Peripherally Inserted Central Venous Catheter-Related Complications in Adult Patients with Haematological Malignancy.

Peripherally inserted central venous catheters (PICC) are widely used in patients with haematological malignancies owing to the requirement for prolonged intravenous therapy. However, the growing use of PICCs has resulted in a multitude of complications such as infections and thrombosis, leading to prolonged hospitalisation periods and increased morbidity. This study aimed to determine the incidence of and factors associated with PICC-related complications in patients with haematological malignancies. This prospective cohort study was conducted at a single academic institution. The inclusion criteria involved all adult patients with haematological malignancies who had newly inserted PICCs. The patients were observed for a minimum duration of 60 days to evaluate the incidence of PICC-related infections and thrombosis, as well as mechanical complications. A total of 119 PICCs were implanted in 85 patients. Among them, more than half of the patients were diagnosed with lymphoma (55.0%). The median dwell time was 61 days (interquartile range: 98 days). The incidence of PICC-related complications was 58.0% (6.9 per 1,000 catheter-days). Specifically, 43 PICCs (36.1%, 4.3 per 1,000 catheter-days) experienced infective complications, 25 (21.1%, 2.5 per 1,000 catheter-days) encountered mechanical complications and 1 (0.8%, 0.1 per 1,000 catheter-days) exhibited thrombotic complications. Furthermore, an underlying diagnosis of acute leukaemia was significantly associated with a higher incidence of PICC-related infections. Our study revealed higher incidence rates of PICC-related complications in adult patients with haematological malignancies compared to the finding of other studies. Notably, patients with underlying acute leukaemia displayed a higher incidence of PICC-related infections. These findings underscore the importance of implementing appropriate interventions and conducting thorough root cause analyses to effectively mitigate this complication and improve patient outcomes.

Risk factors for peripherally inserted central venous catheter-related complications in children: A retrospective cohort study.

To explore the risk factors for peripherally inserted central venous catheter (PICC)-related complications in children. This retrospective study analyzed data collected from electronic medical records. A total of 584 patients with indwelling PICC treated between January 2019 and August 2021 were included in this study. According to the occurrence of PICC-related complications, the patients without PICC-related complications were included in the control group (n = 538) and those with PICC-related complications were included the observation group (n = 46). The risk factors for PICC-related complications were analyzed. Of the 584 patients with PICCs, 46 (7.88%) had PICC-related complications. Univariate analysis revealed significant differences in venipuncture (P < .001), oozing of blood from the puncture point (P < .001), indwelling time (P < .001), intravenous nutrient solution (P < .001), and catheter type (P = .003). Complications were used as dependent variables. The independent variables were vein puncture, blood oozing at the puncture point, indwelling time, intravenous nutrient solution, and catheter type. Multivariate logistic regression analysis revealed that the vein puncture (odds ratio [OR] 10.115, 95% confidence interval [CI] 5.034-20.323, P < .001), puncture point blood oozing (OR 9.217, 95% CI 3.860-22.004, P < .001), indwelling time (OR 6.390, 95% CI 3.527-10.972, P = .005), intravenous nutrient solution (OR 2.593, 95% CI 1.675-4.015, P < .001), and catheter type (OR 8.588, 95% CI 2.048-19.095, P = .013) were all risk factors for PICC-related complications in children. Venipuncture, oozing of blood from the puncture point, indwelling time, intravenous nutrient solution, and catheter type are risk factors for PICC-related complications in children. Significant attention should be paid to whether the puncture point is bleeding, the presence or absence of an intravenous nutrient solution, duration of catheterization, type of catheterization, and venipuncture. Additionally, preventive nursing measures should be implemented as soon as possible to reduce the risk of complications related to peripheral PICC.

Adverse events related to central venous catheters (CVC) and the influence of CVC characteristics on peripheral blood hematopoietic progenitor cell collection in children.

