Intracardiac Thrombi in Preterm Infants-A Case Study and Review of the Literature. Diagnostics (Basel) 2023; 13:diagnostics13040764. [PMID: 36832252 PMCID: PMC9955841 DOI: 10.3390/diagnostics13040764] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 02/12/2023] [Accepted: 02/13/2023] [Indexed: 02/19/2023] Open
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.

Pediatr Int 2021; 63:561-564. [PMID: 32964580 DOI: 10.1111/ped.14476] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 08/24/2020] [Accepted: 09/07/2020] [Indexed: 01/15/2023]
Abstract
BACKGROUND Our peripherally inserted central venous catheter (PICC) management plan for neonates previously included routine inspection for swelling and induration of the insertion site of a PICC using palpation. However, we discontinued routine palpation from July 13, 2018, owing to a peculiarly high incidence of PICC-related phlebitis. The aim of this study was to prove that routine palpation was the cause of PICC-related phlebitis. METHODS We retrospectively reviewed medical records of infants who were admitted to the neonatal intensive care unit and underwent PICC placement from January 2018 to January 2019. The infants were classified into palpating (before July 13, 2018) and non-palpating (after or on July 13, 2018) groups. We analyzed and compared the incidence of PICC-related phlebitis in the two groups. RESULTS Phlebitis related to PICC was more frequently observed in the palpating group (10/29 infants, 34.5%) than in the non-palpating group (1/31, 3.2%) (P = 0.002). After discontinuation of routine palpating in PICC management, the frequency of non-scheduled removal of the PICC due to phlebitis decreased. The indwelling period was significantly longer in the non-palpating group than in the palpating group. CONCLUSIONS Our results suggest that mechanical stimulation using palpation of the insertion site was the cause of PICC-related phlebitis, resulting in early non-scheduled removal.

Abstract
Peripherally inserted central catheter (PICC) has been widely used in the neonatal intensive care unit (NICU) in recent years, but there are potential risks for complications related to PICC. Based on the current evidence in China and overseas, the operation and management guidelines for PICC in neonates were developed by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) in order to help the NICU staff to regulate the operation and management of PICC.

Abstract
UNLABELLED Peripherally inserted central catheter (PICC) and umbilical venous catheter (UVC) in terms of success rate, complications, cost and time of insertion in neonatal intensive care were compared. Neonates requiring vascular access for minimum 7 days were included. Sample size of 72 per group was determined. Trial was registered at Clinical Trials Registry of India (CTRI/2015/02/005529). Success rates of the UVC and PICC were 68.1% and 65.3%, respectively (p = 0.724). Mean (SD) time needed for PICC and UVC insertion was 34.13 (34.69) and 28.31 (17.19) min, respectively (p = 0.205). Mean (SD) cost of PICC insertion vs. UVC insertion was 60.9 (8.6) vs. 11.9 (8.7) US dollars (p < 0.0001). Commonest cause for failure of UVC was displacement [6 (8.3%)] and that for PICC was blockage [9 (12.5%)]. CONCLUSIONS UVC is a cheaper alternative to PICC, with similar success rate, short-term complications and time needed for insertion.

Abstract
OBJECTIVES To identify patient, hospital, and central venous catheter factors that may influence the use of low-dose heparin infusion for central venous catheter patency in critically ill children. DESIGN Secondary analysis of an international multicenter observational study. SETTING Fifty-nine PICUs over four study dates in 2012, involving seven countries. PATIENTS Children less than 18 years old with a central venous catheter who were admitted to a participating unit and enrolled in the completed Prophylaxis against Thrombosis Practice study were included. All overflow patients were excluded. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Of the 2,484 patients in the Prophylaxis against Thrombosis Practice study, 1,312 patients had a central venous catheter. Five hundred seven of those patients used low-dose heparin infusion. The frequency of low-dose heparin infusion was compared across various patient, hospital, and central venous catheter factors using chi-square, Mann-Whitney U, and Fisher exact tests. In the multivariate analysis, age was not a significant factor for low-dose heparin infusion use. Patients with pulmonary hypertension had decreased low-dose heparin infusion use, whereas those with active surgical or trauma diagnoses had increased low-dose heparin infusion use. All centrally inserted central venous catheters were more likely to use low-dose heparin infusion when compared with peripherally inserted central venous catheters. The Asia-Pacific region showed increased low-dose heparin infusion use, along with community hospitals and smaller ICUs (< 10 beds). CONCLUSIONS Patient, central venous catheter, and hospital factors are associated with the use of low-dose heparin infusion in critically ill children. Further study is needed to evaluate the efficacy and persistence of low-dose heparin infusion use.

