Analysis of Vascular Access in Haemodialysis Patients - Single Center Experience.

Vascular access is the key in successful management of chronic haemodialysis (HD) patients. Though native arteriovenous fistula (AVF) is considered the access of choice, many patients in our country initiate haemodialysis through central venous catheter (CVC). There is paucity of data on vascular access in haemodialysis patients from southern India. Aim of the present study was to review our experience of vascular access in Haemodialysis patients (both central venous catheters and arteriovenous fistula) and to assess its success rate and common complications. This prospective study was conducted between January 2014 and December 2014 in our institute. A total of 50 patients with Chronic Kidney Disease (CKD) underwent vascular access intervention during the above period. A temporary venous catheter (96%) in the right internal jugular vein was the most common mode of initiation of haemodialysis with 34.48% incidence of catheter related sepsis. Fifty percent of catheters were removed electively with mean duration of catheter survival of 77.23 ± 14.8 days. Wrist AVF (60%) was the most common site of AVF creation followed by arm (30%), mid-forearm (7.5%) and leg (2.5%). Complications include distal oedema (17.5%) and venous hypertension (2.5%). Primary failure occurred in 25% of patients and was more common in diabetic, elderly (>60 years) and in distal fistulas. Elderly patients (>60 years) starting dialysis with a CVC were more likely to be CVC dependent at 90 days. Late presentation and delayed diagnosis of chronic kidney disease (CKD) necessitates dialysis initiation through temporary catheter. Dialysis catheter with its attendant complications further adds to the morbidity, mortality, health care burden and costs. Early nephrology referral and permanent access creation in the pre dialysis stage could avert the unnecessary complications and costs of catheter.

A Multicentred Clinical Improvement Project Among Preterm Population Evaluation of Current Practices

Sepsis, a potentially life-threatening infection, is a common complication related to the use of central venous catheters (CVCs) in the preterm infant population. Best practice guidelines include successful strategies to prevent infections. Central venous catheter use is a fairly recent intervention in Finnish neonatal intensive care units (NICUs). As part of a quality improvement project to evaluate catheter-related care practices, 4 NICUs collaborated in a multicenter, multiprofessional study aimed at decreasing the incidence of catheter-related sepsis among a population of preterm infants. This article describes the initial phase that evaluated current protocols and practices. The findings were that current protocols need revision to include more detailed and accurately focused instructions on infection prevention associated with CVC. Many challenges in performing certain procedures with catheters were found. Precis CVC protocols and practices in 4 Finnish NICUs were reviewed for infection control measures.

Vancomycin flush solution for prevention of catheter-related infections in oncology patients with PICC: a systematic review of the effectiveness

Objective To assess the efficacy of vancomycin flush solution for prevention of catheter-related infections in oncology patients. Methods Randomized controlled trials(RCTs) were searched and identified from Cochrane library, PubMed, EMBASE, CBM, CNKI and related journals were also scanned. In accordance with inclusion and exclusion criteria, we evaluated the quality of the included studies by Jadad scale and analyzed the data of catheter- related sepsis, catheter colonization, exit- site infection by RevMan 5.0. Results We included 5 randomized controlled trials (400 patients). Meta analysis showed that there were statistical differences between vancomycin- heparin mixture and heparin solution on the incidence of catheter-related sepsis, catheter colonization, but no difference was found on the incidence of exit-site infection. Conclusions The current evidences show that contrast with heparin flush solution, van comycin - heparin flush solution can significantly reduce the incidence, of catheter - related sepsis and catheter colonization. But vancomycin-heparin flush solution was more effective, and the results should be further confirmed in prevention of Gram-positive bacterial and fungal catheter-related infections or in non- neutropenic patients. Before draw the conclusions, further high-quality, large scale, double-blind randomized controlled trials are still needed. Key words: Vancomycin; Prophylaxis; CVCs; Infection; Systematic review

Central venous catheter placement by an interventional radiology unit: An Australian experience

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 (<24 h), early (24 h-30 days) and late (>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.

