Abstract Introduction: Patients with solid tumors have an increased risk for venous thromboembolisms (VTE) associated with substantial morbidity and mortality, but so far there exists little data on hematologic malignancies. We have recently found a VTE rate of 7,7% in patients with malignant lymphoma. However, information on patients with acute leukemia (AL) is very limited so far. Patients and methods: Medical records of all patients with AL treated in our institution between january 1992 and april 2005 were reviewed and data was collected and analyzed in a microsoft excel data base. P-values to show correlation of VTE with leukemia type, patient age and gender were calculated using Fisher’s exact test. All reported p-values are two-sided. Results: Of a total of 455 patients 310 (68%) had AML, 108 (24%) had ALL and 37 (8%) had blast crisis. 248 patients (55%) were male and 207 (45%) were female, median age was 60 years. 55 patients with AL (12,1%) had at least one VTE, occuring during therapy in 82% of events. 27 patients (5,9%) had central venous catheter associated VTE, whereas 28 patients (6,2%) had deep vein thrombosis and/or pulmonary embolism. Neither leukemia lineage - myeloid versus lymphocytic - (p=1,0) nor patient gender (p=.193) had an impact on the VTE risk. However, central venous catheter associated VTE more likely occured in younger patients (< 60 years) than in patients ≥ 60 years (p=.003). There was no statistically significant difference in the incidence of non-central venous catheter associated VTE between both age groups (p=.563). Discussion: Patients with acute leukemia have a substantial risk for VTE, half of which occur with the use of central venous catheters. A recently published study analysed the incidence of VTE in close temporal relationship to onset of disease and found a VTE rate of 2,09% with equal risk in ALL and AML. Our study included VTE occuring prior to diagnosis of AL as well as during chemotherapy and follow up, revealing a VTE rate that is 6-fold higher and showing a considerable association with central venous catheters. Conclusions: The risk of VTE is surprisingly high in patients with acute leukemia, thus improvement of prophylactic measures, especially in regard to central venous catheter use is warranted.

Background: Central venous catheter guidewire retention is classed as a ‘never event’ in the United Kingdom, with the potential for significant patient harm. If the retained guidewire remains within the central venous catheter lumen, bedside techniques may facilitate guidewire retrieval. However, these techniques may be ineffective if the guidewire has already passed below skin level. We investigated a novel ‘suck out’ technique for bedside guidewire retrieval and compared this against traditional retrieval methods. Methods: Simulation 1: in a benchtop model, seven different central venous catheters had their corresponding guidewire placed in the last 2 cm of the catheter tip which was immersed horizontally in fluid. A 50-mL syringe was attached to the distal lumen central venous catheter hub and suction applied for 5 s, and the distance of guidewire retraction was recorded. Simulation 2: a central venous catheter guidewire was intentionally retained within the catheter at either 5 cm above or below skin level in a pigskin model. Simple catheter withdrawal, catheter clamping withdrawal and the ‘suck out’ method were compared for efficacy using Fisher’s exact test. Results: Simulation 1: retained guidewires were retracted by 13 cm on average. Simulation 2: when guidewires were retained 5 cm above skin level, all retrieval methods were 100% effective; however, when retained 5 cm below skin level, simple catheter withdrawal was ineffective, clamping and withdrawal was only 10% effective and the ‘suck out’ technique was 90% effective (p < 0.001). Conclusion: The ‘suck out’ technique can effectively retract guidewires retained within central venous catheter lumens and demonstrates superiority over traditional methods of retained guidewire extraction in simulated models.

