    The aim of this study was to compare incidence rates of mechanical and infectious complications associated with central venous catheterization via the internal jugular vein (IJV) versus the subclavian vein (SV) among 45 consecutive patients undergoing orthotopic liver transplantation (OLT) between January 2000 and June 2004. The subjects were divided into two groups according to the site of central venous catheterization (IJV or SV). We recorded each patient's physical characteristics, international normalized ratio (INR), partial thromboplastin time, platelet levels, number of puncture attempts, success/failure of central venous catheterization, duration of catheter placement, occurrence of catheter tip misplacement, arterial puncture, incidence of hematoma or pneumothorax, catheter-related infection, or bacterial colonization of the catheter. Senior staff anesthesiologists performed 22 SV and 23 IJV catheterizations for the 45 OLT procedures. The SV and IVJ groups both had minor coagulation abnormalities with slightly increased INR values at the time of catheterization. There were no significant differences between the groups with respect to success of central venous catheterization (100% for both), numbers of attempted punctures, duration of catheter placement, and incidence rates of mechanical and infectious complications. Both groups showed high frequencies of catheter tip misplacement, with right atrium as the site of misplacement in all cases. Two patients in the IJV group (8.7%) developed hematomas after accidental carotid artery puncture. The results suggest that, when performed by experienced anesthesiologists, central venous catheterization via the SV is an acceptable alternative to IJV catheterization for patients undergoing OLT.

    Full Text Available Eissa Bilehjani,1 Solmaz Fakhari2 1Department of Cardiovascular Anesthesia, Tabriz University of Medical Sciences, Madani Heart Hospital, 2Department of Anesthesiology, Tabriz University of Medical Sciences, Madani Heart Hospital, Tabriz, Iran Abstract: Suprapubic catheterization is an alternative method for urinary drainage that is used when transurethral catheterization fails. 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.

    Full Text Available Central venous catheterization is an invasive procedure commonly preferred for hemodynamic monitorization, total parenteral nutrition, cardiac pacemaker implantation, long-term use of vasoactive or irritating agents and hemodialysis. We present a 19-year-old woman with acute renal failure scheduled for hemodialysis catheterization. A catheter guidewire extending from the right internal jugular vein to the right external iliac vein was detected in the chest X-ray, taken two hours following catheterization after occurrence of arrhythmia and hypotension. Catheteter guidewire was extracted noninvasively without any complications. Most common reasons for this complication are stated to be attention deficits, lack of experience, overtired staff, and inadequate supervision of trainees. In this paper, we discussed this complication’s causes and preventive methods. (Journal of the Turkish Society Intensive Care 2011; 9:64-7

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

    Central venous catheterization using the Seldinger technique is a well known and often used method. On the other hand, there are also well known complications by needle puncture or by indwelling catheter, there are few reports about a guide wire which got hung up around the tricuspid valve. We report a case in which a guide wire got hung up to the chordae tendineae of the tricuspid valve. To insert the AVA 3Xi (Edwards life science Co. Iervine) from the right internal jugular vein, we inserted a guide wire without ease. Resistance appeared when we tried to remove the wire for 20 cm from the inserted state. The X-ray and the transesophageal echocardiography, showed the guide wire in the right ventricle. As actions to be taken, we advanced the central vein catheter of the EXCV catheter kit (Nippon Sherwood Medical Industries Co., Ltd.) to the tip, and a the guide wire was easily removed. There are many reports of the complication by the central venepuncture, but there are few reports about the guide wire which was entrapped in the vicinity of a tricuspid valve. The tip of the guide wire in this case was bent excessively, but the cause of the damage did not become clear by investigation. When a guide wire became hard to withdraw, we should never withdraw a guide wire blindly, but should search a cause and we should use the material which was matched with the cause.

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

    Full Text Available Central venous Catherization (CVC is rarely complicated by pleural effusion. It is usually due to malpositioned catheter. Our patient was a 35-year-old man admitted with Menningoencephalitis.A cervical central vein catheter was placed into his right jugular vein after induction of anaesthesia in Emergency Room. In chest x ray we encountered bilateral pleural effusion and drained it with a chest tube. During following days the patient has daily drainage of almost 1.7 liter of clear yellowish fluid from chest tube. Fluid analysis was not diagnostic. We removed the central vein catheter and plural drainage was stopped. [Natl J Med Res 2015; 5(4.000: 329-331

    Full Text Available Mechanical complications of central venous catheterization (CVC include artery puncture, vein injuries, catheter malposition (CM, pneumothorax, hemothorax, air embolism, subcutaneous hematoma and arrhythmia. This report was aimed to present the case developing hemothorax due to multilumen catheter (MLC malposition following venous perforation which is overlooked during CVC. A 21-year old female patient was planned urgent surgery due to a sharp object injury on the right arm. MLC was inserted to left internal jugular vein (IJV using the seldinger technique in the second attempt. Despite administration of erythrocyte suspension, fluid and noradrenaline infusion through the MLC, patient’s Hct did not increase, hypotension and tachycardia were continued. Catheter was not used and peripheral venous vascular access was used for replacement and infusions. Postoperatively, opacity covering the left hemithorax was detected on the chest radiograph, marked pleural effusion and pneumothorax on the left side was detected on thorax computed tomography. MLC was removed and tube thoracostomy drainage was administered. Hemorrhagic fluid was drained from thorax. Conservative treatment was deemed appropriate since stable vital signs after chest tube application. The complication rate is low and success rate is high in CVC from IJV. Malposition is rare in CVC application from right IJV than in CVC application from left IJV. There is a sharp curve in CVC from the left IJV, which frequently leads to malposition of the MLC. CM should be suspected with no aspiration of blood through catheter or aspiration of another substance such as air, chylous fluid, etc. and non-pulsatile blood flow. If dyspnea, tachycardia, tachypnea, hypotension and desaturation develop after catheter administration we should be alert.

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

    Full Text Available Background: Nothing can be more difficult, time consuming and frustrating than obtaining vascular access in critically ill pediatric patient1 .Central venous catheters are widely used in the care of critically ill patients. Methodology: This paper reviews our experience with central lines in 28 critically ill patients including neonates and non-neonates, in a study period of October 2008 to October 2009. Of the total 28 patients, central venous catheterizations was more in those who were more than a month age and of female sex. Results: The route of insertion was femoral in approximately 89% of our patients and insertion was successful in 24 patients. The most common indication we observed for catheter use was, venous access in shock (37.1% in neonates and for monitoring the central venous pressure (32% in non neonate patients of ARDS with pulmonary edema and Shock. The central line was removed in majority of patients (60% within 24-48hrs of insertion and was kept for maximum of six days in just one patient. Organism most frequently isolated was Acinetobacter. Recommendations made include, use strict aseptic measures by restricted number of skilled operators while inserting and during maintaining central line, routine confirmatory x-ray or fluoroscopy to check the position of central line before catheter use, if possible, use for central pressure monitoring recommended. Conclusion: We concluded that central venous catheterization is a safe and effective measure so we recommend timely and judicious use of percutaneous central venous catheter in paediatric critically ill patients of PICU and NICU.

    To determine the usefulness and safety of radiological placement of a central venous catheter by prospectively comparing the results of interventional radiology and blind surgery. For placement of a central venous catheter, the blind surgical method was used in 78 cases (77 patients), and the interventional radiological method in 56 cases (54 patients). The male to female ratio was 66:68, and the patients' mean age was 48 (range, 18-80) years. A tunneled central venous catheter was used in 74 cases, and a chemoport in 60. We evaluated the success and duration of the procedures, the number of punctures required, and ensuing complications, comparing the results of the two methods. The success rates of the interventional radiological and the blind surgical procedure were 100% and 94.8%, respectively. The duration of central catheterization was 3-395 (mean, 120) day, that of chemoport was 160.9 days, and that of tunneled central venous catheter was 95.1 days. The mean number of punctures of the subclavian vein was 1.2 of interventional radiology, and 2.1 for blind surgery. The mean duration of the interventional radiology and the blind surgical procedure was, respectively, 30 and 40 minutes. The postprocedure complication rate was 27.6% (37 cases). Early complications occurred in nine cases (6.7%): where interventional radiology was used, there was one case of hematoma, and blind surgery gave rise to hematoma (n=2), pneumothorax (n=2), and early deviation of the catheter (n=4). Late complications occurred in 32 cases (23.9%). Interventional radiology involved infection (n=4), venous thrombosis (n=1), catheter displacement (n=2) and catheter obstruction (n=5), while the blind surgical procedure gave rise to infection (n=5), venous thrombosis (n=3), catheter displacement (n=4) and catheter obstruction (n=8). The success rate of interventional radiological placement of a central venous catheter was high and the complication rate was low. In comparison with the blind

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

    Two complications of central venous catheterization (CVC), iatrogenic pneumothorax and central line-associated bloodstream infection (CLABSI), have dedicated International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Despite increasing use of ICD-9-CM codes for research and pay-for-performance purposes, their validity for detecting complications of CVC has not been established. Complications of CVCs placed between July 2010 and December 2011 were identified by ICD-9-CM codes in discharge records from a single hospital and compared with those revealed by medical record abstraction. The ICD-9-CM code for iatrogenic pneumothorax had a sensitivity of 66.7%, specificity of 100%, positive predictive value (PPV) of 100%, and negative predictive value (NPV) of 99.5%. The ICD-9-CM codes for CLABSI had a sensitivity of 33.3%, specificity of 99.0%, PPV of 28.6%, and NPV of 99.2%. The low sensitivity and variable PPV of ICD-9-CM codes for detection of complications of CVC raise concerns about their use for research or pay-for-performance purposes.

    The most important targets of hospital-acquired infection control are to reduce the incidence of surgical-site, catheter-related, and ventilator-associated infections. In this report, we address previously presented infection-control strategies for central venous (CV) line catheterization, using a CV catheter-related infection surveillance system. Data concerning CV catheter insertion were collected from all facilities in our 650-bed hospital, excluding the operating and hemodialysis wards. Collected data included the insertion method, purpose, length of catheter inserted, duration of catheterization, infection rate, and complication rate. Catheter-related infection was diagnosed based on bacteriological examinations from blood cultures. The total number of catheterizations was 806 a year, and average duration of catheterization was 9.8 days. The purpose of catheterization was nutritional support in 210 cases, hemodialysis in 96 cases, cardiac support in 174 cases, and other treatments in 260 cases. In 66 cases, the purpose of CV catheter was not specified. The rate of positive cultures was 7.1%, and complications other than infection occurred in 0.5%. The main causative organisms were methicillin-resistant Staphylococcus aureus (MRSA) in 38.6%, coagulase-negative Staphylococcus epidermidis (CNS) in 33.3%, and S. aureus in 12.3% of infections. Infection rates were 3.8 per 1000 catheter-days in subclavian, 6.1 in jugular, and 15.7 in femoral vein catheterization. In high-risk departments (intensive care unit [ICU] and emergency departments) the infection rate was 5.4 for subclavian and 10.2 for jugular catheterization, whereas it was 3.6 for subclavian and 4.6 for jugular catheterization in noncritical-care departments. Considering complications such as pneumothorax, CV catheterization of the jugular vein is recommended in certain situations.

This study aims to evaluate the teaching and supervision of junior residents in central venous catheterization (CVC by resident-teachers. Methods All PGY-1 internal medicine residents at two Canadian academic institutions were invited to complete a survey on their CVC experience, teaching, and supervision prior to their enrolment in a simulator CVC training curriculum. Results Of the 69 eligible PGY-1 residents, 32 (46% consenting participants were included in the study. There were no significant baseline differences between participants from the two institutions in terms of sex, number of ICU months completed, previous CVC training received, number of CVCs observed and performed. Only 16 participants (50% received any CVC training at baseline. Of those who received any training, 63% were taught only by senior resident-teachers. A total of 81 CVCs were placed by 17 participants. Thirty-two CVCs (45% were supervised by resident-teachers. Conclusions Resident-teachers play a significant role both in the teaching and supervision of CVCs placed by junior residents. Educational efforts should focus on preparing residents for their role in teaching and supervision of procedures.

    Central venous catheterization is a routine vascular access procedure; however, it may be associated with life-threatening complications such as arterial puncture, leading to pseudoaneurysm formation. We report a case of a 41-year-old female that developed an iatrogenic left subclavian pseudoaneurysm complicating the attempt of left internal jugular vein cannulation for temporary hemodialysis therapy. The patient underwent urgent endovascular treatment with deployment of covered stent into the left subclavian artery (SCA) after embolization of the origin of the left internal mammary artery with Amplatzer Vascular Plug 4. The patient's recovery was unremarkable. Follow-up till 24 months reveals total exclusion of the pseudoaneurysm of the left SCA with patency of the distal branches.

    The safe and successful performance of a central venous catheterization (CVC) requires a specific knowledge of anatomy in addition to a working knowledge. Misunderstanding the anatomy may result in failure or complications. This review aims to aid understanding of the anatomical framework, pitfalls, and complications of CVC of the subclavian (SCV). CVC is common practice amongst surgeons, anesthesiologists, and emergency room physicians during the preparations for major surgical procedures such as open-heart surgery, as well as, for intensive care monitoring and rapid restoration of blood volume. Associated with this technique are certain anatomical pitfalls and complications that can be successfully avoided if one possesses a thorough knowledge of the contraindications, regional anatomy, and rationale of the technique.

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

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

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

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

    A case of inadvertent thoracic duct puncture during right axially central venous cannulation is reported. The catheterization was performed under the real time ultrasound guidance technique and the coronal view image was continuously displayed. After confirming the feelings of venous puncture, clear yellow fluid was aspired into the connected syringe to the needle. Initially, an accidental thoracic puncture with subsequent pleural fluid aspiration was suspected;however, no finding of pleural effusion was observed with ultrasound imaging and computed tomography. Thus, an accidental thoracic duct puncture and the subsequent lymph fluid aspiration were suspected. Even in a right side approach for central venous catheterization, thoracic duct injury might ensure.

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

    This paper introduced the application of electrocardiogram in central venous catheterization for 326 patients with tumors and its nursing care. With the change of P wave of electrocardiography, the central venous catheter tip could be inspected, which contributed to the improvement of success rate and there was less radioactive pollution from X-ray and less local hemorrhage in puncture point. All catheters were successfully placed and the success rate was improved. Since no change of P wave was detected, the central venous catheter was placed with X-ray positioning among six patients. Oozing lasted in puncture point among 78 patients for 2 to 3 days and stopped after treatment. The communication between patients and nurses played a critical part in the whole process. Successful completion of chemotherapy was witnessed in all patients in the study.%  总结326例肿瘤患者在中心静脉置管过程中应用心电导联技术的护理经验。通过穿刺过程中加强护患沟通,利用心电图P波改变及时调整导管尖端位置,改变穿刺方法,提高了穿刺成功率,减少了X线的放射性污染及穿刺点的局部出血。本组326例患者均成功置管,1次置管成功率相比传统中心静脉置管提高了约4%。本组6例患者在未见P波改变情况下,改用 X线定位;78例患者穿刺处少量渗血持续2~3 d,经积极处理后,出血停止。所有病例均顺利完成化疗。

    Objective: To study the incidence of immediate complications associated with percutaneous central venous catheterization. Materials and Methods: A total of 103 central venous catheters were inserted in 70 children over a period of 18 months, governed by a uniform protocol. Sixty-three percent of the catheters were inserted in neonates, 23.3% in infants and 13.6% in children between 1 and 12 years of age. Statistical Analysis Used: Software SPSS version 15. Results: There were a total of 41 insertion-related immediate complications, of which 75.6% were in neonates. Neonatal age, hemodynamic instability and more number of attempts to catheterize the vein had a higher risk of insertion-related problems. There was no mortality directly as a result of the procedure. Conclusion: In our practice, it was observed that complications were fewer with increasing familiarity with the procedure. Hence, percutaneous central venous catheterization is a safe procedure when performed in experienced hands. PMID:22121313

    The guidelines to prevent central venous catheter related bloodstream infections (CVCBSI) of the Centers for Disease Control and Prevention (CDC) of 2002, Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias/ Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica (SEMICYUC/SEIMC) of 2004, and the recently published guidelines of the Society for Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA(IDSA) of 2008 have recommended using the subclavian vein and avoiding the use of the femoral vein. They also recommend considering the use of antiseptic- or antimicrobial-impregnated CVCs for hospital units or groups of patients with a high incidence of CVCBSI. When implementing these guidelines, two questions could be asked: 1) Could the abuse of the subclavian vein and avoiding the use of the femoral vein imply a decrease in the incidence of CVCBSI, but an increase in the rate of mechanical complications as pneumothorax and/or hemothorax? 2) Couldn't antimicrobial-impregnated CVCs be used to prevent CVCBSI when the femoral venous access is used?

    Central venous catheterization (CVC)-related venous thrombosis is a common but serious clinical complication, thus prevention and treatment on this problem should be extensively investigated. In this research, we aimed to investigate the incidence rate of CVC-related venous thrombosis in senile patients and give a further discussion on the related risk factors and predictors. A total of 324 hospitalized senile male patients subjected to CVC were selected. Retrospective investigation and analysis were conducted on age, underlying diseases, clinical medications, catheterization position and side, catheter retention time, and incidence of CVC-related venous thrombosis complications. Basic laboratory test results during catheterization and thrombogenesis were also collected and analyzed. Among the 324 patients, 20 cases (6.17%) of CVC-related venous thrombosis were diagnoseds. The incidence rate of CVC-related venous thrombosis in subclavian vein catheterization was significantly lower than that in femoral vein catheterization (Pvenous thrombosis history (Prisk factors or predictors of CVC-related venous thrombosis in senile male patients. Subclavian vein catheterization was the most appropriate choice among senile patients to decrease the incidence of CVC-related venous thrombosis. Previous venous thrombosis history, high lactate dehydrogenase level, low HDL level, and low albumin level were important risk factors in predicting CVC-related venous thrombosis.

    Central venous catheterization in pediatric patients has, among other risks, flebitis and thrombosis, and finally occlusion of the superior and inferior venae cavae, making long-term catheterization and multiple venous cutdown more difficult. Use of the internal mammary vein might be an alternative procedure to provide sure and easy access to the central venous circulation. The authors report on a patient with multiple venous cutdown and thrombosis of the inferior vena cava, in whom the internal mammary vein was used for placement of a vascular device. The procedure is technically easy, and no special positioning of the patient is required.

    Full Text Available OBJETIVO: O objetivo do estudo foi verificar a freqüência de sucesso e de complicações da punção percutânea da veia subclávia em crianças e adolescentes e identificar os fatores associados. MÉTODOS: Estudou-se uma série de 204 punções percutâneas da veia subclávia, utilizando cateter de cloreto de polivinil (Intracath® em crianças e adolescentes no Instituto Materno-Infantil Professor Fernando Figueira no período de 01/12/2003 a 30/04/2004. Foram analisadas variáveis relacionadas ao paciente, como idade, e relacionadas ao procedimento, como sucesso, tipo de anestesia, complicações, quem realizou e número de tentativas de punção. RESULTADOS: Houve sucesso em 89,2% das punções. O percentual de sucesso foi significantemente maior nas punções realizadas com a criança sob narcose (94%. Cerca de 43,2% das punções evoluíram com complicações relacionadas à inserção do cateter; no entanto, complicações de maior gravidade ocorreram em apenas 3,5% dos casos. Houve um maior número de complicações nas punções realizadas pelo residente do primeiro ano (58,8%, sendo que este realizou um percentual de procedimentos significativamente maior em crianças menores de 1 ano e com a realização de um maior número de tentativas no mesmo paciente. CONCLUSÕES: A realização do procedimento com o paciente sob narcose mostrou aumentar a chance de sucesso. Há maior chance de complicações relacionadas à inserção do cateter em punções de veia subclávia realizadas por médicos menos experientes, sendo prudente selecionar as punções em situações de maior risco para cirurgiões com maior experiência no procedimento.OBJECTIVE: The objective of this study was to investigate the rates of success and of complications of percutaneous subclavian central venous catheterization in children and adolescents and to identify factors associated with them.

    Central venous catheterization is a common procedure for critically ill patients. Like all procedures, it has its complications, one of which is thrombosis. Reports of thrombosis are commoner among cancer patients. We present a 37 year old non cancer patient who developed thrombi in both right and left internal jugular veins, 10 and 13 days respectively after insertion of central venous catheter. This was detected by ultrasound scans of the neck while attempting re-cannulation for parenteral feeding. She also had left lower limb deep venous thrombosis, confirmed by doppler scan, which was managed with low molecular weight heparin and warfarin. The patient was subsequently treated with streptokinase. A repeat scan of the internal jugular veins 4 days after thrombolysis revealed a reduction in size of the thrombi. Symptoms of deep venous thrombosis improved and she was transferred to the wards where she made remarkable improvement. This case illustrates the potential usefulness of ultrasound guided-central line insertion in patients who have had central venous lines inserted previously in order to detect thrombi.

    Full Text Available Background: In recent years, venous access via middle approach with the technique described by English has been frequently used, leading to lower risk of pneumothorax and arterial puncture. In addition, it is easy to perform. Objective: to characterize the performance of central venous access via the middle approach to the internal jugular vein using the Seldinger guidewire in patients with hematologic diseases and/or anticoagulant therapy. Methods: a descriptive study was conducted from January to December 2009 in the Surgical Unit of the Dr. Gustavo Aldereguía Lima University General Hospital in Cienfuegos. Central venous access via middle approach using the technique described by English was performed in 47 patients suffering from hematologic diseases. Variables analysed were: number of attempts, indications and complications. Results: 43 central venous catheterizations were successful (91.48 %, 35 of them were achieved in the first attempt. The use of cytostatics was indicated in more than half of the cases (55.31 %. Complications were observed in 5 patients; arterial puncture was the most common (6.38 %. Conclusions: central venous access via the middle approach using the Seldinger guidewire is a suitable option for patients with hematologic diseases. It minimizes complications in patients treated with anticoagulants. In general, it is easily accessible and has a high success rate.

    Full Text Available We report the occurrence of a bilateral pneumothoraces after unilateral central venous catheterization of the right subclavian vein in a 70-year-old patient. The patient had no history of pulmonary or pleural disease and no history of cardiothoracic surgery. Two days earlier, she had a median laparotomy under general and epidural anaesthesia. Prior to the procedure, the patient was hemodynamically stable and her transcutaneous oxygen saturation was 97% in room air. We punctured the right pleural space before cannulation of the right subclavian vein. After the procedure, the patient slowly became hemodynamically instable with respiratory distress. A chest radiograph revealed a complete left-side pneumothorax and a mild right-side pneumothorax. The right-side pneumothorax became under tension after left chest tube insertion. The symptoms finally resolved after insertion of a right chest tube. After a diagnostic work-up, we suspect a congenital “Buffalo chests” explaining bilateral pneumothoraces and a secondary tension pneumothorax.

    Introduction: Determining the proper angle for inserting central venous catheter (CV line) is of great importance for decreasing the complications and increasing success rate. The present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization. Methods: In the present case series study, candidate patients for catheterization of the right internal jugular vein under guidance of ultrasonography were studied. At the time of proper placing of the catheter, photograph was taken and Auto Cad 2014 software was used to measure the angles of the needle in the sagittal and axial planes, as well as patient’s head rotation. Result: 114 patients with the mean age of 56.96 ± 14.71 years were evaluated (68.4% male). The most common indications of catheterization were hemodialysis (55.3%) and shock state (24.6%). The mean angles of needle insertion were 102.15 ± 6.80 for axial plane, 36.21 ± 3.12 for sagittal plane and the mean head rotation angle was 40.49 ± 5.09. Conclusion: Based on the results of the present study it seems that CV line insertion under the angles 102.15 ± 6.80 degrees in the axial plane, 36.21 ± 3.12 in the sagittal plane and 40.49 ± 5.09 head rotation yield satisfactory results.

    To evaluate the usefulness of ultrasonography for diagnosis of portal vein thrombosis (PVT) associated with the umbilical venous catheterization (UVC). We reviewed the abnormal ultrasonography of 54 patients with UVC. We observed echogenic thrombus in the portal vein by ultrasonography which has a 5-10 MHz linear transducer. We evaluated the frequency of PVT, the relationship between PVT and duration of UVC, and the location of catheter tip (Group I (n=41): above the diaphragm, Group II (n=9): between the diaphragm and the liver, Group III (n=4): below the liver), the location of thrombus on US, and the change of PVT on the follow-up ultrasonography. PVT was identified in the 7 neonates (13%) among the 54 neonates with UVC. The frequency of PVT was 5% on group I, 45% on group II and 25% on group III. The 6 cases among the 7 cases(86%) of PVT were localized to the umbilical portion of the left portal vein, and there were completely resolved (n=4) or regressed (n=1) on the follow-up ultrasonography(n=5). Remaining one case of PVT was located in the right, left, and main portal veins with collateral formation, and cavernous transformation occurred on the follow-up. Most PVTs by UVC are localized to the umbilical portion of left portal vein. Ultrasonography is a useful modality to diagnose PVT by UVC.

    Central venous line placement is a standard procedure in critical care and peri-operative medicine. This procedure can be associated with severe complications. In contrast to the landmark technique, ultrasound-guided punctures can significantly reduce the rate of complications. Patients with a high risk for difficult vascular access include critical care and emergency patients as well as patients on anticoagulation medication and dialysis. Placement of central venous catheters can be difficult in ventilated patients and if there has been prior surgery in the puncture area. In children and small infants central venous access can also be challenging due to the anatomical relationship in the head and neck region. Puncture techniques are explained briefly by means of ultrasound anatomy. Typical ultrasonographic images visualize pathological findings in order to identify dangers and complications in central venous catheterization.

    Full Text Available Blood stream infections related to central venous catheterization are one of the major device-associated infections reported. Patients admitted in critical care units requiring central venous catheterization and presenting with signs of septicemia during catheterization period were investigated for catheter-related blood stream infections (CRBSI. The CRBSI rate was 9.26 per 1000 catheter days in general with highest rate in neonatal intensive care unit (27.02/1000 days. Site of insertion of catheter and duration of catheterization did not show the influence on the CRBSI rate. Coagulase-negative Staphylococci were the predominant cause. Mortality of 33% was observed in patients with CRBSI. Since central venous catheters are increasingly being used in the critical care, regular surveillance for infection associated them are essential.

  11. Radiographic mislead: apparent arterial placement of subclavian central venous catheter due to mediastinal shift

    2014-01-01

    Full Text Available Optimal placement of central venous catheters (CVC is essential for accurate monitoring of central venous pressure (CVP in major surgeries and ensuring long-term use of the catheter for managing the critically ill patient. Accidental subclavian artery catheterization is one of the most serious complications of the procedure. Radiography is commonly used to ensure optimal placement of CVC tip and rule out subclavian artery catheterization in the absence of Doppler ultrasound and a pressure transducer. We present a case of a haemodynamically unstable and hypoxaemic patient with mediastinal shift, in which the anaesthesiologist was in a dilemma about the arterial placement of the right subclavian CVC. The CVC crossing the midline due to mediastinal shift gave the false impression of it being placed in subclavian artery rather than the vein. Subsequently, it was proved to be correctly placed in the subclavian vein.

    We present a 6-year-old girl with acute lymphoblastic leukemia who demonstrated on chest X-ray a radiopacity in the superior vena cava after removal of an implanted venous access device. This radiopacity was initially thought to be a retained catheter fragment. On review of previous imaging, we were able to document the temporal development of a calcified catheter cast as distinct from the catheter. This case represents a rare consequence of central venous catheterization in children. Knowledge of this finding as a possible complication may help avoid performance of unnecessary follow-up imaging or invasive procedures.

    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.

  14. Central Venous Catheter-Related Hydrothorax

    Directory of Open Access Journals (Sweden)

    Se Hun Kim

    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.

    Nawa,Sugato

    1989-08-01

    Full Text Available Changes in the hemodynamics of six patients having received Fontan-like operations were closely observed during the first 48 h after the operation. Catheterization studies and simultaneous angiocardiography were also performed before and after the operation. Hemodynamic derangement was particularly severe during the first 24 h postoperatively as indicated by a low cardiac output of less than 2.01/min/m2, which persisted in spite of very high central venous pressure. Furthermore, the central venous pressure needed to re-establish the circulation soon after the Fontan procedure significantly correlated with the angiocardiographically assessed preoperative size of distal pulmonary arteries. Accordingly, the preoperative evaluation of the distal pulmonary arterial size is very important, that provides a good guide-line for the degree of circulatory volume expansion necessary to elevate the central venous pressure and to sustain the circulation in the early postoperative period.

    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.

    We experienced a case of deep vein thrombosis after spine surgery in the prone position with a central venous catheter (CVC). Posterior lumbar interbody fusion was performed on a 73-year-old female patient who was diagnosed with spinal stenosis. Accordingly, in the operation room under general anesthesia, two-lumen CVC were inserted into the left subclavian vein. The surgery was performed in the prone position with a Wilson frame. On the next day, there was a sudden occurrence of severe edema in the patient's left arm. By ultrasonography and computed tomography scanning, extensive deep vein thrombosis was observed in the left subclavian vein. The existence of a factor affecting blood flow such as the prone position may increase the risk of thrombus formation. Therefore, careful perioperative evaluation should be implemented.

    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.

    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.

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

    The use of central venous catheters (CVCs) in children is escalating, which is likely linked to the increased incidence of pediatric venous thromboembolism (VTE). In order to better understand the specific risk factors associated with CVC-VTE in children, as well as available prevention methods, a literature review was performed. The overall incidence of CVC-VTE was found to range from 0 to 74%, depending on the patient population, CVC type, imaging modality, and study design. Throughout the available literature, there was not a consistent determination regarding whether a particular type of central line (tunneled vs. non-tunneled vs. peripherally inserted vs. implanted), catheter material, insertion technique, or insertion location lead to an increased VTE risk. The patient populations who were found to be most at risk for CVC-VTE were those with cancer, congenital heart disease, gastrointestinal failure, systemic infection, intensive care unit admission, or involved in a trauma. Both mechanical and pharmacological prophylactic techniques have been shown to be successful in preventing VTE in adult patients, but studies in children have yet to be performed or are underpowered. In order to better determine true CVC-VTE risk factors and best preventative techniques, an increase in large, prospective pediatric trials needs to be performed.

