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.

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.)

Role of Catheter-directed Thrombolysis in Management of Iliofemoral Deep Venous Thrombosis.

2016-01-01

The treatment for iliofemoral deep venous thrombosis (DVT) is challenging, as the use of anticoagulation alone can be insufficient for restoring venous patency and thus lead to prolongation of acute symptoms and an increased risk of chronic complications, including venous insufficiency and postthrombotic syndrome (PTS). In these cases, earlier and more complete thrombus removal can ameliorate acute symptoms and reduce long-term sequelae. Endovascular therapies involving the use of pharmacologic, mechanical, and combined pharmacomechanical modalities have been developed to achieve these goals. The most frequently used of these techniques, catheter-directed thrombolysis (CDT), involves the infusion of a thrombolytic agent through a multiple-side-hole catheter placed within the thrombosed vein to achieve high local doses and thereby break down the clot while minimizing systemic thrombolytic agent exposure. Randomized controlled trial results have indicated decreased PTS rates and improved venous patency rates in patients treated with CDT compared with these rates in patients treated with anticoagulation. The use of newer pharmacomechanical techniques, as compared with conventional CDT, reduces procedural times and thrombolytic agent doses and is the subject of ongoing investigations. Endovascular thrombus removal techniques offer a means to improve venous valvular function and decrease the risk of debilitating long-term complications such as PTS and are a promising option for treating patients with iliofemoral DVT.

Central line-associated bloodstream infection (CLABSI, hereafter referred to in this paper as "bloodstream infection") is a leading cause of hospital-acquired infection. To our knowledge, there are no previously published studies designed to determine the rate of bloodstream infection among central venous catheters placed in the emergency department (ED). We design a retrospective chart review methodology to determine bloodstream infection and duration of catheterization for central venous catheters placed in the ED. Using hospital infection control, administrative, and ED billing databases, we identified patients with central venous catheters placed in the ED between January 1, 2007, and December 31, 2008, at one academic, urban ED with an annual census of 57,000. We performed a structured, explicit chart review to determine duration of catheterization and confirm bloodstream infection. We screened 4,251 charts and identified 656 patients with central venous catheters inserted in the ED, 3,622 catheter-days, and 7 bloodstream infections. The rate of bloodstream infection associated with central venous catheters placed in the ED was 1.93 per 1,000 catheter-days (95% confidence interval 0.50 to 3.36). The mean duration of catheterization was 5.5 days (median 4; range 1 to 29 days). Among infected central venous catheters, the mean duration of catheterization was 8.6 days (median 7; range 2 to 19 days). A total of 667 central venous catheters were placed in the internal jugular (392; 59%), subclavian (145; 22%), and femoral (130; 19%) veins. The sensitivity of using ED procedural billing code for identifying ED-placed central venous catheters among patients subsequently admitted to any ICU was 74.9% (95% confidence interval 71.4% to 78.3%). The rate of ED bloodstream infection at our institution is similar to current rates in ICUs. Central venous catheters placed in the ED remain in admitted patients for a substantial period.

The use of central venous catheters for various applications (administration of chemotherapy, blood products and others) in patients with cancer is increasingly frequent. The association between thrombosis and catheter use has been fully established but aspects such as its causes, diagnosis, prophylaxis and treatment have not. We describe a case of thrombosis in a patient with cancer treated with chemotherapy who carried a central venous catheter. We also perform a review of the risk factors, the role of the prophylaxis and the treatment. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.

To assess the impact on the incidence of PPIVC by implementing a catheter management protocol and to determine risk factors for PPIVC development in hospitalized patients. A total of 3978 episodes of venous catheterization were prospectively included from September 2002 to December 2007. A catheter management protocol was implemented during this period of time. The incidence and variables associated to the occurrence of PPIVC were determined. The incidence of PPIVC from 2002 to 2007 was 4.8%, 4.3%, 3.6%, 2.5%, 1.3% and 1.8% (phistory of phlebitis was the only factor independently associated to phlebitis due to peripherally inserted central venous catheters (AOR 3.24; CI at 95% CI= 1.05-9.98, p=0.04). A catheter management protocol decreases the incidence of PPIVC in hospitalized patients. The risk of PPIVC increases for peripherally inserted central venous catheters when the patients have a history of phlebitis and for peripheral venous catheters when amiodarone or cefotaxime are infused. Catheterization of peripheral veins performed during morning shifts is associated with a lower incidence of PPIVC when compared with night shift catheterizations.

Central venous catheterization is widely used in patients on hemodialysis. A rare complication associated with the clinical use of central venous catheters is perforation of the heart or major vessels. We report a case of inadvertent perforation of the left atrium and thrombosis after the placement of a hemodialysis catheter in the right internal jugular vein. In such cases, surgical removal of the central venous catheter from perforation sites in the heart and vessel walls poses anesthetic challenges because of the high risk of pneumothorax, hemorrhage, arrhythmias, thrombosis, and death.

This multi-centre prospective field study evaluated whether peripheral venous catheter site of insertion influences the risk of catheter-related phlebitis. Potential predictors of phlebitis were also investigated. Millions of patients worldwide use peripheral venous catheters, which frequently cause local complications including phlebitis, infection and obstruction. Although phlebitis predictors have been broadly investigated, uncertainties remain on the potential effect of cannulation anatomical site, duration and the appropriate time for catheter removal. A prospective cohort design was carried out from January-June 2012. The clinical course of each patient who received a new peripheral venous catheter for any cause in five Italian hospitals was followed by trained nurses until catheter removal. The presence of phlebitis was assessed every 24 hours using the Visual Infusion Phlebitis score. Analyses were based upon multilevel mixed-effects regression. The final sample consisted of 1498 patients. The average time for catheters in situ was 65·6 hours and 23·6% of the catheters were in place beyond 96 hours. Overall phlebitis incidence was 15·4%, 94·4% of which were grade 1. The likelihood of phlebitis independently increased with increasing catheter duration, being highest after 96 hours. Compared with patients with catheter placed in the dorsum of the hand (22·8% of the sample), those with the catheter located in the antecubital fossa (34·1%) or forearm were less likely to have a phlebitis of any grade. Antecubital fossa and forearm veins may be preferential sites for peripheral venous cannulation. Our results support Centers for Disease Control and Prevention recommendations to replace catheters in adults no later than 96 hours. A relevant proportion of healthcare personnel did not adhere to such guidelines - more attention to this issue is required. © 2014 John Wiley & Sons Ltd.

Catheter-related bloodstream infections (CR-BSIs) are a common, frequently preventable complication of central venous catheterization. CR-BSIs can be prevented by strict attention to insertion and maintenance of central venous catheters and removing unneeded catheters as soon as possible. Antiseptic- or antibiotic-impregnated catheters are also an effective tool to prevent infections. The diagnosis of CR-BSI is made largely based on culture results. CR-BSIs should always be treated with antibiotics, and except in rare circumstances the infected catheter needs to be removed.

Central venous catheter insertion problem solving using intravenous catheter: technical communication

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.

Femoral vein catheterization is an alternative method of obtaining central venous access. Placement of femoral venous catheters (FVCs) is possible in the majority of patients, suitable for most indications, and associated with a low complication rate during insertion. We wished to determine the incidence of infections or other complications resulting when parenteral nutrition was delivered through FVCs. Fifty-two patients were followed from a hospital-wide population including patients in the critical care units. Triple-lumen catheters were placed by using the sterile Seldinger technique, and sites were examined daily for inflammation. Bacteriologic surveillance was accomplished by submitting the catheter tip for semiquantitative cultures. If catheter line sepsis was suspected, blood samples for cultures were drawn through the catheter and peripherally. The rate of occurrence of colonized catheters was 9.6% (five of 52), and catheter sepsis was found in one case (1.9%). Other than inflammation at six (11.5%) of 52 catheter sites, noninfectious complications of FVCs were not found. On the basis of these findings, we consider FVC-delivered parenteral alimentation a safe and effective alternative to other forms of central venous access.

1999-01-01

Purpose: To describe a combined procedure of repositioning and leaving in situ a central venous catheter followed by immediate percutaneous treatment of associated superior vena cava syndrome (SVCS). Methods: Eight patients are presented who have central venous catheter-associated SVCS (n = 6 Hickman catheters, n = 2 Port-a-cath) caused by central vein stenosis (n = 4) or concomitant thrombosis (n = 4). With the use of a vascular snare introduced via the transcubital or transjugular approach, the tip of the central venous catheter could be engaged, and repositioned after deployment of a stent in the innominate or superior vena cava. Results: In all patients it was technically feasible to reposition the central venous catheter and treat the SVCS at the same time. In one patient flipping of the Hickman catheter in its original position provoked dislocation of the released Palmaz stent, which could be positioned in the right common iliac vein. Conclusion: Repositioning of a central venous catheter just before and after stent deployment in SVCS is technically feasible and a better alternative than preprocedural removal of the vascular access

Superior vena cava (SVC) syndrome results from obstruction of flow through the vessel either by external compression or thrombosis. External compression by intrathoracic neoplasms is the most common etiology, especially lung cancer and lymphoma. Thrombosis is becoming increasingly common due to the use of indwelling catheters and implantable central venous access devices. Most patients are unresponsive to anticoagulation alone which appears to be effective only in the mildest cases. However, recent advances in catheter-based interventions have led to the development of a variety of minimally invasive endovascular strategies to remove venous thrombus and accepted as an important first-line treatment given its high overall success rate and low morbidity as compared with medical and surgical treatments. Ultrasound accelerated catheter-directed thrombolysis (UACDT) has been developed to rapidly and completely resolve the existing thrombus. This technique integrates high frequency, low intensity ultrasound (US) with standard CDT in order to accelerate clot dissolution, reducing treatment time and the incidence of thrombolysis-related complications. An US wave enhances drug permeation through thrombus by disaggregating the fibrin matrix, exposing additional plasminogen receptor sites to the thrombolytic agent. The US energy affects thrombus in the entire venous segment, increasing the probability of complete thrombus clearing. We report the case of a 56-year-old man who presented with a 5 days history of SVC syndrome symptoms who had been receiving chemotherapy for colon cancer through a right subclavian vein port catheter. The patient successfully treated with UACDT with EkoSonic(®) Mach4e Endovascular device with an overnight infusion. © 2013 Wiley Periodicals, Inc. Copyright © 2013 Wiley Periodicals, Inc.

Although real-time ultrasound guidance during central venous catheter insertion has become a standard of care, postinsertion chest radiograph remains the gold standard to confirm central venous catheter tip position and rule out associated lung complications like pneumothorax. We hypothesize that a combination of transthoracic echocardiography and lung ultrasound is noninferior to chest radiograph when used to accurately assess central venous catheter positioning and screen for pneumothorax. All operating rooms and surgical and trauma ICUs at the institution. Single-center, prospective noninferiority study. Patients receiving ultrasound-guided subclavian or internal jugular central venous catheters. During ultrasound-guided central venous catheter placement, correct positioning of central venous catheter was accomplished by real-time visualization of the guide wire and positive right atrial swirl sign using the subcostal four-chamber view. After insertion, pneumothorax was ruled out by the presence of lung sliding and seashore sign on M-mode. Data analysis was done for 137 patients. Chest radiograph ruled out pneumothorax in 137 of 137 patients (100%). Lung ultrasound was performed in 123 of 137 patients and successfully screened for pneumothorax in 123 of 123 (100%). Chest radiograph approximated accurate catheter tip position in 136 of 137 patients (99.3%). Adequate subcostal four-chamber views could not be obtained in 13 patients. Accurate positioning of central venous catheter with ultrasound was then confirmed in 121 of 124 patients (97.6%) as described previously. Transthoracic echocardiography and lung ultrasound are noninferior to chest x-ray for screening of pneumothorax and accurate central venous catheter positioning. Thus, the point of care use of ultrasound can reduce central venous catheter insertion to use time, exposure to radiation, and improve patient safety.

There were limited studies on the choices and effects of different types of CVCs for chemotherapy. The aim of this study was to compare the complications, cost, and patients’ quality of life and satisfaction of three commonly used CVCs for chemotherapy, such as implanted venous port, peripherally inserted central catheters (PICCs, and external non-tunneled central venous catheters (NTCs.Methods: A double-center prospective cohort study was carried out from March 2014 to December 2016. Catheterization situation, complications, catheter maintenance, cost, and patients’ quality of life and satisfaction were recorded, investigated, and analyzed. Forty-five ports, 60 PICCs and 40 NTCs were included. All the CVCs were followed up to catheter removal.Results: There was no statistical difference in catheterization success rates between port and PICC. NTC had less success rate by one puncture compared with port. Ports had fewer complications compared with PICCs and NTCs. The complication rates of ports, PICCs and NTCs were 2.2%, 40%, and 27.5%, respectively. If the chemotherapy process was <12 months, NTCs cost least, and the cost of port was much higher than PICC and NTC. When the duration time was longer than 12 months, the cost of port had no difference with the cost of PICC. Quality of life and patients’ satisfaction of port group were significantly higher than the other two groups. Conclusion: Although port catheterization costs more and needs professional medical staff and strict operational

Objective: To study the feasibility, complications, mid- and long-term advantages of peripherally inserted central catheters (PICC) compared with central venous access assisted with X-ray. Methods: From Jan 1997 to Dec 1998, the authors conducted a study in 60 patients with placed PICC lines and 60 patients with central lines. Study variables included tip placement and complication rates. Results: Tere were on significant differences between PICC and CVC in the successful placement 95.0% and 88.3%, t = 1.745, P 0.19; the mean duration 13(6-98) days and 14 (7-104) days, F = 0.049, P = 0.83; the total occlusion rate 6.7% (4/60) and 5.0%(3/60), t = 0.152, P = 0.70. In PICC patients, the occlusion rate was slightly higher in 3 Fr (20-gauge) catheter (3/20, 15.0%) than in 4 Fr(18-gauge) catheters (1/20, 5.0%), t = 1.111, P=0.29. Phlebitis occurred in 5.0% of patients (3/60) and one catheter fracture was happened on the catheter hub junction (1.7%). In 3 catheter tips dislocation cases, the catheter tips were moved to the optional position assisted with X-ray image. In CVC group, pneumothorax happened in 1 case (1.7%). In 4 catheter dislocation cases, the catheters were with drawn. No catheter-related sepsis and hemo-pneumothorax happened in both group patients. Conclusions: Both PICC and CVC can be acceptable in clinical use. PICC assisted with X-ray possesses the advantages of less trauma, accurate localization preventing some possible severe complications of central venous access such as pneumothorax. The new method provides a reliable, effective venous access for mid-and long-term usage in patients receiving a variety of solutions, primarily parenteral alimentation, chemotherapy or antibiotic infusion

The anticoagulant treatment of acute deep venous thrombosis (DVT) has been historically directed toward the prevention of recurrent venous thromboembolism. However, such treatment imperfectly protects against late manifestations of the postthrombotic syndrome. By restoring venous patency and preserving valvular function, early thrombus removal strategies can potentially decrease postthrombotic morbidity. A committee of experts in venous disease was charged by the Society for Vascular Surgery and the American Venous Forum to develop evidence-based practice guidelines for early thrombus removal strategies, including catheter-directed pharmacologic thrombolysis, pharmacomechanical thrombolysis, and surgical thrombectomy. Evidence-based recommendations are based on a systematic review and meta-analysis of the relevant literature, supplemented when necessary by less rigorous data. Recommendations are made according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, incorporating the strength of the recommendation (strong: 1; weak: 2) and an evaluation of the level of the evidence (A to C). On the basis of the best evidence currently available, we recommend against routine use of the term "proximal venous thrombosis" in favor of more precise characterization of thrombi as involving the iliofemoral or femoropopliteal venous segments (Grade 1A). We further suggest the use of early thrombus removal strategies in ambulatory patients with good functional capacity and a first episode of iliofemoral DVT of venous outflow obstruction (Grade 1A). We suggest pharmacomechanical strategies over catheter-directed pharmacologic thrombolysis alone if resources are available and that surgical thrombectomy be considered if thrombolytic therapy is contraindicated (Grade 2C). Most data regarding early thrombus removal strategies are of low quality but do suggest patient-important benefits with respect to reducing postthrombotic morbidity. We

Central venous catheters are frequently used as access for hemodialysis (HD) in children. One of the known complications is central venous stenosis. Although this complication is not rare, it is often asymptomatic and therefore unacknowledged. Superior vena cava (SVC) stenosis is obviously suspected in the presence of upper body edema, but several other signs and symptoms are often unrecognized as being part of this syndrome. We describe four patients with various manifestations of central venous stenosis and SVC syndrome. These sometimes life- or organ-threatening conditions include obstructive sleep apnea, unresolving stridor, increased intracranial pressure, increased intraocular pressure, right-sided pleural effusion, protein-losing enteropathy and lymphadenopathy. The temporal relationship of these complications associated with the use of central venous catheters and documentation of venous stenosis, together with their resolution after alleviation of high venous pressure, points to a causal role. We suggest pathophysiological mechanisms for the formation of each of these complications. In patients with occlusion of the SVC, various unexpected clinical entities can be caused by high central venous pressure. As often the etiology is not obvious, a high index of suspicion is needed as in some cases prompt alleviation of the high pressure is mandatory.

Full Text Available Recent advances in anticancer chemotherapy have resulted in an increase in the number of patients requiring a central venous port catheter, and the incidence of catheter pinch-off syndrome has been increasing. Catheter pinch-off syndrome is a rare and unusual complication. It is difficult to retrieve dislodged catheters from the pulmonary artery, especially if the catheter is stuck to the peripheral pulmonary artery. We herein describe the successful removal of a catheter stuck in the pulmonary artery with a stepwise approach. First, a pigtail catheter was used to tug the dislodged catheter in order to free the unilateral end. Then, a gooseneck snare was used to catch and pull the catheter out of the patient. The key to success is to free the end of the catheter.

To discover the incidence of central venous catheters (tunnelled, subcutaneous and PICC) in patients with onco-hematological conditions, hospitalized in the Hematology or Transplantations of Hematopoietic Stem Cells Units, in two tertiary care hospitals. A cross-sectional, descriptive study form was developed in order to gather sociodemographic, clinical data as well as complications and follow-up of the care protocol. Each catheter was assigned a correlative identification number. Information was collected on 366 catheters: 185 in the University Hospital Ramón y Cajal (HURYC), 80 tunnelled, 40 subcutaneous venous access and 65 PICC, and 181 in the University Hospital Gregorio Marañón (HUGM), 101 tunnelled and 80 subcutaneous venous access. Major complications in the tunnellized were infections (13.7% in HURYC vs. 6.8% in HUGM - p<0.001) and occlusions (at least once in 3.8% vs. 21.8%). In subcutaneous venous access, infections were confirmed in 5% in HURYC vs. 1.2% in HUGM. There were occlusions at least once in 10% in HUGM and no other significant complications were detected. Regarding PICC, information was only collected in HURYC, where complications were phlebitis 10.8%, thrombosis 7.7%, confirmed or suspected infection 4.6%, occlusion at least once 7.7%. Differences between hospitals with regard to major complications, infection and occlusion may be related to different care protocol. We need to stress the high incidence of phlebitis and thrombosis in PICC catheters, compared with data of lower incidence of other papers. Copyright © 2015 Elsevier España, S.L.U.

Parenteral nutrition for neonates may be delivered via a short peripheral cannula or a central venous catheter. The latter may either be inserted via the umbilicus or percutaneously. Because of the complications associated with umbilical venous catheter use, many neonatal units prefer to use percutaneously inserted catheters following the initial stabilisation period. The method of parenteral nutrition delivery may affect nutrient input and consequently growth and development. Although potentially more difficult to place, percutaneous central venous catheters may be more stable than peripheral cannulae, and need less frequent replacement. These delivery methods may also be associated with different risks of adverse events, including acquired systemic infection and extravasation injury. To determine the effect of infusion via a percutaneous central venous catheter versus a peripheral cannula on nutrient input, growth and development, and complications including systemic infection, or extravasation injuries in newborn infants who require parenteral nutrition. The standard search strategy of the Cochrane Neonatal Review Group was used. This included searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2007), MEDLINE (1966 - February 2007), EMBASE (1980 - February 2007), conference proceedings, and previous reviews. Randomised controlled trials that compared the effect of delivering parenteral nutrition via a percutaneous central venous catheter versus a peripheral cannulae in neonates. Data were extracted the data using the standard methods of the Cochrane Neonatal Review Group, with separate evaluation of trial quality and data extraction by each author, and synthesis of data using relative risk, risk difference and mean difference. Four trials eligible for inclusion were found. These trials recruited a total of 368 infants and reported a number of different outcomes. One study showed that the use of a percutaneous

Catheter thrombosis is common and results in inadequate dialysis treatment and, frequently, in catheter loss. Since dialysis treatment runs on a strict schedule, occluded catheters need to be restored in a timely and cost effective manner. We present a new shortened protocol of urokinase infusion that allows hemodialysis to be performed within 90 minutes. To chronic hemodialysis patients, who developed complete catheter occlusion, urokinase was infused simultaneously through both lumens of the catheter (125,000 units to each lumen) over 90 minutes. Technical success was defined as restoring blood pump speed to at least 250 ml/min. We determined the average time from catheter placement to first clot event (primary patency PP), recurrent clot event after urokinase treatment (secondary patency SP), catheter salvage rate and cause for removal. 37 catheters developed total thrombosis and urokinase was used to restore patency one or more times (total 47 treatments). Catheter salvage rate was 97 %. The average time of PP was 152 ± 56 days (7 - 784 days). Nine patients (30%) developed recurrent occlusion and the average time of SP was 64 ± 34 days (2 - 364 days). One catheter was removed because of dysfunction due to thrombosis. Other catheters were removed due to infection, fistula maturation or fell out spontaneously. Hemodialysis was performed immediately after treatment with blood speed of 250 ml/min in all patients. Our protocol is highly effective, short, and allows to restore patency of totally occluded central venous catheters with minimal disruption of the dialysis session.

It has been reported that early clot removal benefits patients with iliofemoral deep venous thrombosis (DVT) by removing obstruction and preserving valve function. However, a substantial number of patients who had successful clot removal develop post-thrombotic syndrome (PTS). Residual thrombus and rethrombosis play a part in this phenomenon, but the role of coexisting primary chronic venous disease (PCVD) in these patients has not been studied. All patients who underwent catheter-based techniques of thrombus removal for symptomatic acute iliofemoral DVT during a 5-year period compose the study group. These patients were assessed for PTS by the Villalta scale, the Venous Clinical Severity Score (VCSS), and the Venous Insufficiency Epidemiological and Economic Study on Quality of Life (VEINES-QOL) questionnaire. The presence of coexisting PCVD was determined by clinical and duplex ultrasound findings in the contralateral leg at the time of the initial DVT diagnosis. Patients who had coexisting PCVD were compared with those without PCVD. Forty patients (40 limbs) were included in the study group. At initial diagnosis, 15 patients (38%) had coexisting symptomatic primary valve reflux in the unaffected limb. After thrombolysis, 9 of 40 limbs (22%) had complete lysis, 29 (73%) had ≥ 50% to 99% lysis, and 2 (5%) had thrombus removal techniques. Copyright © 2015 Society for Vascular Surgery.

The objective of this study was to prospectively determine the incidence of venous thrombosis (VT) in the upper limbs in patients with peripherally inserted central catheters (PICC). We prospectively investigated the incidence of VT in the upper limbs of 26 patients who had PICC inserted. The inclusion criteria were all patients who had a PICC inserted, whilst the exclusion criterion was the inability to perform a venogram (allergies, previous contrast medium reaction and inability of gaining venous access). Both valved and non-valved catheters were evaluated. Prior to removal of the PICC, an upper limb venogram was performed. The number of segments involved with VT were determined. The duration of central venous catheterization was classified as; less than 6 days, between 6 days and 14 days and more than 14 days. VT was confirmed in 38.5% (10/26) of the patients. The majority 85.7% (12/14) were complete occlusive thrombi and the majority of VT only involved one segment. There was no statistical correlation between the site of insertion of the PICC and the location of VT. Neither was there any observed correlation between the occurrence of VT with the patient's history of hypertension, hypercholesterolaemia, coronary artery disease, diabetes mellitus, cardiac insufficiency, smoking or cancer. There was also no statistical correlation with the size of the catheter. In conclusion, PICCs are associated with a significant risk of upper extremity deep vein thrombosis (UEVT).

ABSTRACT Objective: to determine the incidence rate and risk factors for the nursing-sensitive indicators phlebitis and infiltration in patients with peripheral venous catheters (PVCs). Method: cohort study with 110 patients. Scales were used to assess and document phlebitis and infiltration. Socio-demographic variables, clinical variables related to the PVC, medication and hospitalization variables were collected. Descriptive and inferential analysis and multivariate logistic models were used. Results: the incidence rate of phlebitis and infiltration was respectively 43.2 and 59.7 per 1000 catheter-days. Most PVCs with these vascular traumas were removed in the first 24 hours. Risk factors for phlebitis were: length of hospital stay (p=0.042) and number of catheters inserted (p<0.001); risk factors for infiltration were: piperacillin/tazobactan (p=0.024) and the number of catheters inserted (p<0.001). Conclusion: the investigation documented the incidence of nursing-sensitive indicators (phlebitis and infiltration) and revealed new risk factors related to infiltration. It also allowed a reflection on the nursing care necessary to prevent these vascular traumas and on the indications and contraindications of the PVC, supporting the implementation of the PICC as an alternative to PVC.

Tan, E C; van der Vliet, J A

1999-09-11

Laborious attempts at introducing a central venous catheter for parenteral nutrition in two women, aged 36 and 62 years, were followed by shortness of breath after 32 and 10 hours, respectively. This symptom was due to a (tension) pneumothorax not visible on earlier roentgenograms. Thoracic drainage led to recovery. In all patients with a central venous catheter an undetected delayed pneumothorax can be present. Urgent chest X-ray examination should be performed in all patients with acute respiratory symptoms. Patients undergoing elective intubation with positive pressure breathing should be examined carefully, since they are at risk of developing a late (tension) pneumothorax.

The simulation study was conducted for the new venous catheter with side holes of contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) to evaluate the infusion pressure on four contrast media and several injection speeds. All infusion pressure of the new venous catheter with side holes were less than 15 kg/cm 2 as limitation of extension tube and also reduced the infusion pressure by 15% at the maximum compared to the catheter with single hole. The results suggest that the new venous catheter with side holes can reduce the infusion pressure by power injection of contrast-enhanced CT and MRI.

Full Text Available Umbilical venous catheterization is a necessity for the advanced care of very low birth weight neonates. Even with utmost care, few complications cannot be avoided. Fractured and retained catheter fragments are one of them. Endoluminal retrieval of such a catheter is an uncommon and challenging procedure for the interventionist. The only alternative is an open exploration of these patients. Various techniques have been described for retrieval of such foreign bodies. We describe a novel technique for percutaneous retrieval of an embolized umbilical venous catheter from a very low birth weight neonate.

Permanent venous catheters have emerged as a long-term vascular access option for renal replacement therapy in end-stage renal disease patients. The design and venous location of catheter devices bear intrinsic flow limitations that may negatively affect the adequacy of dialysis and the patient outcome. There is limited data comparing the long-term dialysis adequacy delivered with permanent catheters vs arterio-venous vascular accesses (AVA). To explore this problem, we conducted a prospective 24-month trial comparing the flow performances and dialysis dose (Kt/Vdp) deliveries of both access options in a group of 42 haemodialysis patients during two study phases. During the first 12 months the patients completed a treatment period by means of permanent dual silicone catheters (DualKT). Then they were transferred to an AVA (40 native arterio-venous fistulas and two PTFE grafts) and monitored for an additional 12-month period. Assessments of flow adequacy and dialysis quantification were performed monthly. Dialysis adequacy was achieved in all cases. No patient had to be transferred prematurely to the AVA because of catheter failure. Three catheters had to be replaced due to bacteraemia in three patients. The mean effective blood flow rates achieved were 316+/-3.5 ml/min and 340+/-3.3 ml/min with DualKT and AVA, respectively, for a pre-set machine blood flow of 348+/-2.2 ml/min. Recirculation rates evaluated with the 'slow blood flow' method were 8.6+/-0.6 and 12.1+/-0.8% for DualKT and AVA using mean values of the solute markers urea and creatinine. Due to the possibility of a comparison veno-venous vs arterio-venous blood circulation, a corrected arterio-venous access recirculation could be derived from the difference between the two, which was around 3%. The blood flow resistance of the DualKT was slightly higher than with AVA as indicated by venous pressure differences. Kt/Vdp delivered was 1.37+/-0.02 and 1.45+/-0.02 with DualKT and AVA access respectively. The

Multiple lumen umbilical venous catheters (ML-UVCs) instead of single lumen UVCs (SL-UVCs) may decrease the need for additional venous lines. Although it seems self-evident that ML-UVCs would reduce the need of additional venous lines, the rates of associated complications might be different. To compare the effectiveness and the safety of ML-UVCs versus SL-UVCs in terms of need of additional vascular access, rates of complications, morbidity and mortality in newborn infants. Randomized and quasi-randomized trials were identified by searching the MEDLINE (1966 - February 2005), EMBASE (1980- February 2005), CINAHL (1982 - February 2005), the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 4, 2004) and Science Direct (subject area: medicine, journal and abstract database; 1967 to February 2005). Literature search also included a manual search of the abstracts of scientific meetings published in Pediatric Research (1990-2004). Additional citations were sought using references in articles retrieved from searches. Subject experts were contacted to identify the unpublished and ongoing studies. Randomized and quasi-randomized controlled clinical trials comparing safety and efficacy of multiple versus single lumen umbilical venous catheter in neonates (both term and preterm) who were in need of umbilical venous catheter insertion for vascular access in first four weeks of life. Each review author performed data extraction independently and differences were resolved by discussion. The following outcomes were determined: total number of additional peripheral intravenous lines per baby in first week and first four weeks of life, total number of additional percutaneously and surgically placed central venous lines per baby in first four weeks of life, and other safety and efficacy measures. The treatment effect estimators used were RR, RD, and WMD when appropriate along with their 95% CI. If RD was statistically significant, then number

Chest X-ray is routinely performed to check the position of the central venous catheter (CVC) inserted through the internal jugular or subclavian vein, while the further evaluation of CVC malfunction is usually performed by contrast venography. In patients with superior vena cava obstruction, the tip of the catheter is often seen in collateral mediastinal venous pathways, rather than in the superior vena cava. In such cases detailed knowledge of thoracic vessel anatomy is necessary to identify the exact location of the catheter. We report a case of 32-year-old female patient with relapsing mediastinal lymphoma and previous superior vena cava obstruction with collateral azygos-hemiazygos venous pathways. The patient had CVC inserted through the left subclavian vein and its position was detected by CT to be in the dilated left superior intercostal vein and accessory hemiazygos vein. Considering that dilated accessory hemiazygos vein can tolerate infusion, the CVC was left in place and the patient had no complaints related to CVC (mal)position. Furthermore, we present anatomical and radiological observations on the azygos-hemiazygos venous system with the special emphasis on the left superior intercostal vein. Non-contrast CT scans can be a valuable imaging tool in the detection of the CVC position, especially in patients with renal insufficiency and contrast media hypersensitivity

When one port does not return blood: two case reports of rare causes for misplaced central venous catheters

Full Text Available We present two cases of misplaced central venous catheters having in common the absence of free blood return from one lumen immediately after placement. The former is a case of right hydrothorax associated with central venous catheterization with the catheter tip in intra-pleural location. In this case the distal port was never patent. In the latter case there was an increased aspiration pressure through the middle port due to a catheter looping.The absence of free flow on aspiration from one lumen of a central catheter should not be undervalued. In these circumstances the catheter should not be used and needs to be removed. Resumo: Apresentamos dois casos de mau posicionamento de cateter venoso central. Têm em comum a ausência do retorno sanguíneo livre em um dos lúmens imediatamente após a colocação. O primeiro é um caso de hidrotórax direito associado ao cateterismo venoso central, com a ponta do cateter em localização intrapleural. Nesse caso, a porta distal nunca esteve patente. No segundo caso houve um aumento da pressão de aspiração através da porta medial por causa da formação de alça no cateter.A ausência de fluxo livre na aspiração de um lúmen do cateter central não deve ser subestimada. Nessas circunstâncias, o cateter não deve ser usado e deve ser removido.

Central venous catheter (CVC) and hemodialysis (HD) catheter usage are associated with complications that occur during catheter insertion, dwell period, and removal. This study aims to identify and describe the incidence rates of catheter-related complications in a large patient population in a United States-based health care claims database after CVC or HD catheter placement. Patients in the i3 InVision DataMart® health care claims database with at least 1 CVC or HD catheter insertion claim were categorized into CVC or HD cohorts using diagnostic and procedural codes from the US Renal Data System, American College of Surgeons, and American Medical Association's Physician Performance Measures. Catheter-related complications were identified using published diagnostic and procedural codes. Incidence rates (IRs)/1000 catheter-days were calculated for complications including catheter-related bloodstream infections (CRBSIs), thrombosis, embolism, intracranial hemorrhage (ICH), major bleeding (MB), and mechanical catheter-related complications (MCRCs). Thirty percent of the CVC cohort and 54% of the HD cohort had catheter placements lasting <90 days. Catheter-related complications occurred most often during the first 90 days of catheter placement. IRs were highest for CRBSIs in both cohorts (4.0 [95% CI, 3.7-4.3] and 5.1 [95% CI, 4.7-5.6], respectively). Other IRs in CVC and HD cohorts, respectively, were thrombosis, 1.3 and 0.8; MCRCs, 0.6 and 0.7; embolism, 0.4 and 0.5; MB, 0.1 and 0.3; and ICH, 0.1 in both cohorts. Patients with cancer at baseline had significantly higher IRs for CRBSIs and thrombosis than non-cancer patients. CVC or HD catheter-related complications were most frequently seen in patients 16 years or younger. The risk of catheter-related complications is highest during the first 90 days of catheter placement in patients with CVCs and HD catheters and in younger patients (≤16 years of age) with HD catheters.

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.

To evaluate the efficacy and safety of radiologic venous port placement in children under venous anesthesia. Between April 2009 and July 2011, 44 ports were implanted in 41 children (24 boys, 17 girls). The age of patients ranged from 9 months to 19 years (mean, 6.5 years) and their body weights ranged from 6.8 kg to 56.3 kg (mean, 23.2 kg). Right internal jugular vein access was used in 42 ports, right subclavian vein in 1, and left subclavian in 1. Durability and complications of port implantation were reviewed. The technical success rate was 100%. The catheter life was 10-661 days (mean 246 days). Two patients died during the follow-up period, 21 and 6 ports were removed at the end of treatment or as a result of complications, respectively. One port was removed and replaced by a Hickmann catheter. Three ports were explanted due to port-related sepsis, one due to a catheter kink, and two for unexplained fever or insertion site pain. The overall port-related infection was 3 cases (6.8%, 0.28/1000 catheter days). Venous port placement by interventional radiologists in children under intravenous sedation is relatively safe, with a high rate of technical success and low rate of complications.

To determine the incidence of catheter-related infection in patients with pulmonary arterial hypertension (PAH) receiving epoprostenol (EPO), and to note an etiologic role for Micrococcus spp, which is rarely reported as a pathogen in the medical literature. Observational study. Two PAH specialty treatment centers, Harbor-UCLA Medical Center (Torrance, CA), and the College of Physicians and Surgeons, Columbia University (New York, NY). A total of 192 patients with PAH receiving continuous therapy with IV EPO. From 1987 to 2000, 192 patients with PAH received infusions of EPO via central venous catheter. Catheter care included regular dressing changes with dry gauze using a sterile procedure, without the use of flushes. Patients were asked to report on known infections and treatments, and symptoms. All infections were verified by a telephone call to the patient, care provider, and microbiology laboratory whenever possible. There were 335,285 catheter days (mean +/- SD, 1,325 +/- 974 catheter days). There were 88 clinical catheter infections with 51 blood culture-positive infections, necessitating catheter removal in 38 instances. The following pathogens were isolated: Staphylococcus aureus (25); Micrococcus spp (14); mixed flora (3); coagulase-negative Staphylococcus spp (2); Corynebacterium spp (2); Serratia marcessens (1); Enterobacter spp (1); Pseudomonas aeruginosa (1); enterococci (1); and unidentified Gram-positive cocci (1). The catheter infection rate was 0.26 per 1,000 catheter days. The use of long-term therapy with continuous EPO appears to be associated with a low incidence of catheter-related infections. Micrococcus spp were the second most common etiologic agent. Caregivers managing patients with PAH must be aware of the risk of catheter infection, as it may contribute to the morbidity and mortality associated with the use of EPO. When isolated, Micrococcus spp should not be viewed as a contaminant, but rather as a true pathogen that may require

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)

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 Aims: To evaluate the accuracy of measurement of hepatic venous pressure gradient by catheter wedge as compared to balloon wedge (the gold standard. Materials and Methods: Forty-five patients having a clinical diagnosis of intrahepatic portal hypertension were subjected to the two different types of pressure measurements (catheter wedge and balloon wedge during transjugular liver biopsy under fluoroscopic guidance. Statistical Analysis: Spearman′s rank correlation coefficient, Bland-Altman plot for agreement, and single measure intraclass correlation were used for analysis of data. Results: There was a close correlation between the results obtained by both the techniques, with highly significant concordance (P < 0.0001. Hepatic venous pressure gradients as measured by the catheter wedge technique were either equal to or less than those obtained by the balloon wedge technique. Conclusions: The difference in hepatic venous pressure gradients measured by the two techniques is insignificant.