Vasopressors are ubiquitous in intensive care units. While central venous catheters are the preferred route of infusion, recent evidence suggests peripheral administration may be safe for short, single-agent courses. Here, we identify risk factors and develop a predictive model for patient central venous catheter requirement using the Medical Information Mart for Intensive Care, a single-centre dataset of patients admitted to an intensive care unit between 2008 and 2019. Using prior literature, a composite endpoint of prolonged single-agent courses (>24 hours) or multi-agent courses of any duration was used to identify likely central venous catheter requirement. From a cohort of 69,619 intensive care unit stays, there were 17,053 vasopressor courses involving one or more vasopressors that met study inclusion criteria. In total, 3807 (22.3%) vasopressor courses involved a single vasopressor for less than six hours, 7952 (46.6%) courses for less than 24 hours and 5757 (33.8%) involved multiple vasopressors of any duration. Of these, 3047 (80.0%) less than six-hour and 6423 (80.8%) less than 24-hour single vasopressor courses used a central venous catheter. Logistic regression models identified associations between the composite endpoint and intubation (odds ratio (OR) 2.36, 95% confidence intervals (CI) 2.16 to 2.58), cardiac diagnosis (OR 0.72, CI 0.65 to 0.80), renal impairment (OR 1.61, CI 1.50 to 1.74), older age (OR 1.002, Cl 1.000 to 1.005) and vital signs in the hour before initiation (heart rate, OR 1.006, CI 1.003 to 1.009; oxygen saturation, OR 0.996, CI 0.993 to 0.999). A logistic regression model predicting the composite endpoint had an area under the receiver operating characteristic curve (standard deviation) of 0.747 (0.013) and an accuracy of 0.691 (0.012). This retrospective study reveals a high prevalence of short vasopressor courses in intensive care unit settings, a majority of which were administered using central venous catheters. We identify several important risk factors that may help guide clinicians deciding between peripheral and central venous catheter administration, and present a predictive model that may inform future prospective trials.

Context: Central venous access device (CVAD) bundles for insertion and maintenance demonstrate a reduction in the frequency of complications and bloodstream infection when implemented with compliance monitoring, with the reported success of CVAD bundles. Aim: This study aimed to examine the effect of central venous catheter care bundle implementation on outcomes of critically ill patients. Methods: Quasi-experimental research (pre/post-test design) used to achieve the aim of this study. The study conducted at general and surgical intensive care units affiliated to Menoufia University and teaching hospital. Two study samples recruited in this study. All nurses working at the ICUs, as mentioned above, were recruited in this study. They were 6o critical care nurses. A convenient sample of all available critically ill patients at the time of the study was subjected to treatment via a central venous catheter. Four study tools used to collect the data of this study. These are a structured interview questionnaire, CVC nurses’ knowledge assessment questionnaire, nurses’ compliance assessment checklists, and patient complications assessment records. Results: The study result showed a highly statistically significant difference between pre and post-test knowledge scores of studied nurses regarding assisting line insertion, removal, maintenance, care, and infection control practices. Besides, a highly statistically significant difference between pre and post-test scores of nurses’ compliance to central venous catheter care practices of assisting in CVC insertion, blood sample withdrawal, medication and fluid administration, CVP measurements, CVC removal, and the management of central venous line complications. The study also revealed a highly statistically significant difference between the study and control group patients regarding the central venous catheter complications. However, signs of infection were the most frequent complications in both groups. Conclusion. The study concluded that a statistically significant difference between pre and post nurses’ knowledge and compliance with the CVC care bundle. The patients’ outcomes were also improved significantly after the implementation of the CVC care bundle compared to the controls. The study recommended the adoption of the current care bundle that should be disseminated and updated following the international organizations’ recommendation for implementing evidence-based practices for successful central line-associated bloodstream infection (CLABSI) prevention.

Background: Central venous catheter (CVC) complication rates reflecting the application of modern insertion techniques to a clinically heterogeneous patient populations are needed to better understand procedural risk attributable to the 3 common anatomic insertion sites: internal jugular, subclavian, and femoral veins. We sought to define site-specific mechanical and duration-associated CVC complication rates across all hospital inpatients. Methods: A retrospective chart review was conducted over 9 months at Georgetown University Hospital and Washington Hospital Center. Peripherally inserted central catheters and tunneled or fluoroscopically placed CVC’s were excluded. Mechanical complications (retained guidewire, arterial injury, and pneumothorax) and duration-associated complications (deep vein thrombosis or pulmonary embolism, and central line-associated bloodstream infections) were identified. Results: In all, 1179 CVC insertions in 801 adult patients were analyzed. Approximately 32% of patients had multiple lines placed. Of 1179 CVCs, 73 total complications were recorded, giving a total rate of one or more complications occurring per CVC of 5.9%. There was no statistically significant difference between site-specific complications. A total of 19 mechanical complications were documented, with a 1.5% complication rate of one or more mechanical complications occurring. A total of 54 delayed complications were documented, with a 4.4% complication rate of 1 or more delayed complications occurring. There were no statistically significant differences between anatomic sites for either total mechanical or total delayed complications. Conclusions: These results suggest that site-specific CVC complication rates may be less common than previously reported. These data further inform on the safety of modern CVC insertion techniques across all patient populations and clinical settings.