    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.)

    To evaluate factors which affect the longevity of tunneled central venous catheters (T-CVCs). A retrospective study was conducted on 363 T-CVCs. We evaluated the relevant factors affecting the longevity of the T-CVCs, such as age, gender, indication for catheterization, site of entry vessel, diameter and type of T-CVC, catheter tip position, and underlying diseases. Of the 363 T-CVCs which had been inserted, 331 (91%) were placed through the right internal jugular vein (RIJV). The catheter tip position was the strongest predictor for the longevity of the T-CVC. The short limb of the catheter tip placed either at the cavoatrial junction (CA junction) or below the lower margin of the right main bronchus had a good prognosis. The vessel through which the T-CVC was placed significantly influenced the longevity of the T-CVC; the RIJV was associated with better results than the left internal jugular vein. Also, a split-type catheter was significantly associated with a better result. A two distinct and separate type T-CVC placed through the RIJV in which the short limb catheter tip position was at the level of the CA junction, significantly increased the longevity of T-CVCs.

    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.

    Introduction The lack of suitable veins in children with critical central venous access requirements is a major obstacle to optimal care and is potentially life-threatening. We present outcomes following the use of vein-preserving (VP) surgical techniques, notably the sheath exchange for tunneled lines (SETL). Materials and Methods A retrospective, single observer analysis of a prospectively maintained departmental logbook as well as the medical records of patients. Two broad groups of central line replacements were identified; those inserted following removal of a previous line and a traditional "plastic-free" (PF) period and those exchanged without such an interval. Results Overall, 19 lines were directly exchanged during the study period and compared with 34 inserted after a PF period. Similar catheter life spans and infection rates were demonstrated in each group; 125 (range, 78-173) days in VP exchanges versus 122 (range, 70-175) days in PF replacements (p = 0.41). Line Sepsis resulting in removal or change of line occurred at 103 (range, 60-147) days in VP group versus 104 (range, 45-164) days in PF (p = 0.73). Conclusion For children with critical venous access requirements, direct line exchange procedures are a robust and reproducible means of vein preservation. The outcomes compare favorably with those following the more traditional removal, a PF period and reinsertion.

    Objective: To investigate the clinical presentation of dislodged totally implantable central venous access system (central venous port-catheter) fragments and the efficacy and safety of percutaneous retrieval of them in our hospital. Materials and methods: Ninety-two cancer patients, mean age of 53.8 years old with 51.1% male, were enrolled from January 2005 to March 2007. They were referred to our catheterization laboratory for retrieval of fractured central venous port-catheter in our hospital. All patients were followed in the outpatient department for at least 1 month after surgical insertion. The characteristics of disrupted central venous port-catheter were recorded. The procedure-related clinical condition was evaluated. Results: The most common presentation of central venous port-catheter dislodgement is irrigation resistance to infusion (51/92). The most common location of fractured fragments is between superior vena cava and right atrium (i.e. proximal end remained in superior vena cava and distal end in right atrium) (22/92). The most common fracture site of the catheter is at the anastomosis between injection port and catheter (77/92). The retrieval set used mostly is loop snare. The success rate of the percutaneous retrieval of dislodged fragment was 97.8% and the complication rate was 3.3% only. Conclusion: The faulty connection between catheter and injection port contributes mainly to dislodgement of central venous port-catheter. Percutaneous retrieval of dislodged catheter is a highly successful, safe and efficient method.

    Injuries to blood vessels near the heart can quickly become life-threatening and include arterial injuries during central venous puncture, which can lead to hemorrhagic shock. We report 6 patients in whom injury to the subclavian artery and vein led to life-threatening complications. Central venous catheters are associated with a multitude of risks, such as venous thrombosis, air embolism, systemic or local infections, paresthesia, hemothorax, pneumothorax, and cervical hematoma, which are not always immediately discernible. The subclavian catheter is at a somewhat lower risk of catheter-associated sepsis and symptomatic venous thrombosis than approaches via the internal jugular and femoral veins. Indeed, access via the subclavian vein carries a substantial risk of pneumo- and hemothorax. Damage to the subclavian vein or artery can also occur during deliberate and inadvertent punctures and result in life-threatening complications. Therefore, careful consideration of the access route is required in relation to the patient and the clinical situation, to keep the incidence of complications as low as possible. For catheterization of the subclavian vein, puncture of the axillary vein in the infraclavicular fossa is a good alternative, because ultrasound imaging of the target vessel is easier than in the subclavian vein and the puncture can be performed much further from the lung.

    Full Text Available Introduction: Determining the proper angle for inserting central venous catheter (CV line is of great importance for decreasing the complications and increasing success rate. The present study was designed to determine the proper angle of needle insertion for internal jugular vein catheterization. Methods: In the present case series study, candidate patients for catheterization of the right internal jugular vein under guidance of ultrasonography were studied. At the time of proper placing of the catheter, photograph was taken and Auto Cad 2014 software was used to measure the angles of the needle in the sagittal and axial planes, as well as patient’s head rotation. Result: 114 patients with the mean age of 56.96 ± 14.71 years were evaluated (68.4% male. The most common indications of catheterization were hemodialysis (55.3% and shock state (24.6%. The mean angles of needle insertion were 102.15 ± 6.80 for axial plane, 36.21 ± 3.12 for sagittal plane and the mean head rotation angle was 40.49 ± 5.09. Conclusion: Based on the results of the present study it seems that CV line insertion under the angles 102.15 ± 6.80 degrees in the axial plane, 36.21 ± 3.12 in the sagittal plane and 40.49 ± 5.09 head rotation yield satisfactory results.

    Choi, Yong Sun; Park, Ji Young; Kwak, Young Lan; Lee, Jong Wha

    2011-01-01

    We present a case of inadvertent arterial insertion of a central venous catheter, identified during a pericardiectomy procedure after observing abrupt changes in pressure waveform and confirmed via arterial blood gas analysis and transesophageal echocardiography. Central venous pressure measurement was initially 20 mmHg in supine, and then elevated to 30-40 mmHg in right lateral decubitus, presumably resulting from constrictive physiology of pericarditis. The pressure waveforms, however, abruptly changed from a venous to an arterial waveform during surgery. When visual discrimination between arterial and venous blood regurgitation is unreliable, anesthesiologists should confirm that using all the available methods one has on the scene, especially after at least two unsuccessful attempts or in patients with advanced age or clinical conditions resulting in jugular venous dilation. To prevent arterial catheterization, one should limit the leftward rotation of the head by <40° and consider using ultrasound-guided method after more than two unsuccessful attempts.

    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 Central venous catheterization is of common practice in intensive care units; despite representing an essential device in various clinical circumstances, it represents a source of complications, sometimes even fatal, related to its management. We report the removal of a central venous catheter (CVC that had been wrongly positioned through left internal jugular vein. The vein presented complete thrombosis at vascular ultrasonography. An echocardiogram performed 24 hours after CVC removal showed the presence, apparently unjustified, of microbubbles in right chambers of the heart. A neck-thorax CT scan showed the presence of air bubbles within the left internal jugular vein, left innominate vein, and left subclavian vein. A vascular ultrasonography, focused on venous catheter insertion site, disclosed the presence of a vein-to-dermis fistula, as portal of air entry. Only after air occlusive dressing, we documented echographic disappearance of air bubbles within the right cardiac cavity. This report emphasizes possible air entry even many hours after CVC removal, making it mandatory to perform 24–72-hour air occlusive dressing or, when inadequate, to perform a purse string.

    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.

    Full Text Available Background Malfunctions of totally implantable central venous ports (TICVPs have become a problem, as the usage of TICVPs has increased enormously. Objectives This study evaluated factors related with catheter malfunctions of TICVPs. Patients and Methods Between January 2010 and June 2012, 1,740 TICVPs in 1,740 patients (874 men and 866 women with an average age of 57.7 ± 12.8 years (range: 15 - 91 years were implanted by an interventional radiology team at our institute. Catheter malfunctions were retrospectively analyzed. In the prospective study, we randomly allocated 176 patients to two kinds of TICVPs in a 1:1 assignment ratio. The primary outcome was the malfunction of TICVPs. Results In the retrospective study, the 32 malfunctioning TICVPs were caused by fibrin sheath formations (n = 15, chamber thrombosis (n = 8, TICVP rotation (n = 5, catheter migration (n = 2, and blood clots within the catheters (n = 2. Multivariate analysis showed that being female was a significant factor for poor patency rates of TICVPs (hazard ratio: 5.06; 95% confidence interval (CI 1.32 - 19.46, P = 0.018. In the prospective study, two chamber thromboses occurred in Celsite® (n = 1 and Humanport® (n = 1. The primary patency rates of both Celsite® and Humanport® were 98.9% at 6 months, respectively. Conclusion Our data suggest that catheter malfunctions of TICVPs are more common in females than males. The incidence of TICVP malfunctions does not differ between the two devices (Celsite® vs. Humanport®.

    Full Text Available A central venous catheter (CVC is inserted for measurement of haemodynamic variables, delivery of nutritional supplements and drugs and access for haemodialysis and haemofiltration. Catheterization and maintenance are common practices and there is more to the technique than routine placement as evident when a procedure-related complication occurs. More than 15% of the patients who receive CVC placement have some complications and infectious endocarditis involving the tricuspid valve is a rare and serious complication with high morbidity and mortality. Overenthusiastic and deep insertion of the guide wire and forceful injection through the CVC may lead to injury of the tricuspid valve and predispose to bacterial deposition and endocarditis. We report a case of tricuspid valve endocarditis, probably secondary to injury of the anterior tricuspid leaflet by the guide wire or the CVC that required open heart surgery with vegetectomy and repair of the tricuspid valve.

    Objective: To evaluate dialysis history, imaging findings and outcome of endovascular treatment in six patients with central venous stenosis without a history of previous catheter placement. Material and methods: Between April 2000 and June 2004, six (10%) of 57 haemodialysis patients had stenosis of a central vein without a previous central catheter placement. Venography findings and outcome of endovascular treatment in these six patients were retrospectively evaluated. Patients were three women (50%) and three men aged 32-60 years (mean age: 45 years) and all had massive arm swelling as the main complaint. The vascular accesses were located at the elbow in five patients and at the wrist in one patient. Results: Three patients had stenosis of the left subclavian vein and three patients had stenosis of the left brachiocephalic vein. The mean duration of the vascular accesses from the time of creation was 25.1 months. Flow volumes of the vascular access were very high in four patients who had flow volume measurement. The mean flow volume was 2347 ml/min. One of three patients with brachiocephalic vein stenosis had compression of the vein by the brachiocephalic artery. All the lesions were first treated with balloon angioplasty and two patients required stent placement on long term. Number of interventions ranged from 1 to 4 (mean: 2.1). Symptoms resolved in five patients and improved in one patient who had a stent placed in the left BCV. Conclusion: Central venous stenosis in haemodialysis patients without a history of central venous catheterization tends to occur or be manifested in patients with a proximal permanent vascular access with high flow rates. Balloon angioplasty with or without stent placement offers good secondary patency rates in mid-term.

    To evaluate the efficacy and safety of placement of a central venous catheter with infusion port into the superior vena cava. Central venous catheters with a infusion port were implanted in 21 patients (M:F=4:17, age range:15-63, mean age: 41) diagnosed as suffering from breast cancer (n=9), lymphoma (n=7), thymoma (n=2) rhabdomyosarcoma(n=2) and rectal cancer (n=1). The per(n=9), lymphoma(n=7), thymoma (n=2) rhabdomyosarcoma (n=2) and rectal cancer (n=1). The peripheral portion of the subclavian vein was punctured under fluoroscopic guidance during injection of contrast media at the site of the ipsilateral peripheral vein (20 cases) and under ultrasonographic guidance (1 case). 9.6F central venous catheters placed in the superior vena cava via the subclavian vein and the connected infusion ports were implanted in the subcutaneous pocket near the puncture site of the right anterosuperior chest wall. Radiologic placement under fluoroscopic guidance of a central venous catheter with a infusion port is easy, safe and useful for patients requiring long-term venous access.

    Long lines can be inserted centrally or peripherally through patent veins into the central venous system down to the atrial caval junction. Traditionally surgeons, anesthetists, cardiologists and more recently interventional radiologists have been placing them using vein cutdown or percutaneous needle puncture techniques. Typical candidates for implanted venous catheters are cancer patients undergoing long-term chemotherapy. The most important issues, in addition to the patency of central veins and the history of previous indwelling catheters, pacewires or venous thrombosis, are the patient's performance status, body mass index, medical history and respiratory status, and the relevant technique. The present article will give an overview of the radiological and surgical implantation techniques and will highlight the impact of imaging means on the technical feasibility, assessment and treatment of device-related complications.

    Central venous occlusive disease (CVD) is a common concern among the hemodialysis patient population, with the potential to cause significant morbidity. Endovascular management of CVD, comprising percutaneous balloon angioplasty and bare-metal stenting, has been established as a safe alternative to open surgical treatment. However, these available treatments have poor long-term patency, requiring close surveillance and multiple repeat interventions. Recently, covered stents have been proposed and their efficacy assessed for the treatment of recalcitrant central venous stenosis and obstruction. Moreover, newly proposed algorithms for the surgical management of CVD warrant consideration. Here, we seek to provide an updated review of the current literature on the various treatment modalities for CVD.

    Full Text Available Introduction: The correlation of central venous pressure (CVP with inferior vena cava (IVC sonographic diameter has been reported in several studies. However, few studies have attempted to find the best anatomic location of measurement. Therefore, the purpose of this study was determining the best anatomic location to find precise correlation between CVP and IVC diameter using transesophageal echocardiography (TEE. Methods: In the present diagnostic accuracy study, patients in need of central venous catheterization and TEE were enrolled. Maximum diameter of IVC were measured during expiratory phase of respiratory cycle at the level of diaphragm, 2cm above the diaphragm and at the point of entry into the right atrium using SonoSite TEE device. CVP was measured using an electronic transducer connected to the central venous line. The best location for sonography was determined via calculating and comparing area under the receiver operating characteristics (ROC curve (AUC. Results: 39 patients were enrolled (53.8% female. Mean CVP was 6.8 ± 1.4 mmHg and 25 (64.1% patients had normal CVP, while 14 (35.9% showed elevated CVP (> 6 mmHg. Evaluating AUC showed that IVC diameter (p = 0.01, aorta diameter (p = 0.01 and IVC / aorta ratio (p = 0.004 had acceptable correlation with CVP. Point of entry of IVC into the right atrium with AUC of 0.98 (95% CI: 0.95 – 1.00 was the location of highest correlation with CVP. Conclusion: Based on the present findings, the IVC sonographic diameter and IVC / aorta ratio had acceptable correlation with CVP at the level of IVC entry into the right atrium.

    To evaluate the risk factors associated with an increased risk of symptomatic peripherally inserted central venous catheter (PICC)-related venous thrombosis. Retrospective analyses identified 2313 patients who received PICCs from 1 January 2012 to 31 December 2013. All 11 patients with symptomatic PICC-related venous thrombosis (thrombosis group) and 148 who did not have thromboses (non-thrombosis group) were selected randomly. The medical information of 159 patients (age, body mass index (BMI), diagnosis, smoking history, nutritional risk score, platelet count, leucocyte count as well as levels of D-dimer, fibrinogen, and degradation products of fibrin) were collected. Logistic regression analysis was undertaken to determine the risk factors for thrombosis. Of 2313 patients, 11 (0.47%) were found to have symptomatic PICC-related venous thrombosis by color Doppler ultrasound. Being bedridden for a long time (odds ratio [(OR]), 17.774; P=0.0017), D-dimer >5 mg/L (36.651; 0.0025) and suffering from one comorbidity (8.39; 0.0265) or more comorbidities (13.705; 0.0083) were the major risk factors for PICC-catheter related venous thrombosis by stepwise logistic regression analysis. Among 159 patients, the prevalence of PICC-associated venous thrombosis in those with ≥1 risk factor was 10.34% (12/116), in those with ≥2 risk factors was 20.41% (10/49), and in those with >3 risk factors was 26.67% (4/15). Being bedridden >72 h, having increased levels of D-dimer (>5 mg/L) and suffering from comorbidities were independent risk factors of PICC-related venous thrombosis.

    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.

    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.)

    Full Text Available Background and Aim: The clinical applicability of substitution of central venous oxygen saturation for mixed venous oxygen saturations in monitoring global tissue hypoxia is still a matter of controversy. Hence aim of the study is comparison of paired samples of mixed venous and central venous oxygen saturation and comparison in relation to cardiac index in varying hemodynamic conditions. Materials and Methods: Prospective clinical observation: Postoperative cardiac surgical ITU: 60 adult patients,> 18 years of age of either sex: A PAC was inserted through ® IJV, triple lumen catheter was inserted through ® IJV. Blood samples were taken from distal tip of PAC and central venous catheters. An arterial blood sample was drawn from either radial or femoral arterial line. Measurements: Continuous cardiac output monitoring. Analysis of blood samples for hemoglobin concentration and oxygen saturation. Mixed venous oxygen saturations and central venous oxygen saturations were compared. The study was carried over a period of 30h in the postoperative period and samples were taken at 6h intervals. Patients were classified into three groups as follows depending on the CI: Low (< 2.5 L/m 2, medium (2.5-4 L/m 2, high (> 4 L/m2 and correlated with Svo 2 and Scvo 2 . Results: 298 Comparative sets of samples were obtained. Svo2 was consistently lower than Scvo2 throughout the study period. The difference was statistically significant. By using Bland - Altman plot, the mean difference between Svo 2 and Scvo 2 (Svo 2 -Scvo 2 was - 2.9% ± 5.14 and confidence limits are + 7.17% and - 12.97%. The co-efficient r is > 0.7 throughout the study period for all paired samples. The correlation Svo 2 and Scvo 2 with cardiac index in all the three groups were> 0.7. Conclusion: Scvo 2 and Svo 2 are closely related and are interchangeable. Even though individual values differ trends in Scvo 2 may be substituted for trend in Svo 2

    Full Text Available Insertion of central venous port (CVP catheter in the cancer population is associated with increased incidence of venous thromboembolic events (VTE. However, trials have shown limited benefit of antithrombotic treatment to prevent catheter-related venous thrombosis. This prospective observational cohort study was designed to assess the incidence of VTE closely related to CVP implantation in patients with cancer and undergoing chemotherapy, and to identify a high risk subgroup of patients. Between February 2006 and December 2011, 1097 consecutive cancer patients with first CVP implantation were included. Catheter-related VTE were defined as deep venous thrombosis in the arm, with or without pulmonary embolism (PE, or isolated PE. The incidence of CVP-associated VTE was 5.9% (IC95 4.4–7.3% at 3 months, and 11.3% (IC95 9.4–13.2% at 12 months. The incidence of any VTE was 7.6% (IC95 6.0–9.3% at 3 months, and 15.3% (IC95 13.1–17.6% at 12 months. High Khorana risk score and lung cancer were significant predictors of 3 month VTE. In conclusion, this large cohort study of patients with first CVP catheter implantation confirms the high incidence of VTE associated with the CVP implantation and allow identifying high risk patients who may benefit from thromboprophylaxis.

    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

    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.

    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.

    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.

Patients received 1% lidocaine (L, buffered 1% lidocaine (LB, or 2% chloroprocaine (CP injected around the internal jugular vein for procedural analgesia for central venous access. Patients reported pain via a standard linear visual analog scale, with 0 representing no pain and 10 being the worst pain imaginable.Results: Overall patient perception of pain was better with CP and L than LB with mean scores of CP 2.4, L 2.6, LB 4.2. Pain with injection mean scores were CP 2.1, L 2.5, LB 3.2. Pain with catheter placement scores were CP 2.5, L 1.7, LB 3.4. Operator assessment of overall pain values were CP 1.9, L 2.2, LB 3.4. LB consistently scored the worst, though compared with CP, this only reached statistical significance in overall patient pain and pain at catheter insertion compared with L.Conclusion: Though chloroprocaine scored better than lidocaine in 3 of 4 parameters, this trend did not achieve statistical significance. Adding sodium bicarbonate to lidocaine isn’t justified in routine practice, nor is routine replacement of lidocaine with chloroprocaine.Keywords: local anesthesia, analgesia, central venous access, lidocaine, chloroprocaine

    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.

    Stenting of the central veins is well established for treating localized venous stenosis. The techniques regarding catheter preservation for central venous catheters in the superior vena cava have been described. We describe here a method for stent implantation in the superior vena cava and the left brachiocephalic vein, and principally via a single jugular venous puncture, while saving a left sided jugular central venous catheter in a patient suffering from central venous stenosis of the superior vena cava and the left brachiocephalic vein.

    Full Text Available Introduction: Central venous catheters (CVC are part of daily clinical practice, regarding treatment of critically ill patients in the Intensive Care Unit (ICU. Infections associated with CVC, are a serious cause of morbidity and mortality, thus making as a demanding need the adoption of clinical protocols for the care in ICU. Aim: The aim of this review was to explore the nursing care to prevent CVC’s infections in ICU. Method and material: The methodology followed included reviews and research studies. The studies were carried out during the period 2000-2014 and were drawn from foreign electronic databases (Pubmed, Medline, Cochrane and Greek (Iatrotek, on the nursing care of CVC, in the ICU to prevent infections. Results: The literature review showed that the right choice of dressings on the point of entry, the antiseptic treatment solution, the time for replacement infusion sets, the flushing of central venous catheter, the hand disinfection and finally the training of nursing staff, are the key points to prevent CVC’s infections in ICU. Conclusions: Education and compliance of nurses regarding the instructions of CVC's care, are the gold standard in the prevention of infections.

    The arterial and mixed venous carbon dioxide tension gradient has been shown to increase when there is a decrease in cardiac output. Monitoring central venous gases is an attractive alternative to monitoring mixed venous gases in circulatory failure because central venous catheterisation is a less invasive procedure than pulmonary artery catheterisation. This study aims to evaluate the agreement between central venous-arterial carbon dioxide (CVA-CO2) and mixed venous-arterial carbon dioxide (SVA-CO2) tension gradients and assess whether CVA-CO2 tension gradient can be used to predict cardiac output in circulatory failure. Samples of arterial, central venous and mixed venous blood were obtained from 16 patients with circulatory failure at different inspired oxygen concentrations and cardiac indexes within 24 hours of study enrolment. CVA-CO2 and SVA-CO2 tension gradient were not interchangeable numerically (bias = 0.14 mmHg, 95% limits of agreement: -3.0 to 3.2 mmHg). CVA-CO2 (Spearman correlation coefficient r = -0.385) and SVA-CO, (r = -0.578) tension gradient were significantly correlated with the cardiac index but the cardiac index only accounted for 21% and 32% of the variability of CVA-CO, and SVA-CO2 tension gradient, respectively. The ability of CVA-CO2 tension gradient (area under the ROC curve = 0.77, 95% confidence interval [CI]: 0.49-0.99; P = 0.08) to predict a low cardiac output state (cardiac index tension gradient appeared to be limited to their negative predictive value to exclude a low cardiac output state when CVA-CO, or SVA-CO, tension gradient was normal (< or =5 mmHg).

Methods We performed 390 cases ( cases/times) of temporary internal jugular vein catheterization, 40 cases of central venous catheter with cuffs and 150 cases of femoral vein catheterization respectively. There were 68 cases of catheter infection occurred in the central venous catheter indwelling period. Each case of catheter infection was sent to the labora-tory for bacterial culture. Results The total infection rate of central venous catheter in hemodialysis patients was 11. 7%. The predominant pathogens of central venous catheter-related infection were Staphylococcus aureus,Escherichia coli,Acinetobacter bau-mannii complex strains and Staphylococcus epidermidis respectively. The infection rate occurred in femoral vein catheter was higher than the internal jugular vein catheterization. Conclusion Systemic antibiotics or topical application for sealing central venous cathe-ters and pull out central venous catheters is effective in the treatment of central venous catheter-related infection.

  15. Ultrasonography: A novel approach to central venous cannulation

    Full Text Available Background: Portable ultrasound machines are highly valuable in ICUs, where a patient′s condition might not permit shifting the patient to the USG department for imaging. Traditionally central lines are put blindly using anatomical landmarks, which often result in complications such as difficulty in access, misplaced lines, pneumothorax, bleeding from inadvertent arterial punctures, etc. Ultrasonography provides "real time" imaging, i.e., the needle can be visualized entering the vein. Aims: We performed a study to compare USG guided central venous cannulation (CVC and conventional anatomical landmark approach to CVC, in terms of ease of cannulation, time consumed, and associated complications. Settings and Design: The study was performed in a 16-bed open ICU. Eighty patients were randomly divided in two groups. Materials and Methods: The right internal jugular vein (IJV was cannulated in all. In Group I, a portable ultrasound machine was used during cannulation. The vessels were visualized in the transverse section with the internal carotid artery (ICA identified as a circular pulsatile structure, while the IJV as a lateral, oval nonpulsatile structure. The needle was inserted perpendicular to the skin under visualization on the US screen. Central venous line was then inserted by the Seldinger technique. In Group II, CVC was performed by the conventional landmark approach. The parameters studied included time for insertion, attempts required, and complications encountered. Statistical Analysis: The database of all parameters was analyzed using SPSS software version 10.5. Results: The mean time to successful insertion was 145 and 176.4 sec in groups I and II, respectively (p = 0.00. An average of 1.2 attempts per cannulation was required for group I, while 1.53 for group II (p = 0.03: 10% witnessed arterial puncture and 2.5% pneumothorax in group I and none in group II. Conclusion: USG-guided CVC is thus easier, quicker, and safer than

    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.

    Typical indications for central venous catheters (CVCs) are hemodialysis (HD), apheresis, total parenteral nutrition, analgesia, chemotherapy, long-term antibiotic therapy and cases of difficult or absent peripheral venous access. One of the largest medical services requesting CVC insertion is nephrology for HD patients. Demographics dictate that the demand for CVCs will continue to grow over the next few decades, placing striking demands on interventional radiology departments. In our centre, interventional radiologists now place nearly all percutaneously inserted HD CVCs. Radiologists provide rapid access to CVC services with significantly fewer complications than CVCs placed by other clinicians. With the demand for CVC management increasing and available operating room time decreasing, many clinicians now refer CVC insertions to radiologists. As well, clinicians who ordinarily place their own lines often refer high-risk patients, such as those who are obese or uncooperative and those with burns or coagulopathy. Our experience, derived from over 7000 CVC insertions, manipulations and removals, has allowed us to continually progress and improve our techniques, many of which are summarized here. (author)

    Central venous catheters (CVCs) are associated with occlusive, infectious, and thrombotic complications. The aim of this study was to determine if internal CVC tip position was correlated with subsequent complications. This was an institutional review board approved single-center retrospective review of 169 consecutive patients who underwent placement of 203 semipermanent CVCs. Using post-placement chest X-rays, a de novo scale of internal catheter tip position was developed. Major complications were recorded. A logistic regression analysis was used to determine if catheter tip position predicted subsequent complications. There were 78 men and 91 women with a mean age of 48 ± 11 years. There were 21 catheter tips placed in the subclavian/innominate veins, 32 in the upper superior vena cava, 113 in the atriocaval junction, and 37 in the right atrium. There were 83 complications occurring in 61 (36.1 %) patients, including sepsis in 40 (23.7 %), venous thrombosis in 18 (10.7 %), catheter occlusion in 16 (9.5 %), internal catheter repositioning in 6 (3.6 %), pneumothorax in 2 (1.2 %), and death in 1 (0.6 %). An internal catheter tip position peripheral to the atriocaval junction resulted in a catheter that was more likely to undergo internal repositioning (p venous thrombosis (p catheters were more likely to develop sepsis (45 %) than patients whose catheters were inserted through the upper extremity veins (18 %) (p catheter-associated morbidity and potentially mortality, the internal catheter tip should be positioned at the atriocaval junction or within the right atrium and femoral insertion sites should be avoided whenever possible.

    The Peripherally Inserted Central Catheter (PICC) has been used as a safe venous access for infants at risk. The aim of this study was to describe the knowledge and practice of nurses from the five public Neonatal Intensive Care Units, of Recife-PE, Brazil, about the use of the PICC. The sample was comprised by 52 nurses; data were collected from January to February/2010. It was found that 64,8% of nurses did not have license for insertion of the PICC. Only two units routinely used the PICC. About the indication of the access, the accuracy was above 70%. In unit B only 8,3% of nurses reported adequate initial location of the catheter tip. It was concluded that is necessary greater incentives to train nurses to use the PICC.

    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.

    Long-term utilization of central venous catheters (CVCs) for parenteral nutrition has a high incidence of central venous complications including infections, occlusions, and stenosis. We report the case of a 31-year-old woman presenting with a malabsorption caused by short gut syndrome due to congenital aganglionic megacolon. The patient developed a chronic occlusion of all central neck and femoral veins due to long-term use of multiple CVCs over more than 20 years. In patients with central venous occlusion and venous transformation, the implantation of a totally implanted port system by accessing collateral veins is an option to continue long-term parenteral nutrition when required. A 0.014-in. Whisper guidewire (Terumo, Tokyo) with high flexibility and steerability was chosen to maneuver and pass through the collateral veins. We suggest this approach to avoid unfavorable translumbar or transhepatic central venous access and to conserve the anatomically limited number of percutaneous access sites.

    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'.