Purpose. To compare the differences in practice and outcome of all radiologically and surgically placed central venous catheters retrospectively over a 2-year period simultaneously, at a single institution. Methods.A total of 253 Hickman catheters were inserted in 209 patients; 120 were placed radiologically in 102 patients and 133 were placed surgically in 107 patients. The indication was chemotherapy in 76% of radiological and in 47% of surgical cases; the remainder were for total parenteral nutrition and venous access. Results. There were 6 (4.5%) primary surgical failures and a further 17 (13%) surgical cases requiring multiple placement attempts. Pneumothorax occurred once (0.8%) surgically and four times (3.3%) radiologically. There were no radiological primary misplacements but there were five (3.7%) surgical ones. Catheter or central vein thrombosis occurred in four (3.3%) radiological and five (3.7%) surgical cases. The rate of infection per 1000 catheter-days was 1.9 in radiologically placed catheters and 4.0 in surgically placed ones (p<0.001). Average catheter life-span was similar for the two placement methods (100±23 days). Conclusion. Radiological placement is consistently more reliable than surgical placement. There are fewer placement complications and fewer catheter infections overall

To evaluate the efficacy of catheter-directed thrombolysis in treating symptomatic deep venous thrombosis (DVT) in lower limbs. Twenty-six consecutive patients (16 male and 10 female; mean age, 55 years) with lower extremity DVT underwent thrombolytic therapy. The duration of symptoms was 1-90 (mean, 17) days: 20 days or less in 16 cases (acute DVT) and less than 20 days in ten (chronic DVT). Catheter-directed infusions of urokinase were administered via ipsilateral popliteal veins, and angioplasty or stent placement was performed after the thrombolytic procedure. Oral medication of warfarin continued for six months, and for the evaluation of venous patency, follow-up ultrasonography was performed. The total dose of infused urokinase was 1,750,000-10,000,000 (mean 4,84,000) IU, and the total procedural time was 25-115 (mean, 64) hours. Lysis was complete in 16 cases (62%, all acute DVT), partial in five (19%, chronic DVT), and failed in five (19%, chronic DVT). Eight patients with venous stenosis and two with occlusion were treated by means of angioplasty (n=3D4) or Wallstent placement (n=3D6). Minor bleeding occurred in six cases and major complications in two (one of pulmonary embolism, and one of multiorgan failure). Catheter-directed thrombolysis with urokinase is effective for the treatment of DVT in lower limbs. (author)

Full Text Available BACKGROUND Temporary and permanent central venous catheters are used in majority of patients of CKD when initiated on hemodialysis and mostly these catheters act as bridge before permanent AV fistula assess could be obtained. Blood stream infections related to these central venous catheters are an important cause of morbidity and mortality in these patients. Appropriate antiseptic precautions while inserting central venous catheter and early identification of catheter related blood stream infections (CRBSI are of utmost importance for reducing hospital stay, cost of therapy and mortality. MATERIALS AND METHODS A total of 50 patients of CKD were included in the study who had central venous catheter in situ (internal jugular or subclavian and developed symptoms related to blood stream infections. Blood cultures were obtained from the catheter lumen and a separate venous site 1 hour apart. All the culture sensitivity reports were obtained from department of microbiology of our institute. Inclusion Criteria- Known case of CKD patients aged more than 18yrs on hemodialysis with symptoms and signs of catheter related blood stream infections were included in the study. Exclusion Criteria- Patients with other associated comorbid infections like Koch’s, urinary tract infection or others mimicking symptoms of CRBSI. RESULTS The cultures were found positive in 38 patients (76% while in rest 24% cases positive cultures could not be obtained. Out of culture positive patients 52.63% cases were found to have gram positive infections while 44.74% had gram negative infections. In 2.63% patients, fungus was isolated to be the causative organism. Among the gram positive organisms 50% had CoNS, 30% had MSSA and 20% had MRSA infections. Among the gram negative group, 47.06% had klebsiella, 23.53% had acinetobacter, 17.65% had E.coli and 11.76% had pseudomonas as the causative organisms. Mortality was observed in 14% patients out of which 28.57% were culture

Spontaneous migration of central venous catheter tip following extubation

2014-01-01

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.

Peripherally inserted central catheters (PICCs) are considered a safe method to provide long-term antibiotic therapy, chemotherapy and nutrition support. Deep venous thrombosis (DVT) is a complication that requires early PICC removal, may extend hospitalization and can result in pulmonary embolism. PICC insertion teams strive to understand risk factors and develop methods to prevent DVTs. However, they can only manage what they can measure. At LDS Hospital, identification of PICC associated DVTs was dependent on verbal notification or manual surveillance of more than a thousand free-text vascular reports. Accurate DVT rates were not known which hindered prevention. We describe the development of a computer application (PICC-DVT monitor) to identify PICC associated DVTs each day. A one-year evaluation of the monitor by the PICC team and a review of 445 random vascular reports found a positive predictive value of 98%, sensitivity of 94%, specificity of 100% and a PICC team associated DVT rate of 2.8%.

Full Text Available Septic thrombophlebitis of a vein is a rare but life-threatening complication of an intravascular (IV catheter placed percutaneously in the veins. Most published clinical experiences with IV catheters, mainly in the outpatient settings, have reported very low rates of catheter-related bloodstream infection compared to rates with central venous catheters placed in a subclavian or internal jugular vein. Most of the complications reported with IV catheters have been non-infectious, particularly sterile phlebitis or thrombosis. We report a case of cephalic vein suppurative thrombophlebitis from an intravascular catheter and offer guidelines for diagnosis and management of this complication.

Venous catheter-related infections are a problem of particular importance, due to their frequency, morbidity and mortality, and because they are potentially preventable clinical processes. At present, the majority of hospitalized patients and a considerable number of outpatients are carriers of these devices. There has been a remarkable growth of knowledge of the epidemiology of these infections, the most appropriate methodology for diagnosis, the therapeutic and, in particular, the preventive strategies. Multimodal strategies, including educational programs directed at staff and a bundle of simple measures for implementation, applied to high-risk patients have demonstrated great effectiveness for their prevention. In this review the epidemiology, the diagnosis, and the therapeutic and preventive aspects of these infections are updated. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Full Text Available Objectives: To evaluate the accuracy of the simultaneous analysis of three radiographic anatomical landmarks – diaphragm, cardiac silhouette, and vertebral bodies – in determining the position of the umbilical venous catheter distal end using echocardiography as a reference standard. Methods: This was a cross-sectional, observational study, with the prospective inclusion of data from all neonates born in a public reference hospital, between April 2012 and September 2013, submitted to umbilical venous catheter insertion as part of their medical care. The position of the catheter distal end, determined by the simultaneous analysis of three radiographic anatomical landmarks, was compared with the anatomical position obtained by echocardiography; sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated. Results: Of the 162 newborns assessed by echocardiography, only 44 (27.16% had the catheter in optimal position, in the thoracic portion of the inferior vena cava or at the junction of the inferior vena cava with the right atrium. The catheters were located in the left atrium and interatrial septum in 54 (33.33% newborns, in the right atrium in 26 (16.05%, intra-hepatic in 37 (22.84%, and intra-aortic in-one newborn (0.62%. The sensitivity, specificity and accuracy of the radiography to detect the catheter in the target area were 56%, 71%, and 67.28%, respectively. Conclusion: Anteroposterior radiography of the chest alone is not able to safely define the umbilical venous catheter position. Echocardiography allows direct visualization of the catheter tip in relation to vascular structures and, whenever possible, should be considered to identify the location of the umbilical venous catheter.

Colonization of a Central Venous Catheter by the Hyaline Fungus Fusarium solani Species Complex: A Case Report and SEM Imaging

Directory of Open Access Journals (Sweden)

Alberto Colombo

2013-01-01

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

To describe the incidence and risk factors of venous thromboembolism in a large sample of critical care pediatric, adolescent, and young adult trauma patients. The National Trauma Data Bank-the largest and most complete aggregation of trauma registry data in the United States. Seven hundred eighty-four level I to level IV trauma centers. Patients ≤ 21 yrs of age who spent at least 1 day in a critical care unit during a trauma admission between 2001 and 2005. To characterize differences between patients with and without venous thromboembolism, we extracted variables regarding patient demographics, injury pattern and severity, procedures, total length of stay, and intensive care unit and ventilator days. Odds ratios for predictors of venous thromboembolism were estimated with a logistic regression model. Among the 135,032 critical care patients analyzed, venous thromboembolism was uncommon (6 per 1,000 discharges). Placement of a central venous catheter was a significant predictor of venous thromboembolism (odds ratio = 2.24; p central venous catheter were of even greater magnitude, particularly in adolescents and young adults. The risk of venous thromboembolism in critical care patients without a central venous catheter was central venous access.

2007-01-01

The aim of this retrospective study was to analyse the outcomes of central venous catheter (CVC) placement carried out by an interventional radiology unit. A review of our hospital records identified 331 consecutive patients who underwent insertion of a tunnelled or non-tunnelled CVC between January 2000 and December 2004. Key outcome measures included the technical success rate of CVC insertion and the percentage of immediate ( 30 days) complications. A total of 462 CVCs were placed under radiological guidance, with an overall success rate of 98.9%. Immediate complications included one pneumothorax, which was diagnosed 7 days after subclavian CVC insertion, and eight episodes of significant haematoma or bleeding within 24 h of CVC insertion. No cases were complicated by arterial puncture or air embolus. Catheter-related sepsis occurred in 2% of non-tunnelled CVC and 8.9% of tunnelled CVC. The overall incidence of catheter-related sepsis was 0.17 per 100 catheter days. As the demand for chemotherapy and haemodialysis grows with our ageing population, interventional radiology suites are well placed to provide a safe and reliable service for the placement of central venous access devices

Improving patient safety during insertion of peripheral venous catheters: an observational intervention study

Kampf, Günter

2013-11-01

Full Text Available [english] Background: Peripheral venous catheters are frequently used in hospitalized patients but increase the risk of nosocomial bloodstream infection. Evidence-based guidelines describe specific steps that are known to reduce infection risk. However, the degree of guideline implementation in clinical practice is not known. The aim of this study was to determine the use of specific steps for insertion of peripheral venous catheters in clinical practice and to implement a multimodal intervention aimed at improving both compliance and the optimum order of the steps.Methods: The study was conducted at University Hospital Hamburg. An optimum procedure for inserting a peripheral venous catheter was defined based on three evidence-based guidelines (WHO, CDC, RKI including five steps with 1A or 1B level of evidence: hand disinfection before patient contact, skin antisepsis of the puncture site, no palpation of treated puncture site, hand disinfection before aseptic procedure, and sterile dressing on the puncture site. A research nurse observed and recorded procedures for peripheral venous catheter insertion for healthcare workers in four different departments (endoscopy, central emergency admissions, pediatrics, and dermatology. A multimodal intervention with 5 elements was established (teaching session, dummy training, e-learning tool, tablet and poster, and direct feedback, followed by a second observation period. During the last observation week, participants evaluated the intervention.Results: In the control period, 207 insertions were observed, and 202 in the intervention period. Compliance improved significantly for four of five steps (e.g., from 11.6% to 57.9% for hand disinfection before patient contact; p<0.001, chi-square test. Compliance with skin antisepsis of the puncture site was high before and after intervention (99.5% before and 99.0% after. Performance of specific steps in the correct order also improved (e.g., from 7.7% to 68

Catheter-related blood stream infections are a morbid complication of central venous catheters. This review will highlight a comprehensive approach demonstrated to prevent catheter-related blood stream infections. Elements of prevention important to inserting a central venous catheter include proper hand hygiene, use of full barrier precautions, appropriate skin preparation with 2% chlorhexidine, and using the subclavian vein as the preferred anatomic site. Rigorous attention needs to be given to dressing care, and there should be daily assessment of the need for central venous catheters, with prompt removal as soon as is practicable. Healthcare workers should be educated routinely on methods to prevent catheter-related blood stream infections. If rates remain higher than benchmark levels despite proper bedside practice, antiseptic or antibiotic-impregnated catheters can also prevent infections effectively. A recent program utilizing these practices in 103 ICUs in Michigan resulted in a 66% decrease in infection rates. There is increasing recognition that a comprehensive strategy to prevent catheter-related blood stream infections can prevent most infections, if not all. This suggests that thousands of infections can potentially be averted if the simple practices outlined herein are followed.

2006-02-15

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.

Advantages and disadvantages of peripherally inserted central venous catheters (PICC) compared to other central venous lines: a systematic review of the literature.

2013-06-01

The use of central venous lines carries a significant risk for serious complications and high economic costs. Lately, the peripherally inserted central venous catheter (PICC) has gained in popularity due to presumed advantages over other central venous lines. The aim of this systematic literature review was to identify scientific evidence justifying the use of PICC. The literature review was performed according to the principles of Cochrane Collaboration. The electronic literature search included common databases up to March 2011. Only those studies rated as high or moderate quality were used for grading of evidence and conclusions. The search resulted in 827 abstracts, 48 articles were read in full text, and 11 met the inclusion criteria. None of the articles was classified as high quality and two had moderate quality. The results of these two studies indicate that PICC increases the risk for deep venous thrombosis (DVT), but decreases the risk for catheter occlusion. The quality of scientific evidence behind these conclusions, however, was limited. Due to the lack of studies with sufficiently high quality, questions such as early complications, patient satisfaction and costs could not be answered. We conclude that although PICCs are frequently used in oncology, scientific evidence supporting any advantage or disadvantage of PICC when comparing PICC with traditional central venous lines is limited, apart from a tendency towards increased risk for DVT and a decreased risk for catheter occlusion with PICC.

With the increased use of implanted venous access devices (IVADs) for continuous long-term venous access, several techniques such as percutaneous endovascular fibrin sheath removal, have been described, to maintain catheter function. Most standard techniques do not capture the stripped fibrin sheath, which is subsequently released in the pulmonary circulation and may lead to symptomatic pulmonary embolism. The presented case describes an endovascular technique which includes stripping, capture, and removal of fibrin sheath using a novel filter device. A 64-year-old woman presented with IVAD dysfunction. Stripping was performed using a co-axial snare to the filter to capture the fibrin sheath. The captured fragment was subsequently removed for visual and pathological verification. No immediate complication was observed and the patient was discharged the day of the procedure.

Purpose: Approximately 200,000 central venous catheterizations are carried out annually in the National Health Service in the United Kingdom. Inadvertent arterial puncture occurs in up to 3.7%. Significant morbidity and death has been reported. We report on our experience in the endovascular treatment of this iatrogenic complication. Methods: Retrospective analysis was carried out of 9 cases referred for endovascular treatment of inadvertent arterial puncture during central venous catheterization over a 5 year period. Results: It was not possible to obtain accurate figures on the numbers of central venous catheterizations carried out during the time period. Five patients were referred with carotid or subclavian pseudoaneurysms and hemothorax following inadvertent arterial catheter insertion and subsequent removal. These patients all underwent percutaneous balloon tamponade and/or stent-graft insertion. More recently 4 patients were referred with the catheter still in situ and were successfully treated with a percutaneous closure device. Conclusion: If inadvertent arterial catheterization during central venous access procedures is recognized and catheters removed, sequelae can be treated percutaneously. However, once the complication is recognized it is better to leave the catheter in situ and seal the artery percutaneously with a closure device

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.

The majority of stem cell recipients rely on indwelling central venous catheters situated in superior vena cava or right atrium. Semi-permanent tunneled silicone rubber Hickman catheters are widely used to provide durable central venous access for patients undergoing stem cell transplantation. A case of 5 years old child with diagnosis of severe aplastic anemia is reported. The patient received peripheral blood stem cells (PBSC) and had successful engraftment with complete hematological recovery. He had Hickman catheter embolism in the pulmonary circulation following unsuccessful attempt to remove the line. The catherter was successfully removed by midsternostomy operation. The child is normal with sustained remission on day +218 post stem cell transplant. (author)

To develop and validate an educational digital video on changing the dressing of short-term, non-cuffed, non-tunneled central venous catheters in hospitalized adult patients. This is a descriptive, methodological study based on Paulo Freire's assumptions. The development of the script and video storyboard were based on scientific evidence, on the researchers' experience, and that of nurse experts, as well as on a virtual learning environment. The items related to the script were approved by 97.2% of the nurses and the video was approved by 96.1%. The educational instrument was considered to be appropriate and we believe it will contribute to professional training in the nursing field, the updating of human resources, focusing on the educational process, including distance education. We believe it will consequently improve the quality of care provided to patients with central venous catheters.

Abstract Background Regardless of active antifungal drugs, mortality of candidemia remains high. Although it is well-known that central venous catheter (CVC) is one of the most important risk factors of candidemia and should be removed immediately, little is known about optimal timing of CVC replacement after removal. Here, we analyzed contributing risk factors associated with 30-day mortality for catheter-related bloodstream infection (CRBSI) due to candida and optimal timing of CVC replacem...

Many complications of central venous catheters, which include perforation of the vessel walls and extravasation of the infusate into pericardial, pleural, and peritoneal cavities, have been reported. We report an infant with a central venous catheter in inferior vena cava who experienced extravasation of parenteral alimentation fluid into the right renal pelvis secondary to perforation of the renal vein. To our knowledge, this rare complication has not been reported earlier.

methodological procedures expected by Cochrane. We included six RCTs (1539 participants) in this review. Trial sizes ranged from 50 to 703 participants. These six trials made four comparisons, namely: transparent dressings versus gauze; bordered transparent dressings versus a securement device; bordered transparent dressings versus tape; and transparent dressing versus sticking plaster. There is very low quality evidence of fewer catheter dislodgements or accidental removals with transparent dressings compared with gauze (two studies, 278 participants, RR 0.40; 95% CI 0.17 to 0.92, P = 0.03%). The relative effects of transparent dressings and gauze on phlebitis (RR 0.89; 95% CI 0.47 to 1.68) and infiltration (RR 0.80; 95% CI 0.48 to 1.33) are unclear. The relative effects on PVC failure of a bordered transparent dressing and a securement device have been assessed in only one small study and these were unclear. There was very low quality evidence from the same single study of less frequent dislodgement or accidental catheter removal with bordered transparent dressings than securement devices (RR 0.14, 95% CI 0.03 to 0.63) but more phlebitis with bordered dressings (RR 8.11, 95% CI 1.03 to 64.02) (very low quality evidence). A small single study compared bordered transparent dressings with tape and found very low quality evidence of more PVC failure with the bordered dressing (RR 1.84, 95% CI 1.08 to 3.11) but the relative effects on dislodgement were not clear (very low quality evidence). The relative effects of transparent dressings and a sticking plaster have only been compared in one small study and are unclear. More high quality RCTs are required to determine the relative effects of alternative PVC dressings and securement devices. It is not clear if any one dressing or securement device is better than any other in securing peripheral venous catheters. There is a need for further, independent high quality trials to evaluate the many traditional as well as the newer, high use

Effectiveness of the transparent sterile dressing vs standard to fix the peripheral venous catheter (PVC), on the incidence of phlebitis. A randomized controlled trial. The type of dressing could contribute to the incidence of phlebitis, infiltration and accidental removals but the results of the studies are contrasting and samples are limited. To compare the effectiveness of a transparent polyurethane sterile dressing on the rate of phlebitis associated to peripheral venous catheter (PVC) vs a non sterile sticking plaster in use in current practice (standard dressing). Randomized controlled trial. Participants. 1061 PVCs (703 patients, adults and children) at a research orthopedic hospital in the north of Italy; 540 PVCs allocated to receive the sterile and 521 the standard dressing. 96 PVCs were excluded for phlebitis, 48 (9.6%) in the sterile and 48 (10.1%) in the standard dressing group, RR 0.96 (95%CI 0.697 - 1.335). Accidental removal of the PVCs was more frequent with the sterile dressing (9.6% vs 6.3%) but the number of catheters removed without complications was larger in the standard dressing group (48.9% vs 54.9% P=0.0503). Eighty-five PVCs were replaced for detachment of the dressing (50, 9.2% sterile and 35, 6.7% standard dressing). The cheapest transparent sterile dressing costs 32 cents while the standard 9 cents. A sticking non sterile plasters is not influential on the rate of phlebitis and ensures an good fix of the PVC compared the transparent sterile dressing to of polyurethane film.

Radiographic assessment of venous catheter position in children: Value of the lateral view

Stark, D.D.; Brasch, R.C.; Gooding, C.A.

1984-01-01

Frontal chest radiographs can be misleading in the evaluation of central venous catheter placement. Lateral chest radiographs were obtained, in addition to the standard frontal radiographs, in 25 young children. In five (20%) of the children, the catheters were found to be malpositioned, and the frontal radiograph showed evidence of the abnormality in all five. The lateral radiographs also showed evidence of the abnormality in all five children; however, in three of the five, the lateral radiographs provided additional, more specific, diagnostic information. The lateral chest radiographs also demonstrated satisfactory catheter positioning in three other children in whom the frontal radiographs suggested abnormal positioning. Accurate assessment of catheter position was possible in all patients using both frontal and lateral chest radiographs. Injection of contrast material was not necessary to locate malpositioned catheters. Lateral radiographs are recommended whenever an abnormal catheter position is suspected clinically or from findings on the routine frontal radiograph. (orig.)

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

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

Fibrin sheaths are a heterogeneous matrix of cells and debris that form around catheters and are a known cause of central venous stenosis and catheter failure. A total of 50 cases of central venous catheter fibrin sheath angioplasty (FSA) after catheter removal or exchange are presented. A retrospective review of an outpatient office database identified 70 eligible patients over a 19-month period. After informed consent was obtained, the dialysis catheter exiting the skin was clamped, amputated, and a wire was inserted. The catheter was then removed and a 9-French sheath was inserted into the superior vena cava, a venogram was performed. If a fibrin sheath was present, angioplasty was performed using an 8 × 4 or 10 × 4 balloon along the entire length of the fibrin sheath. A completion venogram was performed to document obliteration of the sheath. During the study, 50 patients were diagnosed with a fibrin sheath, and 43 had no pre-existing central venous stenosis. After FSA, 39 of the 43 patient's (91%) central systems remained patent without the need for subsequent interventions; 3 patients (7%) developed subclavian stenoses requiring repeat angioplasty and stenting; 1 patent (2.3%) developed an occlusion requiring a reintervention. Seven patients with prior central stenosis required multiple angioplasties; five required stenting of their central lesions. Every patient had follow-up fistulograms to document long-term patency. We propose that FSA is a prudent and safe procedure that may help reduce the risk of central venous stenosis from fibrin sheaths due to central venous catheters. PMID:23997555

To assess the effect of simulation training on pediatric residents' acquisition and retention of central venous catheter insertion skills. A secondary objective was to assess the effect of simulation training on self-confidence to perform the procedure. Prospective observational pilot study. Single university clinical simulation center. Pediatric residents, postgraduate years 1-3. Residents participated in a 60- to 90-minute ultrasound-guided central venous catheter simulation training session. Video recordings of residents performing simulated femoral central venous catheter insertions were made before (baseline), after, and at 3-month following training. Three blinded expert raters independently scored the performances using a 24-item checklist and 100-mm global rating scale. At each time point, residents rated their confidence to perform the procedure on a 100-mm scale. Twenty-six residents completed the study. Compared with baseline, immediately following training, median checklist score (54.2% [interquartile range, 40.8-68.8%] vs 83.3% [interquartile range, 70.0-91.7%]), global rating score (8.0 mm [interquartile range, 0.0-64.3 mm] vs 79.5 mm [interquartile range, 16.3-91.7 mm]), success rate (38.5% vs 80.8%), and self-confidence (8.0 mm [interquartile range, 3.8-19.0 mm] vs 52.0 mm [interquartile range, 43.5-66.5 mm]) all improved (p interquartile range, 40.8-68.8%] vs 54.2% [interquartile range, 45.8-80.4%], p = 0.47), global rating score (8.0 mm [interquartile range, 0.0-64.3 mm] vs 35.5 mm [interquartile range, 5.3-77.0], p = 0.62), and success rate (38.5% vs 65.4%, p = 0.35) were similar at 3-month follow-up. Self-confidence, however, remained above baseline at 3-month follow-up (8.0 mm [interquartile range, 3.8-19.0 mm] vs 61.0 mm [interquartile range, 31.5-71.8 mm], p < 0.01). Simulation training improved pediatric residents' central venous catheter insertion procedural skills. Decay in skills was found at 3-month follow-up. This suggests that

Cost-effectiveness of a central venous catheter care bundle.

Kate A Halton

Full Text Available BACKGROUND: A bundled approach to central venous catheter care is currently being promoted as an effective way of preventing catheter-related bloodstream infection (CR-BSI. Consumables used in the bundled approach are relatively inexpensive which may lead to the conclusion that the bundle is cost-effective. However, this fails to consider the nontrivial costs of the monitoring and education activities required to implement the bundle, or that alternative strategies are available to prevent CR-BSI. We evaluated the cost-effectiveness of a bundle to prevent CR-BSI in Australian intensive care patients. METHODS AND FINDINGS: A Markov decision model was used to evaluate the cost-effectiveness of the bundle relative to remaining with current practice (a non-bundled approach to catheter care and uncoated catheters, or use of antimicrobial catheters. We assumed the bundle reduced relative risk of CR-BSI to 0.34. Given uncertainty about the cost of the bundle, threshold analyses were used to determine the maximum cost at which the bundle remained cost-effective relative to the other approaches to infection control. Sensitivity analyses explored how this threshold alters under different assumptions about the economic value placed on bed-days and health benefits gained by preventing infection. If clinicians are prepared to use antimicrobial catheters, the bundle is cost-effective if national 18-month implementation costs are below $1.1 million. If antimicrobial catheters are not an option the bundle must cost less than $4.3 million. If decision makers are only interested in obtaining cash-savings for the unit, and place no economic value on either the bed-days or the health benefits gained through preventing infection, these cost thresholds are reduced by two-thirds. CONCLUSIONS: A catheter care bundle has the potential to be cost-effective in the Australian intensive care setting. Rather than anticipating cash-savings from this intervention, decision

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

Fernanda de Paula Rossini

Full Text Available ABSTRACT Objective: to evaluate the use of peripheral venous catheters based on microbiological analysis of devices (dressing and three-way stopcocks and thus contribute to the prevention and infection control. Methods: this was a prospective study of microbiological analysis of 30 three-way stopcocks (external surfaces and lumens and 30 dressing used in maintaining the peripheral venous catheters of hospitalized adult patients. Results: all external surfaces, 40% of lumens, and 86.7% of dressing presented bacterial growth. The main species isolated in the lumen were 50% coagulase-negative Staphylococcus, 14.3% Staphylococcus aureus, and 14.3% Pseudomonas aeruginosa. Fifty nine percent of multidrug-resistant bacteria were isolated of the three-way stopcocks, 42% of the lumens, and 44% of the dressing with a predominance of coagulase-negative Staphylococcus resistant to methicillin. Besides, 18% gram-negative bacteria with resistance to carbapenems were identified from multidrug-resistant bacteria on the external surfaces of the three-way stopcocks. Conclusion: it is important to emphasize the isolation of coagulase-negative Staphylococcus and gram-negative bacteria resistant to methicillin and carbapenems in samples of devices, respectively, which reinforces the importance of nursing care in the maintenance of the biologically safe environment as well as prevention and infection control practices.

Renal vein to renal collecting system fistula: An extreme complication from central venous thrombosis secondary to indwelling catheter

Directory of Open Access Journals (Sweden)

Aditya Safaya

2018-04-01

Full Text Available Central venous catheters are routinely used for resuscitation, chemotherapy and nutrition but are not without risk. Central lines are the most common extrinsic cause of venous thrombosis in neonates and infants. We present an ex-36 week 1800g infant baby girl recovering after a staged repair of gastroschisis with ileostomy and mucous fistula formation. The patient was receiving parenteral nutrition through an indwelling saphenous vein tunneled catheter, with its tip in the inferior vena cava. The patient developed polyuria, with a characteristic odor of the parenteral nutrition and a urine analysis showed glucose and triglyceride levels consistent with the composition of the parenteral nutrition fluid. A fluoroscopic cysto-urogram and an inferior vena-cavogram showed a catheter-associated inferior vena cava thrombosis leading to backpressure changes, diverting all intravenous contrast into the right renal vein and to renal collecting system, thus elucidating the route of the parenteral nutrition fluid reaching the bladder. Our case represents an extreme case of complicated central venous thrombosis. We emphasize the importance of practicing a high index of suspicion for thrombotic complications in severely ill neonates with central venous access. An early diagnosis and aggressive management may prevent progression of the disease towards an overwhelming complication.

Serious Complication of Central Venous Catheterization Due to Hemothorax: Hemothorax

Ümmügülsüm Gaygısız

2017-12-01

Full Text Available Central venous catheterization may cause life-threatening complications including pneumothorax and hemothorax. We report a case of multiple trauma complicated with an incidence of hemothorax due to a misplaced central venous catheter. Firstly, the tip of the guide-wire was ruptured in subcutaneous tissue and, secondly, the catheter came out of the vessel and caused hemothorax. During left subclavian catheterization, in this 47-years-old male patient, we could not advance the guide wire forward easily in the first attempt and tried to draw it back. In the second attempt, we inserted a new catheter without any difficulty. The blood gas analyses through the catheter for verification of location revealed its venous nature. After the catheterization, 500 mL hemorrhagic fluid was drained through the ipsilateral chest tube. Control chest X-ray showed that the catheter was in the left hemithorax and a piece of the guide wire was present below the left clavicle. Thorax computerized tomography showed that the catheter entered the thoracic cavity and extended to the paramediastinal region. An emergency surgery was performed to remove the piece of the guide wire and the catheter extending out of the vessel. A common method to check the intravenous insertion of a central catheter into a vein is to verify that the easily drawn blood has the nature of venous blood. This method, however, does not exclude the extravascular placement of the catheter in the presence of ipsilateral hemothorax.

To investigate the influence of the number of T-junctions between central venous catheter and pressure transducer on measurement of central venous pressure ( CVP ) in patients. A prospective controlled study was conducted. The patients with CVP monitoring in Department of Critical Care Medicine of the Fifth Center Hospital in Tianjin from February to October in 2014 were enrolled. The patients were divided into three groups according to the number of T-junction between central venous catheter and pressure transducer: without T-junction control group and 1, 2, 3 T-junctions groups. In each patient, corresponding CVP values with different number of T-junctions placed between the central venous catheter and pressure sensors were determined within a certain period, and a square-wave graphic was obtained and preserved on the monitor. The own frequency ( fn ) and the attenuation coefficient ( D ) of the system of pressure measurement were calculated after measurement of the shock wave following a square-wave to obtain the distance between two vibrations and the amplitude of the shock wave. The difference in CVP, fn and D were compared among the groups. A total of 20 cases were enrolled, and 150 groups of data were collected. (1) With the increase in the number of T-junction, CVP showed a tendency of gradual reduction. The CVP of the groups of control and 1, 2, 3 T-junctions was ( 7.00±1.60 ), ( 7.00±3.00 ), ( 5.00±2.00 ), and ( 4.00±1.00 ) mmHg ( 1 mmHg = 0.133 kPa ), respectively. The CVP of 3 T-junctions group was significantly lower than that of the control group ( F = 9.333, P = 0.015 ). (2) With an increase in the number of T-junction, fn showed a tendency of gradual increase. The fn of groups control and 1, 2, 3 T-junctions was ( 12.30±0.79 ), ( 16.00±0.91 ), ( 18.10±1.75 ), ( 20.90±2.69 ) Hz, respectively. The fn of 1, 2, 3 T-junctions group was significantly higher than that of the control group ( F1 = 45.962, F2 = 45.414, F3 = 46.830, all P = 0

As the population of people with cancer increases so does the number of patients who take chemotherapy. Majority of them are administered parentally continuously. Implantable central venous catheter device is a good choice for those patients; however, severe complication would occur concerning the devices. Pinch-off syndrome is one of the most severe complications. The authors report a severe case of pinch-off syndrome. The patient with the implantable central venous device could not take chemotherapy because the device occluded. Further examination revealed the transection of the catheter. The transected fragment of the catheter in the heart was successfully removed by using a loop snare placed through the right femoral vein.

Peripheral venous catheter insertion is a procedural skill that every medical student should master. Training is often limited to a small number of students and is poorly evaluated. The objective of this study was to evaluate the performance of peer-assisted learning in comparison to instructor-led teaching for peripheral venous catheter insertion training. Students were randomized to the control group attending a traditional instructor-led training session (slideshow and demonstration by an anesthetist instructor, followed by training on a procedural simulator) or to the test group attending a peer-assisted training session (slideshow and demonstration video-recorded by the same instructor, followed by training on a procedural simulator). The primary endpoint was the performance of peripheral venous catheter insertion, assessed on procedural simulator one week later by blinded experts using a standardized 20-item grid. Students self-evaluated their confidence levels using a numeric 10-point scale. Eighty-six students were included, 73 of whom attended the assessment session. The median performance score was 12/20 [8-15] in the instructor-led teaching group versus 13/20 [11-15] in the peer-assisted learning group (P=0.430). Confidence levels improved significantly after the assessment session and were significantly higher in the peer-assisted learning group (7.6/10 [7.0-8.0] versus 7.0/10 [5.0-8.0], P=0.026). Peer-assisted learning is effective for peripheral venous catheter insertion training and can be as effective as instructor-led teaching. Given the large number of students to train, this finding is important for optimizing the cost-effectiveness of peripheral venous catheter insertion training.

An 84-year-old woman underwent Convex-probe Endobronchial Ultrasound (CP-EBUS) for 18 F-fluorodeoxyglucose avid subcarinal lymphadenopathy on Positron Emission Tomogram (PET) scan. Endobronchial ultrasound-guided transbronchial needle aspiration of the subcarinal lymph node revealed squamous cell lung carcinoma. A small hyperechoic rounded density was noted inside the lumen of the azygous vein. Based on chest computed tomography findings and her clinical history, this was felt to be a broken fragment of a peripherally inserted central catheter, which was placed for intravenous antibiotics, a few months prior to this presentation. To the best of our knowledge, this is the first ever CP-EBUS description of a broken fragment of central venous catheter. © 2016 John Wiley & Sons Ltd.

We examine the complication and continence rates with early catheter removal (day 3 or 4) after radical retropubic prostatectomy. A total of 365 patients with localized prostate cancer underwent radical retropubic prostatectomy at Indiana University Hospital with planned urethral catheter removal before discharge home. Low pressure cystograms were performed on postoperative day 3 or 4 to determine if catheter removal was possible. A subset of patients were analyzed using a validated prostate cancer specific questionnaire (University of California, Los Angeles Prostate Cancer Symptom Index) to determine quality of life outcomes. The catheter was removed on postoperative day 3 or 4 in 263 patients (72%). The reasons for leaving the catheter indwelling were significant leak on cystogram or excessive suprapubic drainage (21%), extensive bladder neck reconstruction (1%) and prolonged hospitalization because of an ileus or other complicating factor (6%). Thirteen patients (3.6%) were either unable to void after catheter removal or presented with retention (not associated with hematuria or clots) after hospital discharge, requiring reinsertion of the Foley catheter. A total of 41 patients (11%) had either an early or late complication (excluding incontinence). There were 3 complications (0.8%) that were considered major because they were potentially life threatening or required a return to the operating room. A pelvic abscess developed in 2 patients and a lymphocele in 1, which required percutaneous drainage. After at least 6 months (mean 20.9 months) 140 patients (89.2%) and 14 (8.9%) reported excellent and good continence, respectively. The patient questionnaire demonstrated bother scores to be minimal to no bother for 95% to 98% of patients at 6 and 12 months. This study confirms that it is safe to remove catheters in most patients 3 to 4 days after prostatectomy if a cystogram demonstrates no extravasation. Complication rates and continence rates with this approach

ABSTRACT Objective: to evaluate the use of peripheral venous catheters based on microbiological analysis of devices (dressing and three-way stopcocks) and thus contribute to the prevention and infection control. Methods: this was a prospective study of microbiological analysis of 30 three-way stopcocks (external surfaces and lumens) and 30 dressing used in maintaining the peripheral venous catheters of hospitalized adult patients. Results: all external surfaces, 40% of lumens, and 86.7% of dressing presented bacterial growth. The main species isolated in the lumen were 50% coagulase-negative Staphylococcus, 14.3% Staphylococcus aureus, and 14.3% Pseudomonas aeruginosa. Fifty nine percent of multidrug-resistant bacteria were isolated of the three-way stopcocks, 42% of the lumens, and 44% of the dressing with a predominance of coagulase-negative Staphylococcus resistant to methicillin. Besides, 18% gram-negative bacteria with resistance to carbapenems were identified from multidrug-resistant bacteria on the external surfaces of the three-way stopcocks. Conclusion: it is important to emphasize the isolation of coagulase-negative Staphylococcus and gram-negative bacteria resistant to methicillin and carbapenems in samples of devices, respectively, which reinforces the importance of nursing care in the maintenance of the biologically safe environment as well as prevention and infection control practices.