Cost savings of an adult hospital nutrition support team

Objectives A hospital-based nutrition support team (NST) may need to demonstrate cost savings and quality benefits. The primary aim of this study was to determine whether an NST could show tangible cost savings (equipment, investigations, and medication costs) from managing patients considered for parenteral nutrition (PN). Secondary aims related to the quality issues of placement of PN catheters, catheter-related sepsis (CRS), duration of parenteral nutrition, and mortality. Methods An NST was formed in 1999 and worked in all adult areas of a university hospital (Leicester Royal Infirmary). Comparative data about all patients given PN were collected for 2 consecutive years (a retrospective pre-NST year and a prospective NST year). Results In the pre-NST year there were 82 PN episodes (54 patients), 665 PN days, and a CRS rate of 71% (seven infections/100 PN days). In the NST year, there were 133 referrals for PN but only 78 PN episodes (75 patients, 59% of referrals), 752 PN days, and a decreased overall CRS rate of 29% (three infections/100 PN days, P < 0.05) but a rate of 7% (0.6 infection/100 PN days) in the final 3 mo of the NST year. Tangible cost savings for the NST year were derived from 55 avoided PN episodes (£42741) and 35 avoided CRS episodes (£7974). Thirty-nine percent of PN catheters were inserted by the NST with no insertion-related complications. Competency-based training of ward nursing staff decreased the CRS rate. Mean duration of PN increased from 8 to 10 d ( P not significant). In-hospital mortality for patients who had PN was 23 of 54 (43%) in the pre-NST year compared with 18 of 75 (24%) in the NST year ( P < 0.05). Conclusions Although the number of PN days increased with an NST, tangible cost savings of £50715 were demonstrated within the NST year by avoided PN episodes and a decreased incidence of CRS. These savings justify the salaries of a nutrition nurse specialist and a senior dietitian.

A multicenter, randomized, double-blind, placebo-controlled trial of the prokinetic agent erythromycin in the postoperative recovery of infants with gastroschisis

Background/purpose The recovery of gut function after repair of gastroschisis is frequently prolonged, and these infants are prone to complications associated with parenteral nutrition. This trial was designed to investigate the effect of the prokinetic agent, erythromycin, on the attainment of full enteral feeding in infants after primary repair of uncomplicated gastroschisis. Methods A multicenter, randomized, double-blind, placebo-controlled trial was used to investigate the effect of enteral erythromycin (3 mg/kg/dose 4 times daily) compared with placebo on the attainment of full enteral feeding tolerance after primary repair of uncomplicated gastroschisis. Eleven neonatal surgical units in the United Kingdom participated in the study. The primary end-point was the time taken to achieve continuous enteral feeding at 150 mL/kg/24 hours sustained for 48 hours. Results Of 70 eligible infants, 62 were recruited and randomly divided. There were 30 patients in group I (placebo) and 32 in group II (erythromycin). The groups were comparable in terms of mean gestational age, mean birth weight, extent of evisceration, and degree of intestinal peel. There was no statistically significant difference between the 2 groups in the time taken to achieve full enteral feeding (27.2 v 28.7 days; P = .75). Similarly, no significant differences were found in the incidence of catheter-related sepsis, duration of parenteral nutrition, or time to discharge between the 2 groups. Conclusions Enterally administered erythromycin at a dose of 3 mg/kg 4 times daily conferred no advantage in the time taken to achieve full enteral feeding after primary repair of uncomplicated gastroschisis.

Líneas de actuación para la inserción, montaje y manipulación de un sistema de válvulas para los catéteres venosos centrales

In order to reduce the incidence of catheter related sepsis and the factors associated to it, our unit established some performance lines for the insertion, assembly and handling of a valvular system for the central venous catheters.

Randomized controlled trial of heparin for prevention of blockage of peripherally inserted central catheters in neonates

To determine whether the addition of heparin to total parenteral nutrition (TPN) fluid would prevent blockage of peripherally inserted central catheters (PICCs) in neonates. This was a randomized, double-blind, controlled study of 66 eligible neonates with PICCs inserted for the administration of TPN. Infants were randomized to receive TPN containing either 1 IU ml(-1) of heparin (n = 35) or no heparin (n = 31). There was no significant difference in the incidence of blocked catheters between the two groups of infants (heparin: 14.3%; no-heparin: 22.6%, p = 0.4). Although a higher percentage (62.9%) of infants in the heparin group received a complete course of TPN successfully via PICC than those in the no-heparin group (48.4%), the difference was not statistically significant (p = 0.3). There were no significant differences in the incidence of catheter-related sepsis, hypertriglyceridaemia, hyperbilirubinaemia, coagulopathy or intraventricular haemorrhage between the two groups. Addition of heparin to TPN fluid was not associated with a significant reduction in the incidence of blocked PICCs. However, the sample size of this study was too small to exclude even rather marked differences between the groups.

Preventing nosocomial bloodstream infection in very low birth weight infants.