    Full Text Available Central venous Catheterization (CVC is a commonly performed procedure for venous access. It is associated with several complications. We report a rare case of extra luminal entrapment of guide wire during CVC placement in right jugular vein. We report a case of 28 years old female patient presented in our emergency with history of entrapped guide wire in right side of neck during CVC. X-ray showed coiling of guide wire in neck. CT Angiography showed guide wire coursing in between common carotid artery and internal jugular vein (IJV, closely abutting the wall of both vessels. The guide wire was coiled with end coursing behind the esophageal wall. Guide wire was removed under fluoroscopic guide manipulation under local anesthesia. We want to emphasize that even though CVC placement is common and simple procedure, serious complication can occur in hands of untrained operator. The procedure should be performed under supervision, if done by trainee. Force should never be applied to advance the guide wire if resistance is encountered.

    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.

    1993-02-01

    A 5 year old girl with ASD was scheduled for open heart surgery. A central venous catheter was placed via the right infraclavicular vein after induction of anesthesia. Thirty minutes after insertion of the catheter, a decrease in arterial pressure and pulse pressure, an increase in heart rate and central venous pressure were observed. Cardiac tamponade was revealed by rapid opening of the chest. Gushing blood out of a hole in the right ventricular free wall was confirmed by pericardiotomy. The hemodynamics were stabilized by blood transfusion and surgical closure of the hole on the ventricle. This perforation was thought to be caused by careless insertion of a relatively stiff central venous catheter.

  16. Heparin Leakage in Central Venous Catheters by Hemodynamic Transport

    Science.gov (United States)

    Barbour, Michael; McGah, Patrick; Gow, Kenneth; Aliseda, Alberto

    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 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.

    Full Text Available Central venous catheterization is a common practice in the management of critically ill patients and is associated with various complications, such as Bloodstream Infections (BSI, which are major determinants of increased morbidity, mortality and healthcare expenses. Few studies have addressed factors that predict mortality in patients with this complication. The aim of this study was to investigate factors associated with mortality in patients with Central Venous Catheter (CVC-related BSI in an intensive care unit of a tertiary care hospital in the Federal District, Brazil. This was a retrospective and observational study, in which all CVC-related BSI that occurred between January 2008 and December 2010 were reviewed. We obtained demographic, clinical, biochemical and microbiological data from medical records and investigated its association with mortality during ICU stay. There were 4,504 ICU admissions during the study period and 68 were complicated by CVC-related BSI (4.09 per 1000 catheter-days, most due to gram-negative organisms (45.6%. Overall mortality was 59.7%. Death risk was significantly associated with mechanical ventilation (OR 27.8, 95% CI 3.28-250, p-1 in survivors vs. 73.9 mg dL-1 in non-survivors, p = 0.001. Mortality was not associated with other clinical or biochemical features, neither with microbiological variables, although lethality was high among patients with gram-positive infections (77% Vs 58.33% for fungi and 54.83% for gram-negative. CVC-related BSI was associated with high absolute mortality, which was predicted by mechanical ventilation and a higher number of invasive devices other than the CVC. Knowledge of local factors predictive of mortality is critical for planning strategies to reduce death risk associated with this complication.

    Full Text Available Abstract Introduction Central venous access devices are widely used in hospital practice. Complications associated with their use are well described and reviewed. In this paper, we report a former complication that in turn created a new complication during a standardized procedure. Case presentation We report the case of an 81-year-old Caucasian woman requiring total parenteral nutrition due to a high-debt enterocutaneous fistula. In a previous right subclavian catheterization a fragmentation of the tip of the catheter, probably not recognized at the time, provoked an extrinsic compression of the vessel. Conclusion Fragmentation of a central venous catheter is a possible complication of catheterization and can be missed. Control of a catheter is imperative after its removal, even if not always practiced.

    AIM: To investigate the effect of low central venous pressure (LCVP) on blood loss during hepatectomy for hepatocellular carcinoma (HCC).METHODS: By the method of sealed envelope,50 HCC patients were randomized into LCVP group (n = 25) and control group (n = 25). In LCVP group,CVP was maintained at 2-4 mmHg and systolic blood pressure (SBP) above 90 mmHg by manipulation of the patient's posture and administration of drugs during hepatectomy, while in control group hepatectomy was performed routinely without lowering CVP. The patients'preoperative conditions, volume of blood loss during hepatectomy, volume of blood transfusion, length of hospital stay, changes in hepatic and renal functions were compared between the two groups.RESULTS: There were no significant differences in patients' preoperative conditions, maximal tumor dimension, pattern of hepatectomy, duration of vascular occlusion, operationtime, weight of resected liver tissues, incidence of post-operative complications, hepatic and renal functions between the two groups. LCVP group had a markedly lower volume of total intraoperative blood loss and blood loss during hepatectomy than the control group, being 903.9±180.8 mL vs 2 329.4±2 538.4(W=495.5, P<0.01) and 672.4±429.9 mL vs1 662.6± 1932.1 (W=543.5, P<0.01). There were no remarkable differences in the pre-resection and post-resection blood losses between the two groups. The length of hospital stay was significantly shortened in LCVP group as compared with the control group, being 16.3±6.8 d vs21.5 ± 8.6 d (W= 532.5, P<0.05).CONCLUSION: LCVP is easily achievable in technique.Maintenance of CVP≤4 mmHg can help reduce blood loss during hepatectomy, shorten the length of hospital stay, and has no detrimental effects on hepatic or renal function.

    2002-04-01

    To analyse the effectiveness of percutaneous treatment of central venous obstruction in patients undergoing hemodialysis. In 100 patients, 107 central venous strictures (56 subclavian (occlusion:21, stenosis:35) and 51 innominate (occlusion:23,stenosis:28)) were assessed, and 170 percutaneous angioplasty procedures were performed. Balloon dilation of the venous lumen was the preferred mode, but if dilation was incomplete we inserted a stent at the site of the stricture. Technical success, procedural complications and the long-term patency rate were evaluated, and the patency difference according to location and degree of stricture, the existence of DM, and any history of central catheter insertion was also determined. We inserted 52 stents in 170 procedures, in 157 (92.4%) of which initial technical success was achieved. Stent migration occurred in two cases and balloon rupture in three. The 6- and 12-month primary patency rates were 46.2% and 24.1%, respectively, and the mean patency rate was 8.5 months. The 1-, 2-and 3-year accumulative patency rates were 59.8%, 47.5% and 35.7%, respectively, and the mean patency rate was 23.5 months. Other than in the history of central catheter insertion, there were no statistically significant differences in patency rates (p=0.0128). In hemodialysis patients with a central venous stricture, percutaneous angioplasty is a safe and useful procedure, but to maintain long-term central venous patency, repeated interventions are required.

    2016-01-01

    Full Text Available Central venous access is an important aspect of neonatal intensive care management. 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.

    2012-02-01

    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.

  11. Transposition of cephalic vein to rescue hemodialysis access arteriovenous fistula and treat symptomatic central venous obstruction

    Felipe Jose Skupien

    2014-03-01

    Full Text Available It is known that stenosis or central venous obstruction affects 20 to 50% of patients who undergo placement of catheters in central veins. For patients who are given hemodialysis via upper limbs, this problem causes debilitating symptoms and increases the risk of loss of hemodialysis access. We report an atypical case of treatment of a dialysis patient with multiple comorbidities, severe swelling and pain in the right upper limb (RUL, few alternative sites for hemodialysis vascular access, a functioning brachiobasilic fistula in the RUL and severe venous hypertension in the same limb, secondary to central vein occlusion of the internal jugular vein and right brachiocephalic trunk. The alternative surgical treatment chosen was to transpose the RUL cephalic vein, forming a venous necklace at the anterior cervical region, bypassing the site of venous occlusion. In order to achieve this, we dissected the cephalic vein in the right arm to its junction with the axillary vein, devalved the cephalic vein and anastomosed it to the contralateral external jugular vein, providing venous drainage to the RUL, alleviating symptoms of venous hypertension and preserving function of the brachiobasilic fistula.

    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.

    central venous thrombosis. Logistic regressive analysis revealed that high level of homocysteic acid was the important risk factor for central venous thrombosis in HD patients with indwelling catheterization of the internal jugular vein.Conclusions The prevalence of central venous thrombosis in Chinese HD patients with indwelling catheterization of the internal jugular vein is quite high, especially in those patients with diabetes mellitus, malignant tumor, high levels of serum lipoprotein and homocysteic acid. Its clinical symptoms are insidious but dangerous. High level of homocysteic acid may be the important risk factor for central venous thrombosis in Chinese HD patients with indwelling catheterization of the internal jugular vein.

    Ten intensive care patients and five healthy volunteers each received a bolus injection of lidocaine HCl (100 mg, 2%) over an injection period of 5 s. After 0.5, 1, 2, 4, 8, 15 and 25 min arterial, central venous and peripheral venous blood samples were collected. In four of the volunteers, arterial and central venous samples were also taken about 10 s after the end of injection. The fluorescence polarization method by means of the Abbott-TDx system was used, and plasma concentrations of lidocaine were determined. The measurements showed that lidocaine levels in central venous plasma 10 s after the end of administration were higher than those in arterial plasma. By 30 s after administration the opposite situation had developed, so that arterial concentrations were higher than those in central venous plasma. This relation did not change throughout the study, though the two levels became closer, as is shown by the ratios (Table 3, Fig. 2). Concentrations in peripheral venous plasma increased more slowly but remained far below those in arterial and central venous plasma, at least for the first 8 min. After 15 min lidocaine levels were almost the same in all three samples. During the entire study there were no ECG changes, and neither heart rate nor blood pressure showed any significant deviation from the values obtained at the beginning. The volunteers had minor toxic manifestations, such as dizziness, tinnitus and a metallic taste in the mouth; one person had a sensation of pressure in his chest, which improved following oxygen administration.(ABSTRACT TRUNCATED AT 250 WORDS)

    Intravenous prostacyclins are a valuable treatment for patients with severe pulmonary arterial hypertension, leading to improved exercise capacity, haemodynamics, quality of life and survival. Unfortunately, due to the short half-life of these drugs, they need to be administered continuously through central venous catheters. Despite aseptic technique, regular dressing changes, tunneled central venous catheters and patient education, patients are exposed to central venous catheter associated infections. These infections cause significant morbidity and mortality. The clinical presentation, microbiology, consequences and management of these central venous catheter associated infections in pulmonary arterial hypertension patients treated with intravenous prostacyclins are discussed.

    With advancing paediatric healthcare, the use of central venous lines has become a fundamental part of management of neonates and children. Uses include haemodynamic monitoring and the delivery of lifesaving treatments such as intravenous fluids, blood products, antibiotics, chemotherapy, haemodialysis and total parenteral nutrition (TPN). Despite preventative measures, central venous catheter-related infections are common, with rates of 0.5-2.8/1000 catheter days in children and 0.6-2.5/1000 catheter days in neonates. Central line infections in children are associated with increased mortality, increased length of hospital and intensive care unit stay, treatment interruptions, and increased complications. Prevention is paramount, using a variety of measures including tunnelling of long-term devices, chlorhexidine antisepsis, maximum sterile barriers, aseptic non-touch technique, minimal line accessing, and evidence-based care bundles. Diagnosis of central line infections in children is challenging. Available samples are often limited to a single central line blood culture, as clinicians are reluctant to perform painful venepuncture on children with a central, pain-free, access device. With the advancing evidence basis for antibiotic lock therapy for treatment, paediatricians are pushing the boundaries of line retention if safe to do so, due to among other reasons, often limited venous access sites. This review evaluates the available paediatric studies on management of central venous line infections and refers to consensus guidelines such as those of the Infectious Diseases Society of America (IDSA).

    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.

Nós relatamos dois casos de tamponamento cardíaco, diagnosticados por ecocardiograma transtorácico, seguido de pericardiocentese de urgência e drenagem pericárdica cirúrgica como complicação de cateterização venosa umbilical. Em um caso, a ponta do cateter estava adequadamente localizada e, no outro caso, não. Em ambos os casos, solução hiperosmolar estava sendo infundida. Apesar de situação incomum, esta deve ser sempre considerada em neonato, evoluindo com choque cardiogênico sem causa aparente.Cardiac tamponade secondary to the use of central venous catheter is a rare complication; however, it is potentially reversible when it is caught in time. We report two cases of cardiac tamponade that was diagnosed using a transthoracic echocardiography, followed by urgent pericardiocentesis and surgical pericardial drainage as a complication from umbilical venous catheterization. In one case, the tip of the catheter was properly placed, and in the other case, it was not. In both cases, a hyperosmolar solution was being injected. Although it may be an uncommon situation, it should be always considered as a possibility in a newborn who develops cardiogenic shock without an apparent cause.

    Maintenance of central venous access in patients with chronic medical conditions such as short bowel syndrome demands forethought and ingenuity. We describe an innovative technique for re-utilizing central venous access sites in patients who have chronic central venous access needs. Records of patients undergoing this technique were reviewed between August 2012 and December 2015. The technique involves "cutting-down" to the sterile fibrous tunnel that naturally forms around tunneled catheters. The fibrous sheath is then isolated and controlled much as would be done for a venous "cut-down." A separate exit site is then created for the new catheter and it is tunneled to the "cut-down" site per routine. The non-functioning catheter is then removed from the surgical field. The proximal fibrous sheath is finally cannulated either directly with the new catheter or with a wire/dilator system. This technique effectively re-uses the same venous access point while allowing for a complete change of the physical line and external site. Twenty attempts at this technique were made in twelve patients; six patients underwent the site re-utilization procedure multiple times. Re-using the fibrous tunnel to re-cycle the internal catheter site was successful in seventeen of twenty attempts. All patients had chronic conditions leading to difficult long-term central venous access [short bowel syndrome (6), hemophilia (2), cystic fibrosis (1), chronic need for central IV access (3)]. Indications for catheter replacement included catheter occlusion/mechanical failure/breakage (9), dislodgement (6), infection (1), and inadequate catheter length due to patient growth (4). Broviac/Hickman catheter sites were most commonly re-used (13; one failure); re-using a portcath site was successful in 5 of 7 attempts. There were no short term infections or mechanical complications. We describe a novel technique for salvaging tunneled central venous catheter access sites. This technique is well suited

    The implantation of permanent (>14 days) central venous catheters is constantly increasing, accelerated by a trend toward outpatient therapies. Subcutaneous tunneled and non-tunneled catheters as well as port systems are available. The interventional radiologist plays an important role in the implantation of central venous catheters as well as in detection and treatment of any complications. Various access ways via peripheral and central veins are described and the implantation techniques for the different systems explained. The use of peel-away sheaths allows the radiologist to implant subcutaneous tunneled catheters via the Seldinger technique without surgical preparation. Procedure-related early and late complications may occur, and the radiologist plays an important role in the surveillance and management of catheter-associated complications. This review demonstrates the different catheter systems and implantation techniques. (orig.)

    When planning parenteral nutrition (PN), the proper choice, insertion, and nursing of the venous access are of paramount importance. In hospitalized patients, PN can be delivered through short-term, non-tunneled central venous catheters, through peripherally inserted central catheters (PICC), or - for limited period of time and with limitation in the osmolarity and composition of the solution - through peripheral venous access devices (short cannulas and midline catheters). Home PN usually requires PICCs or - if planned for an extended or unlimited time - long-term venous access devices (tunneled catheters and totally implantable ports). The most appropriate site for central venous access will take into account many factors, including the patient's conditions and the relative risk of infective and non-infective complications associated with each site. Ultrasound-guided venepuncture is strongly recommended for access to all central veins. For parenteral nutrition, the ideal position of the catheter tip is between the lower third of the superior cava vein and the upper third of the right atrium; this should preferably be checked during the procedure. Catheter-related bloodstream infection is an important and still too common complication of parenteral nutrition. The risk of infection can be reduced by adopting cost-effective, evidence-based interventions such as proper education and specific training of the staff, an adequate hand washing policy, proper choices of the type of device and the site of insertion, use of maximal barrier protection during insertion, use of chlorhexidine as antiseptic prior to insertion and for disinfecting the exit site thereafter, appropriate policies for the dressing of the exit site, routine changes of administration sets, and removal of central lines as soon as they are no longer necessary. Most non-infective complications of central venous access devices can also be prevented by appropriate, standardized protocols for line insertion

    Full Text Available Introduction. Lactate is an important indicator of tissue perfusion. The objective of this study is to evaluate if there are significant differences between the arterial and central venous measurement of lactate in pediatric patients with sepsis and/or septic shock. Methods. Longitudinal retrospective observational study. Forty-two patients were included between the age of 1 month and 17 years, with a diagnosis of sepsis and septic shock, who were admitted to the intensive care unit of a university referral hospital. The lactate value obtained from an arterial blood sample and a central venous blood sample drawn simultaneously, and within 24 hours of admission to the unit, was recorded. Results. The median age was 2.3 years (RIC 0,3–15, with a predominance of males (71.4%, having a 2.5 : 1 ratio to females. Most of the patients had septic shock (78.5% of pulmonary origin (50.0%, followed by those of gastrointestinal origin (26.1%. Using Spearman’s Rho, a 0.872 (p<0.001 correlation was found between arterial and venous lactate, which did not vary when adjusted for age (p<0.05 and the use of vasoactive drugs (p<0.05. Conclusion. There is a good correlation between arterial and venous lactate in pediatric patients with sepsis and septic shock, which is not affected by demographic variables or type of vasoactive support.

  19. Non-invasive bedside assessment of central venous pressure: scanning into the future.

    Directory of Open Access Journals (Sweden)

    Jacques Rizkallah

    Full Text Available Noninvasive evaluation of central venous pressure (CVP can be achieved by assessing the Jugular Venous Pressure (JVP, Peripheral Venous Collapse (PVC, and ultrasound visualization of the inferior vena cava. The relative accuracy of these techniques compared to one another and their application by trainees of varying experience remains uncertain. We compare the application and utility of the JVP, PVC, and handheld Mini Echo amongst trainees of varying experience including a medical student, internal medicine resident, and cardiology fellow. We also introduce and validate a new physical exam technique to assess central venous pressures, the Anthem sign.Patients presenting for their regularly scheduled echocardiograms at the hospital echo department had clinical evaluations of their CVP using these non-invasive bedside techniques. The examiners were blinded to the echo results, each other's assessments, and patient history; their CVP estimates were compared to the gold standard level 3 echo-cardiographer's estimates at the completion of the study.325 patients combined were examined (mean age 65, s.d. 16 years. When compared to the gold standard of central venous pressure by a level 3 echocardiographer, the JVP was the most sensitive at 86%, improving with clinical experience (p<0.01. The classic PVC technique and Anthem sign had better specificity compared to the JVP. Mini Echo estimates were comparable to physical exam assessments.JVP evaluation is the most sensitive physical examination technique in CVP assessments. The PVC techniques along with the newly described Anthem sign may be of value for the early learner who still has not mastered the art of JVP assessment and in obese patients in whom JVP evaluation is problematic. Mini Echo estimates of CVPs are comparable to physical examination by trained clinicians and require less instruction. The use of Mini Echo in medical training should be further evaluated and encouraged.

    Full Text Available Central venous cannulation is often associated with complications during insertion even by expert′s hand and with the aid of ultrasound. We encountered a patient for central line insertion through the right internal jugular vein having a retropharyngeal abscess of tubercular origin. We accidentally punctured the abscess cavity leading to increased respiratory distress and subsequent need of intubation to the patient. This kind of complication during central line insertion has never been reported before. We intend to report such a case to alert everyone about the grave complications it can lead to and the methods to minimize them in the times ahead.

    To evaluate the results and complications of placement of implantable port according to approach routes and methods. Between April 2001 and October 2002, a total of 103 implantable chemoport was placed in 95 patients for chemotherapy using preconnected type (n=39) and attachable type (n=64). Puncture sites were left subclavian vein (n=35), right subclavian vein (n=5), left internal jugular vein (n=9), right internal jugular vein (n=54). We evaluated duration of catheterization days, complications according to approach routes and methods. Implantable chemoport was placed successfully in all cases. Duration of catheterization ranged from 8 to 554 days(mean 159, total 17,872 catheter days). Procedure related complications occurred transient pulmonary air embolism (n=1), small hematoma (n=1) and malposition in using preconnected type (n=2). Late complications occurred catheter migration (n=5), catheter malfunction (n=3), occlusion (n=1) and infection (n=11). Among them 15 chemoport was removed (14.5%). Catheter migration was occured via subclavian vein in all cases (13%, p=.008). Infection developed in 10.7% of patients(0.61 per 1000 catheter days). There were no catheter-related central vein thrombosis. Implantation of chemoport is a safe procedure. Choice of right internal jugular vein than subclavian vain vein for puncture site has less complications. And selection of attachable type of chemoport is convenient than preconnected type. Adequate care of chemoport is essential for long patency.

    Misplacement of percutaneously inserted central venous catheters (PCVCs) into the paraspinal venous plexus can result in devastating outcomes. Several cases have been reported in the literature together with an explanation of the mechanism. To describe three premature babies with their PCVCs inserted through the left saphenous vein that ended up in the lumbar spinal dural venous plexus. Plain radiographs obtained to check positions showed an unusual 360 curl of the PCVC in the left inguinal area. We believe that misplacement of the catheter into the paraspinal venous plexus could be diagnosed with great accuracy if such a curl is seen. (orig.)

    β-catenin regulates the transcription of genes involved in diverse biological processes, including embryogenesis, tissue homeostasis and regeneration. Endothelial cell (EC)-specific gene-targeting analyses in mice have revealed that β-catenin is required for vascular development. However, the precise function of β-catenin-mediated gene regulation in vascular development is not well understood, since β-catenin regulates not only gene expression but also the formation of cell-cell junctions. To address this question, we have developed a novel transgenic zebrafish line that allows the visualization of β-catenin transcriptional activity specifically in ECs and discovered that β-catenin-dependent transcription is central to the bone morphogenetic protein (Bmp)-mediated formation of venous vessels. During caudal vein (CV) formation, Bmp induces the expression of aggf1, a putative causative gene for Klippel-Trenaunay syndrome, which is characterized by venous malformation and hypertrophy of bones and soft tissues. Subsequently, Aggf1 potentiates β-catenin transcriptional activity by acting as a transcriptional co-factor, suggesting that Bmp evokes β-catenin-mediated gene expression through Aggf1 expression. Bmp-mediated activation of β-catenin induces the expression of Nr2f2 (also known as Coup-TFII), a member of the nuclear receptor superfamily, to promote the differentiation of venous ECs, thereby contributing to CV formation. Furthermore, β-catenin stimulated by Bmp promotes the survival of venous ECs, but not that of arterial ECs. Collectively, these results indicate that Bmp-induced activation of β-catenin through Aggf1 regulates CV development by promoting the Nr2f2-dependent differentiation of venous ECs and their survival. This study demonstrates, for the first time, a crucial role of β-catenin-mediated gene expression in the development of venous vessels.

    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.

All the patients underwent right heart and pulmonary artery (PA catheterization at the diagnosis and over time during treatment.Results and discussion. All the patients included in the trial met the pre-capillary pulmonary hypertension (PH criteria: mean pulmonary artery pressure (MPAP ≥25 mm Hg; and PA wedge pressure (PAWP <15 mm Hg. The exclusion of other causes of PH (pulmonary fibrosis, left heart disease, and thromboembolism, as well as a high transpulmonary pressure gradient >15 mm Hg and pulmonary vascular resistance (PVR >3 Wood units could diagnose PAH in all our patients. There was a statistically highly significant association between pathological hemodynamic changes and functional class (FC. FC was found to be most closely correlated with right atrial pressure (RAP, cardiac output (CO, PVR, and cardiac index (CI. Among the most common manifestations of heart failure, only the presence of peripheral edemas was associated with worse hemodynamic parameters in PAH. It should be noted that out of two biomarkers (N-terminal pro-brain natriuretic peptide and uric acid, the former is largely related to the magnitude of changes in hemodynamic factors. The critical values of hemodynamic parameters were due to extreme edema – anasarca (RAP >17 mm Hg

    The technical success and complications were especially focused on and evaluated the need for fixation of a port under fluoroscopic guidance placement of the totally implantable central venous access ports for long term central venous access. Two hundred eighty nine consecutive patients (170 men, 119 women, mean age: 52-year-old) who underwent venous port implantation for the administration of chemotherapy were followed over a 1-month period. The procedures were performed in the angiographic suite by an interventional radiologist and all access was through the right jugular vein, except for the patients who had undergone a right mastectomy. The procedures were performed in the following order: 1) venous puncture, 2) making a pocket, 3) catheter tunneling, 4) port insertion, 5) catheter sizing, and 6) insertion. A port which was connected to the tunneled catheter was inserted into the minimally sized subcutaneous pocket with the aid of a small retractor. A follow-up was performed with medical records and chest radiographs. The follow-up period for evaluating the venous port ranged from 59 to 329 days (mean: 175 days) The procedures performed to gain right jugular vein access were successful without difficulty in all cases. The 18 patients that underwent procedures to gain left jugular vein access encountered some difficulty upon insertion of a catheter into the SVC due to encountering the tortuous left brachiocephalic vein. No complications occurred during and immediately after the procedure. In one case the port chamber rotated within the subcutaneous pocket; however, no catheter migration or malfunction occurred. If port insertion was followed by catheter insertion, the port chamber can be tightly implanted in the minimally sized pocket. This would avoid the need for fixation of the catheter to the port chamber leading into the pocket

    Introducción: los catéteres venosos centrales (CVC) son de gran utilidad en la práctica médica actual; sin embargo, no están exentos de riesgos, lo que incrementa la morbilidad y mortalidad, especialmente en los recién nacidos (RN). El objetivo fue registrar la frecuencia de complicaciones de los CVC y su duración en RN en una unidad de cuidados intensivos neonatales (UCIN) de tercer nivel. Métodos: se realizó un estudio observacional descriptivo, prolectivo en la UCIN del Hospital de Pediatría del Centro Médico Nacional Siglo XXI. Se registraron variables demográficas, perinatales y del CVC. Resultados: se incluyeron 123 RN a quienes se les colocaron 152 CVC. La técnica más usada para la inserción del CVC fue la punción (percutánea o subclavia) en 56.6 % (n = 86). En 48.7 % (n = 74) de los CVC se presentó alguna complicación. Las más frecuentes fueron colonización en 32.4 % (n = 24) y bacteriemia relacionada con CVC en 27 % (n = 20). La probabilidad de duración de los CVC libres de complicaciones fue de 93.4 % a los 10 días y de 91.4 % a los 17 días. Los catéteres venosos no centrales tuvieron menor probabilidad de duración. Conclusión: la mayoría de las complicaciones de los CVC se presentaron en las primeras dos semanas de haber sido instalados. Las complicaciones infecciosas fueron las más frecuentes.

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

    The aim of this study was to predict the optimal depth for insertion of a left-sided central venous catheter in children. Using 3D chest computed tomography angiography, we measured the distance from a point where the internal jugular vein is at the superior border of the clavicle, and from a point where the subclavian vein is inferior to the anterior border of the clavicle, to the junction of the superior vena cava and the right atrium in 257 children. Linear regression analysis revealed that the distances correlated with age, weight and height. Simple formulae for the depth of a central venous catheter via the left internal jugular vein (0.07 × height (cm)) and the left subclavian vein (0.08 × height (cm)) were developed to predict placement of the central venous catheter tip at the junction of the superior vena cava with the right atrium. Using these fomulae, the proportion of catheter tips predicted to be correctly located was 98.5% (95% CI 96.8-100%) and 94.0% (95% CI 90.8-97.3%), respectively.

    Background: Venous thrombosis is a common occurrence in cancer patients, developing spontaneously or in combination with indwelling central venous devices (CVD). Purpose: To analyze the multidetector CT (MDCT) prevalence, appearance, and significance of catheter related thoracic venous thrombosis in oncologic patients and to determine the percentage of thrombi identified in the original reports. Material and Methods: Five hundred consecutive patients were considered. Inclusion criteria were: presence of a CVD; availability of a contrast-enhanced MDCT; and cancer history. Exclusion criteria were: direct tumor compression/infiltration of the veins; poor image quality; device tip not in the scanned volume; and missing clinical data. Seventeen (3.5%) out of the final 481 patients had a diagnosis of venous thrombosis. Results: Factors showing the highest correlation with thrombosis included peripherally-inserted CVD, right brachiocephalic vein tip location, patient performance status 3, metastatic stage disease, ongoing chemotherapy, and longstanding CVD. The highest prevalence was in patients with lymphoma, lung carcinoma, melanoma, and gynecologic malignancies. Eleven out of 17 cases had not been identified in the original report. Conclusion: CVD-related thrombosis is not uncommon in cancer patients and can also be observed in outpatients with a good performance status and a non-metastatic disease. Thrombi can be very tiny. Radiologists should be aware of the possibility to identify (or overlook) small thrombi

    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.

    Full Text Available ABSTRACTBackground: Identifying risk factors related to Central Venous Line (CVL placement could potentially minimize Central Line-Associated Venous Thrombosis (CLAVT. We sought to identify the clinical factors associated with CLAVT in children. Methods: Over a 3-year period, 3,733 CVLs were placed at a tertiary-care children’s hospital. Data were extracted from the electronic medical records of patients with clinical signs and symptoms of venous thromboembolism (VTE, diagnosed using Doppler ultrasonography and/or echocardiography. Statistical analyses examined differences in CLAVT occurrence between groups based on patient and CVL characteristics (type, brand, placement site, and hospital unit. Results: Femoral CVL placement was associated with greater risk for developing CLAVT (OR 11.1, 95% CI 3.9-31.6, p<0.0001. CVLs placed in the NICU were also associated with increased CLAVT occurrence (OR 5.3, 95% CI 2.1-13.2, p=0.0003. CVL brand was also significantly associated with risk of CLAVT events. Conclusion: Retrospective analyses identified femoral CVL placement and catheter type as independent risk factors for CLAVT, suggesting increased risks due to mechanical reasons. Placement of CVLs in the NICU also led to an increased risk of CLAVT, suggesting that small infants are at increased risk of thrombotic events. Alternative strategies for CVL placement, thromboprophylaxis, and earlier diagnosis may be important for reducing CLAVT events.