Full Text Available The application of the central venous catheter (CVC as a temporary orpermanent vascular approach to hemodialysis has been practiced in our Center since1994. So far 30 (12,6% patients have been thus treated. The primary application hasbeen done in 25 patients, namely: the first making of the A V fistula has been done in16, the ABT in 6, while the vascular approach correction in 3 patients. The secondaryapplication has been done in 5 patients. The infection episode incidence concerningthe CVC application is 20 infections per 1.000 patients. This is the upper limitaccording to the data given in the literature (5, rang 3-20. The average duration of thecatheter is 21 + - 13 days (rang 1-47. Two-volume catheters have been used for ajugular approach though less often for a femoral one. The unsuccessful placing due tothe catheter thrombosis has occurred in 4 patients, the catheter drop-out and itsreplacing have been done in 2 patients, while no replacement has happened in onečaše. The treatment has been stopped in one patient. Tn four patients the cerebrovascularinsult has happened after placing the CVC. The mortality rate is 26,6%,that is, K patients, namely: 4 due to cerebrovascular insult, one due to lung emboly,one due to heart weakness and one due to the sepsis from the V fistula. One patientdied at home for unknown reason. A high infection episode incidence rate is related toinadequate patients' placing so that their location in the rooms for intensive care is away of reducing it. It is necessary to provide for general aseptic procedure at work aswell as for betterment of the accompanying procedures (hemoculture, antibiograms,sterilization in order to maintain a safe catheter function.

Purpose: To perform a retrospective outcomes analysis of central venous catheters with peripheral venous access ports, with comparison to published data.Methods: One hundred and twelve central venous catheters with peripherally placed access ports were placed under sonographic guidance in 109 patients over a 4-year period. Ports were placed for the administration of chemotherapy, hyperalimentation, long-term antibiotic therapy, gamma-globulin therapy, and frequent blood sampling. A vein in the upper arm was accessed in each case and the catheter was passed to the superior vena cava or right atrium. Povidone iodine skin preparation was used in the first 65 port insertions. A combination of Iodophor solution and povidone iodine solution was used in the last 47 port insertions. Forty patients received low-dose (1 mg) warfarin sodium beginning the day after port insertion. Three patients received higher doses of warfarin sodium for preexistent venous thrombosis. Catheter performance and complications were assessed and compared with published data.Results: Access into the basilic or brachial veins was obtained in all cases. Ports remained functional for a total of 28,936 patient days. The port functioned in 50% of patients until completion of therapy, or the patient's expiration. Ports were removed prior to completion of therapy in 18% of patients. Eleven patients (9.9% of ports placed) suffered an infectious complication (0.38 per thousand catheter-days)-in nine, at the port implantation site, in two along the catheter. In all 11 instances the port was removed. Port pocket infection in the early postoperative period occurred in three patients (4.7%) receiving a Betadine prep vs two patients (4.2%) receiving a standard O.R. prep. This difference was not statistically significant (p = 0.9). Venous thrombosis occurred in three patients (6.8%) receiving warfarin sodium and in two patients (3%) not receiving warfarin sodium. This difference was not statistically significant

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

Sipuleucel-T is an autologous cellular immunotherapy. We review the safety of the leukapheresis procedure required for sipuleucel-T preparation and complications related to venous catheter use in the randomized, placebo controlled phase 3 IMPACT (IMmunotherapy for ProstAte Cancer Trial) study (NCT 00065442). A total of 512 patients with asymptomatic or minimally symptomatic metastatic castrate resistant prostate cancer were enrolled in the study. All patients were scheduled to undergo 3 standard 1.5 to 2.0 blood volume leukapheresis procedures at 2-week intervals. Leukapheresis related adverse events and those related to venous catheter use were reviewed. Immune cell counts were examined throughout the treatment course. Of 512 enrolled patients 506 underwent 1 or more leukapheresis procedures and were included in this analysis. Adverse events were comparable between the sipuleucel-T and control arms. Leukapheresis related adverse events were primarily associated with transient hypocalcemia (39.3%). Most leukapheresis related adverse events (97%) were of mild/moderate intensity. Median white blood cell count and absolute monocyte and lymphocyte counts were stable and within normal ranges throughout the treatment course. Of all patients 23.3% had a central venous catheter placed primarily for leukapheresis. Patients with vs without a central venous catheter had a higher risk of infection potentially related to catheter use (11.9% vs 1.3%, p nervous system (5.9% vs 2.1%, p = 0.06). Adverse events related to leukapheresis are manageable and quickly reversible. The majority of patients can undergo leukapheresis without a central venous catheter. Central venous catheters are associated with an increased risk of infections and venous vascular events. Peripheral intravenous access should be used when feasible.

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 (Pcatheterization (Pcatheterization and internal jugular vein catheterization (Pvenous thrombosis history (Pvenous 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.

Peripherally inserted central catheters (PICCs) are considered a safe method to provide long-term antibiotic therapy, chemotherapy and nutrition support. Deep venous thrombosis (DVT) is a complication that requires early PICC removal, may extend hospitalization and can result in pulmonary embolism. PICC insertion teams strive to understand risk factors and develop methods to prevent DVTs. However, they can only manage what they can measure. At LDS Hospital, identification of PICC associated DVTs was dependent on verbal notification or manual surveillance of more than a thousand free-text vascular reports. Accurate DVT rates were not known which hindered prevention. We describe the development of a computer application (PICC-DVT monitor) to identify PICC associated DVTs each day. A one-year evaluation of the monitor by the PICC team and a review of 445 random vascular reports found a positive predictive value of 98%, sensitivity of 94%, specificity of 100% and a PICC team associated DVT rate of 2.8%.

We describe a central venous catheter-related (Port-A-Cath; Smiths Industries Medical Systems [SIMS] Deltec, Inc., St. Paul, Minn.) infection caused by Rhodotorula glutinis in a 51-year-old man with nasopharyngeal carcinoma. He was treated with fluconazole for 8 weeks and had the catheter removed. Two isolates of R. glutinis recovered from blood specimens (one obtained via peripheral veins and one via the catheter) before administration of fluconazole and one recovered from the removed catheter 17 days after initiation of fluconazole therapy exhibited high-level resistance to fluconazole (MICs, >256 μg/ml). These three isolates were found to belong to a single clone on the basis of identical antibiotypes determined by the E test (PDM Epsilometer; AB Biodisk, Solna, Sweden) and biotypes determined by API ID32 C (bioMerieux, Marcy I'Etoile, France) and their identical random amplified polymorphic DNA patterns.

Inferior vena cava (IVC) filters can present challenges to emergency physicians in the process of central venous catheter (CVC) placement. A 68-year-old woman presented to the emergency department with severe shortness of breath and was intubated. A central line was placed after the intubation to facilitate peripheral access. A CVC guidewire unraveled during placement after getting caught on an IVC filter. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be aware of the complications that IVC filters can cause in the placement of CVCs. Imaging and identification of IVC filters beforehand will allow for proper planning of how to manage the case in which a filter catches on the guidewire. Simple anecdotal techniques, such as advancing the guidewire and spinning the guidewire between the fingers, can facilitate the removal of the guide wire from the IVC filter.

Full Text Available SUMMARY: Objectives: In emergency departments, emergency physicians frequently have to perform central venous access. In cases where peripheral venous access is not possible, central venous access is required for dialysis, fulfillment of urgent fluid need, or central venous pressure measurement. This study was carried out to evaluate the emergence of complications in the process of and in the 15 days following the insertion of central venous catheter under ultrasound guidance in the emergency department. Methods: For this study, patients who presented to the emergency department over a period of eight months with an urgent need for central catheter were examined prospectively. Age, gender, and accompanying diseases of patients as well as the type, time, duration, and indication of the venous access were recorded. Furthermore, the amount of experience of the physician was taken into consideration. Results: In the emergency department, physicians performed ultrasound-guided central venous catheter insertion for 74 patients (40 men and 34 women. For access, internal jugular vein was used in 65 (87.8% patients, and femoral vein was used in 9 (12.2% patients. The reason for access was urgent dialysis need in 55 (74.3%, CVP measurement in 3 (4.1%, fluid support due to severe hypovolemia in 6 (8.1%, and difficulty of peripheral venous access in 10 (13.5% patients. None of the patients developed complications in the process of or after the insertion. Patients did not have infections related to the catheter in 15 days following the insertion. Conclusions: Central venous access is frequently required in emergency departments. The risk of complication is little if any in ultrasonographyguided access carried out under appropriate conditions.

The ISP (Safe Insertion of PICCs) protocol: a bundle of 8 recommendations to minimize the complications related to the peripherally inserted central venous catheters (PICC). The insertion of a peripherally inserted central venous catheter (PICC) is not without risks. The Italian Group for the Study of Long-Term Central Venous Access Devices (GAVeCeLT) has developed a protocol (SIP: Safe Implantation of PICCs) with the aim of minimizing the risks which may be associated with the placement of PICCs. The protocol is based on recommendations available in the literature and on the main clinical practice guidelines. The SIP protocol, a bundle of evidence-based recommendations, it is is easy to use, inexpensive, and cost-effective. If routinely used and carefully inplemented, it greatly reduces complications such as failure of venipuncture, accidental arterial puncture, damage of median nerve, infection and catheter related venous thrombosis.

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.

Autologous peripheral blood hematopoietic progenitor cell collection (A-HPCC) in children typically requires placement of a central venous catheter (CVC) for venous access. There is scant published data regarding the performance and safety of femoral CVCs in pediatric A-HPCC. Seven-year, retrospective study of A-HPCC in pediatric patients collected between 2009 and January 2017. Inclusion criteria were an age ≤ 21 years and A-HPCC using a femoral CVC for venous access. Femoral CVC performance was examined by CD34 collection rate, inlet rate, collection efficiency (MNC-FE, CD34-FE), bleeding, flow-related adverse events (AE), CVC removal, and product sterility testing. Statistical analysis and graphing were performed with commercial software. A total of 75/119 (63%) pediatric patients (median age 3 years) met study criteria. Only 16% of children required a CVC for ≥ 3 days. The CD34 collect rate and CD34-FE was stable over time whereas MNC-FE decreased after day 4 in 80% of patients. CD34-FE and MNC-FE showed inter- and intra-patient variability over time and appeared sensitive to plerixafor administration. Femoral CVC showed fewer flow-related AE compared to thoracic CVC, especially in pediatric patients (6.7% vs. 37%, P = 0.0005; OR = 0.12 (95%CI: 0.03-0.45). CVC removal was uneventful in 73/75 (97%) patients with hemostasis achieved after 20-30 min of pressure. In a 10-year period, there were no instances of product contamination associated with femoral CVC colonization. Femoral CVC are safe and effective for A-HPCC in young pediatric patients. Femoral CVC performance was maintained over several days with few flow-related alarms when compared to thoracic CVCs. © 2017 Wiley Periodicals, Inc.

2013-11-01

The recent proliferation of deep vein thrombosis in children has been attributed to the increased use of central venous catheters, specifically tunneled lines and peripherally inserted central catheters. A formal comparison of the incidence rate for deep vein thrombosis between tunneled lines and peripherally inserted central catheters has not been undertaken. Children inclusion. Data were extracted from the hospital discharge database which includes data on all procedures and up to 20 diagnoses per admission. Diagnoses and procedures were identified by International Classification of Disease, Ninth Revision coding. Patients were excluded if they received more than one central line. Data collected included type of central line, deep vein thrombosis event, and underlying medical illnesses classified according to chronic complex conditions. Over the seven year study period there was an overall rate of 73 deep vein thromboses per 10,000 hospital discharges. Of the 6915 eligible subjects, 181 had a deep vein thrombosis for an overall incidence rate of 2.6%. There were 152 thrombi (2.6%) in subjects with peripherally inserted central catheters and 29 thrombi (3.1%) in subjects with tunneled lines [OR=.83 (0.55, 1.29), p=0.38]. Despite the relative ease and simplicity of use of peripherally inserted central catheters leading to a substantial rise in their use, this study demonstrates that such lines pose a substantial risk for venous thrombosis and no difference in incidence was detected between such lines and tunneled lines. © 2013.

During the past 15 years, strategies that promote immediate and complete thrombus removal have gained popularity for the treatment of acute-onset iliofemoral deep venous thrombosis. In this case report, we describe a novel operative approach to venous thrombus removal known as hybrid operative thrombectomy. The technique employs a direct inguinal approach with concomitant retrograde advancement of a balloon catheter by femoral venotomy. Moreover, it provides effective thrombus removal through a single incision, with or without stent placement, and has the advantage of a completion venogram.

. "Let me tell you about my little box": phenomenological study on the experience of living with a totally implantable central venous catheter. Many variables impact on the choice to implant a totally implantable long-term central venous catheter's (Port), in spite of its proven efficacy. The patients' perception is pivotal, and only few qualitative studies dig deep into patients' feelings and experiences. To understand if, and how, the Port affects the patient's life. Qualitative phenomenological study based on semi-structured interviews on a convenience sample of patients implanted a Port, selected in an oncohematology Day Hospital in Milan. The analysis was carried out by three researchers with a phenomenological method. Four main themes, and sub-themes, emerged from twenty interviews. Relief, both physical and psychological; the process of the choice of inserting the Port and the importance of thinking about its positioning since the beginning of the treatment course; the symbol- the device reminds of the disease and its removal is of utmost importance; the technology progresses- the need of trust in the health care personnel and in their competences. The Port improved the patients' quality of life. The study allows some reflections on the need of considering the actual and future conditions of the patient to make a shared and informed choice.

Twenty dogs with neoplasms requiring multiple radiation treatments received either percutaneous vascular access catheters (PVACs; Cook, Bloomington, IN) or subcutaneous vascular access ports (SVAPs; Vascular-Access-Ports, Norfolk Medical Products, Inc., Skokie, IL); 10 dogs were entered in each group. All catheters were implanted and removed aseptically and the catheter tips were cultured during implant removal. Complications with PVACs included mild incisional swelling and redness and accidental severance or rupture of the catheter. Complications with SVAPs included incisional or port swelling, bruising or redness, hematoma formation, and pain. Ports in 4 of these dogs could not be used for 1 to 3 days after surgery because of swelling and pain. Surgical wound complications, when pooled for comparison, occurred significantly more frequently with the SVAPs (P = .023). Wound complications associated with both catheters were self-limiting and resolved within 7 days. Bacterial cultures were positive in two PVACs and four SVAP tips, however, none of these dogs had clinical signs of infection or sepsis. Although both types of indwelling catheters were functional in a clinical setting, PVACs were preferred to SVAPs for dogs undergoing radiation therapy because of decreased time for implantation and fewer overall complications

Full Text Available Introduction: Anticoagulation and antiplatelet therapy in the presence of the epidural catheter is still controversial. It is well known that dual antiplatelet therapy is indicated for 12 months after the placement of drug-eluting stents (DES. Removal of an epidural catheter during that period is related to an increased risk of stent occlusion in case of discontinuation of platelet function inhibitors or, on the other hand, increased risk of epidural hematoma associated with neurological deficit if suppressed platelet function is still present. Case Report: Here we present a case of a 63-year-old man who was admitted to Institute for Cardiovascular Diseases Dedinje for elective aortic surgery. Before the induction, an epidural catheter was inserted at the Th10-Th11 epidural space. Uneventful surgery was performed under the combined epidural and general anesthesia. On the 2nd postoperative day, the patient sustained a ST depression myocardial infarction treated with percutaneous coronary intervention with DES placement, while epidural catheter was still in place. Dual antiplatelet therapy with 600mg of clopidogrel, 100 mg of acetilsalicylic acid (ASA and low molecular weight heparin (LMWH were started during the procedure. The next day, clopidogrel (75 mg and ASA (100 mg were continued as well as LMWH. The decision to remove the epidural catheter was made on the 9th postoperative day, after platelet aggregation assays were performed. Six hours after catheter removal the patient again received clopidogrel, ASA and LMWH. There were no signs of epidural hematoma. Conclusion: This case shows that point-of-care testing with platelet aggregation assays may be useful in increasing the margin of safety for epidural catheter removal during dual antiplatelet therapy.

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

Full Text Available Peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication, and few cases have been reported in children. We report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. Catheter fragments may cause complications such as cardiac perforation, arrhythmias, sepsis, and pulmonary embolism. A 12-year-old female received chemotherapy for acute lymphocytic leukemia through a central venous port implanted into her right subclavian area. The patient completed chemotherapy without complications 6 months ago. Venous port was accidentally fractured during its removal. Chest radiographs of the patient revealed intracardiac catheter fragment extending from the right subclavian to the right atrium (RA and looping in the RA. The procedure was performed under ketamine and midazolam anesthesia and fluoroscopic guidance using a percutaneous femoral vein approach. A snare with triple loops (10 mm in diameter was used to successfully retrieve the catheter fragments without any complication. Percutaneous transcatheter retrieval of catheter fragments is occasionally extremely useful and should be considered by interventional cardiologists for retrieving migrated catheters and can be chosen before resorting to surgery, which has potential risks related to thoracotomy, cardiopulmonary bypass, and general anesthesia.

Janete de Souza Urbanetto

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

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. 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. 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. 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.

Arterio-venous fistulas may develop spontaneously, following trauma or infection, or be iatrogenic in nature. We present a rare case of a jejunal arterio- venous fistula in a 35-year-old man with a history of pancreatic head resection that had been performed two years previously because of chronic pancreatitis. The patient was admitted with acute upper abdominal pain, vomiting and an abdominal machinery-type bruit. The diagnosis of a jejunal arterio-venous fistula was established by MR imaging. Transfemoral angiography was performed to assess the possibility of catheter embolization. The angiographic study revealed a small aneurysm of the third jejunal artery, abnormal early filling of dilated jejunal veins and marked filling of the slightly dilated portal vein (13-14 mm). We considered the presence of segmental portal hypertension. The patient was treated with coil embolization in the same angiographic session. This case report demonstrates the importance of auscultation of the abdomen in the initial clinical examination. MR imaging and color Doppler ultrasound are excellent noninvasive tools in establishing the diagnosis. The role of interventional radiological techniques in the treatment of early portal hypertension secondary to jejunal arterio-venous fistula is discussed at a time when this condition is still asymptomatic. A review of the current literature is included

Declotting a Thrombosed Brescia-Cimino Fistula by Manual Catheter-Directed Aspiration of the Thrombus

International Nuclear Information System (INIS)

Turmel-Rodrigues, Luc A

2005-01-01

Acute thrombosis of native fistulae for hemodialysis occurs more rarely than for prosthetic grafts. The vascular access should be reopened as soon as possible in order to resume regular dialysis and to avoid resorting to a temporary central line. Manual aspiration is one of the numerous methods described in this setting. Clinical examination is essential to rule out local infection, which is the only serious contraindication to percutaneous maneuvers. Two introducer-sheaths are placed in a criss-cross fashion in order to gain access to the venous outflow and to the anastomosis. Access to the venous outflow is performed first in order to check the proximal extent of the thrombosis. Heparin and antibiotics are injected systemically. A similar maneuver is then performed in the direction of the anastomosis. The aspiration phase is then initiated. A 7-9 Fr aspiration catheter is pushed through the 'venous' introducer. Manual aspiration is created through a 50 ml syringe while the catheter is progressively removed with back and forth movements. The catheter and the contents of the syringe are flushed through a gauze on the working table to evaluate the amount of thrombus which has been removed and the maneuver is repeated as often as necessary to remove all the thrombus. Once all the clots located downstream from the venous introducer have been removed, any unmasked underlying stenosis is NOT dilated at this stage since it provides protection against major embolism coming from the inflow. The aspiration catheter is then pushed through the 'arterial' introducer down to the anastomosis in order to aspirate the thrombus located between the tip of the introducer and the anastomosis. Dilatation of unmasked stenoses is finally performed using high-pressure balloons. The holes made by the two introducers are closed using a U-shaped suture with interposition of a short piece of plastic and the patient is sent back to the nephrologists for dialysis

Central venous access plays an important role in the management of an ever-increasing population of patients ranging from those that are critically ill to patients with difficult clinical access. Interventional radiologists are key in delivering this service and should be familiar with the wide range of techniques and catheters now available to them. A comprehensive description of these catheters with regard to indications, technical aspects of catheterization, success rates, and associated early and late complications, as well as a review of various published guidelines on central venous catheter insertion are given in this article

To assess whether immediate (0h), intermediate (after 6h) or delayed (after 24h) removal of an indwelling urinary catheter after uncomplicated abdominal hysterectomy can affect the rate of re-catheterization due to urinary retention, rate of urinary tract infection, ambulation time and length of hospital stay. Prospective randomized controlled trial conducted at Suez Canal University Hospital, Egypt. Two hundred and twenty-one women underwent total abdominal hysterectomy for benign gynecological diseases and were randomly allocated into three groups. Women in group A (73 patients) had their urinary catheter removed immediately after surgery. Group B (81 patients) had the catheter removed 6h post-operatively while in group C (67 patients) the catheter was removed after 24h. The main outcome measures were the frequency of urinary retention, urinary tract infections, ambulation time and length of hospital stay. There was a significantly higher number of urinary retention episodes requiring re-catheterization in the immediate removal group compared to the intermediate and delayed removal groups (16.4% versus 2.5% and 0% respectively). Delayed urinary catheter removal was associated with a higher incidence of urinary tract infections (15%), delayed ambulation time (10.3h) and longer hospital stay (5.6 days) compared to the early (1.4%, 4.1h and 3.2 days respectively) and intermediate (3.7%, 6.8h and 3.4 days respectively) removal groups. Removal of the urinary catheter 6h postoperatively appears to be more advantageous than early or late removal in cases of uncomplicated total abdominal hysterectomy.

Full Text Available Purpose : Central venous catheters (CVCs though indispensable in current medical and intensive care treatment, also puts patients at risk of catheter related infection (CRI resulting in increased morbidity and mortality. We analysed the incidence, risk factors, bacteriological profile and antimicrobial susceptibility pattern of the isolates in central venous catheter associated bloodstream infection (CVC-BSI in the intensive care unit (ICU patients and studied the formation of biofilm in CVCs. Materials and Methods: The following case control study included 115 patients with CVC in situ. Quantitative blood cultures (QBC and catheter tip cultures were performed for the diagnoses. Direct catheter staining was done for an early diagnosis by acridine orange (AO and Gram staining methods. Biofilm production in catheters was detected by ′tissue culture plate′ (TCP method. The results were analysed using the computer-based program statistical package for the social sciences (SPSS. Results : In 25/115 patients, definite diagnosis of CVC-BSI was made. The mean age was 48.44 ± 17.34 years (cases vs 40.10 ± 18.24 years (controls and the mean duration of catheterisation was 25.72 ± 8.73 days (cases vs 11.89 ± 6.38 days (controls. Local signs of infection (erythema, tenderness and oozing were found more significantly in CVC-BSI cases. The AO staining was more sensitive and Gram staining of catheters showed higher specificity. Staphylococcus aureus followed by Pseudomonas aeruginosa and non-albicans Candida were common CVC-BSI pathogens. Multidrug-resistant (MDR strains were isolated in bacterial agents of CVC-BSI. Non-albicans Candida and Enterococcus faecalis showed strong biofilm production. Conclusion : The incidence of CVC-BSI was 21.73% and the rate was 14.59 per 1000 catheter days. Prolonged ICU stay and longer catheterisation were major risk factors. S. aureus was isolated most commonly in CVC-BSI cases. The menace of multidrug resistance and

Perioperative physicians occasionally encounter situations where central venous catheters placed preoperatively turn out to be unnecessary. The purpose of this retrospective study is to identify the unnecessary application of central venous catheter placement and determine the factors associated with the unnecessary application of central venous catheter placement. Using data from institutional perioperative central venous catheter surveillance, we analysed data from 1,141 patients who underwent central venous catheter placement. We reviewed the central venous catheter registry and medical charts and allocated registered patients into those with the proper or with unnecessary application of central venous catheter according to standard indications. Multivariate analysis was used to identify factors associated with the unnecessary application of central venous catheter placement. In 107 patients, representing 9.38% of the overall population, we identified the unnecessary application of central venous catheter placement. Multivariate analysis identified emergencies at night or on holidays (odds ratio [OR] 2.109, 95% confidence interval [95% CI] 1.021-4.359), low surgical risk (OR=1.729, 95% CI 1.038-2.881), short duration of anesthesia (OR=0.961/10min increase, 95% CI 0.945-0.979), and postoperative care outside of the intensive care unit (OR=2.197, 95% CI 1.402-3.441) all to be independently associated with the unnecessary application of catheterization. Complications related to central venous catheter placement when the procedure consequently turned out to be unnecessary were frequently observed (9/107) compared with when the procedure was necessary (40/1034) (p=0.032, OR=2.282, 95% CI 1.076-4.842). However, the subsequent multivariate logistic model did not hold this significant difference (p=0.0536, OR=2.115, 95% CI 0.988-4.526). More careful consideration for the application of central venous catheter is required in cases of emergency surgery at night or on

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.

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

Directory of Open Access Journals (Sweden)

Fadi Al Akhrass

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

2017-04-01

The post thrombotic syndrome is one of the most dreaded complications of proximal deep vein thrombosis. This syndrome leads to pain and suffering with leg swelling, recalcitrant ulceration and venous claudication which greatly impairs mobility and quality of life. The prevalence can be high in patients with iliofemoral venous involvement particularly in the setting of a proximal venous stenosis, such as occurs in May Thurner syndrome. Anticoagulation alone does not reduce the likelihood of this outcome. Compression therapy may be effective but garment discomfort limits its implementation. Pharmacomechanical thrombectomy, which combines catheter-directed thrombolysis with mechanical thrombus dissolution, provides an attractive treatment strategy for such patients. The rationale and delivery of pharmacomechanical thrombectomy, including patient selection and adjunctive antithrombotic therapy, will be reviewed in addition to tips and tricks for managing difficult patient scenarios. © 2017 John Wiley & Sons Ltd.

Loubani, Osama M; Green, Robert S

2015-06-01

The aim of this study was to collect and describe all published reports of local tissue injury or extravasation from vasopressor administration via either peripheral intravenous (IV) or central venous catheter. A systematic search of Medline, Embase, and Cochrane databases was performed from inception through January 2014 for reports of adults who received vasopressor intravenously via peripheral IV or central venous catheter for a therapeutic purpose. We included primary studies or case reports of vasopressor administration that resulted in local tissue injury or extravasation of vasopressor solution. Eighty-five articles with 270 patients met all inclusion criteria. A total of 325 separate local tissue injury and extravasation events were identified, with 318 events resulting from peripheral vasopressor administration and 7 events resulting from central administration. There were 204 local tissue injury events from peripheral administration of vasopressors, with an average duration of infusion of 55.9 hours (±68.1), median time of 24 hours, and range of 0.08 to 528 hours. In most of these events (174/204, 85.3%), the infusion site was located distal to the antecubital or popliteal fossae. Published data on tissue injury or extravasation from vasopressor administration via peripheral IVs are derived mainly from case reports. Further study is warranted to clarify the safety of vasopressor administration via peripheral IVs. Copyright © 2015 Elsevier Inc. All rights reserved.

Risk factors for central venous catheter-related infections in a neonatal population – systematic review

Directory of Open Access Journals (Sweden)

Viviane Rosado

2018-01-01

Full Text Available Objective: This was a systematic review of the incidence density and risk factors for central venous catheter-related infections in a neonatal population. Data source: The MEDLINE, Embase, Cochrane, BDENF, SciELO, and LILACS databases were used without date or language restriction. Studies that analyzed risk factors for bloodstream infections in newborns were identified. Data synthesis: A total of 134 articles were found that met the eligibility criteria. Of these articles, 14 were selected that addressed risk factors for central venous catheter-related infection in neonates. Catheter-related bloodstream infections remain an important complication, as shown by the incidence rates reported in the studies included in this review. The observed risk factors indicate that low birth weight, prematurity, and longer catheter permanence are related to a higher incidence of bloodstream infections. It has been observed that low rates of catheter-related infections, i.e., close to zero, are already a reality in health institutions in developed countries, since they use infection surveillance and control programs.

Full Text Available 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.

A successful retrieval of a detached segment of a CVP catheter by percutaneous right transfemoral venous route, using a Dotter intravascular retriever basket, is reported. The procedure was monitored under fluoroscopy. Only local anaesthesia, which was infiltrated around the puncture site, was given to the patient. No significant complication was encountered. Successful retrieval of the detached catheter fragment by percutaneous means obviates the need for thoracotomy.

Removal of blunt esophageal foreign bodies using Foley catheter under a fluoroscopic guidance is a well recognized procedure. However, since this procedure is rather cumbersome and uncomfortable to the patient, the authors tried to find an easier and more convenient modified technique. For 10 patients with esophageal foreign body, we tried the method to the patient who is lying in the right lateral decubitus position and 3 assistants hold head, arms, trunk and legs of the patient without tilting the table and without using immobilizer. Foley catheter is inserted through nostril, nasal cavity and pharynx to esophagus. in order to identify the Foley catheter in esophagus, 0.025 inch short wire was inserted in the Foley catheter. The balloon of a Foley catheter was inflated by 10 cc of air, and the syringe was kept attached to the Foley catheter during the procedure. After passage of the foreign body through the upper esophageal sphinter, the balloon was deflated immediately and the foreign body was removed through the mouth. We successfully removed in removing all the blunt esophageal foreign body with ease. This modified method is also fast, safe and efficient

The lack of technical information from suppliers and from the literature, a wide variety of features and the absence of medical device reference document explain the difficulty for medical and pharmaceutical staffs to choose a central venous catheter (CVC). The aim of this study was to establish the specifications to choose a CVC according to the clinician needs. An analysis of suppliers' technical documentation and a literature review was performed to identify criteria and to collect them in a questionnaire to conduct semi-structured interviews between 1 pharmacist and 5 anaesthesiologists/intensivists. With these interviews, the technical criteria were classified according to their importance in 3 levels. Thirteen technical criteria were identified after reading the technical documents and the literature. Among them, 8 were classified as "essential criteria" (level I) by the physicians: J-shaped guide, one clamp on each way, identified lumen, radiopacity, graduation every centimeter by 5 to 20 cm from the distal extremity, a length of 15 to 25 cm, a single-lumen catheter with a 14 to 16G way and a three-lumen catheter with 14 to 18G way. Finally, three criteria were classified as "intermediate criteria" (level II) and two as "optional criteria" (level III). This collaborative approach allowed to reference new medical devices according to the clinicians needs. These CVC are a mean to respect guidelines for physicians and nurses and to secure the patient's care. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Antibiotic-impregnated central venous catheters (CVCs) decrease the incidence of infection in high-risk patients. However, use of these catheters carries the hypothetical risk of inducing antibiotic resistance. We hypothesized that routine use of minocycline and rifampin-impregnated catheters (MR-CVC) in a single intensive care unit (ICU) would change the resistance profile for Staphylococcus aureus. We reviewed antibiotic susceptibilities of S. aureus isolates obtained from blood cultures in a large urban teaching hospital from 2002-2015. Resistance patterns were compared before and after implementation of MR-CVC use in the surgical ICU (SICU) in August 2006. We also compared resistance patterns of S. aureus obtained in other ICUs and in non-ICU patients, in whom MR-CVCs were not used. Data for rifampin, oxacillin, and clindamycin were available for 9,703 cultures; tetracycline resistance data were available for 4,627 cultures. After implementation of MR-CVC use in the SICU, rifampin resistance remained unchanged, with rates the same as in other ICU and non-ICU populations (3%). After six years of use of MR-CVCs in the SICU, the rate of tetracycline resistance was unchanged in all facilities (1%-3%). The use of MR-CVCs was not associated with any change in S. aureus oxacillin-resistance rates in the SICU (66% vs. 60%). However, there was a significant decrease in S. aureus clindamycin resistance (59% vs. 34%; p resistance of S. aureus isolates to rifampin or tetracyclines.

Full Text Available Background. Central venous catheter (CVC related infection is associated with significant increases in morbidity, mortality, and health care cost.This local surveillance study was carry out to monitor the frequency of occurrence of CVC-related blood stream infections. Materials and methods. During the period January – December 2005, 226 CVC specimens were analyzed (quantitative method and microrganism identification from positive samples was performed by Vitek II. In 53 patients it was possible to compare quantitative results with those obtained from blood cultures. Results. Positive CVC samples were 125 (55% and 130 microrganisms were isolated: 109 Gram-positives (84%, 4 Gram-negatives (3%, and 17 mycetes (13%. Among pathogens collected simultaneously from CVC and blood samples, the most frequently isolated were Staphylococcus spp. (30% coagulase-negative staphylococci and 20%. S. aureus and Candida spp. (45%. In the group of patients that presented positive CVC and negative blood samples the most frequently recovered microrganisms were staphylococci. Many isolates (33% were polymicrobial. Conclusions. Catheter-related infections occurred in those patients who presented the same pathogen in both CVC and blood cultures. These infections were principally caused by staphylococci and Candida spp. On the contrary, a possible CVC contamination could be suspected when positive CVC and negative blood cultures were found.

BACKGROUND There is little data comparing catheter-directed thrombolysis (CDT) via small saphenous veins vs. systematic thrombolysis on complications and efficacy in acute deep venous thrombosis patients. The aim of our study was to compare the efficacy and safety of CDT via the small saphenous veins with systematic thrombolysis for patients with acute deep venous thrombosis (DVT). MATERIAL AND METHODS Sixty-six patients with acute DVT admitted from June 2012 to December 2013 were divided into 2 groups: 27 patients received systemic thrombolysis (ST group) and 39 patients received CDT via the small saphenous veins (CDT group). The thrombolysis efficiency, limb circumference differences, and complications such as post-thrombotic syndrome (PTS) in the 2 groups were recorded. RESULTS The angiograms demonstrated that all or part of the fresh thrombus was dissolved. There was a significant difference regarding thrombolysis efficiency between the CDT group and ST group (71.26% vs. 48.26%, P=0.001). In both groups the postoperative limb circumference changes were higher compared to the preoperative values. The differences between postoperative limb circumferences on postoperative days 7 and 14 were significantly higher in the CDT group than in the ST group (all Pdeep venous thrombosis.

Extensive deep venous thrombosis (DVT) during pregnancy is usually treated with anticoagulation alone, risking significant post-thrombotic syndrome (PTS) in young patients. Catheter-directed thrombolysis (CDT) and operative venous thrombectomy have been safely and effectively used in nonpregnant patients, demonstrating significant reduction in post-thrombotic morbidity. This report reviews short- and long-term outcomes of 13 patients with extensive DVT of pregnancy treated with a strategy of thrombus removal. From 1999 to 2013, 13 patients with iliofemoral DVT during pregnancy were offered CDT, pharmacomechanical thrombolysis (PMT), and/or venous thrombectomy. Gestational age ranged from 8 to 34 weeks. Fetal monitoring was performed throughout hospitalization. Radiation exposure was minimized with pelvic lead shields, focal fluoroscopy, and limited angiographic runs. Follow-up included objective vein evaluation using venous duplex and PTS assessment using the Villalta scale. CDT and/or PMT were used in 11 patients. Two patients underwent venous thrombectomy alone, and one patient had operative thrombectomy as an adjunct to CDT and PMT. Each patient had complete or near-complete thrombus resolution and rapid improvement in clinical symptoms. Eight of 11 having CDT or PMT underwent venoplasty and stenting of the involved iliac veins. Twelve of the 13 delivered healthy infants at term. One patient opted for termination of her pregnancy. Mean patient and gestational ages were 26 years and 26 weeks, respectively. Mean follow-up was 1.3 years, with only one recurrence. Duplex ultrasonography demonstrated patent veins in all but one patient and normal valve function in 10 patients. Eleven patients had Villalta scores thrombus removal, resulting in a patent venous system, normal valve function in many, prevention of PTS, and reduction in recurrence. Copyright © 2014.

Peripheral venous access in elderly, hospitalized patients is often challenging. The usual alternative is insertion of a central venous catheter, with associated risk for complications. The purpose of this investigation was to determine the relative incidence of phlebitis secondary to lower as compared to upper extremity intravenous catheters (IVCs) and associated risk factors. A non-randomized, observational, cohort-controlled study was carried out. Consecutive patients receiving a lower extremity IVC were enrolled and compared with patients receiving an upper extremity IVC. Patients were followed from insertion until removal of the IVC. The major endpoint was phlebitis. The incidence of phlebitis secondary to upper extremity IVCs was 3/50 (6 %) compared to 5/53 (9.4 %) in lower extremity IVCs (χ(2) Yates = 0.08, p = 0.776). Age, gender, obesity, diabetes mellitus, site (arm versus leg, left versus right), and size of needle were not found to be risk factors for phlebitis according to univariate analysis. None of the patients developed bloodstream infection. In elderly patients with poor venous access, lower extremity IVCs are a reasonable and low-risk alternative to central venous catheters.

