleurodesis was achieved in 8 (42.0%. Among those 8 patients, the IPC was removed between days 30 and 126 in 4, and spontaneous pleurodesis occurred within the first 30 days in 4. Conclusions: The use of IPCs seems to be feasible and safe in patients with MPE.

    Full Text Available Catheter-associated urinary tract infections (CAUTIs are preventable complications of hospitalization. An interdisciplinary team developed a curriculum to increase awareness of the presence of indwelling urinary catheters (IUCs in hospitalized patients, addressed practical, primarily nurse-controlled inpatient risk-reduction interventions, and promoted the use of the IUC labels (“tags”. Five thirty-minute educational sessions were cycled over three daily nursing shifts on two inpatient medical floors over a 1-year period; participants were surveyed (n=152 to elicit feedback and provide real-time insight on the learning objectives. Nurse self-reported IUC tagging was early and sustained; after the IUC tag was introduced, there was a significant increase in tagging reported by the end of the block of educational sessions (from 46.2% to 84.6%, P=0.001. Early engagement combined with a targeted educational initiative led to increased knowledge, changes in behavior, and renewed CAUTI awareness in hospitalized patients with IUCs. The processes employed in this small-scale project can be applied to broader, hospitalwide initiatives and to large-scale initiatives for healthcare interventions. As first-line providers with responsibility for the placement and daily maintenance of IUCs, nurses are ideally positioned to implement efforts addressing CAUTIs in the hospital setting.

    2005-01-01

    Full Text Available PURPOSE: To describe the technique of cervical esophagostomy with indwelling catheter for the collection of secretions and study of gastric emptying. METHODS: Esophagostomy was performed in 14 dogs, and a tube was introduced into the animals' stomachs and maintained pervious for eight weeks. The technique consisted of opening the left lateral surface of the neck for insertion of the tube, with the aid of a Mixter forceps, and the subsequent subcutaneous tunneling and exteriorization of the catheter on the dorsum of the animals. RESULTS: Successful use of the tube and its total permeability were observed in 13 animals (92.8%. In one animal, the tube was obstructed by hair, and it was replaced. Formation of a small abscess occurred in 3 animals (21.4%, followed by spontaneous drainage. No accidents occurred, and the bleeding was minimal. No deaths were registered. CONCLUSION: The described technique can be used in similar researches, as well as for animal feeding in investigations of the upper digestive tract, after esophageal resection and in major neck surgeries.

    Intrathecal baclofen (ITB) is a reversible treatment that reduces muscle tone to ameliorate spasticity and dystonia in patients with cerebral palsy (CP). The resulting decrease in energy expenditure allows patients to gain much-needed weight, albeit temporarily. Modern techniques require sufficient abdominal musculature and subcutaneous fat to permit the implantation of an indwelling pump. In patients with extremely low muscle bulk, visceral pumps may be impractical or impossible, with increased risks of dehiscence and infection. The authors describe a variation of the classical procedure in a young patient with severe cachexia. A 10-year-old boy with spastic-dystonic quadriplegic CP was admitted to the neuromedical unit. Numerous drug trials had failed, and surgical intervention was deemed necessary but was complicated by his cachectic body habitus. The authors inserted a lumbar intrathecal catheter and subcutaneously tunneled it to the anterolateral abdomen, where it was connected to a subcutaneous injection port. Baclofen was continuously infused into the subcutaneous port using a noncoring needle connected to an external pump. The needle and line were changed every 5 days to minimize the risk of sepsis. Although other techniques, such as intraventricular baclofen delivery, have been described, these are largely dependent upon sufficient musculature to support a visceral pump. A subcutaneous injection port system represents an alternative approach that reduces the risk of sepsis and may be better tolerated in cachectic patients.

    In pLT recipients, the advantages of ICVCs need to be weighed against the risk of complications. This single-center retrospective study aimed to review ICVC complications in our cohort of pLT recipients. We performed chart reviews of pLT patients having undergone transplant between 01/2000 and 03/2014 and who underwent ICVC placement either before or after LT. We identified 100 ICVC in 85 patients. Overall observation time was 90 470 catheter-days. There was no difference in catheter lifespan between those inserted pre- or post-transplant; 46% of ICVC presented a complication. Most frequent complications were MD and infection. The infection rate was 0.09 per 1000 catheter-days, and MD rate was 0.36 per 1000 catheter-days. Patients having received technical variant grafts were more at risk of complications. To the best of our knowledge, this is the first study examining ICVC complications in pLT recipients. We conclude that ICVC have a high rate of MD. Children receiving technical variants may be more at risk of complications. By removing ICVC in a select number of patients at six months post-insertion, we might avoid as much as 60% of complications.

    The conventional technique for percutaneous nephrolithotomy (PNL) ends by placing a nephrostomy tube within the access tract. However, feasibility and safety of tubeless PNL have been widely demonstrated. In this modification, a ureteral stent is usually left in place instead of the nephrostomy tube. The aim of this study is to compare the use of a postoperative indwelling double-J stent versus an overnight-externalized ureteral catheter in patients undergoing tubeless PNL. Sixty-eight patients undergoing tubeless PNL were randomized either for a postoperative double-J stent (group 1) or for an overnight-externalized ureteral catheter (group 2). Outcomes evaluated included postoperative pain, hospital stay length, incidence of hemorrhagic complications, residual lithiasis and urinary leakage. Groups were similar according to age, sex, body mass index and stone burden. There were no significant differences in terms of postoperative pain, incidence of perirenal hematomas, residual lithiasis and urinary leakage. However, patients in group 1 presented longer hospital stays (3.7 ± 1.7 vs. 1.9 ± 0.3 days; p < 0.001) and greater hematocrit drops (4.9 ± 2.2 vs. 2.1 ± 1.8 %; p < 0.001). Our results confirm that among patients undergoing tubeless PNL, both alternatives (i.e. leaving a double-J stent or an overnight-externalized ureteral catheter) are reliable and safe. However, further considerations, like the need of double-J stent removal under cystoscopy, need to be taken into account when deciding which modality to use.

    Background: In recent years, Staphylococcus epidermidis (Se) has become a major nosocomial pathogen and the most common cause of infections of implanted prostheses and other indwelling devices. This is due in part to avid biofilm formation by Se on device surfaces. However, it still remains unknown...... that how the process of Se biofilm development is associated with relapsed infection in such patients.Results: We have identified clinical Se isolates displaying enhanced biofilm dispersal and self-renewal relative to reference strain. These isolates also exhibit enhanced initial cell attachment......, extracellular DNA release, cell autolysis and thicker microcolonies during biofilm development relative to reference strain. Our genetic analyses suggest that these clinical isolates exhibit significant downregulation of RNAIII, the effector molecule of the agr quorum sensing system, and upregulation...

    : Observational prospective cohort non-controlled study. Patients receiving bladder catheter were followed from insertion to removal of the catheter, looking for the development of a positive culture. Urine cultures were done using conventional media for aerobic organisms and biochemical tests for identification. Material from a urethral meatus swab was also examined for bacteria. Statistical analysis using parametric tests for cathegorical and continuous variables, and multivariate analysis for determination of risk factors for UTI were performed. RESULTS: Incidence of UTI associated with urinary catheter was 11,0%. Univariate analysis showed 3 factos as predictors: the nature of his disease (clinical or surgical (p=0,01, stayed during hospitalization in one clinic (p=0,02and duration of catheterization (p=0,00003. In the multivariate analysis only the duration of catheterization was statistically significant.(p= 0,03. CONCLUSIONS: Incidence of UTI associated with urinary catheters in the analysed sample was 11,0%, because in the University Hospital there is a control of the alterable risk. Catheterization duration is an important risk factor for this problem. It is recommended to limit to the minimum the time of catheterization in hospitalized patients.

    Full Text Available We present an unusual complication secondary to indwelling urethral catheter placement. Routine catheter placement by the obstetrics team in a postpartum female leads to retention of the catheter and inability of its removal by both the obstetrics and urology teams. Although a retained urinary catheter is relatively common, inability to remove a catheter secondary to placement inadvertently into a ureter is extremely rare. In this paper we will discuss the options in removing a retained catheter and present our case of a retained catheter secondary to placement within the right proximal ureter.

    Decomposition of indwelling electromyographic (EMG) signals is challenging in view of the complex and often unpredictable behaviors and interactions of the action potential trains of different motor units that constitute the indwelling EMG signal. These phenomena create a myriad of problem situations that a decomposition technique needs to address to attain completeness and accuracy levels required for various scientific and clinical applications. Starting with the maximum a posteriori probability classifier adapted from the original precision decomposition system (PD I) of LeFever and De Luca (25, 26), an artificial intelligence approach has been used to develop a multiclassifier system (PD II) for addressing some of the experimentally identified problem situations. On a database of indwelling EMG signals reflecting such conditions, the fully automatic PD II system is found to achieve a decomposition accuracy of 86.0% despite the fact that its results include low-amplitude action potential trains that are not decomposable at all via systems such as PD I. Accuracy was established by comparing the decompositions of indwelling EMG signals obtained from two sensors. At the end of the automatic PD II decomposition procedure, the accuracy may be enhanced to nearly 100% via an interactive editor, a particularly significant fact for the previously indecomposable trains.

    Indwelling central venous catheters have been reported to increase the risk of superior venous cava (SVC) syndrome. This case report describes the development of acute SVC syndrome in a 28-year-old woman with end-stage renal disease implanted with a left-side hemodialysis reliable outflow graft and a right-side double lumen hemodialysis catheter via internal jugular veins. Her symptoms were not alleviated after catheter removal and systemic anticoagulation therapy. She was eventually treated with catheter-directed thrombolysis and a predischarge computer tomographic venogram on postthrombolytic procedure day 7 showed patent central veins and patient remained asymptomatic. This case demonstrates that catheter-directed thrombolysis can be safely employed to treat refractory catheter-induced acute SVC syndrome in end-stage renal disease patients.

    Background Central venous thrombosis is a serious and life-threatening complication in hemodialysis (HD) patients with an indwelling catheter. The present study aimed to investigate the prevalence and characteristics of thrombosis of the superior vena cava and auxiliary branches in Chinese HD patients with an indwelling internal jugular venous catheter and to explore its risk factors.Methods Fifty-four patients on maintenance hemodialysis (MHD) with an indwelling catheter were enrolled in this cross-sectional study. The thrombosis of the internal jugular vein, subclavical vein, brachiocephalic vein and superior vena cava was assessed by vascular ultrasound. Collected were data on age, gender, ultrafiltration volume, Kt/V, blood pressure, levels of hemoglobin, serum albumin, lipid, calcium, and phosphorus, and parathyroid hormone.Results The patients were given short- or long-term double lumen central venous catheters. Among them, 42 patients had the catheter placed into the right internal jugular vein, and 12 patients into the left internal jugular vein. Different degrees of central venous thrombosis were found in 33 patients (61.1%). The prevalence of thrombosis in the jugular vein, brachiocephalic vein, subclavical vein and superior vena cava was 61.1% (33/54), 44.4% (24/54), 16.7% (9/54) and 5.6% (3/54), respectively. Among the 33 HD patients with central venous thrombosis, the percentages for one, two, three and four affected veins were 27.3% (9/33), 45.4% (15/33), 18.2% (6/33) and 9.1% (3/33), respectively. Twelve (12/33, 36.4%) of the 33 HD patients with central venous thrombosis had clinical symptoms. Nine patients (27.3%) had edema of the upper extremity and 3 (9.1%) had new-onset symptoms of pulmonary embolism such as cough, chest distress and short breath. The incidences of diabetes mellitus and malignant tumor and levels of lipoprotein a and homocysteic acid were significantly higher in the HD patients with central venous thrombosis than in those without

    Staphylococcus epidermidis is a pathogenic organism with increasing importance in total parenteral nutrition therapy. Strict asepsis during catheter insertion prolongs the interval free from Staphylococcus epidermidis infection. Staphylococcus epidermidis colonizes the catheter after migrating from the skin. For protection, we advise a long subcutaneous tunnel for all catheters that are to be indwelling for longer than three weeks. Prompt recatheterization of a patient with Staphylococcus epidermidis sepsis can result in hematogenous seeding of the new catheter and persistence of the infection. Catheter related Staphylococcus epidermidis sepsis has subsided after catheter withdrawal, and there is no need for antibiotic therapy provided that other prosthetic materials are not placed in the vascular tree. Immunologic status of the patients is not related to the frequency or severity of Staphylococcus epidermidis infections, or both.

    The increasing use of the indwelling venous catheters and cardiovascular catheters has led to many iatrogenic complications. One of the most serious complications is catheter embolization, caused by inadvertent fracture of a fragment of catheter remaining within cardiovascular systems. In the catheter embolization, there are serious consequence such as thromboembolism, sepsis, cardiac arrhythmia and others. Fisher and Ferreyro (1978) reported a 71% incidence of serious morbidity or death following to intravascular foreign bodies in patients without removal. The authors experienced a case of retained central venous pressure monitoring catheter (CVP catheter) fragment extending from superior vena cava to hepatic segment of inferior vena cava. CVP catheter wa introduced into right subclavian venous route for hyperalimentation, because of poor general condition for operation of afferent loop syndrome following to resection of the gastric carcinoma with Billoth II operation (5 years age). On attempting removal of CVP catheter on recovery from afferent loop syndrome, a large portion of the CVP catheter was cut off in S.V.C. Percutaneous puncture of right femoral vein with Seldinger technique was done and 9F introducer sheath was indwelled. The helical basket of Dotter intravascular retriever set was advance through the sheath up to retained CVP catheter, and it was grasped. The retrieved CVP catheter fragment showed several tiny blood clots on surface. The patient was uneventfully recovered and was discharged asymptomatic on second day of the procedure.

    Full Text Available Complete eversion and transurethral prolapse of the urinary bladder is rare. We report a case of complete eversion and prolapse of bladder that occurred due to self pulling out of an indwelling Foley catheter in a 72-year-old woman. She presented with retention of urine concurrent with complete uterine procidentia. An indwelling Foley catheter was given to relieve the retention. The senile lady pulled out the catheter resulting in complete transurethral prolapse with bladder eversion. Under injection Midazolam sedation and with application of xylocain jelly the prolapsed bladder could be reduced manually back through the urethra. Definite corrective surgery was done later for the uterine prolapse.

    Brennan, Courtney; Wang, Vincent J

    2015-12-01

    The use of indwelling central venous catheters is essential for pediatric patients who require hemodialysis, parenteral nutrition, chemotherapy, or other medications. Fever is a common chief complaint in the emergency department, and fever in a patient with a central venous catheter may be related to a common cause of fever, or it may be due to a catheter-associated bloodstream infection. Catheter-associated bloodstream infections may also lead to additional complications such as sepsis, septic shock, or septic complications including suppurative thrombophlebitis, endocarditis, osteomyelitis, septic emboli, and abscesses. Early resuscitation as well as timely and appropriate antibiotic therapy have been shown to improve outcomes. This issue focuses on the approach to fever in pediatric patients with central venous catheters and the management and disposition of patients with possible catheter-associated bloodstream infections.

    2012-01-20

    Researchers may place a catheter in the ear vessel of a rabbit for a short period of time in order to collect repeated blood samples without extensive restraint of the animal. Maintaining such a catheter in a healthy rabbit can be challenging, as the animal may scratch at the ear, removing the catheter or forming a large hematoma that might impede blood sampling. The authors developed a technique for protecting the indwelling catheter by cutting a section of moleskin to the same shape as the ear and gluing it to the surface of the ear and the catheter. They applied this technique to collect multiple blood samples during 12-h periods from nine rabbits in a pharmacokinetics study. Catheters remained patent in five rabbits for 12 h, in two rabbits for 8 h, in one rabbit for 6 h and in one rabbit for 4 h. This technique allowed for collection of repeated blood samples and prevented the rabbits from interfering with the catheter while allowing them to move freely during the sampling period.

    2017-01-26

    Intermittent self-catheterisation (ISC) is a safe and effective treatment in the management of neuropathic bladder, voiding dysfunction and urinary incontinence in women. ISC has been shown to improve quality of life when used appropriately. It provides freedom for individuals who require bladder drainage as they can choose where and when to catheterise to empty the bladder. ISC requires minimum equipment, is a more discreet solution than an indwelling catheter and is relatively easy to teach in one patient visit. There are a range of different ISC catheters available on prescription. Many have been designed specifically for women and patient choice regarding product selection is an important consideration. This article describes a UK patient-satisfaction survey evaluating the female patient's perspective of learning ISC using a silicone intermittent catheter called HydroSil Go(™) that is manufactured by C.R. Bard, Inc.

    PurposeThe OptEase vena cave filter (Cordis, Piscataway, NJ) is commercially available as a retrievable or permanent filter with short recommended indwelling time, presumably due to extensive contact of the filter side struts with the inferior vena cava wall and subsequent neointimal hyperplasia leading to incorporation. Our purpose was to evaluate OptEase filter retrievals with a long indwelling time period that required unconventional retrieval techniques.Materials and MethodsWe retrospectively reviewed patients who underwent OptEase filter retrieval with long undwelling times requiring additional maneuvers for retrieval. Techniques used included rigid endobronchial forceps dissection and wire-through-loop snare. Each patient underwent postretrieval venogram to evaluate for possible complications. In addition, patients had clinical follow-up 2 weeks after the retrieval procedure.ResultsThere were three patients (2 women, 1 man; average age 64 years) who underwent OptEase filter retrieval. The mean indwelling time was 6.4 months. The indwelling filters were successfully retrieved. There were no complications. Postprocedural follow-up showed no clinical pathology.ConclusionUnconventional techniques aided in the retrieval of OptEase filters with long indwelling times.

    Full Text Available INTRODUCTION: Catheter associated Urinary Tract Infection (UTI represent the most common type of nosocomial infection and is a major health concern due to its complications and frequent recurrence. Among the nosocomial infections UTI contributes a major part. About 80% of nosocomial UTI are associated with using indwelling urinary catheters and most of them are asymptomatic. Only 5% of them develop s symptomatic UTI which leads to development of complications like bacteremia & pyelonephritis. MATERIALS AND METHODS: In th e present study a random collection of 100 urine samples from different clinical “groups ˮ like surgery, urology, AMCU, Ob stetrics & Gynecology patients with indwelling urinary catheter of different durations of catheter stay. Organisms isolated in culture, biochemical c haracterization, and antibiotic susceptibility was done. RESULTS: Among the samples tested 41/100 (41% showed culture positivity. within them surgery patients were 40.90% (18/41 , Urology accounted for, 71.42 % (20/28, in AMCU patients 20% (2/10, with more than 3 days of duration of catheter stay and in Obs & Gyn department showed 0 culture positivity. The predominant organism isolated is pseudomonas aeruginosa (34.2%, followed by Escherichia coli (22%, enterococci (12.19%, Klebsiella (12.19% and Ca ndida 19.5%. Among GNB 90% showed ESBL production, 10% ß - lactam inhibitors resistance, 90% quinolones resistant, 50% resistant to amikacin, 100% to gentamycin was o bserved. CONCLUSION: Incidence of bacteriuria in patients with indwelling urinary catheters is 41 %. Onset of bacteriuria is as early as on 3 rd day of catheterization, and gradually increases with duration of stay, technique of insertion and daily catheter care done. Pseudomonas aeruginosa and Escherichia coli are common organisms isolated. Use o f prophylactic antibiotics without doing culture, and antibiotic susceptibility testing leads to development of drug resistant organisms. So, active

    Catheter associated urinary tract infections (CAUTIs) put an unnecessary burden on patients and health care systems. The purpose of this integrative review was to examine existing evidence on preventative interventions and protocols currently implemented in intensive care units (ICUs) and the impact they have on CAUTI rates and patient outcomes. This review analysed 14 research articles obtained from electronic databases and included adult patients with urinary catheters in an ICU setting. Evidence demonstrated interventions that included criteria for catheter use, daily review of catheter necessity and discontinuation of catheter prior to day seven were successful in decreasing CAUTI rates. This review provides a scientific basis for the effectiveness of these interventions and protocols. Identification and use of interventions with the greatest positive impact on CAUTI rates are an asset to healthcare professional caring for patients with indwelling catheters and nurse clinicians developing policies.

    The people become elder in this time, everywhere. The number of patients with adenoma of the prostate is increasing. Most of them have other diseases, too. A retrospective study (2646 cases in 8 years, exactly specially analysed 469 cases from 1975/1976) was done, comparing the results of TUR and open surgery. Well known is the lower risk of TUR, the lower blood loss, the lower discomfort, the lower nursing in the postoperative period ect. There are not news in this study. But it is important, to recall some things, because it's more and more difficult, to classify an old man as an "inoperable case". Nobody knows, where he should stay. The family does not like him at home (his "dripping", his incontinence etc.) In the veterans house it's the same problem, and from the hospital he is removed, because he is an "inoperable case". The situation of this old man is very bad, because he feels there isn't a place for him and nobody likes him. Each man, also if it's the strongest one, will be broken psychically and physically after a short time. Concerning these aspects, must be enlarged the indication of removal the bladder neck obstruction per transurethral resection, more and more.

    2016-03-01

    Long-term or repeated venous access in chelonians is difficult to obtain and manage, but can be critically important for administration of medications and blood sampling in hospitalized patients. Jugular catheterization provides the most rapid and secure route for vascular access, but catheters can be difficult to place, and maintaining catheter patency may be challenging. Long multilumen polyurethane catheters provide flexibility and sampling access, and minimize difficulties, such as catheter displacement, that have been encountered with traditional over-the-needle catheters. We describe placement of 4 Fr. 13-cm polyurethane catheters in three chelonians with the use of a modified Seldinger technique. Venous access was obtained with the use of an over-the-needle catheter, which allowed placement of a 0.018-in.-diameter wire, over which the polyurethane catheter was placed. Indwelling time has ranged between 1 and 4 mo currently. All tortoises were sedated for this procedure. Polyurethane central catheters provide safe, long-term venous access that allows clinicians to perform serial blood sampling as well as intravenous administration of medications, anesthetic agents, and fluids. A jugular catheter can also allow central venous pressure measurement. Utilization of central line catheters was associated with improvements in diagnostic efficiency and therapeutic case management, with minimal risks and complications.

    Full Text Available Abstract Background Indwelling urinary catheters are the main cause of healthcare-associated urinary tract infections. It can be expected that reduction of the use of urinary catheters will lead to decreased numbers of urinary tract infection. Methods The efficacy of an intervention programme to improve adherence to recommendations to reduce the use of urethral catheters was studied in a before-after comparison in ten Dutch hospitals. The programme detected barriers and facilitators and each individual facility was supported with developing their own intervention strategy. Outcome was evaluated by the prevalence of catheters, alternatives such as diapers, numbers of urinary tract infections, the percentage of correct indications and the duration of catheterization. The costs of the implementation as well as the catheterization were evaluated. Results Of a population of 16,495 hospitalized patients 3335 patients of whom 2943 were evaluable for the study, had a urethral catheter. The prevalence of urethral catheters decreased insignificantly in neurology (OR 0.93; 95% CI 0.77 - 1.13 and internal medicine wards (OR 0.97; 95% CI 0.83 - 1.13, decreased significantly in surgical wards (OR 0.84; 95% CI 0.75 - 0.96, but increased significantly in intensive care (IC and coronary care (CC units (OR 1.48; 95% CI 1.01 - 2.17. The use of alternatives was limited and remained so after the intervention. Duration of catheterization decreased insignificantly in IC/CC units (ratio after/before 0.95; 95% CI 0.78 - 1.16 and neurology (ratio 0.97; 95% CI 0.80 - 1.18 and significantly in internal medicine (ratio 0.81; 95% CI 0.69 - 0.96 and surgery wards (ratio 0.80; 95% CI 0.71 - 0.90. The percentage of correct indications on the day of inclusion increased from 50 to 67% (p Conclusion Targeted implementation of recommendations from an existing guideline can lead to better adherence and cost savings.

    We report four patients with chronic kidney disease undergoing haemodialysis therapy, which had exhausted conventional venous access (internal jugular, subclavian) and non-conventional access (axillary, innominate) in the upper hemithorax for haemodialysis. This was primarily due to thrombosis of these veins caused by previous catheterisation. These patients did not qualify for peritoneal dialysis. Using the technique recommended by Archundia et al., 4 indwelling catheters were implanted directly in the superior vena cava in each of the patients with subsequent subcutaneous tunneling. The catheters operated correctly and are currently permeable after being used for an average of 19 months.

    Objective: Bacterial species colonize indwelling catheters as biofilm induce complications in patients care. Methods: From the biofilm matrix seven species of microbes were isolated. The predominant bacteria seen in catheters were E.coli, (27 percent) P.mirabilis (20 percent) and S.epidermis (18 percent). Results: The biomass of microbes associated with the biofilm was estimated. The mean dry weight of biomass of bacteria associated with a catheter that was used for over a month time was in the range 2.5±0.04g - 3.1 ± 0.6g. Conclusion: But it was found to colonize the microtitre plate to attain a peak growth at 84h. P.mirabilis isolated from the biofilm was able to tolerate the antibiotics tetracycline, Penicillin, Kanamycin and Gentamycin at a dose level of 20μg/ml. The study indicated that the catheter has to be replaced if biofilm formation was noticed.

    Pigs are used for long-term biomedical experiments requiring repeated injections, infusions and collections of blood samples. Thus, it is necessary for vascular catheters to be indwelling to avoid undue stress to the animals and the use of restraints. We propose a refined model of percutaneous insertion of long-term central venous catheters to minimize the surgical trauma and postoperative complications associated with catheter insertion. Different sizes of needles (18 Ga versus 21 Ga) for initial puncture of the veins were compared. In conventional pigs weighing less than 30 kg, catheter insertion may be facilitated by using a microintroducer set with a 21 Ga needle. In pigs weighing 50 kg, a standard 18 Ga needle may be preferable.

  8. Rhodococcus bacteremia in cancer patients is mostly catheter related and associated with biofilm formation.

    Directory of Open Access Journals (Sweden)

    Fadi Al Akhrass

    Full Text Available Rhodococcus is an emerging cause of opportunistic infection in immunocompromised patients, most commonly causing cavitary pneumonia. It has rarely been reported as a cause of isolated bacteremia. However, the relationship between bacteremia and central venous catheter is unknown. Between 2002 and 2010, the characteristics and outcomes of seventeen cancer patients with Rhodococcus bacteremia and indwelling central venous catheters were evaluated. Rhodococcus bacteremias were for the most part (94% central line-associated bloodstream infection (CLABSI. Most of the bacteremia isolates were Rhodococcus equi (82%. Rhodococcus isolates formed heavy microbial biofilm on the surface of polyurethane catheters, which was reduced completely or partially by antimicrobial lock solution. All CLABSI patients had successful response to catheter removal and antimicrobial therapy. Rhodococcus species should be added to the list of biofilm forming organisms in immunocompromised hosts and most of the Rhodococcus bacteremias in cancer patients are central line associated.

  9. Bacterial Biofilms and Catheters: A Key to Understanding Bacterial Strategies in Catheter-Associated Urinary Tract Infection

    Directory of Open Access Journals (Sweden)

    J Curtis Nickel

    1992-01-01

    Full Text Available Despite major technological improvements in catheter drainage systems, the indwelling Foley catheter remains the most common cause of nosocomial infection in medical practice. By approaching this common complicated urinary tract infection from the perspective of the biofilm strategy bacteria appear to use to overcome obstacles to produce bacteriuria, one appreciates a new understanding of these infections. An adherent biofilm of bacteria in their secretory products ascends the luminal and external surface of the catheter and drainage system from a contaminated drainage spigot or urethral meatus into the bladder. If the intraluminal route of bacterial ascent is delayed by strict sterile closed drainage or addition of internal modifications to the system, the extraluminal or urethral route assumes greater importance in the development of bacteriuria, but takes significantly longer. Bacterial growth within these thick coherent biofilms confers a large measure of relative resistance to antibiotics even though the individual bacterium remains sensitive, thus accounting for the failure of antibiotic therapy. With disruption of the protective mucous layer of the bladder by mechanical irritation, the bacteria colonizing the catheter can adhere to the bladder’s mucosal surface and cause infection. An appreciation of the role of bacterial biofilms in these infections should suggest future directions for research that may ultimately reduce the risk of catheter-associated infection.

    The nasogastric tube (NGT) has become a frequently used device to alleviate gastrointestinal symptoms. Nasogastric tube syndrome (NTS) is an uncommon but potentially life-threatening complication of an indwelling NGT. NTS is characterized by acute upper airway obstruction due to bilateral vocal cord paralysis. We report a case of a 76-year-old man with NTS, induced by an indwelling long intestinal tube. He was admitted to our hospital for treatment of sigmoid colon cancer. He underwent sigmoidectomy to release a bowel obstruction, and had a long intestinal tube inserted to decompress the intestinal tract. He presented acute dyspnea following prolonged intestinal intubation, and bronchoscopy showed bilateral vocal cord paralysis. The NGT was removed immediately, and tracheotomy was performed. The patient was finally discharged in a fully recovered state. NTS be considered in patients complaining of acute upper airway obstruction, not only with a NGT inserted but also with a long intestinal tube.