    Full Text Available Establishment of long-term central venous access is a sine qua non step for bone marrow transplantation in children. Most frequently, long-term central venous access has been obtained via blind percutaneous cannulation of subclavian and internal jugular veins or via internal jugular vein cutdown. In order to avoid some potential minor and major complications associated with the subclavian or internal jugular approaches, the authors describe an easy, simple and safe method for central venous access through an external jugular vein cutdown that should be of interest to readers involved in the field of bone marrow transplantation. It should be also considered for children as well as adults needing central venous access via an external catheter - or totally implantable port - for reasons other than bone marrow transplantation, such as total parenteral nutrition and administration of chemotherapeutic agents.O estabelecimento de um acesso venoso central de longa duração é uma condição sine qua non para realizar o transplante de medula óssea em crianças. Com frequência, este acesso tem sido obtido através da punção percutânea das veias subclávia e jugular interna ou via dissecção da jugular interna. Com o objetivo de evitar algumas complicações maiores e menores associadas com a subclávia e a jugular interna, os autores descrevem um método simples, fácil e seguro para o acesso venoso central através de dissecção da veia jugular externa. Este método deveria ser de interesse dos leitores envolvidos com o transplante de medula óssea e ser considerado também para crianças e/ou adultos que necessitem de cateter venoso central de longa permanência (externo ou totalmente implantável devido a outras razões, como a nutrição parenteral ou a administração de agentes quimioterápicos.

    Malfunctioning tunneled hemodialysis central venous catheters (CVCs), because of thrombotic or infectious complications, are frequently exchanged. During the CVC exchanging procedure, there are several possible technical complications, as in first insertion, including air embolism. Prevention remains the key to the management of air embolism. Herein, we emphasize the technical tricks capable of reducing the risk of air embolism in long-term CVC exchange. In particular, adoption of a 5 to 10 degrees Trendelenburg position, direct puncture of the previous CVC venous lumen for guide-wire insertion, as opposed to guide-wire introduction after cutting the CVC, a light manual compression of the internal jugular vein venotomy site after catheter removal. The Valsalva maneuvre in collaborating patients, valved introducers, and correction of hypovolemia are also useful precautions. Principles of air embolism diagnosis and treatment are also outlined in the article.

    Full Text Available Most hematological patients suffer a significant venous damage related to different administrated intravenous therapy, being necessary to place central venous catheters (CVC. CVC is associated with various complications. The most common catheter-related complications are occlusion and infection. To avoid such of them, the development of protocols for insertion and care are needed, as well as recording and following up complications. To this end, we propose a cross-sectional carried out during 13 months whose main goal is to know the incidence of CVC- related complications (mainly occlusion and infection in hematological patients.Population included all the =14 ages patients admitted to different hematological units at Ramon y Cajal and Gregorio Marañón hospitals in Madrid and who signed informed consent. Socio-demographic, clinical characteristics and complications were entered into a log which included a pursuit of care protocol.

    Treatment of chronic diseases in children is a special medical problem. Maintaining constant access to the central vascular system is necessary for long-term hemato-oncological and nephrological therapies as well as parenteral nutrition. Providing such access enables chemotherapic treatment, complete parenteral nutrition, long-term antibiotic therapy, hemodialysis, treatment of intensive care unit patients, monitoring blood pressure in the pulmonary artery and stimulation of heart rate in emergency situations as well as treatment of patients suffering from complications, especially when chances of access into peripheral veins are exhausted. Continuous access to the central vascular system is desirable in the treatment of chronically ill children. Insertion of a central venous catheter line eliminates the unnecessary pain and stress to a child patient accompanying injection into peripheral vessels. In order to gain long-term and secure access to the central venous system, respecting the guidelines of the Center for Disease Control and Prevention contained in the updated 'Guidelines for the Prevention of Intravascular Catheter-Related Infections' is necessary.

    Pil Young Jung

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

    We describe a case of a patient with a functional kidney transplant who was admitted to our department with clinically evident central vein stenosis (CVS) 7 years after the removal of a central venous catheter (CVC) from the right internal jugular vein. The catheter was used as a hemodialysis access for a 2-month period. In the interval before his last admission, the patient suffered two episodes of deep vein thrombosis. Investigation revealed heterozygosity for factor V Leiden, the most common inherited thrombophilia encountered in 5% of Caucasians, and anticoagulation treatment was started. Magnetic resonance angiography showed stenosis just after the convergence of the right subclavian vein with the internal jugular vein to the innominate vein. Transluminal angioplasty restored venous patency and right upper arm edema resolved. Coexistence of CVS, accompanied by hemodynamic changes and endothelial dysfunction, with thrombophilia fulfill all the elements of the Virchow's triad. Therefore, the patient was at great risk for central vein thrombosis, from which he was possibly protected by the early administration of anticoagulant treatment. This case indicates that CVS can be asymptomatic for several years after CVC removal and also raises the question if thrombophilia workup and investigation for CVS may be beneficial in every patient with CVC placement in order to avoid any harmful outcomes.

    To compare prevalence and patterns of intravertebral collateral enhancement in patients with and without central venous obstruction (CVO). Chest CTs performed between 1/1/2000 and 12/15/2012 with reports containing terms indicating CVO were identified. All contrast enhanced CTs were examined for the presence of CVO and collateral venous pathways. If intravertebral collateral enhancement was present, the pattern was recorded as nodular, linear, or both. In 209 suspected cases of CVO, 53 (25 %) were confirmed with obstruction and 156 (75 %) were without obstruction. In patients with CVO, 47 % (25/53) demonstrated collateral venous flow through an intravertebral marrow pathway compared to 5 % (8/156) of patients without CVO (P < 0.0001). The most common level of enhancement was the upper thoracic spine, involving only the vertebral body. Nodular, linear, and combined nodular-linear enhancement patterns were seen with similar frequency. Nodular intravertebral collateral enhancement was mistaken for sclerotic metastases in 33 % (3/9) of cases. Intravertebral collateral enhancement was seen in almost half the patients with CVO and when nodular enhancement is present, it is important to differentiate between metastatic lesions and enhancement related to CVO.

    AIM: To establish the relationship between the tip position of tunnelled central venous catheters (CVC) and the incidence of venous thrombosis. MATERIALS AND METHODS: A randomly sampled, retrospective review of 428 CVC inserted into 334 patients was performed. The chest radiograph obtained post-catheter insertion, as well as follow-up radiographs, linograms, venograms and Doppler ultrasounds (US), were reviewed. RESULTS: The median follow-up was 72 days (range 1-720 days), with a total follow-up of 23,040 line days. Venous thrombosis occurred in five out of 191 (2.6%) CVC in a distal position (distal third of the superior vena cava (SVC) or right atrium (RA)), five of 95 (5.3%) in an intermediate position (middle third of the SVC) and 20 of 48 (41.7%) in a proximal position (proximal third SVC or thoracic inlet veins). There was a significant difference in thrombosis rate between lines sited with the tip in a distal compared with a proximal position (p<0.0005). CVC with tips in a proximal position were 16 times more likely to thrombose than those in a distal position. None of the 58 CVC with the tip located in the RA thrombosed or caused complications. CONCLUSION: Distal placement of tunnelled CVC, either in the distal third of the SVC or proximal RA is optimal.

    Semiquantitative (Maki and quantitative (Brun- Buisson culture techniques were employed in the diagnosis of catheter-related bloodstream infections (CRBSI in patients who have a short-term central venous catheter (inserted for 30 days. The diagnosis of CRBSI was based on the results of semiquantitative and quantitative culture of material from the removed catheters. Catheter tips (118 from 100 patients were evaluated by both methods. Semiquantitative analysis revealed 34 catheters (28.8% colonized by ≥15 colonyforming units (cfu, while quantitative cultures (34 catheters, 28.8% showed the growth of ≥103 cfu/mL. Bacteremia was confirmed in four patients by isolating microorganisms of identical species from both catheters and blood samples. Using the semiquantitative culture technique on short-term central venous catheter tips, we have shown that with a cut-off level of ≥15 cfu, the technique had 100.0% sensitivity, specificity of 68.4%, 25.0% positive predictive value (PPV and 100.0% negative predictive value (NPV, efficiency of 71.4% and a prevalence of 9.5%. The quantitative method, with a cut-off limit of ≥103 cfu/mL, gave identical values: the sensitivity was 100.0%, specificity 68.4%, positive predictive value (PPV 25.0%, negative predictive value (NPV 100.0%, efficiency 71.4% and prevalence 9.5%. We concluded that the semiquantitative and quantitative culture methods, evaluated in parallel, for the first time in Brazil, have similar sensitivity and specificity.

    Full Text Available Abstract Critically ill surgical patients are always at increased risk of actual or potentially life-threatening health complications. Central/peripheral venous lines form a key part of their care. We review the current evidence on incidence of central and peripheral venous catheter-related bloodstream infections in critically ill surgical patients, and outline pathways for prevention and intervention. An extensive systematic electronic search was carried out on the relevant databases. Articles were considered suitable for inclusion if they investigated catheter colonisation and catheter-related bloodstream infection. Two independent reviewers engaged in selecting the appropriate articles in line with our protocol retrieved 8 articles published from 1999 to 2011. Outcomes on CVC colonisation and infections were investigated in six studies; four of which were prospective cohort studies, one prospective longitudinal study and one retrospective cohort study. Outcomes relating only to PICCs were reported in one prospective randomised trial. We identified only one study that compared CVC- and PICC-related complications in surgical intensive care units. Although our search protocol may not have yielded an exhaustive list we have identified a key deficiency in the literature, namely a paucity of studies investigating the incidence of CVC- and PICC-related bloodstream infection in exclusively critically ill surgical populations. In summary, the diverse definitions for the diagnosis of central and peripheral venous catheter-related bloodstream infections along with the vastly different sample size and extremely small PICC population size has, predictably, yielded inconsistent findings. Our current understanding is still limited; the studies we have identified do point us towards some tentative understanding that the CVC/PICC performance remains inconclusive.

    Full Text Available Background and Aims: Central venous catheter placement is an important procedure for ICU (Intensive Care Unit patients. We studied the usefulness of ultrasonography for placement of central venous catheter by in-experienced anesthetists. Materials and Methods: A prospective observational study of 32 patients requiring central venous access (CVA in surgical ICU (SICU. Data collected were patient′s demographics, indication, type of catheter, success rate, attempts, complication rate and access time were recorded and compared with other studies. Result: The overall success rate was 89.5% in the IJV (Internal Jugular Vein and 92.3% for SCV (Subclavian Vein group. The success rates for insertion at first, second, and third attempt were 52.6%, 31.6%, and 5.2% for IJV and 46.2% and 53.8% for SCV. Average number of attempts made for IJV cannulation was 1.74 +/- 1.04 and 1.54 +/- 0.51 for SCV. The total time taken for IJV access was 858.78 +/- 381.9 sec, whereas in the SCV group, it was 984 +/- 328.98 seconds. In our study, overall rate of complication was 21.05% (4/19 patients for IJV and 23.07% (3/13 patients for SCV insertion. Incidence of various complications like arterial puncture, misplacement of CVC, hematoma, pneumothorax, and hemothorax were also noted. Conclusion: This study concludes that real time ultrasound guidance during IJV and SCV cannulation can achieve higher success rate, fewer complications, number of attempts, and failure rate among inexperienced anesthetists.

    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.

    Purpose: To retrospectively compare immediate and long-term outcome of central venous infusion port inserted via right high versus low jugular vein approaches. Materials and methods: The study included 163 patients (125 women patients, 38 men patients; age range, 18-79 years; mean age, 53 years); 142 patients underwent port insertion with low jugular vein approach and 21 patients with high jugular vein approach. The causes of high jugular vein puncture were metastatic lymphadenopathy (n = 7), operation scar (n = 6), radiation scar (n = 5), failure of low jugular vein puncture (n = 2), and abnormal course of right subclavian artery (n = 1). Medical records and radiologic studies were reviewed retrospectively to determine and compare the outcome and the occurrence of complication related to port. Results: The procedure-related complications were all minor (n = 14, 8.6%) in both groups; hematoma (n = 4, 2.8% in low jugular puncture group and n = 1, 4.8% in high jugular puncture group, p = 0.6295), air embolism (n = 2, 1.4% in low jugular puncture group and n = 0 in high jugular puncture group, p = 0.5842) and minor bleeding (n = 5, 3.5% in low jugular vein puncture group and n = 2, 9.5% in high jugular vein puncture group, p = 0.2054). The average length of follow-up was 431 days for low jugular vein puncture group and 284 days for high jugular vein puncture group. The difference between two groups was significant (p = 0.0349). The reasons for catheter removal were patients' death (59 in low jugular puncture group and 14 in high jugular puncture group, p = 0.0465), suspected infection (11 in low jugular vein puncture group and 2 in high jugular vein puncture group, p = 0.8242), catheter occlusion (four in low jugular vein puncture group and one in high jugular vein puncture group, p = 0.6583). The catheter tip migrated upward an average of 1.86 cm (range, -0.5 to 5.0 cm) in low jugular vein puncture group and 1.56 cm (range, 0-3.6 cm) in high jugular vein

    Acute kidney injury (AKI) in cardiac surgery has traditionally been linked to reduced arterial perfusion. There is ongoing evidence that central venous pressure (CVP) has a pivotal role in precipitating acute renal dysfunction in cardiac medical and surgical settings. We can regard this AKI driven by systemic venous hypertension as 'kidney congestive failure'. In the cardiac surgery population as a whole, when the CVP value reaches the threshold of 14 mmHg in postoperative period, the risk of AKI increases 2-fold with an odds ratio (OR) of 1.99, 95% confidence interval (95% CI) of 1.16-3.40. In cardiac surgery subsets where venous hypertension is a hallmark feature, the incidence of AKI is higher (tricuspid disease 30%, carcinoid valve disease 22%). Even in the non-chronically congested coronary artery bypass population, CVP measured 6 h postoperatively showed significant association to renal failure: risk-adjusted OR for AKI was 5.5 (95% CI 1.93-15.5; P = 0.001) with every 5 mmHg rise in CVP for patients with CVP <9 mmHg; for CVP increments of 5 mmHg above the threshold of 9 mmHg, the risk-adjusted OR for AKI was 1.3 (95% CI 1.01-1.65; P = 0.045). This and other clinical evidence are discussed along with the underlying pathophysiological mechanisms, involving the supremacy of volume receptors in regulating the autonomic output in hypervolaemia, and the regional effect of venous congestion on the nephron. The effect of CVP on renal function was found to be modulated by ventricular function class, aetiology and acuity of venous congestion. Evidence suggests that acute increases of CVP should be actively treated to avoid a deterioration of the renal function, particularly in patients with poor ventricular fraction. Besides, the practice of treating right heart failure with fluid loading should be avoided in favour of other ways to optimize haemodynamics in this setting, because of the detrimental effects on the kidney function.

    Full Text Available Introduction. Pericardial effusion (PCE and tamponade can cause significant morbidity and mortality in neonates. Such cases have been reported in the literature in various contexts. Case Presentation. A 6-day old neonate with meconium aspiration syndrome and persistent pulmonary hypertension of newborn on high frequency oscillator ventilation and inhaled nitric oxide was referred to our hospital with a large pericardial effusion causing hemodynamic compromise. Prompt pericardiocentesis led to significant improvement in the cardio-respiratory status and removal of the central line prevented the fluid from reaccumulating. Cellular and biochemical analysis aided in the diagnosis of catheter related etiology with possibility of infusate diffusion into the pericardial space. Conclusion. We present this paper to emphasize the importance of recognizing this uncommon but serious complication of central venous catheters in intensive care units. We also discuss the proposed hypothesis for the mechanism of production of PCE.

    The use of peripherally inserted central catheter (PICC) line for central venous access in thermally injured patients has increased in recent years despite a lack of evidence regarding safety in this patient population. A recent survey of invasive catheter practices among 44 burn centers in the United States found that 37% of burn units use PICC lines as part of their treatment protocol. The goal of this study was to compare PICC-associated complication rates with the existing literature in both the critical care and burn settings. The methodology involved is a single institution retrospective cohort review of patients who received a PICC line during admission to a regional burn unit between 2008 and 2013. Fifty-three patients were identified with a total of seventy-three PICC lines. The primary outcome measurement for this study was indication for PICC line discontinuation. The most common reason for PICC line discontinuation was that the line was no longer indicated (45.2%). Four cases of symptomatic upper extremity deep vein thrombosis (5.5%) and three cases of central line-associated bloodstream infection (4.3%, 2.72 infections per 1000 line days) were identified. PICC lines were in situ an average of 15 days (range 1 to 49 days). We suggest that PICC line-associated complication rates are similar to those published in the critical care literature. Though these rates are higher than those published in the burn literature, they are similar to central venous catheter-associated complication rates. While PICC lines can be a useful resource in the treatment of the thermally injured patient, they are associated with significant and potentially fatal risks.

    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.

Eyes were categorized into group A (n = 22, eyes with ODH, group B (n = 22, fellow eyes without ODH, and group C (n = 29, NTG eyes without an episode of ODH. A contact lens ophthalmodynamometer was used to measure CRVP and central retinal arterial pressure (CRAP.Intraocular pressure (IOP measured on the day of contact lens ophthalmodynamometry showed no difference among groups. However, the mean baseline IOP in group A was significantly lower than that in group C (P = .008. The CRVP in group A (29.1 ± 10.8 mmHg was significantly lower than that in group C (40.1 ± 8.8 mmHg, P = .001, but similar to that in group B (30.5 ± 8.7 mmHg, P = .409. A similar relationship was noted for CRAP. No significant eye-associated variable for ODH was found in group A and B by conditional logistic regression analysis (all P > 0.05. However, multivariate logistic regression analysis in groups A and C revealed that low mean baseline IOP (odds ratio [OR] = 0.69, 95% confidence interval [CI] 0.49-0.98, P = 0.043 and low CRVP (OR = 0.88, 95% CI 0.80-0.95, P = 0.003 were associated with ODH.CRVP was lower in NTG eyes with ODH than in eyes without an episode of ODH, but similar to that of fellow eyes without ODH. These imply less likelihood of association between increased central retinal venous resistance and ODH.

    Objective: To evaluate the efficacy of stent placement for treating upper extremity central venous obstruction in chronic hemodialysis patients. Methods and Material: Between January 1999 and October 2001, we inserted metallic stents into the upper extremity central veins of 14 patients with shunt dysfunction and/or arm swelling. The indications for stent placement were stenosis or occlusion of the central vein in the upper extremity used for dialysis. Six of the individuals were diagnosed with subclavian vein stenosis, and 5 with brachiocephalic vein stenosis. Of the remaining 3 patients, 2 had subclavian vein occlusion, and 1 had left brachiocephalic vein occlusion. Results: All the stent placement procedures were technically successful, and there were no major complications. Follow-up ranged from 2 weeks to 29 months. The 1-, 3-, 6- and 12-month primary stent patency rates were 92.8, 85.7, 50 and 14.3%, respectively. Repeat interventions, including percutaneous transluminal angioplasty and additional stent placement, were required in 9 patients. The 3-, 6-, 12-month, and 2-year assisted primary stent patency rates were 100, 88.8, 55.5 and 33.3%, respectively. Conclusion: Endovascular stent placement is an effective alternative to surgery in patients with shunt dysfunction due to obstruction of an upper extremity central vein. Repeated interventions are usually required to prolong stent patency.

    Excess blood pressure remains the most important risk factor for cardiovascular and renal disease. Poly pharmacy has been proved safe and effective under clinical trial circumstances; however, the majority of patients fail to sustain pharmaceutical persistence and adherence. The opportunity to offer patients a treatment or device in addition or perhaps instead of drug therapy alone may significantly broaden the options for patients and allow greater success in hypertensive therapy. In this review, we examine the potential of a fixed-volume central arterial-venous anastomosis to reduce blood pressure in hypertensive patients, review possible mechanisms by which the anastomosis may reduce blood pressure, and consider the unique clinical trial opportunities posed by this therapy.

    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.

    Kocuria kristinae is a catalase-positive, coagulase-negative, Gram-positive coccus found in the environment and in normal skin and mucosa in humans; however, it is rarely isolated from clinical specimens and is considered a nonpathogenic bacterium. We describe a case of catheter-related bacteremia due to K. kristinae in a young adult with propionic acidemia undergoing periodic hemodialysis. The patient had a central venous catheter implanted for total parenteral nutrition approximately 6 months prior to the onset of symptoms because of repeated acute pancreatitis. K. kristinae was isolated from two sets of blood cultures collected from the catheter. Vancomycin followed by cefazolin for 16 days and 5-day ethanol lock therapy successfully eradicated the K. kristinae bacteremia. Although human infections with this organism appear to be rare and are sometimes considered to result from contamination, physicians should not underestimate its significance when it is isolated in clinical specimens.

    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.

The aim of this study was to compare the effect of catheter locking with taurolidine vs heparin in biofilm formation in central venous catheters. Forty-eight children with cancer were randomized to catheter locking by heparin (n...... = 22) or taurolidine (n = 26), respectively. After removal, catheters were examined by standardized scanning electron microscopy to assess quantitative biofilm formation. Biofilm was present if morphologically typical structures and bacterial cells were identified. Quantitative and semi......-quantitative cultures were also performed. Biofilm was identified in 23 of 26 catheters from the taurolidine group and 21 of 22 catheters from the heparin group. A positive culture was made of six of the catheters locked with taurolidine and heparin, respectively (p = 0.78). The rate of catheter-related bloodstream...

    Neonatal infectious pathology remains one of the main causes of morbidity and mortality in this age group. The introduction of plasticized catheters for the administration of medication, fluidotherapy and parenteral nutrition was a significant advance in treatment of patients at risk, but also led to the appearance of infectious complications. Negative coagulase staphylococcus is the principal pathogen in most neonatal intensive care units. Recent studies have examined the prophylactic use of vancomycin in preterm babies receiving parenteral nutrition. We have evaluated the efficacy of this procedure, applied via the central venous catheters employed for all neonates, within the intensive care unit over a period of one year. Prophylactic vancomycin administered via the catheters significantly reduced the incidence of Gram-positive infections, despite the presence within this group of a greater number of septic risk factors than in the control group.

    Central venous catheters (CVCs) account for the largest proportion of thrombotic events in pediatric patients. Questions remain regarding adequate treatment and prevention methods. We surveyed pediatric hematology/oncology specialists, using hypothetical cases to assess management strategies for acute CVC thrombosis and secondary prevention. Survey respondents varied in the use of the thrombophilia evaluation (33.3%, 41/123) and duration of treatment (6 weeks: 54.1%, 66/122). Secondary CVC prophylaxis was utilized by 36.6% (45/123) of respondents and by 24.4% (30/123) but only if there was a documented thrombophilia. This heterogeneity highlights the need for clinical studies to address these important clinical questions.

We report an interesting case of a 68-year-old lady with a central venous thrombosis coincident with both a dialysis catheter infection and a recent pacemaker insertion. Two-dimensional transesophageal echocardiography was unable to delineate whether the thrombosis was involved with the pacemaker wire or due to the tunneled catheter infection. The use of 3D echocardiography was able to produce distinct images aiding diagnosis. This circumvented the need for invasive investigations and inappropriate, high-risk removal of the pacing wire. This case highlights the emerging application of 3D echocardiography in routine nephrology practice.

    Full Text Available Introduction: To survey emergency physicians (EP regarding the frequency of use of ultrasound guidance for placement of central venous catheters (UGCVC and to assess their perceptions regarding the technique and barriers to its implementation.Methods: A 25-question Web-based survey was e-mailed to all members of the Colorado chapter of the American College of Emergency Physicians with a listed e-mail address. A total of 3 reminderswere sent to nonresponders.Results: Responses were received from 116 out of 330 invitations. Ninety-seven percent (n¼112 of respondents indicated they have an ultrasound machine available in their emergency department, and 78% indicated they use UGCVC. Seventy-seven percent (n ¼ 90 agreed with the statement, ‘‘Ultrasound guidance is the preferred method for central venous catheter placement in the emergencydepartment.’��� However, 23% of respondents stated they have received no specific training in UGCVC. Twenty-six percent (n ¼28 of respondents stated they felt ‘‘uncomfortable’’ or ‘‘very uncomfortable’’with UGCVC, and 47% cite lack of training in UGCVC as a barrier to performing the technique.Conclusion: Although the majority of surveyed EPs feel UGCVC is a valuable technique and do perform it, a significant percentage reported receiving no training in the procedure and also reported being uncomfortable performing it. Nearly half of those surveyed cited lack of training as a barrier to more widespread implementation of UGCVC. This suggests that there continues to be a need for education and training of EPs in UGCVC.

    Full Text Available Abstract Background To optimize the fluid status of adult patients with severe malaria, World Health Organization (WHO guidelines recommend the insertion of a central venous catheter (CVC and a target central venous pressure (CVP of 0-5 cmH2O. However there are few data from clinical trials to support this recommendation. Methods Twenty-eight adult Indian and Bangladeshi patients admitted to the intensive care unit with severe falciparum malaria were enrolled in the study. All patients had a CVC inserted and had regular CVP measurements recorded. The CVP measurements were compared with markers of disease severity, clinical endpoints and volumetric measures derived from transpulmonary thermodilution. Results There was no correlation between the admission CVP and patient outcome (p = 0.67 or disease severity (p = 0.33. There was no correlation between the baseline CVP and the concomitant extravascular lung water (p = 0.62, global end diastolic volume (p = 0.88 or cardiac index (p = 0.44. There was no correlation between the baseline CVP and the likelihood of a patient being fluid responsive (p = 0.37. On the occasions when the CVP was in the WHO target range patients were usually hypovolaemic and often had pulmonary oedema by volumetric measures. Seven of 28 patients suffered a complication of the CVC insertion, although none were fatal. Conclusion The WHO recommendation for the routine insertion of a CVC, and the maintenance of a CVP of 0-5 cmH2O in adults with severe malaria, should be reconsidered.

    Full Text Available Abstract Background A non-invasive surrogate measurement for central venous oxygen saturation (ScVO2 would be useful in the ED for assessing therapeutic interventions in critically ill patients. We hypothesized that either linear or nonlinear mathematical manipulation of the partial pressure of oxygen in breath at end expiration (EtO2 would accurately predict ScVO2. Methods Prospective observational study of a convenience sample of hemodialysis patients age > 17 years with existing upper extremity central venous catheters were enrolled. Using a portable respiratory device, we collected both tidal breathing and end expiratory oxygen and carbon dioxide concentrations, volume and flow on each patient. Simultaneous ScVO2 measurements were obtained via blood samples collected from the hemodialysis catheter. Two models were used to predict ScVO2: 1 Best-fit multivariate linear regression equation incorporating all respiratory variables; 2 MathCAD to model the decay curve of EtO2 versus expiratory volume using the least squares method to estimate the pO2 that would occur at Results From 21 patients, the correlation between EtO2 and measured ScVO2 yielded R2 = 0.11. The best fit multivariate equation included EtCO2 and EtO2 and when solved for ScVO2, the equation yielded a mean absolute difference from the measured ScVO2 of 8 ± 6% (range -18 to +17%. The predicted ScVO2 value was within 10% of the actual value for 57% of the patients. Modeling of the EtO2 curve did not accurately predict ScVO2 at any lung volume. Conclusion We found no significant correlation between EtO2 and ScVO2. A linear equation incorporating EtCO2 and EtO2 had at best modest predictive accuracy for ScVO2.

    2012-01-01

    Introduction: The determination of the values of central venous pressure has long been used as a guideline for volumetric therapy in the resuscitation of the critical patient, but the performance of such parameter is currently being questioned as an effective measurement of cardiac preload. This has aroused great interest in the search for more accurate parameters to determine cardiac preload and a patient's blood volume. Goals and Methods: Based on literature currently available, we aim to discuss the performance of central venous pressure as an effective parameter to determine cardiac preload. Results and Conclusion: Estimating variables such as end-diastolic ventricular area and global end-diastolic volume have a better performance than central venous pressure in determining cardiac preload. Despite the best performance of these devices, central venous pressure is still considered in our setting as the most practical and most commonly available way to assess the patient's preload. Only dynamic variables such as pulse pressure change are superior in determining an individual's blood volume. PMID:24893061

    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.

    2016-03-01

    The 3SITES study randomly assigned a nontunneled central venous catheter site in over 3000 adults treated in intensive care units. The subclavian site was associated with a lower rate of short-term complications, including catheter-related bloodstream infection and deep venous thrombosis, compared to the femoral or internal jugular site. Nephrologists should be aware of this study and should continue to advocate for alternatives to subclavian vein catheter placement in patients with chronic kidney disease who are expected to require arteriovenous access for dialysis in the future.

    PurposeEntrapment of central venous catheters (CVC) at the superior vena cava (SVC) cardiopulmonary bypass cannulation site by closing purse-string sutures is a rare complication of cardiac surgery. Historically, resternotomy has been required for suture release. An endovascular catheter release approach was developed.Materials and MethodsFour cases of CVC tethering against the SVC wall and associated resistance to removal, suggestive of entrapment, were encountered. In each case, catheter removal was achieved using a reverse catheter fluoroscopically guided over the suture fixation point between catheter and SVC wall, followed by the placement of a guidewire through the catheter. The guidewire was snared and externalized to create a through-and-through access with the apex of the loop around the suture. A snare placed from the femoral venous access provided concurrent downward traction on the distal CVC during suture release maneuvers.ResultsIn the initial attempt, gentle traction freed the CVC, which fractured and was removed in two sections. In the subsequent three cases, traction alone did not release the CVC. Therefore, a cutting balloon was introduced over the guidewire and inflated. Gentle back-and-forth motion of the cutting balloon atherotomes successfully incised the suture in all three attempts. No significant postprocedural complications were encountered. During all cases, a cardiovascular surgeon was present in the interventional suite and prepared for emergent resternotomy, if necessary.ConclusionAn endovascular algorithm to the “entrapped CVC” is proposed, which likely reduces risks posed by resternotomy to cardiac surgery patients in the post-operative period.