The use of peripheral blood progenitor cells (PBPCs) as a source for hematopoietic stem cell transplantation (HSCT) in pediatric healthy donors is still under debate. The risk of a central venous catheter (CVC) placement and catheter-related complications continue to be the main arguments to discourage its use. we present a retrospective analysis of 140 PBPC collections in pediatric patients and donors, describing adverse events (AE) related to CVCs as well as the influence of catheterrelated variables on the efficiency of the leukapheresis. 14 CVC-related AEs were recorded (10%). The most common was fever in 5 patients, 4 of which had a catheter-related bacteriemia. Thrombotic events were only observed in 3 patients with active malignancy. A healthy donor presented a moderate bleeding after catheter withdrawal that resolved with local measures, and none of the rest presented any AE. Regarding variables related to the development of AEs, the subject group (patient or donor) was the only one significantly associated (p < 0.0001). Of interest, efficiency was also related to catheter location, being worse in those located in the femoral vein than in into the jugular or the subclavian veins (p < 0.05). In a multivariate analysis, the only variable significantly associated was catheter size (beta 0.238, p < 0.01). Placing a CVC for PBPC collection in pediatric subjects is overall safe; CVC-related complications in pediatric healthy donors are very rare. Furthermore, we should try to place catheters of the largest caliber possible, since the efficiency of the collection is related to this variable.

Evaluation of non-infectious complications in children receiving parenteral nutrition.

Parenteral nutrition may lead to inevitable complications. To determine the indications, metabolic and mechanical complications of parenteral nutrition in children. One hundred fifty-eight children (91 males; 57.8%) who received 179 episodes of individualized parenteral nutrition for ≥ 5days within 2years were analyzed. Indications and duration of parenteral nutrition, effect on growth, and metabolic and central venous catheter-related non-infectious complications were evaluated. Parenteral nutrition was administered in 179 different episodes (109 males; 60.9%), and the median age during these episodes was 64.0 (14.0-129.0) months. The most common indications were hematological malignancies, gastrointestinal surgery, and hematopoietic stem cell transplantation. Most of the electrolyte imbalances occurred in the first 3days. Hypophosphatemia (44.7%), hypomagnesemia (43.0%), hypokalemia (43.0%), hyponatremia (40.8%), and hypertriglyceridemia (38.2%) were the most common metabolic complications. Liver transaminases elevated in 32/145 (22.1%) episodes and bilirubin in 30/149 (21.0%). Ursodeoxycholic acid treatment was added to 25 patients with hypertransaminasemia and/or hyperbilirubinemia. Transaminase levels improved in 16 (64%) and bilirubin levels in 15 (60%) patients receiving ursodeoxycholic acid. Catheter thrombosis was seen in 4.5% of the episodes. The targeted energy could be given more efficiently via central catheters rather than peripheral venous accesses. Patients' bodyweights increased in 39.1% of the episodes. Close monitoring of electrolyte levels, especially in the first 3days, is crucial to prevent complications of parenteral nutrition. When individualized PN preparations are used for metabolically unstable patients, it can be easier to maintain the blood glucose, lipids, and electrolyte levels within the normal range.

Development and validation of a multivariable model predicting the required catheter dwell time among mechanically ventilated critically ill patients in three randomized trials

BackgroundThe anatomic site for central venous catheter insertion influences the risk of central venous catheter-related intravascular complications. We developed and validated a predictive score of required catheter dwell time to identify critically ill patients at higher risk of intravascular complications.MethodsWe retrospectively conducted a cohort study from three multicenter randomized controlled trials enrolling consecutive patients requiring central venous catheterization. The primary outcome was the required catheter dwell time, defined as the period between the first catheter insertion and removal of the last catheter for absence of utility. Predictors were identified in the training cohort (3SITES trial; 2336 patients) through multivariable analyses based on the subdistribution hazard function accounting for death as a competing event. Internal validation was performed in the training cohort by 500 bootstraps to derive the CVC-IN score from robust risk factors. External validation of the CVC-IN score were performed in the testing cohort (CLEAN, and DRESSING2; 2371 patients).ResultsThe analysis was restricted to patients requiring mechanical ventilation to comply with model assumptions. Immunosuppression (2 points), high creatinine > 100 micromol/L (2 points), use of vasopressor (1 point), obesity (1 point) and older age (40–59, 1 point; ≥ 60, 2 points) were independently associated with the required catheter dwell time. At day 28, area under the ROC curve for the CVC-IN score was 0.69, 95% confidence interval (CI) [0.66–0.72] in the training cohort and 0.64, 95% CI [0.61–0.66] in the testing cohort. Patients with a CVC-IN score ≥ 4 in the overall cohort had a median required catheter dwell time of 24 days (versus 11 days for CVC-IN score < 4 points). The positive predictive value of a CVC-IN score ≥ 4 was 76.9% for > 7 days required catheter dwell time in the testing cohort.ConclusionThe CVC-IN score, which can be used for the first catheter, had a modest ability to discriminate required catheter dwell time. Nevertheless, preference of the subclavian site may contribute to limit the risk of intravascular complications, in particular among ventilated patients with high CVC-IN score.Trials Registration NCT01479153, NCT01629550, NCT01189682

The Evaluation of Central Venous Catheter-related Complications in Pediatric Acute Leukemia Patients: Single Center Experience.