    Full Text Available Neonatal sepsis is an important cause of death and morbidity in newborns and is diagnosed by isolation of organism in blood culture. In several reports,reliablity of blood cultures were done from umbi lical catheters,have been demonstrated. The objective of the present study was to determine,wether an inde welling umbilical catheter, could be an alternative site for blood culture. In a prospective study over 6 months during 2006,141 paired blood cultures from 134 infant,were done simultaneously from peripheral site and umbilical catheter (mostly U. V. C,during the first four days of life. Majority of these infants were preterm and admitted to NICU for special care. these infants had indwelling umbilical line and had indication of sepsis workup. A total of 141 pairs of blood cultures were obtained from 134 infants. In 16 infants blood culture pairs were positive for one organism in both peripheral vein and umbilical site. 71. 6% of total cultures (n=11pairs were negative in boths site. A total of 22 pairs were positive in one site only,with 5 positive from peripheral vein only and the other 17 from umblical site. Two pairs were positve in boths site with two different organism. In over all 16 infant (11%of blood were considered to be contaminated. Contamination rate were 2. 4% and 9. 2% for peripheral and umbilical catheter site. Contamination rate increased after 48 hours of age in umbilical catheter. The result showed that after 2 days contamination rate for blood culture taken from catheter line increased and specifity decreased. We recommended that blood culture via umblical catheter in first 2 days in sick neonates with indwelling catheter can be a alternate site of blood culture sampelling.

    Full Text Available This prospective study was carried out over a period of 6 months in the Paediatric Intensive Care Unit (PICU of a tertiary care teaching hospital. The aim of the study was to determine the organisms causing catheter related nosocomial infections in the PICU and to study their antimicrobial susceptibility pattern. Patients with endotracheal intubation, indwelling urinary catheters and central venous catheters (CVC/venous cutdown catheters were included in the study. Colonization of the endotracheal tube, urinary catheter related infections (UCRI and colonization of the CVC/venous cutdown catheters was studied. E. coli was the commonest organism colonizing the endotracheal tube tip with maximum susceptibility to cefotaxime and amikacin. E. coli was also was the commonest organism causing UCRI with maximum susceptibility to nitrofurantoin and amikacin. Acinetobacter was the commonest organism colonizing the CVC/venous cutdown catheters with maximum susceptibility to ciprofloxacin. All these sites of catheter related infections considered together, E. coli and Klebsiella were the commonest nosocomial organisms. Both had maximum susceptibility to amikacin. Methicillin resistant Staphylococcus aureus (MRSA was isolated only from one culture. All the organisms had a poor susceptibility to cefazolin and amoxycillin. A knowledge of the resident microbial flora and their antimicrobial susceptibility pattern is necessary for formulating a rational antibiotic policy in an ICU.

    Long-term use of indwelling urinary catheters can lead to urinary tract infections and loss of catheter patency due to encrustation and blockage. Encrustation of urinary catheters is due to formation of crystalline biofilms by urease-producing microorganisms such as Proteus mirabilis. An in vitro catheter biofilm model (CBM) was used to evaluate current methods for maintaining urinary catheter patency. We compared antimicrobial-coated urinary Foley catheters, with both available catheter irrigation solutions and investigational solutions containing NVC-422 (N,N-dichloro-2,2-dimethyltaurine; a novel broad-spectrum antimicrobial). Inoculation of the CBM reactor with 10(8) colony-forming units of P. mirabilis resulted in crystalline biofilm formation in catheters by 48 h and blockage of catheters within 5 days. Silver hydrogel or nitrofurazone-coated catheters did not extend the duration of catheter patency. Catheters irrigated daily with commercially available solutions such as 0.25 % acetic acid and isotonic saline blocked at the same rate as untreated catheters. Daily irrigations of catheters with 0.2 % NVC-422 in 10 mM acetate-buffered saline pH 4 or Renacidin maintained catheter patency throughout 10-day studies, but P. mirabilis colonization of the CBM remained. In contrast, 0.2 % NVC-422 in citrate buffer (6.6 % citric acid at pH 3.8) resulted in an irrigation solution that not only maintained catheter patency for 10 days but also completely eradicated the P. mirabilis biofilm within one treatment day. These data suggest that an irrigation solution containing the rapidly bactericidal antimicrobial NVC-422 in combination with citric acid to permeabilize crystalline biofilm may significantly enhance catheter patency versus other approved irrigation solutions and antimicrobial-coated catheters.

    The benefit of the transurethral catheter to protect or measure renal function is well accepted. Urethral stricture and infection of the lower urinary tract as the complications should lead to a cautious use of catheters. A careful placement, the choice of the best material and a correct management help to avoid complications. Alternatives are discussed.

    1985-06-01

    Severe encrustation and stone formation on indwelling ureteral stents in 2 patients with a lithogenic history are reported. In both cases this complication occurred in the presence of sterile urine and treatment required pyelolithotomy in one and renal pelvic irrigation with urologic G solution in the other. Analyses of these stones revealed struvite and apatite, respectively. Dissolution of encrustations and stones via renal pelvic irrigation is suggested as a viable alternative to surgical intervention for this problem. A review of the literature shows a correlation between chronic stone formers and stent encrustation, rather than from bacteriuria alone. Long-term antibiotic suppression, more frequent followup with abdominal roentgenograms, and shorter periods of internal stenting are suggested for patients with a lithogenic history.

    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.

    2013-01-01

    Full Text Available The incidence of opportunistic infections by filamentous fungi is increasing partly due to the widespread use of central venous catheters (CVC, indwelling medical devices, and antineoplastic/immunosuppressive drugs. The case of a 13-year-old boy under treatment for acute lymphoblastic leukemia is presented. The boy was readmitted to the Pediatric Ward for intermittent fever of unknown origin. Results of blood cultures drawn from peripheral venous sites or through the CVC were compared. CVC-derived bottles (but not those from peripheral veins yielded hyaline fungi that, based on morphology, were identified as belonging to the Fusarium solani species complex. Gene amplification and direct sequencing of the fungal ITS1 rRNA region and the EF-1alpha gene confirmed the isolate as belonging to the Fusarium solani species complex. Portions of the CVC were analyzed by scanning electron microscopy. Fungi mycelia with long protruding hyphae were seen into the lumen. The firm adhesion of the fungal formation to the inner surface of the catheter was evident. In the absence of systemic infection, catheter removal and prophylactic voriconazole therapy were followed by disappearance of febrile events and recovery. Thus, indwelling catheters are prone to contamination by environmental fungi.

  20. Dedicated radial ventriculography pigtail catheter

    2013-05-15

    A new dedicated cardiac ventriculography catheter was specifically designed for radial and upper arm arterial access approach. Two catheter configurations have been developed to facilitate retrograde crossing of the aortic valve and to conform to various subclavian, ascending aortic and left ventricular anatomies. The “short” dedicated radial ventriculography catheter is suited for horizontal ascending aortas, obese body habitus, short stature and small ventricular cavities. The “long” dedicated radial ventriculography catheter is suited for vertical ascending aortas, thin body habitus, tall stature and larger ventricular cavities. This new design allows for improved performance, faster and simpler insertion in the left ventricle which can reduce procedure time, radiation exposure and propensity for radial artery spasm due to excessive catheter manipulation. Two different catheter configurations allow for optimal catheter selection in a broad range of patient anatomies. The catheter is exceptionally stable during contrast power injection and provides equivalent cavity opacification to traditional femoral ventriculography catheter designs.

    Encrustations are the most frequent complications occurring with indwelling catheters and urine drainage systems. The conditions for bacterial infections, using synthetic urine and controlled contamination by Proteus vulgaris, were standardised by using an in vitro model. Crystal deposits on catheters were analysed by infra-red spectroscopy and scanning electron microscopy. The main components of deposits in all investigations were struvite (MgNH4PO4.6H2O) 60-70% and carbonate apatite (Ca10(PO4,CO3)6 (OH,CO3)2) 30-40%. Investigations as to the quality and quantity of encrustations confirmed the analysis. Irrigation treatment was carried out with physiological saline solution and citric acid solution (Suby G) to study and quantify the dissolution of crystal deposits. Regular irrigation with citric solution resulted in a 70% dissolution of encrustations and ensured free flow as ascertained by measuring flow rates.

  3. Low Cardiac Output Secondary to a Malpositioned Umbilical Venous Catheter: Value of Targeted Neonatal Echocardiography

    2014-05-01

    Full Text Available Systemic hypotension is common in very low birthweight preterm infants but the nature of the precipitating cause may be unclear. Targeted neonatal echocardiography (TnEcho is being increasingly used to support hemodynamic decisions in the neonatal intensive care unit (NICU, including identifying impairments in the transitional circulation of preterm infants, providing timely re-evaluation after institution of therapies and evaluating the placement of indwelling catheters. We present a case of a preterm infant with systemic hypotension and low cardiac output secondary to a large transatrial shunt induced by a malpositioned umbilical venous catheter. Repositioning of the line led to resolution of the hemodynamic disturbance and clinical instability, highlighting the utility of TnEcho in the NICU.

    Pei Wang

    Full Text Available Right internal jugular vein (IJV is a preferred access route for tunneled (cuffed dialysis catheters (TDCs, and both right external jugular vein (EJV and left IJV are alternative routes for patients in case the right IJV isn't available for TDC placement. This retrospective study aimed to determine if a disparity exists between the two alternative routes in hemodialysis patients in terms of outcomes of TDCs.49 hemodialysis patients who required TDCs through right EJV (n = 21 or left IJV (n = 28 as long-term vascular access were included in this study. The primary end point was cumulative catheter patency. Secondary end points include primary catheter patency, proportion of patients that never required urokinase and incidence of catheter-related bloodstream infections (CRBSI.A total of 20,870 catheter-days were evaluated and the median was 384 (interquartile range, 262-605 catheter-days. Fewer catheters were removed in the right EJV group than in the left IJV group (P = 0.007. Mean cumulative catheter patency was higher in the right EJV group compared with the left IJV group (P = 0.031. There was no significant difference between the two groups in the incidence of CRBSI, primary catheter patency or proportion of patients that never required urokinase use. Total indwell time of antecedent catheters was identified as an independent risk factor for cumulative catheter patency by Cox regression hazards test with an HR of 2.212 (95% CI, 1.363-3.588; p = 0.001.Right EJV might be superior to left IJV as an alternative insertion route for TDC placement in hemodialysis patients whose right IJVs are unavailable.

    AIM: To report our experience with computed tomography (CT)-guided percutaneous catheter drainage (PCD) of iliopsoas abscesses. MATERIALS AND METHODS: Twenty-two iliopsoas abscesses in 21 patients (11 women, 10 men) aged between 18 and 66 years (mean 36 years) were treated with PCD. Abdominal CT demonstrated the iliopsoas abscesses, which were definitively determined by Gram staining and aspirate cultures. Twenty of the 22 iliopsoas abscesses were primary and two were secondary. All PCD procedures were performed under local anaesthesia using a single-step trocar technique (n=19) or Seldinger technique (n=3). RESULTS: PCD was an effective treatment in 21 out of the 22 iliopsoas abscesses. Recurrence was seen in three abscesses as minimal residual collections. Two of them resolved spontaneously with anti-tuberculous regimen. One required percutaneous needle aspiration. The procedure failed in a diabetic patient with a secondary abscess, who died due to sepsis. The length of time that catheters remained in place ranged from 21 to 75 days (mean 59.7 days). Complications included catheter dislocation in four abscesses, which required removal of dislocated catheters and indwelling new ones. CONCLUSION: CT-guided PCD is a safe and effective front-line treatment of iliopsoas abscesses. Surgery should be reserved for failure of PCD and presence of contraindications to PCD.

    Phlebitis and cellulitis are commonly encountered problems in oncology patients receiving chemotherapy through peripherally inserted intravenous catheters. Use of central venous access devices (CVAD) is desirable. We have seen a steady increase in the use of CVADs in our oncology service with frequent use of indwelling ports, particularly during the last 2 years. In this study we have attempted to elucidate advantages of CVAD and compared them to peripheral catheters. This is a retrospective study with chart review of all oncology patients admitted in our oncology service at the Aga Khan University Hospital from March 2003 to March 2005. A survey was also conducted from a randomly selected sample of parents of children with cancer to elicit parental views regarding their choice of a particular catheter. Catheter-related infections were quite common (over 50%) in patients with peripheral lines, resulting in increased costs and prolonged hospitalization. Externalized CVADs were found difficult to care for, carried a risk of being accidentally pulled out or punctured, and were deemed undesirable for older female patients for cosmetic reasons. We found that the internalized CVADs (portacath) were superior to the externalized or peripheral lines and resulted in better patient and family satisfaction. Use of peripheral lines must be gradually phased out of pediatric oncology practice in Pakistan. Indwelling CVADs have become the standard of care internationally and should be considered for most patients in developing countries whenever resources are available.

    The objective of this study is to determine the catheter-related bloodstream infection (CRBSI) rate in a severely burned patient population, many of whom required prolonged use of central venous catheters (CVCs). Between January 2008 and June 2012, 151 patients underwent placement of 455 five-lumen minocycline/rifampin-impregnated CVCs. CRBSI was defined as at least one blood culture (>100,000 colonies) and one simultaneous roll-plate CVC tip culture (>15 colony forming units) positive for the same organism. Most patients had accidental burns (81.5%) with a mean TBSA of 50%. A mean of three catheters were inserted per patient (range, 1-25). CVCs were inserted in the femoral vein (91.2%), subclavian vein (5.3%), and internal jugular vein (3.3%). Mean overall catheter indwell time was 8 days (range, 0-39 days). The overall rate of CRBSI per 1000 catheter days was 11.2; patients with a TBSA >60% experienced significantly higher rates of CRBSI than patients with a TBSA ≤60% (16.2 vs 7.3, P = .01). CVCs placed through burned skin were four times more likely to be associated with CRBSI than CVCs placed through intact skin. The most common infectious organism was Acinetobacter baumannii. Deep venous thrombosis developed in eleven patients (7%). The overall rate of CRBSI was 11.2, consistent with published rates of CRBSI in burn patients. Thus, femoral placement of 5-lumen CVCs did not result in increased CRBSI rates. These data support the safety of femoral CVC placement in burn patients, contrary to the Centers for Disease Control recommendation to avoid femoral CVC insertion.

    Indwelling central venous catheters (CVCs) are used in the management of hematologic patients. However, insertion and maintenance of CVCs are susceptible to complications. Study design and methods data concerning 388 consecutive catheterisations, performed in oncohematologic patients between April 2003 and December 2004, were prospectively collected. At insertion thrombocytopenia was present in 109 cases (28.1%) and neutropenia in 67 (17.3%). Hemorrhage after CVC insertion occurred in five thrombocytopenic patients (1.3%). The median duration of catheterisation was 18.8 days (range 1-89), longer in the 7-French CVCs utilised in leukemic patients (24.3 days) and shorter in 12-French CVCs (11 days), used for PBSC harvesting. Deep venous thrombosis was diagnosed in 13 cases (3.3%). Ninety-two catheterisations (12.6/1000 days-catheter) were complicated by infections: 19 local infections (4.8%) and 73 (18.8%) bacteraemias of which 45 (11.6%) were catheter-related, mainly due to Gram positive germs (32/45, 71.1%). The frequency of catheter-related bacteraemia was 7.2 events/1000 days-catheter. Thirteen CVCs were removed due to thrombosis, 15 due to infections, 20 due to malfunction, the remaining 333 at patients discharge. At univariate analysis high-dose chemotherapy (p = 0.013), 7-Fr lumen (p = 0.023), acute myeloid leukemia (AML) (p = 0.001), duration of neutropenia >10 days and length of catheterisation were significantly correlated to infection. Multivariate analysis confirmed the duration of catheterisation, AML and high-dose chemotherapy as risk factors. Even though hematological in-patients are at increased risk for bleeding and infections, non-tunnelled CVCs offer a safe venous access also in patients affected by severe thrombocytopenia and prolonged neutropenia.

    Full Text Available A polyurethane intraurethral catheter (IUC was used in 27 patients with benign prostatic hypertrophy who were unfit for surgery, or were awaiting surgery. All of them had previously had a periurethral catheter inserted. The IUC was inserted with a cystoscope under fluoroscopic control. Spontaneous voiding through the IUC resumed in 25 patients (93% in the immediate postprocedure period. At the end of 6 months follow-up, the peak flow rates and the residual volumes estimated in 22 patients were satisfactory. Immediate complications included incontinence due to distal displacement in 2 patients and hematuria in one patient; long-term complications included mild encrustation of the IUC in 2 patients and calculus formation on the IUC in 1 patient. None of the patients had clinically significant urinary tract infection. The presence of the IUC did not compromise the subsequent transurethral resection of the prostate gland. We recommend the use of an IUC for up to 6 months in patients with urinary retention who are awaiting surgery or are unfit for surgery as an alternative to an indwelling urethral catheter.

    We present a 38-year-old lady with a prolonged indwelling ureteral stent that had been placed for pain relief after development of Steinstrasse following extracorporeal lithotripsy for a 2.5-cm left renal calculus. The patient developed candidal urosepsis within 6 hours after ureteroscopy and percutaneous nephrolithotomy (PCNL) for the removal of residual fragments. She subsequently recovered on systemic antifungal therapy in the form of intravenous amphotericin B and achieved complete stone clearance after repeat ureteroscopy and PCNL. Fungal urosepsis is known to complicate the postoperative course in chronically debilitated patients with poor nutritional status or those with diabetes or other significant comorbities. To our knowledge, this is the first reported case of a patient with no significant comorbities developing fungal urosepsis after endoscopic intervention for a long-term indwelling ureteral stent.

    A hydrodynamic model is proposed to describe one of the most critical problems in intensive medical care units: the formation of biofilms inside central venous catheters. The incorporation of approximate solutions for the flow-limited diffusion equation leads to the conclusion that biofilms grow on the internal catheter wall due to the counter-stream diffusion of blood through a very thin layer close to the wall. This biological deposition is the first necessary step for the subsequent bacteria colonization.

    Cardiac catheterization with ultrasound (US) imaging catheters provides real time US imaging from within the heart, but manually navigating a four degree of freedom (DOF) imaging catheter is difficult and requires extensive training. Existing work has demonstrated robotic catheter steering in constrained bench top environments. Closed-loop control in an unconstrained setting, such as patient vasculature, remains a significant challenge due to friction, backlash, and physiological disturbances. In this paper we present a new method for closed-loop control of the catheter tip that can accurately and robustly steer 4-DOF cardiac catheters and other flexible manipulators despite these effects. The performance of the system is demonstrated in a vasculature phantom and an in vivo porcine animal model. During bench top studies the robotic system converged to the desired US imager pose with sub-millimeter and sub-degree-level accuracy. During animal trials the system achieved 2.0 mm and 0.65° accuracy. Accurate and robust robotic navigation of flexible manipulators will enable enhanced visualization and treatment during procedures.

  2. The relationship between the antimicrobial effect of catheter coatings containing silver nanoparticles and the coagulation of contacting blood.

    It is well known that surface coatings for medical devices can be made antimicrobial through introduction of silver nanoparticles. By virtue of their extremely large surface-to-volume ratio, the silver particles serve as a depot for sustained release of silver ions, despite the fact that silver is not readily oxidized. Antimicrobial coatings are especially important in connection with indwelling catheters with a high risk of bacterial line infections, such as central venous catheters (CVCs). This study specifically addressed the question what the impact of silver nanoparticles (exposed at the coating's surface) and/or the release of silver ions would be on coagulation of contacting blood. Studies, performed in vitro with fresh platelet-rich blood plasma (PRP) from 5 different healthy volunteer donors, clearly pointed out that: (i) the presence of silver nanoparticles correlates with accelerated thrombin formation upon contact of the coating with PRP; (ii) platelet activation is stronger as a result from the contact with silver nanoparticle-containing coatings as compared to other coatings which are devoid of silver. A series of titration experiments, in which the potential effect of silver ions is mimicked, revealed that the observed activation of blood platelets can be best explained through a collision mechanism. The results suggest that platelets that collide with silver, exposed at the surface, become activated without adhering to the surface. These new results point, rather unexpectedly, at a double effect of the silver nanoparticles in the coating: a strong antimicrobial effect occurs simultaneously with acceleration of the coagulation of contacting blood. This new information is, evidently, most relevant for the development of improved surface coatings for indwelling catheters (such as CVCs) which should combine antimicrobial features and close-to-zero thrombogenicity.

METHODS Different means of targeted surveillance and nursing interventions were carried out, including implementing strict aseptic techniques, shortening the time of catheter indwelling, selecting the appropriate site and catheter, choosing and replacing dressing, nursing of the catheter connector and input device, and preventing thrombopoiesis. The incidence of central venous catheter-related infections in ICU before and after implementing the nursing interventions was statistical analyzed. RESULTS The total indwelling catheter-days were significantly increased after the implementation of nursing interventions(P<0. 05). the incidence of central venous catheter-related infections decreased to 2. 28/thousand catheter-days in 2010, which was 7. 67/ thousand catheter-days in 2008 and 5. 69/thousand catheter-days in 2009 (P<0. 05). CONCLUSION Implementation of the nursing interventions significantly reduces the incidence rate of central venous catheter-related infections.

    Full Text Available The bacteriological profile of epidural catheters was studied in 88 patients. Skin swabs before catheterizationand before removal of catheter with their controls were cultured in TSB Medium. The catheter hub, theportion at the skin puncture site and at the tip were cultured in TSB Medium. The 1cm of the catheter bitjust before the tip was cultured in TGB medium for anaerobes.Both, the skin controls swabs and theanaerobic culture, were negative. From the remaining, 56 positive cultures were obtained. Staphylococcusepidermidis was the predominant organism in 52% followed by staphylococcus aureus 25%. The remaining23% was shared by Acinetobacter, Pseudomonas, Klebsiella, and E. coli. All the positive cultures fromskin prior to epidural catheterization had turned sterile by 48 hours, indicating continued bactericidal actionof the disinfectant. The likely source of positive skin cultures at 48 hours is hair follicles.The catheter tipculture was positive in 9 specimen, none of which resulted in the formation of epidural abscess. In 3 casesthe cultures of skin puncture site and the tip were identical indicating tracking-in of the organisms.

    We report a flexible shaft-based mechanical scanning photoacoustic endoscopy (PAE) system that can be potentially used for imaging the human gastrointestinal tract via the instrument channel of a clinical video endoscope. The development of such a catheter endoscope has been an important challenge to realize the technique's benefits in clinical settings. We successfully implemented a prototype PAE system that has a 3.2-mm diameter and 2.5-m long catheter section. As the instrument's flexible shaft and scanning tip are fully encapsulated in a plastic catheter, it easily fits within the 3.7-mm diameter instrument channel of a clinical video endoscope. Here, we demonstrate the intra-instrument channel workability and in vivo animal imaging capability of the PAE system.

    We aimed to compare the effectiveness of various catheters for prevention of catheter-related infection and to evaluate whether specific catheters are superior to others for reducing catheter-related infections. We identified randomised, controlled trials that compared different types of central venous catheter (CVC), evaluating catheter-related infections in a systematic search of articles published from January 1996 to November 2009 via Medline, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials. Network meta-analysis with a mixed treatment comparison method using Bayesian Markov Chain Monte Carlo simulation was used to combine direct within-trial, between-treatment comparisons with indirect trial evidence. Forty-eight clinical trials (12 828 CVCs) investigating 10 intervention catheters contributed to the analyses. For prevention of CVC colonisation, adjusted silver iontophoretic catheters (odds ratio: 0.58; 95% confidence interval: 0.33-0.95), chlorhexidine and silver sulfadiazine catheters (0.49; 0.36-0.64), chlorhexidine and silver sulfadiazine blue plus catheters (0.37; 0.17-0.69), minocycline-rifampicin catheters (0.28; 0.17-0.43) and miconazole-rifampicin catheters (0.11; 0.02-0.33) were associated with a significantly lower rate of catheter colonisation compared with standard catheters. For prevention of CRBSI, adjusted heparin-bonded catheters (0.20; 0.06-0.44) and minocycline-rifampicin catheters (0.18; 0.08-0.34) were associated with a significantly lower rate of CRBSI with standard catheters. Rifampicin-based impregnated catheters seem to be better for prevention of catheter-related infection compared with the other catheters.

    Implantation of neural progenitor cells into the central nervous system has attracted strong interest for treatment of a variety of pathologies. For example, the replacement of dopamine-producing (DA) neural cells in the brain appears promising for the treatment of patients affected by Parkinson's disease. Previous studies of cell-replacement strategies have shown that less than 90% of implanted cells survive longer than 24 - 48 hours following the implantation procedure. However, it is unknown if these cells were viable upon delivery, or if they were affected by other factors such as brain pathology or an immune response. An instrumented cell-delivery catheter has been developed to assist in answering these questions by facilitating quantification and monitoring of the viability of the cells delivered. The catheter uses a fiber optic probe to perform flourescence-based cytometric measurments on cells exiting the port at the catheter tip. The current implementation of this design is on a 3.2 mm diameter catheter with 245 micrometer diameter optical fibers. Results of fluorescence testing data are presented and show that the device can characterize the quantity of cell densities ranging from 60,000 cells/ml to 600,000 cells/ml with a coefficient of determination of 0.93.

    Biofilm-associated infections are a major complication of implanted and indwelling medical devices like urological and venous catheters. They commonly persist even in the presence of an oral or intravenous antibiotic regimen, often resulting in chronic illness. We have developed a new approach to inhibiting biofilm growth on synthetic materials through controlled release of salicylic acid from a polymeric coating. Herein we report the synthesis and testing of a ultraviolet-cured polyurethane acrylate polymer composed, in part, of salicyl acrylate, which hydrolyzes upon exposure to aqueous conditions, releasing salicylic acid while leaving the polymer backbone intact. The salicylic acid release rate was tuned by adjusting the polymer composition. Anti-biofilm performance of the coatings was assessed under several biofilm forming conditions using a novel combination of the MBEC Assay™ biofilm multi-peg growth system and bioluminescence monitoring for live cell quantification. Films of the salicylic acid-releasing polymers were found to inhibit biofilm formation, as shown by bioluminescent and GFP reporter strains of Pseudomonas aeruginosa and Escherichia coli. Urinary catheters coated on their inner lumens with the salicylic acid-releasing polymer significantly reduced biofilm formation by E. coli for up to 5 days under conditions that simulated physiological urine flow.

    Central venous access devices (CVAD) are increasingly being used for optimal delivery of clotting factor concentrates in patients with haemophilia with poor peripheral venous access. The utility of CVAD is particularly well recognized in young patients starting factor prophylaxis and in patients with inhibitors undergoing immune tolerance induction (ITI). A catheter-related infection (CRI) remains the most common complication of CVAD in haemophilia patients and is the most frequent indication for its removal. Additionally, in some patients the infection results in significant morbidity and mortality and also contributes to failure of the ITI regimen. Ethanol-lock therapy (ELT) is a treatment modality that has been used to treat CRI in patients with indwelling catheters for home parenteral nutrition and chemotherapy. The aim of this study was to report the success in treating CRI in haemophilia patients using ELT. Three severe haemophilia A patients undergoing ITI regimen who developed CVAD infections resistant to conventional management with antibiotics were treated by ELT according to the institutional technique. All three patients responded well to ELT with clearance of the CVAD infection. There were no adverse side effects. To our knowledge, this is the first report of ELT in patients with haemophilia. The role of ELT needs to be investigated in larger studies for treatment of CRI in patients with bleeding disorders.

    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.

    Full Text Available CONTEXT AND OBJECTIVE: Long-term totally implantable catheters (e.g. Port-a-Cath® are frequently used for long-term venous access in children with cancer. The use of this type of catheter is associated with complications such as infection, extrusion, extravasation and thrombosis. Embolism of catheter fragments is a rare complication, but has potential for morbidity. The aim here was to report on two cases in which embolism of fragments of a long-term totally implantable catheter occurred. DESIGN AND SETTING: Case series study at Hospital do Servidor Público Estadual, São Paulo. METHODS: Retrospective review of catheter embolism in oncological pediatric patients with long-term totally implantable catheters. RESULTS: The first patient was a 3-year-old girl diagnosed with stage IV Wilms' tumor. Treatment was started with the introduction of a totally implantable catheter through the subclavian vein. At the time of removal, it was realized that the catheter had fractured inside the heart. An endovascular procedure was necessary to remove the fragment. The second case was a boy diagnosed with stage II Wilms' tumor at the age of two years. At the time of removal, it was noticed that the catheter had disconnected from the reservoir and an endovascular procedure was also necessary to remove the embolized catheter. CONCLUSION: Embolism of fragments of totally implantable catheters is a rare complication that needs to be recognized even in asymptomatic patients.

    Catheter-associated urinary tract infections (CAUTIs) are the most common hospital-acquired infections. The purpose of this quality improvement (QI) project was to successfully implement a nurse-led evidence-based practice change designed to reduce CAUTIs in a cardiac intensive care and step-down unit. The QI project was implemented using a convenience sample of patients admitted to the cardiac intensive care and step-down unit.Evaluation data were collected 3 months preimplementation and 9 months postimplementation. We used Wick's Check-Plan-Do-Check-Act model of continuous QI to guide the project. A statistically significant change in the number of CAUTIs (P = .009) and CAUTI occurrences (P = .005) was observed following the intervention. The number of indwelling catheter days and indwelling catheter utilization did not significantly differ following implementation of the intervention. Nurse compliance with the intervention was computed for each month; the average compliance rate was 91%. Findings from this project indicate that a nurse-led evidence-based practice project exerted a positive influence on CAUTI occurrences.