    Abstract Objective: to evaluate the effectiveness and safety in the use of second-generation central venous catheters impregnated in clorhexidine and silver sulfadiazine when compared with other catheters, being them impregnated or not, in order to prevent the bloodstream infection prevention. Method: systematic review with meta-analysis. Databases searched: MEDLINE, EMBASE, CINAHL, LILACS/SciELO, Cochrane CENTRAL; search in Congress Proceedings and records from Clinical Trials. Results: 1.235 studies were identified, 97 were pre-selected and 4 were included. In catheter-related bloodstream infection, there was no statistical significance between second-generation impregnated catheter compared with the non-impregnated ones, absolute relative risk 1,5% confidence interval 95% (3%-1%), relative risk 0,68 (confidence interval 95%, 0,40-1,15) and number needed to treat 66. In the sensitivity analysis, there was less bloodstream infection in impregnated catheters (relative risk 0,50, confidence interval 95%, 0,26-0,96). Lower colonization, absolute relative risk 9,6% (confidence interval 95%, 10% to 4%), relative risk 0,51 (confidence interval 95% from 0,38-0,85) and number needed to treat 5. Conclusion: the use of second-generation catheters was effective in reducing the catheter colonization and infection when a sensitivity analysis is performed. Future clinical trials are suggested to evaluate sepsis rates, mortality and adverse effects. PMID:27508901

    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.

    Central line associated bloodstream infections (CLABSIs) are a serious cause of morbidity and mortality induced by the use of central venous catheters (CVCs). Nobel metal alloy (NMA) coating is an advanced surface modification that prevents microbial adhesion and growth on catheters and thereby reduces the risk of infection. In vitro microbiological analyses have shown up to 90% reduction in microbial adhesion on coated CVC compared to uncoated ones. This study aimed to assess the blood compatibility of NMA-coated CVC according to ISO 10993-4. Hemolysis, thrombin-antithrombin (TAT) complex, platelet counts, fibrin deposition, and C3a and SC5b-9 complement activation were analyzed in human blood exposed to the NMA-coated and control CVCs using a Chandler-loop model. NMA-coated CVC did not induce hemolysis and fell in the "nonhemolytic" category according to ASTM F756-00. Significantly lower amounts of TAT were generated and less fibrin was deposited on NMA-coated CVC than on uncoated ones. Slightly higher platelet counts and lower complement markers were observed for NMA-coated CVC compared to uncoated ones. These data suggest that the NMA-coated CVC has better ex vivo blood compatibility compared to uncoated CVC. © 2015 The Authors Journal of Biomedical Materials Research Part B: Applied Biomaterials Published by Wiley Periodicals, Inc.

    To understand the vulnerability of patients with cancer to central line-associated bloodstream infections related to tunneled central venous catheters (CVCs), patients were asked to describe their line care at home and in clinic and to characterize their knowledge and experience managing CVCs. Forty-five adult patients with cancer were recruited to participate. Patients were interviewed about the type of line, duration of use, and observations of variations in line care. They also were asked about differences between line care at home and in the clinic, precautions taken when bathing, and their education regarding line care. Demographic information and primary cancer diagnosis were taken from the patients' medical records. Patients with hematologic and gastrointestinal malignancies were heavily represented. The majority had tunneled catheters with subcutaneous implanted ports. Participants identified variations in practice among nurses who cared for them. Although many participants expressed confidence in their knowledge of line care, some were uncertain about what to do if the dressing became loose or wet, or how to recognize an infection. Patients seemed to be astute observers of their own care and offered insights into practice variation. Their observations show that CVC care practices should be standardized, and educational interventions should be created to address patients' knowledge deficits.

  8. Serious Gaming to Improve the Safety of Central Venous Catheter Placement

    2013-06-01

    Full Text Available Approximately 5 million central venous catheters (CVCs are placed by physicians annually in the United States, with a complication rate of 15%.1 Guidelines and recommendations are continually being established and updated regarding CVC placement.2 While much has been done regarding training the technical skills of CVC placement using part-task trainers (i.e., mannequins, successfully finding and cannulating a central vein is but one part of the process. In fact, many steps designed to prevent untoward complications involve non-technical skills which are perhaps more important in training practitioners to safely place CVCs. First in aviation and now in healthcare, practitioners are being trained in realistic and highly interactive simulated environments so they can learn not just technical skills , but the key management and non-technical steps which make their task safer.3 One modality being used to improve performance is video gaming simulation, or "serious gaming." Gaming as a learning tool is being increasingly utilized in health care fields and can lead to better skill-based outcomes.4 As such, we have developed a game based around the placement of CVCs that will be used as a new teaching modality in a pilot program for instructing residents in safe CVC placement.

Methods 248 patients treated in ICU who needed intravascular catheterization were randomly divided into the control group (120 cases, treated with ordinary central venous catheter) and the antiseptic group (128 cases, treated with antiseptic impregnated central venous catheter). The incidence of CRI and pathogenic distribution were observed. Results The incidence of CRI in the antiseptic group was significantly lower than that of the control group (6.3% vs 14.2%, P<0.05). The pathogens of CRI were Staphytococcus aureus, Acmetabactor baumarwiii, E. Cloacae, entemcoccus, Klebsiella pneumonias and Candida albicans. Pathogenic distribution between the two groups showed no statistically significant difference (PX).O5). Conclusion Antiseptic impregnated central venous catheter can obviously reduce the incidence of CRI in patients in ICU.

    Full Text Available Koushik TripathyDepartment of Vitreoretina and Uvea, ICARE Eye Hospital & Postgraduate Institute, Noida, Uttar Pradesh, IndiaThe author read with interest the article by Browning et al.1 The author humbly wants to discuss a few facts.1. The article1 discusses grading of retinal ischemia based on optical coherence tomography features in central retinal venous occlusion. As coexisting central retinal arterial occlusion or cilioretinal arterial occlusion may also cause inner retinal hyper-reflectivity, exclusion of such cases is an important consideration before implicating central retinal venous occlusion for the ischemia. Extensive intraretinal hemorrhages are other important hindrances to the evaluation of the perfusion status of the retina using both fluorescein angiogram and optical coherence tomography.2. It would be interesting to know the gonioscopic findings, especially neovascularization of the anterior chamber angle if it was performed at presentation and during the follow-ups.3. The manuscript documented that the incidence of anterior segment neovascularization at 1 year was 8.9% in severe ischemia group.1 The incidence of anterior segment neovascularization in perfused groups was higher (15.4% and 17.6% for mild and moderate ischemia, respectively.

    Central venous catheter (CVC) placement is associated with increased risk of thrombosis in the paediatric population, particularly in relation to the type of catheter and the manner of its insertion. Here, we investigate risk factors associated with CVC-related thrombosis in children, with particular emphasis on positioning of the catheter tip. Patients aged 0-18 who underwent at least one CVC placement from 2008 to 2013 at a single centre with a subsequent follow-up echocardiogram were included for a total of 104 patients and 147 lines. Data on clinical and catheter-related risk factors were collected from patient charts. Statistical analysis using Pearson's χ tests, independent samples t-test, and odds ratios were used to assess potential risk factors for thrombosis. Neither insertion site (subclavian vein or otherwise), left- vs. right-sided insertion, nor catheter type were significant risk factors for thrombosis. There were no thrombotic events reported at the superior vena cava (SVC)-right atrium junction and no significant differences in thrombotic risk with initial tip placement in the SVC-right atrium junction vs. the SVC, right atrium, or inferior vena cava. Acute lymphoblastic leukaemia was a major clinical risk factor for thrombosis. Tip movement was common and may have been an important factor in the development of CVC-related thrombi. Prospective studies can yield insight into the role of follow-up imaging in the prevention of catheter-related thrombosis in children.

    Catheter-related thrombosis (CRT) is a serious complication in hematological patients, but the risk factors for its occurrence are not well established. The study objectives were to estimate the incidence of CRT and to identify the risk factors for developing CRT in hematological patients. In a prospective setting, 104 consecutive patients with 200 insertions of central venous catheters were enrolled into the study. The patients were screened for CRT by compression Doppler ultrasound every 10-14 days. Additionally, ultrasonography was performed in the case of clinical symptoms suggesting CRT. Over the course of 6,098 catheter days of follow-up, the incidence of CRT was 13.5 %. In 18/27 cases (66.6 %), radiological evidence of CRT was preceded by clinical symptoms. However, in 9/27 (33.3 %), CRT was clinically asymptomatic. The median times to symptomatic and asymptomatic CRT were 17 (range 1-49) and 8 (range 1-16) catheter days, respectively. In univariate analysis, the risk factors for CRT were exit-site infection (ESI) (P risk of CRT. The results of our study provide information regarding the characteristic features of the patients who are at high risk of thrombosis, for whom Doppler ultrasound screening should be considered.

    Full Text Available Hematopoietic stem cells are usually transfused through a central venous catheter (CVC, which also facilitates administration of medications and intravenous fluids. We had observed high rate of catheter-related blood-stream infection (CR-BSI at our Bone Marrow Transplantation (BMT unit despite prescribing fluoroquinolones for anti-bacterial prophylaxis. Accordingly, we implemented prophylactic use of a relatively inexpensive broad spectrum antibiotic, namely doxycycline to address this problem. We wanted to investigate whether doxycycline prophylaxis reduces CR-BSI rate. Data was collected retrospectively on 54 consecutive patients, 26 of whom received doxycycline (doxycycline group, and we compared their outcomes to a previous cohort of 28 patients who did not receive doxycycline (comparison group. The groups were comparable in regards to age, gender, hematopoietic cell transplant type, and primary diagnosis. No CVC infection (0% was observed in the doxycycline group, while 5 infection episodes (18.5% occurred in 4 patients in the comparison group (p<0.001. Episodes of CR-BSI were due to: Escherichia-coli (EC=1, coagulase-negative Staphylococcus-spp (CNSS=2, both EC & CNSS=1. Our results demonstrate that CR-BSI was reduced significantly after introducing doxycycline. This finding suggests a beneficial role for systemic use of doxycycline prophylaxis to prevent CR-BSI in adult BMT patients. Nevertheless, a randomized controlled study is warranted to confirm these findings.

    Central venous access devices (CVADs) play an essential role in the care of critically ill children. Significant challenges exist for teams in managing CVADs particularly in a community setting. The authors aimed to assess the experience of general practitioners (GPs) caring for children with CVADs. From 200 CVADs inserted in a pediatric hospital in 2009, 50 patients were randomly selected and 44 GPs were forwarded a questionnaire. Twenty (46%) GPs responded. The main reasons (n = 22) for using CVADs were medication administration (n = 11), nutrition (n = 6), and blood sampling (n = 5). Thirteen (65%) GPs had no education in CVAD management and 14 (70%) were unaware of existing guidelines. Those identified by GPs as having primary responsibility for care of CVADs in the community included hospital\\/pediatric teams (n = 9), parents (n = 3), GPs (n = 2), public health nurses (n = 1), and palliative care ("home care") teams (n = 1). The main challenges (n = 15) identified by GPs were lack of education (n = 4), line management difficulties (n = 3), infection risk (n = 3), infrequent exposure to CVADs (n = 3), and poor communication (n = 1). GPs felt that these challenges could be addressed through: education (n = 8), increased manpower and community support (n = 1), and improved communication (n = 1). This study highlights the inconsistency and challenges for GPs surrounding CVAD use in children. Further education and support is necessary to assist GPs in their use particularly when providing end-of-life care for children in the community.

    Central venous catheters (CVCs) are important for the treatment of patients with cancer, especially in the perioperative and palliative care settings. These devices not only allow for the administration of chemotherapy, parenteral nutrition, and other intravenous therapies, but they may also improve the patients' quality of life by reducing the need for repeated peripheral venipunctures. Thrombotic and infectious complications are common, especially in the long-term use of CVCs. There are different types of thrombotic complications associated with CVCs, that is, a thrombotic occlusion of the catheter, a mural thrombus at the catheter tip and classical deep vein thrombosis, which occurs most frequently in the upper extremity where the majority of long-term catheters are inserted. Infections are common complications associated with CVCs. Patients with cancer who receive intensive chemotherapy and those patients who undergo hematopoietic stem cell transplantation have a markedly increased risk for insertion site and bloodstream infections. In this review, the epidemiology and risk factors that predispose patients to CVC-related thrombosis and infection are discussed. The diagnostic and therapeutic options according to the published data and the current guidelines are summarized and data for establishing primary and secondary preventative strategies are provided.

    Full Text Available Background: The current study was designed to compare the complications and adverse effects of central venous catheter (CVC insertion under ultrasound guidance in patients with and without coagulopathy. Materials and Methods: In this clinical trial, 59 patients who needed CVC for various reasons were enrolled. Patients were divided into two groups of those with and without coagulopathy based on complete blood count, prothrombin time, partial thromboplastin time, and international normalized ratio test results, and then, CVC was inserted with ultrasound guidance in both groups. The CVC inserting site was examined for hematoma and hemorrhage in four stages at different times. Results: There was no significant difference in the terms of demographic features, catheter lumen size (P = 0.43, and number of attempting for CVC placement (odds ratio [OR] =2.35, 95% confidence interval [CI] = 0.36–15.3, P = 0.39 between two groups. Seven out of 59 patients suffered from complications (11.9% that the complications in coagulopathic patients were oozing (5.7% and superficial hematoma (8.6% while in noncoagulopathic patients were 4.2% for both complications (OR = 0.54, 95% CI = 0.09–3.07, P = 0.767. Conclusion: According to our results, it can be concluded that inserting CVC with ultrasound guidance under emergency conditions causes no serious and life-threatening complications in coagulopathic patients.

    Catheter rupture during CT angiography has prompted policies prohibiting the use of electronic injectors with peripherally inserted central venous catheters (PICCs) not only for CT but also for MRI. Consequently, many institutions mandate hand injection for MR angiography, limiting precision of infusion rates and durations of delivery. To determine whether electronic injection of gadolinium-based contrast media through a range of small-caliber, single-lumen PICCs would be safe without risk of catheter rupture over the range of clinical protocols and determine whether programmed flow rates and volumes were realized when using PICCs for contrast delivery. Experiments were performed and recorded using the Medrad Spectris Solaris EP MR Injection System. PICC sizes, contrast media and flow rates were based on common institutional protocols. No catheters were damaged during any experiments. Mean difference between programmed and delivered volume was 0.07 {+-} 0.10 mL for all experiments. Reduced flow rates and prolonged injection durations were observed when the injector's pressure-limiting algorithm was triggered, only in protocols outside the clinical range. PICCs commonly used in children can withstand in vitro power injection of gadolinium-based contrast media at protocols significantly above clinical levels. (orig.)

    The paper presents a study of the identifiability of a lumped model of the cardiovascular system. The significance of this work from the existing literature is in the potential advantage of using both arterial and central venous (CVP) pressures, two signals that are frequently monitored in the critical care unit. The analysis is done on the system's state-space representation via control theory and system identification techniques. Non-parametric state-space identification is preferred over other identification techniques as it optimally assesses the order of a model, which best describes the input-output data, without any prior knowledge about the system. In particular, a recent system identification algorithm, namely Observer Kalman Filter Identification with Deterministic Projection, is used to identify a simplified version of an existing cardiopulmonary model. The outcome of the study highlights the following two facts. In the deterministic (noiseless) case, the theoretical indicators report that the model is fully identifiable, whereas the stochastic case reveals the difficulty in determining the complete system's dynamics. This suggests that even with the use of CVP as an additional pressure signal, the identification of a more detailed (high order) model of the circulatory system remains a challenging task.

    Pediatric central venous catheter (CVC) placement is useful but associated with complications such as cardiac tamponade. We aimed to identify risk factors for death in cardiac tamponade. Published articles on pediatric CVC-associated cardiac tamponade were obtained by searching PubMed and Google and retrospectively reviewed to analyze risk factors for death. Factors examined for their effect on mortality risk included patient age, weight, CVC size, days from CVC insertion to tamponade occurrence, substances administered, insertion site, treatment, CVC material, and initial CVC tip position. Of 110 patients reported in 62 articles, 69 survived and 41 died. Among survivors, 55 of 69 patients were treated; among deaths, only 7 of 38 (OR 537.9, 95% CI 29.3-9,877, p tamponade survival. Past studies have mainly discussed how to avoid pediatric cardiac tamponade; by contrast, the present study focused on how to avoid deaths. The findings of this review suggest that cardiac tamponade survival is better when tamponade is detected early and treated promptly and might be affected by initial CVC tip position.

    Central venous cannulation is widely used in neonatal critical care. Pericardial tamponade caused by vessel wall perforation can occur if the catheter tip induces extravasation at the level of the pericardium. To investigate the level of the superior pericardial reflection in stillborn babies. We dissected 20 bodies (11 female, mean gestational age 33 6/7 weeks, range 25-43 weeks), with careful opening of the thoracic area. After injecting contrast medium into the pericardial sac, we introduced a catheter through the right internal jugular vein. We then took radiographs to analyse the relationship between visual osseous landmarks and the pericardium. Mean distance between the pericardial reflection at its upper end and the first thoracic vertebra was 1.3 cm (standard deviation [SD]: 0.3 cm) and did not extend over the 3rd intercostal space. The mean distance from the entry of the superior vena cava into the pericardial sac and the 1st thoracic vertebra was 2.3 cm (SD: 0.5). The upper end of the pericardial reflection in neonates at autopsy lies below the middle of the 3rd thoracic vertebra. The tip of an upper inserted catheter should not extend below the level of the 3rd intercostal space. (orig.)

    Full Text Available Background: We aimed to create a new and less invasive experimental corrosive oesophageal burn model using a catheter without a gastric puncture (gastrotomy. Materials and Methods: We conducted the study with two groups composed of 8 male rats. The experimental oesophageal burn was established by the application of 10% sodium hydroxide to the distal oesophagus under a pressure of 20 cmH 2 O, via 5-F double-lumen central venous catheter without a gastrotomy. The control group was given 0.9% sodium chloride. All rats were killed 24 h after administration of NaOH or 0.9% NaCl. Histologic damage to oesophageal tissue was scored by a single pathologist blind to groups. Results: The rats in the control group were observed to have no pathological changes. Corrosive oesophagitis (tissue congestion, oedema, inflammation, ulcer and necrosis was observed in rats exposed to NaOH. Conclusion: We believe that an experimental corrosive oesophageal burn can safely be created under same hydrostatic pressure without a gastric puncture using this model.

    Full Text Available Background and Aim: Central venous catheter (CVC insertion induces pain and discomfort to a conscious patient despite application of a local anaesthetic (LA field block and this pain can be greatly lessened by using additional analgesics. The aim of this study was to evaluate the efficacy of dexmedetomidine along with LA field infiltration in controlling pain and discomfort associated with CVC insertion. Methods: A prospective, randomised, double-blind, placebo-controlled trial of 54 patients scheduled for planned CVC insertion was undertaken. Patients were randomly assigned into two groups of 27 each, to receive either dexmedetomidine (1 μg/kg or 0.9% normal saline, along with LA field infiltration. Pain and discomfort score was measured at 5 time points. Results: The median pain score was worst for placebo group at local anaesthetic injection (6 [4-7] and at the end of procedure (5 [4-5], which was significantly attenuated in the dexmedetomidine group (4 [4-5] and 4 [3-5]; P = 0.007 and 0.040 respectively. The lower procedure related discomfort score in the immediate post-procedural period was statistically significant in dexmedetomidine group compared to placebo (4 [4-5] vs. 5 [4-6]; P = 0.008. Conclusions: Pre-procedural bolus dexmedetomidine infusion provides adequate analgesia and patient comfort for CVC insertion along LA field block. However, the tendency for excessive sedation and bradycardia associated with dexmedetomidine render it less desirable for this purpose.

  7. Large Right Atrial Thrombus Associated with Central Venous Catheter Requiring Open Heart Surgery

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Central venous catheters (CVC are used commonly in clinical practice. Incidences of CVC-related right atrial thrombosis (CRAT are variable, but, when right atrial thrombus is present, it carries a mortality risk of 18% in hemodialysis patients and greater than 40% risk in nonhemodialysis patients. Different pathogenic mechanisms have been postulated for the development of CRAT, which includes mechanical irritation of the myocardial wall, propagation of intraluminal clot, hypercoagulability, and hemodynamics of right atria. Presentation of CRAT may be asymptomatic or may be associated with one of the complications of CRAT like pulmonary embolism, systemic embolism, infected thrombi, or hemodynamic compromise. There are no established treatment guidelines for CRAT. We describe an interesting case of a 59-year-old asymptomatic male successfully treated with open heart surgery after failure of medical treatment for a large CRAT discovered during a preoperative evaluation for a kidney transplant. Our case underscores that early detection of CRAT may carry a favorable prognosis as opposed to waiting until catastrophic complications arise. It also underscores the importance of transesophageal echocardiography in the detection of thrombus and perhaps guides clinicians on which treatment modality to be used according to the size of the thrombus.

    Full Text Available The objective was to identify the average total cost (ATC for installing and turning off hemodialysis on patients with central venous catheters. This quantitative, exploratory, and descriptive research, in the mode of a single-case study, was conducted in a public university hospital. The non-probabilistic sample corresponded to the observation of 100 installations and 100 terminations of hemodialysis on 42 patients during 23 days of collection. The ATC was calculated by multiplying the time spent by nurses by the unit cost of direct labor, and adding the cost of materials, solutions, and medications. The Brazilian currency (R$ was used for the calculations. The ATC for installation was R$ 80.10 and for shutting off was R$ 13.04, totaling R$ 93.14 per hemodialysis session. The results obtained will facilitate a better planning of the allocation of human, material, and financial resources enabling the increase of managerial strategies aimed at economic efficiency. doi: 10.5216/ree.v16i4.23044.

    Full Text Available Abstract Thromboembolism is a major cause of death in cancer patients. The association between paraneoplastic hypercoagulability of oncological patients and long-term central venous catheters (CVC may result in CVC associated thrombosis. Patent Foramen Ovale (PFO, especially when associated with atrial septal aneurysm (ASA is a risk factor for paradoxical embolism. We report a case of paradoxical embolism with stroke in an oncological patient with a huge CVC thrombus playing "ping-pong" with an hypermobile ASA with a PFO. We review the management of hypercoagulability in oncologic patients and discuss the potential role of routine transthoracic echocardiography before the implantation of long term central venous catheters to identify predisposing conditions to paradoxical embolism and select patients for anticoagulant therapy.

    Central venous catheters (CVCs) are commonly used for the administration of intravenous chemotherapy in outpatient setting. Nevertheless, outbreaks of catheter-associated bloodstream infections had been reported from oncology centers. We describe a large outbreak of CVCs-associated Klebsiella oxytoca bloodstream infection, occurring in an oncology chemotherapy outpatient unit of northern Greece between October 2006 and May 2007. The outbreak involved approximately 10% of the patients with CVCs who were receiving home-based chemotherapy, and it represents the second larger outbreak of CVCs-associated BSIs due to Klebsiella oxytoca in oncology outpatient centers. We retrospectively analyzed the chain of investigations and prophylactic/diagnostic measures taken to eradicate the infection: (1) patients' chart audit, (2) estimation of the infection among asymptomatic patients, (3) implementation of the level of awareness of medical and paramedical personnel, (4) collection of samples from environment, medications and infusion materials, (5) critical appraisal of chemotherapeutical schemes and (6) cooperation with peripheral institutions. The isolation of Klebsiella oxytoca in a chemotherapy solution (infusional 5-FU in dextrose 5% solution within a 48 h pump) from a peripheral General Hospital and the prompt transmission of the data to the chemotherapy center played a key role for the management of the infection cluster. This is the first report that evidenced the detection of Klebsiella oxytoca within a chemotherapeutical preparation. Data transmission from peripheral hospitals to the central institution resulted in an important feedback that allowed a better estimation of the infection cluster and more tailored actions for the eradication of the infection.

    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.

    Full Text Available Central line-associated bloodstream infection (CLABSI is the major complication of central venous catheters (CVC. The aim of the study was to test the effectiveness of a hospital-wide strategy on CLABSI reduction. Between 2008 and 2011, all CVCs were observed individually and hospital-wide at a large university-affiliated, tertiary care hospital. CVC insertion training started from the 3rd quarter and a total of 146 physicians employed or newly entering the hospital were trained in simulator workshops. CVC care started from quarter 7 and a total of 1274 nurses were trained by their supervisors using a web-based, modular, e-learning programme. The study included 3952 patients with 6353 CVCs accumulating 61,366 catheter-days. Hospital-wide, 106 patients had 114 CLABSIs with a cumulative incidence of 1.79 infections per 100 catheters. We observed a significant quarterly reduction of the incidence density (incidence rate ratios [95% confidence interval]: 0.92 [0.88-0.96]; P<0.001 after adjusting for multiple confounders. The incidence densities (n/1000 catheter-days in the first and last study year were 2.3/1000 and 0.7/1000 hospital-wide, 1.7/1000 and 0.4/1000 in the intensive care units, and 2.7/1000 and 0.9/1000 in non-intensive care settings, respectively. Median time-to-infection was 15 days (Interquartile range, 8-22. Our findings suggest that clinically relevant reduction of hospital-wide CLABSI was reached with a comprehensive, multidisciplinary and multimodal quality improvement programme including aspects of behavioural change and key principles of good implementation practice. This is one of the first multimodal, multidisciplinary, hospital-wide training strategies successfully reducing CLABSI.

    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.

    After the insertion of a central venous catheter, a chest radiograph is usually obtained to ensure correct positioning of the catheter tip. To determine in a paediatric population whether B-mode and colour Doppler sonography after central venous access is useful to evaluate catheter position, thus obviating the need for a postprocedural radiograph. A prospective study of 107 consecutive central venous access procedures placed in a paediatric intensive care unit was performed. At the end of the procedure, B-mode and colour Doppler sonography were used to assess catheter position and check for complications. A postprocedural chest radiograph was obtained in all patients. In 96 patients postprocedural B-mode and colour Doppler sonography showed colour Doppler signals within the vena cava. Among the 11 patients predicted to have a potential complication, there was one pneumothorax and ten malpositions. Chest radiography showed a total of 13 complications - 1 pneumothorax and 12 malpositions. The concordance between colour Doppler sonography and chest radiography was 98.1% in the detection of catheter position; sonography had a sensitivity of 84.6% and a specificity of 100%. The close concordance between B-mode and colour Doppler sonography and chest radiography justifies the more frequent use of sonography to evaluate catheter position because ionizing radiation is eliminated. Chest radiography may then be performed only when there is suspected inappropriate catheter tip position after sonography. (orig.)

    Full Text Available Backgound and Objectives: Infections related to central venous catheter (CVC use constitute an important a problem. It is estimated that approximately 90% of bloodstream infections (BSI are caused by CVC use. This study aims at reviewing the risk factors and current recommendations for prevention of infections associated with central venous catheter use. Methods: A total of 12 articles published in the last 5 years and indexed in the databases of the Latin American and Caribbean Literature on Health Sciences (LILACS, Nursing Database (BDENF, International Literature on Health Sciences (Medline/Pubmed were selected, as well as publications related to the recommendations for BSI prevention, such as: Institute for Healthcare Improvement (IHI, Centers for Disease Control and Prevention (CDC and the National Health Surveillance Agency (ANVISA. Results: Two categories were identified: prevention and control measures and risk factors for BSI associated with central venous catheter use. Conclusions: Some recommendations that were well-defined over the years have been questioned by some authors and continuing training and education of the multidisciplinary team are the most important factors for the prevention of bloodstream infections associated with CVC use.

    Background Several million subclavian-vein catheters are placed in patients each year to enable caregivers to administer chemotherapy, total parenteral nutrition, or long-term antibiotics or to manage preoperative fluids. Subclavian venipuncture requires the position of a deep vein to be identified with only surface landmarks. But the traditional right subclavian vein (RSV) catheterization (primitive procedures) is not the answer for all patients. The precise location of the vein is not known, and it is important to select the most appropriate method to achieve central venous access safely in any given patient. To modify the primitive procedures of the RSV catheterization for greater success and reduce the complications, anatomic studies and ultrasonography were conducted and clinical applications were validated.Methods Anatomical observation and measurement of the RSV and its adjacent structures were performed on 20 adult cadavers according to modified procedures. The RSV catheterization of 2900 cases was carried out by the modified procedure, 500 of these cases were observed by ultrasonography after the operation.Results The anatomical studies and clinical application showed that the insertion point differs from the bodily form of fatness or leptosome. The clinical data revealed that in the 2900 cases which were performed with the modified approach, the success rate was 98.90% (2868 cases), the failure rate was 1.10% (32 cases), and the complication rate is 0.79% (23 cases), and the catheterization time is (31.2±10.5) minutes. Five hundred and sixty cases of the RSV catheterization were carried out by the recommended insertion procedure; the results were compared with the modified approach and the traditional approach. The successful rate of the traditional approach was 73.0%, of which the complication rate was 6.1%; the two approaches were significantly different (successful rate: χ2=626.642, P<0.01; complication rate: χ2=80.708, P<0.01).Conclusions The

    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.