Central venous catheters (CVCs) are important for maintenance of childhood leukemia treatment but CVCs may develop complications. The aim of this study was to retrospectively evaluate the CVC-related complication rate, complication types, and outcome in children with acute leukemia. Complications developing in 310 CVCs (ports n=250, Hickman catheters n=60) inserted in 262 patients were evaluated. A total of 225,296 catheter days were screened. Median (range) CVC in-dwelling time was 661.5 (1 to 2636) days. In total, 157 complications developed of which 91 (58%) were infectious complications, 35 (22.3%) were vascular, 19 (12.1%) were surgical, and 12 (7.6%) were mechanical. Hickman catheters had a higher complication rate and were more prone to mechanical complications ( P <0.01) but there was no difference for other complications. A lower absolute neutrophil count at insertion was observed in children with infectious complications ( P <0.01). Seventy-eight of 136 catheters (57.3%) had to be removed prematurely. The overall complication rate was 0.65 per 1000 catheter days. In multivariate analysis, relapse leukemia, Hickman catheter and low absolute neutrophil count increased complication risk by 4.00, 1.97, and 1.92 times, respectively. Five (1.9%) deaths occurred because of catheter complications. Safe use of CVCs can be improved by early detection of complications and an experienced catheter care team.

Central venous catheter-related complications in older haemodialysis patients: A multicentre observational cohort study.

Central venous catheters (CVC) remain a commonly used vascular access option in haemodialysis, despite guidelines advising to preferably use arteriovenous fistulae. Compared to younger patients, the risk-benefit ratio of CVC in older patients might be more beneficial, but previous studies mainly focussed on catheter-related bacteraemia and/or assessed tunnelled CVC (TCVC) only. This study's aim was to compare all catheter-related infections and malfunctions in older patients with younger patients using all CVC subtypes. We used data from DUCATHO, a multicentre observational cohort study in The Netherlands. All adult patients in whom a CVC was placed for haemodialysis between 2012 and 2016 were included. The primary endpoint was the occurrence of catheter-related infections, comparing patients aged ⩾70 years with patients aged <70 years (reference). As secondary endpoints, catheter malfunctions and catheter removal due to either infection or malfunction were assessed. Using Cox proportional hazards and recurrent events modelling, hazard ratios (HR) with 95% confidence intervals (CI) were calculated with adjustment of prespecified confounders. Additionally, endpoints were assessed for non-tunnelled CVC (NTCVC) and TCVC separately. A total of 1595 patients with 2731 CVC (66.5% NTCVC, 33.1% TCVC) were included. Of these patients, 1001 (62.8%) were aged <70 years and 594 (37.2%) ⩾70 years. No statistically significant difference was found for the occurrence of catheter-related infections (adjusted HR 0.80-95% CI 0.62-1.02), catheter malfunction (adjusted HR 0.94-95% CI 0.75-1.17) and catheter removal due to infection or malfunction (adjusted HR 0.94-95% CI 0.80-1.11). Results were comparable when assessing NTCVC and TCVC separately. Patients aged ⩾70 to <70 years have a comparable risk for the occurrence of catheter-related infections and catheter malfunction. These findings may help when discussing treatment options with older patients starting haemodialysis and may inform the current debate on the best vascular access for these patients.

Safety of prolonged outpatient courses of intravenous antibiotics: a prospective cohort study