    Sarcoma developing in association with a metallic orthopedic procedure is an uncommon but well-recognized complication in mammals. We report on a synovial sarcoma that developed at the site of an intramedullary pin after surgery to treat a bone fracture. A 17-year-old female peach-faced lovebird (Agapornis roseicollis) developed a spherical mass on the distal right dorsal wing at a site that was previously fractured and surgically repaired with an indwelling intramedullary pin. The right wing was amputated at the scapulohumeral joint. One year later, the bird died. Postmortem examination revealed metastases in the right lung, left thoracic wall, and proventricular serosa. Histologically, the tumor had a characteristic biphasic pattern. The tumor was immunohistologically and ultrastructurally identified as a synovial sarcoma. This is the first report of a suspected fracture-associated sarcoma in a bird.

    Robotic catheters have the potential to revolutionize cardiac surgery by enabling minimally invasive structural repairs within the beating heart. This paper presents an actuated catheter system that compensates for the fast motion of cardiac tissue using 3D ultrasound image guidance. We describe the design and operation of the mechanical drive system and catheter module and analyze the catheter performance limitations of friction and backlash in detail. To mitigate these limitations, we propose and evaluate mechanical and control system compensation methods, including inverse and model-based backlash compensation, to improve the system performance. Finally, in vivo results are presented that demonstrate that the catheter can track the cardiac tissue motion with less than 1 mm RMS error. The ultimate goal of this research is to create a fast and dexterous robotic catheter system that can perform surgery on the delicate structures inside of the beating heart. PMID:21874124

    Central venous catheters are of an essential importance to critically ill patients who require long-term venous access for various purposes. Their use made the treatment much easier, but still they are not harmless and are prone to numerous complications. Catheter infections represent the most significant complication in their use. The frequency of infections varies in different patient care settings, but their appearance mostly depends on the patient's health condition, catheter insertion time, localization of the catheter and type of the used catheter. Since they are one of the leading causes of nosocomial infections and related to significant number of morbidity and mortality in intensive care units, it is very important that maximal aseptic precautions are taken during the insertion and the maintenance period. Prevention of infection of the central venous catheters demands several measures that should be applied routinely.

    Full Text Available Central venous placement using ultrasound has significantly reduced the complications associated with blind puncture. The central venous catheter can still get misplaced if it follows an anomalous route after appropriate puncture of desired vessel. We report a case of misplaced dialysis catheter into the accessory hemiazygos vein which resulted in a large hemothorax, and we recommend the routine use of a fluoroscope for placement of dialysis catheters so as to avoid serious complications.

    Thirty-nine hemodialysis patients with permanent central venous catheters were analyzed for bacterial catheter colonization comparing different catheter-lock strategies. The closed needleless Tego connector with sodium chloride lock solution was significantly more frequently colonized with bacteria than the standard catheter caps with antimicrobially active citrate lock solution (odds ratio, 0.22 [95% confidence interval, 0.07-0.71]; P = .011).

    The aim of this study was to report catheter malposition during voiding cystourethrography. Eight hundred forty-three voiding cystourethrography (265 males and 578 females, aged 1 week to 12 years, mean age 2 years) were performed during a period of 4 years. The conventional standard procedure was applied. In 3 cases with passed history of urinary tract infection the catheter entered directly into the ureter. In all these cases the uretero-vesical reflux was present on the same side where the catheter entered. It appears that insertion of a catheter into the ureter is possible only in the presence of an anomaly or pathology at the vesicoureteric junction. (orig.)

    Serious analytic errors in potassium measurements have been identified in blood specimens obtained from newly inserted central catheters. Erroneous elevated readings have been related to interactions of chemistry analyzer electrodes and substances fixed to external and intraluminal walls of the central catheter. Anecdotal summaries of this phenomenon are presented to enable the nurse to recognize potential problems when sampling blood from central catheters. Studies were performed to determine the amount of flush necessary to clear the catheter of interfering residue. To eliminate this potentially hazardous occurrence, recommended flush volumes, nursing implications, and actions are described.

    Introduction Peripherally inserted central venous catheters (PICCs) may adversely impact future successful arteriovenous fistulae (AVF). As part of a quality improvement project, the performance of tunneled small bore tunneled central venous catheters (TSB-CVCs), as alternatives to PICCs, was evaluated. Methods A retrospective observational study, involving individuals ≥18 years of age who underwent TSB-CVC placement by Interventional Radiology at Mayo Clinic, Rochester, MN between 1/1/2010 and 8/30/2013. Findings The study cohort included 92 patients with a median age of 55 (46-67) years, who underwent 108 TSB-CVC placements. Baseline renal disease was present in 71% (77/108). Most TSB-CVCs were placed in hospitalized patients (94%; 102/108); five French in diameter (61%; 66/108) and located in an internal jugular vein (84%; 91/108). Median catheter indwelling time was 20 (11-43) days (n = 84). TSB-CVC-related bloodstream infection, deep venous thrombosis (DVT), and superficial venous thrombosis (SpVT) rates per line were 0.009 (1/108), 0.018 (2/108), and 0.009 (1/108), respectively. Venous outcomes in a subgroup of 54 patients, who had documented PICC placements (n = 161) in addition to TSB-CVC (n = 58) were compared. TSB-CVC-DVT rate was lower than the PICC-DVT rate (0.017 [1/58] vs. 0.106 per line [17/161]; P = 0.04). The TSB-CVC-SpVT rate was not different from the PICC-SpVT rate (0 [0/58] vs. 0.037 [6/161] per line; P = 0.14). Discussion TSB-CVCs demonstrated an excellent safety profile in our study. These catheters should be preferentially utilized for arm vein preservation in advanced kidney disease. Their impact on future AVF success needs further evaluation.

    Introduction: Ureteric stenting is a commonly used endourologic procedure for temporary and long-term drainage of an obstructed upper urinary tract. The indication for ureteric stenting is obstruction due to intrinsic (intraureteral stones, strictures, or tumors) or extrinsic (for example compressing pelvic or retroperitoneal mass) causes. Despite the fact that stents do certainly have proven benefits in all fields of urology, there are potential morbidities. The most common problem of indwelling ureteral stents is infection. As foreign body in the urinary system, stents act as a nidus for bacteria colonization, crystallization and encrustation. Bacteria induced biofilm formation predisposes for the crystallization of lithogenic salts, such as calcium-phosphate, calcium-oxalate, magnesium-phosphate on the surface initiating stent encrustation. It was the objective of this study to evaluate whether optical coherence tomography (OCT) using both the surface and the endoluminal technique is feasible to investigate the locations and degree of encrustation process in clinically used ureteral stents. Patients and methods: After removal from patients, fourteen polyurethane JJ stents were investigated. A fresh JJ served as a control. The external surfaces were examined using an endoscopic surface OCT whereas the intraluminal surfaces were investigated by an endoluminal radial OCT device. The focus was on detection of encrustation or crystalline sedimentation. Results: In 12 female and 2 male patients, the median indwelling time of the ureteral catheter was 100 days (range 19- 217). Using the endoluminal OCT, the size and grade of intraluminal encrustation could be expressed as a percentage relating to the open lumen of the reference stent. The maximum encrustation observed resulted in a remaining unrestricted lumen of 15-35% compared to the reference. The luminal reduction caused by encrustation was significantly higher at the proximal end of the ureteral stent as compared

    Intracardiac echocardiography (ICE) catheters enable high-quality ultrasound imaging within the heart, but their use in guiding procedures is limited due to the difficulty of manually pointing them at structures of interest. This paper presents the design and testing of a catheter steering model for robotic control of commercial ICE catheters. The four actuated degrees of freedom (4-DOF) are two catheter handle knobs to produce bi-directional bending in combination with rotation and translation of the handle. An extra degree of freedom in the system allows the imaging plane (dependent on orientation) to be directed at an object of interest. A closed form solution for forward and inverse kinematics enables control of the catheter tip position and the imaging plane orientation. The proposed algorithms were validated with a robotic test bed using electromagnetic sensor tracking of the catheter tip. The ability to automatically acquire imaging targets in the heart may improve the efficiency and effectiveness of intracardiac catheter interventions by allowing visualization of soft tissue structures that are not visible using standard fluoroscopic guidance. Although the system has been developed and tested for manipulating ICE catheters, the methods described here are applicable to any long thin tendon-driven tool (with single or bi-directional bending) requiring accurate tip position and orientation control.

    Full Text Available Pulmonary artery catheter is widely used in intensive care. Distal migration of the catheter is a know complication. Diagnosis of such a migration is made by both clinical criteria and radiographs. A 55 year old septic lady was admitted to the intensive care unit. Pulmonary artery catheter introduced for cardiac output monitoring migrated from right lung to left lung. Diagnosis was made following a chest radiograph the following day of insertion with the clinical criteria remaining unaltered. Migration of pulmonary artery catheter can occur not only distally but from one lung to another. Clinical criteria alone cannot rule out migration. Chest radiographs form an important part in monitoring the position of the pulmonary artery catheter.

  18. Central Venous Catheter-Related Hydrothorax

    2015-11-01

    Full Text Available This report describes a case of 88-year-old women who developed central venous catheter-related bilateral hydrothorax, in which left pleural effusion, while right pleural effusion was being drained. The drainage prevented accumulation of fluid in the right pleural space, indicating that there was neither extravasation of infusion fluid nor connection between the two pleural cavities. The only explanation for bilateral hydrothorax in this case is lymphatic connections. Although vascular injuries by central venous catheter can cause catheter-related hydrothorax, it is most likely that the positioning of the tip of central venous catheter within the lymphatic duct opening in the right sub-clavian-jugular confluence or superior vena cava causes the catheter-related hydrothorax. Pericardial effusion can also result from retrograde lymphatic flow through the pulmonary lymphatic chains.

    For modern medicine central venous catheters play an important role for diagnostic and therapeutic options. Catheter implantation, complication detection and therapy of catheter complications are an increasing demand for the radiologist. The review article provides an overview of different catheter types, their indications, advantages and disadvantages. Catheter malpositions are usually detectable in conventional X-ray. Most malpositions are correctable using interventional-radiological techniques. In addition therapeutical options for thrombotic complications (venous thrombosis, catheter occlusion, fibrin sheath) are discussed. In case of an infectious catheter complication, usually a catheter extraction and re-implantation is necessary.

    1981-02-01

    A commercially available polyvinyl chloride intravenous catheter was studied in 9 horses for 3 to 10 days to evaluate the catheter's suitability for use in the horse, to develop a new insertion technique, and to establish a protocol for catheter care. Seven of the animals were clinically normal horses receiving parenteral nutrition; one was a horse with hypocalcemia receiving frequent intravenous injections of calcium gluconate, and one was a clinically normal horse receiving no infusions. The catheter dressings were changed every 48 hours, and an aspirate from the catheter and the catheter tip was cultured at the time of catheter removal. One catheter became infected following a break in the protocol. It was concluded that the polyvinyl catheter is suitable for use in the horse and that the proposed protocol for catheter insertion and maintenance may reduce the likelihood of complications such as catheter sepsis, thrombophlebitis, and embolism.

    Increased incidence of cancers and the development of totally implanted venous access devices that contain their own port to deliver chemotherapy will lead to a greater than before numbers of central venous catheter-related thrombosis (CVCT). Medical consequences include catheter dysfunction and pulmonary embolism. Vessel injury caused by the procedure of CVC insertion is the most important risk factor for development of CVCT. This event could cause the formation of a fresh thrombus, which is reversible in the large majority of patients. In some cases, thrombus formation is not related to catheter insertion. The incidence of CVC-related DVT assessed by venography has been reported to vary from 30 to 60% but catheter-related DVT in adult patients is symptomatic in only 5% of cases. The majority of patients with CVC-related DVT is asymptomatic or has nonspecific symptoms: arm or neck swelling or pain, distal paresthesias, headache, congestion of subcutaneous collateral veins. In the case of clinical suspicion of CVC-related deep venous thrombosis (DVT), compressive ultrasonography (US), especially with doppler and color imaging, currently is first used to confirm the diagnosis. Consequently, contrast venography is reserved for clinical trials and difficult diagnostic situations. There is no consensus on the optimal management of patients with CVC-related DVT. Treatment of CVC-related VTE requires a five- to seven-day course of adjusted-dose unfractionated heparin or low molecular weight heparin (LMWH) followed by oral anticoagulants. Long-term LMWH that has been shown to be more effective than oral anticoagulant in cancer patients with lower limb DVT, could be used in these patients. The efficacy and safety of pharmacologic prophylaxis for CVC related thrombosis is not established and the last recommendations suggest that clinicians not routinely use prophylaxis to try to prevent thrombosis related to long-term indwelling CVCs in cancer patients.

    Malignant pleural effusions in the presence of trapped lung remain notoriously difficult to treat. Various methods exist ranging from minimally invasive procedures including repeated needle thoracocentesis to the need for a formal surgical procedure such as placement of a pleuroperitoneal shunt and even thoracotomy and decortication. Controversy exists as to what is the optimum treatment for this condition. Any planned treatment should balance the therapeutic benefit provided against convalesce for a disease with a limited life expectancy. Patients should not spend a significant proportion of their remaining life span recovering from palliative procedures. In a series of patients with malignant pleural effusion the medial survival time was 20 weeks, with 30 days and 1 year mortality rates of 12.8% and 83.6%, respectively. We describe our five-year experience with the use of indwelling PleurX catheters in patients with malignant pleural effusions in the presence of confirmed trapped lung on radiological or VATS investigation. Patient health related quality of life was investigated by telephone questionnaire. The parameters analysed were symptomatic relief, mobility and ease of management following insertion. One hundred and sixteen patients underwent PleurX catheter insertion by a single operator, 48 questionnaires were completed. Of the 48 cases analysed, improvement in all three quality of life indices was recorded following catheter insertion.

    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.

    To evaluate the efficacy and safety of fluoroscopy-guided, radiologic placement of a tunneled central venous catheter into the superior vena cava (SVC). Thirty five patients underwent tunneled central venous catheter placement to facilitate long-term chemotherapy. They included 33 leukemic patients, one colon cancer patient, and one multiple myeloma patient. After confirming central venous patency with a injection of contrast media via the peripheral cephalic or basilic vein in the wrist joint, the subclavian vein was punctured under fluoroscopic guidance. A 7F double lumen TPN catheter was placed into the SVC through a subcutaneous tunnel in the anterior chest wall. Catheter placements were successful in all patients. The mean procedure time was 17.2minutes, mean fluooscopy time was 1.3minutes, mean number of punctures was 1.4, and mean volume of injhected contrast media was 43.5cc. Only two of all leukemic patients developed mild hematomas at the puncture site, but these soon resolved themselves. None of the patients developed pneumothorax or hemothorax. But late complications included local infection in two patients (6%) and thrombotic occlusion of the catheter in one (3%). The occluded catheter was successfully recanalized with Urokinase infusion. Fluoroscopy-guided, radiologic placement of a tunneled central venous catheter is an easy and safe method, and useful for patients requiring long-term venous access.

    Intestinal nutrition can be administered orally or by means of a catheter; the latter method is the focus of this article. The authors' objective is to provide up-to-date information in a succinct manner about the enteral feeding technique. The authors hope health professionals know the advantages as well as the inconveniences of the latest intestinal nutrition advances regarding access ways and the means to administer these. Intestinal nutrition formulas will not be dealt with in this article. However, a health professional should know that there is a wide variety of diets available depending on the complexity of macronutrients included in a diet, the quantity of proteins in a mixture, and that these are designed, in addition to feeding, to treat the specific pathological process a patient suffers from, such as diabetes of cancer.

    Thirty-one carotid artery stenoses were produced in thirty dogs by three different techniques. Twenty-three of these could be cured by transfemoral percutaneous catheter dilatation. High grade tight stenoses may present resistance which cannot be overcome by the catheter. Histological examination of the dilated vessels showed circumscribed changes in the vessel wall, with destruction of elastic membranes. From our experience of catheter dilatation of pelvic and lower limb arteries and of renal arteries, we consider it feasible to use this technique in selected patients with carotid stenosis.

    Objective To assess the symptoms of patients due to indwelling double ureteral stent and their impact on quality of life. Methods Sixty patients were assessed by the specific questionnaire. Average time of indwelling stent was 21.4 d. All patients finished the special questionnaire when the stent was removed by cystoscope, including specific urinary symptoms, IPSS (international prostate symptom score), VAS (visual analogic scale) and QOL (quality of life). To assess the pain feeling, the patients were divided into 3 groups by varied methods of anesthesia, including local anesthesia, balance anesthesia and general anesthesia. Results Insertion or removal of ureteral stents with local anesthesia provoked pain in 11 of 12 (91%) patients and 8 of 10 (80%) patients in balance anesthesia group. But 38 patients of general anesthesia group did not feel any pain when inserting stents. In 54 of 60 (90%) patients, the indwelling catheter provoked one or several urinary symptoms: nocturia (70%), frequency (65%), urgency (60%), tenesmus (58%), dysuria (52%), hematuria (35 % ) and incontinence (30 %). 75 % of the patients experienced pain, in the flank and lower abdomen. 29 (48 %) patients were found to be unsatisfied with their quality of life due to the indwelling stent. Among them, 18 (62%) patients demonstrated that the provoked overactive bladder symptoms were the main influence factor of QOL, compared with 5(17 %) patients complaining pain feeling. Conclusions Urinary symptoms and pain associated with indwelling double J ureteral stents could interfere the daily activities and 50 % of patients were found reduced quality of life. Overactive bladder symptoms were the main influence of QOL during the time of indwelling stent.%目的 探讨输尿管留置双J管对患者生活质量的影响因素.方法 60例留置输尿管双J管患者,平均年龄53岁.平均置管时间(21.4±3.8)d.患者门诊膀胱镜下拔管时应用输尿管支架管特殊调查问卷调查,包括

    All hemodialysis patients with temporary or permanent double lumen catheters are at risk for catheter occlusion. Clinical outcomes and cost-effectiveness of using urokinase, a thrombolytic agent, to declot occluded double lumen dialysis catheters were evaluated for 2 years. Patency was restored in 95 of 102 catheters. These data support the use of urokinase to safely and effectively restore patency, thereby extending the length of time a catheter can be used for dialysis.

    Minimally invasive surgery (MIS) is an approach whereby procedures conventionally performed with large and potentially traumatic incisions are replaced by several tiny incisions through which specialized instruments are inserted. Early MIS, often called laparoscopic surgery, used video cameras and laparoscopes to visualize and control the medical devices, which were typically cutting or stapling tools. More recently, catheter-based procedures have become a fast growing sector of all surgeries. In these procedures, small incisions are made into one of the main arteries (e.g. femoral artery in the thigh), and a long thin hollow tube is inserted and positioned near the target area. The key advantage of this technique is that recovery time can be reduced from months to a matter of days. In the United States, over 700,000 catheter procedures are performed annually representing a market of over $350 million. Further growth in this area will require significant improvements in the current catheter technology. In order to effectively navigate a catheter through the tortuous vessels of the body, two capabilities must exist: imaging and positioning. In most cases, catheter procedures rely on radiography for visualization and manual manipulation for positioning of the device. Radiography provides two-dimensional, global images of the vasculature and cannot be used continuously due to radiation exposure to both the patient and physician. Intravascular ultrasound devices are available for continuous local imaging at the catheter tip, but these devices cannot be used simultaneously with therapeutic devices. Catheters are highly compliant devices, and manipulating the catheter is similar to pushing on a string. Often, a guide wire is used to help position the catheter, but this procedure has its own set of problems. Three characteristics are used to describe catheter maneuverability: (1) pushability -- the amount of linear displacement of the distal end (inside body) relative to

He went out socializing during which he consumed large volumes of alcohol but did not take any recreational drugs. The following morning, he noticed distension of the lower abdomen and passed urine in dribbles. He then developed a temperature and became unwell. He was seen by district nurses and a doctor, who prescribed antibiotics. He continued to feel unwell. After 8 days, he referred himself to a spinal unit at Regional Spinal Injuries Centre, Southport. The blood test results showed the following: blood urea: 19.8 mmol/L; creatinine: 172 µmol/L; and C-reactive protein: 336.4 mg/L. Urethral catheterization led to immediate drainage of 1,400 mL of urine. A computed tomography scan revealed an enlarged, swollen left kidney, indicating acute bacterial nephritis. He was prescribed intravenous fluids and Meropenem. Creatinine decreased to 46 µmol/L.Conclusion: Spinal cord injury patients using condom catheters should be made aware of the risk of urine retention when they consume large amounts of alcoholic drinks in a short period of time. Patients and caregivers should be informed to consider intermittent catheterizations for 24–48 hours or insert indwelling urethral catheter when planning for an evening out.Keywords: spinal cord injury, tetraplegia, neuropathic urinary bladder, acute kidney injury

  3. Toxic catheters and urethral strictures: A concern about types of catheters used in resource-poor countries

    Directory of Open Access Journals (Sweden)

    A.A. Popoola

    2012-12-01

    Full Text Available Various reports in the literature have confirmed urethral toxicity caused by the use of catheters, mostly latex catheters and their coated versions, resulting in long-segment urethral strictures or strictures located in multiple areas of the urethra. Most catheters used in resource-poor countries, such as Nigeria, are latex catheters with various coatings, such as silicone. The reasons for the widespread use of these potentially toxic catheters are mainly non-availability and/or the high cost of less toxic catheters. We report three cases of urethral strictures following the use of siliconized latex catheters in order to highlight the potential urethral toxicity associated with the use of latex catheters and to draw the authorities’ attention to the need to regulate the types of catheters used in the country.

    Background A novel remotely controlled steerable guide catheter has been developed to enable precise manipulation and stable positioning of any eight French (Fr) or smaller electrophysiological catheter within the heart for the purposes of mapping and ablation. Objective To report our initial experience using this system for remotely performing catheter ablation in humans. Methods Consecutive patients attending for routine ablation were recruited. Various conventional diagnostic catheters were inserted through the left femoral vein in preparation for treating an accessory pathway (n = 1), atrial flutter (n = 2) and atrial fibrillation (n = 7). The steerable guide catheter was inserted into the right femoral vein through which various irrigated and non-irrigated tip ablation catheters were used. Conventional endpoints of loss of pathway conduction, bidirectional cavotricuspid isthmus block and four pulmonary vein isolation were used to determine acute procedural success. Results Ten patients underwent remote catheter ablation using conventional and/or 3D non-fluoroscopic mapping technologies. All procedural endpoints were achieved using the robotic control system without manual manipulation of the ablation catheter. There was no major complication. A radiation dosimeter positioned next to the operator 2.7 m away from the X-ray source showed negligible exposure despite a mean cumulative dose area product of 7,281.4 cGycm2 for all ten ablation procedures. Conclusions Safe and clinically effective remote navigation of ablation catheters can be achieved using a novel remotely controlled steerable guide catheter in a variety of arrhythmias. The system is compatible with current mapping and ablation technologies Remote navigation substantially reduces radiation exposure to the operator.

    Catheter path reconstruction is a necessary step in many clinical procedures, such as cardiovascular interventions and high-dose-rate brachytherapy. To overcome limitations of standard imaging modalities, electromagnetic tracking has been employed to reconstruct catheter paths. However, tracking errors pose a challenge in accurate path reconstructions. We address this challenge by means of a filtering technique incorporating the electromagnetic measurements with the nonholonomic motion constraints of the sensor inside a catheter. The nonholonomic motion model of the sensor within the catheter and the electromagnetic measurement data were integrated using an extended Kalman filter. The performance of our proposed approach was experimentally evaluated using the Ascension's 3D Guidance trakStar electromagnetic tracker. Sensor measurements were recorded during insertions of an electromagnetic sensor (model 55) along ten predefined ground truth paths. Our method was implemented in MATLAB and applied to the measurement data. Our reconstruction results were compared to raw measurements as well as filtered measurements provided by the manufacturer. The mean of the root-mean-square (RMS) errors along the ten paths was 3.7 mm for the raw measurements, and 3.3 mm with manufacturer's filters. Our approach effectively reduced the mean RMS error to 2.7 mm. Compared to other filtering methods, our approach successfully improved the path reconstruction accuracy by exploiting the sensor's nonholonomic motion constraints in its formulation. Our approach seems promising for a variety of clinical procedures involving reconstruction of a catheter path.

    With the success of percutaneous abdominal abscess drainage, attention is now being focused on the use of similar techniques in the thorax. We studied to evaluate the effect of percutaneous drainage in parenchymal fluid collections in the lungs. We performed percutaneous drainage of abscesses and other parenchymal fluid collections of the lungs in 15 patients. All of the procedures were performed under the fluoroscopic guidance with an 18-gauge Seldinger needle and coaxial technique with a 8-10F drainage catheter. Among 10 patients with lung abscess, 8 patients improved by percutaneous catheter drainage. In one patient, drainage was failed by the accidental withdrawal of the catheter before complete drainage. One patient died of sepsis 5 hours after the procedure. Among three patients with complicated bulla, successful drainage was done in two patients, but in the remaining patient, the procedure was failed. In one patient with intrapulmonary bronchogenic cyst, the drainage was not successful due to the thick internal contents. In one patient with traumatic hematoma, after the drainage of old blood clots, the signs of infection disappeared. Overally, of 14 patients excluding one who died, 11 patients improved with percutaneous catheter drainage and three patients did not. There were no major complications during and after the procedure. We conclude that percutaneous catheter drainage is effective and safe procedure for the treatment of parenchymal fluid collections of the lung in patients unresponsive to the medical treatment.

    Current clinical practice is characterised for importance of the patient's quality of life and the need to reduce the costs of their treatment. We search intravenous therapy alternatives that meet the needs of the patient, reducing the complications associated with the use of venous catheters. Scientific evidence shows that there are midline venous catheters that offer patients and professionals the possibility of extending the duration of infusion therapy, using more venous compatibility materials, and with less risk of infection. The Midlines are becoming in a safe an efficient device for intravenous therapy, continuous and intermittent infusion, provided the necessary care by expert nurses. Midline catheters are peripheral venous access devices between 3 to 10 inches in length (8 to 25 cm). Midlines are usually placed in an upper arm vein, such as the brachial or cephalic, and the distal extreme ends below the level of the axillary line. Midlines catheters implanted in the cephalic or deep basilica veins get more blood flow. This large blood volume justifies the lower risk of mechanical or chemical phlebitis. Midlines are routinely used for two to six weeks. Due that the extrem of these catheters does not extend beyond the axillary line, there are limitations for its use: type of infused drugs, velocity of infusion, etc. In general, solutions that have pH 5 to 9, or an osmolarity less than 500 mOsm are appropriate for infusion through a Midline. Its use is recommended in case of treatments over 7 days with low irritant capacity fluids. According to the Infusion Nurses Society's standards of practice, Midline catheters are appropriate for all intravenous fluids that would normally be administered through a short peripheral IV Importantly, due that the catheter does not pass through the central veins, Midlines can be placed without a chest X-ray to confirm placement. For certain situations, Midlines are suitable for acute units and even for care home settings

    The purpose of this study was to report our experience of percutaneous retrieval of dislodged port catheters with concurrent use of pigtail and loop snare catheters. During a 5-year period at our institute (June 2005 to July 2010), a total of 23 dislodged port catheters were retrieved. The interval between port catheter implantation and dislodged catheter retrieval ranged from 43 days to 1,414 days (mean 586.7 days). The time of delayed retrieval ranged from 1 day to 45 days (mean 4.6 days). All dislodged catheters were retrieved with the concurrent use of pigtail and loop snare catheters via femoral venous route. The prevalence of port catheter dislodgement at our institute was 3.4%. All dislodged port catheters were removed successfully with pigtail and loop snare catheters together. No procedure-related complications were encountered, except for transient arrhythmia in two patients, which required no medication. In conclusion, the concurrent use of pigtail and loop snare catheters is a feasible and easy way for percutaneous retrieval of a dislodged central venous port catheter.

    2011-01-01

    Full Text Available Introduction. Peritoneal dialysis is one of the modalities used for treatment of end-stage chronic kidney failure. Nowadays, this method is complementary to haemodialysis and renal transplantation. Owing to the rich vascularization of the peritoneum, it is used in the processes of osmosis and diffusion, enabling the removal of uremic material from the body. The procedure includes introduction of peritoneal fluid via the peritoneal catheter. Complications. The catheter is placed through the anterior abdominal wall with its tip positioned in the small pelvis. There are several techniques for catheter placement considered minimally invasive, which, however, may be associated with various complications. These complications can be divided into mechanical (catheter dysfunction, cuff protrusion, hernia, dialysate leaks, visceral perforation and infectious (early peritonitis, exit site or tunnel infection, surgical wounds. In most cases, such complications are rare and can be successfully managed using conservative therapy; however, in some situations severe complications can endanger the life of the patient. On-time recognition of complications, particularly in patients at risk, is of paramount importance for an effective treatment. The development of complications can increase the morbidity and the chance of treatment failure, and therefore transfer to haemodialysis. Conclusion. The preoperative evaluation and determination of the risk factors as well as the early recognition and adequate management of complications are essential in their prevention.