Neonates with congenital diaphragmatic hernia (CDH) often require placement of lines and tubes for supportive therapy. The resulting altered anatomy can result in diagnostic errors when interpreting the location of support lines and tubes such as UVCs (umbilical venous catheters). The purpose of this study was to evaluate the effect of CDH on UVC position and to evaluate the accuracy at which radiologists describe the position on chest radiographs. During a 5-year period, 406 chest radiographs performed within 7 days of birth in infants with congenital diaphragmatic hernia were identified and reviewed for the following data: presence of UVC, location of catheter tip (cavoatrial junction, intracardiac, intrahepatic or umbilical vein), and location of CDH (right or left). The radiologic report of the UVC tip location for each case was then reviewed individually to determine the adequacy of interpretation. Inadequate reports were classified as incorrect (the wrong location of the catheter tip was reported), no mention (the location of the catheter tip was in a suboptimal location but not mentioned), and not specified (the precise location of the catheter tip was not clearly stated in the report when the tip was in a suboptimal location). A total of 60 infants were identified as having CDH (56 on the left, 4 on the right). The most common location for an incorrectly placed UVC was the contralateral chest, accounting for 26.7% (16/60) of the infants, followed by an abdominal intrahepatic location (16.7%) and the umbilical vein (8.3%). Thirty percent (120/406) of the chest radiograph reports were found to be inadequate regarding the interpretation of the location of the catheter tip. The majority of the inadequate reports (48/406, 11.8%) did not specify when the catheter tip was in a suboptimal location. In 37 reports (9.1%), the location of the catheter tip was reported incorrectly, and no mention of the catheter location was made in 35 reports (8.6%). The location of

To assess the CT findings of acute deep venous thrombosis (DVT) in a lower extremity prior to catheter-directed thrombolysis, and to evaluate their relevance to the patency of an iliac venous stent placed with the help of CT after catheter-directed thrombolysis of DVT. Fourteen patients [M:F=3:11; age, 33-68 (mean, 50.1) years] with acute symptomatic DVD of a lower extremity underwent CT before and after catheter-directed thrombolysis using an iliac venous stent. The mean duration of clinical symptoms was 5.0 (range, 1-14 days. The CT findings prior to thrombolysis were evaluated in terms of their anatomic cause and the extent of the thrombus, and in all patients, the patency of the iliac venous stent was assessed at CT performed during a follow-up period lasting 6-31 (mean, 18.9) months. All patients were assigned to the patent stent group (n=9) or the occluded stent group (n=5). In the former, the anatomic cause of patency included typical iliac vein compression (May-Thurner syndrome) (n=9), and a relatively short segmental thrombus occurring between the common iliac and the popliteal vein (n=8). Thrombi occurred in the iliac vein (n=3), between the common iliac and the femoral vein (n=3), and between the common iliac and the popliteal vein (n=2). In one case, a relatively long segmental thrombus occurred between the common iliac vein and the calf vein. In the occluded stent group, anatomic causes included atypical iliac vein compression (n=3) and a relatively long segmental thrombus between the common iliac and the calf vein (n=4). Typical iliac vein compression (May-Thurner syndrome) occurred in two cases, and a relatively short segmental thrombus between the external iliac and the common femoral vein in one. Factors which can affect the patency of an iliac venous stent positioned after catheter-directed thrombolysis are the anatomic cause of the stenosis, and the extent of a thrombus revealed at CT of acute DVT and occurring in a lower extremity prior to

To reduce the incidence of urinary tract infection, Surgical Care Improvement Project 9 mandates the removal of urinary catheters within 48 hours postoperatively. In patients with thoracic epidural anesthesia, we sought to determine the rate of catheter reinsertion, the complications of reinsertion, and the factors associated with reinsertion. We conducted a prospective observational study of consecutive patients undergoing major pulmonary or esophageal resection with thoracic epidural analgesia over a 2-year period. As per Surgical Care Improvement Project 9, all urinary catheters were removed within 48 hours postoperatively. Excluded were patients with chronic indwelling catheter, patients with urostomy, and patients requiring continued strict urine output monitoring. Multivariable logistic regression analysis was used to identify independent risk factors for urinary catheter reinsertion. Thirteen patients met exclusion criteria. Of the 275 patients evaluated, 60 (21.8%) required reinsertion of urinary catheter. There was no difference in the urinary tract infection rate between patients requiring reinsertion (1/60 [1.7%]) versus patients not requiring reinsertion (1/215 [0.5%], P = .389). Urethral trauma during reinsertion was seen in 1 of 60 patients (1.7%). After reinsertion, discharge with urinary catheter was required in 4 of 60 patients (6.7%). Multivariable logistic regression analysis found esophagectomy, lower body mass index, and benign prostatic hypertrophy to be independent risk factors associated with catheter reinsertion after early removal in the presence of thoracic epidural analgesia. When applying Surgical Care Improvement Project 9 to patients undergoing thoracic procedures with thoracic epidural analgesia, consideration to delayed removal of urinary catheter may be warranted in patients with multiple risk factors for reinsertion.

The use of catheter hub decontamination protocols is a common practice to reduce central line-associated bloodstream infections. However, few data exist on the most effective disinfection procedure prior to hub access accounting for human factors and time-dependent practices in real time in the clinical setting. An observational design with a multimodal intervention was used in this study in a neonatal intensive care unit. Direct observations on nurse compliance of scrub times with decontamination when accessing of venous catheter and feeding tube hubs were conducted during 3 phases: (1) baseline period prior to any interventions; (2) during an educational intervention phase; and (3) during a timer intervention period when using a timing device, either an actual timer or music button. Overall, both education and the timing device interventions increased the mean scrub time ± SD of venous catheter hubs. Mean baseline scrub times of 10 ± 5 seconds were lower compared with 23 ± 12 seconds after educational intervention (P music button use (P observed with scrub times of feeding tubes. Time-based infection control measures, such as scrubbing the hub, must be implemented with aids that qualify specific times to account for human factors, to ensure adherence to time-dependent measures aimed at decreasing nosocomial infections.

Priscila Costa

2015-06-01

Full Text Available OBJECTIVE: to develop a risk score for unplanned removal of peripherally inserted central catheter in newborns.METHOD: prospective cohort study conducted in a neonatal intensive care unit with newborn babies who underwent 524 catheter insertions. The clinical characteristics of the newborn, catheter insertion and intravenous therapy were tested as risk factors for the unplanned removal of catheters using bivariate analysis. The risk score was developed using logistic regression. Accuracy was internally validated based on the area under the Receiver Operating Characteristic curve.RESULTS: the risk score was made up of the following risk factors: transient metabolic disorders; previous insertion of catheter; use of a polyurethane double-lumen catheter; infusion of multiple intravenous solutions through a single-lumen catheter; and tip in a noncentral position. Newborns were classified into three categories of risk of unplanned removal: low (0 to 3 points, moderate (4 to 8 points, and high (≥ 9 points. Accuracy was 0.76.CONCLUSION: the adoption of evidence-based preventative strategies based on the classification and risk factors faced by the newborn is recommended to minimize the occurrence of unplanned removals.

Full Text Available Traditional recommendations suggest placement of a subclavian central venous catheter (CVC ipsilateral to a known pneumothorax to minimize risk of bilateral pneumothorax. We present the case of a 65-year-old male with a right hemopneumothorax who was found to have intrathoracic placement of his right subclavian CVC at thoracotomy despite successful aspiration of blood and transduction of central venous pressure (CVP. We thus recommend extreme caution with the interpretation of CVC placement by blood aspiration and CVP measurement alone in patients with large volume ipsilateral hemothorax.

Pulmonary embolism (PE) is a potentially life-threatening complication of critical illness. In trauma and neurosurgical patients with contraindications to anticoagulation, inferior vena cava (IVC) filters have been used to prevent PE, but their associated long-term complication rates and difficulties associated with filter removal have limited their use. The Angel catheter is a temporary device, which combined an IVC filter with a triple-lumen central venous catheter (IVC filter-catheter) and is intended for bedside placement and removal when no longer indicated. This study presents data from a European Registry of 60 critically ill patients in whom the IVC filter-catheter was used to prevent PE. The patients were all at high risk of PE development or recurrence and had contraindications to anticoagulation. The primary end points of this study were to evaluate the safety (in particular, the presence of infectious or thrombotic events) and effectiveness (the numbers of PEs and averted PEs) of the IVC filter-catheter. The main diagnosis before catheter insertion was major trauma in 33 patients (55%), intracerebral hemorrhage or stroke in 9 (15%), a venous thromboembolic event in 9 (15%), and active bleeding in 6 (10%). The IVC filter-catheter was placed as prophylaxis in 51 patients (85%) and as treatment in the 9 patients (15%) with venous thromboembolic event. The devices were inserted at the bedside without fluoroscopic guidance in 54 patients (90%) and within a median of 4 days after hospital admission. They were left in place for a mean of 6 days (4-8 days). One patient developed a PE, without hemodynamic compromise; two PEs were averted. No serious adverse events were reported. Early bedside placement of an IVC filter-catheter is possible, and our results suggest that this is a safe, effective alternative to short-term PE prophylaxis for high-risk patients with contraindications to anticoagulation.

Purpose: Our purpose was to report the outcome of endovascular treatment with manual aspiration thrombectomy as the first-line thromboablative method for phlegmasia cerulea dolens. Methods: Between October 2006 and May 2010, seven consecutive patients (5 women, 2 men; age range, 31–80 years) with the diagnosis of phlegmasia cerulea dolens secondary to acute iliofemoral deep venous thrombosis had endovascular treatment with manual aspiration thrombectomy. Catheter-directed thrombolysis and stent placement were used as adjunctive procedures. Phlegmasia was left-sided in five and right-sided in two patients. Results: All patients had associated great saphenous vein thrombosis in addition to iliofemoral deep vein thrombosis (DVT). Aspiration thrombectomy completely removed the thrombus from the popliteal vein to the inferior vena cava (IVC) in all cases. Three patients with May-Thurner syndrome had stent placement in the left common iliac vein. Two patients had early recurrences. Repeated aspiration thrombectomy was unsuccessful in one patient. There were no complications related to the procedure. One patient who had been successfully treated died of sepsis and another patient who had unsuccessful repeated interventions had below-the-knee amputation. Overall, the clinical success and survival rates of patients in this study were 86%. On follow-up, three patients with successful treatment were asymptomatic with no deep venous insufficiency. One of these patients died during the 4-month follow-up period. Two patients had mild ankle swelling with deep venous insufficiency. Conclusions: Manual aspiration thrombectomy with adjunctive use of catheter-directed thrombolysis and stent placement is an effective endovascular treatment method with high clinical success and survival rates for phlegmasia cerulean dolens.

PurposeImplanted venous access devices (IVADs) are often used in patients who require long-term intravenous drug administration. The most common causes of device dysfunction include occlusion by fibrin sheath and/or catheter adherence to the vessel wall. We present percutaneous endovascular salvage techniques to restore function in occluded catheters. The aim of this study was to evaluate the feasibility, safety, and efficacy of these techniques.Methods and MaterialsThrough a femoral or brachial venous access, a snare is used to remove fibrin sheath around the IVAD catheter tip. If device dysfunction is caused by catheter adherences to the vessel wall, a new “mechanical adhesiolysis” maneuver was performed. IVAD salvage procedures performed between 2005 and 2013 were analyzed. Data included clinical background, catheter tip position, success rate, recurrence, and rate of complication.ResultsEighty-eight salvage procedures were performed in 80 patients, mostly women (52.5 %), with a mean age of 54 years. Only a minority (17.5 %) of evaluated catheters were located at an optimal position (i.e., cavoatrial junction ±1 cm). Mechanical adhesiolysis or other additional maneuvers were used in 21 cases (24 %). Overall technical success rate was 93.2 %. Malposition and/or vessel wall adherences were the main cause of technical failure. No complications were noted.ConclusionThese IVAD salvage techniques are safe and efficient. When a catheter is adherent to the vessel wall, mechanical adhesiolysis maneuvers allow catheter mobilization and a greater success rate with no additional risk. In patients who still require long-term use of their IVAD, these procedures can be performed safely to avoid catheter replacement

Deep venous thrombosis and postthrombotic syndrome: invasive management.

Science.gov (United States)

Comerota, A J

2015-03-01

Invasive management of postthrombotic syndrome encompasses the two ends of the deep vein thrombosis spectrum, patients with acute iliofemoral deep vein thrombosis and those with chronic postthrombotic iliofemoral venous obstruction. Of all patients with acute deep vein thrombosis, those with involvement of the iliofemoral segments have the most severe chronic postthrombotic morbidity. Catheter-based techniques now permit percutaneous treatment to eliminate thrombus, restore patency, potentially maintain valvular function, and improve quality of life. Randomized trial data support an initial treatment strategy of thrombus removal. Failure to eliminate acute thrombus from the iliofemoral system leads to chronic postthrombotic obstruction of venous outflow. Debilitating chronic postthrombotic symptoms of the long-standing obstruction of venous outflow can be reduced by restoring unobstructed venous drainage from the profunda femoris vein to the vena cava. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Neonatal sepsis is the most frequent health care-associated infection in neonatal units. This study aimed to analyze articles on the clinical usefulness of catheter-drawn blood samples and catheter tip cultures for the diagnosis of intravascular catheter-related bloodstream infection (CRBSI) in neonates. A systematic search was performed for studies published from 1987-2017, without language restriction. Observational studies carried out in neonates with CRBSI diagnosed using catheter-drawn blood samples or catheter tip cultures were included. A total of 412 articles were identified in the databases and 10 articles were included. The 7 studies that evaluated central venous catheter tip cultures and cultures of catheter fragments presented sensitivities ranging from 58.5%-100% and specificities ranging from 60%-95.7%. Three studies that evaluated catheter-drawn blood cultures, paired with peripheral blood cultures, reported sensitivity and specificity of 94% and 71% when evaluated for the differential time to positivity. When quantitative evaluation was performed, the sensitivity and specificity were 80% and 99.4%. Most of the studies analyzed cultures from the central venous catheter tip and catheter fragments for the diagnosis of CRBSI in neonatal populations. The results of this review suggest that the analysis of the catheter-drawn blood samples and catheter tip cultures, paired with peripheral blood cultures, are efficient methods for the diagnosis of CRBSI in neonates.

To assess the utility of maintaining and analyzing a quality-management database while investigating a subjectively perceived increase in the incidence of tunneled catheter and port dysfunction in a cohort of oncology outpatients. All 152 patients undergoing lytic therapy (2-4 mg alteplase) of a malfunctioning indwelling central venous catheter (CVC) from January through June 2004 at a single cancer center in the United States were included in a quality-management database. Patients were categorized by time to device failure and the initial method of catheter placement (surgery vs interventional radiology). Data were analyzed after 3 months, and areas of possible improvement were identified and acted upon. Three months of follow-up data were then collected and similarly analyzed. In a 6-month period, 152 patients treated for catheter malfunction received a total of 276 doses of lytic therapy. A 3-month interim analysis revealed a disproportionately high rate (34%) of early catheter malfunction (ECM; <30 days from placement). Postplacement radiographs demonstrated suboptimal catheter positioning in 67% of these patients, all of whom had surgical catheter placement. There was a 50% absolute decrease in the number of patients presenting with catheter malfunction in the period from April through June (P < .001). Evaluation of postplacement radiographs in these patients demonstrated a 50% decrease in the incidence of suboptimal positioning (P < .05). Suboptimal positioning was likely responsible for some, but not all, cases of ECM. Maintenance of a quality-management database is a relatively simple intervention that can have a clear and important impact on the quality and cost of patient care.

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.

Interventional radiology in the provision and maintenance of long-term central venous access

Lyon, S.M.; Given, M.; Marshall, N.L.

2008-01-01

Establishing and maintaining venous access forms an increasing proportion of the workload in interventional radiology. Several patient groups require medium-term to long-term venous catheters for a variety of purposes, including chemotherapy, long-term antimicrobials, parenteral nutrition, short-term access for haemodialysis or exhausted haemodialysis. Often, these catheters are required for treatment and frequent blood testing, which can quickly exhaust the peripheral veins. Venous access devices include implantable catheters (ports), tunnelled catheters and peripherally inserted central catheters, which have different functions, advantages and limitations. Imaging-guided placement is the preferred method of insertion in many institutions because of higher success rates and radiologists are well suited to address catheter complications.

Full Text Available Elizabeth A Duffy, Kathryn N Nelson Department of Health Behavior and Biological Sciences, The University of Michigan School of Nursing, Ann Arbor, MI, USA Abstract: A central venous catheter (CVC is an indwelling catheter that provides permanent or temporary stable venous access for both acute and chronically ill pediatric patients. These catheters provide stable venous access that can be used for a variety of medical purposes including drawing blood, hemodynamic monitoring, infusion of intravenous medications, infusion of intravenous fluids, chemotherapy, blood products, and parenteral nutrition. Each day, nurses access and care for CVCs in infants, children, and adolescents; the precision of this care can prevent life-threatening complications. The purpose of this review and the case study is to highlight the importance and components of evidence-based nursing practice in pediatric CVC care. A historical perspective of CVC care is provided in conjunction with current national initiatives to improve patient outcomes for children with CVCs. Infection prevention, clinical practice guidelines, quality improvement, and evidence-based care bundles are discussed.

Accidental dislocation or removal is a well-known complication of external cerebrospinal fluid (CSF) drainage in daily clinical practice. At present, no data about the incidence of such complications are available in the scientific literature. SecurAcath (Interrad Medical, Plymouth, Minnesota, USA) is a subcutaneously anchored device recently adopted for securement of central venous catheters, known to be highly effective (and cost-effective) in reducing the risk of catheter dislodgement and/or accidental removal. We report our preliminary experience with the use of SecurAcath to secure CSF drainage, either ventricular or spinal, to the skin. SecurAcath was used in 29 consecutive patients (age range: 3 weeks-16 years, median age 6.3 years). In particular, the device was used for 25 ventricular catheters (a patient received 2 catheters in the same procedure for bilateral brain abscess) and 5 spinal drainages. Period in place ranged from 1-4 weeks (median 22 days). No complication related to the use of the device was observed, in particular there was no case of dislocation or accidental removal of the catheter. The removal procedure was extremely easy. The device has proven its utility also in 3 cases requiring an adjustment of the length of the catheter. In our experience, SecurAcath is a safe and effective device to secure CSF external catheters to the skin, with several relevant advantages: its placement and maintenance are easy; it may stay in place for the entire duration of the catheter; it allows a more complete antisepsis of the exit site, thus reducing local skin complications; it eliminates the risk of suture-related needlestick injuries.

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

Port-A-Cath devices are frequently used for long-term venous access. We postulate that long-term use predisposes them to getting stuck and retained in a central vein at the time of removal. We aim to report the incidence and outcome of this complication. Between January 2006 and July 2016, a retrospective review of all Port-A-Cath removals that were performed at our centre was conducted. At the time of removal, catheters that could not be removed from the vein were considered retained. During the study period, 107 children had 174 episodes of silicone Sitimplant (Vygon, Ecouen, France) Port-A-Cath insertions. These children required 135 removal episodes and there were 3 (2.2%) instances whereby the catheter fragment was retained. These episodes of retained catheters only occurred in children with factor VIII deficiency (4.1% incidence in this cohort). For each episode of catheter insertion and removal, the catheters had been left in situ for a mean duration of 43 months in children with factor deficiency and no retained fragments, and the mean duration was 91 months in children with factor deficiency and retained catheter fragments (p = 0.0011). Port-A-Caths that are retained after attempted removal is a complication encountered predominantly in catheters that have been in use for a prolonged duration. Furthermore, factor replacement therapy in haemophiliacs may be a risk factor for this complication.

Totally implantable venous access port plays a crucial role in the treatment of patients in oncology. However, its use can result sporadically in catheter fracture with catheter tip embolization into pulmonary arteries. We report this unusual but potentially serious complication in four patients. In these patients, the port had been inserted percutaneously into the subclavian vein using the infra-clavicular approach. This side effect occurred late in three patients. In all patients, the catheter fracture was asymptomatic or pauci-symptomatic and was caused by the pinch-off syndrome. The retrieval of the embolized fragments was successfully performed by transcatheter procedure in the cardiac catheterisation laboratory. We reviewed the literature and the newest guidelines and recommendations to detail the clinico-radiological features, the possible causes of this complication and discussed means to recognize, manage and prevent it.

The bowed catheter sign: a risk for pericardial tamponade

Energy Technology Data Exchange (ETDEWEB)

Towbin, Richard [Phoenix Children' s Hospital, Department of Radiology, Phoenix, AZ (United States)

2008-03-15

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

In this paper, we further examine the risks and benefits of utilizing an indwelling peritoneal catheter to remove large-volume ascites over a 72-h period while maintaining intravascular volume and preventing renal failure. Methods: We retrospectively reviewed charts and identified 36 consecutive patients undergoing continuous large-volume paracentesis with an indwelling peritoneal catheter. At the time of drain placement, no patients had signs or laboratory parameters suggestive of spontaneous bacterial peritonitis. The patients underwent ascitic fluid removal through an indwelling peritoneal catheter and were supported with scheduled albumin throughout the duration. The catheter was used to remove up to 3 L every 8 h for a maximum of 72 h. Regular laboratory and ascitic fluid testing was performed. All patients had a clinical follow-up within 3 months after the drain placement. Results: An average of 16.5 L was removed over the 72-h time frame of indwelling peritoneal catheter maintenance. The albumin infusion utilized correlated to 12 mg/L removed. The average creatinine trend improved in a statistically significant manner from 1.37 on the day of admission to 1.21 on the day of drain removal. No patients developed renal failure during the hospital course. There were no documented episodes of neutrocytic ascites or bacterial peritonitis throughout the study review. Conclusion: Large-volume peritoneal drainage with an indwelling peritoneal catheter is safe and effective for patients with tense ascites. Concomitant albumin infusion allows for maintenance of renal function, and no increase in infectious complications was noted.

A young male underwent decompressive craniotomy for an intracerebral bleed. A right-sided subclavian central venous catheter was placed in the operating room after induction of anesthesia. Postoperatively, he was shifted to Intensive Care Unit (ICU) for mechanical ventilation due to low Glasgow coma scale. He had an episode of severe agitation and straining on the tracheal tube in the evening same day. On the 2 nd postoperative day in ICU, his airway pressures were high, and chest X-ray revealed massive pleural effusion on right side. Under ultrasound guidance, 1400 milky white fluid was aspirated. It was sent for analysis (triglycerides) that confirmed chyle and hence, chylothorax was made as diagnosis. A duplex scan was done which ruled out thrombosis in subclavian vein. The catheter had normal pressure tracing with free aspiration of blood from all ports. Enteral feeding was continued as it is a controversial matter in the literature and he was monitored clinically and radiologically.

Anticoagulation with heparin has been the standard management therapy of deep vein thrombosis during pregnancy. Pregnancy is generally considered as a contraindication for thrombolysis. However, anticoagulation therapy alone does not protect the limbs from post-thrombotic syndrome and venous valve insufficiency. Catheter-directed thrombolysis, combined with angioplasty and stenting, can remove the thrombus and restore patency of the veins, resulting in prevention of post-thrombotic syndrome and valve insufficiency. We report successful catheter-directed thrombolysis and stenting in two early gestation patients with a deep vein thrombosis of the left lower extremity

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.)

A high level of maintenance is required to preserve patency, although this approach provides remarkably durable access for patients who have otherwise exhausted access options.

Primary thromboprophylaxis for cancer patients with central venous catheters--a reappraisal of the evidence.

Venous thromboembolism (VTE) is responsible for an estimated 25 000 deaths per annum in UK hospital practice. It is well established that many of these deaths could be prevented through the use of appropriate thromboprophylaxis. This issue is of particular relevance in oncology practice, where the risks of VTE and bleeding are both significantly higher than those observed in general medical patients. Cancer patients with in-dwelling central venous catheters (CVCs) are at particularly high risk of developing thrombotic complications. However, the literature has produced conflicting conclusions regarding the efficacy of using routine primary thromboprophylaxis in these patients. Indeed such is the level of confusion around this topic, that the most recent version of the American College of Chest Physicians (ACCP) guidelines published in 2004 actually reversed their previous recommendation (published in 2001). Nevertheless, minidose warfarin continues to be routinely used in many oncology centres in the UK. In this article, we have performed a systematic review of the published literature regarding the efficacy and the risks, associated with using thromboprophylaxis (either minidose warfarin or low-dose LMWH) in cancer patients with CVC. On the basis of this evidence, we conclude that there is no proven role for using such thromboprophylaxis. However, asymptomatic CVC-related venous thrombosis remains common, and further more highly powered studies of better design are needed in order to define whether specific subgroups of cancer patients might benefit from receiving thromboprophylaxis.

The objective was to examine the success and immediate complication rates in a large series of radiologically placed tunneled central venous catheters. We prospectively recorded the success and immediate complication rates in 880 consecutive radiologically placed tunneled central venous catheters. We also recorded the indication for placement, the success of placement, the number of passes required, and whether a double- or single-wall puncture occurred. Hemodialysis was the most common indication for long-term venous access. Venous access was successful in all patients, and catheter placement was successful in 99.4% of patients, with only five failed placements. All patients in whom placement was initially unsuccessful underwent successful placement the same day. All catheters were placed using real-time sonographic guidance. Most were placed in an internal jugular vein, with 87.4% requiring only a single needle pass. The immediate complication rate was only 4.0%, and no major complications occurred. To our knowledge, this series is the largest for which the immediate complication and success rates for radiologically placed central venous catheters have been reported. Our results suggest that radiologic placement of tunneled central venous catheters is a safe and effective alternative to surgery.

The impact of the alternative sigma factor sigma B (SigB) on pathogenesis of Staphylococcus aureus is not conclusively clarified. In this study, a central venous catheter (CVC) related model of multiorgan infection was used to investigate the role of SigB for the pathogenesis of S. aureus infections and biofilm formation in vivo. Analysis of two SigB-positive wild-type strains and their isogenic mutants revealed uniformly that the wild-type was significantly more virulent than the SigB-deficient mutant. The observed difference in virulence was apparently not linked to the capability of the strains to form biofilms in vivo since wild-type and mutant strains were able to produce biofilm layers inside of the catheter. The data strongly indicate that the alternative sigma factor SigB plays a role in CVC-associated infections caused by S. aureus.

Although long-term indwelling central venous catheters (CVCs) may lead to pulmonary embolism (PE) and loss of the CVC, there is lack of consensus on management of CVC-related thrombosis (CRT) in cancer patients and heterogeneity in clinical practices worldwide. To establish common international Good Clinical Practices Guidelines (GCPG) for the management of CRT in cancer patients. An international working group of experts was set up to develop GCPG according to an evidence-based medicine approach, using the GRADE system. For the treatment of established CRT in cancer patients, we found no prospective randomized studies, two non-randomized prospective studies and one retrospective study examining the efficacy and safety of low-molecular-weight heparin (LMWH) plus vitamin K antagonists (VKAs). One retrospective study evaluated the benefit of CVC removal and two small retrospective studies were on thrombolytic drugs. For the treatment of symptomatic CRT, anticoagulant treatment (AC) is recommended for a minimum of 3 months; in this setting, LMWHs are suggested. VKAs can also be used, in the absence of direct comparisons of these two types of anticoagulants in this setting [Guidance]. The CVC can be kept in place if it is functional, well-positioned and non-infected and there is good resolution under close surveillance; whether the CVC is kept or removed, no standard approach in terms of AC duration has been established [Guidance]. For the prophylaxis of CRT in cancer patients, we found six randomized studies investigating the efficacy and safety of VKA vs. placebo or no treatment, one on the efficacy and safety of unfractionnated heparin, six on the value of LMWH, one double-blind randomized and one non randomized study on thrombolytic drugs and six meta-analyses of AC and CVC thromboprophylaxis.

Peripherally inserted central catheters (PICCs) are associated with an increased risk of venous thromboembolism. However, the size of this risk relative to that associated with other central venous catheters (CVCs) is unknown. We did a systematic review and meta-analysis to compare the risk of venous thromboembolism associated with PICCs versus that associated with other CVCs. We searched several databases, including Medline, Embase, Biosis, Cochrane Central Register of Controlled Trials, Conference Papers Index, and Scopus. Additional studies were identified through hand searches of bibliographies and internet searches, and we contacted study authors to obtain unpublished data. All human studies published in full text, abstract, or poster form were eligible for inclusion. All studies were of adult patients aged at least 18 years who underwent insertion of a PICC. Studies were assessed with the Newcastle-Ottawa risk of bias scale. In studies without a comparison group, the pooled frequency of venous thromboembolism was calculated for patients receiving PICCs. In studies comparing PICCs with other CVCs, summary odds ratios (ORs) were calculated with a random effects meta-analysis. Of the 533 citations identified, 64 studies (12 with a comparison group and 52 without) including 29 503 patients met the eligibility criteria. In the non-comparison studies, the weighted frequency of PICC-related deep vein thrombosis was highest in patients who were critically ill (13·91%, 95% CI 7·68-20·14) and those with cancer (6·67%, 4·69-8·64). Our meta-analysis of 11 studies comparing the risk of deep vein thrombosis related to PICCs with that related to CVCs showed that PICCs were associated with an increased risk of deep vein thrombosis (OR 2·55, 1·54-4·23, p<0·0001) but not pulmonary embolism (no events). With the baseline PICC-related deep vein thrombosis rate of 2·7% and pooled OR of 2·55, the number needed to harm relative to CVCs was 26 (95% CI 13-71). PICCs are

Efficacy and safety of using L-cysteine as a catheter-clearing agent for nonthrombotic occlusions of central venous catheters in children.

Critically ill pediatric patients, especially in the intensive care unit, receive multiple medications and have a higher risk of central venous catheter (CVC) occlusion. If an occlusion occurs immediately after the administration of multiple medications or incompatible medications, either an acidic solution such as 0.1 N hydrochloric acid (HCl) or a basic solution of 1 mEq/mL sodium bicarbonate or 0.1 N sodium hydroxide can be used. However, compounding and storing of 0.1 N HCl has become more complex due to USP guidelines for sterile compounding, and an alternative is needed. We report a series of cases in which L-cysteine was used instead of HCl to clear CVCs occluded due to administration of multiple medications. L-cysteine is a commercially available, sterile solution with a pH of 1–2.5. CVC occlusion was resolved in 10 of the 16 episodes in 13 patients. Two of the 16 occlusions were phenytoin related and would not have responded. An L-cysteine dose of 50 mg was used during 10 of the 16 episodes, 100 mg during 5 episodes, and 25 mg during 1 episode. A correlation between catheter clearance and dose was not observed. Occlusion resolution due to L-cysteine was not correlated to the prior use of tissue plasminogen activator. Metabolic acidosis, adverse effects, or damage to the catheters due to L-cysteine were not observed. On the basis of this limited experience, we propose L-cysteine as an effective alternative to 0.1 N HCl for clearing CVC occlusions caused by drugs with an acidic pKa.

Hickman catheter inserter has previously been predominantly accomplished surgically by means of venous cutdown or percutaneous placement in the operating room. The authors describe their method and results for 55 consecutive percutaneous placements of Hickman catheters in the interventional radiology suite. Complication rates were comparable to those for surgical techniques. Radiologic placement resulted in increased convenience, decreased time and cost of insertion, and super fluoroscopic control of catheter placement and any special manipulations. Modern angiographic materials provide safer access to the subclavian vein than traditional methods. The authors conclude that radiologic placement of Hickman catheters offers significant advantages over traditional surgical placement

The use of intravascular catheters is often complicated by phlebitis, which is associated with increased morbidity and extended duration of hospitalization. We conducted a study to investigate the impact of needleless intravenous access devices on the rate of phlebitis in peripheral venous catheters (PVCs). We prospectively recruited patients in 2 phases. The first group was treated with a regular cap, and the second group was treated with a needleless connector. The incidence of catheter-related phlebitis (CRP) was recorded as the primary end point. A total of 620 PVCs using regular caps were inserted into 340 patients and CRP rates were recorded. In the second phase of the study, 169 PVCs using needleless connectors were inserted into 135 patients. In the group treated with the regular cap, the CRP rate was 60% compared with 7% in the group treated with the needleless cap (P phlebitis had a statistically significant longer mean hospitalization period (P <.001), as were patients in the regular cap group (P <.01). The use of needleless connectors was found to be associated with a significant reduction of CRP in peripheral veins in a surgery department setting. The decreased morbidity resulted in a lower number of catheter replacements and duration of hospitalization. Copyright © 2017 Association for Professionals in Infection Control and Epidemiology, Inc.

Convective Leakage Makes Heparin Locking of Central Venous Catheters Ineffective Within Seconds: Experimental Measurements in a Model Superior Vena Cava.

Central venous catheters (CVCs), placed in the superior vena cava (SVC) for hemodialysis or chemotherapy, are routinely filled while not in use with heparin, an anticoagulant, to maintain patency and prevent thrombus formation at the catheter tip. The heparin-locking procedure, however, places the patient at risk for systemic bleeding, as heparin is known to leak from the catheter into the blood stream. We provide evidence from detailed in vitro experiments that shows the driving mechanism behind heparin leakage to be convective-diffusive transport due to the pulsatile flow surrounding the catheter. This novel mechanism is supported by experimental planar laser-induced fluorescence (PLIF) and particle image velocimetry (PIV) measurements of flow velocity and heparin transport from a CVC placed inside a model SVC inside a pulsatile flow loop. The results predict an initial, fast (<10 s), convection-dominated phase that rapidly depletes the concentration of heparin in the near-tip region, the region of the catheter with side holes. This is followed by a slow, diffusion-limited phase inside the catheter lumen, where the concentration is still high, that is insufficient at replenishing the lost heparin concentration in the near-tip region. The results presented here, which are consistent with previous in vivo estimates of 24 hour leakage rates, predict that the concentration of heparin in the near-tip region is essentially zero for the majority of the interdialytic phase, rendering the heparin locking procedure ineffective.

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

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.

Removing Nasal Packing in Epistaxis: What to Do in the Case of an Undeflatable Foley Catheter Balloon

Directory of Open Access Journals (Sweden)

Gaspar-Sobrinho, Fernando Pena

2014-01-01

Full Text Available Introduction Undeflatable Foley catheter balloons adapted for use as nasal packing in epistaxis represent a possible complication. Case Reports We report on three cases in which Foley catheter balloons adapted for use as posterior nasal packing in epistaxis failed to deflate. In one patient, deflation was achieved by simply using the fingertips to massage the segment of the catheter collapsed by the fixation device. In the second case, the Foley balloon was removed by the oral route after sectioning the catheter. In the third patient, the Foley catheter was successfully deflated after sectioning. Discussion The probable causes of the undeflatable balloons in these cases were a blockage or lumen collapse of the balloon or a malfunction in the valve system. Although no definitive method has been established for dealing with this complication, the options proposed are the following: manipulation to restore the permeability of the segment of the catheter collapsed by the fixation device, if this is the case; sectioning the catheter or inserting a stiletto catheter; bursting the balloon; or removing it by the oral route. The latter option is apparently the most appropriate for the otolaryngologist in cases unrelated to simple collapse caused by the fixation device.

Some patients with refractory peritoneal dialysis-related peritonitis continue to develop intra-abdominal complications despite removal of the peritoneal catheter. Repeated percutaneous drainage or open laparotomy is often required, and mortality is not uncommon. The benefits of pelvic drainage placement during catheter removal in decreasing these complications and interventions remain unproven. Forty-six patients with refractory peritonitis who underwent removal of a Tenckhoff catheter between 1991 and 2013 were reviewed retrospectively. Twelve patients had pelvic drainage using closed active suction devices during catheter removal (drainage group). The remaining 34 patients underwent catheter removal without drainage (non-drainage group). The outcomes measured were the development of intra-abdominal complications and the requirement for repeated percutaneous drainage or open laparotomy within 90 days after the catheter removal. Baseline characteristics were similar with the exception of a higher median number of previous peritonitis episodes in the drainage group compared with the non-drainage group (2 vs 0, P = 0.02). During the follow-up period, intra-abdominal complications occurred in 15 (44%) of 34 patients in the non-drainage group, compared with one (8%) of 12 patients in the drainage group (P = 0.03). Twelve (35%) patients in the non-drainage group required repeated percutaneous drainage or open laparotomy for management, compared with zero (0%) patients in the drainage group (P = 0.02). Drain tubes were removed at a median of 6 days (inter-quartile range: 5-10) without complications. In the management of refractory peritonitis, pelvic drainage during removal of dialysis catheter decreases the risk of subsequent intra-abdominal complications and invasive interventions. © 2015 Asian Pacific Society of Nephrology.