ObjectivesThe perceived need for prolonged intravenous antibiotic courses has become a major driver behind the growth of outpatient parenteral antimicrobial therapy (OPAT) services. Several recent randomized controlled trials demonstrate noninferiority of an early switch to oral therapy and highlight the need to accurately quantify harms associated with OPAT. MethodsWe conducted a 10-year prospective cohort study in a tertiary hospital OPAT service. Adults admitted to the service between 1 June 2009 and 30 June 2019 who received an intravenous antimicrobial agent were included. Adverse events (AEs) attributable to intravenous antibiotics or intravenous access were recorded in a prospectively maintained database and analyzed. ResultsThere were 4160 admissions (median length of stay: 20 days) and a total of 88 432 patient-days of observation; 135 patients (3.3% of admissions) experienced at least one major AE (1.54 per 1000 patient-days; 95% CI, 1.29–1.82). The risk of a major AE peaked in the second week of OPAT admission, with acute kidney injury (43 of 136; 32%) and severe cytopenia (42 of 136; 31%) being the most common. At least one minor AE occurred in 38.3% of admissions (1592 of 4160; 26.4 per 1000 patient-days; 95% CI, 25.4–27.5), with central venous catheter-related complications accounting for 71% of AEs (1658 of 2338). DiscussionThe incidence of major AEs during long courses of intravenous antibiotics is low, peaking in week 2 and tailing off thereafter. These results should inform decisions concerning the choice of intravenous versus oral antimicrobials.

DELAYED COMPLICATIONS OF CENTRAL VENOUS CATHETER IN PATIENTS UNDERWENT BONE MARROW TRANSPLANTATION IN SULAIMANI CITY/IRAQ

Background: Central venous catheter is essential in the management of patients undergoing bone marrow transplants, however, insertion of it has often the potential of inducing major complications. Aim: The aim of the study was to assess central venous catheter-related complications in patients underwent bone marrow transplants. Methodology: A retrospective study was carried out at Shahid Shaswary Garmian for bone marrow transplantation in Sulaimani City on 112 adult patients who underwent bone marrow transplants from June 2016 to May 2021. The patient's medical records were used to collect data regarding; patients' and CVCs characteristics, intravenous infusions, CVC-related complications; the number and type of complication. Results: The age of 52.7% was between 40-60 years, most of them were male, primary school, and from urban. The medical diagnosis for (43.8%) was multiple myeloma, majority underwent autologous transplant, Hickman line was used for 48.2%, internal jugular vein was a most used vein, the length of stay with a catheter for almost 70% was between 2 to 3 weeks, and the majority had 2 dressing per week, most of the participants received 2 bags of Fresenius, 51.8% received blood, and 92% received platelet. The catheter-related complications occurred in 65.2% of participants, the number and type of complications were varied; 42% had one, 19.6% two, and 3.6% three complications, the proportion of fibrin was 42.9% followed by infection 32.1, occlusion 10.7%, and hematoma 7.1%. The incidence of complications was higher in leukemic patients, who had allogeneic transplants and used Hickman line 88.9%. In addition, using internal jugular vein for insertion 90%, long stay with the catheter (≥ 4 weeks) 89.3% and fewer number of dressing (1 dressing/week) 100% were more problematic. Conclusions: The incidence of central venous catheter-related complications was high, almost two-thirds had at least one complication. The most common complications were fibrin and infection. The incidence of complications affects by patients' medical diagnosis, type of transplant and catheter, vein used for insertion of the catheter, the duration of stay with a catheter, and the number of dressings for catheters sit.

Central Venous Catheter-Related Infectious Complications in Pediatric Surgical Patients: A Single-Center Experience.

The purpose of this study was to estimate the rate of central venous catheter (CVC) colonization and catheter-related bloodstream infections (CRBSIs) in pediatric surgical patients at our institute and to determine the various risk factors for their occurrence. The electronic medical records of 260 children undergoing surgery with simultaneous CVC insertion were retrospectively reviewed. Data on demographics, primary organ system involved, site of CVC, CVC dwell time, CVC colonization, CRBSI, and organisms isolated on culture were collated, categorized, and analyzed. The rate of CVC colonization and CRBSI was 32.8 per 1,000 catheter days (19.6%) and 17.4 per 1,000 catheter days (10.4%), respectively. Patients with CVC colonization and CRBSI had a significantly higher proportion of patients younger than 1 year of age ( p = 0.014). The CVC dwell time was significantly higher in both CVC colonization (7 [5-8] days) and CRBSI (6 [5-9] days) patients ( p = 0.005). The frequency of femoral catheterization was significantly higher in patients with CRBSI and CVC colonization ( p < 0.001). Coagulase negative staphylococcus was the commonest isolate in CVC infections. Age (adjusted odds ratio [OR] = 0.87; p = 0.009), CVC dwell time (adjusted OR = 1.28; p = 0.003), and femoral CVC (adjusted OR = 9.61; p < 0.001) were independent risk factors for CRBSI. Conclusion: This study reveals important observations regarding the infectious complications of CVC in pediatric surgical patients. The rates of CVC colonization and CRBSI in this study were found to be higher as compared with previously reported rates in Western literature. However, these findings are significant in view of paucity of existing literature in pediatric surgical patients. In our study, higher risk of CRBSI was associated with younger age, increasing CVC dwell time, and femoral venous catheterization. We recommend strict compliance with CVC insertion and maintenance practices and adherence to CVC care bundles to minimize these serious complications.