Anticoagulants for the prevention and treatment of catheter-related thrombosis in adults and children on parenteral nutrition: a systematic review and critical appraisal. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2016; 15:369-377.

Abstract
BACKGROUND Patients on parenteral nutrition require a central venous access and are at risk of catheter-related thrombosis, pulmonary embolism, and vena cava syndrome. Parenteral nutrition guidelines suggest anticoagulation for the primary prevention of catheter-related thrombosis during long-term parenteral nutrition. We conducted a systematic review of the efficacy, safety and feasibility of anticoagulant use for preventing and treating catheter-related thrombosis during parenteral nutrition. MATERIALS AND METHODS We searched for interventional and observational studies on adults and children receiving systemic anticoagulants during either short- or long-term parenteral nutrition delivered via central venous access. Primary outcomes were: objectively-confirmed catheter-related thrombosis, pulmonary embolism and bleeding. Secondary outcomes were: heparin-induced thrombocytopenia, prevalence of anticoagulation, and quality of International Normalised Ratio management in vitamin K antagonist-treated patients. RESULTS We identified 1,199 studies, of which 23 were included. Seven interventional studies of short-term parenteral nutrition (adult population, n=5) were classified as low-quality: in those, intravenous unfractionated heparin did not prevent catheter-related thrombosis if compared to saline. No interventional studies were conducted in patients on long-term parenteral nutrition. Observational data were sparse, rarely focusing on anticoagulation, and overall of low quality. The reported use of anticoagulants was between 22 and 66% in recent multicentre cohorts. DISCUSSION The amount and quality of data in this area are very suboptimal: most studies are outdated and involved heterogeneous populations. Currently, there is insufficient evidence to allow conclusions to be reached regarding the efficacy and safety of anticoagulants in this setting.