"n"nCase presentation: A lumbar epidural catheter inserted in a 17 year-old man for applying anesthesia for internal fixation of femur fracture and subsequent postoperative epidural analgesia. In the third postoperative day, during unsuccessful attempt for removing the catheter, it was broken and was retained in his back. A CT- scan was performed and shows a fragment of catheter in the sub- laminar ligament between L3 and L4 without any connection with epidural space. As the patient had no complaint the fractured fragment was left in site and he was just followed up in the clinic."n"nConclusion: The knowledge of practical method in locating the retained epidural catheter, and the indication for surgical removal are very important. CT- scan is useful in showing the mechanism and locating the epidural catheter entrapment and facilitating surgical follow-up.

    Primary misplaced or secondary flipped implanted catheters are located mostly in the right jugular vein. We demonstrate an effective method to replace fix implanted catheters such as Ports, Grochomg or Hickman catheters. Using a femoral venous approach, replacement into the superior vena cava can easily be done with a Sidewinder 1 catheter which is hooked over the misplaced central venous approach. In all our patients the method was successful. The repositioning technique described is simple, fast and has low costs. We can keep sterile conditions and do not need to solve the catheters' fixation. (orig.)

    The purpose of this study was to evaluate retrospectively the safety and effectiveness of radiologically placed tunneled peritoneal catheter in palliation of malignant ascites. Between July 2005 and June 2009, 41 tunneled peritoneal catheters were placed under ultrasonographic and fluoroscopic guidance in 40 patients (mean age, 55 years; 22 women) who had symptomatic malignant ascites. No procedure related mortality was observed. Major complication occurred in one patient (2.5%) in the form of serious bacterial peritonitis that necessitated catheter removal. Minor complications such as minor bacterial peritonitis, catheter dislodgement, tunnel infection, and catheter blockage occurred in 11 patients (27.5%). The mean duration of survival after catheter placement was 11.8 weeks. All patients expired of their primary malignancies in the follow-up. Radiologically placed tunneled peritoneal catheter is safe and effective in palliation of symptomatic malignant ascites.

  11. The bowed catheter sign: a risk for pericardial tamponade

    The use of a central venous catheter (CVC) has become commonplace in the care of children with a wide variety of medical and surgical problems. Complications resulting from the insertion of these catheters are well recognized and can be life-threatening. When a temporary CVC or other catheter is inserted into the central venous system it is secured to the skin with a combination of sutures and sterile dressing. This fixes the catheter in place and does not allow it to retract, thereby putting pressure on the right atrial wall via the catheter tip if it is too long. The probability of wall penetration is increased if a catheter or device is tapered at the point of contact. The purpose of this case report is to present the bowed catheter sign and to review the anatomy of the cavotricuspid isthmus, a possible predisposing factor to cardiac perforation and tamponade.

    Introduction Peripheral venous catheters (PVC) are medical devices most frequently used during hospital care. Although the frequency of specific PVC-related adverse events (PVCAEs) has been reported, the global risk related to the insertion of this device is poorly estimated. The aim of this study is to determine the incidence of PVCAEs during the indwell time, after catheter removal, and to identify practice-mirroring risk factors. Methods A prospective observational study was conducted as a part of a research project, called CATHEVAL, in one surgery ward and four medicine wards from three public general tertiary care hospitals in Northern France that were invited to participate between June-2013 and June-2014. Each participating ward included during a two-month study period all patients older than 15 years carrying a PVC. All inserted PVCs were monitored from insertion of PVC to up to 48 hours after removal. Monitored data included several practice-mirroring items, as well as the occurrence of at least one PVCAE. A multivariate Cox proportional hazard model, based on a marginal risk approach, was used to identify factors associated with the occurrence of at least one PVCAE. Results Data were analysed for 815 PVCs (1964 PVC-days) in 573 patients. The incidence of PVCAE was 52.3/100 PVCs (21.9/100 PVC-days). PVCAEs were mainly clinical: phlebitis (20.1/100 PVCs), haematoma (17.7/100 PVCs) and liquid/blood escape (13.1/100 PVCs). Infections accounted for only 0.4/100 PVCs. The most frequent mechanical PVCAEs, was obstruction/occlusion of PVC (12.4/100 PVCs). The incidence of post-removal PVCAEs was 21.7/100 PVCs. Unstable PVC and unclean dressing were the two main risk factors. Conclusion Limitation of breaches in healthcare quality including post-removal monitoring should be reinforced to prevent PVC-related adverse events in hospital settings. PMID:28045921

    OBJECTIVE To study the related risk factors of central venous catheter-related infection in the elderly patient with critical diseases. METHODS A total of 160 elderly patients with critical diseases were retrospectively analyzed. Multiple factor non-conditional logistic regression analysis was performed for the related factors that may lead to the central venous catheter-related infections. RESULTS The incidence of central venous catheter infections in 160 elderly patients with critical diseases was 35. 6%(57 cases). The incidence of central venous catheter infections was mainly related to the age,APACHEⅡ score, the site of indwelling catheter, the number of catheter cavity, intravenousalimentation treatment, the duration of indwelling catheterization and coexistence with other site infections (P<0. 05 or 0. 01); logistic regression analysis revealed that APACHEⅡ score, intravenousalimentation treatment, the duration of indwelling catheter, and coexistence with other site infections were the independent risk factors for the central venous catheter-related infections in the elderly patients with critical diseases. CONCLUSION It is necessary to develop the prevention programs and actively treat and reduce the incidence of infections in accordance with the independent risk factors for the central venous catheter-related infections in the elderly patients with critical disease so as to improve the patients' prognosis.%目的 探讨影响老年危重症患者中心静脉导管相关性感染发生的危险因素.方法 回顾性分析医院160例老年危重症患者的临床资料,对可能影响中心静脉导管相关性感染发生的因素进行多因素非条件logistic回归分析.结果 160例老年危重症患者中,发生中心静脉导管相关性感染57例,发生率35.6%;老年危重症患者中心静脉导管相关性感染的发生与年龄、APACHEⅡ评分、导管留置部位、导管腔数、是否有静脉营养操作、导管留置时间及

    We evaluated the technical success and complication rates associated with the radiological placement of tunneled central venous catheters in pediatric patients. Between May 1, 2005 and March 31, 2008, a total of 46 tunneled central venous catheters were placed in 34 children (M:F = 22:12; mean age, 9.9 years [9 months to 16.8 years]). All procedures were performed under ultrasonographic and fluoroscopic guidance. Follow-up data were obtained through the retrospective review of the medical records. We used the Kaplan-Meier survival method for the evaluation of survival rate of the catheters. All procedures were technically successful. The observed periprocedural complications included hematoma formation in three patients. The mean catheter life was 189.3 days (total, 8710 days; range, 7-810). Catheters were removed due to death (n=9), the end of treatment (n=8), catheter sepsis (n=4), malfunction (n=8), and accidental removal (n=4). The rate of catheter sepsis and malfunction was 0.459 and 0.919 for every 1000 catheter days, respectively. The expected mean catheter life was 479.6 days as per the Kaplan- Meier analysis. The results suggest that the radiologic placement of a tunneled central venous catheter is an effective technique with a high technical success rate and low complication rate.

    The purpose of this study was to evaluate in vitro safety of the novel tosufloxacin (TOS)-treated catheters with the prolonged antimicrobial activity. The test samples of silicone latex catheter were prepared by the immobilization of TOS on chitosan (CHIT)-coated catheter by means of covalent bonds and non-covalent interactions. Each step of the modification process of catheter surface was observed using ATR–Fourier transform infrared spectroscopy. In vitro cytotoxicity of the modified and unmodified catheters was assessed by direct and indirect tests in accordance with ISO standards using green monkey kidney (GMK) cell line. The MTT, lactate dehydrogenase activity (LDH), WST-8, Sulforhodamine B (SRB) test results and microscopic observation clearly indicated that unmodified silicone latex catheters decrease cell metabolic activity, act as a cytotoxic agent causing cell lysis and induce cell death through necrotic or apoptotic process. We suggest that chitosan coat with TOS immobilized limits leaching of harmful agents from silicone latex material, which significantly enhances survivability of GMK cells and therefore is quite a good protection against the cytotoxic effect of this material. - Highlights: • Characterization of the novel antimicrobial urinary catheters • Monitoring of the catheter modification by FTIR analysis • Confirmation of high cytotoxicity of latex-based catheter used in urological practice • Chitosan-coated and tosufloxacin-treated catheter is less toxic than the untreated one. • The proposed surface modification protects cells against latex-induced death.

    This paper highlights the methodology in measuring interstitial pressure in pancreatic adenocarcinoma tumors. A Millar Mikrotip pressure catheter (SPR-671) was used in this study and a system was built to amplify and filter the output signal for data collection. The Millar pressure catheter was calibrated prior to each experiment in a water column at 37°C, range of 0 to 60 inH2O (112 mmHg), resulting in a calibration factor of 33 mV / 1 inH2O. The interstitial pressures measured in two orthotopically grown pancreatic adenocarcinoma tumor were 57 mmHg and 48 mmHg, respectively. Verteporfin uptake into the pancreatic adenocarcinoma tumor was measured using a probe-based experimental dosimeter.

    Infectious biofilms are problematic in many healthcare-related devices and are especially challenging and ubiquitous in urinary catheters. This report presents an on-demand fouling-release methodology to mechanically disrupt and remove biofilms, and proposes this method for the active removal of infectious biofilms from the previously inaccessible main drainage lumen of urinary catheters. Mature Proteus mirabilis crystalline biofilms detach from silicone elastomer substrates upon application of strain to the substrate, and increasing the strain rate increases biofilm detachment. The study presents a quantitative relationship between applied strain rate and biofilm debonding through an analysis of biofilm segment length and the driving force for debonding. Based on this mechanism, hydraulic and pneumatic elastomer actuation is used to achieve surface strain selectively within the lumen of prototypes of sections of a fouling-release urinary catheter. Proof-of-concept prototypes of sections of active, fouling-release catheters are constructed using techniques typical to soft robotics including 3D printing and replica molding, and those prototypes demonstrate release of mature P. mirabilis crystalline biofilms (e.g., ≈90%) from strained surfaces. These results provide a basis for the development of a new urinary catheter technology in which infectious biofilms are effectively managed through new methods that are entirely complementary to existing approaches.

    The authors report an unusual case of intrathecal baclofen withdrawal due to the perforation and subsequent leakage of a baclofen pump catheter in a patient with spastic cerebral palsy. A 15-year-old boy underwent an uncomplicated placement of an intrathecal baclofen pump for the treatment of spasticity due to cerebral palsy. After excellent control of symptoms for 3 years, the patient presented to the emergency department with increasing tremors following a refill of his baclofen pump. Initial evaluation consisted of radiographs of the pump and catheter, which appeared normal, and a successful aspiration of CSF from the pump's side port. A CT dye study revealed a portion of the catheter directly overlying the refill port and extravasation of radiopaque dye into the subfascial pocket anterior to the pump. During subsequent revision surgery, a small puncture hole in the catheter was seen to be leaking the drug. The likely cause of the puncture was an inadvertent perforation of the catheter by a needle during the refilling of the pump. This case report highlights a unique complication in a patient with an intrathecal baclofen pump. Physicians caring for these patients should be aware of this rare yet potential complication in patients presenting with baclofen withdrawal symptoms.

    ABSTRACT Objective: to investigate the incidence of phlebitis and its association with risk factors when using peripheral IV catheters (PIC) and following their removal - (post-infusion phlebitis) in hospitalized adults. Method: a cohort study of 171 patients using PIC, totaling 361 punctures. Sociodemographic variables and variables associated with the catheter were collected. Descriptive and analytical statistical analyses were performed. Results: average patient age was 56.96 and 51.5% of the sample population was male. The incidence of phlebitis was 1.25% while using PIC, and 1.38% post-infusion. The incidence of phlebitis while using PIC was associated with the length of time the catheter remained in place, whereas post-infusion phlebitis was associated with puncture in the forearm. Ceftriaxone, Clarithromycin and Oxacillin are associated with post-infusion phlebitis. Conclusions: this study made it possible to investigate the association between risk factors and phlebitis during catheter use and following its removal. The frequency of post-infusion phlebitis was larger than the incidence of phlebitis with the catheter in place, with Phlebitis Grade III and II being the most frequently found in each of these situations, respectively. Aspects related to post-infusion phlebitis can be explained, given the limited number of studies addressing this theme from this perspective. PMID:27508916

    Objective: to report the application of GPⅡb/Ⅲa antagonist (Integrilin) in peri-opercuta-neous transluminal catheter angioplasty and stent implantation in Chinese. Method: Twenty-one patients who underwent percutaneous transluminal catheter angioplasty(PTCA) and stent implantation were included. After arterial puncture, integrilin was injected at dose of 180ug/kg, and then main-tained at 2μg/kg·min for 18 hours. Asprine, plavix(clopidogrel) and heparin were used at the same time. ACT, PT, KPTT and blood routine were routinely monitored. Results: All sheaths were drawn out 2 to 4 hours after the procedure.. There was no severe complication such as hematoma, acute and subacute thrombosis in coronary artery, or thrombocytopenia. ACT returned to less than 150 aeconds in 2 hours in 15 patients; in 4 hours in 6 patients. There was no significant difference between the preand post-procedure value of PT and platelet count. KPTT was significantly higher than pre-procedure value at 2 hours after the procedure . No recurrence of angina pectoris was observed in the first nine patients within one year follow-up, and no restenosis occurred in stents in the five patients who had coronary angiography one year later. Conclusion: Application of GPⅡb/Ⅲa receptor antagonist (Integrilin)in peri-parcutaneous transluminal catheter angioplasty and stent implantation in combination with aspirin and plavix could significantly reduce the dosage and duration of heparin with benefit of shortening the indwelling time of sheaths, but did not increase risk of bleeding or lead to thrombosis in stent.

    One of the main wishes in the field of urinary catheters and stents is to arm them with biodegradable characteristics because we consider a failure of these devices the need for retrieval, the forgotten catheter syndrome as well as the adverse effects permanent devices cause after fulfilling their aim. The efforts focused in new designs, coatings and biomaterials aim to increase the biocompatibility of theses internal devices. Lately, there have been correct advances to answer the main challenges regarding biodegradable ureteral devices. Thus, modulation of the rate of degradation has been achieved thanks to new biomaterials and the use of copolymers that enable to choose the time of permanence as it is programmed with conventional double J catheters. Biocompatibility has improved with the use of new polymers that adapt better to the urine. Finally, one of the main problems is elimination of degraded fragments and experimentally it has be demonstrated that new designs elicit controlled degradation, from distal to proximal; using stranding and combination of copolymers degradation may be caused by dilution, reducing fragmentation to the last stages of life of the prosthesis. Moreover, it has been demonstrated that biodegradable catheters potentially may cause less urinary tract infection, less encrustation and predictably they will diminish catheter morbidity, since their degradation process reduces adverse effects. Regarding the development of biodegradable urethral stents, it is necessary to find biomaterials that enable maintaining their biomechanical properties in the long term, keeping open the urethral lumen both in patients with BPH and urethral stenosis. Modulation of the time of degradation of the prosthesis has been achieved, but the appearance of urothelial hyperplasia is still a constant in the initial phases after implantation. The development of drug eluting stents, anti-proliferative or anti-inflammatory, as well as biodegradable stents biocoated is a

  13. Technique of Peritoneal Catheter Placement under Fluroscopic Guidance

    Full Text Available Peritoneal catheters are mainly used for peritoneal dialysis in patients with end-stage renal disease. Other uses of this catheter include intraperitoneal chemotherapy and gene therapy for ovarian cancer and draining of uncontrolled refractory ascites in patients with liver cirrhosis. Traditionally, surgeons place most of these peritoneal catheters either by laparoscopy or open laparotomy. We detail our percutaneous approach to placing peritoneal catheters using fluoroscopic guidance. We emphasize the use of additional ultrasound guidance, including gray scale and color Doppler ultrasound, to determine the safest puncture site and to guide the initial needle puncture in order to avoid bowel perforation and injury to epigastric artery. We present our experience in placing peritoneal catheters using this technique in 95 patients with various indications. Fluoroscopic guided percutaneous placement of peritoneal catheters is a safe, minimally invasive, and effective alternative to open surgical or laparoscopic placement.

    Background Disinfection of the intraluminal space of single-lumen polymer tubes can be obtained by ultraviolet C (UVC) light exposure from an external light source. In existing catheters UVC disinfection is hampered by the design of the catheter hub and tube connector. Aim To demonstrate...... that it is possible to design a single-lumen catheter with a hub, tube connector and tube parts that can be UVC-disinfected throughout its entire lumen. Methods Two single-lumen catheters were designed: one control and one for UVC exposure. They were contaminated with Pseudomonas aeruginosa (104–105 cfu/mL) before...... UVC light exposure, sampling and plate counting. Findings Two minutes of UVC exposure was sufficient to obtain 4 log10 disinfection for the full-length prototype catheter. This exposure corresponds to ∼40 mJ/cm2 at the catheter tip and indicates that even shorter exposure times can be achieved...

    Condom catheters are often used in the management of male urinary incontinence, and are considered to be safe. As condom catheters are placed on the male genitalia, sometimes adequate care is not taken after placement owing to poor medical care of debilitated patients and feelings of embarrassment and shame. Similarly, sometimes the correct size of penile sheath is not used. Strangulation of penis due to condom catheter is a rare condition; only few such cases have been reported in the literature. Proper application and routine care of condom catheters are important in preventing this devastating complication especially in a neurologically debilitated population. We present a case of penile necrosis due to condom catheter. We will also discuss proper catheter care and treatment of possible complications.

  16. Conceptual Design and Procedure for an Autonomous Intramyocardial Injection Catheter.

    2016-12-07

    This article discusses existing catheter systems and proposes a conceptual design and procedure for an autonomous cellinjection catheter for the purpose of transferring committed myogenic or undifferentiated stem cells into the infarct boundary zones of the left ventricle. Operation of existing catheters used for cell delivery is far from optimal. Commercial injection catheters available are hand-held devices operated manually by means of tip deflection and torque capabilities. Interventionists require a hefty learning curve and often encounter difficulties in catheter stabilization and infarct detection, resulting in lengthy operation times and non-precise injections. We examined current technologies and proposed a design incorporating robotic positional control, feedback signals, and an adaptable operational sequence to overcome these problems. The design provides the basis for the construction of a robotic catheter that is able to autonomously assist the physician in transferring myogenic cells to the left ventricle infarct boundary zones.

    The insertion of central venous catheters is a common bedside procedure performed in intensive care units. Here, we present a case of an 82-year-old man who underwent insertion of a central venous catheter in the internal jugular vein without perceived complications. Postprocedural radiographs showed rostral migration of the catheter, and computed tomography performed coincidentally showed cannulation of the jugular bulb at the level of the jugular foramen. To our knowledge, this is the first report to document migration of a central venous catheter from the internal jugular vein into the dural sinuses, as confirmed by computed tomography. The case highlights the importance of acquiring postprocedural radiographs for all insertions of central venous catheters to confirm catheter placement.

    Accurate diagnosis of catheter-related bloodstream infection (CRBSI) is mandatory for hospital infection control. Peripherally inserted central venous catheters (PICCs) are widely used in intensive care units, but studies about procedures for detection of colonization are scarce in neonates. We sequentially processed 372 PICCs by 2 methods, first by the standard roll-plate (RP) technique and then by rubbing catheters on a blood agar plate after being longitudinally split (LS). With both techniques, we detected 133 colonized PICCs. Ninety-four events of CRBSI were diagnosed. The sensitivity, specificity, positive predictive value, and negative predictive value for detection of CRBSI were 58.5%, 92.8%, 73.3%, and 86.9%, respectively, for RP technique and 96.8%, 88.5%, 74.0%, and 98.8%, respectively, for LS technique. The LS technique increased the proportion of detected CRBSI by 38.3%. Neonatal PICC tips should be cultured after cutting them open. This technique is simple and sensitive to detect catheter colonization and also to diagnose CRBSI.

    Full Text Available CONTEXT: Totally implantable devices are increasingly being utilized for chemotherapy treatment of oncological patients, although few studies have been done in our environment to analyze the results obtained from the implantation and utilization of such catheters. OBJECTIVE: To study the results obtained from the implantation of totally implantable catheters in patients submitted to chemotherapy. TYPE OF STUDY: Prospective. SETTING: Hospital do Câncer A.C. Camargo, São Paulo, Brazil. METHODS: 519 totally implantable catheters were placed in 500 patients submitted to chemotherapy, with preference for the use of the right external jugular vein. Evaluations were made of the early and late-stage complications and patient evolution until removal of the device, death or the end of the treatment. RESULTS: The prospective analysis showed an average duration of 353 days for the catheters. There were 427 (82.2% catheters with no complications. Among the early complications observed, there were 15 pathway hematomas, 8 cases of thrombophlebitis of the distal stump of the external jugular vein and one case of pocket infection. Among the late-stage complications observed, there were 43 infectious complications (0.23/1000 days of catheter use, 11 obstructions (0.06/1000 days of catheter use and 14 cases of deep vein thrombosis (0.07/1000 days of catheter use. Removal of 101 catheters was performed: 35 due to complications and 66 upon terminating the treatment. A total of 240 patients died while the catheter was functioning and 178 patients are still making use of the catheter. CONCLUSION: The low rate of complications obtained in this study confirms the safety and convenience of the use of totally implantable accesses in patients undergoing prolonged chemotherapy regimes.

    Infections in skilled nursing facilities (SNFs) are common and result in frequent hospital transfers, functional decline, and death. Colonization with multidrug-resistant organisms (MDROs) - including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and multidrug-resistant gram-negative bacilli (R-GNB) - is also increasingly prevalent in SNFs. Antimicrobial resistance among common bacteria can adversely affect clinical outcomes and increase health care costs. Recognizing a need for action, legislators, policy-makers, and consumer groups are advocating for surveillance cultures to identify asymptomatic patients with MDROs, particularly MRSA in hospitals and SNFs. Implementing this policy for all SNF residents may be costly, impractical, and ineffective. Such a policy may result in a large increase in the number of SNF residents placed in isolation precautions with the potential for reduced attention by health care workers, isolation, and functional decline. Detection of colonization and subsequent attempts to eradicate selected MDROs can also lead to more strains with drug resistance. We propose an alternative strategy that uses a focused multicomponent bundle approach that targets residents at a higher risk of colonization and infection with MDROs, specifically those who have an indwelling device. If this strategy is effective, similar strategies can be studied and implemented for other high-risk groups.

    2013-04-01

    A remote catheter navigation system compatible with magnetic resonance imaging (MRI) has been developed to facilitate MRI-guided catheterization procedures. The interventionalist's conventional motions (axial motion and rotation) on an input catheter - acting as the master - are measured by a pair of optical encoders, and a custom embedded system relays the motions to a pair of ultrasonic motors. The ultrasonic motors drive the patient catheter (slave) within the MRI scanner, replicating the motion of the input catheter. The performance of the remote catheter navigation system was evaluated in terms of accuracy and delay of motion replication outside and within the bore of the magnet. While inside the scanner bore, motion accuracy was characterized during the acquisition of frequently used imaging sequences, including real-time gradient echo. The effect of the catheter navigation system on image signal-to-noise ratio (SNR) was also evaluated. The results show that the master-slave system has a maximum time delay of 41 ± 21 ms in replicating motion; an absolute value error of 2 ± 2° was measured for radial catheter motion replication over 360° and 1.0 ± 0.8 mm in axial catheter motion replication over 100 mm of travel. The worst-case SNR drop was observed to be 2.5%.

  14. Diagnosis and Rescue of a Kinked Pulmonary Artery Catheter

    Directory of Open Access Journals (Sweden)

    Nicolas J. Mouawad

    2015-01-01

    Full Text Available Invasive hemodynamic monitoring with a pulmonary catheter has been relatively routine in cardiovascular and complex surgical operations as well as in the management of critical illnesses. However, due to multiple potential complications and its invasive nature, its use has decreased over the years and less invasive methods such as transesophageal echocardiography and hemodynamic sensors have gained widespread favor. Unlike these less invasive forms of hemodynamic monitoring, pulmonary artery catheters require an advanced understanding of cardiopulmonary physiology, anatomy, and the potential for complications in order to properly place, manage, and interpret the device. We describe a case wherein significant resistance was encountered during multiple unsuccessful attempts at removing a patient’s catheter secondary to kinking and twisting of the catheter tip. These attempts to remove the catheter serve to demonstrate potential rescue options for such a situation. Ultimately, successful removal of the catheter was accomplished by simultaneous catheter retraction and sheath advancement while gently pulling both objects from the cannulation site. In addition to being skilled in catheter placement, it is imperative that providers comprehend the risks and complications of this invasive monitoring tool.

  15. Diagnosis of intra vascular catheter-related infection.

    2002-01-01

    The use of central vascular catheters (CVC) is associated with a substantial number of complications, amongst which infections predominate. A diagnosis of CVC-related infection usually requires catheter removal for culture. Semiquantitative (roll-plate method) and quantitative methods (flush, vortex, centrifugation or sonication methods) are the most reliable diagnostic methodologies requiring catheter removal, because of their greater specificity. The roll-plate method is the simplest and most commonly used technique. This method only samples the external surface of the catheter, and is particularly indicated for recently inserted catheters in which extraluminal colonisation is the primary mechanism of infection. Luminal culture techniques, such as the quantitative methods, may be more relevant for catheters that have been in place for a long period of time. However, in up to 85% of removed CVC the culture is negative, and other diagnostic techniques that do not require catheter removal have been proposed, including paired quantitative blood cultures, endoluminal brushing, and differential time to positivity (DTP) of paired blood cultures. DTP, that compares the time to positivity for qualitative cultures of blood samples simultaneously drawn from the CVC and a peripheral vein, appears to be the most reliable in the routine clinical practice since many hospitals use automatic devices for qualitative blood culture positivity detection. More recently catheter-sparing direct diagnostic methods, which include Gram stain and acridin-orange leucocyte cytospin (AOLC) test, appeared to be especially useful because of the rapidity of results and the ability to distinguish different microorganisms, allowing early targeted antimicrobial therapy.

  16. New tools in diagnosing catheter-related infections.

    Blot, F; Nitenberg, G; Brun-Buisson, C

    2000-07-01

    Clinical criteria alone are insufficient to allow a diagnosis of intravascular catheter-related sepsis (CRS). A definite diagnosis of CRS usually requires removal of the catheter for quantitative catheter tip culture. However, only about 15-25% of central venous catheters (CVC) removed because infection is suspected actually prove to be infected, and the diagnosis is always retrospective. Other diagnostic tests, such as differential quantitative blood cultures from samples taken simultaneously from the catheter and a peripheral vein, have been proposed to avoid unjustified removal of the catheter and the potential risks associated with the placement of a new catheter at a new site: a central-to-peripheral blood culture colony count ratio of 5:1 to 10:1 is considered indicative of CRS. Despite its high specificity, the latter diagnostic technique is not routinely used in clinical practice because of its complexity and cost. The measurement of the differential time to positivity between hub blood (taken from the catheter port) and peripheral blood cultures might be a reliable tool facilitating the diagnosis of CRS in situ. In an in vitro study, we found a strong relationship between the inoculum size of various microorganisms and the time to positivity of cultures. When the times to positivity of cultures of blood taken simultaneously from central and peripheral veins in patients with and without CRS were examined, we found that earlier positivity of central vs peripheral vein blood cultures was highly correlated with CRS. Using a cut-off value of +120 min, the "differential time to positivity" of the paired blood samples, defined as time to positivity of the peripheral blood minus that of the hub blood culture, had 91% specificity and 94% sensitivity for the diagnosis of CRS. This method may be coupled with other techniques that have high negative predictive value, such as skin cultures at the catheter exit site. This diagnostic test can be proposed for routine

    1998-12-01

    The well known negative effect of infection on nutrition causes the cycle 'infection-malnutrition-infection'. Prolonged parenteral nutrition requires central venous catheterization. Due to the possibility of 'catheter related sepsis' (CRS) catheters should be used correctly to avoid septic complications. A very high percentage of central venous catheters (CVC) removed because of presumed infections are not infected when culture is done. In some patients infections are successfully treated with antibiotics without catheter removal. Removal of the line is recommended when catheter-associated sepsis is suspected or proven, but not for the extremely ill preterm infant or when such removal may be impractical. A therapeutic protocol is suggested to avoid future canalizations in the neonate, sometimes in a critical situation. Current literature referring to CRS in the newborn infant is reviewed.

    2003-01-01

    Full Text Available Physician can obtain fetal heart rate, electrophysiological information, and uterine contraction activity for determining fetal status from an intrauterine catheters electrocardiogram with the maternal electrocardiogram canceled. In addition, the intrauterine catheter would allow physicians to acquire fetal status with one non-invasive to the fetus biosensor as compared to invasive to the fetus scalp electrode and intrauterine pressure catheter used currently. A real-time maternal electrocardiogram cancellation technique of the intrauterine catheters electrocardiogram will be discussed along with an analysis for the methods effectiveness with synthesized and clinical data. The positive results from an original detailed subjective and objective analysis of synthesized and clinical data clearly indicate that the maternal electrocardiogram cancellation method was found to be effective. The resulting intrauterine catheters electrocardiogram from effectively canceling the maternal electrocardiogram could be used for determining fetal heart rate, fetal electrocardiogram electrophysiological information, and uterine contraction activity.

