Hess S, Poryo M, Ruckes C, Papan C, Ehrlich A, Ebrahimi-Fakhari D, Bay JS, Wagenpfeil S, Simon A, Meyer S. Assessment of an umbilical venous catheter dwell-time of 8-14 days versus 1-7 days in very low birth weight infacts (UVC - You Will See): a pilot single-center, randomized controlled trial. Early Hum Dev 2023; 179:105752. [PMID: 36958105 DOI: 10.1016/j.earlhumdev.2023.105752] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 03/09/2023] [Accepted: 03/10/2023] [Indexed: 03/25/2023]
Abstract
BACKGROUND Umbilical venous catheters (UVCs) are used for central vascular access in preterm infants, but controversy exits with regard to the optimum dwell-time. PATIENTS AND METHODS Prospective, randomized controlled trial at a level III University neonatal intensive care unit (NICU), comparing a UVC dwell-time of 1-7 days (control group) to 8-14 days (intervention group) in very low birth weight (VLBW) infants. PRIMARY OUTCOME PARAMETER Number of infants requiring additional peripherally inserted central catheters (PICC) after removal of UVC. SECONDARY OUTCOME PARAMETERS Total number of central lines (CL = UVC and PICCs) until time point of full enteral feeds (130-160 mL/kg/d), total number of intravenous vascular catheters, number of CL-associated complications (infection, thrombosis/emboli, organ injury, secondary CL dislocation), number of X-rays for assessment of CL positioning, and days of therapy (DOT) (teicoplanin) for CL-associated blood stream infections (CLABSI). RESULTS Of 116 patients screened for eligibility, 63 patients were enrolled - control group: 31 infants, mean gestational age (GA) 280 weeks (standard deviation (SD) 2.6 weeks), mean birth weight (BW) 988.9 g (SD 322.0 g); intervention group: 32 infants, mean GA 285 weeks (SD 3.0 weeks), mean BW 1078.9 g (SD 324.6 g). In the control group, 28 infants required additional PICCs versus 16 in the intervention group (p < 0.001); total number of CLs: control group n = 58 versus intervention group n = 28; p < 0.001, and the total number of venous vascular devices was also significantly higher in the control group (109 versus 61; p = 0.04). No significant differences were seen with regard to CL-associated complications (p = 0.09). The number of X-rays for assessment of correct CL-position significantly lower in the intervention group (144 versus 96; p = 0.03). In the intervention group, length of hospital stay was significantly shorter (88.1 (SD: 35.3 days) versus 68.1 (SD: 32.6 days); p = 0.03) and GA significantly lower at discharge from the hospital (404: SD: 33 weeks) versus 385: SD: 25 weeks; p = 0.02. No differences existed with regard to neonatal morbidities and mortality at 36 weeks gestational age. CONCLUSIONS A longer UVC dwell-time of up to 14 days significantly decreased the number of painful invasive vascular procedures and radiation exposure, and shortened the length of the hospital stay. The findings of our pilot study should be confirmed in a larger, multi-center RCT with the primary focus on catheter-associated complications.

Abstract
Intracardiac thrombi in preterm infants are not common but may lead to fatal outcomes. Predisposing and risk factors include small vessel size, hemodynamic instability, immaturity of the fibrinolytic system, indwelling central catheters and sepsis. In this paper, we present our own experience with a case of a catheter-related right atrial thrombus in a preterm infant, which was successfully treated with an aspiration thrombectomy. Then, we review the literature on intracardiac thrombosis in preterm infants: epidemiology, pathophysiology, clinical signs, echocardiographic diagnostic features and treatment options are discussed.