    Maintenance of functioning venous access is recognized as the Achilles heel of long-term hemodialysis treatment. In patients who require catheter-directed hemodialysis, the internal jugular veins are recognized as the optimal veins for insertion of dialysis catheters. When these sites are no longer available, alternative venous access sites are required. The authors describe two hemodialysis patients with limited access sites in whom hemodialysis catheters were successfully inserted directly into the innominate veins with use of ultrasound-guided punctures.

    ABSTRACT Introduction: Central Venous Catheters (CVC) are essential in everyday medical practice, especially in treating patients in intensive care units (ICU). The application of these catheters is accompanied with the risk of complications, such as the complications caused during the CVC insertion, infections at the location of the insertion, and complications during the use of the catheter, sepsis and other metastatic infections. Patients and methods: This study is a retrospective-prospective and it was implemented in the period 1st January 2011- 31st December 2012. It included 108 examinees with CVC placed for more than 7 days. Results: The most common complications occurring in more than 2 attempts of CVC applications are: hearth arrhythmias in both groups in 12 cases, 7 in multi-lumen (12.72%) and 5 in mono-lumen ones (9.43%). Artery puncture occurs in both groups in 7 cases, 5 in multi-lumen (9.09%) and 2 in mono-lumen ones (3.77%). Hematoma occurred in both groups in 4 cases, 3 in multi-lumen CVCs (5.45%) and 1 in mono-lumen ones (1.88%). The most common complication in multi-lumen catheters was heart arrhythmia, in 20 cases (36.37%). The most common complications in mono-lumen CVCs was hearth arrhythmias, in 20 cases as extrasystoles and they were registered in 16 catheter insertions (30.18%). Out of total number of catheters of both groups, out of 108 catheters the complications during insertion occurred in 49 catheters (45.40%). The most common complications in both groups were heart arrhythmias, artery punctures and hematomas at the place of catheter insertion. PMID:25568558

    Prescription of thromboprophylaxis is not a common practice in pediatric intensive care units. Most thrombi are catheter-related and asymptomatic, without causing acute complications. However, chronic complications of these (a)symptomatic catheter-related thrombi, that is, postthrombotic syndrome (PTS) and residual thrombosis have not been studied. To investigate these complications, critically ill children of 1 tertiary center with percutaneous inserted femoral central venous catheters (FCVCs) were prospectively followed. Symptomatic FCVC-thrombosis occurred in 10 of the 134 children (7.5%; 95% confidence interval [CI], 2.4-9.5). Only FCVC-infection appeared to be independently associated (P=0.001) with FCVC-thrombosis. At follow-up 2 of the 5 survivors diagnosed with symptomatic thrombosis developed mild PTS; one of them had an occluded vein on ultrasonography. A survivor without PTS had a partial occluded vein at follow-up. Asymptomatic FCVC-thrombosis occurred in 3 of the 42 children (7.1%; 95% CI, 0.0-16.7) screened by ultrasonography within 72 hours after catheter removal. At follow-up, mild PTS was present in 6 of the 33 (18.2%; 95% CI, 6.1-30.3) screened children. Partial and total vein occlusion was present in 1 (3%) and 4 (12%) children, respectively. In conclusion, children on pediatric intensive care units are at risk for (a)symptomatic FCVC-thrombosis, especially children with FCVC-infection. Chronic complications of FCVC-thrombosis are common. Therefore, thromboprophylaxis guidelines are warranted in pediatric intensive care units to minimize morbidity as a result of FCVC-thrombosis.

    Present guidelines recommend culturing only central venous catheter (CVC) tips from patients with suspected catheter-related bloodstream infection (CR-BSI). However, a high proportion of these suspicions are not confirmed. Moreover, CVC tip culture increases laboratory workload, and reports of colonization may be meaningless or misleading for the clinician. Our working hypothesis was that CVC tips should be refrigerated and cultured only in patients with positive blood cultures. We evaluated the effect of 6-day refrigeration of 215 CVC tips. We selected all the catheters with a significant count according to the Maki's roll-plate technique and randomly assigned them to 2 groups. In group A, the catheters were recultured after 24 h of refrigeration, and in group B, the catheters were recultured after 6 days more of refrigeration, so that the refrigeration time evaluated would be of 6 days. The yield of refrigerated CVC tips that grow significant colony counts of primary culture in group B was compared with the yield of refrigerated catheter tips in group A. The difference showed that 6-day refrigeration reduced the number of significant CVCs by 15.2%. Only 61 CVCs were obtained from patients with CR-BSI, and in most of them, blood cultures were already positive before CVC culture, so only 0.91% of the CR-BSI episodes would have been misdiagnosed as culture negative after refrigeration. Refrigeration of CVC tips sent for culture and culturing only those from patients with positive blood cultures reduce the workload in the microbiology laboratory without misdiagnosing CR-BSI.

    Children who require long-term parenteral nutrition (PN) have central venous catheters (CVCs) in place to allow the safe and effective infusion of life-sustaining fluids and nutrition. Many consider recreational swimming to be a common part of childhood, but for some, the risk may outweigh the benefit. Children with CVCs may be at increased risk of exit site, tunnel, and catheter-related bloodstream infections (CRBSIs) if these catheters are immersed in water. The purpose of this review is to evaluate the current literature regarding the risk of infection for patients with CVCs who swim and determine if there is consensus among home PN (HPN) programs on this controversial issue. A total 45 articles were reviewed and 16 pediatric HPN programs were surveyed regarding swimming and CVCs. Due to the limited data available, a firm recommendation cannot be made. Recreational water associated outbreaks are well documented in the general public, as is the presence of human pathogens even in chlorinated swimming pools. As a medical team, practitioners can provide information and education regarding the potential risk, but ultimately the decision lies with the parents. If the parents decide swimming is worth the risk, they are encouraged to use products designed for this use and to change their child's dressing immediately after swimming. Due to our experience with a fatal event immediately after swimming, we continue to strongly discourage patients with CVCs from swimming. Further large and well-designed studies regarding the risk of swimming with a CVC are needed to make a strong, evidence-based recommendation.

    Full Text Available Background: Central venous cannulation (CVC is frequently required during the management of patients with liver disease with deranged conventional coagulation parameters (CCP. Since CVC is known to be associated with vascular complications, it is standard practice to transfuse Fresh-Frozen Plasma or platelets to correct CCP. These CCP may not reflect true coagulopathy in liver disease. Additionally CVC when performed under ultrasound guidance (USG-CVC in itself reduces the incidence of complications. Aim: To assess the safety of USG-CVC and to evaluate the incidence of complications among liver disease patients with coagulopathy. Setting and Design: An audit of all USG-CVCs was performed among adult patients with liver disease in a tertiary care center. Materials and Methods: Data was collected for all the adult patients (18-60 years of either gender suffering from liver disease who had required USG-CVC. Univariate and multivariate regression analysis was done to identify possible risk factors for complications. Results: The mean age of the patients was 42.1 ± 11.6 years. Mean international normalized ratio was 2.17 ± 1.16 whereas median platelet count was 149.5 (range, 12-683 × 10 9 /L. No major vascular or non-vascular complications were recorded in our patients. Overall incidence of minor vascular complications was 18.6%, of which 13% had significant ooze, 10.3% had hematoma formation and 4.7% had both hematoma and ooze. Arterial puncture and multiple attempts were independent risk factors for superficial hematoma formation whereas low platelet count and presence of ascites were independent risk factors for significant oozing. Conclusion: Ultrasound guidance -CVC in liver disease patients with deranged coagulation is a safe and highly successful modality.

    A randomised, prospective study was conducted to evaluate the impact on central venous catheter (CVC) infection when fluids and lines connected to a CVC were changed using a 'sterile' compared to an 'aseptic, non-touch' technique. The study sought to determine whether there were any differences in CVC tip colonisation (CTC) or CVC-related bacteraemia (CRB) as a result of the technique used for fluid and line changes. In the sterile technique (control) group, fluids and tubing were changed using full sterile technique. In the aseptic, non-touch (experimental) group, fluids and tubing attached to the CVC were changed using only a small sterile drape and a 2-minute clinical hand wash. When the CVC was removed, the tip was sampled and cultured using the semi-quantitative method. Blood cultures were also collected. In all, 111 samples from 79 patients were included in the trial: 61 in the sterile technique group and 50 in the non-touch, aseptic technique group. Results showed a CTC rate of 31 per cent in the control group and 14 per cent in the experimental group, while the CRB rate was 8.2 per cent and 6 per cent respectively. The most common organisms cultured were Staphylococcus aureus and S. epidermis respectively. This study indicates that it is safe to change fluids and lines attached to CVCs using the aseptic, non-touch technique, which has resulted in significant financial savings through less use of equipment and less nursing time required to perform fluid and line changes.

    Central venous access devices (CVADs) aid in the delivery of nutritional support, infusion therapy, and hemodialysis. Maintaining continuous flow through these devices is challenging, because they are susceptible to complications such as thrombi occlusion. Therefore, CVADs may require treatment with anticoagulant or thrombolytic agents. Using these agents as locking solutions has been widely investigated; however, few publications have described the compatibility of the therapeutic with the CVAD itself. The objective of this investigation was to evaluate the in vitro stability and compatibility of a thrombolytic biologic agent, tenecteplase, with various CVAD materials. Tenecteplase was reconstituted to 1 mg/mL with either sterile water for injection or bacteriostatic water for injection (0.9% benzyl alcohol) then incubated in glass vials, polysulfone/silicone vascular access ports, and polyurethane or silicone catheters for up to 96 hours. Biochemical assays including protein monomer, protein one-chain, and in vitro bioactivity were used to assess tenecteplase's compatibility with the investigated diluents and materials every 24 hours. Antimicrobial testing was also performed for up to 28 days on bacteriostatic water for injection-reconstituted samples only. Our results showed tenecteplase to be compatible with both types of diluents (in glass vials) and catheters for up to 72 hours. Furthermore, tenecteplase was compatible with the polysulfone/silicone vascular access ports for up to 24 hours. Finally, bacteriostatic water for injection-reconstituted tenecteplase effectively met USP criteria for the inhibition of growth of micro-organisms. This study serves as an example of a best practice to evaluate the in vitro stability and compatibility of a biologic agent with CVAD materials.

    Full Text Available Introduction: Real-time ultrasound guidance is considered to be the standard of care for central venous access for non-emergent central lines. However, adoption has been slow, in part because of the technical challenges and time required to become proficient. The AxoTrack® system (Soma Access Systems, Greenville, SC is a novel ultrasound guidance system recently cleared for human use by the United States Food and Drug Administration (FDA. Methods: After FDA clearance, the AxoTrack® system was released to three hospitals in the United States. Physicians and nurse practitioners who work in the intensive care unit or emergency department and who place central venous catheters were trained to use the AxoTrack® system. De-identified data about central lines placed in living patients with the AxoTrack® system was prospectively gathered at each of the three hospitals for quality assurance purposes. After institutional review board approval, we consolidated the data for the first five months of use for retrospective review. Results: The AxoTrack® system was used by 22 different health care providers in 50 consecutive patients undergoing central venous cannulation (CVC from September 2012 to February 2013. All patients had successful CVC with the guidance of the AxoTrack® system. All but one patient (98% had successful cannulation on the first site attempted. There were no reported complications, including pneumothorax, hemothorax, arterial puncture or arterial cannulation. Conclusion: The AxoTrack® system was a safe and effective means of CVC that was used by a variety of health care practitioners. [West J Emerg Med. 2014;15(4:536-540.

    Full Text Available Repetitive administration of medication or contrast agents is frequently performed in mice. The introduction of vascular access mini-ports (VAMP for mice allows long-term vascular catheterization, hereby eliminating the need for repeated vessel puncture. With catheter occlusion being the most commonly reported complication of chronic jugular vein catheterization, we tested whether digital subtraction angiography (DSA can be utilized to evaluate VAMP patency in mice.Twenty-three mice underwent catheterization of the jugular vein and subcutaneous implantation of a VAMP. The VAMP was flushed every second day with 50 μL of heparinized saline solution (25 IU/ml. DSA was performed during injection of 100 μL of an iodine based contrast agent using an industrial X-ray inspection system intraoperatively, as well as 7±2 and 14±2 days post implantation.DSA allowed localization of catheter tip position, to rule out dislocation, kinking or occlusion of a microcatheter, and to evaluate parent vessel patency. In addition, we observed different ante- and retrograde collateral flow patterns in case of jugular vein occlusion. More exactly, 30% of animals showed parent vessel occlusion after 7±2 days in our setting. At this time point, nevertheless, all VAMPs verified intravascular contrast administration. After 14±2 days, intravascular contrast injection was verified in 70% of the implanted VAMPs, whereas at this point of time 5 animals had died or were sacrificed and in 2 mice parent vessel occlusion hampered intravascular contrast injection. Notably, no occlusion of the catheter itself was observed.From our observations we conclude DSA to be a fast and valuable minimally invasive tool for investigation of catheter and parent vessel patency and for anatomical studies of collateral blood flow in animals as small as mice.

    Full Text Available Central venous catheters are routinely placed in patients undergoing major surgeries where expected volume and hemodynamic disturbances are likely consequences. The incorrect positioning may give false central venous pressure (CVP readings leading to incorrect volume replacement and other serious complications. 50 American Society of Anaesthesiologists grade II-IV patients aged 18-60 years were selected for right-sided internal jugular vein (IJV catheterization using Seldinger′s technique. In group A, central venous catheterization was done under electrocardiography (ECG guidance. In group B, the catheter was inserted blindly using Peres′ formula of "height (in cm/10". The position of the tip of central venous catheter was confirmed radiologically by postoperative chest X-ray. 92% of patients in group A had radiologically correct positioning of catheter tip i.e. above the carina, while in group B 48% patients had over-insertion of the catheter in to the right atrium. Intra-atrial ECG technique to judge correct tip positioning is simple and economical. It can determine the exact position intraoperatively and can justify a delayed postoperative chest X-ray to confirm CVC line tip placement.

    Circulatory shock is a dangerous medical condition, in which blood flow cannot provide the necessary amount of oxygen to organs and tissues. Currently, its diagnosis and therapy decisions are based on hemodynamic parameters (heart rate, blood pressure, blood gases) and mental status of a patient, which all have low specificity. Measurement of mixed or central venous blood oxygenation via catheters is more reliable, but highly invasive and associated with complications. Our previous studies in healthy volunteers demonstrated that optoacoustic systems provide non-invasive measurement of blood oxygenation in specific vessels, including central veins. Here we report our first results of a clinical study in coronary artery bypass graft (CABG) surgery patients. We used a medical-grade OPO-based optoacoustic system developed in our laboratory to measure in real time blood oxygenation in the internal jugular vein (IJV) of these patients. A clinical ultrasound imaging system (GE Vivid e) was used for IJV localization. Catheters were placed in the IJV as part of routine care and blood samples taken via the catheters were processed with a CO-oximeter. The optoacoustic oxygenation data were compared to the CO-oximeter readings. Good correlation between the noninvasive and invasive measurements was obtained. The results of these studies suggest that the optoacoustic system can provide accurate, noninvasive measurements of central venous oxygenation that can be used for patients with circulatory shock.

    Aim: To determine the agreement and diagnostic accuracy of three-dimensional gadolinium-enhanced magnetic resonance venography (3D-Gd-MRV) in central venous steno-occlusive disease (CVSD) in haemodialysis patients. Materials and methods: Fourteen consecutive haemodialysis patients underwent interventional procedures to evaluate or treat CVSD. 3D-Gd-MRV was performed before the procedures and the results were compared with digital subtraction angiography (DSA). Results: DSA showed >50% stenosis in all 14 patients, 13 of whom were diagnosed correctly using 3D-Gd-MRV. Moderate stenosis was missed at 3D-Gd-MRV in one case whereby the indwelling dialysis central venous catheter may have caused an artefact on the images and hindered the accuracy of the result. The sensitivity of 3D-Gd-MRV in revealing stenosis was 93% (13/14). No complications caused by contrast agent toxicity occurred in any patient. Conclusion: 3D-Gd-MRV employing a non-breath-hold technique is highly sensitive in the diagnosis of CVSD and may be an alternative technique to DSA for the visualization of central veins.

    Full Text Available OBJECTIVES: To identify risk factors for short-term percutaneously inserted central venous catheter-related infections in children and to evaluate the accuracy of a mortality score in predicting the risk of infection. METHOD: After reviewing the charts of patients who developed catheter-related infection in a university hospital's pediatric intensive care unit, we conducted a case-controlled study with 51 pairs. Variables related to patients and to catheter insertion and use were analyzed. Risk factors were defined by logistic regression analysis. The accuracy of the Pediatric Risk of Mortality score to discriminate the risk for infection was tested using the Receiver Operating Characteristic curve. RESULTS: Infection was associated with respiratory failure, patient's length of stay, duration of tracheal intubation, insertion of catheter in the intensive care unit and parenteral nutrition. Insertion site (femoral or internal jugular was unimportant. Multivariate logistic regression analysis identified the following variables. Risk factors included more than one catheter placement (p=0.014 and duration of catheter use (p=0.0013, and protective factors included concomitant antibiotic use (p=0.0005 and an intermittent infusion regimen followed by heparin filling compared to continuous infusion without heparin (p=0.0002. Pediatric Risk of Mortality did not discriminate the risk of infection. CONCLUSIONS: Central parenteral nutrition and central venous catheters should be withdrawn as soon as possible. Femoral vein catheterization carries a risk of infection similar to internal jugular catheterization. The Pediatric Risk of Mortality score should not be used to predict the risk of central catheter-related infections.OBJETIVOS: Identificar fatores de risco para as infecções relacionadas a cateter venoso central de curta permanência, inserido por punção, em crianças e avaliar a eficiência de um escore de mortalidade pediátrica em prever o risco

    Full Text Available A 69 year old woman presented with septic shock secondary to a urinary tract infection. A chest radiograph (Figure 1 done after uneventful placement of a left internal jugular central line showed aberrant position of the catheter. Review of a past contrast-enhanced CT chest (Figure 2 revealed an anomalous pulmonary venous return with a pulmonary vein draining to the brachiocephalic vein. Partial anomalous pulmonary venous return (PAPVR is a rare congenital defect which results in a left-to-right shunt. The prevalence was 0.1% in one retrospective study of 45,538 contrast-enhanced chest CT scans (1.

    Full Text Available La colocación de catéteres centrales por vía venosa subclavia y yugular se puede complicar con la canalización de una arteria o de una vía venosa aberrante. La anomalía más frecuente del desarrollo embriológico de la vena cava es la persistencia de la vena cava superior izquierda (VCSI. La implantación de catéteres en la VCSI se puede sospechar por el recorrido anómalo del mismo en la radiografía de tórax. La gasometría y la curva de presión del vaso permiten descartar una cateterización arterial. La confirmación diagnóstica se obtiene mediante angiografía, ecocardiografía, tomografía computerizada o cardio-resonancia. El médico que implanta habitualmente catéteres venosos centrales, debe estar familiarizado con la anatomía del sistema venoso, sus variantes y sus anomalías, ya que su presencia puede influir en el manejo del paciente.The placement of central catheters through the subclavian and jugular venous path can be complicated by the cannulation of an artery or an aberrant venous path. The most frequent anomaly of the embryological development of the caval vein is the persistence of the left superior vena cava (LSVC. The implantation of catheters in the LSVC can be suspected by its anomalous route in thorax radiography. Gasometry and the pressure curve of the vessel make it possible to rule out an arterial catheterisation. Diagnostic confirmation is obtained through angiography, echocardiography, computerised tomography or cardiac resonance. The doctor who regularly implants central venous catheters must be familiar with the anatomy of the venous system and its variants and anomalies, since their presence might influence the handling of the patient.

METHOD The systematic review followed the principles proposed by the Cochrane Handbook; critical analysis, extraction and synthesis of data were performed by two independent researchers; statistical analysis was performed using the RevMan program 5.2.8. RESULTS Eight randomized controlled trials and one cohort study were included and the results of the meta-analysis showed no difference (RR=0.68, 95% CI=0.41-1.10; p=0.12. Analysis by subgroups showed that there was no difference in fully deployed CVC (RR=1.09, CI 95%=0.53-2.22;p=0.82; Multi-Lumen CVC showed beneficial effects in the heparin group (RR=0.53, CI 95%=0.29-0.95; p=0.03; in Double-Lumen CVC for hemodialysis (RR=1.18, CI 95%=0.08-17.82;p=0.90 and Peripherally inserted CVC (RR=0.14, CI 95%=0.01-2.60; p=0.19 also showed no difference. CONCLUSION Saline solution is sufficient for maintaining patency of the central venous catheter, preventing the risks associated with heparin administration.

    Antimicrobial releasing biomaterial coatings have found application for instance in the fixation of orthopedic joint prostheses and central venous catheters. Most frequently, the release kinetics is such that antimicrobially-effective concentrations are only reached within the first days to weeks after implantation, leaving no local antimicrobial release available when a biomaterial-associated infection occurs later. Here we compare the ad libitum release of chlorhexidine and silver-sulfadiazine from a central venous catheter with their release from a new, on-demand release coating consisting of a temperature-sensitive copolymer of styrene and n-butyl (meth)acrylate. The copolymer can be loaded with an antimicrobial, which is released when the temperature is raised above its glass transition temperature. Ad libitum release of chlorhexidine and silver-sulfadiazine from a commercially-purchased catheter and associated antimicrobial efficacy against Staphylococcus aureus was limited to 16days. Consecutive temperature-triggers of our on-demand coating yielded little or no antimicrobial efficacy of silver-acetate release, but antimicrobially-effective chlorhexidine concentrations were observed over a time period of 60-80days. This attests to the clear advantage of on-demand coatings above ad libitum releasing coatings, that may have released their antimicrobial content before it is actually needed. Importantly, glass transition temperature of chlorhexidine loaded copolymers was lower (48°C) than of silver loaded ones (61°C), facilitating their clinical use.

    To evaluate the safety and efficacy of Hickman catheter placement via the subclavian vein under fluoroscopic guidance with intravenous contrast injection. During an eleven-month period, 187 Hickman catheters were percutaneously placed in 167 consecutive patients in an interventional radiology suite. Subclavian venous puncture was made with injection of contrast medium into the peripheral venous line. After subclavian venous access had been obtained, a subcutaneous tunnel was created using a peel-away sheath or a tunneler. The Hickman catheters were inserted through a peel-away sheath, the distal tip of which was as the junction of the right atrium and the superior vena cava. One hundred and eighty-six Hickman catheters were successfully placed ; the one failure was due to anatomical tortuosity of the vein (0.53%). Complications included one case of subclavian vein occlusion (0.53%) ; three of line occlusion by thrombus (1.6%) ; one of oozing at the suture site (0.53%) ; six of infection or inflammation (3.2%) ; eight of natural removal (4.2%) ; one case of air embolism (0.53%) and two of malposition (0.1%). Major complications such as pneumothorax or arterial puncture leading to mediastinal hemorrhage did not, however, occur. The authors concluded that radiologic Hickman catheter placement offers advantages over traditional approaches in terms of safety, convenience, and time and cost savings.

    Central line-associated bloodstream infection (CLABSIs) is an important healthcare-associated infection in the critical care units. It causes substantial morbidity, mortality and incurs high costs. The use of central venous line (CVL) insertion bundle has been shown to decrease the incidence of CLABSIs. Our aim was to study the impact of CVL insertion bundle on incidence of CLABSI and study the causative microbial agents in an intensive care unit in Kuwait. Surveillance for CLABSI was conducted by trained infection control team using National Health Safety Network (NHSN) case definitions and device days measurement methods. During the intervention period, nursing staff used central line care bundle consisting of (1) hand hygiene by inserter (2) maximal barrier precautions upon insertion by the physician inserting the catheter and sterile drape from head to toe to the patient (3) use of a 2% chlorohexidine gluconate (CHG) in 70% ethanol scrub for the insertion site (4) optimum catheter site selection. (5) Examination of the daily necessity of the central line. During the pre-intervention period, there were 5367 documented catheter-days and 80 CLABSIs, for an incidence density of 14.9 CLABSIs per 1000 catheter-days. After implementation of the interventions, there were 5052 catheter-days and 56 CLABSIs, for an incidence density of 11.08 per 1000 catheter-days. The reduction in the CLABSI/1000 catheter days was not statistically significant (P=0.0859). This study demonstrates that implementation of a central venous catheter post-insertion care bundle was associated with a reduction in CLABSI in an intensive care area setting.

    Introduction: CT perfusion studies play an important role in the early detection as well as in therapy monitoring of vasospasm after subarachnoid hemorrhage. High-flow injections via central venous catheters are not recommended but may sometimes be the only possibility to obtain high-quality images. Materials and methods: We retrospectively analyzed our data for CT perfusions performed with power injection of contrast material with an iodine concentration of 400 mg/ml via the distal 16G lumen of the Arrow three and five lumen central venous catheter with preset flow rates of 5 ml/s. Results: 104 examinations with central venous catheters were evaluated (67 with five lumen and 37 with three lumen). No complications were observed. Mean flow rates were 4.4 {+-} 0.5 ml/s using the three lumen catheter and 4.6 {+-} 0.6 ml/s using the five lumen catheter respectively. The mean injection pressure measured by the power injector was 200.7 {+-} 17.5 psi for the three lumen central venous catheter and 194.5 {+-} 6.5 psi for the five lumen catheter, respectively. Conclusion: Following a strict safety protocol there were no complications associated with power injections of contrast material containing 400 mg iodine/ml with preset flow rates up to 5 ml/s via the distal 16G lumen of the Arrow multi-lumen central venous catheter. However, since power-injections are off-label use with Arrow central venous catheters, this procedure cannot be recommended until potential safety hazards have been ruled out by the manufacturer.

    Full Text Available Abstract Background Catheters are the most common cause of nosocomial infections and are associated with increased risk of mortality, length of hospital stay and cost. Prevention of infections and fast and correct diagnosis is highly important. Methods In this study traditional semiquantitative culture-dependent methods for diagnosis of bacteria involved in central venous catheter-related infections as described by Maki were compared with the following culture-independent molecular biological methods: Clone libraries, denaturant gradient gel electrophoresis, phylogeny and fluorescence in situ hybridization. Results In accordance with previous studies, the cultivation of central venous catheters from 18 patients revealed that S. epidermidis and other coagulase-negative staphylococci were most abundant and that a few other microorganisms such as P. aeruginosa and K. pneumoniae occasionally were found on the catheters. The molecular analysis using clone libraries and sequencing, denaturant gradient gel electrophoresis and sequencing provided several important results. The species found by cultivation were confirmed by molecular methods. However, many other bacteria belonging to the phyla Proteobacteria, Firmicutes, Actinobacteria and Bacteroidetes were also found, stressing that only a minor portion of the species present were found by cultivation. Some of these bacteria are known to be pathogens, some have not before been described in relation to human health, and some were not closely related to known pathogens and may represent new pathogenic species. Furthermore, there was a clear difference between the bacterial species found in biofilm on the external (exluminal and internal (luminal side of the central venous catheter, which can not be detected by Maki's method. Polymicrobial biofilms were observed on most of the catheters and were much more common than the cultivation-dependent methods indicated. Conclusion The results show that diagnosis

    Objective To discuss the use of central venous catheter under the intravenous electrocardiogram (IVECC). Methods 150 adult patients who would undergo selective operation of central venous catheterizations in general anesthesia were randomly divided into three groups, group A, B and C (n =50). Patients in group A received dexter internal jugular vein catheter-ization, patients in group B received dexter subclavian vein catheterization and in group C the dexter subclavian vein punctured and catheterization were performed. IVECC monitoring technology was applied in the three groups. We recorded the data of Lmax, Lact, Lpre and the value of Lmax - Lact and Lpre - Lmax respectively. The anteroposterior position of the X-ray examination after operation was taken to judge whether the catheter was in the right place or not. The standard of over-deep or ectopic for atrium dextrum was Lpre - Lmax ≥0.5 cm. Results 146 patients underwent paracentesis successfully, and 4 patients including one from group A, one from group B and two from group C failed in paracentesis. The average indexes of Lmax - Lact and Lpre - Lact were (2.4 ± 0.3) cm and(2.1 ±0.8)cm respectively in the 146 patients. There were 22 patients with Lpre -Lmax≥0. 5 cm (15.07% ) , including 7 patients in group A, 8 patients in group B and 7 patients in group C. The typical change was catheter tip being located at superior vena cava according to chest X-ray film postoperative. According to the results of IVECG and chest X-ray film, the patients with Lpre -Lmax≥0.5 cm canal were located in atrium dextrum and catheter placement coincidence rate was 100%.

    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.

    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.

    Central venous catheters (CVC) are frequently used in intensive care units (ICU), with a low incidence of complications, most of them being of mechanical origin and occurring during the insertion of the catheter. To avoid such complications, "ultrasound guidance" and "ultrasound assistance" are recommended. Nevertheless, even with trained and experienced physicians, mechanical complications of IJV access such as carotid punctures are still reported. We report the case of a 75-year-old woman, admitted into the ICU for CVC insertion due to impossibility of peripheral venous access. About 12 hours after the procedure, the patient presented a neurological deficit. The cervical and thoracic CT scan showed a transfixing path of the catheter from the left IJV into the left common carotid artery, with distal extremity of the catheter localized in the ascending aorta. The catheter was removed, and thereafter the neurological deficit immediately and definitely disappeared. Onset of a neurological deficit after CVC insertion into the IJV, regardless the time of occurrence after the procedure, should suggest complication due to the CVC insertion, even if procedure was uneventful and chest radiography confirmed the apparent accurate position of CVC.