Abstract
BACKGROUND Preterm birth remains the major risk factor for the development of intraventricular haemorrhage, an injury that occurs in 25% of very low birth weight infants. Intraventricular haemorrhage is thought to be venous in origin and intrinsic thromboses in the germinal matrix are likely to play a triggering role. Heparin activates antithrombin and promotes the inactivation of thrombin and other target proteinases. The administration of anticoagulants such as heparin may offset the increased risk of developing intraventricular haemorrhage and may also reduce the risk of developing parenchymal venous infarct, a condition known to complicate intraventricular haemorrhage. OBJECTIVES To assess whether the prophylactic administration of heparin reduces the incidence of germinal matrix-intraventricular haemorrhage in very preterm neonates when compared to placebo, no treatment, or other anticoagulants. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2015), MEDLINE (1996 to 22 November 2015), EMBASE (1980 to 22 November 2015) and CINAHL (1982 to 22 November 2015), applying no language restrictions. We searched the abstracts of the major congresses in the field (Perinatal Society of Australia and New Zealand and Pediatric Academic Societies) from 2000 to 2015. SELECTION CRITERIA Randomised controlled trials, quasi-randomised controlled trials and cluster trials comparing the administration of early, i.e. within the first 24 hours of life, heparin in very preterm infants (gestational age < 32 weeks). DATA COLLECTION AND ANALYSIS For each of the included trials, two authors independently extracted data (e.g. number of participants, birth weight, gestational age, dose of heparin, mode of administration, and duration of therapy, etc.) and assessed the risk of bias (e.g. adequacy of randomisation, blinding, completeness of follow up). The primary outcomes considered in this review are intraventricular haemorrhage, severe intraventricular haemorrhage and neonatal mortality. MAIN RESULTS Two randomised controlled trials enrolling a total of 155 infants met the inclusion criteria of this review. Both trials compared low-dose heparin to the same solution without heparin in very preterm newborns requiring umbilical catheterisation. No trials were identified that specifically studied the use of heparin in infants at risk of germinal matrix-intraventricular haemorrhage.We found no differences in the rates of intraventricular haemorrhage (typical RR 0.93, 95% CI 0.61 to 1.41; typical RD -0.03, 95% CI -0.17 to 0.12; 2 studies, 155 infants; I² = 57% for RR and I² = 65% for RD), severe intraventricular haemorrhage (typical RR 1.01, 95% CI 0.46 to 2.23; typical RD 0.00, 95% CI -0.11 to 0.11; 2 studies, 155 infants; I² = 0% for RR and I² = 0% for RD) and neonatal mortality (typical RR 0.69, 95% CI 0.28 to 1.67; typical RD -0.04, 95% CI -0.14 to 0.06; 2 studies, 155 infants; I² = 28% for RR and I² = 50% for RD). We judged the quality of the evidence supporting these findings as very low (rates of intraventricular haemorrhage) and low (severe intraventricular haemorrhage and neonatal mortality) mainly because of limitations in the study designs and the imprecision of estimates. We found very few data on other relevant outcomes, such as bronchopulmonary dysplasia, pulmonary haemorrhage and patent ductus arteriosus; and no study assessing long-term outcomes (e.g. neurodevelopmental disability). AUTHORS' CONCLUSIONS There is very limited data on the effect of prophylactic administration of heparin on the incidence and severity of IVH in very preterm neonates. Both the identified trials used heparin in the context of maintaining umbilical line patency and not specifically as an agent to prevent germinal matrix-intraventricular haemorrhage. Given the imprecision of our estimates, the results of this systematic review are consistent with either a benefit or a detrimental effect of heparin and do not provide a definitive answer to the review question. Limited evidence is available on other clinically relevant outcomes.

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.

Abstract
BACKGROUND Parenteral nutrition (PN) is a high-alert medication available for patient care within a complex clinical process. Beyond application of best practice recommendations to guide safe use and optimize clinical outcome, several issues are better addressed through evidence-based policies, procedures, and practices. This document provides evidence-based guidance for clinical practices involving PN prescribing, order review, and preparation. METHOD A systematic review of the best available evidence was used by an expert work group to answer a series of questions about PN prescribing, order review, compounding, labeling, and dispensing. Concepts from the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) format were applied as appropriate. The specific clinical guideline recommendations were developed using consensus prior to review and approval by the American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) Board of Directors. The following questions were addressed: (1) Does education of prescribers improve PN ordering? (2) What is the maximum safe osmolarity of PN admixtures intended for peripheral vein administration? (3) What are the appropriate calcium intake and calcium-phosphate ratios in PN for optimal neonatal bone mineralization? (4) What are the clinical advantages or disadvantages of commercially available premade ("premixed") multichambered PN formulations compared with traditional/customized PN formulations? (5) What are the clinical (infection, catheter occlusion) advantages or disadvantages of 2-in-1 compared with 3-in-1 PN admixtures? (6) What macronutrient dosing limits are expected to provide for the most stable 3-in-1 admixtures? (7) What are the most appropriate recommendations for optimizing calcium (gluconate) and (Na- or K-) phosphate compatibility in PN admixtures? (8) What micronutrient contamination is present in parenteral stock solutions currently used to compound PN admixtures? (9) Is it safe to use the PN admixture as a vehicle for non-nutrient medication delivery? (10) Should heparin be included in the PN admixture to reduce the risk of central vein thrombosis? (11) What methods of repackaging intravenous fat emulsion (IVFE) into smaller patient-specific volumes are safe? (12) What beyond-use date should be used for (a) IVFE dispensed for separate infusion in the original container and (b) repackaged IVFE?