Nosocomial sepsis is a frequent complication of caring for very low birth weight infants and incidence varies substantially among centres. Many cases are preventable. An organized approach to understanding the epidemiology of nosocomial sepsis within a unit, and implementing evidence-based practices can successfully reduce the incidence. Diagnostic accuracy is important to limit excess empiric antibiotic therapy. Instituting a hand hygiene program of education, monitoring, and consideration of waterless hand disinfectants to avoid hand transmission of organisms is essential. An emphasis on early achievement of enteral nutrition, preferably with human milk is important to reduce unnecessary exposure to central catheters and parenteral nutrition. Use of maximum sterile barrier precautions by personnel trained and skilled in central catheter insertion, followed by meticulous care in preventing catheter hub contamination will reduce the incidence of catheter related sepsis. Ultimately, the culture of the NICU needs to shift from a focus on early detection of infection to one of prevention.

Changing profile of parenteral nutrition in pediatric surgery: A 30-year experience at one institute

Due to technical refinements and steady advances in the development of highly sophisticated nutrient solutions consisting of optimal combinations of macronutrients and micronutrients, parenteral nutrition (PN) is now playing an important role in patient management. However, some PN-associated complications, such as catheter-related sepsis (CRS) and cholestasis, continue at high incidence, particularly in neonates. The objective of this study was to investigate the changing profiles of PN over the past 30 years in our department. The medical records of 893 children (225 neonates, 245 infants, 261 preschool-age children, and 162 school-age children) who were placed on PN for >7 days in our department were reviewed, and the following data were extracted: birth weight, underlying disease, indications for PN, PN delivery route, type of catheter used, duration of PN, substrate and energy intake, type of amino acid solution used, and incidence of complications including CRS and liver dysfunction. The results were analyzed by dividing the patients into 3 groups according to their basic stages in management of PN and consisted of group 1 (1970 to 1979), group 2 (1980 to 1989), and group 3 (1990 to 1999). The parameters were compared in each group. The total number of patients in each group showed no significant difference; however, the percentage of low birth-weight neonates increased in group 3. In group 1, 85% of PN was administered through the peripheral vein; in group 2, 51.2%; and in group 3, 9.7%. The total calorie and nutrient intake decreased in groups 2 and 3 compared with group 1, particularly regarding fat intake. In groups 1 and 2, commercially available amino acid solution based on the Food and Agriculture Organization/World Health Organization formula was usually used as the nitrogen source, but in group 3, it was changed to an amino acid solution for children. CRS decreased significantly, particularly in neonates, and occurred at a rate of 45.4% in group 1, 10.7% in group 2, and 1.5% in group 3. The incidence of liver dysfunction also showed a decrease: 35.7% in group 1, 22.3% in group 2, and 18.0% in group 3. A multivariate analysis showed a strong relationship between PN-related liver dysfunction and the duration of PN, the presence of infection, and the type of amino acid solution used. PN via central venous catheters has been regarded as safe and effective treatment in pediatric surgical patients. Over the past 30 years, the incidence of CRS has decreased. However, PN-related liver dysfunction remains a problem, particularly in patients receiving long-term PN.

Catheter-related sepsis in the neonate: thinking critically about a persistent problem.

Catheter-related sepsis (CRS) is a clinical problem gaining increasing attention in the literature. Before strategies for reducing the incidence of CRS can be identified, a consistent definition of the problem must be developed. Critical thinking is an intellectual process used to reflect upon a topic of interest. The critical thinking process provides a framework for comprehensive analysis of patient care problems. The article describes the critical thinking process and proposes a model of critical thinking for practicing nurses. This model is applied to the development of comprehensive definitions for CRS that may be used by neonatal nurses for clinical and research purposes.

Complications of Swan-Ganz catheterization for hemodynamic monitoring in patients with subarachnoid hemorrhage.

Invasive hemodynamic monitoring has become standard in the management of aneurysmal subarachnoid hemorrhage. This study is a retrospective analysis of 630 Swan-Ganz catheters placed in 184 patients with aneurysmal subarachnoid hemorrhage. Evaluation of complications demonstrated a 13% incidence of catheter-related sepsis (81 of 630 catheters), a 2% incidence of congestive heart failure (13 of 630 catheters), a 1.3% incidence of subclavian vein thrombosis (8 of 630 catheters), a 1% incidence of pneumothorax (6 of 630 catheters), and a 0% incidence of pulmonary artery rupture. In the management of patients with aneurysmal subarachnoid hemorrhage, invasive hemodynamic monitoring continues to be an important tool with acceptable complications.