    Objective In acute respiratory distress syndrome (ARDS), conservative fluid management increases ventilator-free days without affecting mortality. Response to fluid management may differ based on patients’ initial central venous pressure (CVP). We hypothesized initial CVP would modify the effect of fluid management on outcomes. Design Retrospective analysis of the Fluid and Catheter Treatment Trial, a multicenter randomized trial comparing conservative to liberal fluid management in ARDS. We examined the relationship between initial CVP, fluid strategy, and 60-day mortality in univariate and multivariable analysis. Setting Twenty acute care hospitals. Patients Nine hundred and thirty-four ventilated ARDS patients with a CVP available at enrollment, 609 without baseline shock (for whom fluid balance was managed by study protocol). Interventions None. Measurements and Main Results Among patients without baseline shock, those with initial CVP > 8 mmHg experienced similar mortality with conservative and liberal fluid management (18% versus 18%, p=0.928), whereas those with CVP ≤8 mmHg experienced lower mortality with a conservative strategy (17% versus 36%, p=0.005). Multivariable analysis demonstrated an interaction between initial CVP and the effect of fluid strategy on mortality (p=0.031). At higher initial CVPs, the difference in treatment between arms was predominantly furosemide administration, which was not associated with mortality (p=0.122). At lower initial CVPs, the difference between arms was predominantly fluid administration, with additional fluid associated with increased mortality (p=0.013). Conclusions Conservative fluid management decreases mortality for ARDS patients with a low initial central venous pressure. In this population, the administration of intravenous fluids appears to increase mortality. PMID:26741580

    Full Text Available Abstract Background This study assesses the impact that a resident oversight and credentialing policy for central venous catheter (CVC placement had on institution-wide central line associated bloodstream infections (CLABSI. We therefore investigated the rate of CLABSI per 1,000 line days during the 12 months before and after implementation of the policy. Methods This is a retrospective analysis of prospectively collected data at an academic medical center with four adult ICUs and a pediatric ICU. All patients undergoing non-tunneled CVC placement were included in the study. Data was collected on CLABSI, line days, and serious adverse events in the year prior to and following policy implementation on 9/01/08. Results A total of 813 supervised central lines were self-reported by residents in four departments. Statistical analysis was performed using paired Wilcoxon signed rank tests. There were reductions in median CLABSI rate (3.52 vs. 2.26; p = 0.015, number of CLBSI per month (16.0 to 10.0; p = 0.012, and line days (4495 vs. 4193; p = 0.019. No serious adverse events reported to the Pennsylvania Patient Safety Authority. Conclusions Implementation of a new CVC resident oversight and credentialing policy has been significantly associated with an institution-wide reduction in the rate of CLABSI per 1,000 central line days and total central line days. No serious adverse events were reported. Similar resident oversight policies may benefit other teaching institutions, and support concurrent organizational efforts to reduce hospital acquired infections.

    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.)

    In 99 patients with congenital heart defects or chronic respiratory disease without clinical symptoms of disturbances in peripheral circulation, resting and maximal blood flow in the anterior tibial muscle of both extremities were investigated 2.7 yrs (average) after cardiac catheterization. The method used involved /sup 133/Xe clearance. Resting blood flow was normal and no difference could be demonstrated between the extremity originally used for catheterization and the contralateral control extremity. No disturbance in maximal blood flow could be proved in the extremity used for catheterization by the venous route only. Maximal blood flow was significantly lower in that extremity where the femoral artery had been catheterized or cannulated for pressure measurement and blood sampling. The disturbance in maximal flow was shown regardless of whether the arterial catheterization involved the Seldinger percutaneous technique, arteriotomy, or mere cannulation of the femoral artery. The values in the involved extremity did not differ significantly from the values in a healthy population.

    2008-11-01

    Full Text Available Objectives: This study describes a means of assessing the external jugular venous pressure (JVP as an indicator of normal or elevated central venous pressure (CVP.Methods: Intensive care unit patients having CVP monitoring were examined. With patients in bed, the external jugular vein (EJV was occluded at the base of the neck and observed to distend. The occlusion was then removed and the vein observed for collapse. Complete collapse was hypothesized to indicate a non-elevated CVP (≤8cm of water. In those patients whose EJV collapsed incompletely, the vein was then occluded with the finger near the angle of the jaw. With the occlusion maintained, the vein was milked downwards with the other hand to cause its emptying and was then observed for filling from below. Filling from below was hypothesized to indicate an elevated CVP (>8cm of water.Results: In 12 of the 40 patients examined, the EJV could not be assessed (EJV not seen at all: 5, and difficult to visualize: 7. For the remaining 28 patients, 11 had a CVP > 8 cm, while 17 had a CVP of < 8. EJV assessment was 100% accurate (95% Confidence Interval 88-100 in predicting whether or not a patient’s CVP was greater or less than 8 cm of water.Conclusion: EJV assessment, when visible, is accurate to clinically assess a patient’s CVP in the hands of the author. Further studies are needed to see if they are reproducible by other observer.[WestJEM. 2008;9:201-205.

    Catheter-related bloodstream infection (CRBSI) is an infectious disease requiring special attention. It is a common cause of nosocomial infections; catheter insertion into the central veins particularly increases the risk of infection (CLA-BSI: central line-associated bloodstream infection). We examined the relationship between the number of bacterial colonies cultured from shredded central venous catheter (CVC) tips and from blood cultures in our hospital from 2011 to 2012. Coagulase-negative staphylococci topped the list of microbe isolated from the CVC tip culture, followed by Pseudomonas aeruginosa, Staphylococcus aureus, and Candida spp. S. aureus and Candida spp., with growth of over 15 colony-forming units in the CVC tip culture, were also detected at high rates in the blood culture. However, gramnegative bacilli (Enterobacteriaceae and P. aeruginosa) did not show a similar increase in colony number in the CVC tip culture. Because microbes adhering to shredded catheter tips are readily detected by culture, this method is useful as a routine diagnostic test. In addition, prompt clinical reporting of the bacterial number of serious CLA-BSI-causing S. aureus and Candida spp. isolated from CVC tips could contribute to earlier CLA-BSI diagnosis.

    Full Text Available Background: The aim of the present study was to evaluate the rejuvenation capacity among cardiac catheterization technicians occupationally exposed to ionizing radiation. Subjects and methods: The individual annual collective dose information was measured by thermoluminscent personal dosimeters (TLD for those technicians and found to be ranging between 2.16 and 8.44 mSv/y. Venous blood samples were obtained from 30 cardiac catheterization technicians exposed to X-ray during fluoroscopy procedures at the National Heart Institute in Embaba. The control group involved 25 persons not exposed to ionizing radiation and not working in hospitals in addition to 20 persons not exposed to ionizing radiation and working in hospitals. Blood samples were assayed for total and differential blood counts, micronucleus formation (FMN plasma stromal derived growth factor-1α (SDF-1 α and cell phenotype of circulating endothelial progenitor cells (EPCs, whose surface markers were identified as the CD34, CD133 and kinase domain receptors (KDR. Results: SDF-1α (2650± 270 vs. 2170 ± 430 pg/ml and FMN (19.9 ± 5.5 vs. 2.8 ± 1.4/1000 cells were significantly higher among cardiac catheterization staff compared to those of the controls respectively. Similarly, EPCs: CD34 (53 ± 3.9 vs. 48 ± 8.5/105 mononuclear cells, CD133 (62.4 ± 4.8 vs. 54.2 ± 10.6 /105 mononuclear cells KDR (52.7 ± 10.6 vs.43.5± 8.2 /105 mononuclear cells were also significantly higher among cardiac catheterization staff compared to the values of controls respectively. Smoking seemed to have a positive effect on the FMN and SDF-1 but had a negative effect on EPCs. It was found that among cardiac catheterization staff, the numbers of circulating progenitor cells had increased and accordingly there was an increased capacity for tissue repair. Conclusion: In conclusion, the present work shows that occupational exposure to radiation, well within permissible levels, leaves a genetic mark on the

    When metal clips and venous catheters have been used the computerized tomography shows artifacts, which make it computerized tomography shows artifacts, which make it difficult to have a reliable and accurate diagnosis, because the X- raying of the metal clips and the venous catheter gives radiating lines, so called streaking. We have tested new materials for the metal clips and a new polymer to replace the substance of the venous catheter with the intention that the materials should have the same density as the normal tissues. With a new metal for the clips and a new polymer for the venous catheters, mixed with metal ions, the computerized tomography does not show streaking.

    Blood viscosity is an important determinant of microvascular hemodynamics and also reflects systemic inflammation. Viscosity of blood strongly depends on the shear rate and can be characterized by a two parameter power-law model. Other major determinants of blood viscosity are hematocrit, level of inflammatory proteins and temperature. In-vitro studies have shown that these major parameters are related to the electrical impedance of blood. A special central venous catheter was developed to measure electrical impedance of blood in-vivo in the right atrium. Considering that blood viscosity plays an important role in cerebral blood flow, we investigated the feasibility to monitor blood viscosity by electrical bioimpedance in 10 patients during the first 3 days after successful resuscitation from a cardiac arrest. The blood viscosity-shear rate relationship was obtained from arterial blood samples analyzed using a standard viscosity meter. Non-linear regression analysis resulted in the following equation to estimate in-vivo blood viscosity (Viscosity(imp)) from plasma resistance (R(p)), intracellular resistance (R(i)) and blood temperature (T) as obtained from right atrium impedance measurements: Viscosity(imp)=(-15.574+15.576R(p)T)SR ((-.138RpT-.290Ri)). This model explains 89.2% (R(2)=.892) of the blood viscosity-shear rate relationship. The explained variance was similar for the non-linear regression model estimating blood viscosity from its major determinants hematocrit and the level of fibrinogen and C-reactive protein (R(2)=.884). Bland-Altman analysis showed a bias between the in-vitro viscosity measurement and the in-vivo impedance model of .04 mPa s at a shear rate of 5.5s(-1) with limits of agreement between -1.69 mPa s and 1.78 mPa s. In conclusion, this study demonstrates the proof of principle to monitor blood viscosity continuously in the human right atrium by a dedicated central venous catheter equipped with an impedance measuring device.

    STUDY OBJECTIVE: To determine the analgesic efficacy of three different rates of remifentanil infusion in patients undergoing insertion or removal of long-term central venous access devices during monitored anesthesia care and local anesthetic field infiltration. DESIGN: Double-blinded, randomized, controlled study. SETTING: Operating theatre of an University hospital. PATIENTS: 44 unpremedicated, ASA physical status 1 and 2 patients, aged 18-65 years, undergoing insertion or removal of a Port-a-Cath or Hickman catheter. INTERVENTIONS: Patients sedated with a propofol target-controlled infusion were randomly allocated to three groups: Group R25 (n = 14), Group R50 (n = 15), and Group R75 (n = 15), to receive remifentanil 0.025, 0.05, and 0.075 mug\\/kg\\/min, respectively. Rescue remifentanil 0.5 mug\\/kg was administered for pain scores > 3. The remifentanil infusion rate was maintained constant unless respiratory and\\/or cardiovascular unwanted events occurred, whereupon the rate was adjusted in 0.01 mug\\/kg\\/min decrements as necessary. MEASUREMENTS: Pain scores (primary outcome), sedation, and movement scores (secondary outcomes) were assessed during local anesthetic infiltration of the anterior chest wall and 5 other procedural steps. MAIN RESULTS: All infusion rates had equal analgesic efficacy, as shown by comparable pain scores, number of rescue boluses, and number of patients requiring rescue analgesia. Excessive sedation was associated with the highest remifentanil rate such that Group R75 patients were significantly more sedated than Groups R25 or R50 at selective procedural steps (P < 0.05). More Group R75 patients (6\\/15) required remifentanil rate reduction than did patients from Group R50 (1\\/15) or Group R25 (0\\/14), P < 0.01, most commonly because of respiratory depression. CONCLUSIONS: For the insertion or removal of long-term central venous access devices, all three remifentanil infusion rates proved to be equally analgesic

    To assess the technical success and complication rates of the radiologic placement of central venous ports via the internal jugular vein. We retrospectively reviewed 1254 central venous ports implanted at our institution between August 2002 and October 2009. All procedures were guided by using ultrasound and fluoroscopy. Catheter maintenance days, technical success rates, peri-procedural, as well as early and late complication rates were evaluated based on the interventional radiologic reports and patient medical records. A total of 433386 catheter maintenance days (mean, 350 days; range 0-1165 days) were recorded. The technical success rate was 99.9% and a total of 61 complications occurred (5%), resulting in a post-procedural complication rate of 0.129 of 1000 catheter days. Among them, peri-procedural complications within 24 hours occurred in five patients (0.4%). There were 56 post-procedural complications including 24 (1.9%, 0.055 of 1000 catheter days) early and 32 (2.6%, 0.074 of 1000 catheter days) late complications including, infection (0.6%, 0.018 of 10000 catheter days), thrombotic malfunction (1.4%, 0.040 of 1000 catheter days), nonthrombotic malfunction (0.9%, 0.025 of 1000 catheter days), venous thrombosis (0.5%, 0.014 of 1000 catheter days), as well as wound problems (1.1%, 0.032 of 1000 catheter days). Thirty six CVPs (3%) were removed due to complications. Bloodstream infections and venous thrombosis were the two main adverse events prolonging hospitalization (mean 13 days and 5 days, respectively). Radiologic placement of a central venous port via the internal jugular vein is safe and efficient as evidenced by its high technical success rate and a very low complication rate.

    Full Text Available OBJECTIVES: The purpose of present study was to evaluate the reliability of central venous blood gas monitoring as an alternative to arterial blood gas monitoring and to assess that the central venous catheter is convenient and reliable source of blood for repetitive measurement of pH bicarbonate and PCO2 in critically ill patients admitted in surgical intensive care unit (SICU. METHODS: We took one hundred patients who required ABG analysis between 20 - 60 years of age. The cases were divided in four groups which constituted major admissions in SICU in one year. Out of one hundred patients for the study there were 19 Poisoning patients, 15 Trauma patients, 40 Major abdominal surgery patients, 26 Hypovolemic shock patients and others. Central Venous blood drawn within 5 min of an ABG measurement and the samples analyzed immediately on automated ABG analyzer were compared. RESULTS: Bland Altman plots demonstrated a high degree of agreement between the two corresponding sets of measurements of arterial and venous blood with coefficient of correlation 0.979 for pH. The coefficient of correlation was highly positive i.e. 0.926 for PCO 2 and 0.955 for HCO 3 - which is statistically significant. There was also positive correlation for saturation between arterial and venous blood i.e. 0.57 with clinically acceptable difference and is statistically significant. The difference in pO 2 measurements was however higher with correlation coefficient of 0.259 although the arterial saturation and finger oximetry reveals a good degree of agreement with clinically acceptable bias. CONCLUSION: Venous blood gas (VBG analysis clearly does not replace ABG analysis in determining exact pO 2 status and arterial puncture may still be required for invasive arterial BP monitoring. With positive correlation and regression plots obtained, venous samples can be used as an alternative to arterial samples depending on the significant positive correlation values obtained for

    Central venous access device (CVAD) insertion is one of the most common procedures performed on paediatric haemophilia patients. There are no clear guidelines outlining the optimal dosing schedule of factor VIII (FVIII) and duration of treatment required to achieve adequate haemostasis during and after surgery. In this article, we describe the experience at McMaster Children's Hospital using FVIII replacement therapy in 15 children with severe haemophilia A during the course of 7 years. This is a retrospective institutional chart review. Patients between 0 and 18 years of age with severe haemophilia A that underwent CVAD insertion at McMaster Children's Hospital in Hamilton, Ontario, from 2004 to 2010, were identified and charts were reviewed. A total of 15 CVAD insertion surgeries were reviewed. The total average preoperative dose of FVIII was 93.5 IU/kg (range: 53.7-145.4 IU/kg). The total average postoperative dose was 818.7 IU/kg (range: 441-1258 IU/kg). The total perioperative dose was 912.2 IU/kg (range: 495.2-1349 IU/kg). The current study attempts to describe the experience at McMaster Children's Hospital for CVAD insertion surgeries, the average factor dose administered has decreased during the years. These results may be of help in the development of optimal treatment schedules.

    Central venous port devices made of two different polymeric materials, thermoplastic polyurethane (TPU) and silicone rubber (SiR), were compared due their material properties. Both naïve catheters as well as catheters after removal from patients were investigated. In lab experiments the influence of various chemo-therapeutic solutions on material properties was investigated, whereas the samples after removal were compared according to the implanted time in patient. The macroscopic, mechanical performance was assessed with dynamic, specially adapted tests for elasticity. The degradation status of the materials was determined with common tools of polymer characterisation, such as infrared spectroscopy, molecular weight measurements and various methods of thermal analysis. The surface morphology was analysed using scanning electron microscopy. A correlation between material properties and clinical performance was proposed. The surface morphology and chemical composition of the polyurethane catheter materials can potentially result in increased susceptibility of the catheter to bloodstream infections and thrombotic complications. The higher mechanic failure, especially with increasing implantation time of the silicone catheters is related to the lower mechanical performance compared to the polyurethane material as well as loss of barium sulphate filler particles near the surface of the catheter. This results in preformed microscopic notches, which act as predetermined sites of fracture.

Results Mean time insitu for intraports was 164∀35 days. Median follow-up time was 290 days and total port time in situ was 40180 days. The incidence of port rupture was 1 per 10,000 port days. Three of the 4 cases were managed by successful removal of catheters. In two of these the catheter was removed under fluoroscopic control using femoral route, while in the third patient the catheter (partial rupture was removed surgically. One of the catheters could not be removed and migrated to right ventricle on manipulations. Conclusion Port catheter rupture is a rare but dreaded complication associated with subcutaneous port catheter device placement for chemotherapy. In case of such an event the patient should be managed by an experienced vascular surgeon and interventional radiologist, as in most cases the ruptured catheter can be retrieved by non operative interventional measures.

    2013-11-01

    Purpose: To evaluate the efficacy and outcome of a flow confirmation study (FCS) in oncologic outpatients undergoing chemotherapy suspected of a central venous port (CVP) system-related mechanical complication. Materials and methods: A total of 66 patients (27 men, 39 women; mean age, 60 years) received FCS for the following reasons: prolonged infusion time during chemotherapy (n = 32), inability to inject saline fluid (n = 15), lateral neck and/or back pain (n = 6), subcutaneous extravasation of anticancer drug (n = 5), arm swelling (n = 4), and inability to puncture the port (n = 4). FCS consisted of examining the position of CVP, potential secondary shifts or fractures, and integrity of the system using contrast material through the port. Results: Of the 66 patients, 43 had an abnormal finding uncovered by FCS. The most frequent abnormal findings was catheter kinking (n = 22). Explantation and reimplantation of the CVP system was required in 21 of the 66 patients. Remaining 45 patients were able continue using the CVP system after the FCS without any system malfunction. Conclusion: FCS was effective for evaluating CVP system-related mechanical complications and was useful for deciding whether CVP system explantation and reimplantation was required.

    Peripherally inserted central catheters (PICCs) are frequently placed at the bedside. The purpose of our study was to evaluate the efficacy of the Sherlock II tip location system (Bard Access Systems, Salt Lake City, UT), which offers electromagnetic detection of the PICC tip to assist the operator in guiding the tip to a desired location. We performed a retrospective review of patients who had a bedside PICC using the Sherlock II tip location system. Three hundred seventy-five of 384 patients (97.7%) had the catheter tip positioned appropriately. Our results suggest that the Sherlock II tip location system is an efficacious system for bedside PICC placement.

    2013-01-01

    Full Text Available The supraclavicular approach was first put into clinical practice in 1965 by Yoffa and is an underused method for gaining central access. It offers several advantages over the conventional infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-sided approach offers a straighter path into the subclavian vein. Also, this site is often more accessible during CPR and surgical procedures. In patients who are obese, this anatomic area is less distorted and in patient with congestive heart failure and cervical spine instability repositioning is not required.

    Full Text Available Background: Catheterization of Internal Jugular Vein (IJV is commonly attempted to obtain central venous access for hemodynamic monitoring, long term administration of fluids, total parenteral nutrition and hemodialysis in critical care patients. The safe puncture of the IJV is achieved by using anatomical land marks on skin surface. Ultrasound guidance could be beneficial in placing central venous catheters by improving the success rate, reducing the number of needle passes, decreasing access time and decreasing complications. Material and Methods: Sixty critical care patients were selected for IJV cannulation either by land mark technique or by ultrasound guided technique in two groups of thirty each. Results: In our study there was 100% success rate for first attempt cannulation in USG technique and where as it was 83.3% in LMG technique. The mean access time in USG technique was 152.50 ± 63.90 sec as against 323.23 ± 146.19 sec in LMG group. Conclusion: Ultrasound guided technique improves the cannulation of the IJV with respect to safety, rapidity and comfort to the patient during the procedure.

    Full Text Available Although central vascular catheters (CVC are indispensable in modern medicine, they are an important risk factor for primary bacteremias. We examined the incidence and risk factors associated with catheter-related bloodstream infection (CR-BSI caused by Staphylococcus aureus in surgical patients. A prospective study was carried out in the Hospital das Clínicas da Universidade Federal de Uberlândia (HC-UFU from September 2000 to December 2002. The skin insertion site, catheter tip, and blood were microbiologically analyzed. Demographics and risk factors were recorded for each patient, and cultures were identified phenotypically. Staphylococcus aureus was the most frequent pathogen, with an incidence rate of 4.9 episodes of CR-BSIs per 1,000 catheter/days. Based on logistic regression, the independent risk factors were: colonization on the insertion site =200 colony forming units (CFU/20 cm² (p=0.03; odds ratio (OR =6.89 and catheter tip (p=0.01; OR=7.95. The CR-BSI rate was high; it was mainly associated with S. aureus, and skin colonization at the insertion site and on the catheter tip were important risk factors for CR-BSI.

    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

    2015-06-01

    Chronic infusion of prostacyclin (PGI2) via a Broviac central venous line (CVL) is attended by risk of CVL-related complications, but we know of only one report regarding CVL-associated bloodstream infection (BSI) with PGI2 in children and none regarding other complications. We conducted a retrospective cohort study involving pediatric patients with pulmonary hypertension treated with chronic intravenous infusion of PGI2 at Boston Children's Hospital and determined the rate (per 1,000 line-days) of various CVL-related complications. We also determined how often complications necessitated line replacement and hospitalization, time to replacement of CVLs, and interpatient variability in the incidence of complications. From 1999 until 2014, 26 patients meeting follow-up criteria had PGI2 infusion, representing 43,855 line-days; mean follow-up was 56 months (range, 1.4-161 months). The CVL complication rates (per 1,000 line-days) were as follows: CVL-BSI, 0.25; superficial line infection, 0.48; impaired integrity, 0.59; occlusion, 0.09; and malposition, 0.32. The total complication rate was 1.73 cases per 1,000 line-days. All CVL-BSI and malposition cases were treated with CVL removal and replacement. Of CVLs with impaired integrity, 23 could be repaired and 3 required replacement. Six of 21 superficial CVL infections required replacement of the CVL. Three of 4 occluded CVLs were replaced. CVL complications occasioned 65 hospitalizations. There was marked interpatient variability in the rate of complications, much but not all of which appeared to be related to duration of CVL placement. We conclude that non-BSI complications are very significant and that efforts to teach and emphasize other aspects of line care are therefore very important.

    Full Text Available Background: Central venous (CV catheters play an essential role in the management of critically ill patients in the Intensive Care Unit (ICU. CV lines are, however, allied to catheter-associated blood stream infections. Bacterial colonization of CV lines is deemed the main cause of catheter-associated infection. The purpose of our study was to compare bacterial colony counts in the catheter site before CV line insertion in two groups of post-cardiac surgery patients: a group receiving Sanosil (an antiseptic agent composed of H2 O2 and silver and a control group.Methods: This interventional prospective double-blinded clinical trial recruited the patients in three post-cardiac surgeryICUs of a heart center. The participants were divided into interventional (113 patients and control (136 patients groups. Sanosil was added to the routine preparation procedure (Chlorhexidine bath one day before and scrub with Povidone-Iodine just before the CV line insertion. After the removal of the CV lines, the catheters tips were sent for culture and evaluation of colony counts.Results: Catheter colonization occurred in 55 (22.1% patients: 26 (23% patients in the Sanosil group and 29 (21.3% in the control group; there was no significant statistical difference between the two groups (p value = 0.75, RR = 1.05, 95%CI:0.76-1.45. The most common organism having colonized in the cultures of the catheter tips was staphylococcus epidermis:20 cases in the control group and 16 cases in the intervention group.Conclusion: Catheter colonization frequently occurs in post-cardiac surgery patients. However, our results did not indicate the effectiveness of adding Sanosil to the routine preparation procedure with respect to reducing catheter bacterial colonization.

    Full Text Available Background: Proper placement of central venous catheter (CVC tip could reduce early and late catheter-related complications. Although the live fluoroscopy is standard of care for placement of the catheter, it is not available in many centers. Therefore, the present study evaluated the sensitivity and specificity of bedside chest X-ray (CXR for proper positioning of the catheter tip. Materials and Methods: A total of 82 adult patients undergoing elective placement of tunneled CVC were enrolled in this study during 2010-2012. The catheter tip position was evaluated by postoperative bedside chest radiographs as well as trans-thoracic echocardiogram as definite diagnostic tool. The catheter position was considered correct if the tip was positioned in the right atrium both in CXR or echocardiography. Finally, CXRs interpreted by expert radiologist. Thus findings were compared by echocardiography. Sensitivity, specificity, accuracy, positive, and negative predictive values were calculated. Data were analyzed using SPSS version 16 (SPSS Inc., Chicago, IL, and P < 0.05 considered as significant. Results: The patients were 57.37 ± 18.91 years of age, weighed 65.79 ± 15.58 kg and were 166.36 ± 9.91 cm tall. Sensitivity and specificity of CXR for proper catheter tip position were 74.3% and 58.3%, respectively. Positive and negative predictive values were 91.2% and 28%. In addition accuracy, positive likelihood ratio, and negative likelihood ratio were 71.9%, 1.78, and 2.27 respectively. Conclusion: Bedside CXR alone does not reliably predict malpositioning after CVC placement.

    Full Text Available Objective: Fluid infusion, the most critical step in the resuscitation of patients with septic shock, needs preferably continuous invasive hemodynamic monitoring. The study was planned to evaluate the efficacy of ultrasonographically measured inferior vena cava collapsibility index (IVC CI in comparison to central venous pressure (CVP in predicting fluid responsiveness in septic shock. Materials and Methods: Thirty-six patients of septic shock requiring ventilatory support (invasive/noninvasive were included. Patients with congestive heart failure, raised intra-abdominal pressure, and poor echo window were excluded from the study. They were randomly divided into two groups based on mode of fluid resuscitation - Group I (CVP and Group II (IVC CI. Primary end-points were mean arterial pressure (MAP of ≥65 mmHg and CVP >12 mmHg or IVC CI <20% in Groups I and II, respectively. Patients were followed till achievement of end-points or maximum of 6 h. Outcome variables (pulse rate, MAP, urine output, pH, base deficit, and ScvO 2 were serially measured till the end of the study. Survival at 2 and 4 weeks was used as secondary end-point. Results: Primary end-point was reached in 31 patients (15 in Group I and 16 in Group II. Fluid infusion, by either method, had increased CVP and decreased IVC CI with resultant negative correlation between them (Pearson correlation coefficient -0.626. There was no significant difference in the amount of fluid infused and time to reach end-point in two groups. Comparison in outcome variables at baseline and end-point showed no significant difference including mortality. Conclusion: CVP and IVC CI are negatively correlated with fluid resuscitation, and both methods can be used for resuscitation, with IVC CI being noninferior to CVP.

    Full Text Available Central venous catheters from intensive care unit patients were subjected to microbiological methods (semiquantitative culture and scanning electron microscopy in order to assess microbial attachment and correlate it with blood cultures. During the period of the survey, 59 patients with inserted central venous catheters were studied. The type of catheter used was nontunneled, noncuffed, single lumen, made of polyurethane. Blood samples for cultures were collected at the moment of catheter removal. Data on the patient's age, gender, catheter insertion site, and duration of catheterization were also obtained. From 63 catheters tips analysed, 30 (47.6% showed microbial colonization. Infection proved to be more prevalent in 26 (41.3% patients with catheters inserted via subclavia vein than in 2 (3.2% inserted via the jugular vein. Infection was observed more frequently in catheters which were kept in place more than seven days. A. baumannii, Citrobacter freundii, E. aerogenes, P. aeruginosa and S. saprohyticus were isolated as causal agents of catheter-related bloodstream infections. The antimicrobial agent with greater in vitro activity against Gram-negative bacteria was imipenen and against Gram-positive were vancomycin, cefepime, penicillin, rifampin and tetracycline. The SEM analyses revealed biofilms on surfaces of all the catheters examined.Cateteres venosos centrais inseridos em pacientes internados em unidade de terapia intensiva foram avaliados por métodos microbiológicos (cultura semi-quantitativa e microscopia eletrônica de varredura a fim de detectar adesão microbiana e correlacionar com a cultura de sangue.

The aim of this study was to determine the performance, pain, and quality of life on use of central venous catheter (CVC for drainage of pericardial effusion in patients undergoing open heart surgery. Fifty-five patients who had developed pericardial effusion after an open heart surgery (2012–2015 were prospectively assessed. Triple-lumen central catheters were inserted under echocardiographic guidance. Clinical, procedural, complication, and outcome details were analyzed. Intensity of pain and quality of life of patients were assessed using the numerical rating scale and Short-Form Health Survey. CVC was inserted for 36 males and 19 females, all of whom had a mean age of 58.5±15 years, and the mean duration of the open heart surgery was 8±3.5 hours. The mean central venous pressure catheter life span was 14.6 days. No cases of recurrent effusion and complication were reported. The technical success rate of procedure was 100%. Intensity of pain and quality of life of patients had improved during follow-up. CVC insertion is a safe and effective technique for the management of pericardial effusion in patients after open heart surgery.