Abstract
OBJECTIVES To evaluate the frequency of central venous catheter (CVC)-related thrombi detected by routine surveillance ultrasound, and to assess whether positive findings had an impact on management or outcomes. STUDY DESIGN All neonates in a tertiary neonatal intensive care unit who had a CVC inserted for >14 days underwent routine surveillance ultrasound biweekly between January 2003 and December 2009. Data were reviewed retrospectively. RESULTS Although all neonates were asymptomatic at time of surveillance ultrasound, 645 of the total 1333 CVCs inserted in 1012 neonates underwent surveillance ultrasound, and thrombi were detected in 69 (10.7%). The CVCs with thrombi were more likely to be removed for nonelective reasons compared with CVCs without thrombi (59% vs 38%; P = .001; OR, 2.4, 95% CI 1.4-3.9). A total of 955 surveillance ultrasounds were performed to detect and monitor 69 CVCs with thrombi. The majority of thrombi were nonocclusive and nonprogressive. A change in management occurred in 8 cases of CVC-related thrombi (12%), or 1% of all screened cases. An average of 14 ultrasounds were required to detect and monitor 1 CVC with thrombus, at a cost of $951 per CVC with thrombus and $8106 per case of CVC-related thrombi with a change in treatment. CONCLUSION Asymptomatic thrombi were detected in a significant proportion of CVCs by routine surveillance ultrasound. There were significant costs, but infrequent changes to patient management.

Abstract
Peripherally Inserted Central Catheter (PICC) blockage rate was audited over a two month period on the Trauma & Orthopaedics ward at our District General Hospital. A 70% (five out of seven) PICC blockage rate was observed. High blockage rates lead to potential treatment complications, delays in delivery of treatment, increase in costs, and reduction in patient satisfaction. The factors contributing to the significant blockage rate include, long and contradictory PICC care guidelines, no information sheets in the patient notes, lack of training and awareness about care of, and flushing of, PICC lines, and lack of accountability for PICC flushing. Our project aimed to achieve a greater rate of PICC patency. We produced one succinct and comprehensive PICC care guideline, carried out staff training sessions, introduced a sticker reminding staff to flush the PICC line after use, and introduced a prescription of weekly heparin saline and PRN saline flushes (for monitoring and accountability). We used questionnaires to assess competency of hospital staff pre-teaching (doctors 6%, nurses 0%), and post-teaching (doctors 70%, nurses 38%). Blockage rate data post-intervention is pending. Education improved awareness of guidelines amongst staff and we anticipate that the proposed interventions will translate into reduced blockage rates, improving patient outcomes and reducing costs.

Abstract
O cateter central de inserção periférica é tecnologia comum empregada na terapia intravenosa de neonatos. Trata-se de revisão integrativa, cujo objetivo foi investigar e analisar as evidências disponíveis na literatura acerca da temática. As bases de dados pesquisadas foram Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) e Biblioteca Nacional de Medicina dos Estados Unidos (PubMed). Resultados apontam lacunas no que tange à população neonatal; conhecimento insuficiente dos profissionais quanto indicações (n=1); e variados temas sobre uso de anticoagulantes (n=6), comparação com outros cateteres (n=4), diagnóstico por imagem (n=2), dor (n=2), infecção relacionada a cateter e sua prevenção (n=7), entre outros fatores. Conclui-se que há necessidade de atualização profissional, evidências científicas de fácil acesso e publicações nacionais.

Abstract
OBJECTIVE To identify factors associated with complications necessitating unplanned removal of peripherally inserted central venous catheters (PICCs) in neonates. STUDY DESIGN A before-and-after comparison following the exclusion of heparin from continuous infusions through PICCs placed by a designated team. Duration of use was assessed during epochs immediately preceding and following the practice change. Multivariable logistic regression was performed to identify independent risk factors associated with unplanned catheter removal. RESULT We analyzed 189 PICC placements with heparin (epoch 1) and 188 with no heparin (epoch 2) added to infusions. Rates of complication (23.7 vs 17.2 per 1000 catheter days) and median durations of use (7 vs 8 days) did not differ significantly between the epochs. Non-central position of the catheter tip, use of dual lumen catheters and placement through the cephalic vein were independently associated with complications (each P<0.05). CONCLUSION In neonates requiring short-term intravenous access, heparin may be safely omitted from continuous infusions without compromising catheter usability.