Comparison of mechanical complications of central venous catheter according to the insertion site in an intensive care unit of Bangladesh

Background: Central venous catheter (CVC) insertion is very common in intensive care unit (ICU). CVC is usually inserted in subclavian, internal jugular and femoral veins. However, CVC insertion may lead to significant mechanical complications. Our aim was to detect the occurrence of CVC related mechanical complications according to different insertion site.&#x0D; Methods: This prospective observational study was carried out during the period of May 2016 to July 2019 in Department of Critical Care Medicine, BIRDEM General Hospital, Dhaka, enrolling 349 adult patients requiring new CVC insertion in ICU.&#x0D; Results: Among 349 study subjects, 167 CVC were inserted through subclavian vein, 88 through internal jugular and 94 through femoral vein. There was no significant difference among three groups (subclavian / internal jugular / femoral) in terms of age, gender distribution, presence of co-morbid illness.Total mechanical complicationsin study population was 43 (12.3 %) including pneumothorax (14, 4.0%), arterial puncture (10, 2.9%), hemorrhage (11, 3.2%), catheter tip malposition (6, 1.7%), hemothorax (1, 0.3%) and lost guidewire (1, 0.3%). Pneumothorax was more with internal jugular (9.1%) than subclavian (3.6 %) route, which was statistically significant (p=0.007). Although hemorrhage and arterial puncture events were higher with femoral site than subclavian or internal jugular, which were not significant. Catheter tip malposition occurred in 4 (2.4%) patients with subclavian insertion and 2 (2.3%) patients with internal jugular site, no such event in femoral site. Hemothorax and lost guidewire occurred in only 1 patient with subclavian and internal jugular site respectively. Site-wise total mechanical complications were higher in internal jugular (17.0%) followed bysubclavian (10.8%) site and femoral site (10.6%).&#x0D; Conclusion: In this study, though not statistically significant, CVC related mechanical complications occurred more in subclavian site than in internal jugular or femoral insertion site.&#x0D; Birdem Med J 2020; 10(2): 115-119

Influence of the Insertion Site on Central Venous Catheter-Related Complications in Patients Undergoing Allogeneic Hematopoietic Cell Transplantation.

Central venous catheters (CVCs) are extensively used in patients undergoing allogeneic hematopoietic cell transplantation (HCT). In these patients CVC are placed routinely either via the internal jugular vein (IJV) or the subclavian vein (SCV). Purpose of this study was to systematically analyze complications of CVC at different insertion sites in HCT recipients. In this retrospective analysis, all consecutive patients (n=56) who received a CVC (n=101) due to allogeneic HCT at our institution between January 2011 and June 2013 were included. Three-lumen standard, nontunneled CVCs were placed via either the IJV (n=60; 59%) or the SCV (n=41; 41%). Study endpoints were time to local inflammation at the insertion site, time to fever, time to a combined endpoint of inflammation and fever, central line-associated bloodstream infection (CLABSI), duration of catheterization, catheter lumen obstruction, deep-vein thrombosis, pneumothorax, and catheter-related death. The median duration of catheterization per CVC was almost identical for the IJV and SCV sites (18 days versus 17 days; P not significant). There were no differences in the frequency of CLABSI, deep-vein thrombosis, pneumothorax, and catheter lumen obstruction between IJV and SCV CVC insertion sites. None of the patients died due to a CVC-related cause. Local inflammation occurred less frequently (48% versus 71%; P = .025) and later (median time to local inflammation, 25 days versus 12 days; P = .01) in IJV CVCs versus SCV CVCs. There was a trend toward a median longer time to the occurrence of fever for IJV CVCs compared with SCV CVCs (20 days versus 13 days; P=.07). In the multivariate analysis, diagnosis of acute leukemia (hazard ratio [HR], 1.696; P = .036), SCV CVC (HR, 1.617; P =.039), and neutropenic CVC-days (HR, 2.477; P = .01) were identified as risk factors for the occurrence of local inflammation or fever. In contrast to earlier studies in patients without hematologic malignancies, these data demonstrate that CVCs placed in the SCV are not superior over IJV CVCs. Moreover, local inflammation occurred earlier and more frequently in patients with an SCV CVC.