    OBJECTIVE To explore the incidence, etiology, and risk factors of central venous catheter (CVC)-related fungal infections in tumor patients so as to propose the effective prevention measures. METHODS The related factors for infections in 200 tumor patients who underwent CVC from Jan to Oct, 2011 were reviewed retrospectively. RESULTS The incidence of CVC-related fungal infections was 15. 0%. There were 26 cases with single CVC-related infections and 4 cases with fungemia. Candida parapsilosis, Candida tropicalis, Candida ruffle monilia , Candida albicans, and Candida glabrata accounted for 53. 3% , 16. 7% > 13. 3%, 10. 0% and 6. 7% , respectively. The gender, age, types of tumor, and surgery were negatively correlated with the incidence of CVC-related infections, the difference in the infection rates between the different sites of catheterization was statistically significant (P<0. 05), the difference in the catheterization duration between the patients with CVC-related infections was statistically significant(P<0. 05) , totally 26 cases with infections were cured after extuba-tion of CVC, 3 of 4 patients with fungemia were cured after the antifungal treatment, and 1 case died of the mixed pulmonary Candida infections. CONCLUSION Candida parapsilosis is the predominant pathogen causing CVC-related fungal infections in the tumor patients. Timely extubation of CVC can effectively prevent catheter-related blood stream infections.%目的 探讨肿瘤患者中心静脉导管(CVC)真菌感染的分布与发生率,分析其相关因素,提出有效的预防改进措施.方法 回顾性分析2011年1-10月医院留置CVC的200例肿瘤患者的感染情况及相关因素.结果 CVC相关性真菌感染发生率为15.0%,其中26例单纯CVC感染(CVC-RI),4例合并真菌血症,其中近平滑假丝酵母菌、热带假丝酵母菌、皱褶假丝酵母菌、白色假丝酵母菌及光滑假丝酵母菌分别占53.3%、16.7%、13.3%、10.0%及6.7%;CVC感染发

    Full Text Available Background and Aims: Central venous catheters are in situ in most of the intensive care unit (ICU patients, which may be an alternative for determining acid-base status and can reduce complications from prolonged arterial cannulation. The aim of this study was to examine the reliability between adjusted central venous blood gas (aVBG and arterial blood gas (ABG samples for pH, partial pressure of carbon-di-oxide (pCO2, bicarbonate (HCO3−, base excess (BE and lactates in paediatric cardiac surgical ICU. Methods: We applied blood gas adjustment rule, that is aVBG pH = venous blood gas (VBG pH +0.05, aVBG CO2 = VBG pCO2 - 5 mm Hg from the prior studies. In this study, we validated this relationship with simultaneous arterial and central venous blood obtained from 30 patients with four blood sample pairs each in paediatric cardiac surgical ICU patients. Results: There was a strong correlation (R i.e., Pearson's correlation between ABG and aVBG for pH = 0.9544, pCO2 = 0.8738, lactate = 0.9741, HCO3− = 0.9650 and BE = 0.9778. Intraclass correlation co-efficients (ICCs for agreement improved after applying the adjustment rule to venous pH (0.7505 to 0.9454 and pCO2 (0.4354 to 0.741. Bland Altman showed bias (and limits of agreement for pH: 0.008 (−0.04 to + 0.057, pCO2: −3.52 (–9.68 to +2.65, lactate: −0.10 (−0.51 to +0.30, HCO3−: −2.3 (–5.11 to +0.50 and BE: −0.80 (−3.09 to +1.49. Conclusion: ABG and aVBG samples showed strong correlation, acceptable mean differences and improved agreement (high ICC after adjusting the VBG. Hence, it can be promising to use trend values of VBG instead of ABG in conjunction with a correction factor under stable haemodynamic conditions.

    Microorganisms may colonize needleless connectors (NCs) on intravascular catheters, forming biofilms and predisposing patients to catheter-associated infection (CAI). Standard and silver-coated NCs were collected from catheterized intensive care unit patients to characterize biofilm formation using culture-dependent and culture-independent methods and to investigate the associations between NC usage and biofilm characteristics. Viable microorganisms were detected by plate counts from 46% of standard NCs and 59% of silver-coated NCs (P=0.11). There were no significant associations (P>0.05, chi-square test) between catheter type, side of catheter placement, number of catheter lumens, site of catheter placement, or NC placement duration and positive NC findings. There was an association (P=0.04, chi-square test) between infusion type and positive findings for standard NCs. Viable microorganisms exhibiting intracellular esterase activity were detected on >90% of both NC types (P=0.751), suggesting that a large percentage of organisms were not culturable using the conditions provided in this study. Amplification of the 16S rRNA gene from selected NCs provided a substantially larger number of operational taxonomic units per NC than did plate counts (26 to 43 versus 1 to 4 operational taxonomic units/NC, respectively), suggesting that culture-dependent methods may substantially underestimate microbial diversity on NCs. NC bacterial communities were clustered by patient and venous access type and may reflect the composition of the patient's local microbiome but also may contain organisms from the health care environment. NCs provide a portal of entry for a wide diversity of opportunistic pathogens to colonize the catheter lumen, forming a biofilm and increasing the potential for CAI, highlighting the importance of catheter maintenance practices to reduce microbial contamination.

    Full Text Available Ultrasound (US examination of the bladder can precisely determine the bladder volume and is a useful tool in estimating the residual urine volume. Its application is consequently recommended as an alternative to catheterization for the determination of residual urine. Moreover it represents a simple, noninvasive method to predict the outcome of a voiding trial following acute urine retention based on intravesical prostatic protrusion and on the US pattern of the bladder content. In this article, the Authors review the implementation and results of a bladder US program developed for non-medical caregivers at one Emergency Department.

    Objective: The aim of this study was to compare the anatomic-landmark and ultrasound-guided techniques in the placement of an internal jugular vein port in patients with advanced breast cancer. Methods: Between March 2010 and October 2010, 60 patients with advanced breast cancer underwent central venous port placement for the delivery of chemotherapy,preferably through the internal jugular vein. Patients were randomly assigned to either the anatomic-landmark or the ultrasound-guided group. Failure on first attempt, number of attempts until successful catheterization, time to successful placement, the accordance of the two placement approaches, and the demographics of each patient were recorded. Results: The consistency of the direction of two lines drawn using the anatomic-landmark and ultrasound-guided techniques or of the diameter of the internal jugular vein as determined by the two approaches was 85% (51/60). The rate of successful placement at first attempt was higher in the ultrasound group than in the anatomic-landmark group (P < 0.05). A greater number of attempts and longer time to successful port placement were needed in the latter (P < 0.05). Conclusion: The findings of this study indicate that, in the placement of an internal jugular vein port, the ultrasound (US)-guided technique has several advantages over the anatomic-landmark technique.

    Background Central venous pressure (CVP) and intrathoracic blood volume index (ITBVI) were used to assess the fluid status.It has previously been shown that CVP is not as accurate as ITBVI for all the shock patients.We therefore hypothesized that the change of CVP has the ability to predict fluid responsiveness in some clinical cases of shock.Methods From September 1st 2009 to September 1st 2011,sixty-three patients with shock from different Intensive Care Unit (ICU) were collected into this retrospective study.All the patients received fluid challenge strategy (infusing 300 ml hydroxyethyl starch in 20 minutes),were monitored with CVP and pulse-indicated continuous cardiac output (PICCO).The correlation between changes in cardiac index (△CI),CVP (△CVP) and ITBVI (△ITBVI) were analyzed.Fluid responsiveness was defined as an increase in CI≥10%.Receiver operating characteristic (ROC) curves were generated for △CVP and △ITBVI.Results For all the patients,there was no correlation between △CI and △CVP (P=0.073),but in the subgroup analysis,the correlation between △CI and △CVP was significant in those younger than 60 years old (P=-0.018) and those with hypovolemic shock (P=0.001).The difference of areas under the ROC curves of △CVP and △ITBVI were not statistically significant in the group younger than 60 years old or hypovolemic shock group (P >0.05,respectively).However,no similar results can be found in the group older than 60 years old and the other two shock type groups from ROC curves of △CVP and △ITBVI.Conclusions △CVP is not suitable for evaluating the volume status of the shock patients with fluid resuscitation regardless of their condition.However,in some ways,△CVP have the ability to predict fluid responsiveness in the younger shock patients or in the hypovolemic shock patients.

    To compare prospective between insertion of non-cuffed dual lumen catheter in the external jugular vein and other central veins for hemodialysis (HD), we studied 68 chronic dialysis patients randomly allocated into two groups: one with external jugular vein catheterization as access for HD and another with other central venous catheterization, internal jugular or subclavian vein. Our results showed there were no significant differences regarding successful cannulation, com-plications, total numbers of dialysis, development of pain and infection at the site of cannulation, patency rate of the catheters, and efficacy of hemodialysis between both groups. In addition, the patency of the catheter in the external jugular vein was not affected by previous cannulation of other central veins. In contrast, there was a significant correlation between numbers of attempts for cannulation in both groups and development of hematoma and infection, (pvein may be an alternative for other central veins for insertion of temporary non-cuffed hemodialysis catheter.

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

    Full Text Available Background and Aims: The complications of central venous catheterisation can be minimized by ensuring catheter tip placement just above the superior vena cava-right atrium junction. We aimed to compare two methods, using an electrocardiogram (ECG or landmark as guides, for assessing correct depth of central venous catheter (CVC placement. Methods: In a prospective randomised study of sixty patients of <12 years of age, thirty patients each were allotted randomly to two groups (ECG and landmark. After induction, central venous catheterisation was performed by either of the two techniques and position of CVC tip was compared in post-operative chest X-ray with respect to carina. Unpaired t-test was used for quantitative data and Chi-square test was used for qualitative data. Results: In ECG group, positions of CVC tip were above carina in 12, at carina in 9 and below carina in 9 patients. In landmark group, the positions of CVC tips were above carina in 10, at carina in 4 and below carina in 16 patients. Mean distance of CVC tip in ECG group was 0.34 ± 0.23 cm and 0.66 ± 0.35 cm in landmark group (P = 0.0001. Complications occurred in one patient in ECG group and in nine patients in landmark group (P = 0.0056. Conclusion: Overall, landmark-guided technique was comparable with ECG technique. ECG-guided technique was more precise for CVC tip placement closer to carina. The incidence of complications was more in the landmark group.

    Full Text Available Background and Aims: Subclavian central venous catheterisation (CVC is employed in critically ill patients requiring long-term central venous access. There is no gold standard for estimating their depth of insertion. In this study, we compared the landmark topographic method with the formula technique for estimating depth of insertion of right subclavian CVCs. Methods: Two hundred and sixty patients admitted to Intensive Care Unit requiring subclavian CVC were randomly assigned to either topographic method or formula method (130 in each group. Catheter tip position in relation to the carina was measured on a post-procedure chest X-ray. The primary endpoint was the need for catheter repositioning. Mann–Whitney test and Chi-square test was performed for statistical analysis using SPSS for windows version 18.0 (Armonk, NY: IBM Corp. Results: Nearly, half the catheters positioned by both the methods were situated >1 cm below the carina and required repositioning. Conclusion: Both the techniques were not effective in estimating the approximate depth of insertion of right subclavian CVCs.

    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 Objetivo: Determinar los factores que inciden en el tiempo de permanencia de un catéter endovenoso central. Antecedentes: En el paciente con cáncer existen factores propios del estado de inmunocompromiso por el tumor y los efectos colaterales de su tratamiento que aumentan la probabilidad de infección y consecuentemente reducen el tiempo de uso de un catéter. Sujetos: Se integró una cohorte de 306 pacientes con cáncer, con una edad promedio de 59 ± 14,5 años. Intervenciones: Se definió tiempo cero como el día de colocación del catéter. Diariamente se buscaron signos clínicos de infección por catéter, con toma de hemocultivos simultáneos cada 7 días. El desenlace primario fue infección del catéter y el alternativo fin de tratamiento, obstrucción o fallecimiento del paciente. Se comparó el tiempo de permanencia del catéter infectado vs no infectado y su relación con factores de riesgo potenciales. Resultados: Se colocaron 306 catéteres para un total de 4.043 días/catéter. Se infectaron 25 (8,2%. La sobrevida media global fue de 50 días. Se encontró que a mayor tiempo de permanencia, mayor fue la incidencia de infección. En el análisis de sobrevida ajustado, la presencia de infección a distancia (OR = 4,71, IC95% = 1,7-10,1, p = 0,002 fue el factor que mostró una asociación significativa. Conclusiones: El tiempo de vida útil de un catéter es amplia, limitada por la presencia de infección a distancia como factor de riesgo potencial de infección por catéter.Objective: To determine the factors that affect the dwell time of a central venous catheter.

    Background:After cardiac surgery,central venous oxygen saturation (ScvO2) and serum lactate concentration are often used to guide resuscitation;however,neither are completely reliable indicators of global tissue hypoxia.This observational study aimed to establish whether the ratio between the veno-arterial carbon dioxide and the arterial-venous oxygen differences (P(v-a)CO2/C(a-v)O2) could predict whether patients would respond to resuscitation by increasing oxygen delivery (DO2).Methods:We selected 72 patients from a cohort of 290 who had undergone cardiac surgery in our institution between January 2012 and August 2014.The selected patients were managed postoperatively on the Intensive Care Unit,had a normal ScvO2,elevated serum lactate concentration,and responded to resuscitation by increasing DO2 by >10%.As a consequence,48 patients responded with an increase in oxygen consumption (VO2) while VO2 was static or fell in 24.Results:At baseline and before resuscitative intervention in postoperative cardiac surgery patients,a P(v-a)CO2/C(a-v)O2 ratio ≥1.6 mmHg/ml predicted a positive VO2 response to an increase in DO2 of>1 0% with a sensitivity of 68.8% and a specificity of 87.5%.Conclusions:P(v-a)CO2/C(a-v)O2 ratio appears to be a reliable marker of global anaerobic metabolism and predicts response to DO2 challenge.Thus,patients likely to benefit from resuscitation can be identified promptly,the P(v-a)CO2/C(a-v)O2 ratio may,therefore,be a useful resuscitation target.

    Multilumen central venous catheters (CVCs) are not commonly used for power injection. However, in critically ill patients, CVCs - most of which do not have FDA approval for power injection - may be the only available venous access. The pitfalls of multilumen CVCs are illustrated by a case report of a patient in whom extravasation of intravenously administered contrast medium occurred after power injection in a triple-lumen CVC using the lumen with the port furthest from the catheter tip. The underlying mechanisms for the displacement of the initially correctly placed right subclavian CVC could include elevation of both arms of the obese patient or the power injection itself. The distances between port openings and catheter tips of various commercially available multilumen CVCs are assessed. We examine the possible caveats of ECG-guided CVC placement for optimal tip position, discuss technical difficulties related to power injection via CVCs, and review commonly used drugs that may cause extravasation injury. Knowledge of the distances between CVC port openings and the catheter tip are essential for safe intravasal administration of fluids. (orig.)

    In this retrospective study the success and complication rates after radiologically guided port catheter implantation were evaluated. Between 2000 and 2008, 3,160 port catheter systems were implanted in our interventional suite. All interventions were imaging guided. The puncture of the preferably right internal jugular vein (IJV) was ultrasound-assisted and the catheter tip position was controlled with fluoroscopy. Catheter indwelling time and rates of periprocedural, early and late complications were evaluated. 922,599 catheter days (mean, 292 days; range, 0-2,704 days) were documented. The implantation was successful in 3,153 (99.8%) cases. A total of 374 (11.8%; 0.41/1,000 catheter days) adverse events were recorded. Of these, 42 (1.33%) were periprocedural complications. 86 (3.3%; 0.09/1,000 catheter days) early and 246 (9.4%; 0.27/1,000 catheter days) late onset complications occurred after port implantation. The most common complications were blood stream infection (n = 134; 5.1%; 0.15/1,000 catheter days), catheter-induced venous thrombosis (n = 97; 3.7%; 0.11/1,000 catheter days) and catheter migration (n = 34; 1.3%; 0.04/1,000 catheter days). A total of 193 (6.1%) port explantations were required. Ultrasound guided port implantation via the IJV results in low periprocedural complication rates. (orig.)

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

All patients were hemodynamically stable intra- and postoperatively. The intervention was successful in 33 cases and aborted in one case because of severe posteromedial leaflet tethering. The epinephrine and milrinone were weaned and all patients were extubated, except, one case mortality happened within the first 8 hours postoperatively. Percutaneous mitral valve repair with MitraClip implantation is a successful alternative in high-risk patients with symptomatic severe mitral regurgitation. Starting epinephrine before anesthetic induction and milrinone infusion induction resulted in decreased pulmonary artery pressure, increased ejection fraction and maintained arterial blood pressure during procedure inspite of worse preoperative conditions.

    Assessing left ventricular (LV) filling pressure (pulmonary capillary wedge pressure, PCWP) is an important aspect in the care of patients with heart failure (HF). Physicians rely on right ventricular (RV) filling pressures such as central venous pressure (CVP) to predict PCWP, assuming concordance between CVP and PCWP. However, the use of this method is limited because discordance between CVP and PCWP is observed. We hypothesized that PCWP can be reliably predicted by CVP corrected by the relationship between RV and LV function, provided by the ratio of tissue Doppler peak systolic velocity of tricuspid annulus (S(T)) to that of mitral annulus (S(M)) (corrected CVP:CVP·S(T)/S(M)). In 16 anesthetized closed-chest dogs, S T and S M were measured by transthoracic tissue Doppler echocardiography. PCWP was varied over a wide range (1.8-40.0 mmHg) under normal condition and various types of acute and chronic HF. A significantly stronger linear correlation was observed between CVP·S(T)/S(M) and PCWP (R2 = 0.78) than between CVP and PCWP (R2 = 0.22) (P 10.5 mmHg predicted PCWP >18 mmHg with 85% sensitivity and 88% specificity. Area under ROC curve for CVP·S T/S M to predict PCWP >18 mmHg was 0.93, which was significantly larger than that for CVP (0.66) (P < 0.01). Peripheral venous pressure (PVP) corrected by S T/S M (PVP·S(T)/S(M) also predicted PCWP reasonably well, suggesting that PVP·S(T)/S (M) may be a minimally invasive alternative to CVP·S(T)/S(M) In conclusion, our technique is potentially useful for the reliable prediction of PCWP in HF patients.

    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.

    The presence of pneumocephalus without a history of intracranial or intrathecal procedures is a significant radiographic finding. Although pneumocephalus means a violation of the dural barrier or the presence of infection, intravascular pneumocephalus is different from intraparenchymal pneumocephalus and its benign nature must be known in the presence of intravenous catheterization. Herein, we present a case of iatrogenic intravascular pneumocephalus with CT findings. To our knowledge, there are only a few reported cases of iatrogenic intravascular pneumocephalus in the literature. Careful intravenous catheterization and diagnosis of the condition on imaging helps to prevent unnecessary treatment procedures. (orig.)

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

    Full Text Available Background Establishing venous access is a challenging job for pediatric nurses, especially in the emergency department. Measures to ensure higher success rates on the first attempt are important to provide quality nursing care. Objectives To explore the effect of grade management on the success of establishing peripheral venous access in the child population of China and to analyze the factors influencing failed IV access on the first attempt. Methods This is an observational study on children aged 0 - 16 years old undergoing peripheral venous catheterization in a children’s hospital. Patient information was collected before attempting each puncture. Logistic regression was used to identify independent factors for success prediction. Results A total of 1,016 subjects enrolled. The success rate of intravenous puncture on the first attempt was 86.02%. This can be influenced by several factors, such as patient age, department, venous condition, and nurse experience. The success rate within two attempts was 96.85%; the number of catheters used per IV attempt was 1.21. Conclusions To date, only a few studies have explored the success rate of peripheral IV catheterization in the pediatric population of China. Grade management of peripheral veins and pediatric nurses facilitated higher first-attempt success than in previously published reports. Failures of catheterization were multifactorial. The success rate of peripheral intravenous insertion in children can be improved through applying assistance devices or enhancing the venipuncture skills of pediatric nurses.

    Pediatric patients undergoing surgery for spinal deformity may benefit from central venous access to provide intraoperative monitoring and fluid resuscitation. For pediatric surgical patients requiring central access, we hypothesized that placing a peripherally inserted central catheter (PICC) line preoperatively should decrease time from induction of anesthesia to incision and result in improved patient safety and decreased operating room charges. This was a retrospective, nonrandomized, and case comparison study. Clinical records of all children with adolescent idiopathic scoliosis or neuromuscular scoliosis treated surgically by the senior author between December 2007 and April 2012 were reviewed. Control group patients had a central venous catheter (CVC) placed by the anesthesiologist after induction of anesthesia. The trial group had a PICC placed under local anesthesia the day before surgery by an experienced vascular access team. The time from induction of anesthesia to the time for the surgical incision was determined for each study group. The CVC line placement charges were determined by the operating room time charges at $214/min. Charges saved were the mean time difference multiplied by the operating room time charge, less the charge for PICC line insertion ($1282). There were 29 neuromuscular patients, the mean age was 13 years (SD: 4 years). The mean time from induction to incision for the PICC group was 91 min [95% confidence interval (CI): 67-115 min] and for the CVC group 113 min (95% CI: 99-127 min, P=0.083). For this mean time difference of 22 min, the estimated cost savings would be $3426 per patient. There were 59 patients with adolescent idiopathic scoliosis, the mean age was 14 years (SD: 2 years). The mean time from induction to incision for the PICC group was 78 min (95% CI: 74-82 min) and for the CVC group 106 min (95% CI: 96-116  min, P≤0.001). For this mean time difference of 28 min, the estimated cost savings would

    The aim of this study was to predict the probability of central venous catheter-related bloodstream infections (CRBSIs) in patients with haematologic malignancies using a modified version of the Infection Probability Score (mIPS). In order to perform a prospective, mono-centric surveillance of complications in clinical routine due to short-term central venous catheters (CVCs) in consecutive patients receiving chemotherapy from March 2013 to September 2014, IPS was calculated at CVC insertion and removal (mIPSin and mIPSex, respectively). We used the 2012 Infectious Diseases Working Party of the German Society of Haematology and Medical Oncology (AGIHO/DGHO) criteria to define CRBSI. In total, 143 patients (mean 59.5 years, 61.4 % male) with 267 triple-lumen CVCs (4044 CVC days; mean 15.1 days, range 1-60 days) were analysed. CVCs were inserted for therapy of acute leukaemia (53.2 %), multiple myeloma (24.3 %) or lymphoma (11.2 %), and 93.6 % were inserted in the jugular vein. A total of 66 CRBSI cases (24.7 %) were documented (12 definite/13 probable/41 possible). The incidence was 16.3/1000 CVC days (2.9/3.1/10.1 per 1000 CVC days for definite/probable/possible CRBSI, respectively). In CRBSI cases, the mIPSex was higher as compared to cases without CRBSI (13.1 vs. 7.1; p < 0.001). The best mIPSex cutoff for CRBSI prediction was 8 points (area under the curve (AUC) = 0.77; sensitivity = 84.9 %, specificity = 60.7 %, negative predictive value = 92.4 %). For patients with an mIPSex ≥8, the risk for a CRBSI was high (odds ratio [OR] = 5.9; p < 0.001) and even increased if, additionally, CVC had been in use for about 10 days (OR = 9.8; p < 0.001). In case other causes of infection are excluded, a mIPSex ≥8 and duration of CVC use of about 10 days predict a very high risk of CRBSI. Patients with a mIPSex <8 have a low risk of CRBSI of 8 %.

    Full Text Available Abstract Background Although several studies have demonstrated early survival advantages with peritoneal dialysis (PD over hemodialysis (HD, the reason for the excess mortality observed among incident HD patients remains to be established, to our knowledge. This study explores the relationship between mortality and dialysis modality, focusing on the role of HD vascular access type at the time of dialysis initiation. Methods A retrospective cohort study was performed among local adult chronic kidney disease patients who consecutively initiated PD and HD with a tunneled cuffed venous catheter (HD-TCC or a functional arteriovenous fistula (HD-AVF in our institution in the year 2008. A total of 152 patients were included in the final analysis (HD-AVF, n = 59; HD-TCC, n = 51; PD, n = 42. All cause and dialysis access-related morbidity/mortality were evaluated at one year. Univariate and multivariate analysis were used to compare the survival of PD patients with those who initiated HD with an AVF or with a TCC. Results Compared with PD patients, both HD-AVF and HD-TCC patients were more likely to be older (pp = 0.017 and cardiovascular disease (p = 0.020. Overall, HD-TCC patients were more likely to have clinical visits (p = 0.069, emergency room visits (ppvs. 0.93 vs. 0.64, per patient-year; pvs. 0.07 vs. 0.14, per patient-year; p = 0.034 than HD-AVF and PD patients, respectively. The survival rates at one year were 96.6%, 74.5% and 97.6% for HD-AVF, HD-TCC and PD groups, respectively (pp = 0.024.

    Background The lack of medical facilities causes delayed diagnosis and treatment of coronary heart disease in remote mountainous area and/or at disaster site.The miniature mobile cardiac catheterization laboratory was developed to be an intervention platform for coronary heart disease diagnosis and treatment by our team.Pre-clinical research indicated that the miniature mobile cardiac catheterization laboratory performed well in the rescue of critical cardiovascular diseases,even ST-segment elevation myocardial infarction.The present study aimed to evaluate the clinical safety and timeliness of the miniature mobile cardiac catheterization laboratory for emergent coronary interventional diagnosis and treatment.Methods X-ray radiation safety and disinfection efficacy in the miniature mobile cardiac catheterization laboratory were tested during working status.Coronary angiography and/or percutaneous coronary intervention were performed in remote mountainous areas on patients who were first diagnosed as having coronary heart disease by senior interventional cardiologists.The percutaneous coronary intervention procedures and results from patients in the miniature mobile cardiac catheterization laboratory were compared with patients who were treated in the hospital catheter lab.Results The X-ray radiation dosages in the miniature mobile cardiac catheterization laboratory were 39.55 μGy/s,247.4 μGy/h,90.3 μGy/h and 39.4 μGy/h which were corresponded to 0 m,1 m,2 m and 3 m away from the tube central of the medium C-arm.And the radiation dosages used in the miniature mobile cardiac catheterization laboratory were less than the corresponding positions in the hospital catheter lab.The numbers of bacteria colonies in the miniature mobile cardiac catheterization laboratory in different environments range from (60±8) cfu/m3 to (120±10) cfu/m3 and met the demands of percutaneous coronary intervention.A total of 17 patients who received angiography in the miniature mobile

    average duration of in-dwelling catheters was (7.5±2.2)days (range,7 to 21 days).Catheter blockage occurred in 4 neonates 1-3 days after catheterization.The catheter was sheared off and became retracted during demolition but was removed with surgery in 1 neonate.Catheter-related infection occurred with negative blood culture result in 3 neonates (3.75%).No intra-abdominal infection,arrhythmia, necrotic enteritis, liver parenchymal cell inj ury, hepatonecrosis, thrombus, aeroembolism, omphalorrhagia and other complications were found during catheter indwelling.Conclusion Um-bilical venous catheterization is important for intravenous nutritional support in neonates.The technique is relatively easy to grasp and results in fewer adverse reactions.It can be performedearlier and produce higher success rate than the perocutaneous-inserted central venous catheter (PICC).Therefore,umbilical venous catheterization should be widely used for intravenous nutri-tional support,especially in low and extremely low birth weight infants.

    Full Text Available Venous thromboembolism (VTE has been a subject of great interest of late. Since Rudolph Virchow described the famous Virchow′s triad in 1856, there have been rapid strides in the understanding of the pathogenesis and factors responsible for it. Discovery of various thrombophilic factors, both primary and acquired, in the last 40 years has revolutionized prognostication and management of this potentially life-threatening condition due to its associated complication of pulmonary thromboembolism. Detailed genetic mapping and linkage analyses have been underlining the fact that VTE is a multifactorial disorder and a complex one. There are many gene-gene and gene-environment interactions that alter and magnify the clinical picture in this disorder. Point in case is pregnancy, where the risk of VTE is 100-150 times increased in the presence of Factor V Leiden, prothrombin mutation (Prothrombin 20210A and antithrombin deficiency. Risk of VTE associated with long-haul air flight has now been well recognized. Thrombotic events associated with antiphospholipid syndrome (APS are 70% venous and 30% arterial. Deep venous thrombosis and pulmonary embolism are the most common venous events, though unusual cases of catastrophes due to central vein thrombosis like renal vein thrombosis and Budd-Chiari syndrome (catastrophic APS may occur.

    Full Text Available OBJECTIVE: Haematopoietic stem cell recipients need central venous catheters (CVCs for easy administration of intravenous fluid, medications, apheresis, or dialysis procedures. However, CVCs may lead to infectious or non-infectious complications such as thrombosis. The effect of these complications on transplantation outcome is not clear. This manuscript presents the complication rates of double-lumen tunnelled CVCs and their effect on transplantation outcome. METHODS: Data from 111 consecutive patients, of whom 75 received autologous and 36 received allogeneic peripheral blood stem cell transplantations, were collected retrospectively. The data were validated by the Record Inspection Group of the related JACIE-accredited transplantation centre. RESULTS: Thrombosis developed in 2.7% of recipients (0.9 per 1000 catheter days. Catheter-related infection was identified in 14 (12.6% patients (3.6 per 1000 catheter days. Coagulase-negative Staphylococcus was the most common causative agent. Engraftment time, rate of 100-day mortality, and development of grade II-IV graft-versus-host disease were not found to be associated with catheter-related complications. CONCLUSION: Sonuçlarımız nakil hastalarında tünelli SVK komplikasyonlarının yönetilebilir olduğunu ve bu komplikasyonların nakil üzerine olumsuz bir etki yaratmadığını göstermektedir.