Incidence of umbilical vein catheter-associated thrombosis of the portal system: A systematic review and meta-analysis. World J Hepatol 2021; 13:1802-1815. [PMID: 34904047 PMCID: PMC8637679 DOI: 10.4254/wjh.v13.i11.1802] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Revised: 08/31/2021] [Accepted: 10/14/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The use of umbilical venous catheters (UVCs) in the perinatal period may be associated with severe complications, including the occurrence of portal vein thrombosis (PVT).
AIM To assess the incidence of UVC-related PVT in infants with postnatal age up to three months.
METHODS A systematic and comprehensive database searching (PubMed, Cochrane Library, Scopus, Web of Science) was performed for studies from 1980 to 2020 (the search was last updated on November 28, 2020). We included in the final analyses all peer-reviewed prospective cohort studies, retrospective cohort studies and case-control studies. The reference lists of included articles were hand-searched to identify additional studies of interest. Studies were considered eligible when they included infants with postnatal age up to three months with UVC-associated PVT. Incidence estimates were pooled by using random effects meta-analyses. The quality of included studies was assessed using the Newcastle-Ottawa scale. The systematic review was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines.
RESULTS Overall, 16 studies were considered eligible and included in the final analyses. The data confirmed the relevant risk of UVC-related thrombosis. The mean pooled incidence of such condition was 12%, although it varied across studies (0%-49%). In 15/16 studies (94%), diagnosis of thrombosis was made accidentally during routine screening controls, whilst in 1/16 study (6%) targeted imaging assessments were carried out in neonates with clinical concerns for a thrombus. Tip position was investigated by abdominal ultrasound (US) alone in 1/16 (6%) studies, by a combination of radiography and abdominal US in 14/16 (88%) studies and by a combination of radiography, abdominal US and echocardiography in 1/16 (6%) studies.
CONCLUSION To the best of our knowledge, this is the first systematic review specifically investigating the incidence of UVC-related PVT. The use of UVCs requires a high index of suspicion, because its use is significantly associated with PVT. Well-designed prospective studies are required to assess the optimal approach to prevent UVC-related thrombosis of the portal system.

Abstract
OBJECTIVE To determine the incidence of adverse events (AEs) associated with umbilical catheters in the neonatal population. STUDY DESIGN Systematic review and meta-analysis of observational studies and randomized controlled trials published between 2010 and 2020. RESULTS In total 14,226 umbilical venous catheters (UVCs) and 4228 umbilical arterial catheters (UACs) were included. Overall, 13.4% of UVCs were associated with an AE (95% CI: 10.1-17.0) or 2.4 per 1000 catheter days (95% CI: 1.8-3.0). UACs had an AE rate of 9% (95% CI: 5.9-12.8) or 0.87 per 1000 catheter days (95% CI: 0.4-1.3). UVC malposition was the most common (41.7% [95% CI: 27.6-56.5]). Local injury from UAC taping was the most common AE in one study. CONCLUSIONS Umbilical catheters have a high incidence of AEs. Research into accurate methods of tip verification, tip surveillance, and securement is required.

Abstract
INTRODUCTION Adverse events associated with umbilical catheters include malposition, bloodstream infections, thrombosis, tip migration, and extravasation, resulting in loss of vascular access and increased risk of morbidity and mortality. There is a need for greater understanding of risk factors associated with adverse events to inform safe practice. OBJECTIVES The aim of the study was to summarise the existing evidence regarding risk factors for umbilical catheter-related adverse events to inform the undertaking of future research. REVIEW METHOD USED A scoping review of peer-reviewed original research and theses was performed. DATA SOURCES The US National Library of Medicine National Institutes of Health, Embase, EMcare, and ProQuest Dissertations and Theses were the data sources. REVIEW METHODS Informed by the Joanna Briggs Institute Reviewer's Manual, all types of original research studies reporting adverse events published in English from 2009 to 2020 were eligible for inclusion. Studies where umbilical artery catheter and umbilical venous catheter data could not be extracted separately were excluded. RESULTS Searching identified 1954 publications and theses, 1533 were excluded at screening, and 418 were assessed for eligibility at full text. A total of 89 studies met the inclusion criteria. A range of potential risk factors for umbilical arterial and venous catheters were identified. Longer dwell time and prematurity were associated with increased risk of bloodstream infection and thrombosis in cohort studies. Case studies detailed analogous factors such as insertion techniques and lack of catheter surveillance during dwell warrant further investigation. CONCLUSIONS We identified a vast range of patient, device, and provider risk factors that warrant further investigation. There was a lack of large cohort studies and randomised controlled trials to demonstrate the significance of these risk factors. Improvement in methods to ensure correct catheter tip location and to detect adverse events early is essential. In addition, policy needs to be developed to guide clinicians in catheter surveillance measures to reduce the risk of adverse events.