    Catheter coatings have the potential to decrease infection and thrombosis in patients with chronic dialysis catheters. We report our midterm experience with a heparin-coated dialysis catheter. This retrospective, case-control study was approved by our Institutional Review Board. A total of 88 tunneled dialysis catheters were inserted over a 13-month period via the internal jugular vein. Thirty-eight uncoated split-tip catheters and 50 heparin-coated catheters were inserted. Primary catheter patency was compared between the two groups using the log rank test, with infection and/or thrombosis considered as catheter failures. Dialysis parameters during the first and last dialysis sessions, including pump speed, actual blood flow, and arterial port pressures, were compared using unpaired t-tests. Primary patency of the uncoated catheters was 86.0 +/- 6.5% at 30 days and 76.1 +/- 8.9% at 90 days. Primary patency of heparin-coated catheters was 92.0 +/- 6.2% at 30 days and 81.6 +/- 8.0% at 90 days (p = 0.87, log rank test). Infection requiring catheter removal occurred in four patients with uncoated catheters and two patients with heparin-coated catheters (p = 0.23). Catheter thrombosis requiring catheter replacement or thrombolysis occurred in one patient with an uncoated catheter and two patients with heparin-coated catheters (p = 0.9). No differences in catheter function during hemodialysis were seen between the two groups. In conclusion, the heparin-coated catheter did not show a significantly longer patency compared to the uncoated catheter. The flow characteristics of this device were comparable to those of the conventional uncoated catheter. A demonstrable benefit of the heparin-coated catheter in randomized trials is needed before a recommendation for routine implementation can be made.

    The purpose of this study was to evaluate the usefulness of a multifunctional gastrointestinal coil catheter for stent placement in 98 patients with colorectal strictures. The catheter was used in 98 consecutive patients for stent placement in the rectum (n = 24), recto-sigmoid (n = 13), sigmoid (n = 38), descending (n = 6), transverse (n = 11), splenic flexure (n = 3), hepatic flexure (n = 2), and ascending (n = 1) colon. The catheter was made of a stainless steel coil (1.3 mm in inner diameter), a 0.4-mm nitinol wire, a polyolefin tube, and a hemostasis valve. Usefulness of the catheter was evaluated depending on whether the catheter could pass a stricture over a guide wire and whether measurement of the stricture length was possible. The passage of the catheter over a guide wire beyond the stricture was technically successful and well tolerated in 93 (94.9%) of 98 patients. In the failed five patients, it was not possible to negotiate the guide wire due to presence of nearly complete small bowel obstruction. The average length of stricture was 6.15 cm (range, 3 cm to 20 cm) in patients with the colorectal stricture. There were no procedure-related complications. In conclusion, the multifunctional coil catheter seems to be useful in colorectal stent placement. (orig.)

    Percutaneous catheter drainage has been reported to be an effective method in the management of selected patients with abscess and fluid collection. Its high success rate and relatively low complications make the procedure an alternative to surgery in the individual cases. During past two years percutaneous catheter drainage in 25 patients with intraabdominal abscesses and fluid collection was performed at the Department of Radiology, Yonsei University College of medicine. Here the technique and author's results were summarized. 1. The total 25 patients who had percutaneous catheter drainage are 10 liver abscesses, 3 subphrenic, one subhepatic, 4 renal and perirenal, 2 pelvic, one psoas, one anterior pararenal fluid from acute pancreatitis, one pancreas pseudocyst and 2 malignant tumor necrosis. 2. The modified Seldinger technique used for all cases of abscess and fluid drainage under guidance of ultrasound scan. The used catheters were 10F. Pigtail and 14F. Malecot (Cook c/o) catheters. 3. The abscesses and fluid of 17 patients among 25 were cured by the percutaneous catheter drainage and 4 patients were clinically improved. The catheter drainage was failed in 2 patients and 3 complication were developed. 4. The success rate of this procedure was 91.3%, failure rate was 8.7% and complication rate was 12%.

    Full Text Available Insertion of central venous catheter is an accepted method for hemodynamic monitor-ring, drug and fluid administration, intravenous access, hemodialysis and applying cardiac pace-maker in hospitalized patients. This procedure can be associated with severe complications. The aim of this article is to provide a practical approach to prevent catheter malposition in states that the guide wire will not pass freely.During central venous insertion in internal jugular vein using modified seldinger technique, when after venous insertion, the passage of the guide wire shows difficulties and don’t pass freely, insertion of an intravenous cannula over the wire and re-insertion of the wire can help to prevent malposition of the wire and the catheter. Use of an intravenous cannula over the guide, in situations that the guide wire cannot pass freely among the needle inserted in internal jugular vein, and re-insertion of the guide can probably prevent or reduce the tissue or vascular trauma and the associated complica-tions. This simple maneuver can be helpful in difficult cases especially in cardiac surgery patients who receive high dose heparin and it is necessary to avoid traumatize-tion of carotid artery.

    We discuss how to use special Cosserat rod theory for deriving distributed-parameter static equilibrium equations of magnetic catheters. These medical devices are used for minimally-invasive diagnostic and therapeutic procedures and can be operated remotely or controlled by automated algorithms. The magnetic material can be lumped in rigid segments or distributed in flexible segments. The position vector of the cross-section centroid and quaternion representation of an orthonormal triad are selected as DOF. The strain energy for transversely isotropic, hyperelastic rods is augmented with the mechanical potential energy of the magnetic field and a penalty term to enforce the quaternion unity constraint. Numerical solution is found by 1D finite elements. Material properties of polymer tubes in extension, bending and twist are determined by mechanical and magnetic experiments. Software experiments with commercial FEM software indicate that the computational effort with the proposed method is at least one order of magnitude less than standard 3D FEM.

    PURPOSE To assess resistive heating of microwires used for remote catheter steering in interventional magnetic resonance imaging. To investigate the use of alumina to facilitate heat transfer to saline flowing in the catheter lumen. MATERIALS AND METHODS A microcoil was fabricated using a laser lathe onto polyimide-tipped or alumina-tipped endovascular catheters. In vitro testing was performed in a 1.5 T MR system using a vessel phantom, body RF coil, and steady state pulse sequence. Resistive heating was measured with water flowing over a polyimide tip catheter, or saline flowing through the lumen of an alumina-tip catheter. Preliminary in vivo testing in porcine common carotid arteries was conducted with normal blood flow or after arterial ligation when current was applied to an alumnia-tip catheter for up to 5 minutes. RESULTS After application of up to 1 W of DC power, clinically significant temperature increases were noted with the polyimide-tip catheter: 23°C/W at zero flow, 13°C/W at 0.28 cc/s, and 7.9°C/W at 1 cc/s. Using the alumina-tip catheter, the effluent temperature rise using the lowest flow rate (0.12 cc/s) was 2.3°C/W. In vivo testing demonstrated no thermal injury to vessel walls at normal and zero arterial flow. CONCLUSION Resistive heating in current carrying wire pairs can be dissipated by saline coolant flowing within the lumen of a catheter tip composed of material that facilitates heat transfer.

    Purpose: To determine the patency rates of and factors associated with increased risk of patency failure in patients with femoral vein tunneled hemodialysis catheters. Methods: All femoral tunneled catheter insertions from 1996 to 2006 were reviewed, during which time 123 catheters were inserted. Of these, 66 were exchanges. Patients with femoral catheter failure versus those with femoral catheter patency were compared. Confounding factors, such as demographic and procedural factors, were incorporated and assessed using univariate and multivariable Cox proportional hazards regression analyses. Results: Mean catheter primary patency failure time was 96.3 days (SE 17.9 days). Primary patency at 30, 60, 90, and 180 days was 53.8%, 45.4%, 32.1%, and 27.1% respectively. Crude rates of risk of catheter failure did not suggest a benefit for patients receiving catheters introduced from one side versus the other, but more cephalad location of catheter tip was associated with improved patency. Multivariate analysis showed that patients whose catheters were on the left side (p = 0.009), were of increasing age at the time of insertion (p = 0.002) and that those who had diabetes (p = 0.001) were at significantly greater risk of catheter failure. The catheter infection rate was 1.4/1000 catheter days. Conclusion: Patients who were of a more advanced age and had diabetes were at greater risk of femoral catheter failure, whereas those who received femoral catheters from the right side were less at risk of catheter failure.

    A cerebrospinal fluid shunt in the form of a ventricular catheter for controlling the condition of hydrocephalus by relieving the excessive cerebrospinal fluid pressure is described. A method for fabrication of the catheter and shunting the cerebral fluid from the cerebral ventricles to other areas of the body is also considered. Shunt flow failure occurs if the ventricle collapse due to improper valve function causing overdrainage. The ventricular catheter comprises a multiplicity of inlet microtubules. Each microtubule has both a large openings at its inlet end and a multiplicity of microscopic openings along its lateral surfaces.

  14. The impact of sodium citrate on dialysis catheter function and frequency of catheter-related bacteriemia and haemorrhage

    2009-10-01

    Full Text Available Vascular access is one of the most important problems of hemodialysis therapy. It is known that an arteriovenous fi sutla provides the best vascular access, but its creation is not always possible. Other solutions, such as the insertion of a central venous catheter, are then required. Adequate protection of such catheters by interdialytic fi ll with locking solution affects the frequency of hemodialysis-related complications. The most widespread catheter locking solution is heparin. Sodium citrate is being used more frequent recently. Available data indicate that hemorrhage is 11.9 times more frequent if the catheter locking solution is 5000 IU/ml heparin than if 4�0sodium citrate or 1000 IU/ml heparin is used. Other data indicate that the frequency of infection is statistically decreased when 30�0sodium citrate is used to fi ll the catheter instead of 5000 IU/ml heparin. Analogous data on 46.7�0sodium citrate are not consistent. It seems that the use of 4�0sodium citrate instead of 5000 IU/ml heparin does not decrease the frequency of infections. Numerous studies indicate that sodium citrate at various concentrations exerts a positive infl lence on catheter function. However, not all data are in accord. The spill of sodium citrate from the catheter to the systemic circulation is connected with a risk of adverse events. It may be dangerous if the citrate concentration is 46.7�20However, adequate fi lling of the catheter should prezent such events. Available data indicate that fi lling of the catheter with a solution of citrate of a concentration of no more than 30�0should be safe. Data on 46.7�0citrate are not conclusive, so precautions should be taken.

    Continuous brachial plexus nerve block catheters are commonly inserted for postoperative analgesia after upper extremity surgery. Modifications of the insertion technique have been described to improve the safety of placing an infraclavicular brachial plexus catheter. Rarely, these catheters may become damaged or entrapped, complicating their removal. We describe a case of infraclavicular brachial plexus catheter entrapment related to differences in arm positioning during catheter placement and removal. Written authorization to obtain, use, and disclose information and images was obtained from the patient.

    Central venous catheters (CVCs) are commonly used in children, and inadvertent arterial or extravascular cannulation is rare but has potentially serious complications. To identify the radiographic signs of arterial placement of CVCs. We retrospectively reviewed seven cases of arterially malpositioned CVCs on chest radiograph. These cases were identified through departmental quality-assurance mechanisms and external consultation. Comparison of arterial cases was made with 127 age-matched chest radiographs with CVCs in normal, expected venous location. On each anteroposterior (AP) radiograph we measured the distance of the catheter tip from the right lateral border of the thoracic spine, and the angle of the vertical portion of the catheter relative to the midline. On each lateral radiograph we measured the angle of the vertical portion of each catheter relative to the anterior border of the thoracic spine. When bilateral subclavian catheters were present, the catheter tips were described as crossed, overlapping or uncrossed. On AP radiographs, arterially placed CVCs were more curved to the left, with catheter tip positions located farther to the left of midline than normal venous CVCs. When bilateral, properly placed venous catheters were present, all catheters crossed at the level of the superior vena cava (SVC). When one of the bilateral catheters was in arterial position, neither of the catheters crossed or the inter-catheter crossover distance was exaggerated. On lateral radiographs, there was a marked anterior angulation of the vertical portion of the catheter (mean angle 37 ± 15 standard deviation [SD] in arterial catheters versus 5.9 ± 8.3 SD in normally placed venous catheters). Useful radiographic signs suggestive of unintentional arterial misplacement of vascular catheters include leftward curvature of the vertical portion of the catheter, left-side catheter tip position, lack of catheter crossover on the frontal radiograph, as well as exaggerated

  17. Dialysis Catheters and Their Common Complications: An Update

    2009-01-01

    Full Text Available Tunneled dialysis catheters (TDCs are associated with the highest rate of complications, morbidity, and mortality when compared to arteriovenous fistulas or grafts, and this relates to higher costs in their management. Over time, catheters are prone to higher rates of infection, thrombosis, and central venous stenosis, and, thereby, catheter dysfunction. Lower blood flow rates are a consequence of the dysfuncion. Despite efforts to reduce incident and prevalent rates of catheter use for dialysis by the National Kidney Foundation and Fistula First Initiative, they remain a common modality of hemodialysis. The management of common TDC-related complications is discussed, in addition to ways to reduce and prevent morbidity associated with their use.

    The development of new catheter and applicator technologies in recent years has significantly improved treatment accuracy, efficiency, and outcomes in brachytherapy. In this paper, we review these advances, focusing on the performance of catheter imaging and reconstruction techniques in brachytherapy procedures using magnetic resonance images and electromagnetic tracking. The accuracy of catheter reconstruction, imaging artifacts, and other notable properties of plastic and titanium applicators in gynecologic treatments are reviewed. The accuracy, noise performance, and limitations of electromagnetic tracking for catheter reconstruction are discussed. Several newly developed applicators for accelerated partial breast irradiation and gynecologic treatments are also reviewed. New hypofractionated high dose rate treatment schemes in prostate cancer and accelerated partial breast irradiation are presented.

    Interventional radiologists desire to improve their operating tools such as catheters. Active catheters in which the tip is moved using shape memory alloy actuators activated using the Joule effect present a promising approach for easier navigation in the small vessels. However, the increase in temperature caused by this Joule effect must be controlled in order to prevent damage to blood cells and tissues. This paper is devoted to the simulation and experimental validation of a fluid-thermal model of an active catheter prototype. Comparisons between computer-predicted and experimentally measured temperatures are presented for both experiments in air and water at 37°C. Good agreement between the computational and experimental results is found, demonstrating the validity of the developed computer model. These comparisons enable us to highlight some important issues in the modelling process and to determine the optimal current for the activation of the catheter.

    Opportunities for improvements in patient outcomes through applied continuous quality improvement (CQI) programs are endless and exciting. Improving vascular access outcomes has been a long-standing clinical problem for hemodialysis patients and the nephrology team. During the past few years there has been a dramatic increase in the use of dialysis catheters as permanent accesses for hemodialysis patients. All hemodialysis with dialysis catheters are at risk for catheter occlusion. An innovative, 2-year CQI program was developed, implemented, and designed to improve dialysis catheter patency rates with the use of urokinase. The CQI program resulted in a number of clinical outcomes that were beneficial to the patients and dialysis staff, and were cost-effective to the program.

    This paper presents the three dimensional kinematic modeling of a novel steerable robotic ablation catheter system. The catheter, embedded with a set of current-carrying micro-coils, is actuated by the magnetic forces generated by the magnetic field of the MRI scanner. This paper develops a 3D model of the MRI actuated steerable catheter system by using finite differences approach. For each finite segment, a quasi-static torque-deflection equilibrium equation is calculated using beam theory. By using the deflection displacements and torsion angles, the kinematic modeling of the catheter system is derived. The proposed models are evaluated by comparing the simulation results of the proposed model with the experimental results of a proof-of-concept prototype.

    In February 1995, a 56-year-old female was taken to the operating room for routine placement of a Hickman catheter. Her internist planned palliative chemotherapy for metastatic breast cancer. Using the Seldinger technique, the right subclavian vein was entered and a Hickman catheter was placed. Shortly after extubation and arrival in the postoperative recovery unit, the patient had respiratory and cardiac arrest. Resuscitative efforts, including chest tube placement and pericardiocentesis, were unsuccessful. Autopsy findings included perforation of the superior vena cava, with extension of the catheter in the pericardial sac and associated effusion. Despite the low reported incidence of perforation during placement of central venous catheters, we recommend confirmation of placement by fluoroscopy and instillation of radiopaque dye because of the high mortality associated with this complication.

    Totally Implantable Central Venous Access Devices (Intraports) are commonly used in cancer patients to administer chemotherapy or parenteral nutrition. These devices are placed by Seldinger technique. We report an unusual case of intraport catheter rupture before the use of the device. The ruptured part of the catheter migrated into the left pulmonary vein via right ventricle. The ruptured part was removed by means of interventional radiology before causing any problems to the patient. All the reported ruptures of port catheters refer to port devices that had been used to administer chemotherapy, fluids, or parenteral nutrition. The unique feature of this case is that the catheter had not been used at all. It is of great interest also the removal of the broken part from the pulmonary vein.

  7. Anatomical Consideration in Catheter Ablation of Idiopathic Ventricular Arrhythmias.

    2016-01-01

    Idiopathic ventricular arrhythmias (VAs) are ventricular tachycardias (VTs) or premature ventricular contractions (PVCs) with a mechanism that is not related to myocardial scar. The sites of successful catheter ablation of idiopathic VA origins have been progressively elucidated and include both the endocardium and, less commonly, the epicardium. Idiopathic VAs usually originate from specific anatomical structures such as the ventricular outflow tracts, aortic root, atrioventricular (AV) annuli, papillary muscles, Purkinje network and so on, and exhibit characteristic electrocardiograms based on their anatomical background. Catheter ablation of idiopathic VAs is usually safe and highly successful, but can sometimes be challenging because of the anatomical obstacles such as the coronary arteries, epicardial fat pads, intramural and epicardial origins, AV conduction system and so on. Therefore, understanding the relevant anatomy is important to achieve a safe and successful catheter ablation of idiopathic VAs. This review describes the anatomical consideration in the catheter ablation of idiopathic VAs.

    Purpose: To determine whether alternative high dose rate prostate brachytherapy catheter patterns can result in similar or improved dose distributions while providing better access and reducing trauma. Materials and Methods: Standard prostate cancer high dose rate brachytherapy uses a regular grid of parallel needle positions to guide the catheter insertion. This geometry does not easily allow the physician to avoid piercing the critical structures near the penile bulb nor does it provide position flexibility in the case of pubic arch interference. This study used CT datasets with 3 mm slice spacing from ten previously treated patients and digitized new catheters following three hypothetical catheter patterns: conical, bi-conical, and fireworks. The conical patterns were used to accommodate a robotic delivery using a single entry point. The bi-conical and fireworks patterns were specifically designed to avoid the critical structures near the penile bulb. For each catheter distribution, a plan was optimized with the inverse planning algorithm, IPSA, and compared with the plan used for treatment. Irrelevant of catheter geometry, a plan must fulfill the RTOG-0321 dose criteria for target dose coverage (V{sub 100}{sup Prostate}>90%) and organ-at-risk dose sparing (V{sub 75}{sup Bladder}<1 cc, V{sub 75}{sup Rectum}<1 cc, V{sub 125}{sup Urethra}<<1 cc). Results: The three nonstandard catheter patterns used 16 nonparallel, straight divergent catheters, with entry points in the perineum. Thirty plans from ten patients with prostate sizes ranging from 26 to 89 cc were optimized. All nonstandard patterns fulfilled the RTOG criteria when the clinical plan did. In some cases, the dose distribution was improved by better sparing the organs-at-risk. Conclusion: Alternative catheter patterns can provide the physician with additional ways to treat patients previously considered unsuited for brachytherapy treatment (pubic arch interference) and facilitate robotic guidance of

  14. [Anesthetic consideration in patients undergoing catheter ablation for atrial fibrillation].

    Science.gov (United States)

    Oda, Toshiyuki; Takahama, Yutaka

    2012-11-01

    This chapter describes anesthetic consideration in patients undergoing catheter ablation for atrial fibrillation (AF) based on electrophysiologic or pharmacological aspects. In the 2011 guidelines of the Japanese Circulation Society for non-pharmacotherapy of cardiac arrhythmias, catheter ablation is recommended as Class I therapeutic modality for the patients with drug-refractory paroxysmal AF. Catheter ablation of AF is an invasive and long-lasting procedure necessitating sedation during treatment. However, in the most of the patients, sedation or anesthesia is possibly performed by cardiologists using propofol, midazolam or dexmedetomidine. Deep sedation accompanies a high risk of ventilatory or circulatory derangement. Furthermore, life-threatening complications, such as cerebral infarction or cardiac tamponade, can occur during ablation. Patients with AF are increasing in number as a trend in the aging society, resulting in an increase in catheter ablation in high risk patients. To accomplish safe anesthetic management of the patients for catheter ablations, anesthesiologists are required to have fundamental knowledge and skill in the performance of the catheter ablation.

  15. Misplaced central venous catheters: applied anatomy and practical management.

    2013-03-01

    Large numbers of central venous catheters (CVCs) are placed each year and misplacement occurs frequently. This review outlines the normal and abnormal anatomy of the central veins in relation to the placement of CVCs. An understanding of normal and variant anatomy enables identification of congenital and acquired abnormalities. Embryological variations such as a persistent left-sided superior vena cava are often diagnosed incidentally only after placement of a CVC, which is seen to take an abnormal course on X-ray. Acquired abnormalities such as stenosis or thrombosis of the central veins can be problematic and can present as a failure to pass a guidewire or catheter or complications after such attempts. Catheters can also be misplaced outside veins in a patient with otherwise normal anatomy with potentially disastrous consequences. We discuss the possible management options for these patients including the various imaging techniques used to verify correct or incorrect catheter placement and the limitations of each. If the course of a misplaced catheter can be correctly identified as not lying within a vulnerable structure then it can be safely removed. If the misplaced catheter is lying within or traversing large and incompressible arteries or veins, it should not be removed before consideration of what is likely to happen when it is removed. Advice and further imaging should be sought, typically in conjunction with interventional radiology or vascular surgery. With regard to misplaced CVCs, in the short term, a useful aide memoir is: 'if in doubt, don't take it out'.

    To evaluate a recently developed technique to place a medium-duration (weeks to months) central venous access. Within three-year period, 635 patients were referred to interventional radiology suite for placement of peripherally inserted central catheter (PICC). Contrast medium was injected into the peripheral intravenous line and a puncture was made into the opacified vein near the junction of the middle and upper thirds of the upper arm, either the brachial or basilic vein under fluoroscopic guidance. A 5.5-French peel-away sheath was inserted into the vein and a 5-French silicone catheter was introduced with its distal tip to the junction of the right atrium and superior vena cava. Catheter placement was successful in all patients unless there was a central venous obstruction. Catheters were maintained from 2 days to 5 months with a mean of 3 weeks. Complications included infection requiring removal of the PICC in 16 patients (2.5%), acute thrombosis of the subclavian vein in 3 (0.5%). Occluded catheters in 4 patients were easily cleared with urokinase in place. The PICC system is an excellent option for medium-duration central venous access. Patients were able to carry on normal activities with the catheters in place.

    Since the advent of rehabilitation engineering new advances have been made that have revolutionized condom catheter drainage systems (CCDS). An innovative CCDS has been designed that ensures unobstructed urine flow. Its condom catheter has several unique design features. It has a double row of convolutions near the catheter tip that prevent kinking and twisting so that the pathway remains open. The condom catheter features a unique inner flap that fits snugly on the glans to prevent backflow of urine on the shaft. This condom catheter is connected to a vented leg bag that eliminates the development of a partial vacuum in the connecting tube. This vacuum can create siphoning, which in turn interferes with urine flow into the leg bag. In addition, a new rechargeable battery-operated clipper has been developed that makes nick-free hair removal from the genitals exceptionally easy. This atraumatic hair removal eliminates the pubic hair that becomes trapped under the condom catheter. The clinical impact of these new advances in CCDS requires further investigation.

    In cardiology, a vulnerable plaque is considered to be a key subject because it is strongly related to atherosclerosis and acute myocardial infarction. Because conventional intravascular imaging devices exhibit several limitations with regard to vulnerable plaque detection, the need for an effective lipid imaging modality has been continuously suggested. Photoacoustic (PA) imaging is a medical imaging technique with a high level of ultrasound (US) resolution and strong optical contrast. In this study, we successfully developed an integrated intravascular photoacoustic/ultrasound (IV-PAUS) imaging system with a catheter diameter of 1.2 mm for lipid-rich atherosclerosis imaging. An Nd:YAG pulsed laser with an excitation wavelength of 1064 nm was utilized. IV-PAUS offers 5-mm depth penetration and axial and lateral PA imaging resolutions of 94 μm and 203 μm, respectively, as determined by imaging a 6-μm carbon fiber. We initially obtained 3-dimensional (3D) co-registered PA/US images of metal stents. Subsequently, we successfully obtained 3D coregistered PA/US ex vivo images using an iliac artery from a rabbit atherosclerosis model. Accordingly, lipid-rich plaques were sufficiently differentiated from normal tissue in the ex vivo experiment. We validated these findings histologically to confirm the lipid content.

    An adductor canal catheter may facilitate early ambulation after total knee arthroplasty, but there is concern over preoperative placement since intraoperative migration of catheters may occur from surgical manipulation and result in ineffective analgesia. We hypothesized that catheter type and subcutaneous tunneling may influence tip migration for preoperatively inserted adductor canal catheters. In a male unembalmed human cadaver, 20 catheter insertion trials were divided randomly into one of four groups: flexible epidural catheter either tunneled or not tunneled; or rigid stimulating catheter either tunneled or not tunneled. Intraoperative patient manipulation was simulated by five range-of-motion exercises of the knee. Distance and length measurements were performed by a blinded regional anesthesiologist. Changes in catheter tip to nerve distance (p = 0.225) and length of catheter within the adductor canal (p = 0.467) were not different between the four groups. Two of five non-tunneled stimulating catheters (40 %) were dislodged compared to 0/5 in all other groups (p = 0.187). A cadaver model may be useful for assessing migration of regional anesthesia catheters; catheter type and subcutaneous tunneling may not affect migration of adductor canal catheters based on this preliminary study. However, future studies involving a larger sample size, actual patients, and other catheter types are warranted.

    Full Text Available Hemodialysis (HD catheters are commonly used as temporary vascular access in patients with kidney failure who require immediate HD. The use of these catheters is limited by complications such as infections, thrombosis resulting in poor blood flow. We studied the complications and outcomes of nontunneled catheters used for vascular access in our dialysis unit. The records of all patients, with renal failure who were dialyzed over a two-year period and had a double lumen nontunneled catheter inserted, were retrieved. Catheter insertion was carried out under ultrasound guidance using the modified Seldinger technique. The demographic data of patients, etiology of chronic kidney disease, and complications and outcomes of these catheters were noted. Fifty-four patients with mean age 43.7 ± 15.8 years had 69 catheters inserted for a cumulative total of 4047 catheter-days. The mean catheter patency was 36.4 ± 37.2 days (range: 1-173 days. Thrombosis occluding the catheters was the most common complication and occurred in 58% of catheters leading to catheter malfunction, followed by infections in18.8% of catheters. During follow-up, 30 (43.5% catheters were removed, 14 (20.3% due to catheter malfunction, eight (11.6% due to infection, five (7.2% elective removal, and three (4.3% due to damage. Thrombotic occlusion of catheters was a major limiting factor to the survival of HD catheters. Improvement in catheter patency can be achieved with more potent lock solutions.

    Objective To compare the clinical outcomes of open surgical peritoneal dialysiscatheter(PDC) insertion with guide wireand the outcomesof PDC insertion without guide wire.Methods Data of the patients receiving open surgical Tenkchoff straight catheter insertion in our department from January 2005 to January 2011 were retrospectively analyzed.The 117 patients in whom PDC insertion was conducted with the guidance of guide wire were enrolled into group A, and the 121 cases receiving PDC insertion without guide wire wereenrolled into group B.The incidences of post-operative complications (catheter obstruction,catheter displacement, bloody dialysate, and dialysate leakage), catheter survival, and patientsurvival rates were compared between the 2 groups.Results The baseline characteristics (gender, age, body mass index, prothrombin time,activated partialthromboplastin time,platelet count,serum creatinine,follow-up time,primarydiseases, and outcomes) of the 2 groups were comparable (allP>0.05). In post-operativecomplications, only the incidence of early bloody dialysate showed significant difference, being16.2% in groupA and 7.4% in group B (P=0.04). Catheter and patient survival rates werenot significantly different between the two groups. Overweight patientsshowed a higherincidence of catheter obstruction compared with normal weight patients [16.0% (4/25) vs. 3.3% (7/213),P=0.02], but no differencesin post-operative complications werefound among overweight patientsbetween the 2 groups.Conclusions Open surgical Tenkchoff straightcatheterinsertion without guide wire does not lead to higher risk of post-operative complications and catheter removal. It may be an alternativeoption when guide wire is not available.