Abstract Purpose: To validate the formula-based central venous catheter (CVC) length measurement “tailored” to individual's height and access site for predicting optimum SVC tip position. Method: A prospective study of 3 percutaneous insertion sites (PICC, SCC and JC). Formula-based “LUM'S CVC MEASUREMENT GUIDE” was used to determine the catheter length. Results: Overall, 97% (373) of the total 382 insertions were successfully placed with CVC tip in the distal SVC (SVC between carina and atrio-cava junction) location. Conclusion: The “tailored fit” formula to individual patient height is a reliable tool to predict CVC length. Appropriate catheter length can greatly reduce the guesswork and possibility of complications related to tip malposition.

Abstract The needleless closed system (NCS) has been disseminated in several clinical fields to prevent central venous catheter–related bloodstream infection (CVC-RBSI), in place of the conventional Luer cap system (LCS). The purpose of this study is to examine whether NCS is really superior to conventional LCS for prevention of CVC-RBSI. Between May 2002 and December 2008, 1767 patients received CVC in our department. The time interval from insertion to development of CVC-RBSI was compared retrospectively between selected patients who were treated using the conventional LCS (group 1, n = 89, before June 2006) and the NCS (group 2, n = 406, June 2006 and after). Kaplan-Meier analysis revealed no significant difference in the time interval from insertion to development of CVC-RBSI between the two groups. NCS does not reduce CVC-RBSI in adult colorectal cancer patients who undergo CVC insertion.

Background: Catheter-related bloodstream infections caused by Staphylococcus aureus represent one of the most fearful infections in chronic haemodialysis patients with tunnelled central venous catheters. Current guidelines suggest prompt catheter removal in patients with positive blood cultures for S. aureus. This manoeuvre requires inserting a new catheter into the same vein or another one and is not without its risks. Methods: A protocol based on early, prompt diagnosis and treatment has been utilized in our renal unit since 2012 in an attempt to salvage infected tunnelled central venous catheters. We prospectively observed 247 tunnelled central venous catheters in 173 haemodialysis patients involving 167,511 catheter days. Results: We identified 113 catheter-related bloodstream infections (0.67 episodes per 1000 days/tunnelled central venous catheter). Forty were caused by S. aureus, including 19 by methicillin-resistant S. aureus (79% saved) and 21 by methicillin-sensitive S. aureus (90% saved), of which 34 (85%) were treated successfully. Eight recurrences occurred and six (75%) were successfully treated. A greater than 12 h time to blood culture positivity for S. aureus was a good prognostic index for successful therapy and tunnelled central venous catheter rescue. Conclusion: Our data lead us to believe that it is possible to successfully treat catheter-related bloodstream infection caused by S. aureus and to avoid removing the tunnelled central venous catheter in many more cases than what has been reported in the literature. On the third day, it is mandatory to decide whether to replace the tunnelled central venous catheter or to carry on with antibiotic therapy. Apyrexia and amelioration of laboratory parameters suggest continuing systemic and antibiotic lock therapy for no less than 4 weeks, otherwise, tunnelled central venous catheter removal is recommended.

The neonatal population is at a particularly high risk for catheter-associated bloodstream infections (CABSI). Chlorhexidine for skin antisepsis is well documented to effectively decrease the incidence of bloodstream infections associated with central venous catheters in other populations. The project described in this article demonstrates that chlorhexidine for central venous catheter insertion and line maintenance in the neonatal population safely and effectively reduces CABSI.