Abstract
Aim: Umbilical venous catheters are frequently used in the neonatal period. The incidence of umbilical venous catheter-related thrombosis is between 1.3% and 43% in ultrasound scans. This study aimed to determine the incidence and risk of portal vein thrombosis in patients who were hospitalized in the neonatal intensive care unit and underwent umbilical venous catheter insertion. Material and Methods: Premature infants (≤32 gestational weeks) who were hospitalized in a Level III neonatal intensive care unit and underwent umbilical vein catheter placement between 2016 and 2018, were included in the study. The demographic data, clinical risk factors for thrombosis, number of catheter days, catheter locations, times of detection of thrombosis using Doppler ultrasonography, treatment methods and durations, thrombosis follow-up and examinations were obtained retrospectively from the electronic patient files. Results: Ninety-six patients whose complete data could be reached were enrolled in the study. The mean gestational age of the patients was found as 29±2 weeks and the mean birth weight was 1353±369 g. Portal vein thrombosis was detected in 13.5% (n=13) of the patients. Five of the cases of portal vein thrombose were complete occlusion and eight were partial occlusion. All patients with complete occlusion and six patients with partial occlusion were treated with low-molecular-weight heparin for a mean duration of 31±13.8 days. Thrombosis disappeared in 7–120 days in all patients. A thrombophilia mutation was detected in six patients with thrombosis, four of whom had the PAI-1 4G / 5G mutation. Conclusion: Portal vein thrombosis which has a significant place among the causes of portal hypertension in childhood, is mostly asymptomatic in the neonatal period and cannot be recognized clinically. It is important to screen and follow up patients with umbilical vein catheters using Doppler ultrasonography in terms of PVT after catheter removal to prevent long-term complications.

Abstract
INTRODUCTION This study aimed to determine the risk factors for subclinical umbilical catheter-related thrombosis (UCRT) and its association with clinical morbidities. MATERIALS AND METHODS In infants without any symptoms associated with umbilical catheterization, the presence of thrombosis was monitored using abdominal ultrasonography within 1 week after umbilical catheter removal. The association between UCRT and the clinical variables was analyzed by comparing the groups with and without UCRT. RESULTS UCRT occurred in 26 (19.0%) of 137 infants. The relative incidence rate of thrombosis was 12.3% at the umbilical artery and 21.7% at the umbilical vein. However, the type of umbilical vessels with a catheter was not associated with thrombosis (P = 0.095). Subclinical UCRT was associated with high serum calcium concentration in the multivariate analysis (95% confidence interval, 1.26-15.32; P = 0.020). UCRT was resolved within 3 weeks in 13 infants (50.0%), although the thrombosis persisted for up to 2 months in 2 infants (7.7%). We found no significant association between the subclinical UCRT and the neonatal morbidities in preterm infants. CONCLUSIONS Though a rare cause of thrombosis, hypercalcemia should be considered in the assessment of infants with subclinical UCRT, and calcium levels should be routinely checked in infants with umbilical catheters.

Abstract
BACKGROUND Umbilical venous catheters (UVCs) are associated with thrombus formation. Most studies on thrombosis in infants with UVCs focus on only one part of the route, and none assessed a control group of infants without UVCs. OBJECTIVE To determine the incidence and location of thrombi in infants after umbilical catheterisation and compare this with a control group of infants without umbilical catheters. DESIGN Prospective observational study with serial ultrasonography of the UVC route from the umbilico-portal confluence to the heart. Ultrasonography was performed until day 14 after catheterisation in cases and day 14 after birth in controls. RESULTS Thrombi in the UVC route were detected in 75% (30/40) of infants with UVCs in the study group, whereas no thrombi were detected in the control group of infants without UVCs (0/20) (p<0.001). Six thrombi (20%) were located in the right atrium. Most of these were also partly present in the ductus venosus. Six thrombi (20%) were located in the ductus venosus only, and in 12 infants (40%), the thrombus was at least partly located in the umbilico-portal confluence. Thrombi persisted after UVC removal in 25/30 cases. Two infants with thrombotic events were treated with low-molecular-weight heparin and resolution was found. In the other 23 infants managed expectantly, 2 died due to necrotising enterocolitis, 1 was lost to follow-up and in 20 spontaneous regression was seen. CONCLUSIONS Thrombotic events occur frequently in infants after umbilical catheterisation. Most thrombi were asymptomatic and regressed spontaneously with expectant management. Routine screening for thrombi in UVCs is therefore not advised.