    Full Text Available Background/Aim. Central venous catheters (CVC are at the crucial importance, particulary in the intensive therapy units. In order to handle a CVC safely, nursing students need to acquire theoretical and practical knowledge during the course of their studies. The aim of the study was to establish theoretical knowledge of nursing students about the procedures of nurses in placing and removing a central venous catheter (CVC, dressing the catheter entry point, the reasons for measuring central venous pressure (CVP, possible complications and risk factors for developing infections related to CVC. Methods. The questionnaire developed specifically for this cross-sectionl study was handed out to 87 full-time students and 57 part-time students. Results. The results show that all the surveyed nursing students know why chest radiography is carried out when inserting a catheter, have relatively good knowledge of CVC insertion points, procedures carried out in case of a suspected catheter sepsis and complications and risk factors for the development of infections related to CVC. However, the study show that the majority of students have insufficient knowledge of the procedures accompanying insertion of a catheter, signs that indicate correct functioning of CVC, frequency of flushing a catheter when it is not in use and the reasons for introducing an implanted CVC. Conclusion. Based on the results of the study it can be concluded that the second-year nursing students have insufficient knowledge of CVC. In order to correctly and safely handle a CVC, good theoretical knowledge and relevant practical experience are needed. The authors therefore believe that, in future, the classes should be organized in smaller groups with step-by-step demonstrations of individual procedures in handling a CVC, and the students encouraged to learn as actively as possible.

    Helium pulsed balloons are integral components of several cardiovascular devices, including intraaortic balloon pumps (IABP) and a novel intravenous respiratory support catheter. Effective use of these devices clinically requires full inflation and deflation of the balloon, and improper operating conditions that lead to balloon under-inflation can potentially reduce respiratory or cardiac support provided to the patient. The goal of the present study was to extend basic spirographic techniques to develop a system to dynamically measure balloon volumes suitable for use in rapidly pulsating balloon catheters. The dynamic balloon volume sensor system (DBVSS) developed here used hot wire anemometry to measure helium flow in the drive line from console to catheter and integrated the flow to determine the volume delivered in each balloon pulsation. An important component of the DBVSS was an algorithm to automatically detect and adjust flow signals and measured balloon volumes in the presence of gas composition changes that arise from helium leaks occurring in these systems. The DBVSS was capable of measuring balloon volumes within 5-10% of actual balloon volumes over a broad range of operating conditions relevant to IABP and the respiratory support catheter. This includes variations in helium concentration from 70-100%, pulsation frequencies from 120-480 beats per minute, and simulated clinical conditions of reduced balloon filling caused by constricted vessels, increased driveline, or catheter resistance.

    AIM: To study the incidence, bacterial spectrum and drug sensitivity of catheter-related infection (CRI) in gastrointestinal fistula patients.METHODS: A total of 216 patients with gastrointestinal fistulae during January 1998 to April 2001 were studied retrospectively. Two hundred and sixteen catheters of the 358 central venous catheters used in 216 gastrointestinal fistula patients were sent for microbiology analysis.RESULTS: Ninety-five bacteria were cultivated in 88catheters (24.6%). There were 54 Gram-negative bacteria (56.8%), 35 Gram-positive bacteria (36.8%), and 6 fungi (6.4%). During the treatment of CRI, 20 patients changed to use antibiotics or antifungal, and all patients were cured.The mean time of catheters used was 16.9±13.0 d.CONCLUSION: CRI is still the common complication during total parenteral nutrition (TPN) treatment in patients with gastrointestinal fistulae, and Gram-negative bacteria are the main pathogens, and bacterial translocation is considered the common reason for CRI.

    Full Text Available In recent years an increasing incidence and prevalence of oncological diseases is observed, with a consequent increase in chemotherapies. In order to avoid repeated venipuncture of patients and toxicity in small veins during different cycles of treatment, devices that provide a permanent central venous access are used. The aim of this study was to evaluate the success and safety of port a cath devices inserted by surgery residents. A consecutive case series of patients in whom Port-a-CathTM catheter was placed by residents of surgery in the period from March 2009 to January 2014 were included. A total of 358 Port-a-CathTM catheters were inserted. Average age 58.7 years (16-88. Females 53.1%. Chemotherapy treatment for solid neoplasias (74.8% and for hematological diseases (25.2%. SThe different venous accesses were: Subclavian (67.6%, Cephalic (27.4%, external jugular (3.3%, internal jugular (1.7%. The morbidity rate was 5.3%, twelve patients with catheter-associated infection requiring the removal of it, 3 venous thrombosis with subsequent replacement of the catheter and 4 patients required pleural drainage. Port-a-CathTM catheter placement by residents is a safe and effective procedure for the administration of chemotherapy

  16. Heparin Leakage in Central Venous Catheters by Hemodynamic Transport

    2014-11-01

    Central venous catheters (CVCs), placed in the superior vena cava for hemodialysis, are routinely filled with heparin, an anticoagulant, while not in use to maintain patency and prevent thrombus formation at the catheter tip. However, the heparin-lock procedure places the patient at risk for systemic bleeding incidences, as heparin is known to leak into the blood stream. We propose that the driving mechanism behind heparin leakage is advective-diffusive transport due to the pulsatile blood flow surrounding the catheter tip. This novel hypothesis is based on Planar Laser Induced Fluorescence (PLIF) measurements of heparin transport from a CVC placed inside an in vitro pulsatile flow loop and validated with CFD simulations. The results show an initial, fast (catheter lumen, where concentration is still high, that is insufficient at replenishing the lost heparin at the tip. These results, which estimate leakage rates consistent with published in vivo data, predict that the concentration of heparin at the catheter tip is effectively zero for the majority of the interdialytic phase, rendering the heparin lock ineffective.

    Central line-associated bloodstream infections (CLABSIs) are not easily treated, and many catheters (e.g., hemodialysis catheters) are not easily replaced. Biofilms (the source of infection) on catheter surfaces are notoriously difficult to eradicate. We have recently demonstrated that modest elevations of temperature lead to increased staphylococcal susceptibility to vancomycin and significantly soften the biofilm matrix. In this study, using a combination of microbiological, computational, and experimental studies, we demonstrate the efficacy, feasibility, and safety of using heat as an adjuvant treatment for infected hemodialysis catheters. Specifically, we show that treating with heat in the presence of antibiotics led to additive killing of Staphylococcus epidermidis with similar trends seen for Staphylococcus aureus and Klebsiella pneumoniae. The magnitude of temperature elevation required is relatively modest (45-50°C) and similar to that used as an adjuvant to traditional cancer therapy. Using a custom-designed benchtop model of a hemodialysis catheter, positioned with tip in the human vena cava as well as computational fluid dynamic simulations, we demonstrate that these temperature elevations are likely achievable in situ with minimal increased in overall blood temperature.

  18. Epidural fibrosis after permanent catheter insertion and infusion.

    1995-11-01

    Forty-six permanent epidural catheters and life-port units were implanted in 43 patients with severe, recurrent low back pain who had been considered not to be candidates for surgical intervention and in whom other therapeutic modalities had failed. Eight cases developed epidural fibrosis (EF). For analgesia, patients received either infusions with preservative-free solutions of fentanyl and bupivacaine or daily boluses of morphine and bupivacaine. Catheters remained from 75 days to 433 days. Signs of EF appeared from 21 days to 320 days after implantation. Pain at injection or resistance to injection were initial manifestations of EF, followed by poor, and eventually, nil analgesic effect. The epidural catheters were made of either polyamide, silicone, or polyurethane. Epidurograms revealed encapsulation, narrowing, and loculation of epidural space with gradually reduced spread of the contrast material. The occurrence of EF limits the permanency of implanted epidural catheters. The infusate does not cause this complication, which appears to be a foreign body reaction due to the presence of the catheter in the epidural space.

    Full Text Available Introduction: The PICC (peripherally inserted central catheter is a long flexible catheter which is inserted through a peripheral vein, progresses through a needle introducer until the final portion of the vena cava, acquiring characteristics of a central catheter. Objective: To point out the main theoretical and scientific ideas that demonstrate the reliability, competence and ability of nurses to perform the PICC. Methodology: Systematic review of articles, which were found by searching the database scientific journals and bibliographies area. Results: The success of integration depends on the patient assessment and choice of venous access where the catheter will be positioned, and its tip should be in the middle third of the superior vena cava, or the middle third of the inferior vena cava. In neonates, which are used more frequently, proper positioning of the catheter is through nursing care in making the dressing, and the first 24 hours it should be compressive. Ideally, the PICC remains in the vein for periods longer than seven days or until the end of treatment, thus decreasing invasive procedures. Conclusion: According to the Federal Board of Nursing (COFEN, it is lawful for the insertion of PICC nurses, provided it has undergone professional training.

    Full Text Available Objectives. To compare the efficacy and safety of intravaginal misoprostol with transcervical Foley catheter for labour induction. Material and Methods. One hundred and four women with term gestation, with Bishop score < 4, and with various indications for labour induction were randomly divided into two groups. In Group I, 25 μg of misoprostol tablet was placed intravaginally, 4 hourly up to maximum 6 doses. In Group II, Foley catheter 16F was placed through the internal os of the cervix under aseptic condition and then inflated with 50 cc of sterile saline. Statistical analysis was done using SPSS software. Results. The induction to delivery interval was 14.03 ± 7.61 hours versus 18.40 ± 8.02 hours (p<0.01. The rate of vaginal delivery was 76.7% versus 56.8% in misoprostol and transcervical Foley catheter group, respectively. Uterine hyperstimulation was more common with misoprostol. Neonatal outcome was similar in both the groups. Conclusion. Intravaginal misoprostol is associated with a shorter induction to delivery interval as compared to Foley’s catheter and it increases the rate of vaginal delivery in cases of unripe cervix at term. Transcervical Foley catheter is associated with a lower incidence of uterine hyperstimulation during labour.

    To evaluate the feasibility that a dilated right external jugular vein (EJV) could be a primary venous access site for large bore hemodialysis catheter placement. Between January 2008 and April 2009, a total of 173 hemodialysis catheters (14.5 F) were placed. Among them, we evaluated the clinical data of 42 patients who underwent placement through a dilated right EJV. We evaluated technical success, duration of catheterization in days, and the presence of complications. Technical success was achieved for 41 patients (98%). Catheter placement was unsuccessful in one patient due to narrowing of the EJV. The catheter dwell time ranged between 14 and 305 days (mean; 76 days, total catheter days: 3,111 days). A total of 26 hemodialysis catheters were removed due to complications (n=2) and termination of hemodialysis via the hemodialysis catheter (n=24). There was air embolization (n=1) and catheter kinking (n=3) during procedures and catheter related infections (n=2) during the follow-up period. The incidence of catheter related infection was 0.06 per 100 catheter days. No cases of catheter malfunction or symptomatic venous thrombosis were observed. We suggest that a dilated right EJV could be considered as a preferred primary route for hemodialysis catheter placement with easy access

    To assess the outcome of tunneled central venous catheter placement via the right internal jugular vein. Between June 2001 and May 2002, 670 consecutive Hickman catheters were placed in 654 patients via the right internal jugular vein. The procedural complications arising and follow-up data obtained from May to July 2002 were evaluated. The technical success rate for catheter placement was 99.9% (669/670). Procedural complications were limited to eight cases (1.2%), including three pneumothoraces, one early migration of the catheter, one clinically unimportant air embolism, one catheter injury, one catheter kinking and one primary malpositioning in the azygos vein. Catheter dwelling time ranged from 1 to 407 (mean 107.1) days. During the follow-up period, 416 catheter were removed for various reasons: treatment had ended (n=334), patients declined treatment or their drug regimen was changed (n=16), late complications arose (n=53), or other circumstances intervened (n=13). Late complications included 44 cases of catheter-related infection (6.6%), five of catheter migration (0.7%), two of catheter occlusion (0.3%), one of thrombophlebitis (0.15%), and one of catheter-related right atrial thrombosis (0.15%). Only one instance of symptomatic venous thrombosis or stenosis was noted, namely the one case of thrombophlebitis. Because the incidence of subsequent symptomatic venous thrombosis or stenosis is lower, the preferred route for tunneled central venous catheter placement is the right internal jugular vein.

    There is lack of adequate data on comparison of outcomes between percutaneously placed peritoneal dialysis (PD) catheters inserted by nephrologists and PD catheters placed by surgeons. The aim of this study is to retrospectively analyze the outcomes of PD catheters inserted by surgeons (by open surgical or laparoscopic technique) and compare them with those inserted by nephrologists among ESRD patients who underwent elective PD catheter insertions between January 2009 and December 2012. The primary outcome measure was the proportion of catheters removed because of primary nonfunction. The secondary outcome measures were catheter survival, patient survival, and incidence of complications of catheter insertion. A total of 143 PD catheter insertions (88 by surgeons and 55 by nephrologists) performed in 132 patients were considered for the analysis. The primary nonfunction rate of PD catheter insertions in both groups was comparable (18.2% and 7.3%, P = 0.08). Break-in period was shorter in Group N (p = <0.001). No differences were noted in patient or catheter survival. Percutaneously placed PD catheters performed by nephrologists have comparable outcomes with surgically placed PD catheters among selected cases and have the advantage of lower costs, avoidance of operation theater scheduling issues, smaller incision length, and shorter break-in period. Therefore, more nephrologists should acquire the expertise on percutaneous PD catheter placement as it leads to lesser waiting times and better utilization of PD. PMID:27512299

    Biofilm development in urinary tract catheters is an often underestimated problem. However, this form of infection leads to high mortality rates and causes significant costs in health care. Therefore, it is important to analyze these biofilms and establish avoiding strategies. In this study a continuous flow-through system for the cultivation of biofilms under catheter-associated urinary tract infection conditions was established and validated. The in vitro urinary tract catheter system implies the composition of urine (artificial urine medium), the mean volume of urine of adults (1 mL min(-1)), the frequently used silicone catheter (foley silicon catheter) as well as the infection with uropathogenic microorganisms like Pseudomonas aeruginosa. Three clinical isolates from urine of catheterized patients were chosen due to their ability to form biofilms, their mobility and their cell surface hydrophobicity. As reference strain P. aeruginosa PA14 has been used. Characteristic parameters as biofilm thickness, specific biofilm growth rate and substrate consumption were observed. Biofilm thicknesses varied from 105±16 μm up to 246±67 μm for the different isolates. The specific biofilm growth rate could be determined with a non invasive optical biomass sensor. This sensor allows online monitoring of the biofilm growth in the progress of the cultivation.

    The fracture of a central venous catheter is a rare but potentially serious complication. Moreover, removal of the broken catheter pieces is considerably challenging, especially for premature infants. We report 3 case studies of the percutaneous transcatheter retrieval of broken catheter parts in 3 premature infants. We confirmed the location of the catheter fragments via a DSA venogram with diluted contrast media. Using the minimum amount of contrast, and extreme caution, we made certain no contrast-induced nephrotoxicity of air embolism occurred during catheter manipulation. In addition, when the broken fragment was curled or attached to the cardiac wall, we used a hook-shaped catheter to facilitate the capturing of the catheter with a loopsnare. This report demonstrates the feasibility of removing a retained catheter fragment in a premature infant using a percutaneous transcatheter approach.

    Dual-lumen haemodiafiltration catheters enable continuous renal replacement therapy in the critically ill and are often co-located with central venous catheters used to infuse drugs. The extent to which infusions are immediately aspirated by an adjacent haemodiafiltration catheter remains unknown. A bench model was constructed to evaluate this effect. A central venous catheter and a haemodiafiltration catheter were inserted into a simulated central vein and flow generated using centrifugal pumps within the simulated vein and haemodiafiltration circuit. Ink was used as a visual tracer and creatinine solution as a quantifiable tracer. Tracers were completely aspirated by the haemodiafiltration catheter unless the infusion was at least 1 cm downstream to the arterial port. No tracer was aspirated from catheters infusing at least 2 cm downstream. Orientation of side ports did not affect tracer elimination. Co-location of central venous and haemodiafiltration catheters may lead to complete aspiration of infusions into the haemodiafilter with resultant drug under-dosing.

    To evaluate efficacy and the safety of percutaneous catheter drainage in patients with pneumothorax that is difficult to treat with closed thoracotomy. We retrospectively reviewed effectiveness of percutaneous catheter drainage (PCD) in 10 patients with pneumothorax. The catheter was inserted under fluoroscopic guidance. Seven patients had spontaneous pneumothorax caused by tuberculosis (n =4), reptured bullae (n = 2), and histiocytosis-X (n = 1). Three patients had iatrogenic pneumothorax caused by trauma (n = 1) and surgery (n = 2). All procedures were performed by modified Seldinger's method by using 8F-20F catheter. All catheter were inserted successfully. In 9 of 10 patients, the procedure was curative without further therapy. Duration of catheter insertion ranged from 1 day to 26 days. In the remaining 1 patient in whom multiple pneumothorax occurred after operation, catheter insertion was performed twice. Percutaneous catheter drainage under fluoroscopic guidance is effective and safe procedure for treatment of pneumothorax in patients with failed closed thoracotomy.

    To evaluate the safety of transgression of the bowel during intraperitoneal percutaneous catheter placement in an animal model. Eight 8-F straight catheters were percutaneously inserted into the small and large bowel of eight rabbits. In four animals, the catheters were left in place until autopsy, whereas in the remaining four, the catheters were withdrawn five days after insertion. Autopsy was performed in all animals ten days after catheter placement, and gross and microscopic examination was carried out. Transgressing the bowel during intraperitoneal percutaneous catheter placement did not contribute to any clinically significant complications. At autopsy, there was no bowel leakage, peritonitis, or abscess, although peritoneal adhesions were found around the catheter tract. Although further study is warranted, our study with an animal model indicated that transgression of the intestine during percutaneous placement of an intraabdominal catheter did not produce significant complications.

    The supraclavicular fossa ultrasound view can be useful for central venous catheter (CVC) placement. Venipuncture of the internal jugular veins (IJV) or subclavian veins is performed with a micro-convex ultrasound probe, using a neonatal abdominal preset with a probe frequency of 10 Mhz at a depth of 10-12 cm. Following insertion of the guidewire into the vein, the probe is shifted to the right supraclavicular fossa to obtain a view of the superior vena cava (SVC), right pulmonary artery and ascending aorta. Under real-time ultrasound view, the guidewire and its J-tip is visualized and pushed forward to the lower SVC. Insertion depth is read from guidewire marks using central venous catheter. CVC is then inserted following skin and venous dilation. The supraclavicular fossa view is most suitable for right IJV CVC insertion. If other insertion sites are chosen the right supraclavicular fossa should be within the sterile field. Scanning of the IJVs, brachiocephalic veins and SVC can reveal significant thrombosis before venipuncture. Misplaced CVCs can be corrected with a change over guidewire technique under real-time ultrasound guidance. In conjunction with a diagnostic lung ultrasound scan, this technique has a potential to replace chest radiograph for confirmation of CVC tip position and exclusion of pneumothorax. Moreover, this view is of advantage in patients with a non-p-wave cardiac rhythm were an intra-cardiac electrocardiography (ECG) is not feasible for CVC tip position confirmation. Limitations of the method are lack of availability of a micro-convex probe and the need for training.

    Despite the level of skill of the operator and the use of ultrasound guidance, central venous catheter (CVC) placement can result in CVC malpositioning, an unintended placement of the catheter tip in an inadequate vessel. CVC malpositioning is not a complication of central line insertion; however, undiagnosed CVC malpositioning can be associated with significant morbidity and mortality. The objectives of this review were to describe factors associated with intravascular malpositioning of CVCs inserted via the neck and chest and to offer ways of preventing, identifying, and correcting such malpositioning. A literature search of PubMed, Cochrane Library, and MD Consult was performed in June 2014. By searching for "Central line malposition" and then for "Central venous catheters intravascular malposition," we found 178 articles written in English. Of those, we found that 39 were relevant to our objectives and included them in our review. According to those articles, intravascular CVC malpositioning is associated with the presence of congenital and acquired anatomical variants, catheter insertion in left thoracic venous system, inappropriate bevel orientation upon needle insertion, and patient's body habitus variants. Although plain chest radiography is the standard imaging modality for confirming catheter tip location, signs and symptoms of CVC malpositioning even in presence of normal or inconclusive conventional radiography findings should prompt the use of additional diagnostic methods to confirm or rule out CVC malpositioning. With very few exceptions, the recommendation in cases of intravascular CVC malpositioning is to remove and relocate the catheter. Knowing the mechanisms of CVC malpositioning and how to prevent, identify, and correct CVC malpositioning could decrease harm to patients with this condition.

    The purpose of this work was to describe our experience in performing pulmonary angiography using the Hunter pulmonary catheter, manufactured by Cook, Inc., which is a modified 6F pigtail catheter with a "C-shaped" curve, designed for a brachiocephalic vein approach. One hundred twenty-three patients underwent pulmonary angiograms using the Hunter catheter between August 1997 and January 2002. Operator comments were gathered in 86 (70%) of the cases. The operator was, if possible, the most junior resident on the service. Thirty-nine operators participated in the survey. Efficacy, safety, and ease of use of the catheter were determined by operators' comments and ECG observations during the procedure. Corroborating clinical data were gathered from medical records. In 68 (79%) of the procedures that were commented upon, the operator described insertion into the pulmonary artery (PA) as easy; only 2 (2%) indicated difficulty in accessing the PA. In 41 (63%) of the bilateral angiograms that were commented upon, the operator described accessing the left PA from the right PA as easy; only 6 (9%) rated it as difficult and all were with an older technique in which the catheter was withdrawn to the pulmonary bifurcation without a wire or with only the soft tip of the wire in the pigtail and then rotated to the left main pulmonary artery. Thirty-one of the 41 patients who demonstrated premature ventricular contractions (PVCs) had a previous history of heart disease. Nineteen of the 39 patients who did not have PVCs had a history of heart disease (p = 0.018). The maneuverability and shape of the Hunter catheter make pulmonary angiography an easy procedure, even for operators with minimal experience and limited technical proficiency. PVCs demonstrated a statistically significant correlation with a positive patient history for cardiac disease, rather than being a universal risk.

    Peripherally inserted central catheters (PICC) are widely used to provide central venous access, often in chronically ill patients with long-term intravenous access requirements. There are a number of significant complications related to both insertion and maintenance of PICC lines, including catheter malposition, migration, venous thrombosis, and line fracture. The incidence of these complications is likely to rise as the number of patients undergoing intravenous outpatient therapy increases, with a corresponding rise in radiologist input. This paper provides an overview of the relevant peripheral and central venous anatomy, including anatomical variations, and outlines the complications of PICC lines. Imaging examples demonstrate the range of radiological findings seen in these complications.

    Full Text Available Migration of the tip of central venous catheters is not an uncommon event and the mechanism for this is not clear. Increased intrathoracic pressure due to coughing, sneezing or weight lifting, changing the body position or physical movements such as abduction or adduction of the arms is thought to be the cause of such migration. We present here a case of a patient with a port catheter tip that migrated from the left subclavian to the superior vene cava following extubation.

    Disinfection caps are increasingly being used to prevent catheter-associated bloodstream infections. These devices, designed for continuous passive disinfection of catheter hubs, are typically small and often brightly colored. As such, they have the potential to become pediatric airway and esophageal foreign bodies. We report two patients who developed esophageal foreign body following ingestion of disinfection caps. Given the increasing use of these devices, it is imperative that health care providers be aware of this potential iatrogenic problem. We propose that the use of disinfection caps may not be appropriate in pediatric patients with risk factors for foreign body ingestion.

    Full Text Available INTRODUCTION Central venous catheters (CVC are used in the treatment of critically ill patients. Indications for placement of CVCs include hemodynamic monitoring, administration of intravenous fluids, medications and total parenteral nutrition. MATERIAL AND METHODS We investigated risk factors and effects of glycopeptide antibiotics on the development of central venous catheter-related infections in 300 patients treated in intensive care units. A semiquntitative culture technique was used. The investigation included: age, diagnosis on admission, catheter insertion site, catheter duration, the first or next catheter and using of glycopeptide drugs. RESULTS 91 catheters (30.3% were colonised, catheter-related infection was found in 50 catheters (16.7%. Infections were more frequent in catheters inserted through the internal jugular vein than in subclavian venous catheters; they were also more frequent if duration of catheterization was longer than seven days, but less frequent in patients who received glycopeptide antibiotics. The isolated microorganism was Staphylococcus aureus. DISCUSSION According to the literature, a number of catheter-related risk factors for infections include: insertion site, type of catheter, the number of manipulations, inadequat asepsis, lumen number, type of antiseptic. The relative importance of one risk factor over another is difficult to assess, given that studies have no priority report. CONCLUSION The duration of catheterization and the insertion site were the most frequent risk factors for infection. The use of glycopeptide antibiotics during catheterization has protective effects.

    Full Text Available Objective: Percutaneous coronary intervention for anomalous right coronary artery (RCA originating from the left coronary cusp is challenging because of our current inability to coaxially engage the guiding catheter. Methods: We report a case of an 88-year-old woman with non-ST segment elevation myocardial infarction, with an anomalous RCA origin. Using either the Judkins-Left catheter or Amplatz-Left catheter was difficult because of RCA ostium tortuosity. Thus, we used steam to deform the Judkins-Left catheter, but back-up support was insufficient to deliver the stent. Results: We used GuideLiner®, a novel pediatric catheter with rapid exchange/monorail systems, to enhance back-up support. Conclusions: We were able to successfully stent with both the deformed Judkins-Left guiding catheter and GuideLiner® for an anomalous RCA origin.

    Coronary atherosclerosis is a complex disease accompanied by the development of plaques in the arterial wall. Since the vulnerability of the plaques depends on their composition, the appropriate treatment of the arteriosclerosis requires a reliable characterization of the plaques' geometry and content. The intravascular ultrasound (IVUS) imaging is capable of providing structural details of the plaques as well as some functional information. In turn, more functional information about the same plaques can be obtained from intravascular photoacoustic (IVPA) images since the optical properties of the plaque's components differ from that of their environment. The combined IVUS/IVPA imaging is capable of simultaneously detecting and differentiating the plaques, thus determining their vulnerability. The potential of combined IVUS/IVPA imaging has already been demonstrated in phantoms and ex-vivo experiments. However, for in-vivo or clinical imaging, an integrated IVUS/IVPA catheter is required. In this paper, we introduce two prototypes of integrated IVUS/IVPA catheters for in-vivo imaging based on a commercially available single-element IVUS imaging catheter. The light delivery systems are developed using multimode optical fibers with custom-designed distal tips. Both prototypes were tested and compared using an arterial mimicking phantom. The advantages and limitations of both designs are discussed. Overall, the results of our studies suggest that both designs of integrated IVUS/IVPA catheter have a potential for in-vivo IVPA/IVUS imaging of atherosclerotic plaques.

  7. Minimizing Hemodialysis Catheter Dysfunction: An Ounce of Prevention

    Directory of Open Access Journals (Sweden)

    Timmy Lee

    2012-01-01

    Full Text Available The maintenance of tunneled catheter (TC patency is critical for the provision of adequate hemodialysis in patients who are TC-dependent. TC dysfunction results in the need for costly and inconvenient interventions, and reduced quality of life. Since the introduction of TCs in the late 1980s, heparin catheter lock has been the standard prophylactic regimen for the prevention of TC dysfunction. More recently, alternative catheter locking agents have emerged, and in some cases have shown to be superior to heparin lock with respect to improving TC patency and reducing TC-associated infections. These include citrate, tissue plasminogen activator, and a novel agent containing sodium citrate, methylene blue, methylparaben, and propylparaben. In addition, prophylaxis using oral anticoagulants/antiplatelet agents, including warfarin, aspirin, ticlodipine, as well as the use of modified heparin-coated catheters have also been studied for the prevention of TC dysfunction with variable results. The use of oral anticoagulants and/or antiplatelet agents as primary or secondary prevention of TC dysfunction must be weighed against their potential adverse effects, and should be individualized for each patient.

    Central venous catheters (CVC) are used to provide vascular access during hemodialysis in patients with end-stage kidney disease. Despite several advantages and widespread use, CVCs have a high incidence rate of clot formation during the interdialytic phase (48 hrs). In an attempt the prevent clot formation, hospitals routinely administer heparin, an anticoagulant, into the catheter after a dialysis session. It has been reported, however, that up to 40% of the heparin solution will leak into the blood stream during the interdialytic phase, placing the patient at risk for systemic bleeding incidences. The aim of this study is to determine the role that advective-diffusive transport plays in the heparin leaking process. Numerical simulations of heparin convective mass transfer have been conducted, showing that while advective losses may be significant at the tip, previous studies may be overestimating the total amount of heparin leakage. To validate the quantitative prediction from the simulations, P.L.I.F. is used to experimentally measure heparin transport from CVCs placed in an idealized Superior Vena Cava with physically accurate pulsatile flow conditions. Improved understanding of flow near the catheter tip is applied to improve catheter design and heparin locking procedures.

    The central venous catheter (CVC) is a catheter placed into a large vein in the neck [internal jugular vein (IJV)], chest (subclavian vein or axillary vein) or groin (femoral vein). There are several situations that require the insertion of a CVC mainly to administer medications or fluids, obtain blood tests (specifically the "central venous oxygen saturation"), and measure central venous pressure. CVC usually remain in place for a longer period of time than other venous access devices. There are situations according to the drug administration or length of stay of the catheter that specific systems are indicated such as; a Hickman line, a peripherally inserted central catheter (PICC) line or a Port-a-Cath may be considered because of their smaller infection risk. Sterile technique is highly important here, as a line may serve as a port of entry for pathogenic organisms, and the line itself may become infected with organisms such as Staphylococcus aureus and coagulase-negative Staphylococci. In the current review we will present the complication of pneumothorax after CVC insertion.