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

ENDOVASCULAR TREATMENT FOR DISORDERS OF THE VENOUS SYSTEM

Full Text Available The annual rate of deep vein thrombosis in general population is from 5 to 9 cases per 10 000, whereas for venous thromboembolism (deep vein thrombosis and pulmonary embolism taken together amounts to 14 cases per 10 000. To improve longterm results of therapy for thrombosis of deep veins of the lower extremities, it is important to restore venous function and outflow. Anticoagulant therapy with low weight or non-fractionated heparin preparations remains the most widely used method of management. However, total or partial thrombosis resolution under anticoagulant treatment is achieved only in 4 and 14% of cases, respectively. Thrombolysis allows for early resorption of the thrombus by means of a minimally invasive procedure with lower risk of complication. After the venous flow is restored, the aim of treatment is to prevent damage to the venous valves, venous hypertension and repeated thrombosis with development of the post-thrombotic syndrome. Compared to anticoagulation, systemic thrombolysis has the benefit of more rapid clot resorption and less damage to the venous valve. One of its serious limitations is a high bleeding risk related to higher doses of the drug administered through a peripheral vein catheter. Therefore, selective intra-clot administration of thombolytics (direct catheter thrombolysis has been suggested as an alternative. For more effective therapy with the use of lower doses of thrombolytics, the so called pharmaco-mechanical thrombectomy has been developed. Venous stenosis hindering the venous outflow is frequently seen after direct catheter or pharmaco-mechanical thrombolysis. Angioplasty with stent placement is recommended in the cases with residual venous abnormality after successful thrombolysis and thrombectomy.

The standard technique of catheter closure of patent ductus arteriosus (PDA) may be associated with arterial complications particularly in small pediatric patients. The aim of this study was to evaluate whether catheter closure of PDA in small children using an exclusive venous approach is a safe and effective alternative to closure with the standard technique. One hundred-twelve patients, aged 2 to 24 months, were randomly assigned in a 1:1 ratio to catheter closure of PDA using the standard technique (group 1) and an exclusive venous approach (group 2), respectively. In group 2, the procedure was guided using hand injections of contrast media through the delivery sheath and 2-dimensional and color Doppler echocardiography. Group 1: the PDA diameter ranged from 2 to 5.5 mm and the device diameter ranged from 4 to 8 mm. The PDA occluders were permanently implanted in all patients. Five losses of the arterial pulses that were restored with intravenous infusion of heparin and recombinant tissue plasminogen activator (rtPA), and 4 groin hematomas were the main complications of the procedure. Group 2: the mean PDA diameter ranged from 2.5 to 6 mm and the device diameter ranged from 3 to 8 mm. The PDA occluders were permanently implanted in all but 2 patients. There were no complications. Complete echocardiographic closure of PDA at 1-month follow-up was observed in all 110 patients. Exclusive transvenous PDA occlusion is an effective and safe technique that prevents the arterial complications of the standard approach in small children. Copyright © 2016 Elsevier Inc.

Introduction: Renal transplantation is the treatment of choice in chronic renal failure patients. Objectives: The purpose of this study was to evaluate the impact of urinary catheter removal time on transplanted kidney size and incidence of asymptomatic bacteriuria and urinary tract infections (UTIs). Patients and Methods: This retrospective cohort study evaluated the clinical outcomes of 109 consecutive live donor renal transplant recipients from December 2011 to July 2014. Routine ultrasound examinations were performed on donor's kidney prior to operation and one month later. Kidney volume was calculated. UTI and bacteriuria were evaluated one month later. Patients were divided into two groups based on time of Foley catheter removal (before and after fifth day posttransplantation). Results: In this study 74 males (67.9%) and 35 females (32.1%) were evaluated. Sixty-six patients (57.92%) were in group 1. None of the patients with positive urine culture had UTI but bacteriuria occurred in all of them (21.1%). Bacteriuria time after transplantation and catheter removal was significantly later in group 1 and it was not different in female group but they were later in male group. The mean renal volume increase was positively correlated to renal transplant recipient and donor's age and donor's body mass index (BMI) ( P UTI but increases the probability of bacteria in men whose catheter was removed within 5 days after transplantation. We also found that the renal volume change is not associated with catheter removal time and bacteriuria.

Complications from central venous catheterization include infectious conditions, pneumothorax, hemothorax and venous thrombosis. Pericardial effusion with cardiac tamponade hardly occurs, and in infants is generally caused by umbilical catheterization. The authors describe the case of cardiac tamponade occurred in an infant during chest computed tomography with contrast infusion through a central venous catheter inserted into the right internal jugular vein.

Background: Contrast-induced acute kidney injury is a severe condition resulting from the use of radiology contrast in patients with predisposing factors. Hypothesis: We hypothesized that a novel system including a device containing polymer resin sorbent beads and a custom-made suctioning catheter could efficiently remove contrast from an in vitro novel model of circulatory system (MOCS) mimicking the cerebral circulation. Methods: A custom-made catheter was built and optimized for cerebral venous approach. The efficiency of a system made of a polymer resin sorbent beads column (CST 401, Cytosorbents) and this particular catheter was tested in the MOCS running a solution composed of 0.9% saline and radio-contrast. During two series of 18 cycles of first-pass experiments we assessed the catheter's suctioning efficiency and the system's ability to clear radio-contrast injected into the MOCS's cerebral arterial segment. We also assessed the functioning and reliability of the MOCS. Results: Mean suctioning efficiency of the catheter was 84% ± 24%. The polymer sorbent column contrast removal rate was initially 96% and gradually decreased with subsequent cycles in a linear fashion during an experiment lasting approximately 90 minutes. The MOCS had a reliability of 0.9946×min −1 where 1 × min −1 was the optimum value. Conclusion: A system including a polymer resin sorbent beads column and a custom-made suctioning catheter had an excellent initial efficiency in quickly removing contrast from an artificial MOCS mimicking the cerebral circulation. MOCS is an inexpensive and relatively reliable custom-made system that can be used for training or testing purposes

This study was designed to assess endovascular intervention for central venous cannulation in patients with vascular occlusion after previous catheterization. Patients referred for endovascular management of central venous occlusion during a 42-month period were identified from a regional endovascular database, providing prospective information on techniques and clinical outcome. Corresponding patient records, angiograms, and radiographic reports were analyzed retrospectively. Sixteen patients aged 48 years (range 0.5-76), including 11 females, were included. All patients but 1 had had multiple central venous catheters with a median total indwelling time of 37 months. Eleven patients cannulated for hemodialysis had had significantly fewer individual catheters inserted compared with 5 patients cannulated for nutritional support (mean 3.6 vs. 10.2, pvenous occlusions. Patients were subjected to recanalization (n=2), recanalization and percutaneous transluminal angioplasty (n=5), or stenting for vena cava superior syndrome (n=1) prior to catheter insertion. The remaining 8 patients were cannulated by avoiding the occluded route. Central venous occlusion occurs particularly in patients under hemodialysis and with a history of multiple central venous catheterizations with large-diameter catheters and/or long total indwelling time periods. Patients with central venous occlusion verified by CT or MRT venography and need for central venous access should be referred for endovascular intervention.

Catheter-associated bloodstream infection is highly prevalent and often associated with fatal complications. Some studies have shown that applying preventive interventions could help to reduce and control this type of infection. To determine whether a new consensus protocol for the manipulation and maintenance of central venous catheters would decrease catheter-associated bloodstream infections (CA-BSIs) in paediatric patients. To evaluate its compliance in intensive care units. Prospective study in the paediatric (PICU) and neonatal (NICU) intensive cares units, haematology, oncology and hospital wards in a Maternal and Paediatric reference Hospital in Barcelona. The study period is divided into two periods: before (first semester) and after the start of the new protocol (second semester) in 2007. The most important changes have been the insertion of the hermetic connection in the proximal and distal site (between the line and the syringe) of the central venous catheter (CVC), the labelling of the medication line and the CVC with the date of placement. A check-list to evaluate compliance was introduced in both intensive care units (paediatrics and neonatal) during the second study period. The rates of bloodstream infection per 1000 catheter-days were assessed. The rate of bloodstream infections per 1000 catheter-days before and after the start of the new protocol was 5.7 and 4.9 in PICU; 24.6 and 18.0 in NICU; 7.6 and 4.6 in haematology-oncology, and 11.9 and 10.3 in hospital wards. As regards compliance to the protocol, we found that proximal sealed connectors were used in more than 95% of the cases and up to 85% of the central venous catheter were labelled with the insertion date in both intensive care units. A consensus protocol for the use and maintenance of central venous catheters and healthcare worker training helped to control the rate of CA-BSIs. We reaffirm the importance of epidemiological surveillance as a measure for controlling nosocomial infections.

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

A 77-year-old woman was admitted due to AV graft thrombosis; given the technical impossibility of performing other native AV fistulas, we chose to insert a tunnelled central venous catheter. Considering the vascular history of the patient, the central venous catheter could not be placed into the internal jugular vein; it was therefore put into the left femoral vein. Following a 3-month-period of the catheter working properly, the patient was hospitalized due to sudden acute pain in the left thigh. In a few days the patient developed an important haematoma with serious anemization in the left lower limb. Ultrasonography showed the presence of a fistula between the left common femoral artery and the femoral vein, leading to the subsequent successful positioning of a stent into the common femoral artery through right trans-femoral access. Angiography examination showed the femoral vein patency along the proximal stretch with respect to the function of the tunnelled venous catheter.

To evaluate the efficacy and safety of the Hydrolyser catheter for per,cutaneous treatment of massive pulmonary embolism in pigs. Twelve pigs, each weighing between 55 kg and 89 kg, were used. Radio-opaque 9 cm x 0.8 cm and 4.5 cm x 0.8 cm clots, produced by mixing pig blood with iodinated contrast agent in vacutainers, were injected via the jugular vein until central pulmonary embolism (main and proximal lobar arteries) was obtained with significant systemic and pulmonary hemodynamic modifications. From a femoral approach, the 7-French Hydrolyser thrombectomy catheter was run over a 0.025-inch (0.64-mm) guide wire to remove the pulmonary emboli. Hemodynamic, gasometric and angiographic monitoring was performed before and after treatment. The procedure's safety and completeness of emboli removal was assessed by cardiopulmonary autopsy. Three of the 12 pigs died during embolization. Thrombectomy was therefore performed in 9, and central emboli could be obtained in 7 of the 9. The Hydrolyser could be manipulated only in central pulmonary arteries and could aspirate only central emboli in 5 of the 7 pigs that had them. Despite minimal angiographic improvement seen in these 5, there was no significant hemodynamic and gasometric improvement after treatment. The procedure induced an increase in free hemoglobin blood levels. Autopsies revealed an average of 2 endothelial injuries per pig (mainly adherent endocardial thrombi) in both nontreated (n = 3) and Hydrolyser-treated (n = 9) groups. The Hydrolyser thrombectomy catheter can be promptly positioned and easily steered in central pulmonary arteries. It can be used to partially remove central emboli, but not peripheral pulmonary emboli. Most of the injuries observed may not have been strictly related to Hydrolyser use. The pig might not be a suitable animal model for treatment of massive pulmonary embolism. (author)

Total parenteral alimentation (TPA) was delivered to 80 infants via indwelling umbilical artery and to 9 via indwelling umbilical venous catheters. The primary indication for catheter placement and maintenance was monitoring of arterial blood gases (umbilical venous catheter tip in left atrium) in a group of sick neonates requiring increased inspired oxygen or assisted ventilation. Results were compared with those from 23 infants who had tunnelled jugular catheters for a variety of chronic medical and surgical problems preventing gastric or intestinal feeding. A mean weight gain was achieved in both groups. Mortality and morbidity rates were similar in both groups. The most common complications were infection and thrombotic phenomena. Metabolic complications were few. It is concluded that infusing TPA solutions via indwelling umbilical catheters presents no greater risk than infusion via tunnelled jugular catheters, and provides a method for supplying adequate caloric intake for growth during the acute stage of illness.

To compare the rates of central venous stenosis in patients undergoing hemodialysis who underwent disruption of fibrin sheath with percutaneous transluminal angioplasty balloons and those who underwent over-the-wire catheter exchange. This study is a retrospective review of 209 percutaneous transluminal angioplasty balloon disruption and 1304 over-the-wire catheter exchange procedures performed in 753 patients. Approval from the Human Investigations Committee was obtained for this study. Up to 10-year follow-up was performed. A χ 2 test was used to compare the rates of central venous stenosis after balloon disruption versus catheter exchange. A t-test was used to compare time to central venous stenosis development. Of the 753 patients in the study, 127 patients underwent balloon disruption of fibrin sheath and 626 had catheter exchange. Within the balloon disruption group, 18 (14.2%) of 127 patients subsequently developed central venous stenosis, compared with 44 (7.0%) of 626 in the catheter exchange group (P 2 test). Time to central venous stenosis development was approximately 3 years in both groups and not significantly different (1371 and 1010 days, P = 0.20). A total of 25.2% of patients in the balloon disruption group had four or more subsequent catheter exchanges, versus 12.6% in the catheter exchange group (P 2 test). In conclusions, there is a possible association between percutaneous transluminal angioplasty balloon disruption of fibrin sheath and late-onset central venous stenosis. Because venography was not routinely performed in catheter exchange patients, future randomized studies are necessary to confirm these findings.

Zayed, Mohamed A.; De Silva, Gayan S.; Ramaswamy, Raja S.; Sanchez, Luis A.

2017-01-01

Cavoatrial deep venous thrombosis (DVT) is diagnosed with increasing prevalence. It can be managed medically with anticoagulation or with directed interventions aimed to efficiently reduce the thrombus burden within the target venous segment. The type of management chosen depends greatly on the etiology and chronicity of the thrombosis, existing patient comorbidities, and the patient's tolerance to anticoagulants and thrombolytic agents. In addition to traditional percutaneous catheter-based pharmacomechanical thrombolysis, other catheter-based suction thrombectomy techniques have emerged in recent years. Each therapeutic modality requires operator expertise and a coordinated care paradigm to facilitate successful outcomes. Open surgical thrombectomy is alternatively reserved for specific patient conditions, including intolerance of anticoagulation, failed catheter-based interventions, or acute emergencies.

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.

We present a case of isolated calyx that was mistaken for a large cyst. A 47-year-old woman was referred for sclerotherapy of a large cystic lesion on her left kidney. Computed tomography (CT) and ultrasound showed that the cystic lesion was a large cyst. We noticed that the cystic lesion was not a typical simple cyst, even after two sessions of catheter-mediated sclerotherapy. Isolated calyx was presumed by medical history review and was confirmed by aspirated fluid analysis and far delayed-phase CT after intravenous contrast injection. We performed meticulous selective arterial embolization for an isolated calyx and inserted a catheter that could be removed without complication.

To obtain a quantitative estimate of the impact on infectious complications of using transparent dressings with intravenous catheters. Meta-analysis of all studies published in the English literature, including abstracts, letters, and reports that examined the primary research question of infection risks associated with transparent compared with gauze dressings for use on central and peripheral venous catheters. Studies were identified by use of the MEDLINE database using the indexing terms occlusive dressings, transparent dressings, and infection and by review of referenced bibliographies. Seven of the 15 studies (47%) of central venous catheters and seven of 12 studies (58%) of peripheral catheters met our inclusion criteria for analysis. All studies used a prospective cohort design, utilized hospitalized patients, and reported at least one of our defined outcomes. Data for each study were abstracted independently by three investigators. At least three studies were used in the analysis of each outcome. Applying a Mantel-Haenszel chi 2 analysis, use of transparent dressings on central venous catheters was significantly associated with an elevated relative risk (RR) of catheter tip infection (RR = 1.78; 95% confidence interval [CI], 1.38 to 2.30). Catheter-related sepsis (RR = 1.69; 95% CI, 0.97 to 2.95) and bacteremia (RR = 1.63; 95% CI, 0.76 to 3.47) were both associated with an elevated RR. Use of transparent dressings on peripheral catheters was associated with an elevated RR of catheter-tip infection (RR = 1.53; 95% CI, 1.18 to 1.99) but not phlebitis (RR = 1.02; 95% CI, 0.86 to 1.20), infiltration (RR = 1.12; 95% CI, 0.92 to 1.37), or skin colonization (RR = 0.99; 95% CI, 0.90 to 1.09). The results demonstrated a significantly increased risk of catheter-tip infection with the use of transparent compared with gauze dressings when used with either central or peripheral catheters. An increased risk of bacteremia and catheter sepsis associated with the use of

Peripherally inserted central catheters (PICCs) are associated with central line-associated bloodstream infection (CLABSI). The magnitude of this risk relative to central venous catheters (CVCs) is unknown. To compare risk of CLABSI between PICCs and CVCs. MEDLINE, CinAHL, Scopus, EmBASE, and Cochrane CENTRAL were searched. Full-text studies comparing the risk of CLABSI between PICCs and CVCs were included. Studies involving adults 18 years of age or older who underwent insertion of a PICC or a CVC and reported CLABSI were included in our analysis. Studies were evaluated using the Downs and Black scale for risk of bias. Random effects meta-analyses were used to generate summary estimates of CLABSI risk in patients with PICCs versus CVCs. Of 1,185 studies identified, 23 studies involving 57,250 patients met eligibility criteria. Twenty of 23 eligible studies reported the total number of CLABSI episodes in patients with PICCs and CVCs. Pooled meta-analyses of these studies revealed that PICCs were associated with a lower risk of CLABSI than were CVCs (relative risk [RR], 0.62; 95% confidence interval [CI], 0.40-0.94). Statistical heterogeneity prompted subgroup analysis, which demonstrated that CLABSI reduction was greatest in outpatients (RR [95% CI], 0.22 [0.18-0.27]) compared with hospitalized patients who received PICCs (RR [95% CI], 0.73 [0.54-0.98]). Thirteen of the included 23 studies reported CLABSI per catheter-day. Within these studies, PICC-related CLABSI occurred as frequently as CLABSI from CVCs (incidence rate ratio [95% CI], 0.91 [0.46-1.79]). Only 1 randomized trial met inclusion criteria. CLABSI definition and infection prevention strategies were variably reported. Few studies reported infections by catheter-days. Although PICCs are associated with a lower risk of CLABSI than CVCs in outpatients, hospitalized patients may be just as likely to experience CLABSI with PICCs as with CVCs. Consideration of risks and benefits before PICC use in inpatient

Catheter-related bloodstream infections (CRBSI) constitute an important cause of hospital-acquired infection associated with morbidity, mortality, and cost. The aim of these guidelines is to provide updated recommendations for the diagnosis and management of CRBSI in adults. Prevention of CRBSI is excluded. Experts in the field were designated by the two participating Societies (Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica and the Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias). Short-term peripheral venous catheters, non-tunneled and long-term central venous catheters, tunneled catheters and hemodialysis catheters are covered by these guidelines. The panel identified 39 key topics that were formulated in accordance with the PICO format. The strength of the recommendations and quality of the evidence were graded in accordance with ESCMID guidelines. Recommendations are made for the diagnosis of CRBSI with and without catheter removal and of tunnel infection. The document establishes the clinical situations in which a conservative diagnosis of CRBSI (diagnosis without catheter removal) is feasible. Recommendations are also made regarding empirical therapy, pathogen-specific treatment (coagulase-negative staphylococci, Sthaphylococcus aureus, Enterococcus spp, Gram-negative bacilli, and Candida spp), antibiotic lock therapy, diagnosis and management of suppurative thrombophlebitis and local complications.

2016-07-01

Full Text Available The use of endovascular catheters is a routine practice in secondary and tertiary care level hospitals. The short-term use of peripheral catheters has been found to be associated with the risk of nosocomial bacteraemia, resulting in morbidity and mortality. Staphylococcus aureus is mostly associated with peripheral catheter insertion. This Consensus Document has been prepared by a panel of experts of the Spanish Society of Cardiovascular Infections, in cooperation with experts from the Spanish Society of Internal Medicine, Spanish Society of Chemotherapy, and the Spanish Society of Thoracic-Cardiovascular Surgery, and aims to define and establish guidelines for the management of short duration peripheral vascular catheters. The document addresses the indications for insertion, catheter maintenance, registering, diagnosis and treatment of infection, indications for removal, as well as placing an emphasis on continuous education as a drive toward quality. Implementation of these guidelines will allow uniformity in use, thus minimizing the risk of infections and their complications.

Tricuspid valve endocarditis following central venous cannulation: The increasing problem of catheter related infection

Directory of Open Access Journals (Sweden)

Suresh Babu Kale

2013-01-01

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.

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

Data on management of upper extremity deep vein thrombosis (UEDVT) in patients with cancer is limited. The objective of this study was to determine risk factors for UEDVT and the rates of recurrence and bleeding in a real-world setting. Retrospective review of consecutive patients assessed for cancer-associated UEDVT. Outcome measures were recurrent venous thromboembolism (VTE), and major and clinically relevant non-major bleeding (CRNMB). Risk factors for recurrent VTE and bleeding were assessed. Mean duration of follow-up was 7.2 months. Two hundred cases were identified; 69% were associated with a central line. Non-line associated UEDVT occurred more frequently in the setting of breast cancer, lung cancer and documented local mass effect. The incidence of recurrent VTE was 18.5%, of which 14 (37.8%) were ipsilateral UEDVT. The risk of recurrence is higher with male gender (HR 2.0, 95% CI; 1.0-4.0). Major and CRNMB occurred in 1% and 11.5%, respectively. Concurrent use of an antiplatelet agent was associated with a higher risk of CRNMB compared to anticoagulant therapy alone (HR 3.9, 95% CI; 1.4-10.7). Presence of a venous catheter was the primary risk factor for UEDVT, however, extrinsic compression by local tumour may be just as important for some cancer types. Furthermore, the majority of recurrent events did not occur in the same upper limb suggesting that UEDVT may be predictive of increased thrombotic risk rather than just a local effect of catheters.

Catheter Occlusion in Home Infusion: The Influence of Needleless Connector Design on Central Catheter Occlusion.

Science.gov (United States)

Williams, Ann

Thrombotic catheter occlusion is a common complication associated with central venous catheters (CVCs). A wide variety of needleless connectors that differ greatly in design and function are available for use with CVCs; however, there are a limited number of studies comparing the catheter occlusion rate associated with differently designed needleless connectors. This retrospective observational study compared occlusion rates associated with a split-septum neutral-displacement needleless connector versus those of a solid-surface neutral-reflux needleless connector in patients undergoing home infusion therapy. The neutral-reflux needleless connector was associated with a significant reduction in occlusion rate and thrombolytic use versus the neutral-displacement needleless connector.

Background Placement of central venous port catheters (CVPS) and peripherally inserted central catheters (PICC) is an integral component of state-of-the-art patient care. In the era of increasing cost awareness, it is desirable to have more information to comprehensively assess both procedures. Purpose To perform a retrospective analysis of interventional radiologic implantation of CVPS and PICC lines in a large patient population including a cost analysis of both methods as well as an investigation the learning curve in terms of the interventions' durations. Material and Methods All CVPS and PICC line related interventions performed in an interventional radiology department during a three-year period from January 2011 to December 2013 were examined. Documented patient data included sex, venous access site, and indication for CVPS or PICC placement. A cost analysis including intervention times was performed based on the prorated costs of equipment use, staff costs, and expenditures for disposables. The decrease in intervention duration in the course of time conformed to the learning curve. Results In total, 2987 interventions were performed by 16 radiologists: 1777 CVPS and 791 PICC lines. An average implantation took 22.5 ± 0.6 min (CVPS) and 10.1 ± 0.9 min (PICC lines). For CVPS, this average time was achieved by seven radiologists newly learning the procedures after performing 20 CVPS implantations. Total costs per implantation were €242 (CVPS) and €201 (PICC lines). Conclusion Interventional radiologic implantations of CVPS and PICC lines are well-established procedures, easy to learn by residents, and can be implanted at low costs.

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 %.

Serious Gaming to Improve the Safety of Central Venous Catheter Placement

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.

To evaluate the efficacy and safety of the thrombolytic tenecteplase, a fibrin-specific recombinant tissue plasminogen activator, for restoring function to dysfunctional central venous catheters (CVCs). In this double-blind, placebo-controlled study, eligible patients with dysfunctional nonhemodialysis CVCs were randomly assigned to two treatment arms. In the first arm (TNK-TNK-PBO), patients received an initial dose of intraluminal tenecteplase (TNK) (up to 2 mg), a second dose of tenecteplase if indicated, and a third placebo (PBO) dose. In the PBO-TNK-TNK arm, placebo was instilled first followed by up to two doses of tenecteplase, if needed, for restoration of catheter function. After administration of each dose, CVC function was assessed at 15, 30, and 120 minutes. There were 97 patients who received either TNK-TNK-PBO (n = 50) or PBO-TNK-TNK (n = 47). Within 120 minutes of initial study drug instillation, catheter function was restored to 30 patients (60%) in the TNK-TNK-PBO arm and 11 patients (23%) in the PBO-TNK-TNK arm, for a treatment difference of 37 percentage points (95% confidence interval 18-55; P = .0002). Cumulative restoration rates for CVC function increased to 87% after the second dose of tenecteplase in both study arms combined. Two patients developed a deep vein thrombosis (DVT) after exposure to tenecteplase; one DVT was considered to be drug related. No cases of intracranial hemorrhage, major bleeding, embolic events, catheter-related bloodstream infections, or catheter-related complications were reported. Tenecteplase was efficacious for restoration of catheter function in these study patients with dysfunctional CVCs. Copyright © 2010 SIR. Published by Elsevier Inc. All rights reserved.

In a intensive care unit (ICU) there are many factors that can lead to the occurrence of adverse events. A high percentage of these events are associated with the administration of drugs. Diagnostic tests, such as computed tomography, is common in critically ill patients and technique can be performed with injection of contrast agent to enhance the visualization of soft tissue. The contrast is a medication and the nurse is responsible for its proper administration. The management of the critically ill patient is complex. ICU team and radiology shares responsibility for the care and safety of the patient safety during the transfer and performing tests with contrast. The World Health Organisation patient safety strategies, recommends analysing errors and learning from them. Therefore, it was decided to investigate the causes of the category E severity adverse events that occurred in a patient who was admitted to the ICU for septic shock of abdominal origin. An abdominal computed tomography was performed with contrast which was injected through a central venous catheter. The contrast did not appear in the image. What happened? Causal analysis helped to understand what triggered the event. A care plan and an algorithm were drafted to prevent it from happening again, with the following objectives: improving knowledge, skills and promoting positive attitudes towards patient safety, working at primary, secondary and tertiary care levels.

Venous access: options, approaches and issues

International Nuclear Information System (INIS)

Asch, M.R.

2001-01-01

Venous access is an essential part of medical practice. It is needed to obtain blood samples to make the diagnosis and to administer fluids or medicines as part of treatment. Although relatively new in the history of medicine, the placement and maintenance of the various venous access devices now occupies a significant portion of many vascular and interventional radiology practices. Thus, it is important to have a thorough understanding of these devices and their uses. The first long-term venous access devices were used in 1973. These were placed via a surgical cut-down on the subclavian vein. In 1982, the first subcutaneous implantable ports were described. These procedures were initially performed by surgeons, but over the last 5-10 years, both the insertion and management of these devices has shifted to interventional radiologists. Peripherally inserted central catheter (PICC) lines have almost completely supplanted the use of standard central lines (Fig. 1). A number of factors have facilitated this - namely, ready and less expensive room access, outpatient procedure and radiologists' accessibility and familiarity with image-guidance procedures and catheters and guide wires.

Edirisinghe, P A S; Busuttil, A

2006-02-01

Haemodialysis access is an essential requirement for haemodialysis treatment in end-stage renal disease. The common forms are arteriovenous fistula (AVF) and arteriovenous grafts in ante-cubital fossa, forearm and upper thigh. Sometimes temporary or immediate access is created via a subclavian catheter or internal jugular catheter. This report is on a 79-year-old man who was suffering from chronic renal failure with a non-functional peripheral AVF; he was being dialysed through a permanent subclavian catheter and he became depressed due to continuing deterioration of his health. He used the easily accessible haemodialysis site as the method of suicide by cutting the tube that connected with the main vessel in his chest and bled to death. This highlights the requirement to assess carefully the patient's mental state in those on chronic haemodialysis, even though very few similar fatal cases have been previously reported.

To evaluate, in a phase III, single-arm study, the safety and efficacy of the thrombolytic agent tenecteplase in restoring function to dysfunctional central venous catheters (CVCs). Pediatric and adult patients with dysfunctional CVCs were eligible to receive as much as 2 mL (2 mg) of intraluminal tenecteplase, which was left to dwell in the CVC lumen for a maximum of 120 minutes. If CVC function was not restored at 120 minutes, a second dose was instilled for an additional 120 minutes. Tenecteplase was administered to 246 patients. Mean patient age was 44 years (range, 0-92 y); 72 patients (29%) were younger than 17 years of age. Chemotherapy was the most common reason for catheter insertion. Restoration of CVC function was achieved in 177 patients (72%) within 120 minutes after the first dose. After instillation of a maximum of two doses of tenecteplase, CVC function was restored in 200 patients (81%), with similar frequencies in pediatric (83%) and adult (80%) patients. Adverse events (AEs) were reported in 31 patients (13%); fever (2%), neutropenia (1%), and nausea (0.8%) were most common. One serious AE, an allergic hypersensitivity reaction, was judged to be related to tenecteplase and/or a chemotherapeutic agent that the patient was receiving concurrently. Consecutive administration of one or two doses of tenecteplase into CVCs showed efficacy in the restoration of catheter function in patients with dysfunctional CVCs. Copyright © 2011 SIR.

Traditional anticoagulant treatment of deep venous thrombosis (DVT) in the upper extremities (UEDVT) is associated with a relatively high incidence of postthrombotic syndrome (PTS). Catheter-directed thrombolysis (CDT) for UEDVT would provide efficient thrombolysis with less subsequent PTS than during traditional anticoagulation. Primary efficacy, complications, and long-term results after CDT are reported in a retrospective cohort (2002-2007) of patients (n = 30) with DVT in the upper extremities. PTS was assessed by a modified Villalta scale. UEDVT was unprovoked in 11 (37%) cases and effort related in 9 (30%) cases. The median duration of symptoms prior to CDT was 7.0 days (range, 1-30); median duration of thrombolysis treatment, 70 h (range, 24-264 h); and the median amount of rt-PA infused during CDT, 52 mg (range, 19-225 mg). Major bleeding was registered in three (9%) patients, and CDT was stopped prematurely in three patients due to local hematoma. No intracerebral bleeding, clinical pulmonary embolism, or deaths occurred during treatment. Grade II (>50%) or III (>90%) lysis was present in 29 patients (97%) at the end of CDT. Bleeding complications increased by each day of delay from the debut of symptoms to the start of treatment (OR, 1.20; 95% CI, 1.01-1.42). At follow-up (n = 29; median, 21 months; range, 5-58 months), 11 (38%) patients had occluded veins, whereas 18 (62%) had patent veins. However, stenosis of varying severity was present in eight of those with a patent vein. No patients had severe PTS, whereas six (21%) experienced mild PTS. In conclusion, our retrospective cohort study of patients with UEDVT showed that treatment restored venous drainage, with a subsequent low frequency of mild PTS at follow-up. Early intervention with CDT prevented bleeding complications.

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

Full Text Available 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.

Little data are available concerning the relation between the muscular pumping mechanism and the variation of superficial and deep venous pressure during normal action of the calf pump; therefore we undertook this study to determine the pressure values in three compartments of the calf and in the deep and the superficial venous system and to establish correlation between muscular and venous pressure. Nine healthy young women with a mean age of 23 years (range 19 to 28 years) were examined. In the same calf, a muscular catheter was placed in the deep posterior compartment (DPC), in the superficial posterior compartment (SPC), and in the anterior tibial compartment (ATC), and a vascular catheter was placed in the popliteal vein and in the greater saphenous vein (GSV). The five lines of pressure were simultaneously recorded in the following situations: at rest, during Valsalva maneuver, foot flexion, and foot extension. The situation was studied with the patient in the following positions: decubitus, sitting, standing, and squatting. A final continuous recording was carried out after the patient had been walking for 5 minutes. Mean values with standard errors of muscular and venous pressure were established in each situation. At rest and during Valsalva maneuver, the muscular pressures did not vary, whereas venous pressures increased significantly when the patient was sitting and standing. On the other hand, squatting was associated with a rise in the muscular and vein pressures. Foot flexion entailed a significant increase in the ATC pressure and a rise in the GSV pressure, whereas foot extension caused the DPC pressure to rise without venous pressure modifications. Walking was associated with an alternating increase in the DPC, SPC, GSV and popliteal vein pressures when the foot was compressed to floor followed by a significant decrease when the foot pressure was released. The variations in the deep and superficial venous pressures when the patient is sitting and

Objective: To evaluate the radiofrequency catheter ablation for type I atrial flutter through application of Holo catheter labelling with anatomic imaging localization to ablate the isthmus of IVCTA during complete double-way block. Methods: Eleven cases with type I atrial flutter undergone Holo catheter labelling technique and consecution with conduction time change of coronary venous sinus orifice with-right atrial lower lateral wall pace excitation, were performed with radiofrequency catheter ablation for the isthmus outcoming with complete double-way conduction block. Results: All together 11 cases with 4 of atrial flutter and 7 of sinus rhythm were undergone radiofrequency catheter ablation resulting with double-way conduction block of the isthmus accompanied by prolongation of right atrial conduction time 56.0 ± 2.3 ms and 53.0 ± 4.6 ms respectively. The right atrial excitation appeared to be in clockwise and counter-clockwise of single direction. No recurrence occurred during 3-34 months follow up with only one showing atrial fibrillation. Conclusions: The application of Holo catheter labelling technique with anatomic imaging localization to achieve the double-way conduction block by radiofrequency catheter ablation of TVC-TA isthmus, is a reliable method for treating atrial flutter

Peripherally Inserted Central Catheters (PICCs) are increasingly being used to provide short to medium-term central venous access. The current study was designed to test the hypothesis that PICC valve technology does not influence PICC occlusion rates. Intensive care unit (ICU) patients who required a PICC were randomized to one of three types of dual lumen PICC (open ended non-valved, Groshong valve, PASV valve). PICC occlusions were recorded and managed with a protocol that used urokinase. A total of 102 patients were recruited to the study. The overall risk of occlusion per catheter was 35% (95% CI 26% to 44%). The overall rate of occlusion was 76 occlusions per 1000 catheter days (95% CI 61 to 95). Presence or type of valve did not significantly influence this rate (open-ended non-valved PICC 38% of catheters, 79 occlusions per 1000 catheter days; Groshong 38% of catheters, 60 occlusions per 1000 catheter days; PASV 27% of catheters, 99 occlusions per 1000 catheter days). The dose of urokinase required to treat PICC occlusions did not significantly differ between PICC types. Valved PICCs do not appear to influence PICC occlusion rates.

Central Venous Occlusion in the Hemodialysis Patient.

Krishna, Vinay Narasimha; Eason, Joseph B; Allon, Michael

2016-11-01

Central venous stenosis (CVS) is encountered frequently among hemodialysis patients. Prior ipsilateral central venous catheterization and cardiac rhythm device insertions are common risk factors, but CVS can also occur in the absence of this history. Chronic CVS can cause thrombosis with partial or complete occlusion of the central vein at the site of stenosis. CVS is frequently asymptomatic and identified as an incidental finding during imaging studies. Symptomatic CVS presents most commonly as an upper- or lower-extremity edema ipsilateral to the CVS. Previously unsuspected CVS may become symptomatic after placement of an ipsilateral vascular access. The likelihood of symptomatic CVS may be affected by the central venous catheter (CVC) location; CVC side; duration of CVC dependence; type, location, and blood flow of the ipsilateral access; and extent of collateral veins. Venous angiography is the gold standard for diagnosis. Percutaneous transluminal angioplasty and stent placement can improve the stenosis and alleviate symptoms, but CVS typically recurs frequently, requiring repeated interventions. Refractory symptomatic CVS may require ligation of the ipsilateral vascular access. Because no available treatment option is curative, the goal should be to prevent CVS by minimizing catheters and central vein instrumentation in patients with chronic kidney disease and dialysis patients.

2016-10-01

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

With good catheter care, rates of mechanical, infectious and thrombotic complications are low and compare favourably with those of traditional central venous catheters. Even in the case...... of occlusion or infection, fibrinolytics and antibiotic locks often allow the catheter to be retained....

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.)