Comparison of Hickman Versus Proline Central Venous Catheters in Pediatric Patients Undergoing Hematopoietic Stem Cell Transplant

Introduction Central venous catheter (CVC) access is an essential component of pediatric hematopoietic stem cell transplant (HSCT). Long-term CVC access is associated with an increased risk of infection and device dysfunction. Studies have shown that one in four CVC devices in the pediatric population require removal prior to completion of treatment due to infectious or mechanical complications. A retrospective analysis evaluated CVC-related complications in Hickman versus Proline catheters among pediatric HSCT recipients. Methods We performed a detailed retrospective chart review of CVC related complications among pediatric patients who underwent HSCT between June 2016 and October 2019. During the study period there was a change in the standard CVC access device from Hickman to Proline catheter. We compared the complications related to Hickman Catheter (Cohort 1) to Proline line (Cohort 2). All patients received antibacterial prophylaxis with cefepime. Results Thirty- two patients with a median age 7 years (range 0.75-19) underwent HSCT for malignant (N=16) or nonmalignant (N=16) disease. The majority underwent allogeneic HSCT (N=29). CVC complications requiring line removal occurred in 3 out of 15 (20%) HSCTs in Cohort 1 in comparison to 2 out of 18 (11%) in Cohort 2. Of the 3 complications in Cohort 1, 2 (66%) were related to infection and 1 (33%) due to device malfunction. Both line removals in Cohort 2 were due to device malfunction. There was one documented central line infection in Cohort 2 that did not require line removal. Conclusion Results of this small pilot study suggests that Proline catheters for long-term access in pediatric HSCT recipients may lead to a decrease incidence of complications requiring line removal in comparison Hickman catheters. Further research is indicated in order to provide recommendations for the optimal CVC for long-term access in pediatric HSCT.

Percutaneous Inserted Venous Catheter via Femoral Vein in Extremely Low-Birth-Weight Infants: A Single-Center Experience.

This study aimed to assess the applicability of the insertion of small diameter catheters through the femoral vein in extremely low-birth-weight (ELBW) infants. All femoral small diameter catheters (Silastic or femoral arterial catheter [FAC]) inserted in ELBW infants in a tertiary level neonatal intensive care unit were retrospectively reviewed. Success rate, dwelling time, and percutaneously inserted central venous catheter-related complications were recorded. Thirteen small diameter catheters were inserted in seven ELBW infants. Mean gestational age at birth was 25+3 weeks (standard deviation [SD] ± 2.12) and mean birth weight was 686 g (SD ± 204.9). Mean weight at the first time of insertion was 1,044 g (SD ± 376.3). In two occasions, a FAC was used instead of a Silastic. In most cases (11/13, 84.6%), the patient was intubated prior to the procedure. The mean dwelling time was 16.7 days (SD ± 9.8). Most of the inserted small diameter catheters were removed electively (8/12, 66.7%), except for one episode of clinical sepsis from coagulase-negative Staphylococcus and three cases of accidental line extravasation. No other complications were reported. The success rate was 92.3%. Femoral venous catheterization using small diameter catheters in ELBW infants may be promising when other routes have been exhausted. Our results support that it is a feasible technique that can be performed at the bedside with successful results when conducted by experienced personnel.

Central venous catheter-related complications in the treatment of cancer patients: A prospective study of over 124,000 catheter days.