  15. Vascular collateralization along ventriculoperitoneal shunt catheters in moyamoya disease.

    2013-06-01

    Surgically created openings such as bur holes can serve as avenues for the development of collateral blood supply to the brain in patients with moyamoya disease. When such collateralization occurs through preexisting shunt catheter sites, the potential exists for perioperative stroke if these vessels are damaged during revision of a ventricular catheter for shunt malfunction. In this paper the authors report on a series of patients with a history of ventriculoperitoneal (VP) shunts who later developed moyamoya disease and were found to have spontaneous transdural collateral vessels at ventricular catheter sites readily visualized on diagnostic angiography. A consecutive surgical series of 412 patients with moyamoya disease treated at Boston Children's Hospital from 1990 to 2010 were reviewed to identify patients with concomitant moyamoya and a VP shunt. The clinical records and angiograms of these patients were reviewed to determine the extent of bur hole collaterals through the shunt site. Three patients were identified who had VP shunts placed for hydrocephalus and subsequently developed moyamoya disease. All 3 patients demonstrated spontaneous transdural collaterals at the ventricular catheter bur hole, as confirmed by angiography during the workup for moyamoya disease. No patients required subsequent revision of their ventricular catheters following the diagnosis of moyamoya. All patients have remained stroke free and clinically stable following pial synangiosis. Although the association of moyamoya and shunted hydrocephalus is rare, it may present a significant potential problem for the neurosurgeon treating a shunt malfunction in this patient population, because shunt bur holes may become entry sites for the ingrowth of significant cortical transdural collateral blood supply to the underlying brain. Shunt revision might therefore be associated with an increased risk of postoperative stroke or operative-site hemorrhage in this population if this

    This study describes a modified Seldinger technique for 2- and 3-French peripherally inserted central venous catheters: A device similar to that used in heart catherisation with a standard micro-introducer serving as sheath and an arterial catheter serving as inner dilator was pushed forward over a wire guide that had before been inserted via a peripheral venous catheter. With this method 2-and 3-French catheters could be safely inserted into peripheral veins of 14 paediatric patients. In conclusion successful insertion of a small peripheral venous catheter offers in most cases a possibility for the placement of a central venous line.

    Central venous catheters are frequently used not only in intensive care patients. Attention is drawn to the possible displacements of catheters and to the need for correct radiological control of the catheter position. Since unrecognized extravascular position of the catheter is followed by serious complications s.e. tension pneumothorax and infusions into the pleural cavity or the mediastinum, adequate X-ray control has to be carried out with simultaneous administration of contrast medium. Correction of displaced catheters should be done under fluoroscopy.

    OBJECTIVE Accurate placement of ventricular catheters may result in prolonged shunt survival, but the best target for the hole-bearing segment of the catheter has not been rigorously defined. The goal of the study was to define a target within the ventricle with the lowest risk of shunt failure. METHODS Five catheter placement variables (ventricular catheter tip location, ventricular catheter tip environment, relationship to choroid plexus, catheter tip holes within ventricle, and crosses midline) were defined, assessed for interobserver agreement, and evaluated for their effect on shunt survival in univariate and multivariate analyses. De-identified subjects from the Shunt Design Trial, the Endoscopic Shunt Insertion Trial, and a Hydrocephalus Clinical Research Network study on ultrasound-guided catheter placement were combined (n = 858 subjects, all first-time shunt insertions, all patients 0.60). In the univariate survival analysis, however, only ventricular catheter tip location was useful in distinguishing a target within the ventricle with a survival advantage (frontal horn; log-rank, p = 0.0015). None of the other catheter placement variables yielded a significant survival advantage unless they were compared with catheter tips completely not in the ventricle. Cox regression analysis was performed, examining ventricular catheter tip location with age, etiology, surgeon, decade of surgery, and catheter entry site (anterior vs posterior). Only age (p < 0.001) and entry site (p = 0.005) were associated with shunt survival; ventricular catheter tip location was not (p = 0.37). Anterior entry site lowered the risk of shunt failure compared with posterior entry site by approximately one-third (HR 0.65, 95% CI 0.51-0.83). CONCLUSIONS This analysis failed to identify an ideal target within the ventricle for the ventricular catheter tip. Unexpectedly, the choice of an anterior versus posterior catheter entry site was more important in determining shunt survival than

    We describe a case of a 49-year-old woman with stage-IIIB lung adenocarcinoma who experienced an acute superior vena cava syndrome related to an implanted central venous catheter without associated venous thrombosis. The catheter was surgically implanted for chemotherapy. Superior vena cava syndrome appeared after the procedure and was due to insertion of the catheter through a subclinical stenosis of the superior vena cava. Complete resolution of the patient's symptoms was obtained using stent placement and endovascular repositioning of the catheter tip. (orig.)

    1998-03-01

    Fourteen severely ill ventilated patients in an intensive care unit, requiring short-term total parenteral nutrition, were examined for catheter-related infection. Microbiological analysis using Maki's SQ technique was carried out on catheter exit site, catheter hub, proximal subcutaneous segment of catheter and catheter up. Qualitative cultures were carried out on total parenteral nutrition and peripheral blood samples. Twenty six of 29 catheters removed (90%) were culture positive but only 7 catheters were related to positive blood cultures, giving a catheter-related bacteremia (CRB) rate of 24%. Haematogenous seeding was strongly implicated in 7/29 (24%) of catheters. Patients' skin flora appeared to be the main source of catheter-related infection. The organisms isolated for patients with CRB included coagulase-negative staphylococci, Acinetobacter and Klebsiella. It is suggested that to control infective complications of central venous catheters, emphasis should be focused on specialised intravenous therapy teams and the use of strict protocols for insertion and care of central lines.

The clinical sign of an occlusion is catheter malfunction and flushing is strongly recommended to ensure a well-functioning catheter. Therefore fluid dynamics, flushing techniques, and sufficient flushing volumes are important matters in adequate flushing in all catheter types. If a catheter is not in use, it is locked. For years, it has been thought that the catheter has to be filled with an anticoagulant to prevent catheter occlusion. Heparin has played a key role in locking venous catheters. However, the high number of risks associated with heparin forces us to look for alternatives. A long time ago, 0.9% sodium chloride was already introduced as locking solution in peripheral cannulas. More recently, a 0.9% sodium chloride lock has also been investigated in other types of catheters. Thrombolytic agents have also been studied as a locking solution because their antithrombotic effect was suggested as superior to heparin. Other catheter lock solutions focus on the anti-infective properties of the locks such as antibiotics and chelating agents. Still, the most effective locking solution will depend on the catheter type and the patient’s condition.

    Full Text Available Introduction. Bacterial colonization of catheter tips is common in regional anesthesia and is a suspected risk factor for infectious complications. This is the first study evaluating the effect of CHG-impregnated dressings on bacterial colonization of regional anesthesia catheters in a routine clinical setting. Methods. In this prospective study, regional anesthesia catheter infection rates were examined in two groups of patients with epidural and peripheral regional catheters. In the first group, regional anesthesia was dressed with a conventional draping. The second group of patients underwent catheter dressing using a CHG-impregnated draping. Removed catheters and the insertion sites were both screened for bacterial colonization. Results. A total of 337 catheters from 308 patients were analysed. There was no significant reduction of local infections in either epidural or peripheral regional anesthesia catheters in both CHG and conventional groups. In the conventional group, 21% of the catheter tips and 41% of the insertion sites showed positive culture results. In the CHG-group, however, only 3% of the catheter tips and 8% of the insertion sites were colonised. Conclusion. CHG dressings significantly reduce bacterial colonization of the tip and the insertion site of epidural and peripheral regional catheters. However, no reductions in rates of local infections were seen.

    Central venous catheter (CVC) day definitions do not consider concurrent CVCs. We examined traditional CVC day counts and resultant central line-associated bloodstream infection (CLABSI) rates with a CVC day definition that included concurrent CVCs. Accounting for concurrent CVCs increased device day counts by 8.5% but only mildly impacted CLABSI rates.

    Full Text Available OBJECTIVE: to seek the best evidence available in the literature concerning the knowledge produced and related to the techniques of intermittent and indwelling urinary catheterization, so as to place the nursing care given to patients submitted to urinary catheterization on a scientific foundation and to prevent urinary tract infections. METHOD: the literature search was undertaken in the Pubmed and Cochrane databases for the development of the integrative review. The sample was of 34 articles. These were analyzed by two independent researchers using an instrument adapted for ascertaining the level of evidence and the grade of recommendation, in addition to the use of the Jadad scale. RESULTS: the evidence available related to the nursing care for patients submitted to urinary catheterization is: the infection rate in the urinary tract does not alter whether the perineum is cleaned with sterile water or not, or with the use of povidone-iodine solution or chlorhexidine; or using clean or sterile technique. The use of an intermittent catheter with clean technique results in low rates of complications or infections compared to the use of an indwelling catheter. The removal of the catheter in up to 24 hours after surgery and the use of an antimicrobial-impregnated or hydrophilic-coated catheter reduce urinary tract infection . CONCLUSIONS: there are controversies in relation to periurethral cleansing technique, the type of material the catheter is made of, and some procedures for the maintenance and removal of the catheter. This review's results represent an updating of the nurse's conducts and decision-making for the prevention of urinary tract infections in urinary catheterization.OBJETIVO: buscar las mejores evidencias disponibles en la literatura sobre el conocimiento producido y relacionado a la técnica de cateterismo urinario intermitente y de demora para apoyar científicamente el cuidado de enfermería prestado al paciente sometido al

    Full Text Available Some nonsurgical steps have been introduced to remove an entrapped catheter. But occasionally, the majority of them fail, and we are forced to extract the catheter through an invasive procedure. This article depicts our team′s experience on the issue. When we found that the inserted epidural catheter was entrapped, we performed all recommended noninvasive maneuvers to release the catheter, but no progress was achieved. Therefore, after obtaining informed consent, we induced anesthesia and changed her to a prone position to explore her back. The intact catheter was removed easily in this stage. The authors believe, in this process, it would have been better if they had tried pulling the catheter in a prone position as a preliminary step. Furthermore, pulling the catheter in a prone position after injecting a muscle relaxant appeared to be more effective and saved the patient from the scheduled surgery.

    Full Text Available Abstract Backround We undertook a prospective study of all new central venous catheters inserted into patients in the intensive care units, in order to identify the risk factors and to determine the effect of glycopeptide antibiotics on catheter – related infections. Methods During the study period 300 patients with central venous catheters were prospectively studied. The catheters used were nontunneled, noncuffed, triple lumen and made of polyurethane material. Catheters were cultured by semiquantitative method and blood cultures done when indicated. Data were obtained on patient age, gender, unit, primary diagnosis on admission, catheter insertion site, duration of catheterization, whether it was the first or a subsequent catheter and glycopeptide antibiotic usage. Results Ninety-one (30.3% of the catheters were colonized and infection was found with 50 (16.7% catheters. Infection was diagnosed with higher rate in catheters inserted via jugular vein in comparison with subclavian vein (95% CI: 1.32–4.81, p = 0.005. The incidence of infection was higher in catheters which were kept in place for more than seven days (95% CI 1.05–3.87, p = 0.03. The incidence of infection was lower in patients who were using glycopeptide antibiotic during catheterization (95% CI: 1.49–5.51, p = 0.005. The rate of infection with Gram positive cocci was significantly lower in glycopeptide antibiotic using patients (p = 0.01. The most commonly isolated organism was Staphylococcus aureus (n = 52, 37.1%. Conclusion Duration of catheterization and catheter insertion site were independent risk factors for catheter related infection. Use of glycopeptide antibiotic during catheterization seems to have protective effect against catheter related infection.

    Full Text Available Introduction/Aim. Intravascular device placement (IVD is a part of everyday medical practice, however, its application is associated with a high risk of onset of nosocomial infections (NI and increased mortality and morbidity. Nosocomial blood infections (NBIs account for 10% of all the registered NI. NBIs are more frequent in patients with a placed IVD and it present an important risk factor for the onset of NBI, i.e. catheter-associated NBIs (CANBIs. Pathogenesis of CANBIs is complex and conditioned by the presence of different characteristics related to a catheter, patient and a specific causative organism. The most common CRBSI causes include coagulase-negative staphylococcus, S. aureus, Enterobacter spp, Candida spp, Klebsiella spp, Pseudomonas spp. and Enterococcus spp. Methods. All the patients hospitalized at the Intensive Care Department of the Clinic of Digestive Diseases over the period January 1, 2004-September 1, 2004 were retrospectively analyzed. The study included 107 patients in whom central venous catheter (CVC was placed for more than 48 h. All the causes isolated from a CVC segment were recorded. Culture, isolation and identification of the causative organisms were performed using standard microbiological methods in the Bacteriological Laboratory within the Emergency Center, Clinical Center of Serbia. Catheter segment samples (tip of the CVC 3-5 cm long were analyzed. Based on the insight into medical documentation, patients’ examination and medical staff interview, catheter and patient-related characteristics were recorded. Results. A total of 107 CVCs were analyzed, out of which 56 (52% were sterile while 51 (48% were colonized. The results of our study evidenced that total parenteral nutrition (TPN (p < 0.05, number of catheterization days (p < 0.05, and central venous pressure measurement (p < 0.05 were significantly associated with CVC colonization.

    Full Text Available Background. The first double-J (DJ stents were manufactured in 1978. Their J-shaped tips efficiently prevent their migration from kidneys and from the urinary bladder. Nowadays, DJ stents are in common use because they provide efficient and relatively safe urinary derivation between the kidney and the urinary bladder. We report this case with the aim to point out possible serious complications with long-term indwelling stents. Case report. The patient was admitted to hospital five years after the placement of DJ in a bad general condition, with symptoms of peritonitis. Radiological examination (plain abdominal film, computerized tomography, excretory urogram and cystography showed bulky calculosis at each tip of the stent, affunctional right kidney, vesicoureteral reflux through the DJ stent and ureter all the way to the right kidney, as well as a large amount of turbid liquid in the abdomen. In the course of the operation, the bulky stone with the DJ stent was removed form the urinary bladder, followed by a large amount of turbid liquid extracted from the abdomen. During adhesiolysis, a small intraperitoneal perforation through which a tip of the stent prolapsed, was found on the upper pole of the kidney. After that, nefrectomy was performed. The patient was discharged 18 days after the surgery. Conclusion. There are usually no complications with shortterm DJ stent urinary drainage. However, indwelling DJ stents can cause serious complications, such as migration, incrustration and fragmentation. DJ indwelling should be as short as possible. If indwelling stenting is necessary, the DJ stent should be replaced with a new one in due time, or another kind of derivation should be performed. Careful monitoring of patients could exclude any possibility of a stent being forgotten at all.

    To determine the efficacy of correction of a malfunctioning peritoneal dialysis catheter with guidewire and stiffener under fluoroscopic guidance. Between November 1994 and March 1997, we performed 15 manipulations in 12 patients in whom a dual-cuff, straight Tenckhoff peritoneal dialysis catheter had been implanted due to chronic renal failure. The causes of catheter malfunctioning were inadequate drainage of the dialysate(n=14) and painful dialysis(n=1). Under fluoroscopic guidance, adhesiolysis and repositioning of the malfunctioning catheter were performed with an Amplatz Super Stiff guidewire and the stiffener from a biliary drainage catheter. The results of procedures were categorized as either immediate or durable success, this latter being defined as adequate catheter function for at least one month after the procedure. Immediate success was achieved in 14 of 15 procedures (93%), and durable success in 7 of 15(47%). The mean duration of catheter function was 157 (range, 30 to 578) days. After manipulation, abdominal pain developed in eight patients and peritonitis in two, but with conservative treatment, these symptoms improved. The correction of a malfunctioning peritoneal dialysis catheter with guidewire and stiffener under fluoroscopic guidance is an effective means of restoring catheter function and may be an effective alternative to surgical reimplantation of the catheter, or hemodialysis.

    To evaluate prospectively the results of interventional radiologic placement of tunneled central venous catheters, and subsequent complications. Between April 1997 and April 1998, a total of 557 tunneled central venous catheters were percutaneously placed in 517 consecutive patients in an interventional radiology suite. The indications were chemotherapy in 533 cases, total parenteral nutrition in 23 and transfusion in one. Complications were evaluated prospectively by means of a chart review, chest radiography, central vein angiography and blood/catheter culture. The technical success rate for tunneled central venous catheter placement was 100% (557/557 cases). The duration of catheter placement ranged from 4 to 356 (mean, 112{+-}4.6) days; Hickman catheters were removed in 252 cases during follow-up. Early complications included 3 cases of pneumothorax(0.5%), 4 cases of local bleeding/hematoma(0.7%), 2 cases of primary malposition(0.4%), and 1 case of catheter leakage(0.2%). Late complications included 42 cases of catheter-related infection(7.5%), 40 cases of venous thrombosis (7.2%), 18 cases of migration (3.2%), 5 cases of catheter / pericatheter of occlusion(0.8%), and 1 case of pseudoaneurysm(0.2%). The infection rate and thrombosis rate per 1000 days were 1.57 and 1.50, respectively. The technical success rate of interventional radiologic placement of tunneled central venous catheters was high. In comparison to conventional surgical placement, it is a more reliable method and leads to fewer complications.

    To evaluate the impact of interventional radiological imaging and treatment of central venous port catheter complications. Materials and Methods: In this retrospective analysis 429 port catheter dysfunctions were evaluated in 393 port catheter systems for a total of 389 patients over a period of 10 years. The study included 193 (49.1 %) patients with radiologically implanted port catheter systems and 200 (50.9 %) referred patients with surgically implanted port systems. Port catheter dysfunctions were subdivided into early and late complications as well as into non-thrombotic and thrombotic events. After administration of contrast medium, the port system was visualized using digital subtraction angiography. Data were retrospectively collected from the in-house databases and then analyzed descriptively. Results: 429 contrast media injections via port catheters were performed in 393 port catheter systems. There were 359 (83.7 %) late complications and 70 (16.3 %) early complications. In 299 (69.7 %) cases thrombotic events occurred and 130 (30.3 %) non-thrombotic events were recorded. The most common reason for contrast media injection via port catheter system was port catheter-related thrombosis in 269 (62.7 %) cases. 70 (16.3 %) catheter migrations and 30 (7.0 %) fibrin sheath formations were detected. 18 (4.2 %) port needle malfunctions could be resolved through needle exchange. All 15 (3.5 %) catheter disconnections had to be revised in all cases. Also six port explantations were performed in 6 (1.4 %) catheter fractures. Conclusion: The possibilities of angiographic imaging and interventional radiological correction of port catheter dysfunctions must be exploited fully in order to avoid premature port explantation.

    Intracranial epidural abscesses are uncommon lesions, being more frequents in older children and adults. They commonly arise as a result of direct extension of a preexisting infection and rarely present with focal deficit. We present a case of a 11-days old preterm infant who developed an intracranial epidural abscess as a result of an infected scalp vein catheter. The diagnosis was made on the basis of the cranial ultrasound and CT scan images. An identified strain of Enterococcus faecium was cultured from all the samples. The patient underwent a right frontal craniotomy with drainage of the abscess and a 2-week total course of intravenous antibiotics was administrated. CT scan imaging 3 week after the procedure demonstrated no evidence of residual lesion. When present, a scalp vein catheter, in absence of others predisponing factors, must be considered as an etiologic agent for an intracranial epidural abscess in this age-group.

    Full Text Available We report a 54-year-old woman with the history of end-stage renal disease (ESRD who was admitted to our hospital because of volume overload. Due to long-term use of peripheral veins and arteriovenous fistula (AVF failure, central venous catheterization was the only choice for hemodialysis. She developed right upper extremiti’s pain and paresis during hemodialysis. A posteroanterior chest x-ray showed the catheter tip was accidently pushed from right internal jugular vein into right subclavian vein during hemodialysis by the dialysis center nurse. Therefore, we believe that the physician should be aware of any changes in the catheter size after insertion. And a chest x-ray should ensure the catheter’s correct position in any patient who develops complications.

    Full Text Available Background and objective: The present study aimed to evaluate whether right subclavian vein (SCV catheter insertion depth can be predicted reliably by the distances from the SCV insertion site to the ipsilateral clavicular notch directly (denoted as I-IC, via the top of the SCV arch, or via the clavicle (denoted as I-T-IC and I-C-IC, respectively. Method: In total, 70 SCV catheterizations were studied. The I-IC, I-T-IC, and I-C-IC distances in each case were measured after ultrasound-guided SCV catheter insertion. The actual length of the catheter between the insertion site and the ipsilateral clavicular notch, denoted as L, was calculated by using chest X-ray. Results: L differed from the I-T-IC, I-C-IC, and I-IC distances by 0.14±0.53, 2.19±1.17, and -0.45 ±0.68 cm, respectively. The mean I-T-IC distance was the most similar to the mean L (intraclass correlation coefficient = 0.89. The mean I-IC was significantly shorter than L, while the mean I-C-IC was significantly longer. Linear regression analysis provided the following formula: Predicted SCV catheter insertion length (cm = -0.037 + 0.036 × Height (cm + 0.903 × I-T-IC (cm (adjusted r2 =0.64. Conclusion: The I-T-IC distance may be a reliable bedside predictor of the optimal insertion length for a right SCV cannulation.

    Full Text Available This work addresses the design of an active multi-link micro-catheter actuated by Shape Memory Alloy (SMA micro actuators. This may be a response to one medical major demand on such devices, which will be useful for surgical explorations and interventions. In this paper, we focus on a training and design simulator dedicated to such catheters. This simulator is based on an original simulation platform (OpenMASK. The catheter is a robotic system, which is evaluated by a dynamical simulation addressing a navigation task in its environment. The design of the prototype and its mechanical model are presented. We develop an interaction model for contact. This model uses a real medical database for which distance cartography is proposed. Then we focus on an autonomous control model based on a multi-agent approach and including the behaviour description of the SMA actuators. Results of mechanical simulations including interaction with the ducts are presented. Furthermore, the interest of such a simulator is presented by applying virtual prototyping techniques for the design optimization. This optimization process is achieved by using genetic algorithms at different stages with respect to the specified task.

  16. Intracardiac Echocardiography during Catheter-Based Ablation of Atrial Fibrillation

    2012-01-01

    Full Text Available Accurate delineation of the variable left atrial anatomy is of utmost importance during anatomically based ablation procedures for atrial fibrillation targeting the pulmonary veins and possibly other structures of the atria. Intracardiac echocardiography allows real-time visualisation of the left atrium and adjacent structures and thus facilitates precise guidance of catheter-based ablation of atrial fibrillation. In patients with abnormal anatomy of the atria and/or the interatrial septum, intracardiac ultrasound might be especially valuable to guide transseptal access. Software algorithms like CARTOSound (Biosense Webster, Diamond Bar, USA offer the opportunity to reconstruct multiple two-dimensional ultrasound fans generated by intracardiac echocardiography to a three-dimensional object which can be merged to a computed tomography or magnetic resonance imaging reconstruction of the left atrium. Intracardiac ultrasound reduces dwell time of catheters in the left atrium, fluoroscopy, and procedural time and is invaluable concerning early identification of potential adverse events. The application of intracardiac echocardiography has the great capability to improve success rates of catheter-based ablation procedures.

    Full Text Available This descriptive quantitative study aimed to analyze the prevalence of microorganisms and the antimicrobial sensitivity profile from urine cultures of patients with catheter-associated urinary tract infection. We reviewed 394 medical records of adults hospitalized in the Intensive Care Units of the University Hospital of Londrina, Paraná, Brazil, from April to December 2011. The prevalence of catheter-associated urinary tract infection was of 34.0% (134 and 2.2% (3 of these patients developed sepsis. The most common microorganisms found in the urine cultures were Candida sp (44.4%, Acinetobacter baumannii (9.7% and Pseudomonas aeruginosa (9.2%. This last one showed resistance of 86.7% to third-generation cephalosporins and the Acinetobacter baumannii showed resistance of 83.3% to carbapenems. Klebsiella pneumonia had 87.5% of resistance to third and fourth generation cephalosporins and 75.0% to carbapenems. We concluded that bacterial resistance is frequent in catheter-associated urinary tract infection and that we should emphasize the control measures.

    Ventriculoperitoneal (VP) shunt placement is the mainstay of treatment for hydrocephalus, yet shunts remain vulnerable to a variety of complications. Although fat droplet migration into the subarachnoid space and cerebrospinal fluid pathways following craniotomy has been observed, a VP shunt obstruction with fat droplets has never been reported to our knowledge. We present the first reported case of VP shunt catheter obstruction by migratory fat droplets in a 55-year-old woman who underwent suboccipital craniotomy for removal of a metastatic tumor of the left medullocerebellar region, without fat harvesting. A VP shunt was inserted 1month later due to communicating hydrocephalus. The patient presented with gait disturbance, intermittent confusion, and pseudomeningocele 21days after shunt insertion. MRI revealed retrograde fat deposition in the ventricular system and VP shunt catheter, apparently following migration of fat droplets from the fatty soft tissue of the craniotomy site. Spinal tap revealed signs of aseptic meningitis. Steroid treatment for aseptic "lipoid" meningitis provided symptom relief. MRI 2months later revealed partial fat resorption and resolution of the pseudomeningocele. VP shunt malfunction caused by fat obstruction of the ventricular catheter should be acknowledged as a possible complication in VP shunts after craniotomy, even in the absence of fat harvesting.

    Optoacoustic sensing is a hybrid technique that combines the advantages of high sensing depth of ultrasound with contrast of optical absorption. In this study a miniature optoacoustic probe that can characterize the target properties located at the distal end of a catheter is investigated. The probe includes an optical fiber to illuminate the target with the pulsed laser light and a hydrophone to detect the generated optoacoustic signal. The probe is designed for the forwardsensing and therefore the acoustic signal propagates along the tube before being detected. Due to the circular geometry, the waves inside the tube are highly complex. A three dimensional numerical simulation is performed to model the optoacoustic wave generation and propagation inside the water filled cylindrical tubes. The effect of the boundary condition, tube diameter and target size on the detected signal is systematically evaluated. A prototype of the probe is made and tested for detecting an absorbing target inside a 2mm diameter tube submerged in water. The preliminary experimental results corresponding to the simulation is acquired. Although many different medical applications for this miniature probe may exist, our main focus is on detecting the occlusion inside the ventricular shunts. These catheters are used to divert the excess cerebrospinal fluid to the absorption site and regulate inter cranial pressure of hydrocephalous patients. Unfortunately the malfunction rate of these catheters due to blockage is very high. This sensing tool could locate the occluding tissue non-invasively and can potentially characterize the occlusion composites by scanning at different wavelengths of the light.

    The purpose of this retrospective study was to report 11 cases of severe vascular complications after central venous catheter misplacement. For each patient, data collection included body mass index, the diagnosis at admission, the site of the procedure, the type of catheter, coagulation parameters, the imaging modalities performed and the applied treatment. Eight patients had a lesion of the subclavian artery. Brachiocephalic vein perforations were assessed in three more patients. All patients had a chest roentgenogram after the procedure, six a CT examination, and four an angiographic procedure. Seven patients had a body mass index above 30, and 5 patients had coagulation disorders prior to the procedure. Seven patients were conservatively managed, 2 patients died despite resuscitation, 1 patient was treated with a stent graft, and one by superselective embolization. Subclavian or jugular vein temporary catheter positioning is a practical approach. Identification of any iatrogenic perforation of the subclavian artery or central veins urges obtainment a chest roentgenogram and, when required, a chest CT, selective angiograms or venograms. Body mass index superior to 30, previous unsuccessful catheterization attempts, and coagulation factor depletion seemed to account for risk factors. Recognition of clinical and radiological complications is mandatory. (orig.)

Traditionally, inserted large-bore suprapubic catheters may cause fatal complications. During the past decade, we used a small central venous catheter (CVC suprapubicly in 16 male patients for the purpose of urinary drainage, when transurethral catheterization failed. The procedure is performed in no more than 10 minutes. Success rate was 100% and this approach did not lead to any complications. In conclusion, placing a CVC for suprapubic drainage is a safe method with a high success rate and we recommend it in patients with failed transurethral catheterization after a few attempts (2–3 attempts.

    The common condition of atrial fibrillation is often treated by cutting diseased cardiac tissue to disrupt abnormal electrical conduction pathways. Heating abnormal tissue with electromagnetic power provides a minimally invasive surgical alternative to treat these cardiac arrhythmias. Radio frequency ablation has become the method of choice of many physicians. Recently, microwave power has also been shown to have great therapeutic benefit in medical treatment requiring precise heating of biological tissue. Since microwave power tends to be deposited throughout the volume of biological media, microwave heating offers advantages over other heating modalities that tend to heat primarily the contacting surface. It is also possible to heat a deeper volume of tissue with more precise control using microwaves than with purely thermal conduction or RF electrode heating. Microwave Cardiac Ablation (MCA) is used to treat heart tissue that allows abnormal electrical conduction by heating it to the point of inactivation. Microwave antennas that fit within catheter systems can be positioned close to diseased tissue. Specialized antenna designs that unfurl from the catheter within the heart can then radiate specifically shaped fields, which overcome problems such as excessive surface heating at the contact point. The state of the art in MCA is reviewed in this paper and a novel catheter-based unfurling wide aperture antenna is described. This antenna consists of the centre conductor of a coaxial line, shaped into a spiral and insulated from blood and tissue by a non-conductive fluid filled balloon. Initially stretched straight inside a catheter for transluminal guiding, once in place at the cardiac target, the coiled spiral antenna is advanced into the inflated balloon. Power is applied in the range of 50-150 W at the reserved industrial, scientific and medical (ISM) frequency of 915 MHz for 30-90 s to create an irreversible lesion. The antenna is then retracted back into the

Malpositioned central catheters have been reported to induce cardiac tachyarrhythmia in adult populations and there are case reports within the neonatal population. We present a case of a preterm neonate with a preexisting umbilical venous catheter (UVC, who then developed a supraventricular tachycardia (SVT. This was initially treated with intravenous adenosine with transient reversion. Catheter migration was subsequently detected, with the UVC tip located within the heart. Upon withdrawal of the UVC and a final dose of adenosine, the arrhythmia permanently resolved. Our literature review confirms that tachyarrhythmia is a rare but recognised neonatal complication of malpositioned central venous catheters. We recommend the immediate investigation of central catheter position when managing neonatal tachyarrhythmia, as catheter repositioning is an essential aspect of management.