Many instruments for measurement of peripheral venous catheter (PVC)-related phlebitis are available, but no consensus exists on their applicability in clinical practice. This absence of consensus affects the ability to identify and compare proportions of PVCs causing phlebitis within and across hospitals as the range varies between 2% and 62% in previous studies. We hypothesised that the instruments' ability to identify phlebitis varies. The aim of this study is to illustrate the complexity of application of phlebitis instruments to a clinical dataset. In this cross-sectional study, we applied 17 instruments for phlebitis identification (divided into three groups [instruments using definitions, severity rating systems, and scoring systems]) to PVCs in adult patients admitted to 12 inpatient units at Karolinska University Hospital in Sweden. We calculated the proportion of PVCs causing phlebitis on the basis of each instrument's minimum criterion for phlebitis. We also analysed each instrument's face validity. We compared proportions using the Z test. On the basis of data collected between Feb 2, 2009, and Feb 20, 2009, May 18, 2009, and June 5, 2009, and Feb 8, 2010, and Feb 26, 2010, we applied 17 instruments for phlebitis identification (eight instruments using definitions, seven severity rating systems, and two scoring systems) to 1175 observed PVCs in 1032 patients. The highest number of PVCs causing phlebitis generated by definitions was 137 (11·7%), by severity rating systems was 395 (33·6%), and by scoring systems was 363 (30·9%). The proportion generated by instruments using definitions was significantly different to that of both the severity rating (difference 21·9% [95% CI 18·6-25·2]; pphlebitis published in the scientific community. From a work environment and patient safety perspective, clinical staff engaged in PVC management should be aware of the absence of adequately validated instruments for phlebitis assessment. We suggest that researchers

To evaluate if body surface temperature close to the central venous catheter insertion area is different when patients develop catheter-related bloodstream infections. Observational cross-sectional study. Using a non-contact infrared thermometer, 3 consecutive measurements of body surface temperature were collected from 39 patients with central venous catheter on the following sites: nearby the catheter insertion area or totally implantable catheter reservoir, the equivalent contralateral region (without catheter), and forehead of the same subject. A total of 323 observations were collected. Respectively, both in male and female patients, disregarding the occurrence of infection, the mean temperature on the catheter area minus that on the contralateral region (mean ± standard deviation: -0.3±0.6°C versus-0.2±0.5ºC; p=0.36), and the mean temperature on the catheter area minus that on the forehead (mean ± standard deviation: -0.2±0.5°C versus-0.1±0.5ºC; p=0.3) resulted in negative values. Moreover, in infected patients, higher values were obtained on the catheter area (95%CI: 36.6-37.5ºC versus 36.3-36.5ºC; p0.55ºC versus-0.22 - -0.10ºC; p<0.01). Using a non-contact infrared thermometer, patients with catheter-related bloodstream infections had higher temperature values both around catheter insertion area and in the subtraction of the temperatures on the contralateral and forehead regions from those on the catheter area.

Most of the patients with iliofemoral thrombosis treated with anticoagulants only are affected with postthrombotic syndrome (PTS) that worsens the patients' quality of life. In the acute phase of proximal deep venous thrombosis (DVT) catheter-directed (CDT) and pharmacomechanical thrombolysis may be a reasonable alternative therapeutic method. Our aim was to summarize our results using these methods. Since 2009 twenty-four patients with iliofemoral DVT were treated with these endovascular procedures and with stenting at our Institution. The median age of the patients was 35.83 ± 15.9 years, the female: male ratio was approximately 2:1. The mean time between the onset of the symptoms and the procedures was eleven days. CDT alone was performed in 8 patients, thrombus aspiration in addition to CDT using AngioJet device in 16 patients; in 19 cases the procedure was completed with venous stenting. During the follow-up we performed US examinations and estimated the severity of PTS by Villalta-scale. The total recanalization-rate was more than 50%, which even improved during the follow-up. The total lysis time and the amount of used recombinant tissue plasminogen activator decreased significantly by applying the AngioJet. We did not find any severe PTS among our patients during the follow-up visits. Our data suggests that these methods can be used efficiently and safely in the treatment of acute iliofemoral DVT.

Centers for Medicare and Medicaid Services have determined that chronic dialysis units should have 45%. A multidisciplinary program was established with goals of decreasing catheter rates in order to decrease central line-associated bloodstream infections, decrease mortality associated with central line-associated bloodstream infection, decrease hospital days, and provide savings to the healthcare system. We collected the catheter rates within three dialysis centers served over a 5-year period. Using published data surrounding the incidence and related costs of central line-associated bloodstream infection and mortality per catheter day, the number of central line-associated bloodstream infection events, the costs, and the related mortality could be determined prior to and after the initiation of the dialysis access program. An organized dialysis access program resulted in a 82% decrease in the number of central venous catheter days which lead to a concurrent reduction in central line-associated bloodstream infection and deaths. As a result of creating an access program, central venous catheter rates decreased from an average rate of 45% to 8%. The cost savings related to the program was calculated to be over US$5 million. The decrease in the number of mortalities is estimated to be between 13 and 27 patients. We conclude that a formalized access program decreases catheter rates, central line-associated bloodstream infection, and the resultant hospitalizations, mortality, and costs. Areas with high hemodialysis catheter rates should develop access programs to better serve their patient population.

Ultrasound-guided Central Venous Catheterization (CVC) for temporary vascular access, preferably using the right internal jugular vein, is widely accepted by nephrologists. However CVC is associated with numerous potential complications, including death. We describe the finding of a rare left-sided partial anomalous pulmonary vein connection during central venous catheterization for continuous renal replacement therapy (CRRT). Ultrasound-guided cannulation of a large bore temporary dual-lumen Quinton-Mahurkar catheter into the left internal jugular vein was performed for CRRT initiation in a 66 year old African-American with sepsis-related oliguric acute kidney injury. The post-procedure chest X-ray suggested inadvertent left carotid artery cannulation. Blood gases obtained from the catheter showed high partial pressure of oxygen (PO2) of 140 mmHg and low partial pressure of carbon dioxide (PCO2) of 22 mmHg, suggestive of arterial cannulation. However, the pressure-transduced wave forms appeared venous and Computed Tomography Angiography located the catheter in the left internal jugular vein, but demonstrated that the tip of the catheter was lying over a left pulmonary vein which was abnormally draining into the left brachiocephalic (innominate) vein rather than into the left atrium. Although several mechanical complications of dialysis catheters have been described, ours is one of the few cases of malposition into an anomalous pulmonary vein, and highlights a sequential approach to properly identify the catheter location in this uncommon clinical scenario.

Endovascular Treatment Options in the Management of Lower Limb Deep Venous Thrombosis

International Nuclear Information System (INIS)

Nazir, Sarfraz Ahmed; Ganeshan, Arul; Nazir, Sheraz; Uberoi, Raman

2009-01-01

Lower limb deep vein thrombosis (DVT) is a common cause of significant morbidity and mortality. Systemic anticoagulation therapy is the mainstay of conventional treatment instituted by most physicians for the management of DVT. This has proven efficacy in the prevention of thrombus extension and reduction in the incidence of pulmonary embolism and rethrombosis. Unfortunately, especially in patients with severe and extensive iliofemoral DVT, standard treatment may not be entirely adequate. This is because a considerable proportion of these patients eventually develops postthrombotic syndrome. This is characterized by chronic extremity pain and trophic skin changes, edema, ulceration, and venous claudication. Recent interest in endovascular technologies has led to the development of an assortment of minimally invasive, catheter-based strategies to deal with venous thrombus. These comprise catheter-directed thrombolysis, percutaneous mechanical thrombectomy devices, adjuvant venous angioplasty and stenting, and inferior vena cava filters. This article reviews these technologies and discusses their current role as percutaneous treatment strategies for venous thrombotic conditions.

Intracorporeal knotting of a femoral nerve catheter

Directory of Open Access Journals (Sweden)

Ghanem, Mohamed

2015-01-01

Full Text Available Peripheral nerve catheters are effective and well-established tools to provide postoperative analgesia to patients undergoing orthopedic surgery. The performance of these techniques is usually considered safe. However, placement of nerve catheters may be associated with a considerable number of side effects and major complications have repeatedly been published. In this work, we report on a patient who underwent total knee replacement with spinal anesthesia and preoperative insertion of femoral and sciatic nerve catheters for postoperative analgesia. During insertion of the femoral catheter, significant resistance was encountered upon retracting the catheter. This occurred due to knotting of the catheter. The catheter had to be removed by operative intervention which has to be considered a major complication. The postoperative course was uneventful. The principles for removal of entrapped peripheral catheters are not well established, may differ from those for neuroaxial catheters, and range from cautious manipulation up to surgical intervention.

Current guidelines recommend using antiseptic- or antibiotic-impregnated central venous catheters (CVCs) if, following a comprehensive strategy to prevent catheter-related blood stream infection (CR-BSI), infection rates remain above institutional goals based on benchmark values. The purpose of this study was to determine if chlorhexidine/silver sulfadiazine-impregnated CVCs could decrease the CR-BSI rate in an intensive care unit (ICU) with a low baseline infection rate. Pre-intervention and post-intervention observational study in a 24-bed surgical/trauma/burn ICU from October, 2002 to August, 2005. All patients requiring CVC placement after March, 2004 had a chlorhexidine/silver sulfadiazine-impregnated catheter inserted (post-intervention period). Twenty-three CR-BSIs occurred in 6,960 catheter days (3.3 per 1,000 catheter days)during the 17-month control period. After introduction of chlorhexidine/silver sulfadiazine-impregnated catheters, 16 CR-BSIs occurred in 7,732 catheter days (2.1 per 1,000 catheter days; p = 0.16). The average length of time required for an infection to become established after catheterization was similar in the two groups (8.4 vs. 8.6 days; p = 0.85). Chlorhexidine/silver sulfadiazine-impregnated catheters did not result in a statistically significant change in the microbiological profile of CR-BSIs, nor did they increase the incidence of resistant organisms. Although chlorhexidine/silver sulfadiazine-impregnated catheters are useful in specific patient populations, they did not result in a statistically significant decrease in the CR-BSI rate in this study, beyond what was achieved with education alone.

Congenital anomalies of the inferior vena cava (IVC) are increasingly recognized with CT and venography techniques. Although many patients with IVC anomalies are asymptomatic, recent studies have suggested an association with venous thromboembolism. We report the case of a 62-year-old woman with extensive venous clot involving the infrarenal segment of a duplicated left IVC who underwent pharmacomechanical thrombectomy and tissue plasminogen activator catheter-directed thrombolysis with complete deep venous thrombosis resolution. To our knowledge this is the first reported case in the English literature of the use of a Trellis thrombectomy catheter in the setting of duplicated IVC.

Previous PICC Placement May Be Associated With Catheter-Related Infections in Hemodialysis Patients

International Nuclear Information System (INIS)

Butler, Philip J.; Sood, Shreya; Mojibian, Hamid; Tal, Michael G.

2011-01-01

Background: Catheter-related infections (CRIs) are a significant source of morbidity and mortality in hemodialysis patients. The identification of novel, modifiable risk factors for CRIs may lead to improved outcomes in this population. Peripherally inserted central catheters (PICCs) have been hypothesized to compromise vascular access due to vascular damage and venous thrombosis, whereas venous thrombosis has been linked to the development of CRIs. Here we examine the association between PICC placement and CRIs. Methods: A retrospective review was performed of all chronic hemodialysis catheter placements and exchanges performed at a large university hospital from September 2003 to September 2008. History of PICC line use was determined by examining hospital radiologic records from December 1993 to September 2008. Catheter-related complications were assessed and correlated with PICC line history. Results: One hundred eighty-five patients with 713 chronic tunneled hemodialysis catheter placements were identified. Thirty-eight of those patients (20.5%) had a history of PICC placement; these patients were more likely to have CRIs (odds ratio = 2.46, 95% confidence interval = 1.71–3.53, p < .001) compared with patients without a history of PICC placement. There was no difference between the two groups in age or number of catheters placed. Conclusion: Previous PICC placement may be associated with catheter-related infections in hemodialysis patients.

Despite the substantial progress that has been achieved in interventional cardiology and cardiac electrophysiology, endovascular intervention for the diagnosis and treatment of central nervous system (CNS) disorders such as stroke, epilepsy and CNS malignancy is still limited, particularly due to highly tortuous nature of the cerebral arterial and venous system. Existing interventional devices and techniques enable only limited and complicated access especially into intra-cerebral vessels. The aim of this study was to develop a micro-catheter magnetically-guided technology specifically designed for endovascular intervention and mapping in deep CNS vascular structures. Mapping of electrical brain activity was performed via the venous system on an animal dog model with the support of the NIOBE II system. A novel micro-catheter specially designed for endovascular interventions in the CNS, with the support of the NIOBE II technology, was able to reach safely deep intra-cerebral venous structures and map the electrical activity there. Such structures are not currently accessible using standard catheters. This is the first study demonstrating successful use of a new micro-catheter in combination with NIOBE II technology for endovascular intervention in the brain.

Purpose: We describe the technique, efficacy, and complications of fluoroscopy-guided implantation of a central venous access device using a peripherally accessed system (PAS) port via the forearm. Methods: Beginning in July 1994, 105 central venous access devices were implanted in 104 patients for the long-term infusion of antibiotics or antineoplasmic agents, blood products, or parenteral nutrition. The devices was inserted under fluoroscopic guidance with real-time venography from a peripheral route. Results: All ports were successfully implanted. There were no procedure-related complications. No thrombosis or local infection was observed; however, in six patients catheter-related phlebitis occurred. Conclusion: Fluoroscopy-guided implantation of a central venous access device using a PAS port via the forearm is safe and efficacious, and injection of contrast medium through a peripheral IV catheter before introduction of the catheter helps to avoid catheter-related phlebitis

Catheter type, access technique, and the catheter position should be selected considering to the anticipated duration of PN aiming at the lowest complication risks (infectious and non-infectious). Long-term (>7-10 days) parenteral nutrition (PN) requires central venous access whereas for PN 3 weeks subcutaneous tunnelled catheters or port systems are appropriate. CVC (central venous catheter) should be flushed with isotonic NaCl solution before and after PN application and during CVC occlusions. Strict indications are required for central venous access placement and the catheter should be removed as soon as possible if not required any more. Blood samples should not to be taken from the CVC. If catheter infection is suspected, peripheral blood-culture samples and culture samples from each catheter lumen should be taken simultaneously. Removal of the CVC should be carried out immediately if there are pronounced signs of local infection at the insertion site and/or clinical suspicion of catheter-induced sepsis. In case PN is indicated for a short period (max. 7-10 days), a peripheral venous access can be used if no hyperosmolar solutions (>800 mosm/L) or solutions with a high titration acidity or alkalinity are used. A peripheral venous catheter (PVC) can remain in situ for as long as it is clinically required unless there are signs of inflammation at the insertion site.

A peripherally inserted central catheter (PICC) is a useful option in providing secure venous access, which enables patients to be discharged earlier with the provision of home care. The objective was to identify the costs associated with having a PICC from a societal perspective, and to identify factors that are associated with total PICC costs. Data were obtained from a retrospective cohort of 469 hospitalized pediatric patients with PICCs inserted. Both direct and indirect costs were estimated from a societal perspective. Insertion costs, complication costs, nurse and physician assessment costs, inpatient ward costs, catheter removal costs, home care costs, travel costs, and the cost associated with productivity losses incurred by parents were included in this study. Based on catheter dwell time, the median total cost associated with a PICC per patient per day (including inpatient hospital costs) was $3,133.5 ($2,210.7-$9,627.0) in 2017 Canadian dollars ($1.00USD = $1.25CAD in 2017). The adjusted mean cost per patient per day was $2,648.2 ($2,402.4-$2,920.4). Excluding inpatient ward costs, the median total and adjusted costs per patient per day were $198.8 ($91.8-$2,475.8) and $362.7($341.0-$386.0), respectively. Younger age, occurrence of complications, more catheter dwell days, wards with more intensive care, and the absence of home care were significant factors associated with higher total PICC costs. This study has demonstrated the costs associated with PICCs. This information may be helpful for healthcare providers to understand PICC related cost in children and resource implications.

2012-01-01

Purpose: To evaluate the safety and feasibility of percutaneous stripping of totally implantable venous access devices (TIVAD) in case of catheter-related sleeve and to report a technique to free the catheter tip from vessel wall adherence. Materials and Methods: A total of 37 stripping procedures in 35 patients (14 men, 40%, and 21 women, 60%, mean age 53 ± 14 years) were reviewed. Totally implantable venous access devices were implanted because of malignancy in most cases (85.7%). Catheter-related sleeve was confirmed as cause of persistent catheter dysfunction despite instillation of thrombolytics. A technique to mobilize the catheter tip from the vessel wall was used when stripping with the snare catheter was impossible. Technical success, complication rate, and outcome were noted. Results: A total of 55.9% (n = 19) of the 34 technically successful procedures (91.9%) could be done with the snare catheter. In 15 cases (44.1%), additional maneuvers to free the TIVAD’s tip from the vessel wall were needed. Success rate was not significantly lower before (72.4%) than after (96.7%) implementation of the new technique (P = 0.09). No complications were observed. Follow-up was available in 67.6% of cases. Recurrent catheter dysfunction was found in 17 TIVADs (78.3%) at a mean of 137.7 days and a median of 105 days. Conclusions: Stripping of TIVADs is technically feasible and safe, with an overall success rate of 91.9%. Additional endovascular techniques to mobilize the distal catheter tip from the wall of the superior vena cava or right atrium to allow encircling the TIVAD tip with the snare catheter may be needed in 44.1% of cases.

To explore the relationship between the anatomical site of peripheral venous catheterization and risk of catheter-related phlebitis. Peripheral venous catheterization is frequently associated with phlebitis. Recent guidelines, recommend the use of an upper-extremity site for catheter insertion but no univocal consensus exists on the anatomical site with lower risk of phlebitis. Systematic review. We searched Medline (PubMed) and CINAHL (EBSCOhost) databases until the end of January 2017. We also reviewed the reference lists of retrieved articles and gray literature was excluded. Searches were limited to articles published in English with no restriction imposed to date of publication. The primary outcome was the incidence of phlebitis associated with anatomical site of peripheral catheterization. We included randomized controlled trials and observational studies on adult patients who required a peripheral catheter for the administration of medi- cation, intermittent or continuous fluid infusion. Antecubital fossa veins are associated with lower phlebitis rates, while hands veins are the most risky sites to develop phlebitis. There is no consensus regarding vein in forearm. Choosing the right anatomical site to insert a peripheral venous catheter is important to decrease phlebitis rate. Further studies should compare indwelling time in different anatomical sites with phlebitis rate. A more standardized approach in defining and assessing phlebitis among studies is recommended.

Full Text Available Cateteres venosos totalmente implantados são utilizados em pacientes com síndrome do intestino curto, para realizar o suporte nutricional parenteral, o qual mantém estes pacientes vivos, pois fornece-lhes nutrientes que são absorvidos pela via digestiva. No entanto, estes cateteres não são isentos de complicações. As infecções relacionadas aos cateteres venosos são as complicações mais temidas e sua incidência varia de 3% a 20%, aumentando em pacientes mais graves. O objetivo do presente estudo é descrever as complicações infecciosas em pacientes recebendo nutrição parenteral por meio de cateteres venosos totalmente implantados. Tais cateteres são utilizados pela Divisão de Nutrição Clínica do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo, para realizar o suporte nutricional parenteral em pacientes submetidos a ressecções extensas de intestino delgado. Foram avaliadas as complicações infecciosas ocorridas com 21 cateteres, implantados em 16 pacientes. O tempo de permanência dos cateteres foi de 768±664,3 dias (mediana 529 dias e a taxa de infecção foi de 0,029 infecções/paciente/ano, resultados que se comparam às taxas de infecção observadas em países desenvolvidos. Concluiu-se que os cuidados observados no manuseio destes cateteres foram de fundamental importância para diminuir a incidência de infecção nestes pacientes.Long-term venous catheters are used for the total parenteral nutrition infusion, which is essential for feeding short-bowel syndrome patients.

The central venous pressure (CVP) is the most commonly used static marker of preload for guiding fluid therapy in critically ill patients, though its usefulness remains controversial. Centrally inserted central catheters (CICCs) are the gold-standard devices for CVP monitoring but peripherally inserted central catheters (PICCs) may represent a valid alternative. We undertook a systematic review and meta-analysis with the aim to investigate whether the difference between PICC- and CICC-measured CVP is not significant. We searched for clinical studies published in PubMed and EMBASE databases from inception until December 21st 2016. We included studies providing data on paired and simultaneous CVP measurement from PICCs and CICCs. We conducted two analyses on the values of CVP, the first one according to the total number of CVP assessments, the second one considering the number of patients recruited. Four studies matched the inclusion criteria, but only three of them provided data for the meta-analyses. Both analyses showed non-significant differences between PICC-measured and CICC-measured CVP: 1489 paired simultaneous CVP assessments (MD 0.16, 95%CI -0.14, 0.45, p = 0.30) on a total of 57 patients (MD 0.22, 95%CI -1.46, 1.91, p = 0.80). Both analyses showed no heterogeneity (I2 = 0%). Available evidence supports that CVP monitoring with PICCs is accurate and reproduces similar values to those obtained from CICCs. The possibility to monitor CVP should not be used among clinical criteria for preferring a CICC over a PICC line.

The aim of this study is to evaluate the effectiveness and safety of percutaneously placed totally implantable venous-access ports (TIVAPs) of the forearm. Between January 2006 and October 2008, peripheral TIVAPs were implanted in 763 consecutive patients by ultrasound and fluoroscopic guidance. All catheters were implanted under local anesthesia and were tunneled subcutaneously. Indication, technical success, and complications were retrospectively analyzed according to Society of Interventional Radiology (SIR) criteria. Presence of antibiotic prophylaxis, periprocedurally administered drugs (e.g., sedation), and laboratory results at the time of implantation were analyzed. Maintenance during the service interval was evaluated. In total, 327,499 catheter-days were analyzed. Technical success rate was 99.3%. Reasons for initial failure of implantation were either unexpected thrombosis of the subclavian vein, expanding tumor mass of the mediastinum, or failure of peripheral venous access due to fragile vessels. Mean follow-up was 430 days. There were 115 complications observed (15.1%, 0.03 per 100 catheter-days), of which 33 (4.3%) were classified as early (within 30 days from implantation) and 82 (10.7%) as late. Catheter-related venous thrombosis was found in 65 (8.5%) of 763 (0.02 per 100 catheter-days) TIVAPs. Infections were observed in 41 (5.4%) of 763 (0.01 per 100 catheter-days) devices. Other complications observed included dislocation of the catheter tip (0.8%), occlusion (0.1%), or rupture (0.1%) of the port catheter. Dislocated catheters were corrected during a second interventional procedure. In conclusion, implantation of percutaneously placed peripheral TIVAPs shows a high technical success rate and low risk of early complications when ultrasound and fluoroscopic guidance are used. Late complications are observed three times as often as early complications.

The clinical evaluation of venous catheters for catheter-induced infections must conform to a strict biometric methodology. The statistical planning of the study (target population, design, degree of blinding), data management (database design, definition of variables, coding), quality assurance (data inspection at several levels) and the biometric evaluation of the Erlanger silver catheter project are described. The three-step data flow included: 1) primary data from the hospital, 2) relational database, 3) files accessible for statistical evaluation. Two different statistical models were compared: analyzing the first catheter only of a patient in the analysis (independent data) and analyzing several catheters from the same patient (dependent data) by means of the generalized estimating equations (GEE) method. The main result of the study was based on the comparison of both statistical models.

The controversy on chronic cerebrospinal venous insufficiency

Full Text Available The objective of this review is to analyze the actual scientific controversy on chronic cerebrospinal venous insufficiency (CCSVI and its association with both neurodegenerative disorders and multiple sclerosis (MS. We revised all published studies on prevalence of CCSVI in MS patients, including ultrasound and catheter venography series. Furthermore, we take into consideration other publications dealing with the pathophysiologic consequences of CCSVI in the brain, as well as ecent data characterizing the pathology of the venous wall in course of CCSVI. Finally, safety and pilot data on effectiveness of endovascular CCSVI treatment were further updated. Studies of prevalence show a big variability in prevalence of CCSVI in MS patients assessed by established ultrasonographic criteria. This could be related to high operator dependency of ultrasound. However, 12 studies, by the means of more objective catheter venography, show a prevalence >90% of CCSVI in MS. Global hypo-hypoperfusion of the brain, and reduced cerebral spinal fluid dynamics in MS was shown to be related to CCSVI. Postmortem studies and histology corroborate the 2009 International Union of Phlebology (UIP Consensus decision to insert CCSVI among venous malformations. Finally, safety of balloon angioplasty of the extracranial veins was certainly demonstrated, while prospective data on the potential effectiveness of endovascular treatment of CCSVI support to increase the level of evidence by proceeding with a randomized control trial (RCT. Taking into account the current epidemiological data, including studies on catheter venography, the autoptic findings, and the relationship between CCSVI and both hypo-perfusion and cerebro-spinal fluid flow, we conclude that CCSVI can be definitively inserted among the medical entities. Research is still inconclusive in elucidating the CCSVI role in the pathogenesis of neurological disorders. The controversy between the vascular and the

The aims of the study were to identify perceived barriers and facilitators to central venous catheter (CVC) insertion among healthcare providers and to understand the extent to which an existing Simulation-Based Mastery Learning (SBML) program may address barriers and leverage facilitators. Providers participating in a CVC insertion SBML train-the-trainer program, in addition to intensive care unit nurse managers, were purposively sampled from Veterans Administration Medical Centers located in geographically diverse areas. We conducted semistructured interviews to assess perceptions of barriers and facilitators to CVC insertion. Deidentified transcripts were analyzed using a grounded theory approach and the constant comparative method. We subsequently mapped identified barriers and facilitators to our SBML curriculum to determine whether or not the curriculum addresses these factors. We interviewed 28 providers at six Veterans Administration Medical Centers, identifying the following five overarching factors of perceived barriers to CVC insertion: (1) equipment, (2) personnel/staff, (3) setting or organizational context, (4) patient or provider, and (5) time-related barriers. Three overarching factors of facilitators emerged: (1) equipment, (2) personnel, and (3) setting or organizational context facilitators. The SBML curriculum seems to address most identified barriers, while leveraging many facilitators; building on the commonly identified facilitator of nursing staff contribution by expanding the curriculum to explicitly include nurse involvement could improve team efficiency and organizational culture of safety. Many identified facilitators (e.g., ability to use ultrasound, personnel confidence/competence) were also identified as barriers. Evidence-based SBML programs have the potential to amplify these facilitators while addressing the barriers by providing an opportunity to practice and master CVC insertion skills.

OBJECTIVE Neural interface technology may enable the development of novel therapies to treat neurological conditions, including motor prostheses for spinal cord injury. Intracranial neural interfaces currently require a craniotomy to achieve implantation and may result in chronic tissue inflammation. Novel approaches are required that achieve less invasive implantation methods while maintaining high spatial resolution. An endovascular stent electrode array avoids direct brain trauma and is able to record electrocorticography in local cortical tissue from within the venous vasculature. The motor area in sheep runs in a parasagittal plane immediately adjacent to the superior sagittal sinus (SSS). The authors aimed to develop a sheep model of cerebral venography that would enable validation of an endovascular neural interface. METHODS Cerebral catheter venography was performed in 39 consecutive sheep. Contrast-enhanced MRI of the brain was performed on 13 animals. Multiple telescoping coaxial catheter systems were assessed to determine the largest wide-bore delivery catheter that could be delivered into the anterior SSS. Measurements of SSS diameter and distance from the motor area were taken. The location of the motor area was determined in relation to lateral and superior projections of digital subtraction venography images and confirmed on MRI. RESULTS The venous pathway from the common jugular vein (7.4 mm) to the anterior SSS (1.2 mm) was technically challenging to selectively catheterize. The SSS coursed immediately adjacent to the motor cortex (SSS. Attempted access with 5-Fr and 6-Fr delivery catheters was associated with longer procedure times and higher complication rates. A 4-Fr catheter (internal lumen diameter 1.1 mm) was successful in accessing the SSS in 100% of cases with no associated complications. Complications included procedure-related venous dissection in two major areas: the torcular herophili, and the anterior formation of the SSS. The

Venous thrombo-embolic disease (VTE) is a potentially life threatening clinical event. Ankylosing spondylitis (AS) is a chronic inflammatory disease with a significantly increased risk of developing VTE. Management of acute proximal deep venous thrombosis (DVT) depends on the clinical status of the affected limb, extent of the thrombus and comorbidities of the patient. Semba and Dake introduced Catheter directed thrombolysis (CDT) to treat 21 patients of DVT in 1994. CDT is a life or limb sav...

Central venous catheters are widely used in critically ill patients; however, they are also associated with increased morbidity and mortality. The literature may underestimate the incidence of catheter-inducible right atrial thrombi that are asymptomatic but potentially life threatening. The recognized risk factors for its development include infections related to the catheter, endothelial injury secondary to mechanical and chemical damage induced by certain medications and infused fluids. The characteristics of the patient and the catheter, such as size, material, type, location and ease of insertion, as well as the duration of placement play an additional role. We report the case of a 38-year-old man, who developed an asymptomatic catheter-inducible right atrial thrombi requiring open heart surgery, after taking a central venous catheter for thirty-five days. The present case highlights existing limitations in making a correct and fast diagnosis, which should be anticipated in patients with multiple risk factors for thrombosis. Given the limited recommendations available, we consider that the most appropriate strategy should be individualized.

Autologous access is the best vascular access for dialysis also in older patients and it should be mature when patient needs hemodialysis. It is not always possible. Surgeon availability and demographic characteristics of patients (age, diabetes, vascular disease...) are factors that determine primary vascular access. To analyse outcome and vascular access complications in elderly who start hemodialysis without vascular access. All patients older than 75 years who initiated hemodialysis without vascular access between January 2000 and June 2002 were included, They were divided en two groups depending on primary vascular access. GI: arterio-venous fistulae. GIIl: Tunnelled cuffed catheter. Epidemiological and analytical data, vascular access complications related, as well as patient and first permanent vascular access survival from their inclusion in dialysis up to December 2002 were analysed and compared in both groups. 32 patients were studied. GI: n = 17 (4 men) and GIIl: n =1 5 (8 men), age: 79.9 +/- 3.8 and 81.7 +/- 4 years respectively (ns). There were no differences in sex and comorbidity (diabetes, ischemic heart disease, peripheral vascular disease and hypertension). It took GI 3 months to get a permanent vascular access suitable for using, while it took GIIl 1.3 months (p catheters was higher in GI (3.35 vs 1.87 p central venous thrombosis happen in GI (I: 25 CVT/100 patients-year) vs 30% in GIIl (I = 14.4/100 patients-year) (ns). No significant differences neither in bleeding (66.7% vs 33.3%) nor ischemia (75% vs 25%) were found. Dialysis dose (Kt/V) as well as anaemia degree were similar in both groups. Permanent vascular access survival after 2 years was 45.8% in GI and 24% in GII (ns). Patient survival was similar in GI and GII (72% vs 51% ns). Elderly who start hemodialysis without vascular access took longer to get a suitable permanent vascular access when arterio-venous fistulae is placed than with a tunnelled cuffed hemodialysis catheter.

Pharmacomechanical thrombolysis (PMT) and catheter-directed thrombolysis (CDT) are commonly used for the treatment of iliofemoral deep venous thrombosis (DVT). The purpose of this study was to examine the short- and long-term venous patency and venous valvular function as well as clinical outcomes of patients treated for iliofemoral DVT by PMT and CDT. A retrospective review of all patients with symptomatic DVT treated between 2006 and 2011 with PMT or CDT was performed. All patients were treated by local tissue plasminogen activator delivered with PMT or CDT. Patients were divided into two groups on the basis of initial treatment modality: patients treated by PMT alone (group 1), and those who underwent PMT and CDT or CDT alone (group 2). Group comorbidities, initial presenting symptoms, and Clinical, Etiologic, Anatomic, and Pathologic (CEAP) classification scores were compared. Postprocedural duplex ultrasound was used to assess valve function and treated vein patency rates. At all visits, Villalta and CEAP scores were recorded and compared. Group demographic and procedural results were analyzed by Fisher exact test for dichotomous variables and Kruskal-Wallis equality-of-populations rank test for the ordinal and continuous data. Kaplan-Meier survival estimates were used to assess preserved valve function as well as primary and secondary patency rates. There were 79 patients with 102 limbs treated for extensive iliofemoral DVT (median age, 51.5 years; range, 16.6-83.8 years). There were 18 patients in group 1 and 61 patients in group 2 (PMT + CDT [n = 54] or CDT alone [n = 7]). There were no differences in demographics or comorbidities between groups aside from malignant disease, which was more common in group 1 (35.3% vs 11.5%; P = .03). A total of 102 limbs were analyzed, 24 in group 1 and 78 in group 2. Patients in group 1 had a shorter symptom duration compared with group 2 (7 days vs 16 days; P = .011). The median number of procedures in group 1

It is widely assumed that central venous stenosis (CVS) is most commonly associated with previous central venous catheterization among the chronic hemodialysis (HD) patients. We evaluated the validity of this assumption in this retrospective study. The clinical records from 2,856 consecutive HD patients with vascular access failure during a 5-year period were reviewed, and a total of 26 patients with symptomatic CVS were identified. Combined with radiological findings, their clinical characteristics were examined. Only seven patients had a history of internal jugular dialysis catheterization. Diagnostic multidetector row computed tomography angiography showed that 7 of the 19 patients with no history of catheterization had left innominate vein stenosis due to extrinsic compression between the sternum and arch vessels. These patients had a shorter period from the time of creation of the vascular access to the initial referral (9.2 ± 7.6 months) than the rest of the patients (35.5 ± 18.6 months, p = 0.0017). Our findings suggest that cases without a history of central venous catheterization may not be rare among the HD patients with symptomatic CVS. However, those still need to be confirm by larger prospective studies of overall chronic HD patients with symptomatic CVS.

One of the recognised complications of catheter ablation is pulmonary venous stenosis. The aim of this study was to compare two methods of evaluation of pulmonary venous diameter for follow-up assessment of the above complication: (1) a linear approach evaluating two main diameters of the vein, (2) semiautomatically measured cross-sectional area (CSA). The study population consists of 29 patients. All subjects underwent contrast-enhanced magnetic resonance angiography (CeMRA) of the pulmonary veins (PVs) before and after the ablation; 14 patients were also scanned 3 months later. PV diameter was evaluated from two-dimensional multiplanar reconstructions by measuring either the linear diameter or CSA. A comparison between pulmonary venous CSA and linear measurements revealed a systematic difference in absolute values. This difference was not significant when comparing the relative change CSA and quadratic approximation using linear extents (linear approach). However, a trend towards over-estimation of calibre reduction was documented for the linear approach. Using CSA assessment, significant PV stenosis was found in ten PVs (8%) shortly after ablation. Less significant PV stenosis, ranging from 20 to 50% was documented in other 18 PVs (15%). CeMRA with CSA assessment of the PVs is suitable method for evaluation of PV diameters. (orig.)

IntroductionPreservation of venous access in children is a major concern in pediatric interventional radiology. If a peripherally inserted central catheter (PICC) breaks, there are two options: repair the line with a repair kit or exchange the line over a wire in the interventional suite. The purpose of this study is to assess the outcome of PICC repairs in children and to compare these with the outcomes of PICC exchange.Materials and MethodsThis is a single-center, retrospective study of central line-associated bloodstream infection (CLABSI) following management of externally broken PICCs (2010–2014). The occurrence of CLABSI within 30 days after repair (Group A) or exchange (Group B) of a line was analyzed, as well as PICCs exchanged following an initial and failed repair.ResultsA total of 235 PICC breaks were included in the study, of which 161 were repaired, and 116 of whom were successful (68%, Group A). No repair was performed in 74 PICCs—55/74 of these were exchanged over a wire (74%, Group B), and 19/74 lines were removed. The 30 days post-repair CLABSI rate (Group A) was 2.0 infections per 1000 catheter days, and the calculated risk was 4.3%. In comparison the 30 days post-exchange CLABSI rate (Group B) was 4.0 per 1000 catheter days and the calculated risk 10.9%. This difference was significant when adjusted for antibiotic use (OR 3.87; 95% CI 1.07–14.0, p = 0.039).ConclusionThe results of this study support repairing a broken PICC instead of removing or replacing the line.

Home parenteral nutrition (HPN) is a high-cost, complex nutrition support therapy that requires the use of central venous catheters. Central line-associated bloodstream infections (CLABSIs) are among the most serious risks of this therapy. Sustain: American Society for Parenteral and Enteral Nutrition's National Patient Registry for Nutrition Care (Sustain registry) provides the most current and comprehensive data for studying CLABSI among a national cohort of HPN patients in the United States. This is the first Sustain registry report detailing longitudinal data on CLABSI among HPN patients. To describe CLABSI rates for HPN patients followed in the Sustain registry from 2011-2014. Descriptive, χ 2 , and t tests were used to analyze data from the Sustain registry. Of the 1,046 HPN patients from 29 sites across the United States, 112 (10.7%) experienced 194 CLABSI events during 223,493 days of HPN exposure, for an overall CLABSI rate of 0.87 episodes/1,000 parenteral nutrition-days. Although the majority of patients were female (59%), adult (87%), white (75%), and with private insurance or Medicare (69%), CLABSI episodes per 1,000 parenteral nutrition-days were higher for men (0.69 vs 0.38), children (1.17 vs 0.35), blacks (0.91 vs 0.41), and Medicaid recipients (1.0 vs 0.38 or 0.39). Patients with implanted ports or double-lumen catheters also had more CLABSIs than those with peripherally inserted or central catheters or single-lumen catheters. Staphylococci were the most commonly reported pathogens. These data support findings of smaller studies about CLABSI risk for children and by catheter type and identify new potential risk factors, including gender, race, and insurance type. Additional studies are needed to determine effective interventions that will reduce HPN-associated CLABSI. Copyright © 2016 Association for Professionals in Infection Control and Epidemiology, Inc.