Abstract
Heparin has typically been used as a flushing or infusion solution for vascular lines in daily practice. However, several clinical trials have yielded controversial results about the benefits of heparin in maintaining peripheral venous catheters. The present meta-analysis was conducted to evaluate the efficacy of heparin on the patency profiles and complications in peripheral intravenous catheters. PubMed, Embase and Cochrane Central Register of Controlled Trials were searched up to February 2016 for randomized controlled trials comparing heparin with placebo in maintaining peripheral intravenous catheters. Additional studies were retrieved from the reference lists of identified articles. In total 32 eligible studies were included, from which the pooled standard mean difference (SMD), relative risk (RR) and corresponding 95% confidence interval (CI) were calculated. The use of heparin as a continuous infusion significantly prolonged the duration of patency (SMD, 0.90; 95% CI, 0.48-1.32; P<0.001), reduced rates of infusion failure (RR, 0.83; 95% CI, 0.76-0.92; P<0.001) and occlusion (RR, 0.82; 95% CI, 0.69-0.98; P<0.05) in a peripheral intravenous catheter. However, there were no significant changes in the duration of patency and infusion failure when heparin was used intermittently as a flushing solution, although a significantly decreased risk of occlusion was observed in this setting (RR, 0.80; 95% CI, 0.66-0.98; P<0.05). Furthermore, the risk of phlebitis was significantly decreased by both continuous infusion (RR, 0.66; 95% CI, 0.58-0.75; P<0.01) and intermittent flushing (RR, 0.70; 95% CI, 0.56-0.86; P<0.01) of heparin in peripheral venous catheters. In conclusion, the use of heparin as continuous infusion in peripheral intravenous catheters improved the duration of patency, reduced infusion failure and phlebitis, whereas heparin as intermittent flushing showed more benefits in ameliorating phlebitis rather than in patency profiles.

Abstract
CONTEXT The failure and complications of central venous access devices (CVADs) result in interrupted medical treatment, morbidity, and mortality for the patient. The resulting insertion of a new CVAD further contributes to risk and consumes extra resources. OBJECTIVE To systematically review existing evidence of the incidence of CVAD failure and complications across CVAD types within pediatrics. DATA SOURCES Central Register of Controlled Trials, PubMed, and Cumulative Index to Nursing and Allied Health databases were systematically searched up to January 2015. STUDY SELECTION Included studies were of cohort design and examined the incidence of CVAD failure and complications across CVAD type in pediatrics within the last 10 years. CVAD failure was defined as CVAD loss of function before the completion of necessary treatment, and complications were defined as CVAD-associated bloodstream infection, CVAD local infection, dislodgement, occlusion, thrombosis, and breakage. DATA EXTRACTION Data were independently extracted and critiqued for quality by 2 authors. RESULTS Seventy-four cohort studies met the inclusion criteria, with mixed quality of reporting and methods. Overall, 25% of CVADs failed before completion of therapy (95% confidence interval [CI] 20.9%-29.2%) at a rate of 1.97 per 1000 catheter days (95% CI 1.71-2.23). The failure per CVAD device was highest proportionally in hemodialysis catheters (46.4% [95% CI 29.6%-63.6%]) and per 1000 catheter days in umbilical catheters (28.6 per 1000 catheter days [95% CI 17.4-39.8]). Totally implanted devices had the lowest rate of failure per 1000 catheter days (0.15 [95% CI 0.09-0.20]). LIMITATIONS The inclusion of nonrandomized and noncomparator studies may have affected the robustness of the research. CONCLUSIONS CVAD failure and complications in pediatrics are a significant burden on the health care system internationally.