e18264 Background: Central venous catheters (CVCs) play an essential role in the management of cancer patients, however, but it causes some adverse events like catheter-related thrombi, catheter correlation infection, exudate, catheter blockage and catheter exfoliation. This research aims to evaluate incidence and risk factors of CVC-related complications in cancer patents. Methods: A prospective study of cancer patients with CVC insertion was performed from January 1, 2015 to December 31, 2018. Chest X-ray examination was performed to determine the position of the catheter tip after insertion. All patients received catheter care twice a week in our hospital until CVC were removed. Doppler ultrasound was used in all patients during the use of the CVC device or before extubation. Patients without thrombus recorded the value of the D-Dimer at the time of catheterization, while those diagnosed with thrombi recorded the value of D-Dimer the nearest time before the discovery of thrombi. Results: From 5356 patients with 6519 cases, 1398 patients with 1626 cases were enrolled, for a total of 124,242 catheter-days. 207 (12.7%) cases of various complications were recorded, with an incidence of 1.67 per 1000 catheter days. The most common complications were catheter-related thrombi (n = 139, 8.6%), followed by exudate (n = 42, 2.6%), catheter related blood stream infection (CRBSI) (n = 8, 0.5%), catheter blockage (n = 5, 0.3%) and catheter exfoliation (n = 5, 0.3%), local infection at insertion site (n = 3, 0.2%), severe skin allergy (n = 2, 0.1%). The most common site of thrombi was subclavian vein which account for 87.1% (121/139). 22 cases (22/139, 15.8%) found thrombi in two or more vessels at the same time. Multivariate analysis showed that underlying disease, position of the catheter tip, secondary adjustment of CVC position, the value of D-Dimer all closely related to catheter-related thrombi. Conclusions: Catheter-related thrombi was one of the most common complications in CVC patients. Reducing the chance of secondary adjustment, using X-ray to locate the tip of the CVCs, and regular monitoring of vascular ultrasound and D-dimer during catheterization are essential for timely detection and prevention of thrombi, especially for cancer patients with higher risk of thrombi.

Chlorhexidine-impregnated dressing for the prophylaxis of central venous catheter-related complications: a systematic review and meta-analysis

BackgroundSeveral randomized controlled trials (RCTs) evaluated the role of Chlorhexidine-impregnated dressing for prophylaxis of central venous catheter (CVC) related complications, but the results remained inconsistent, updated meta-analyses on this issue are warranted.MethodsA meta-analysis on the RCTs comparing Chlorhexidine-impregnated dressing versus other dressing or no dressing for prophylaxis of central venous catheter-related complications was performed. A comprehensive search of major databases was undertaken up to 30 Dec 2018 to identify related studies. Pooled odd ratio (OR) and mean differences (MDs) with 95% confidence intervals (CI) were calculated using either a fixed-effects or random-effects model. Subgroup analysis was performed to identify the source of heterogeneity, and funnel plot and Egger test was used to identify the publication bias.ResultsA total of 12 RCTs with 6028 patients were included. The Chlorhexidine-impregnated dressings provided significant benefits in reducing the risk of catheter colonization (OR = 0.46, 95% CI: 0.36 to 0.58), decreasing the incidence of catheter-related bloodstream infection (CRBSI) (OR = 0.60, 95% CI: 0.42 to 0.85). Subgroup analysis indicated that the Chlorhexidine-impregnated dressings were conducive to reduce the risk of catheter colonization and CRBSI within the included RCTs with sample size more than 200, but the differences weren’t observed for those with sample less than 200. No publication bias was observed in the Egger test for the risk of CRBSI.ConclusionsChlorhexidine-impregnated dressing is beneficial to prevent CVC-related complications. Future studies are warranted to assess the role and cost-effectiveness of Chlorhexidine-impregnated dressings.

Is ultrasound guided syringe-free method more efficient for saphenous vein catheterization? A prospective randomized controlled study

Aim: Syringe-free is a novel technique without making blood aspiration with a syringe and by pushing forward the guide wire after verifying that the needle is inside the vein. In this study, we aimed to compare the vein intervention time between the ultrasound-guided syringe-free technique and the ultrasound-guided technique requiring syringe and aspiration procedures (classic technique), and also the success and complication rates of the first application. Methods: A prospective randomized controlled study was designed to compare ultrasound-guided syringe-free and ultrasound-guided classic technique in patients performed saphenous vein catheterization between June 2018 and September 2018. Demographic data, the period passed until a successful catheterization, the time for the needle to enter to the vein and the needle intervention number and complications are recorded. Results: 75 patient were enrolled in the study. There were no differences between demographical data in the patients (p&gt;0.05). Vein puncture time were similar in each group (p=0.750). In the ultrasound-guided syringe-free group the catheterization time is determined to be significantly shorter (p=0.003). In the syringe-free method, it is determined that the successful catheterization number is higher at first try, but the difference is not determined to be significant (p=0.370). In both groups, central venous catheter-related complications were not observed during or after the procedure.Conclusion: In conclusion, an ultrasound-guided syringe-free approach can a decrease the duration of saphenous vein catheterization and allows the operator to perform the whole procedure with ultrasound guidance without interruptions. This method can be used as an advantageous and practical method for experienced operators.