Traditional practice after vaginal hysterectomy was to keep the vaginal pack and urinary catheter for 24 hours post operatively. But there were studies that prolonged cathterisation was associated with urinary infection. So this study was conducted to compare the post operative outcome when the urinary catheter and vaginal pack were removed after 3 hours and after 24 hours after surgery. The study was done in the Department of Obstetrics and Gynecology, in a tertiary teaching institute of South India from September 2008 to March 2010. It was a randomised controlled trial involving 200 women undergoing vaginal surgery, who were randomly assigned to 2 groups - catheter and vaginal pack were removed either in 3 h in study group or were removed in 24 h in control group. The outcome of the study were vaginal bleeding, urinary retention, febrile morbidity, and urinary infection. There was no significant difference between the study and control groups with respect to vaginal bleeding (0 and 1%, p = 1), urinary retention (9 and 4%, p = 0.15), febrile morbidity (7 and 4%, p = 0.35), and urinary infection (26% in each group, p = 1.0). Keeping the urinary catheter and vaginal pack for 24 h following vaginal surgery does not offer any additional benefit against removing them after 3 h.

Objective: To investigate the feasibility and efficacy of trans-jugular catheter-directed thrombolysis (CDT) together with trans-dorsalis pedis vein thrombolysis for the treatment of deep venous thrombosis (DVT) of the lower limbs. Methods: Jugular vein puncture, indwelling catheter and placement of IVC filter were performed in 18 patients with DVT (study group) followed by continuous trans-jugular CDT together with trans-dorsalis pedis vein thrombolysis. During the corresponding period, 16 patients with DVT (control group) received trans-dorsalis pedis vein thrombolysis only. Results: The thrombolytic time and total dose of urokinase in study group and control group were (6.6 ± 2.3) days, (5.52 ± 2.24) x 106 units and (8.2 ± 1.4) days, (7.00 ± 1.66) x 106 units respectively. The thrombolytic time and total dose of urokinase in study group were significantly lower than that in control group (P < 0.05). After the treatment the thigh circumference and calf circumference in study group showed a reduction of (4.6 ± 2.1) cm and (4.0 ± 2.1) cm respectively, which were (3.2 ± 1.7) cm and (2.7 ± 1.5) cm respectively in control group, the difference between two groups was statistically significant (P < 0.05). The complete patent of the veins was 66.7% in study group and 31.3% in control group, the difference between two groups was significant (P < 0.05). In four cases of the study group, the filters were withdrawn through the original puncture site after the thrombus was completely dissolved. Conclusion: Trans-jugular CDT combined with trans-dorsalis pedis vein thrombolysis is an effective and safe therapeutic technique for the treatment of deep venous thrombosis of the lower extremities, moreover, the filter can be taken back via the original puncture site when the thrombus is completely dissolved.

2003-01-01

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

PurposeThe aim of this retrospective study was to analyze the long-term outcome of peripherally implanted venous access ports in the forearm at our institution in a female patient collective.MethodsBetween June 2002 and May 2011, a total of 293 female patients with an underlying malignancy had 299 forearm ports implanted in our interventional radiology suite. The mean age of the cohort was 55 ± 12 years (range 26–81 years). The majority of women suffered from breast (59.5 %) or ovarian cancer (28.1 %). Complications were classified as infectious complications, thrombotic and nonthrombotic catheter dysfunction (dislocation of the catheter or port chamber, fracture with/without embolization or kinking of the catheter, port occlusion), and others.ResultsWe analyzed a total of 90,276 catheter days in 248 port systems (47 patients were lost to follow-up). The mean device service interval was 364 days per catheter (range 8–2,132, median 223 days, CI 311–415, SD 404). Sixty-seven early (≤30 days from implantation) or late complications (>30 days) occurred during the observation period (0.74/1,000 catheter days). Common complications were port infection (0.18/1,000 days), thrombotic dysfunction (0.12/1,000 days), and skin dehiscence (0.12/1,000 days). Nonthrombotic dysfunction occurred in a total of 21 cases (0.23/1,000 days) and seemed to cumulate on the venous catheter entry site on the distal upper arm.ConclusionPeripherally implanted venous access ports in the forearm are a safe alternative to chest or upper-arm ports in female oncology patients. Special attention should be paid to signs of skin dehiscence and nonthrombotic dysfunction, especially when used for long-term treatment.

Venous thromboembolism (VTE) is a complication that frequently occurs in patients with neoplastic diseases. Several models have therefore been developed to identify patient subgroups diagnosed with cancer who are at increased risk of developing VTE. The most common forms of thromboembolic episodes are deep vein thrombosis in the lower limbs and pulmonary thromboembolism. However, venous thrombosis is also diagnosed in atypical locations. There are few revisions of unusual cases of venous thrombosis. In most cases, VTE occurs in the upper limbs and in the presence of central venous catheters, pacemakers and defibrillators. We present the case of a patient diagnosed with breast cancer and treated with surgery, chemotherapy and radiation therapy who developed a thrombosis in the upper limbs (brachial and axillary).

Nursing students should be given opportunities to participate in clinical audits during their education. However, audit tools are seldom tested for reliability among nursing students. The aim of this study was to present reliability among nursing students using the instrument PVC assess to assess management of peripheral venous catheters (PVCs) and PVC-related signs of thrombophlebitis. PVC assess was used to assess 67 inserted PVCs in 60 patients at ten wards at a university hospital. One group of nursing students (n=4) assessed PVCs at the bedside (inter-rater reliability) and photographs of these PVCs were taken. Another group of students (n=3) assessed the PVCs in the photographs after 4 weeks (test-retest reliability). To determine reliability, proportion of agreement [P(A)] and Cohen's kappa coefficient (κ) were calculated. For bedside assessment of PVCs, P(A) ranged from good to excellent (0.80-1.0) in 55% of the 26 PVC assess items that were tested. P(A) was poor (satisfactory reliability among nursing students. However, students need training in how to use the instrument before assessing PVCs.

Mishkin, G J

2007-01-01

More than 20% of the world's population use a catheter for dialysis, despite guidelines limiting their use. Although the structure and design of the catheters differ by manufacturer, the material used in central venous catheters and peritoneal dialysis catheters are the same across manufacturers. Given the long-term use of these catheters in the dialysis population, the good compatibility of the antiseptics and disinfectants used on the catheters is imperative to prevent failure and cracking of the catheter material. Tensile strengths of commercially available catheters were measured after exposure to commonly used disinfectants. The tensile strength was then compared between the catheters by analyzing the displacement vs. force (N) curves produced during the evaluation. A total of 44 catheter lumens were evaluated. The electrolytically produced sodium hypochlorite solution, Alcavis 50/ExSept Plus, was the only solution shown to be compatible with all three catheter materials resulting in a deviation of less than 10% for each of the different catheter types. Electrolytically produced sodium hypochlorite solutions were the only solutions in this study that did not alter the physical properties of any of the catheters after long-term exposure.

to investigate the incidence of phlebitis and its association with risk factors when using peripheral IV catheters (PIC) and following their removal - (post-infusion phlebitis) in hospitalized adults. a cohort study of 171 patients using PIC, totaling 361 punctures. Sociodemographic variables and variables associated with the catheter were collected. Descriptive and analytical statistical analyses were performed. average patient age was 56.96 and 51.5% of the sample population was male. The incidence of phlebitis was 1.25% while using PIC, and 1.38% post-infusion. The incidence of phlebitis while using PIC was associated with the length of time the catheter remained in place, whereas post-infusion phlebitis was associated with puncture in the forearm. Ceftriaxone, Clarithromycin and Oxacillin are associated with post-infusion phlebitis. this study made it possible to investigate the association between risk factors and phlebitis during catheter use and following its removal. The frequency of post-infusion phlebitis was larger than the incidence of phlebitis with the catheter in place, with Phlebitis Grade III and II being the most frequently found in each of these situations, respectively. Aspects related to post-infusion phlebitis can be explained, given the limited number of studies addressing this theme from this perspective. investigar a incidência de flebites e a associação de fatores de risco com a sua ocorrência durante o uso e após a retirada do cateter intravenoso periférico - CIP (Flebite pós-infusão) em adultos hospitalizados. estudo de coorte com 171 pacientes com CIP, totalizando 361 punções.

Full Text Available Introduction: Chronic catheter infection usually involves external Dacron cuff colonization, without its removal, antibiotic treatment proved ineffective. Catheter unroofing technique has been described as an alternative to peritoneal catheter removal. Material and methods: We analyzed the data from 13 patients retrospectively. Evolution after unroofing was evaluated, considering as treatment failure the appearance of new infection in the hole, tunnel or peritonitis associated to the same germ. Results: Between 1997-2014 years, unroofing was performed on 13 patients. Mean age-rate: 46.2 (IC 95%: 35.9 years – 56.5 years male sex 9, 69.23%. Germs: staphylococcus 7, pseudomona 2, polymicrobial 1, negative culture 3. Nine patiens healed: 69.2%; there was no statistical association among sex, age, microbiological result, previous hemodialysis use, type of catheter, surgical technique or with the surgeon who performed the procedure (p≥ 0.05. Discussion: Catheter removal implies transient transference to hemodialysis and new replacement surgery, although there is few experience with this technique, it could be an acceptable alternative, enabling a group of patients to continue with PD treatment. Conclusion: Unroofing technique proved to be beneficial in 69.2% of the cases (9 patients independently of the type of germ present, representing an acceptable treatment which avoids catheter removal, enabling the procedure to continue, and decreasing the need to employ more aggressive therapies.

Catheter-associated urinary tract infections (CAUTI) are costly, common and often preventable by reducing unnecessary urinary catheter (UC) use. To summarise interventions to reduce UC use and CAUTIs, we updated a prior systematic review (through October 2012), and a meta-analysis regarding interventions prompting UC removal by reminders or stop orders. A narrative review summarises other CAUTI prevention strategies including aseptic insertion, catheter maintenance, antimicrobial UCs, and bladder bundle implementation. 30 studies were identified and summarised with interventions to prompt removal of UCs, with potential for inclusion in the meta-analyses. By meta-analysis (11 studies), the rate of CAUTI (episodes per 1000 catheter-days) was reduced by 53% (rate ratio 0.47; 95% CI 0.30 to 0.64, pSMD) in catheterisation duration (days) was -1.06 overall (p=0.065) including a statistically significant decrease in stop-order studies (SMD -0.37; pSMD, -1.54; p=0.071). No significant harm from catheter removal strategies is supported. Limited research is available regarding the impact of UC insertion and maintenance technique. A recent randomised controlled trial indicates antimicrobial catheters provide no significant benefit in preventing symptomatic CAUTIs. UC reminders and stop orders appear to reduce CAUTI rates and should be used to improve patient safety. Several evidence-based guidelines have evaluated CAUTI preventive strategies as well as emerging evidence regarding intervention bundles. Implementation strategies are important because reducing UC use involves changing well-established habits.

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

The totally implantable venous access port plays a crucial role in delivering chemotherapy in the outpatient setting. Here, we report the first case of a patient with hypopharyngeal tumor who developed chest wall metastasis over the totally implantable venous access port inserted in the internal jugular vein. Our patient, a 58-year-old man with a hypopharyngeal tumor presented with a lump over the totally implantable venous access port site. The port was removed and the lump was biopsied. The CT studies showed that the tumor had spread along the catheter from the hypopharynx to the chest wall. The pathology from the biopsy showed squamous cell carcinoma (SCC). The patient had poor performance status and opted for hospice care. We present a novel case of metastasis over the totally implantable venous access port implanted in a patient with a hypopharyngeal tumor. We also reviewed relevant literature comparing the data from percutaneous endoscopic gastrostomy (PEG) tube site metastasis with our patient and other similar case reports. © 2017 Wiley Periodicals, Inc.

Venous chest anatomy: clinical implications

International Nuclear Information System (INIS)

Chasen, M.H.; Charnsangavej, C.

1998-01-01

This article provides a practical approach to the clinical implications and importance of understanding the collateral venous anatomy of the thorax. Routine radiography, conventional venography, computed tomography (CT), and magnetic resonance (MR) imaging studies provide correlative anatomic models for the demonstration of how interconnecting collateral vascular networks within the thorax maintain venous stability at all times. Five major systems comprise the collateral venous network of the thorax ( Fig. 1 ). These include the paravertebral, azygos-hemiazygos, internal mammary, lateral thoracic, and anterior jugular venous systems (AJVS). The five systems are presented in the following sequence: (a) a brief introduction to the importance of catheter position and malposition in understanding access to the thoracic venous system, (b) the anatomy of the azygos-hemiazygos systems and their relationship with the paravertebral plexus, (c) the importance of the AJVS, (d) 'loop' concepts interconnecting the internal mammary and azygos-hemiazygos systems by means of the lateral thoracic and intercostal veins, and (e) the interconnecting venous networks on the thoracic side of the thoracoabdominal junction. Certain aspects of the venous anatomy of the thorax will not be discussed in this chapter and include (a) the intra-abdominal anastomoses between the superior and inferior vena cavae (IVC) via the internal mammary, lateral thoracic, and azygos-hemiazygos systems (beyond the scope of this article), (b) potential collateral vessels involving vertebral, parascapular, thyroidal, thymic, and other smaller veins that might anastomose with the major systems, and (c) anatomic variants and pitfalls that may mimic pathologic conditions (space limitations).

2015-01-01

The present work aimed to study the use of ionizing radiation for coating of silver nanoparticles on central polyurethane catheters, providing reduction of infections associated with contamination of catheters introduced into the bloodstream. Silver nanoparticles have physical, chemical and biological properties only when compared to metal on a macroscopic scale, and have been used in the medical field because of its remarkable antimicrobial activity. Titanium dioxide nanoparticles obtained by the sol gel method were used as the coating catheters for subsequent impregnation of silver nanoparticles with ionizing radiation at doses of 25 and 50 kGy. A Raman spectrometry was used to identify the polymorph of titanium oxide, rutile. In trials with (ICP OES) were evaluated amounts of titanium and silver coated catheters in titanium oxide and silver.(author)

While non-invasive ventilation aimed at avoiding intubation has become the modality of choice to treat mild to moderate acute respiratory acidosis, many severely acidotic patients (pH respiratory acidosis was only feasible when blood flow rates of 750 to 1000 mL/minute (19Fr catheter) were used. Maximal CO2-elimination was 146.1 ± 22.6 mL/minute, while pH increased from 7.13 ± 0.08 to 7.41 ± 0.07 (blood flow of 1000 mL/minute; sweep gas flow 16 L/minute). Accordingly, a sweep gas flow of 8 L/minute resulted in a maximal CO2-elimination rate of 138.0 ± 16.9 mL/minute. The 14.5Fr catheter allowed a maximum CO2 elimination rate of 77.9 mL/minute, which did not result in the normalization of pH. Veno-venous ECCO2R may serve as a treatment option for severe respiratory acidosis. In this porcine model, ECCO2R was most effective when using blood flow rates ranging between 750 and 1000 mL/minute, while an increase in sweep gas flow from 8 to 16 L/minute had less impact on ECCO2R in this setting.

2015-01-01

Full Text Available Background: Chemoport is an essential part of the management of children with cancer and provides long-term venous access. There are few studies from resource poor countries reporting complications of chemoport. Aims: This study was aimed at describing the complications of chemoport in patients with cancer. Materials and Methods: This retrospective observational study analyzed 200 patients <15 years of age who underwent chemoport insertion. The medical records of these patients were reviewed for the patient characteristics, diagnosis, nature of port use, port-related complications and their management. Results: A total of 209 ports were implanted in 200 patients and 24 ports were removed due to port-related complications. There were 122 boys and 78 girls whose ages ranged from 4 months to 13 years (median age 2.5 years. About72% of patients were <2 years old. The cumulative duration of catheterization was 54,100 days. Of 209 ports, there were 36 complications that led to the removal of 21 ports. Port-related infection was the most common infection observed in our study (0.66/1000 catheter days and 11.9%. Mechanical complications were seen in 9 patients. Venous thrombosis and skin necrosis occurred in one patient each. Conclusions: Use of chemoport is safe and is a boon for children with cancer in developing countries with incidence of complications similar to Western countries. Although use of chemoport is associated with complications, they are easily managed. With stringent catheter care by trained personnel, some complications can be prevented.

We assessed the potential impact of infusion tubing on blood glucose imbalance in ICU patients given intensive insulin therapy (IIT). We compared the incidence of blood glucose imbalance in patients equipped, in a nonrandomized fashion, with either conventional tubing or with a multiport infusion device. We retrospectively analyzed the nursing files of 35 patients given IIT through the distal line of a double-lumen central venous catheter. A total of 1389 hours of IIT were analyzed for occurrence of hypoglycemic events [defined as arterial blood glucose below 90 mg/dL requiring discontinuation of insulin]. Twenty-one hypoglycemic events were noted (density of incidence 15 for 1000 hours of ITT). In 17 of these 21 events (81%), medication had been administered during the previous hour through the line connected to the distal lumen of the catheter. Conventional tubing use was associated with a higher density of incidence of hypoglycemic events than multiport infusion device use (23 vs. 2 for 1,000 hours of IIT; rate ratio = 11.5; 95% confidence interval, 2.71-48.8; p tubing carrying other medications can lead to the delivery of significant amounts of unscheduled products. Hypoglycaemia observed during IIT could be related to this phenomenon. The use of a multiport infusion device with a limited dead volume could limit hypoglycemia in patients on IIT.

Peripheral venous catheters (PVCs) can be associated with serious infectious complications. We evaluated the effect of education and feedback on process measures to improve PVC care and infectious complications. Quasi-experimental controlled crossover study with sampling before and after education. An 804-bed tertiary care teaching hospital. Nurses and patients in 10 non-intensive care units. We implemented a process to improve PVC care in 10 non-intensive care units. The 4 periods (each 3 months in duration) included a preintervention period and a staggered educational intervention among nurses. During intervention period 1, 5 units participated in the intervention (group A), and 5 units served as a control group (group B). Group B underwent the intervention during intervention period 2, and both groups A and B received feedback on performance during intervention period 3. Process measures were evaluated twice monthly, and feedback was given to nurses directly and to the unit manager on a monthly basis. During the preintervention period, there were no significant differences between groups A and B. Of 4,904 intravascular catheters evaluated, 4,434 (90.4%) were peripheral. By the end of the study, there were significant improvements in processes, compared with the preintervention period, including accurate documentation of dressing (from 442 cases [38%] to 718 cases [59%]; P feedback to nurses increases and sustains compliance with processes to reduce the risk of infection from PVCs.

To evaluate visualization of the right adrenal vein (RAV) with multidetector CT and non-contrast-enhanced MR imaging in patients with primary aldosteronism. A total of 125 patients (67 men) scheduled for adrenal venous sampling (AVS) were included. Dynamic 64-detector-row CT and balanced steady-state free precession-based non-contrast-enhanced 3-T MR imaging were performed. RAV visualization based on a four-point score was documented. Both anatomical location and variation on cross-sectional imaging were evaluated, and the findings were compared with catheter venography as the gold standard. The RAV was visualized in 93.2 % by CT and 84.8 % by MR imaging (p = 0.02). Positive predictive values of RAV visualization were 100 % for CT and 95.2 % for MR imaging. Imaging score was significantly higher in CT than MR imaging (p < 0.01). The RAV formed a common trunk with an accessory hepatic vein in 16 % of patients. The RAV orifice level on cross-sectional imaging was concordant with catheter venography within the range of 1/3 vertebral height in >70 % of subjects. Success rate of AVS was 99.2 %. Dynamic CT is a reliable way to map the RAV prior to AVS. Non-contrast-enhanced MR imaging is an alternative when there is a risk of complication from contrast media or radiation exposure. (orig.)

to evaluate the use of peripheral venous catheters based on microbiological analysis of devices (dressing and three-way stopcocks) and thus contribute to the prevention and infection control. this was a prospective study of microbiological analysis of 30 three-way stopcocks (external surfaces and lumens) and 30 dressing used in maintaining the peripheral venous catheters of hospitalized adult patients. all external surfaces, 40% of lumens, and 86.7% of dressing presented bacterial growth. The main species isolated in the lumen were 50% coagulase-negative Staphylococcus, 14.3% Staphylococcus aureus, and 14.3% Pseudomonas aeruginosa. Fifty nine percent of multidrug-resistant bacteria were isolated of the three-way stopcocks, 42% of the lumens, and 44% of the dressing with a predominance of coagulase-negative Staphylococcus resistant to methicillin. Besides, 18% gram-negative bacteria with resistance to carbapenems were identified from multidrug-resistant bacteria on the external surfaces of the three-way stopcocks. it is important to emphasize the isolation of coagulase-negative Staphylococcus and gram-negative bacteria resistant to methicillin and carbapenems in samples of devices, respectively, which reinforces the importance of nursing care in the maintenance of the biologically safe environment as well as prevention and infection control practices. avaliar o uso de cateteres venosos periféricos com base em análises microbiológicas de dispositivos (curativos e torneiras de três vias - T3Vs) e assim contribuir para a prevenção e controle de infecção. estudo prospectivo de análise microbiológica de 30 T3Vs (superfícies externas e lúmens) e 30 curativos utilizados na manutenção dos cateteres venosos periféricos de pacientes adultos hospitalizados. todas as superfícies externas, 40% dos lúmens e 86,7% dos curativos apresentaram crescimento bacteriano.

Full Text Available Several severe complications may be associated with the use of central venous catheters (CVC. We retrospectively evaluated on a large cohort of patients the incidence of CVC-related early and late complications. From 7/99 to 12/2005, 1102 CVC have been implanted at our Institution in 881 patients with haematological malignancies (142,202 total day number of implanted CVC. Early mechanic complications were 79 (7.2% - 0.55/1,000 days/CVC. Thirty-nine episodes of early infective complications (<1 week from CVC implant occurred (3.5% - 0.3/1000 days/CVC: furthermore, 187 episodes of CVC-related sepsis (17% - 1.3/1000 days/CVC were recorded. There were 29 episodes (2.6% of symptomatic CVC-related thrombotic complications, with a median interval from CVC implant of 60 days (range 7 – 395. The rate of CVC withdrawal due to CVC-related complications was 26%. The incidence of CVC-related complications in our series is in the range reported in the literature, notwithstanding cytopenia often coexisting in haematological patients.

Prolonged catheterization is the primary risk factor for catheter-associated urinary tract infection (CAUTI). Reminder systems are interventions used to prompt the removal of unnecessary urinary catheters. To summarize the effect of urinary catheter reminder systems on the rate of CAUTI, urinary catheter use, and the need for recatheterization, we performed a systematic review and meta-analysis. Studies were identified in MEDLINE, the Cochrane Library, Biosis, the Web of Science, EMBASE, and CINAHL through August 2008. Only interventional studies that used reminders to physicians or nurses that a urinary catheter was in use or stop orders to prompt catheter removal in hospitalized adults were included. A total of 6679 citations were identified; 118 articles were reviewed, and 14 articles met the selection criteria. The rate of CAUTI (episodes per 1000 catheter-days) was reduced by 52% (P SMD) in the duration of catheterization was -1.11 overall (P = 070), including a statistically significant decrease in studies that used a stop order (SMD, -0.30; P = .001) but not in those that used a reminder (SMD, -1.54; P = .071). Recatheterization rates were similar in control and intervention groups. Urinary catheter reminders and stop orders appear to reduce the rate of CAUTI and should be strongly considered to enhance the safety of hospitalized patients.

For chronic subdural hematoma, placement of a Blake drain with a two-burr-hole craniotomy is often preferred. However, the placement of such drains carries the risk of penetrating the brain surface or damaging superficial venous structures. To describe the use of a Nelaton catheter for the placement of a subdural drain in two-burr-hole trephination for chronic subdural hematoma. A Nelaton catheter was used to guide placement of a Blake drain into the subdural hematoma cavity and provide irrigation of the hematoma cavity. With the two-burr-hole method, the Nelaton catheter could be removed easily via the frontal burr hole after the Blake drain was in place. We used the Nelaton catheters in many surgical procedures and found it a safe and easy technique. This method allows the surgeon to safely direct the catheter into the correct position in the subdural space. This tool has two advantages. First, the use of a small and flexible Nelaton catheter is a safe method for irrigation of a chronic subdural hematoma cavity. Second, in comparison with insertion of subdural drainage alone through a burr hole, the placement of the Nelaton catheter in subdural space is easier and the risk of damaging relevant structures such as cortical tissue or bridging veins is lower. Thus this technique may help to avoid complications when placing a subdural drain. Georg Thieme Verlag KG Stuttgart · New York.

Peripheral intravenous catheters (PIVCs) are frequently removed due to phlebitis. We hypothesized that catheters made of polyurethane, which is more flexible than Teflon, would decrease phlebitis, and that flexibility could be estimated by measuring the catheter-tip angle. Ultrasonography in two groups of patients with different catheter types was then used to compare catheter-tip angles and phlebitis. Observational studies were carried out at a medical ward in a university hospital. Infusion therapy was administered to one group of patients in 2014 using Teflon catheters (control group, n = 200), and to another group of patients in 2015 using polyurethane catheters (investigational group, n = 207). The symptoms were assessed according to a scale developed by the Infusion Nurses Society. Long-axis ultrasonography images taken immediately before catheter removal were used to measure the angle between the central line of the catheter within 2 mm from the distal point and a tangent to the vessel wall. There were no significant differences between the two groups with respect to sex, age, and medical diagnosis. In the control and investigational groups, the rates of phlebitis were 37% (73/200) and 17% (36/207), respectively (pPhlebitis occurred more frequently when the catheter-tip was placed at angle >5.8°. The frequency of phlebitis was lower in the polyurethane, in which the catheter was placed at lower angle, almost parallel to the vessel. Our results will aid in developing new catheters and in improving PIVC-securement techniques.

Catheter ablation of epicardial ventricular tachycardia

Directory of Open Access Journals (Sweden)

Takumi Yamada, MD, PhD

2014-08-01

Full Text Available Ventricular tachycardias (VTs can usually be treated by endocardial catheter ablation. However, some VTs can arise from the epicardial surface, and their substrate can be altered only by epicardial catheter ablation. There are two approaches to epicardial catheter ablation: transvenous and transthoracic. The transvenous approach through the coronary venous system (CVS has been commonly used because it is easily accessible. However, this approach may be limited by the distribution of the CVS and insufficient radiofrequency energy delivery. Transthoracic epicardial catheter ablation has been developed to overcome these limitations of the transvenous approach. It is a useful supplemental or even preferred strategy to eliminate epicardial VTs in the electrophysiology laboratory. This technique has been applied for scar-related VTs secondary to often non-ischemic cardiomyopathy and sometimes ischemic cardiomyopathy, and idiopathic VTs as the epicardial substrates of these VTs have become increasingly recognized. When endocardial ablation and epicardial ablation through the CVS are unsuccessful, transthoracic epicardial ablation should be the next option. Intrapericardial access is usually obtained through a subxiphoidal pericardial puncture. This approach might not be possible in patients with pericardial adhesions caused by prior cardiac surgery or pericarditis. In such cases, a hybrid procedure involving surgical access with a subxiphoid pericardial window and a limited anterior or lateral thoracotomy might be a feasible and safe method of performing an epicardial catheter ablation in the electrophysiology laboratory. Potential complications associated with this technique include bleeding and collateral damage to the coronary arteries and phrenic nerve. Although the risk of these complications is low, electrophysiologists who attempt epicardial catheter ablation should know the complications associated with this technique, how to minimize their

The insertion of central venous catheters (CVCs) is an integral part of the management of critically ill patients. We aimed to study the impact of ultrasonography (USG) on CVC insertion in intensive care. A prospective study of 450 patients requiring CVC in the intensive care unit (ICU) of a tertiary care hospital. The patients were randomized into two groups: to have CVC insertion with USG-guidance or with the anatomic landmark technique (ALT). Data were collected on patient demographics; operator experience; and method, site and side of insertion. Outcome measures included successful insertion of CVC, number of attempts needed and complications. Internal jugular vein (IJV) cannulation was successful in 177/194 patients (91.2%) using ALT and in 200/205 patients (97.6%) using USG guidance, a significant difference of 6.4% (P = 0.006). Using ALT, 72.7% of cannulations could be accomplished in the first attempt as compared with 84.4% with USG guidance (P = 0.004). The overall complication rate was 28/399 (7%), with 19 (9.8%) complications in the ALT group and 9 (4.4%) in the USG group (age-, sex-, and operator-adjusted OR = 0.35, 95% CI: 0.13–0.96; P = 0.03). For subclavian vein catheterization, the success rate was 26/28 (92.9%) in the ALT group and 17/17 (100%) in the USG group (P = 0.52). Using ALT, 71.4% cannulation could be accomplished in the first attempt as compared with 82.4% under USG guidance (P = 0.49). The overall complication rate was 6/45 (13.3%), with 4 (14.3%) complications in the ALT group and 2 (11.8%) in the USG group (P > 0.99). Real-time USG guidance improves success rates, reduces the number of attempts and decreases the complications associated with CVC insertion, especially for the IJV, and should become the standard of care in intensive care

Objective: to observe the effectiveness of head-ring type posture pad used for prone position in performing the procedure of peripheral insertion of central catheter (PICC) via the dorsal forearm vein in patients with neoplasm. Methods: A total of 80 consecutive tumor patients were randomly divided into two groups. PICC was carried out in all patients in prone position. In control group (n=38) PICC was performed with patient's head inclining to one side, while in study group (n=42) PICC was performed with the help of head-ring type pad to keep the patient in comfortable posture. The comfortableness, breathing rhythm, transcutaneous oxygen saturation and the change of heart rate during the procedure were observed. The results were analyzed and compared between the two groups. Results: The results is study group were much better than those in control group. Statistically significant difference in the comfortableness, breathing rhythm, transcutaneous oxygen saturation and heart rate existed between the two groups. Conclusion: The head-ring type posture pad used for prone position can make the patients more comfortable in performing peripheral insertion of central venous catheter via the dorsal forearm vein.

2014-01-01

Objective: To look for survival rate and major reasons behind the failure of tunnelled dialysis catheters in patients on haemodialysis. Methods: The retrospective study was conducted at the Department of Interventional Radiology, Shifa International Hospital, Islamabad, and comprised records of 100 consecutive subjects from a list of patients in whom tunnelled cuffed catheters were placed from February 2009 to January 2011 and were followed up for two years. Data was collected on a proforma from the hospital database and medical records of patients. SPSS 19 was used for statistical analysis. Results: Of the total 122 catheters placed in 100 patients, 49(40.16%) were lost to follow-up. Of the remaining 73(59.83%) catheters, 38(52%) had achieved their desired function, while 35(48%) failed to achieve the target duration. Among the reasons of catheter failure, infection was the commonest at 13(37.14%) with infection rate of 0.24 per 1000 catheter days. According to Kaplan Meier analysis, catheter survival rates at 60, 90 and 180 days were 89%, 77% and 64% respectively. Mean effective duration of catheter was 129+-117 days. Conclusion: Tunnelled dialysis catheters can be safely used as vascular access till the maturation of fistula and may be an alternative to Arterio-Venous Fistula or graft for long-term vascular access if indicated.

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.

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.

The aim of the study was to retrospectively evaluate the incidence and outcomes of inferior vena cava (IVC) filter thrombus during catheter-directed thrombolysis (CDT) for acute proximal deep venous thrombosis (DVT). From October 2006 to June 2015, patients diagnosed with acute proximal DVT and received CDT after a retrievable IVC filter was placed were included. The incidence, treatment, and outcomes of IVC filter thrombus during CDT were recorded and analyzed. A total of 189 patients (91 women, 98 men; mean age, 57.6 ± 9.8 years; range, 24-85 years) were included in this study. Among the 189 cases, the DVTs involved popliteal iliofemoral veins in 54 patients, iliofemoral veins in 113 patients, and iliac veins in 22 patients, of which 18 patients had thrombus extended into the IVC. Of the 189 patients, a total of 8 (4.2%, 8 of 189) patients were identified with IVC filter thrombus during CDT. The IVC filter thrombus was detected on a median of 2 days (range, 2-4 days) of CDT therapy, including small-size (n = 6) and large-size (n = 2) filter thrombus. Of the 8 patients, CDTs were performed with a mean 7.6 ± 1.1 days (range, 6-11 days) after the presence of symptoms for the treatment of proximal DVT, and all the IVC filter thrombi were lysed during CDT for the proximal DVT. All the IVC filters were removed successfully with a mean of 12.8 ± 0.93 days from placement. There were no procedure- or thrombolysis-related major complications, and no symptomatic pulmonary embolism breakthrough was seen in any of the patients after the filter placement. IVC filter thrombus during CDT for the acute proximal DVT is uncommon, and all of them did not need any additional treatment. Copyright © 2016 Elsevier Inc. All rights reserved.

CRBSI occurred at a rate of 0.85 vs. 0.28 per 1000 catheter days in the heparin vs ethanol group by intention to treat analysis (incident rate ratio (IRR for ethanol vs. heparin 0.17; 95%CI 0.02-1.63; p=0.12. Flow issues requiring catheter removal occurred at a rate of 1.6 vs 1.4 per 1000 catheter days in the heparin and ethanol groups respectively (IRR 0.85; 95% CI 0.20-3.5 p =0.82 (for ethanol vs heparin. Conclusions Catheter survival and catheter-related blood stream infection were not significantly different but there was a trend towards a reduced rate of infection in the ethanol group. This study establishes proof of concept and will inform an adequately powered multicentre trial to definitively examine the efficacy and safety of ethanol locks as an alternative to current therapies used in the prevention of catheter-associated blood stream infections in patients dialysing with tunnelled catheters.

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

Background Catheter-associated urinary tract infections (CAUTI) are costly, common and often preventable by reducing unnecessary urinary catheter (UC) use. Methods To summarise interventions to reduce UC use and CAUTIs, we updated a prior systematic review (through October 2012), and a meta-analysis regarding interventions prompting UC removal by reminders or stop orders. A narrative review summarises other CAUTI prevention strategies including aseptic insertion, catheter maintenance, antimicrobial UCs, and bladder bundle implementation. Results 30 studies were identified and summarised with interventions to prompt removal of UCs, with potential for inclusion in the meta-analyses. By meta-analysis (11 studies), the rate of CAUTI (episodes per 1000 catheter-days) was reduced by 53% (rate ratio 0.47; 95% CI 0.30 to 0.64, p<0.001) using a reminder or stop order, with five studies also including interventions to decrease initial UC placement. The pooled (nine studies) standardised mean difference (SMD) in catheterisation duration (days) was −1.06 overall (p=0.065) including a statistically significant decrease in stop-order studies (SMD −0.37; p<0.001) but not in reminder studies (SMD, −1.54; p=0.071). No significant harm from catheter removal strategies is supported. Limited research is available regarding the impact of UC insertion and maintenance technique. A recent randomised controlled trial indicates antimicrobial catheters provide no significant benefit in preventing symptomatic CAUTIs. Conclusions UC reminders and stop orders appear to reduce CAUTI rates and should be used to improve patient safety. Several evidence-based guidelines have evaluated CAUTI preventive strategies as well as emerging evidence regarding intervention bundles. Implementation strategies are important because reducing UC use involves changing well-established habits. PMID:24077850

Our aim was to evaluate the equivalence between analytic parameters from blood samples obtained from a saline solution lock device used for the infusion of drugs and those from venipuncture. In our emergency department, patients bearing a saline solution lock device have blood extracted by venipuncture to avoid possible contamination of the sample. Adults from the emergency department with a saline solution lock device who required laboratory tests were selected as candidates for this cross-sectional observational study. Infusions were halted and flushed with 0.9% saline solution; 2 minutes later, 2 mL of blood was drawn and discarded, and the corresponding laboratory tubes were filled. Immediately after, another sample was withdrawn from the opposite extremity by venipuncture. Both samples were analyzed for hematology, biochemistry, venous blood gases, and coagulation parameters. Concordance was evaluated by use of the intraclass correlation coefficient with its 95% confidence intervals; Bland-Altman plots were used to illustrate the percentage of samples with differences exceeding 2 SDs. The mean differences were also checked to detect those exceeding the laboratory's systematic error. An intraclass correlation coefficient of over 0.9 was achieved for all parameters except for pH, partial pressure of carbon dioxide, and partial pressure of oxygen. Differences of over 2 SDs were found in fewer than 10% of all parameters. None of them exceeded 3 SDs, except for pH and venous blood gases. All parameters showed differences below the laboratory's accepted systematic error except for pH and venous blood gases. Blood samples extracted from a peripheral catheter with or without drug infusions are valid for the analysis of hematology, biochemistry, and coagulation parameters but not for venous blood gases. Nurses should know the benefits of using an existing peripheral catheter for drawing blood samples for laboratory analysis even when infusing commonly used drugs

éter con su retirada inmediata cuando posible. La mayoría de los estudios analizados mostraron una reducción significante de infección sanguínea relacionadas o asociadas con catéteres intravenosos centrales.This is an integrative review of literature aimed to identify evidence-based interventions which make up care bundles to reduce central venous catheter-related or associated bloodstream infections. To collect data in Brazilian and international databases were used the key word bundle and the descriptors catheter-related infection, infection control and central venous catheterization, resulting in fifteen articles, after inclusion criteria application. This work showed five interventions as those commonly employed in the bundles methods: hand hygiene, chlorhexidine gluconate for skin antisepsis, use of maximal sterile barrier precaution during the catheter insertion, avoid the femoral access and daily review of catheter necessity with prompt removal as no longer essential. The majority of the studies showed a significant reduction in bloodstream infection related to or associated with central venous catheters.