A Prospective Randomized Comparison of an Attached Silver-Impregnated Cuff to Prevent Central Venous Catheter-Associated Infection

The VitaCuff catheter, a specialized central venous catheter (CVC) with an attached silver-impregnated cuff, is designed to permit percutaneous placement and prolonged venous access. A prospective randomized study was undertaken comparing the VitaCuff with standard triple lumen catheters to determine if the VitaCuff reduces infection during extended use. All consenting patients underwent percutaneous placement of subclavian lines. By study design, control and VitaCuff catheters could remain in site for up to 7 and 14 days, respectively. Cultures were obtained from the preinsertion skin site, and upon removal, from the skin, hubs, infusates, CVC tip, and cuff. Statistical methods included χ2, the Student t test, and the log-rank test on Kaplan-Meier estimates. Of 133 patients completing this study, 64 patients (48.1%) underwent VitaCuff placement and 69 patients (51.8%) served as controls. In 124 patients (93.2%), the indication for catheter placement was for perioperative care. Overall, 67 patients (50.4%) required central venous access >7 days. necessitating ⩾1 additional line in 29 patients (21.8%). The incidence of pneumothorax per patient from the initial central line insertion was 4/104 (3.85%), significantly lower than the 4/29 (13.8%) incidence during secondary catheter placement ( P = 0.046). Culture results upon catheter removal demonstrated a reduction in colonization of skin sites and hubs for the VitaCuff patients, but not for catheter tips or infusates. Regardless of the type of catheter used, colonization was dependent upon duration of insertion. The incidence of catheter-related sepsis was 6.8%, and did not differ significantly between the study groups. Multiple CVC insertions increase the incidence of pneumothorax. Because VitaCuff catheters permit extended access up to 14 days without increasing the incidence of sepsis, we recommend their use in patients who require prolonged CVC access.

Teicoplanin to Prevent Early Hickman Catheter-related Sepsis in Patients Receiving Intensive Chemotherapy

Background: We aimed to determine if prophylactic teicoplanin reduced catheter-related infections in patients needing intensive chemotherapy. Material and Patients: Thirty patients with hematological malignancies requiring Hickman catheters for intensive chemotherapy received two single bolus intravenous injections of teicoplanin immediately before insertion of double lumen Hickman catheter and 24 hours later. Results: We did not observe exit site infections, tunnel infections or catheter-related gram-positive septicaemia. No adverse reaction was reported in any of the patients in the prophylactic group. Conclusion: Prophylactic teicoplanin therefore may be used routinely for patients requiring insertion of Hickman catheters for intensive chemotherapy to reduce the early incidence of catheter-related sepsis, especially during the associated period of neutropenia following chemotherapy or during bone marrow transplantation.

Collodion as a Safe, Cost-Effective Dressing for Central Venous Catheters

Catheter-related sepsis continues to be a major problem with the use of central venous catheters. Controversy exists with respect to dressing material and frequency of dressing changes. Collodion is a solution of pyroxylin in a solution of 75% ether and 25% alcohol. Camphor and castor oil are added to create a flexible noncontracting dressing when applied to the skin. We retrospectively reviewed the charts of 34 patients requiring central venous catheters between 1986 and 1988. All catheters were placed via the subclavian approach. Collodion was used as a dressing on all patients. Dressings were not routinely changed. The catheters remained in position an average of 16.5 days. No insertion site became infected; one episode of catheter-related sepsis occurred, and two catheters were inadvertently dislodged. The overall incidence of catheter-related sepsis was 2.9%.

Double-blind placebo controlled study of vancomycin prophylaxis for central venous catheter insertion in cancer patients

To assess whether vancomycin administration at the time of central venous catheter insertion would prevent catheter-related sepsis (CRS) in immunocompromised patients, 98 cancer patients were entered into a randomized placebo-controlled trial. Patients were stratified according to whether they were having therapy for acute leukaemia or undergoing bonemarrow transplantation (group A) or required chemotherapy for a solid tumour (group B). Eligible patients were randomized to receive either 500 mg vancomycin in 250 ml of 0.9% saline prior to catheter insertion followed by a further 500 mg infused via the established catheter, or the same regimen with 0.9% saline alone. In group A, there were 32 instances of CRS occurring in 20 of the 35 evaluable catheters (57%). Six catheters were removed because of CRS. No significant difference was found in the incidence of CRS between the two arms. Of the 37 evaluable catheters in group B, CRS occurred in 6 (16%), and none of the catheters required removal because of CRS. Again, no significant differences were found in the incidence of CRS between the patients given vancomycin or placebo. These findings indicate that the incidence of CRS is greater in patients who have more severe and prolonged immunosuppression and that vancomycin prophylaxis fails to reduce CRS in patients undergoing chemotherapy for malignant disease.