    Introduction. Central venous catheters (CVC) have been inserted percutaneously since 1989. This technique has been adapted for transhepatic insertion of large-bore catheters in children with occluded central veins. Materials and methods. Three children aged 5, 11, and 12 years required hemodialysis or plasmaphoresis for treatment of life-threatening conditions. All central veins were occluded, thus transhepatic insertion of a large-bore catheter was necessary. All children underwent successful placement using a combination of ultrasound guidance and fluoroscopy. No complications occurred. Discussion. Transhepatic insertion of large-bore catheters can be performed safely in children. Catheter removal should be accompanied by track embolization to prevent exsanguinating hemorrhage. Conclusion. Transhepatic insertion of dialysis catheters is a safe alternative in children with occluded central veins. (orig.) With 2 figs., 7 refs.

    Staphylococcus spp. is a major cause of device-related infections. However, the mechanisms of deep-tissue infection by staphylococci from the skin surface remain unclear. We performed in vitro experiments to determine how staphylococci are transferred from the surface to the deeper layers of agar along the catheter for different strains of Staphylococcus aureus with respect to bacterial concentrations, catheter movements, and biofilm formation. We found that when 5-mm reciprocal movements of the catheter were repeated every 8h, all catheter samples of S. aureus penetrated the typical distance of 50mm from the skin to the epidural space. The number of reciprocal catheter movements and the depth of bacterial growth were correlated. A greater regression coefficient for different strains implied faster bacterial growth. Enhanced biofilm formation by different strains implied larger regression coefficients. Increased biofilm formation ability may accelerate S. aureus transport along a catheter due to physical movements by patients.

    Full Text Available Backgraund/Aim. Hemodialysis catheter, as an integral part of hemodialysis, is a catheter placed into the jugular, subclavian and femoral vein. The most common catheter-related complications are infections and thrombosis. The aim of the study was to analyze the prevalence of complications associated with differently inserted central-vein catheters for hemodialysis. Methods. The study was organized as a prospective examination during the period from December 2003 to November 2006, and included all patients who needed an active depuration by hemodialysis, hospitalized at the Clinical Center Kragujevac. The subject of the study were 464 centralvein catheters inserted during the mentioned period and there were recorded all complications related to the placement and usage of catheters. Results. The largest percent of inserted catheters was into the femoral vein − 403 (86.8%, significantly less into the jugular vein − 42 (9.2%, while into the subclavian vein there were placed only 19 catheters (4%. The average of femoral catheter functioning was 17 catheter days, in jugular catheters it was 17.3 days while the subclavian catheters had an average rate of functioning of 25.9 catheter days; there was found a statistically significant difference regarding the duration of functioning (p = 0.03. By microbe colonization of smear culture of the skin at the catheter insertion site, in clinically present suspicion of catheter infection, there was obtained a positive finding in 5.5% of catheters placed into the femoral vein and 7.1% of catheters instilled into the jugular vein, of which Staphylococcus aureus was the most important bacterial type, without statistically significant difference (p = 0.51. Haemoculture, done when there was a suspicion of bacteriemia, was positive in 3.7% of the patients with femoral and 4.8% with jugular catheters; Staphylococcus aureus was the most common bacteria type, but there was no statistically significant difference (p

    Purpose: To determine whether alternative HDR prostate brachytherapy catheter patterns can result in improved dose distributions while providing better access and reducing trauma. Methods: Prostate HDR brachytherapy uses a grid of parallel needle positions to guide the catheter insertion. This geometry does not easily allow the physician to avoid piercing the critical structures near the penile bulb nor does it provide position flexibility in the case of pubic arch interference. On CT data from ten previously-treated patients new catheters were digitized following three catheter patterns: conical, bi-conical, and fireworks. The conical patterns were used to accommodate a robotic delivery using a single entry point. The bi-conical and fireworks patterns were specifically designed to avoid the critical structures near the penile bulb. For each catheter distribution, a plan was optimized with the inverse planning algorithm, IPSA, and compared with the plan used for treatment. Irrelevant of catheter geometry, a p...

    Objective To review the application of Y-venous indwelling needle in continuous arterial pressure monitoring. Methods Fifty surgical patients underwent artery cannulation during the anesthesia in January 2010 to October 2010. The puncture sides were randomly chosen; if the Y-venous indwelling needle was used on left radial artery, then artery puncture needle on the contraleteral radial artery, and vice versa. Complications of puncture were compared between two groups. Results There were no significant differences in the average time of puncture, arterial pressure variability and time variability. The successful rate of puncture using Y-venous indwelling needle was higher than that using artery puncture needle, and there was almost no pollution when Y-venous indwelling needle is used. Conclusion The Y-venous indwelling needle can be a feasible choice in radial artery cannulation, with advantages of low cost, high successful rate, little pollution and more visibility.%目的 通过动脉专用穿刺针和Y型静脉留置针用于桡动脉穿刺的比较,探讨两者的优缺点.方法 50例全身麻醉患者随机选用美国BD公司的动脉穿刺针,对侧选用威海洁瑞一次性使用Y型静脉留置针行双侧桡动脉穿刺.比较两者首次穿刺成功率、穿刺时间、血液污染率、动脉压升降实验、升降时间及动脉血气分析.结果 两者在穿刺时间、动脉压升降实验、升降时间及动脉血气分析方面差异无统计学意义(P>0.05);Y型静脉留置针的首次穿刺成功率较高(P<0.05),血液污染低(P<0.01).结论 采用Y型静脉留置针行动脉穿刺置管,可以获得和常规使用的专用穿刺针相同的效果,且价廉、首次穿刺成功率高、污染少、判断直观,值得进一步推广应用.

    Full Text Available Abstract Background Antimicrobial catheters have been utilized to reduce risk of catheter colonization and infection. We aimed to determine if there is a greater than expected risk of microorganism-specific colonization associated with the use of antimicrobial central venous catheters (CVCs. Methods We performed a meta-analysis of 21 randomized, controlled trials comparing the incidence of specific bacterial and fungal species colonizing antimicrobial CVCs and standard CVCs in hospitalized patients. Results The proportion of all colonized minocycline-rifampin CVCs found to harbor Candida species was greater than the proportion of all colonized standard CVCs found to have Candida. In comparison, the proportion of colonized chlorhexidine-silver sulfadiazine CVCs specifically colonized with Acinetobacter species or diphtheroids was less than the proportion of similarly colonized standard CVCs. No such differences were found with CVCs colonized with staphylococci. Conclusion Commercially-available antimicrobial CVCs in clinical use may become colonized with distinct microbial flora probably related to their antimicrobial spectrum of activity. Some of these antimicrobial CVCs may therefore have limited additional benefit or more obvious advantages compared to standard CVCs for specific microbial pathogens. The choice of an antimicrobial CVC may be influenced by a number of clinical factors, including a previous history of colonization or infection with Acinetobacter, diphtheroids, or Candida species.

    Insertion of a suprapubic catheter is one of the essential skills that all surgeons should master. It provides an alternative way to drain the bladder in cases where urethral catheterization is contraindicated or deemed difficult. It also has a role in elective cases where long-term drainage of the bladder is required. In this article, we discuss the MediPlus suprapubic catheter kit, which offers a new and potentially promising technique for safe introduction of the catheter into the bladder.

    Urinary catheters are widely used for hospitalized patients and are often associated with high rates of urinary tract infection. We evaluated in vitro the antiadherence activity of a novel antiseptic Gendine-coated urinary catheter against several multidrug-resistant bacteria. Gendine-coated urinary catheters were compared to silver hydrogel-coated Foley catheters and uncoated catheters. Bacterial biofilm formation was assessed by quantitative culture and scanning electron microscopy. These data were further correlated to an in vivo rabbit model. We challenged 31 rabbits daily for 4 days by inoculating the urethral meatus with 1.0 x 10(9) CFU streptomycin-resistant Escherichia coli per day. In vitro, Gendine-coated urinary catheters reduced the CFU of all organisms tested for biofilm adherence compared with uncoated and silver hydrogel-coated catheters (P < 0.004). Scanning electron microscopy analysis showed that a thick biofilm overlaid the control catheter and the silver hydrogel-coated catheters but not the Gendine-coated urinary catheter. Similar results were found with the rabbit model. Bacteriuria was present in 60% of rabbits with uncoated catheters and 71% of those with silver hydrogel-coated catheters (P < 0.01) but not in those with Gendine-coated urinary catheters. No rabbits with Gendine-coated urinary catheters had invasive bladder infections. Histopathologic assessment revealed no differences in toxicity or staining. Gendine-coated urinary catheters were more efficacious in preventing catheter-associated colonization and urinary tract infections than were silver hydrogel-coated Foley catheters and uncoated catheters.

    To evaluate the technical aspects, results and complications of the percutaneous radiologic placement of peritoneal dialysis catheters. Between December 1999 and April 2001, 26 peritoneal dialysis catheters were placed percutaneously in 26 consecutive patients by interventional radiologists. The patient group consisted of 16 men and ten women with a mean age of 55 (range, 30-77) years. The results and complications arising were reviewed, and the expected patency of the catheters was determined by means of Kaplan-Meier survival analysis. The technical success rate for catheter placement was 100% (26/26 patients). Severe local bleeding occurred in one patient due to by inferior epigastric artery puncture, and was treated by compression and electronic cautery. The duration of catheter implantation ranged from 1 to 510 days and the patency rate was 416{+-}45 days. Catheter malfunction occurred in four patients. In two, this was restored by manipulation in the intervention room, and in one, through the use of urokinase. In three patients, peritonitis occurred. Catheters were removed from four patients due to malfunction (n=2), peritonitis (n=1), and death (n=1). Percutaneous radiologic placement of a peritoneal dialysis catheter is a relatively simple procedure that reduces the complication rate and improves catheter patency.

    More than 40% of nosocomial infections are those of the urinary tract, most of these occurring in catheterized patients. Bacterial colonization of the urinary tract and catheters results not only in infection, but also various complications, such as blockage of catheters with crystalline deposits of bacterial origin, generation of gravels and pyelonephritis. The diversity of the biofilm microbial community increases with duration of catheter emplacement. One of the most important pathogens in this regard is Proteus mirabilis. The aims of this study were to identify and assess particular virulence factors present in catheter-associated urinary tract infection (CAUTI) isolates, their correlation and linkages: three types of motility (swarming, swimming and twitching), the ability to swarm over urinary catheters, biofilm production in two types of media, urease production and adherence of bacterial cells to various types of urinary tract catheters. We examined 102 CAUTI isolates and 50 isolates taken from stool samples of healthy people. Among the microorganisms isolated from urinary catheters, significant differences were found in biofilm-forming ability and the swarming motility. In comparison with the control group, the microorganisms isolated from urinary catheters showed a wider spectrum of virulence factors. The virulence factors (twitching motility, swimming motility, swarming over various types of catheters and biofilm formation) were also more intensively expressed.

    Percutaneous endoscopic gastrostomy tube is the modality of choice for long-term enteral nutrition. In the event that replacement tubes are not available, urinary catheters can be used to maintain patency of the gastrostomy tract. This study reports our experience in a nurse-led service using Foley catheters as temporary gastrostomy tubes and the associated complications. Patients who had used Foley catheter as gastrostomy tube over a 2-year period (Jan 2011 to December 2012) were studied. Twenty-one patients had used Foley catheters as a temporary gastrostomy tube, and 12 (57.4%) did not experience any complications, including three patients who were still using Foley catheters at a median of 15 months (range 3-18). Two patients preferred the Foley catheter as feeding tubes. Six patients had replacements with formal balloon replacement tubes, and two patients did not require replacement. Complications occurred in nine (42.6%) patients: repeated burst Foley catheter balloon with peristomal leakage (n = 4), lumen blockage (n = 1), and catheter migration resulting in small bowel obstruction (n = 4). All complications were successfully managed with tube replacements. We showed that in a nurse-led service, using a Foley catheter as a temporary feeding gastrostomy tube is safe, but requires monitoring for complications.

    Central venous catheters are used for delivering medications and parenteral nutrition, measuring hemodynamic variations, and providing long-term intravenous access. In our clinic, during liver transection using a living-liver donor, peripherally inserted central venous catheters are generally preferred because they involve a less invasive technique with a lower risk of complications. In this report, we present the case of a 36-year-old male liver donor into whom we peripherally inserted a central venous catheter from his left basilic vein. After transecting the hepatic vein, the surgeon found foreign material inside the venous lumen, which turned out to be the distal segment of the catheter.

    There are concerns about secondary extracorporeal membrane oxygenation (ECMO) catheter infections in bacteremic patients. We investigated the association between blood stream infection (BSI) and ECMO catheter colonization. From January 2012 to August 2014, 47 adults who received ECMO support were enrolled. The ECMO catheter tip was cultured at the end of the ECMO procedure. The enrolled patients were classified into two groups according to the presence of BSI during ECMO support and analyzed with respect to ECMO catheter colonization. Of 47 cases, BSI during ECMO was identified in 13 patients (27.7 %). ECMO catheter colonization was identified in 6 (46.2 %) patients in the BSI group and 3 (8.8 %) in the non-BSI group. BSI during ECMO support was independently associated with ECMO catheter colonization [odds ratio (OR) 5.55; 95 % confidence interval (CI) 1.00-30.73; p = 0.049]. The organisms colonizing ECMO catheters in the setting of primary BSI were predominantly Gram-positive cocci and Candida species. Acinetobacter baumannii was the most common colonizing pathogen in the setting of secondary BSI. All the organisms colonizing ECMO catheters were multi-drug resistant organisms, including methicillin-resistant S. aureus, Candida glabrata, and carbapenem-resistant A. baumannii. ECMO catheters may become contaminated with multi-drug resistant pathogens in the presence of BSI. Therefore, ECMO should be applied cautiously in septic patients with bacteremia caused by multi-drug resistant pathogens.

    Full Text Available The fabrication and characterization of forward-looking active catheter actuated by titanium-nickel (Ti-Ni shape memory alloy (SMA springs are described. The catheter has been designed for wide-range observation of an affected area inside a blood vessel when the blood vessel is occluded. The developed active catheter consists of eight Ti-Ni SMA spring actuators for actuation of catheter tip, an ultrasonic transducer for forward-looking, a guide wire, a polyurethane tube for coating, and spiral wirings for realization of various flexure motions of catheter tip using Ti-Ni SMA actuators. The size of the catheter is 3.5 mm in diameter and 60 mm in length of the sum of transducer and actuator sections. Ti-Ni SMA springs were fabricated from a Ti-50.9at.%Ni sheet by electrochemical etching with a mixed solution of ethanol and lithium chloride. The catheter was assembled by hand under a stereomicroscope. The tip of the produced catheter was able to move in parallel toward at least eight directions by controlling an applied current to Ti-Ni SMA springs. We have confirmed that the active catheter was able to observe an object settled in the front.

    Central venous catheter-related blood stream infections (CR-BSIs) are a serious complication in patients with hematological malignancies. However, it remains unclear whether there is a difference in the rate of CR-BSI associated with the conventional type of central venous catheters (cCVCs) and peripherally inserted CVCs (PICCs) in such patients. To address this question, we retrospectively investigated the incidence of CR-BSIs associated with PICCs versus cCVCs in patients with hematological malignancies. We used PICCs in all consecutive patients requiring CVC placement between February 2009 and February 2013. We compared the CR-BSI rate in patients with PICCs with that in patients with cCVCs treated between September 2006 and January 2009 (control group). Eighty-four patients received PICCs and 85 received cCVCs. The most common reason for removal due to catheter-related complications was CR-BSI. The CR-BSI rate in the PICC group was significantly lower than that in the cCVC group (PICCs: 1.23/1000 catheter days; cCVCs: 5.30/1000 catheter days; P Catheter-related complications other than CR-BSIs occurred at an extremely low rate in the PICC group. The median catheter-related complication-free survival duration was significantly longer in the PICC group than in the cCVC group. Our study shows that PICCs are useful in patients with hematological malignancies.

    Full Text Available Infection of permanent catheters (Permcath in hemodialysis (HD patients can lead to catheter removal. The successful use of an antibiotic-lock to treat infection has reported good results in the treatment of catheters′ infections. This study was designed to evaluate the impact of the intraluminal vancomycin in comparison with intravenous antibiotic administration. We included 67 (37 males and 30 females chronic HD patients requiring Permcath insertion at our tertiary care hospital from July 2004 to June 2007. We studied two subgroups: an intervention group, which received 500 mg vancomycin infusion via both lumens of the Permcath and antibiotic lock of 1.5 mL each 48 hours with 1 g i.v. ceftriaxone every 12 hours for 7 days, followed by oral antibiotics according to the culture for three weeks; and a control group, which received 500 mg intravenous vancomycin with daily 100-150 mg amikacin intravenously. Our endpoint was the rate of catheter removal. The patients characteristics including age, sex, time of insertion of the catheter and number of dialysis sessions per week did not differ between both subgroups. Of 28 patients in the intervention group, there was one catheter removal, and of 39 patients in the control group, there were 22 catheter removals, (P< 0.001. We conclude that administration of vancomycin as an antibiotic-lock in permcaths is more effective than its mere intravenous injection, and can increase the life span of catheters.

    Epidural block is achieved either by single injection of local anesthetic through an epidural needle or as a continuous block by infusion pump through an epidural catheter. Complications associated with epidural catheters include breakage, entrapment, and knotting. Knotting of epidural catheters is very rare, but knotting in lumbar epidural catheters has been reported in a number of studies, and most of these cases involved removal difficulty. We report a case in which we inserted a cervical epidural catheter in a patient who was experiencing severe post-herpetic neuralgia and then removed the knotted catheter without complications.

We report the case of a 79-year-old woman on hemodialysis through a twin catheter in the right internal jugular vein, presenting with superior vena cava (SVC) syndrome with patent SVC. The clinically driven endovascular therapy was conducted to treat the venous syndrome with a unilateral left brachiocephalic stent-graft without manipulation of the well-functioning catheter. The follow-up was uneventful until death 94 months later.

    Preventing catheter-associated urinary tract infections is in the forefront of health care quality. However, nurse and physician engagement is a common barrier in infection prevention efforts. After implementation of a multidisciplinary catheter-associated urinary tract infection (CAUTI) prevention campaign, we studied the impact of our campaign and showed its association with reducing the CAUTI rate and catheter utilization and the positive effect on health care workers' engagement and perspectives. CAUTI prevention campaigns can lead to lower infection rates and change health care workers' perspective.

    Catheter-related bacteremia (CRB) is a typical complication of hemodialysis catheter use. Catheter lumen colonization by pathogens is regarded as a direct cause of CRB. Once settled, the catheter biofilm increases the risk of developing infection, thus necessitating insertion replacement and antibiotic treatment. The study assessed the self-sufficient efficacy of taurolidine-citrate-heparin lock solution in eradicating catheter biofilm bacteria and keeping it sterile in patients on hemodialysis. Twenty-nine chronic patients on hemodialysis with tunneled and nontunneled catheters locked with a heparin filling (the mean time of heparin lock use -30.1 ± 2.0 days) and subsequently converted to a taurolidine-citrate-heparin filling were included. Peripheral vein and catheter lumen blood cultures were obtained before the filling change and after taurolidine-citrate-heparin lock use (mean time 33.8 ± 7.6 days). Twenty-four participants with tunneled and nontunneled catheters locked with taurolidine-citrate-heparin filling served as the control group. During the heparin-locking period, CRB was diagnosed in 3 cases (only nontunneled catheters). The catheter blood cultures findings were positive in 23 patients (10 temporary and 13 permanent catheters), whereas both the catheter and peripheral vein blood cultures were sterile in 3 of 29 subjects (only permanent catheters). Irrespective of catheter type (tunneled or nontunneled), repeated culture revealed no pathogens in any of the 23 patients with initial positive catheter blood culture, after the use of taurolidine-citrate-heparin filling. No positive blood culture was noted in the control group. The taurolidine-citrate-heparin lock solution effectively eradicated pathogens from nontunneled and tunneled catheter biofilms and helped to maintain catheter lumen sterility.

    This study was performed to investigate the effect of the transition from barn feeding to pasture on the pattern of reticuloruminal pH values in 8 multiparous dairy cows. A indwelling wireless data transmitting system for pH measurement was given to 8 multiparous cows orally. Reticuloruminal pH values were measured every 600 s over a period of 42 days. After 7 days of barn feeding (period 1), all of the animals were pastured with increasing grazing times from 2 to 7 h/day over 7 days (period 2). From day 15 to day 21 (period 3), the cows spent 7 h/day on pasture. Beginning on day 22, the animals had 20 h/day access to pasture (day and night grazing). To study reticuloruminal adaptation to pasture feeding, the phase of day and night grazing was subdivided into another 3 weekly periods (periods 4-6). Despite a mild transition period from barn feeding to pasture, significant effects on reticuloruminal pH values were observed. During barn feeding, the mean reticuloruminal pH value for all of the cows was 6.44 ± 0.14, and the pH values decreased significantly (p pH values increased again (pH 6.25 ± 0.22; pH 6.31 ± 0.17; pH 6.37 ± 0.16). Our results showed that the animals had significantly lowered reticuloruminal pH during the periods of feed transition from barn to pasture feeding. Despite these significant changes, the decrease was not harmful, as indicated by data of feed intake and milk production.

    Full Text Available Background and Aim: Central venous catheters (CVC are important in the management of critically ill patients. Incorrect positioning may lead to many serious complications. Chest radiograph is a convenient means of determining the correct position of the catheter tip. The present study was designed to evaluate the depth of CVC placed through the right and left internal jugular vein (IJV in order to achieve optimum placement of the catheter tip. Materials and Methods: A total of 107 patients in whom CVCs were put through either the right or left IJV through a central approach were included in this prospective study. Catheter tip position was observed in the post procedure chest radiograph. It was considered correct if the tip was just below the carina in the left-sided catheters and just above carina in the right-sided catheters. The catheters were repositioned based on the chest radiographs. The catheter depth leading to optimum tip placement was noted. Results: In males, catheter repositioning was required in 13 of 58 patients (22.41% in the right IJV catheters, whereas in 2 of 13 patients (15.38% in the left IJV catheters. In females, repositioning was required in 12 of 25 patients (48% in the right IJV catheters and 2 of 11 patients (18.18% in the left IJV catheters. Repositioning rate was higher in females (14/36 compared with males (15/71, which was statistically significant ( P = 0.05, 95% CI. Repositioning rates were significantly higher in females (12/25 as compared with males (13/58 in the right IJV catheters ( P = 0.019, 95% CI. Conclusion: By cannulating the IJV through a central approach, the catheters can be fixed at a length of 12-13 cm in males and 11-12 cm in females in the right IJV and at a length of 13-14 cm in males and 12-13 cm in females in the left IJV in order to achieve correct positioning.

    Purpose: It is always a challenge to reconstruct the interstitial catheter for high dose rate (HDR) brachytherapy on patient CT or MR images. This work aims to investigate the feasibility of using the Calypso system (Varian Medical, CA) for HDR catheter reconstruction utilizing its accuracy on tracking the electromagnetic transponder location. Methods: Experiment was done with a phantom that has a HDR interstitial catheter embedded inside. CT scan with a slice thickness of 1.25 mm was taken for this phantom with two Calypso beacon transponders in the catheter. The two transponders were connected with a wire. The Calypso system was used to record the beacon transponders’ location in real time when they were gently pulled out with the wire. The initial locations of the beacon transponders were used for registration with the CT image and the detected transponder locations were used for the catheter path reconstruction. The reconstructed catheter path was validated on the CT image. Results: The HDR interstitial catheter was successfully reconstructed based on the transponders’ coordinates recorded by the Calypso system in real time when the transponders were pulled in the catheter. After registration with the CT image, the shape and location of the reconstructed catheter are evaluated against the CT image and the result shows an accuracy of 2 mm anywhere in the Calypso detectable region which is within a 10 cm X 10 cm X 10 cm cubic box for the current system. Conclusion: It is feasible to use the Calypso system for HDR interstitial catheter reconstruction. The obstacle for its clinical usage is the size of the beacon transponder whose diameter is bigger than most of the interstitial catheters used in clinic. Developing smaller transponders and supporting software and hardware for this application is necessary before it can be adopted for clinical use.

  8. Ethanol causes protein precipitation--new safety issues for catheter locking techniques.

    Gernot Schilcher

    Full Text Available OBJECTIVE: The ethanol lock technique has shown great potential to eradicate organisms in biofilms and to treat or prevent central venous catheter related infections. Following instillation of ethanol lock solution, however, the inherent density gradient between blood and ethanol causes gravity induced seepage of ethanol out of the catheter and blood influx into the catheter. Plasma proteins so are exposed to highly concentrated ethanol, which is a classic agent for protein precipitation. We aimed to investigate the precipitating effect of ethanol locks on plasma proteins as a possible cause for reported catheter occlusions. METHODS: Plasma samples were exposed in-vitro to ethanol (concentrations ranging from 7 to 70 v/v% and heparin lock solutions. In catheter studies designed to mimic different in-vivo situations, the catheter tip was placed in a plasma reservoir and the material contained within the catheter was analyzed after ethanol lock instillation. The samples underwent standardized investigation for protein precipitation. RESULTS: Protein precipitation was observed in plasma samples containing ethanol solutions above a concentration of 28%, as well as in material retrieved from vertically positioned femoral catheters and jugular (subclavian catheters simulating recumbent or head down tilt body positions. Precipitates could not be re-dissolved by dilution with plasma, urokinase or alteplase. Plasma samples containing heparin lock solutions showed no signs of precipitation. CONCLUSIONS: Our in-vitro results demonstrate that ethanol locks may be associated with plasma protein precipitation in central venous catheters. This phenomenon could be related to occlusion of vascular access devices locked with ethanol, as has been reported. Concerns should be raised regarding possible complications upon injection or spontaneous gravity induced leakage of such irreversibly precipitated protein particles into the systemic circulation. We suggest

    Cardiac ablation procedures during electrophysiology interventions are performed under x-ray guidance with a C-arm imaging system. Some procedures require catheter navigation in complex anatomies like the left atrium. Navigation aids like 3D road maps and external tracking systems may be used to facilitate catheter navigation. As an alternative to external tracking a fully automatic method is presented here that enables the calculation of the 3D location of the ablation catheter from individual 2D x-ray projections. The method registers a high resolution, deformable 3D attenuation model of the catheter to a 2D x-ray projection. The 3D localization is based on the divergent beam projection of the catheter. On an individual projection, the catheter tip is detected in 2D by image filtering and a template matching method. The deformable 3D catheter model is adapted using the projection geometry provided by the C-arm system and 2D similarity measures for an accurate 2D/3D registration. Prior to the tracking and registration procedure, the deformable 3D attenuation model is automatically extracted from a separate 3D cone beam CT reconstruction of the device. The method can hence be applied to various cardiac ablation catheters. In a simulation study of a virtual ablation procedure with realistic background, noise, scatter and motion blur an average 3D registration accuracy of 3.8 mm is reached for the catheter tip. In this study four different types of ablation catheters were used. Experiments using measured C-arm fluoroscopy projections of a catheter in a RSD phantom deliver an average 3D accuracy of 4.5 mm.

    Full Text Available Introduction: Central venous catheterization is one of the most common medical procedures and is associated with such complications as misplacement and pneumothorax. Chest X-ray is among good ways for evaluation of these complications. However, due to patient’s excessive exposure to radiation, time consumption and low diagnostic value in detecting pneumothorax in the supine patient, the present study intends to examine bedside ultrasound diagnostic value in locating tip of the catheter and pneumothorax. Materials and methods: In the present cross-sectional study, all referred patients requiring central venous catheterization were examined. Central venous catheterization was performed by a trained emergency medicine specialist, and the location of catheter and the presence of pneumothorax were examined and compared using two modalities of ultrasound and x-ray (as the reference standard. Sensitivity, specificity, and positive and negative predicting values were reported. Results: A total of 200 non-trauma patients were included in the study (58% men. Cohen’s Kappa consistency coefficients for catheterization and diagnosis of pneumothorax were found as 0.49 (95% CI: 0.43-0.55, 0.89 (P<0.001, (95% CI: 97.8-100, respectively. Also, ultrasound sensitivity and specificity in diagnosing pneumothorax were 75% (95% CI: 35.6-95.5, and 100% (95% CI: 97.6-100, respectively. Conclusion: The present study results showed low diagnostic value of ultrasound in determining catheter location and in detecting pneumothorax. With knowledge of previous studies, the search still on this field.   Keywords: Central venous catheterization; complications; bedside ultrasound; radiography;