Peripherally inserted central venous catheters (PICCs) are now commonly used for central access in the intensive care unit (ICU) setting; however, there is a paucity of data evaluating the complication rates associated with these lines. We performed a retrospective review of all PICCs placed in the inpatient setting at our institution during a 1-year period from January 2013 to December 2013. These were divided into two groups: those placed at the bedside in the ICU and those placed by interventional radiology in non-ICU patients. Data regarding infectious and thrombotic complications were collected and evaluated. During the study period, 1209 PICC line placements met inclusion criteria and were evaluated; 1038 were placed by interventional radiology in non-ICU patients, and 171 were placed at the bedside in ICU patients. The combined thrombotic and central line associated blood stream infection rate was 6.17 per cent in the non-ICU group and 10.53 per cent in the ICU group (P = 0.035). The thrombotic complication rate was 5.88 per cent in the non-ICU group and 7.60 per cent in the ICU group (P = 0.38), whereas the central line associated blood stream infection rate was 0.29 per cent in the non-ICU group and 2.92 per cent in the ICU group (P = 0.002). This study seems to suggest that PICC lines placed at the bedside in the ICU setting are associated with higher complication rates, in particular infectious complications, than those placed by interventional radiology in non-ICU patients. The routine placement of PICC lines in the ICU settings needs to be reevaluated given these findings.

To evaluate the cost-effectiveness of the antiseptic-impregnated catheter compared with conventional catheters in preventing catheter- related blood stream infections (CR-BSI). Cost-effectiveness analysis; clinical trial, experimental, randomized, controlled, prospective, open label. Patients and methods. A 172 patient cohort, under 1-year-old or less than 10 kg, postoperative cardiovascular children with central venous catheters (CVC) admitted to Cardiac Intensive Care Unit (UCI 35) at Hospital Nacional de Pediatría "Prof. Dr. Juan P. Garrahan", since September 2005 to December 2007. Demographic and CVC data were retrieved to compare: age, gender, weight, diagnosis, surgery, CVC days, costs and complications. Intervention. CVC Arrow, double-lumen, > 48 h of duration; intervention group: antiseptic-impregnated CVC vs. control group: CVC without antiseptics (conventional). The incidence of CR-IE (CR-Infected Events: colonization, local infection and/or CRBSI; combined end point) was 27% for antiseptic- impregnated CVC vs. 31% for conventional catheters (p= 0.6) with similar accumulated incidence of CR- BSI: 2.8 vs. 3.3 per 1000 dayscatheter. We found no differences between groups, except in weight: median 4.0 kg (r 2-17) vs. 4.7 kg (r 2-9) p= 0.0002 and age, median 2 months (r 1- 48) vs. 5 months (r 1- 24) p= 0.0019 in antiseptic-impregnated CVC group. These differences, though statistically significant were clinically non relevant. Median cost per patient during intensive care stay in the conventional CVC group was $3.417 (359-9.453) and in the antiseptic-impregnated-CVC group was $4.962 (239-24.532), p= 0.10. The use of antiseptic-impregnated CVC compared with conventional CVC did not decrease CR-BSI in this population. The cost per patients was higher in the antiseptic impregnated CVC group. These results do not support the routine use of this type of CVC in our population.

The effectiveness of the calf-squeeze technique during aspiration thrombectomy using guiding catheter in the treatment of an acute lower extremity deep vein thrombosis (DVT) was evaluated by the use of imaging and the clinical follow-up of patients. A prospective analysis of ten patients (seven women, three men; median age, 56.9 years) with common iliac vein (CIV) obstruction and ipsilateral DVT was performed for this study. All patients presented with leg edema or pain and were treated with catheter-directed thrombolysis via an ipsilateral popliteal vein approach after insertion of a temporary inferior vena cava (IVC) filter. Subsequently, the patients were treated with by aspiration thrombectomy using a guiding catheter to remove the residual thrombus. The calf-squeeze technique during aspiration thrombectomy can be used to induce the proximal migration of thrombi in the popliteal, tibial, and muscular veins were used to increase venous flow. The calf-squeeze technique was employed at mean of 1.3 times (range, 1-3 times). All patients showed proximal migration of a popliteal and muscular vein thrombus during the execution of the calf-squeeze technique. Successful recanalization was achieved in all patients (100%) without any complications. On duplex ultrasonography, which was performed immediately after the aspiration thrombectomy, four patients had a residual thrombus in the soleal muscular veins. However, none of the patients had a thrombus in the popliteal and tibial veins; and, during follow-up, no DVT recurred in any patient. The use of the calf-squeeze technique during aspiration thrombectomy after catheter-directed thrombolysis can induce the proximal migration of thrombi in the popliotibial and muscular veins and is an effective method that can remove a thrombus in calf veins.

There is no consensus definition to distinguish infectious from non-infectious phlebitis associated to peripheral venous catheter. To evaluate the impact of an intervention program on the rate of infectious (those associated to bacteremia or local purulent discharge) and non-infectious phlebitis (the rest) and identify differential features. Interventional study developed in three stages: basal measurement, intervention, and evaluation. Ten infectious and 186 non-infectious phlebitis were registered. Infectious phlebitis diminished after intervention (0.2 to 0.04 events per 1,000 bed-days; p = 0.02) but not the rest (2.3 per 1,000 bed-days before and after). Five of 10 patients with infectious phlebitis had bacteremia, one with infectious endocarditis and valve replacement, and other with septic shock and a fatal outcome. None of the patients in the non-infectious group presented complications. Infectious phlebitis appeared later (mean 4.1 versus 2.4 days; p = 0.007) and were associated to fever (40% vs 5.9%, p = 0.004). Non-infectious phlebitis was associated to irritating compounds (OR 6.1; IC95 1.3-29, p phlebitis. Distinction appears to be relevant because those of infectious origin are associated with fever, complications or death, respond to an intervention program, and emerge lately.

Umbilical Venous Catheter (UVC) are commonly used in neonatal period; they can be not correctly positioned and could be associated with complications. The purpose of this article is to suggest a flow-chart to evaluate the placement of UVC, testing it in young radiologists-in-training. We developed a simple flow-chart to asses, steps by step, UVC placement considering its course and tip location (ideally placed in the atriocaval junction). We tested the flow-chart impact asking to 20 residents to evaluate the placement of 10 UVC before and after they familiarized with the flow-chart and the anatomical findings of a newborn. The agreement among the 20 students was evaluated too. The number of correct characterizations was different due to the administration of the flow-chart. One hundred and six correct UVC assessments at the beginning switched to 196 after the administration of the flow-chart (p = 0.0001). The observed agreement among the twenty radiology residents was statistically significant, both before (kappa = 0.41, p < 0.001) and after (kappa = 0.37, p < 0.001) the flow-chart administration. The developed flow-chart demonstrated to be useful in increasing residents performance in UVC placement assessment.

Purpose: To assess the incidence of infections and its influence on the survival of radiologically inserted Hickman catheters (HCs) in patients with hematologic disorders and to determine factors associated with premature HC removal. Methods: Survival and complications of 175 HCs in 115 patients were studied retrospectively. To describe the data the Kaplan-Meier method and the log-rank test were used, using the date of HC removal due to HC-related infection as endpoint. A stratified Cox regression model was used to determine explanatory factors. Results: Seventy (40%) HCs were removed prematurely because of proven or probable HC-related infections. The incidence of infection leading to HC removal was 4.78 per 1000 catheter-days for proven HC infections. Univariate analysis revealed that acute myeloid leukemia, acute lymphocytic leukemia, or treatment for these diseases, gender, each subsequent catheter in the same patient and insertion site increased the risk of premature removal of the catheter due to infection. Conclusion: Infection is a major problem in patients with HCs. Unfortunately, the factors associated with increased infection rates that were found in this study cannot be influenced. Further studies are necessary to determine the role of environmental conditions in a radiology suite in relation to the risk of developing a catheter-related infection

Totally implantable venous access ports (TIVAPs) are used for prolonged central venous access, allowing the infusion of chemotherapy and other fluids and improving the quality of life of children with cancer. TIVAPs were developed to reduce the infection rates associated with central venous catheters; however, infectious events remain common and have not been fully investigated in pediatric oncology patients. A retrospective cohort was formed to investigate risk factors for central line-associated bloodstream infection (CLABSI) in pediatric cancer patients. Sociodemographic, clinical, and TIVAP insertion-related variables were evaluated, with the endpoint being the first CLABSI. A Kaplan-Meier analysis was performed to determine CLABSI-free catheter survival. Overall, 188 children were evaluated over 77,541 catheter days, with 94 being diagnosed with CLABSI (50%). Although coagulase-negative staphylococci were the pathogens most commonly isolated, Gram-negative microorganisms (46.8%) were also prevalent. In the multivariate analysis, factors that increased the risk for CLABSI were TIVAP insertion prior to chemotherapy (risk ratio [RR] = 1.56; P Risk factors for CLABSI in pediatric cancer patients with a TIVAP may be related to the severity of the child's condition at catheter insertion. Insertion of the catheter before chemotherapy and unfavorable conditions such as malnutrition and bone marrow aplasia can increase the risk of CLABSI. Protocols must be revised and surveillance increased over the first 10 weeks of treatment. © 2016 Wiley Periodicals, Inc.

venous patency was 3.5 (2, 5) in Group A and 0 (0, 1) in Group B with significant difference (Z=-5.7702, P<0.01). The rate of venous patency after the treatment was 55.0% (42.3%, 72.4%) in Group A and 100% (88.5%, 100%) in Group B,with significant difference (Z=4.9148, P<0.01). The total dose of urokinase used in the treatment was 5.950 (5.525, 7.225) × 10 6 U in Group A and 4.100 (3.600, 5.050) × 10 6 U in Group B with significant difference (Z=-6.0133, P<0.01). The retention time of perfusion catheter was 10 (9, 12) d in Group A and 6 (5, 7) d in Group B with significant difference (Z=-8.0358, P<0.01). No symptomatic pulmonary embolism occurred in both groups during the treatment and follow-up period. The rate of bleeding complication was 38.0% (19/50) in Group A and 22.3% (10/44) in Group B, without significant difference (χ 2 =2.5590, P=0.1097). The removal rate of optional filter was 88.37% (38/43) in Group A and 100% (39/39) in Group B, with significant difference (χ 2 =4.829, P=0.028).The rate of venous patency at the last follow-up point was 50.0% (44.4%,59.2%) in Group A, and 95.4% (83.6%, 100%) in Group B, with significant difference (Z=-3.2721, P=0.0011). Conclusions: Balloon-assisted CDT was a promising treatment for acute lower-extremity DVT. It improved the effect of thrombolysis and reduced the dosage of urokinase, and did not increase the risk of pulmonary embolism. (authors)

S. aureus is a Gram positive bacterium which is responsible for a wide range of infections. This pathogen has also the ability to adhere to biotic or abiotic surface such as central venous catheter (CVC) and to produce a biofilm. The aim of this study was to evaluate the effect of hexadecyltrimethyl ammonium bromide (HTAB) and Hexadecylbetainate chloride (HBC) on Staphylococcus aureus adherence to the catheter tubing and on bacteria growth. Broth microdilution method was used to determine the Minimal Inhibitory Concentration (MIC). The detection of slime production was done by Congo Red Agar method, and the adherence of bacteria to the catheter tubing was evaluated by the enumeration of bacteria on plate counts. The results of this study showed that the MICs of HTAB were ranged from 0.125 to 0.5 µg/mL, and those of HBC fluctuated between 2 to 8 µg/mL. HTAB and HBC inhibited bacteria adhesion on the surface of the catheter tubing. This study showed that HTAB and HBC can prevent the adherence of S. aureus strains to the surface of catheter tubing, suggesting that they could be used to prevent the risk of catheter related bloodstream infections.

2011-12-01

A 41-year-old woman, who had no thrombotic risk factors and past history except congenital scoliosis, underwent central venous catheterization (CVC) before correction of the scoliosis. When internal jugular vein (IJV) catheterization using the anatomical landmark technique failed, CVC under ultrasound guidance was tried. As a consequence, thrombosis and hypoplasia of the right IJV were incidentally detected by ultrasonography. Central venous catheters were then successfully placed in other veins under ultrasound guidance. Also, after examinations to rule out the possibility of pulmonary embolism and to clarify the causes of the IJV thrombosis, the patient was found to have protein S deficiency. CVC under ultrasound guidance should be recommended to prevent the failure of cannulation and complications such as thromboembolism in patients who could possibly have anomalies of vessels as a result of anatomical deformities caused by severe scoliosis, even if patients do not have thrombotic risk factors such as a history of central catheter insertion or intravenous drug abuse, cancer, advanced age, cerebral infarction, and left ventricular dysfunction. Also, if venous thrombosis is found in patients without predisposing risk factors, one should ascertain the cause of the hypercoagulable state, for example protein S deficiency, and perform appropriate treatment and prevention of venous thromboembolism.

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

Abnormal systemic venous connection possibly associated with a persistent right umbilical vein; a case report

Full Text Available Abstract Background Abnormal venous connections involving a persistent right umbilical vein are rare. In a minority of cases the liver is entirely bypassed and the condition is associated with multiple congenital malformations. Case presentation The described case illustrates a systemic venous drainage that was severely abnormal in a newborn girl with a truncus arteriosus type II congenital heart defect. Injection of contrast medium through the umbilical vein catheter revealed a very peculiar venous connection that passed anterio-laterally through the right hemithorax before crossing in an oblique fashion towards the superior vena cava. Conclusions This venous drainage may be the result of a persistent right umbilical vein connecting with the superior vena cava.

To examine the impact of tamsulosin on the rate of acute urinary retention following early catheter removal after robot-assisted laparoscopic radical prostatectomy. A total of 236 patients who underwent robot-assisted laparoscopic radical prostatectomy for prostate cancer carried out by a single surgeon were enrolled in this randomized study. Patients were randomly divided into two groups: treatment with tamsulosin (0.4 mg) from 1 day before to 14 days after surgery (tamsulosin group), or no tamsulosin treatment (control group). The urethral catheter was removed on the fifth postoperative day. The primary end-point was the acute urinary retention rate. Changes in each domain of the International Continence Society male short-form questionnaire and uroflowmetry parameters were secondary end-points. The primary end-point was assessed in 218 patients (92.4%; n = 109 in each group). It was not assessed in 18 patients because of cystographic leak from the vesicourethral anastomosis. The acute urinary retention rate was lower in the tamsulosin group (7.3%) than in the control group (17.4%, P = 0.018). Multivariate logistic regression analysis identified tamsulosin treatment and the operative experience of the surgeon as independent risk factors for acute urinary retention. Tamsulosin-treated patients had a 0.30-fold lower risk of developing acute urinary retention compared with control patients (95% confidence interval 0.12-0.76; P = 0.011). None of the International Continence Society male questionnaire domain scores showed significant changes between the groups. Perioperative treatment with tamsulosin in patients undergoing robot-assisted laparoscopic radical prostatectomy reduces the rate of acute urinary retention after early catheter removal, without aggravating urinary incontinence. © 2013 The Japanese Urological Association.

Scientific data from current literature demonstrate an incidence of bacteraemia due to tunnelled central venous catheter (tCVC) use accounting for 1.6 / 1000 days per tCVC, with a range of 1.5 to 1.8. In Sicily no data on the incidence of tCVC- related bacteraemia are available. In our hospital, tCVC infection occurs 2.4 times in 1000 days during CVC use. A retrospective analysis carried out from 2006 to 2012 was performed on 650 patients with tunnelled catheters. Of the subjects who received tCVC in our hospital, 90% were destined to undergo haemodialysis in a private health care environment outside our hospital. In order to improve the aforementioned infection outcome, we planned and implemented a specific work project. The work project (WP) was subdivided into two steps: 1) The first step was further subdivided into two sub-phases. The first was principally concerned with the implementation of educational courses, conducted directly on the ward and aimed at the implementation of meticulous nursing regimes for the care of tCVC by our health care nurse. The courses were entitled Management of Vascular Access: from doing - to teaching to do!. These educational courses were organized by the Nephrology Department, which takes care of the management and handling of the major complications of tCVCs for the maintenance of haemodialysis. After this first step, the nurses who had participated became the promoters of the second part of the course, which concerned the development of know-how within an outpatient clinic, which deals exclusively with the nursing management of tCVCs. 2) The title of the second phase was Therapeutic Education: self-Care and understanding and managing your venous access at home. The aim of this step was the integration of correct in-hospital care with that available in outsourced private institutions, via the involvement of the patient in the management of their own central venous access. During our training project, a more detailed analysis of

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

The purpose of this study was to evaluate whether low-profile totally implanted central venous port systems can reduce the late complication of skin perforation. Forty patients (age, 57 ± 13 years; 22 females, 18 males) were randomized for the implantation of a low-profile port system, and another 40 patients (age, 61 ± 14 years; 24 females, 16 males) received a regular port system as control group. Indications for port catheter implantation were malignant disease requiring chemotherapy. All port implantations were performed in the angiography suite using sonographically guided central venous puncture and fluoroscopic guidance of the catheter placement. Procedure time, number of complications (procedure-related immediate, early, and late complications), and number of explantations were assessed. Follow-up was performed for 6 months. All port implantations were successfully completed in both study groups. There were two incidents of skin perforation observed in the control group. One skin perforation occurred 13 weeks and the other 16 weeks after port implantation (incidence, 5%) in patients with regular-profile port systems. Two infections were observed, one port infection in each study group. Both infections were characterized as catheter-related infections (infection rate: 0.15 catheter-related infections per 1000 catheter days). In conclusion, low-profile port systems can be placed as safely as traditional chest ports and reduce the risk of developing skin perforations, which occurs when the port system is too tight within the port pocket.

To prospectively evaluate the perioperative safety, early complications and satisfaction of patients who underwent the implantation of central catheters peripherally inserted via basilic vein. Thirty-five consecutive patients with active oncologic disease requiring chemotherapy were prospectively followed up after undergoing peripheral implantation of indwelling venous catheters, between November 2013 and June 2014. The procedures were performed in the operating room by the same team of three vascular surgeons. The primary endpoints assessed were early postoperative complications, occurring within 30 days after implantation. The evaluation of patient satisfaction was based on a specific questionnaire used in previous studies. In all cases, ultrasound-guided puncture of the basilic vein was feasible and the procedure successfully completed. Early complications included one case of basilic vein thrombophlebitis and one case of pocket infection that did not require device removal. Out of 35 patients interviewed, 33 (94.3%) would recommend the device to other patients. Implanting brachial ports is a feasible option, with low intraoperative risk and similar rates of early postoperative complications when compared to the existing data of the conventional technique. The patients studied were satisfied with the device and would recommend the procedure to others.

Totally implantable port systems are generally recommended for prolonged central venous access in diverse settings, but their risk of complications remains unclear for patients with advanced cancer. The aim of this study was to assess the risk of port system failure in patients with advanced cancer. We conducted a retrospective cohort study in a comprehensive cancer centre. A detailed chart review was conducted among 566 patients with 573 ports inserted during January-June, 2009 (average 345.3 catheter-days). Cox regression analysis was applied to evaluate factors during insertion and early maintenance that could lead to premature removal of the port systems due to infection or occlusion. Port system-related infection was significantly associated with receiving palliative care immediately after implantation (hazard ratio, HR = 7.3, 95% confidence interval, 95% CI = 1.2-46.0), after adjusting for probable confounders. Primary cancer site also impacted the occurrence of device-related infection. Receiving oncologic/palliative care (HR = 3.0, P = 0.064), advanced cancer stage (HR = 6.5, P = 0.077) and body surface area above 1.71 m(2) (HR = 3.4, P = 0.029) increased the risk of port system occlusion. Our study indicates that totally implantable port systems yield a higher risk of complications in terminally ill patients. Further investigation should be carefully conducted to compare outcomes of various central venous access devices in patients with advanced cancer and to develop preventive strategies against catheter failure.

1986-11-01

A technique for duodenal alimentation (needle catheter duodenostomy) of birds was developed, using the domestic pigeon (Columba livia) as the experimental model. A needle catheter was inserted into the descending duodenum of 5 pigeons and was secured to the body wall and dorsum of each bird. A liquid diet was administered daily (in equal amounts of 0, 4, 8, 12, and 16 hours) for 14 days without adverse effects. On day 15, the catheters were removed, and the birds immediately resumed normal consumption of a pigeon ration and water diet. Although 4 of the 5 birds had minor weight loss, dietary alterations probably could be used on an individual basis to alleviate this problem. After oral alimentation was resumed, the 5 birds exceeded their initial body weight within 7 days. Four weeks after catheter removal, positive-contrast radiographic evaluations indicated that the duodenum of each pigeon appeared normal. Needle catheter duodenostomy was a viable method of alimentation in the domestic pigeon. This technique should be applicable for other avian species requiring bypass of the upper gastrointestinal tract proximal to the region of catheter insertion in the duodenum.

Safety, dose, and timing of reteplase in treating occluded central venous catheters in children with cancer.

Recombinant tissue plasminogen activator, alteplase, began to be commonly used to restore the patency of occluded central venous catheters (CVCs) as urokinase production was halted in the late 1990s. However, alteplase often requires an extended dwell time to restore patency to occluded CVCs. In adults, reteplase, a newer thrombolytic agent, has been reported to restore patency to CVCs in 30 minutes. The authors prospectively evaluated the safety and efficacy of reteplase in restoring patency to occluded CVCs in children with cancer. This was a dose escalation trial. The dose of reteplase was initiated at 0.1 units and increased by increments of 0.1 units to a maximum dose of 0.4 units. Each dose was tested on at least three participants. Time to patency after reteplase administration was recorded by nurses caring for the patients. Attempts to access the line occurred every 15 minutes for 1 hour. CVCs that remained occluded after 1 hour were treated with alteplase. Reteplase was administered to 15 clotted CVCs. Twelve of the 15 were cleared with an average dwell time of 38 minutes. The time to patency did not appear to correlate with the dose. No adverse events were reported. Reteplase can restore patency to occluded CVCs in a pediatric population. Reteplase appears to have comparable efficacy with alteplase, but reteplase may require shorter dwell times. A prospective, randomized, clinical trial is warranted to determine whether reteplase is as effective as alteplase in restoring patency to occluded CVCs.

Quantity of residual thrombus after successful catheter-directed thrombolysis for iliofemoral deep venous thrombosis correlates with recurrence.

Science.gov (United States)

Aziz, F; Comerota, A J

2012-08-01

Iliofemoral deep venous thrombosis (IFDVT) is an independent risk factor for recurrent DVT. It has been observed that recurrent DVT correlates with residual thrombus. This study evaluates whether risk of recurrence is related to the amount of residual thrombus following catheter-directed thrombolysis (CDT) for IFDVT. Patients who underwent CDT for IFDVT had their degree of lysis quantified by a reader blind to the patients' long-term clinical outcome. Patients were classified into two groups, ≥50% and thrombus. Recurrence was defined as a symptomatic presentation with image verification of new or additional thrombus. A total of 75 patients underwent CDT for IFDVT. Median follow-up was 35.9 months. Sixty-eight patients (91%) had no evidence of recurrence and seven (9%) developed recurrence. Of the patients who had ≥50% (mean 80%) residual thrombus, 50% (4/8) experienced recurrence, but in those with thrombus, only 5% (3/67) had recurrent DVT (P = 0.0014). The burden of residual thrombus at completion of CDT correlates with the risk of DVT recurrence. Patients having CDT for IFDVT had a lower risk of recurrence than expected. Successful clearing of acute clot in IFDVT patients significantly reduces the recurrence risk compared to patients with a large residual thrombus burden.

A retrievable Guenther Tulip caval filter(William Cook, Europe) was successfully placed and retrieved in the superior vena cava for upper extremity deep venous thrombosis in a 56-year-old woman. Bilateral subclavian and internal jugular venous thromboses thought secondary to placement of multiple central venous catheters were present. There have been reports of the use of permanent Greenfield filters and a single case report of a temporary filter in the superior vena cava. As far as we are aware this is the first reported placement and successful retrieval of a filter in these circumstances

In this study we investigated the influences of decreased levels of activities of daily living (ADL), especially in bedridden patients,on lower urinary tract dysfunction and urinary management during hospital care. All 1,106 non-urological inpatients (896 non-bedridden patients and 210 bedridden patients) with an indwelling urethral catheter treated at Noto General Hospital between April 2006 and October 2009 were retrospectively evaluated. Maximum bladder capacity and post-void residual urine volume (PVR) were evaluated with uroflowmetry or voiding cystourethrography at the time the catheter was removed. Clean intermittent catheterization (CIC) and drug administration were performed for patients who had a PVR of 100 ml or more. Bedridden patients required urinary interventions at a higher rate than did non-bedridden patients (bedridden : 29.0%,non-bedridden : 17.6%). Although indwelling urethral catheters were reinserted in 13 patients in the bedridden group and 16 patients in the non-bedridden group,many patients in both groups could be free from the catheter. Our results indicate that patients with low ADL are vulnerable to impaired bladder emptying,and early diagnosis of impaired bladder emptying and active urinary management are required to solve their urinary problems.

Essentials It is unclear if thrombophilia increases the risk of catheter-associated thrombosis in children. We conducted a meta-analysis on thrombophilia and pediatric catheter-associated thrombosis. Presence of ≥1 trait confers additional risk of venous thrombosis in children with catheters. Limitations of included studies preclude us from recommending routine thrombophilia testing. Background The association between thrombophilia and deep vein thrombosis (DVT) associated with central venous catheter (CVC) use, the most important pediatric risk factor for thrombosis, is unclear in children. Pediatric studies with small sample sizes have reported conflicting results. We sought to evaluate whether, among children with CVCs, thrombophilia increases the risk of CVC-associated DVT (CADVT). Materials and methods We systematically searched MEDLINE, EMBASE, the Web of Science, the Cochrane Central Register for Controlled Trials, PubMed and reference lists for controlled studies published from the inception of the database until September 2015. Included were studies of children aged levels and the FV Leiden mutation had an increased prevalence of CADVT. The association with thrombophilia seemed to be stronger for symptomatic CADVT (pOR 6.71; 95% CI 1.93-23.37) than for asymptomatic CADVT (pOR 2.14; 95% CI 1.10-4.18). Conclusions On the basis of the low prevalence of specific traits, the relatively weak association with CADVT, and the limitations of the included studies, we cannot recommend routine testing of thrombophilias in children with CADVT. © 2016 International Society on Thrombosis and Haemostasis.

Although epidural anesthesia is considered safe, several complications may occur during puncture and insertion of a catheter. Incidences of paresthesia vary between 0.2 and 56%. A prospective, open, cohort-controlled pilot study was conducted in 188 patients, ASA I-III, age 19-87 years, scheduled for elective surgery and epidural anesthesia. We evaluated a 20 G polyamide (standard) catheter and a 20 G combined polyurethane-polyamide (new) catheter. Spontaneous reactions upon catheter-insertion, paresthesia on questioning, inadvertent dural or intravascular puncture, and reasons for early catheter removal were recorded. The incidence of paresthesia reported spontaneously was 21.3% with the standard catheter and 16.7% with the new catheter. Systematically asking for paresthesia almost doubled the paraesthesia rate. Intravascular cannulation occurred in 5%. No accidental dural punctures occurred. An overall incidence of 13.3% of technical problems led to early catheter removal. The new catheter was at least equivalent to the standard regarding epidural success rate and safety : rate of paresthesia, intravascular and dural cannulation.

Intrathecal catheter placement has long-term therapeutic benefits in the management of chronic, intractable pain. Despite the diverse clinical applicability and rising prevalence of implantable drug delivery systems in pain medicine, the spectrum of complications associated with intrathecal catheterization remains largely understudied and underreported in the literature. To report a case of thoracic nerve root entrapment resulting from intrathecal catheter migration. Case report. Inpatient hospital service. A 60-year-old man status post implanted intrathecal (IT) catheter for intractable low back pain secondary to failed back surgery syndrome returned to the operating room for removal of IT pump trial catheter after experiencing relapse of preoperative pain and pump occlusion. Initial attempt at ambulatory removal of the catheter was aborted after the patient reported acute onset of lower extremity radiculopathic pain during the extraction. Noncontrast computed tomography (CT) subsequently revealed that the catheter had ascended and coiled around the T10 nerve root. The patient was taken back to the operating room for removal of the catheter under fluoroscopic guidance, with possible laminectomy for direct visualization. Removal was ultimately achieved with slow continuous tension, with complete resolution of the patient's new radicular symptoms. This report describes a single case report. This case demonstrates that any existing loops in the intrathecal catheter during initial implantation should be immediately re-addressed, as they can precipitate nerve root entrapment and irritation. Reduction of the loop or extrication of the catheter should be attempted under continuous fluoroscopic guidance to prevent further neurosurgical morbidity.

2010-01-01

The purpose of this study was to examine the incidence of new or recurrent venous thromboembolism (VTE) after retrieval of inferior vena cava (IVC) filters and risk factors associated with such recurrence. Between March 2001 and September 2008, at our institution, implanted retrievable vena cava filters were retrieved in 76 patients. The incidence of new or recurrent VTE after retrieval was reviewed and numerous variables were analyzed to assess risk factors for redevelopment of VTE after filter retrieval. In 5 (6.6%) of the 76 patients, redevelopment or worsening of VTE was seen after retrieval of the filter. Three patients (4.0%) had recurrent deep venous thrombosis (DVT) in the lower extremities and 2 (2.6%) had development of pulmonary embolism, resulting in death. Although there was no significant difference in the incidence of new or recurrent VTE related to any risk factor investigated, a tendency for development of VTE after filter retrieval was higher in patients in whom DVT in the lower extremities had been so severe during filter implantation that interventional radiological therapies in addition to traditional anticoagulation therapies were required (40% in patients with recurrent VTE vs. 23% in those without VTE; p = 0.5866 according to Fisher's exact probability test) and in patients in whom DVT remained at the time of filter retrieval (60% in patients with recurrent VTE vs. 37% in those without VTE; p = 0.3637). In conclusion, new or recurrent VTE was rare after retrieval of IVC filters but was most likely to occur in patients who had severe DVT during filter implantation and/or in patients with a DVT that remained at the time of filter retrieval. We must point out that the fatality rate from PE after filter removal was high (2.6%).

Role of ultrasound for central catheter tip localization in neonates: a review of the current evidence.

Science.gov (United States)

Sharma, Deepak; Farahbakhsh, Nazanin; Tabatabaii, Seyyed Ahmad

2018-02-15

Central catheters are known as "life lines" in intensive care units and are used frequently in neonatal intensive care unit (NICU) for multiple indications. The central catheters used in NICU includes umbilical venous catheter (UVC), umbilical arterial catheter (UAC) and peripherally inserted central catheter (PICC) lines. The tip of these central lines needs to be in a correct position as malpositioned central line tips lead to many neonatal complications. Radiograph either abdomen or chest is the most widely used modality for locating the tip of the central catheter. There are many disadvantages of radiographic confirmation of tip position and recently ultrasound (USG)/echocardiography has been used for localization of catheter tip. USG provides real-time assessment of the tip position with other added advantages like no radiation exposure, need for minimal training for performing USG, minimal handling of the neonate, identification of migration of central lines and making repositioning of central lines under USG guidance. The present evidence supports the use of USG/Echo for localization of central catheter tip and USG has shown to have good sensitivity, specificity, positive predictive value and negative predictive value when compared with a radiograph. In this review, we discuss about the role of USG/Echo in the identification of tip of central catheters in neonatal care.

Catheter Associated Urinary Tract Infection Prevention bundle

Directory of Open Access Journals (Sweden)

O. Zarkotou

2017-01-01

Full Text Available Catheter-associated urinary tract infections (CAUTI are among the most common healthcare-associated infections, and potentially lead to significant morbidity and mortality. Multifaceted infection control strategies implemented as bundles can prevent nosocomial infections associated with invasive devices such as CAUTIs. The components of the CAUTI bundle proposed herein, include appropriate indications for catheterization and recommendations for the procedures of catheter insertion and catheter maintenance and care. Avoiding unnecessary urinary catheter use is the most effective measure for their prevention. To minimize the risk of CAUTI, urinary catheters should be placed only when a clinical valid indication is documented and they should be removed as soon as possible; alternatives to catheterization should also be considered. Aseptic insertion technique, maintenance of closed drainage system and strict adherence to hand hygiene are essential for preventing CAUTI. The successful implementation of the bundle requires education and training for all healthcare professionals and evaluation of surveillance data.

Dose requirements for UVC disinfection of catheter biofilms

DEFF Research Database (Denmark)

Bak, Jimmy; Ladefoged, Søren D.; Tvede, Michael

2009-01-01

Bacterial biofilms on permanent catheters are the major sources of infection. Exposure to ultraviolet-C (UVC) light has been proposed as a method for disinfecting the inner surface of catheters. Specification of a UVC-based device for in vivo disinfection is based on the knowledge of the required...... doses to kill catheter biofilm. Given these doses and the power of available UVC light sources, calculation of the necessary treatment times is then possible. To determine the required doses, contaminated urinary catheters were used as test samples and UVC treated in vitro. Patient catheters (n = 67......) were collected and cut into segments of equal size and treated with various UVC doses. After treatment, the biofilm was removed by scraping and quantified by counting colony forming units. Percentage killing rates were determined by calculating ratios between UVC-treated samples and controls (no UVC...

Gram-positive microorganisms have been the predominant pathogens in central venous catheter-related bloodstream infections (CRBSIs). Recent guidelines recommend empirical therapy according to this and restrict coverage for Gram-negatives to specific circumstances. This study aimed to analyse the epidemiological changes in CRBSIs over the 1991-2008 period and to analyse predictors of Gram-negative CRBSIs. A prospectively collected cohort of patients with confirmed CRBSIs was analysed. Strains isolated and antimicrobial susceptibility, as well as clinical and demographic variables were recorded. Differences observed during the study period were analysed by means of a χ² trend test and factors associated with Gram-negative CRBSIs by means of multivariable analysis. Between 1991 and 2008, 1129 episodes of monomicrobial CRBSIs were recorded. There was an increase in the incidence of CRBSIs, from 0.10 (1991-92) to 0.31 (2007-08) episodes/1000 patient-days. A significant increase in the number of Gram-negative strains among the total isolates was also found, from 3 (4.7%) in 1991-92 to 70 (40.23%) in 2007-08, with a parallel decrease in the percentage of Gram-positives. Solid organ transplantation, prior use of penicillins and hospital stay longer than 11 days were independently associated with a significantly higher risk of Gram-negative CRBSIs, while cirrhosis, diabetes and use of quinolones were associated with a higher risk of Gram-positives. Gram-negative strains are an increasing cause of CRBSIs, reaching a prevalence of 40% in the 2007-08 period in our hospital. If this trend is confirmed in other centres, a broad-spectrum empirical therapy should be considered in managing these infections.

To evaluate the effectiveness of percutaneous catheter drainage in treatment of the lung abscess. We treated the lung abscesses in 14 patients (12 mean, 2 women), who did not respond to medical therapy, by percutaneous catheter drainage under fluoroscopic or ultrasound guidance. One abscess due to infacted bulla was managed by combination treatment with alcohol sclerosing therapy. Patients were followed by serial chest radiographs every three days and the amount of drained or aspirated pus evaluated. The treatment effect and recurrence were followed by chest PA and lateral chest at one week after removal of drainage catheter. Thirteen patients (93%) recovered clinically and radiologically within 3 days. In 10 patients, drainage catheter could be removed within 2 weeks, and three patients, the catheter was kept longer. Most complications were mild; vague to moderate chest pain (n = 14), mild hemoptysis (n = 2), and pneumothorax (n = 1). One man who suffered from far advanced pulmonary tuberculosis died of asphyxia caused by massive hemoptysis 16 days after percutaneous drainage. Percutaneous catheter drainage is a safe and effective method for treating lung abscess.

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

Objective To identify patient, hospital and central venous catheter (CVC) factors that may influence the use of low dose heparin infusion (LDHI) for CVC patency in critically ill-children. Design Secondary analysis of an international multicenter observational study. Setting 59 Pediatric Intensive Care Units (PICUs) over four study dates in 2012, involving 7 countries. Patients Children less than 18 years of age with a CVC, admitted to a participating unit and enrolled in the completed PROTRACT study were included. All overflow patients were excluded. Interventions None. Measurements and Main Results Of the 2,484 patients in the PROTRACT study, 1,312 patients had a CVC. 507 of those patients used LDHI. The frequency of LDHI was compared across various patient, hospital and CVC factors using chi-squared, Mann-Whitney and Fisher's exact tests. In the multivariate analysis, age was not a significant factor for LDHI use. Patients with pulmonary hypertension had decreased LDHI use while those with active surgical or trauma diagnoses had increased LDHI use. All central CVC insertion sites were more likely to use LDHI when compared to peripherally inserted CVCs. The Asia-Pacific region showed increased LDHI use, along with community hospitals and smaller ICUs (LDHI in critically ill children. Further study is needed to evaluate the efficacy and persistence of LDHI use. PMID:27362853