Abstract
BACKGROUND Heparin intermittent flushing is a standard practice in the maintenance of patency in central venous catheters. However, we could find no systematic review examining its effectiveness and safety. OBJECTIVES To assess the effectiveness of intermittent flushing with heparin versus 0.9% sodium chloride (normal saline) solution in adults with central venous catheters in terms of prevention of occlusion and overall benefits versus harms. SEARCH METHODS The Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched December 2013) and the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 11). Searches were also carried out in MEDLINE, EMBASE, CINAHL and clinical trials databases (December 2013). SELECTION CRITERIA Randomised controlled trials (RCTs) in adults 18 years of age and older with a central venous catheter (CVC) in which intermittent flushing with heparin (any dose with or without other drugs) was compared with 0.9% normal saline were included. No restriction on language was applied. DATA COLLECTION AND ANALYSIS Two review authors independently selected trials, assessed trial quality and extracted data. Trial authors were contacted to retrieve additional information, when necessary. MAIN RESULTS Six eligible studies with a total of 1433 participants were included. The heparin concentrations used in these studies were very different (10-5000 IU/mL), and follow-up varied from 20 days to 180 days. The overall risk of bias in the studies was low. The quality of the evidence ranged from very low to moderate for the main outcomes (occlusion of CVC, duration of catheter patency, CVC-related sepsis, mortality and haemorrhage at any site).Combined findings from three trials in which the unit of analysis was the catheter suggest that heparin was associated with reduced CVC occlusion rates (risk ratio (RR) 0.53, 95% confidence interval (CI) 0.29 to 0.94). However, no clear evidence of a similar effect was found when the results of two studies in which the unit of analysis was the participant were combined (RR 0.21, 95% CI 0.03 to 1.70), nor when findings were derived from one study, which considered total line accesses (RR 1.08, 95% CI 0.84 to 1.40). Furthermore, results for other estimated effects were found to be imprecise and compatible with benefit and harm: catheter duration in days (mean difference (MD) 0.41, 95% CI -1.29 to 2.12), CVC-related thrombosis (RR 1.22, 95% CI 0.74 to 1.99), CVC-related sepsis (RR 1.02, 95% CI 0.34 to 3.03), mortality (RR 0.77, 95% CI 0.45 to 1.32) and haemorrhage at any site (RR 1.37, 95% CI 0.49 to 3.85). AUTHORS' CONCLUSIONS We found no conclusive evidence of important differences when heparin intermittent flushing was compared with 0.9% normal saline flushing for central venous catheter maintenance in terms of efficacy or safety. As heparin is more expensive than normal saline, our findings challenge its continued use in CVC flushing outside the context of clinical trials.

J Thromb Haemost 2014; 12:1096-109. [PMID: 24801495 PMCID: PMC4107177 DOI: 10.1111/jth.12598] [Citation(s) in RCA: 87] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2014] [Accepted: 04/29/2014] [Indexed: 12/21/2022]
Abstract
OBJECTIVES In preparation for a pediatric randomized controlled trial on thromboprophylaxis, we determined the frequency of catheter-related thrombosis in children. We also systematically reviewed the pediatric trials on thromboprophylaxis to evaluate its efficacy and to identify possible pitfalls in the conduct of these trials. PATIENTS/METHODS We searched MEDLINE, EMBASE, Web of Science and the Cochrane Central Register for Controlled Trials for articles published until December 2013. We included cohort studies and trials on patients aged 0-18 years with central venous catheters who underwent active surveillance for thrombosis with radiologic imaging. We estimated the pooled frequency of thrombosis and the pooled risk ratio (RR) with thromboprophylaxis by using a random effects model. RESULTS From 2651 articles identified, we analyzed 37 articles with 3128 patients. The pooled frequency of thrombosis was 0.20 (95% confidence interval [CI] 0.16-0.24). In 10 trials, we did not find evidence that heparin-bonded catheters (RR 0.34; 95%CI 0.01-7.68), unfractionated heparin (RR 0.93; 95% CI 0.57-1.51), low molecular weight heparin (RR 1.13; 95% CI 0.51-2.50), warfarin (RR 0.85; 95%CI 0.34-2.17), antithrombin concentrate (RR 0.76; 95% CI 0.38-1.55) or nitroglycerin (RR 1.53; 95%CI 0.57-4.10) reduced the risk of thrombosis. Most of the trials were either not powered for thrombosis or were powered to detect large, probably unachievable, reductions in thrombosis. Missing data on thrombosis also limited these trials. CONCLUSIONS Catheter-related thrombosis is common in children. An adequately powered multicenter trial that can detect a modest, clinically significant reduction in thrombosis is critically needed. Missing outcome data should be minimized in this trial.