Abstract
BACKGROUND Neonates and children differ from adults in physiology, pharmacologic responses to drugs, epidemiology, and long-term consequences of thrombosis. This guideline addresses optimal strategies for the management of thrombosis in neonates and children. METHODS The methods of this guideline follow those described in the Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines: Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines. RESULTS We suggest that where possible, pediatric hematologists with experience in thromboembolism manage pediatric patients with thromboembolism (Grade 2C). When this is not possible, we suggest a combination of a neonatologist/pediatrician and adult hematologist supported by consultation with an experienced pediatric hematologist (Grade 2C). We suggest that therapeutic unfractionated heparin in children is titrated to achieve a target anti-Xa range of 0.35 to 0.7 units/mL or an activated partial thromboplastin time range that correlates to this anti-Xa range or to a protamine titration range of 0.2 to 0.4 units/mL (Grade 2C). For neonates and children receiving either daily or bid therapeutic low-molecular-weight heparin, we suggest that the drug be monitored to a target range of 0.5 to 1.0 units/mL in a sample taken 4 to 6 h after subcutaneous injection or, alternatively, 0.5 to 0.8 units/mL in a sample taken 2 to 6 h after subcutaneous injection (Grade 2C). CONCLUSIONS The evidence supporting most recommendations for antithrombotic therapy in neonates and children remains weak. Studies addressing appropriate drug target ranges and monitoring requirements are urgently required in addition to site- and clinical situation-specific thrombosis management strategies.

Abstract
Heparin prophylaxis (HP) is commonly used for prevention of central venous catheter (CVC)-related complications among pediatric intensivists, yet efficacy of this therapy is unknown. We conducted a survey of pediatric intensivists and their experiences with HP. A total of 96 responses were received. Almost half of the respondents regularly used HP in patients with CVCs, yet most were unsure of its benefit. The majority of respondents claimed to experience no adverse effects; the complications that were reported to occur were related to bleeding or suspected heparin-induced thrombocytopenia (HIT). Overall, participants felt CVC-associated HP was safe in pediatric critical illness, while acknowledging the paucity of compelling data.

Abstract
OBJECTIVES To summarize a) epidemiology of arterial and venous thromboembolism, pulmonary embolism, and deep venous thrombosis in children; b) the risk factors for thrombosis in the pediatric intensive care unit; c) diagnostic techniques for arterial/venous thromboembolism; and d) the current recommendations for management and prevention of thromboembolic disease in critically ill children. DATA SOURCE Literature review, using National Library of Medicine PubMed and the following terms: arterial, venous thromboembolism; deep venous thrombosis; pulmonary embolism; thrombosis; as well as citations of interest from these articles. STUDY SELECTION Both pediatric and adult literature addressing thrombotic disease were reviewed. DATA EXTRACTION AND SYNTHESIS Articles were chosen for more extensive discussion when containing prospective studies, guidelines for practice, or data in critically ill patients. When data in children were unavailable, applicable data in adults were referenced. Due to the paucity of data in critically ill children, available adult and pediatric data were combined with institutional experience to provide suggestions for current practice and future inquiry. CONCLUSIONS Increasing awareness regarding the recognition and current approaches to management and prevention of thromboembolic disease in children is needed among pediatric intensivists, so outcome of these life-threatening processes might be improved.

Abstract
OBJECTIVE To evaluate the effect of low-dose heparin on duration of peripherally inserted percutaneous central venous catheter (PCVC) patency and catheter occlusion. STUDY DESIGN Our research was a prospective, randomized, controlled, double-blind clinical study including 246 eligible neonates with PCVCs. It was conducted at the neonatal intensive care unit (NICU) of Diyarbakir Children's Hospital between 1 February 2007 and 31 October 2008. In the heparin group (n=118), the total parenteral nutrition (TPN) solutions contained heparin, which was infused at a rate of 0.5 IU kg⁻¹ h⁻¹ . The no-heparin group (n=121) received TPN fluids without heparin. RESULT In the heparin group, the duration of catheter patency was longer than that of the no-heparin group reaching a statistically significant difference (12.4 ± 4.5 vs 9.7 ± 4.0, P<0.0001). In the heparin group, the proportion of patients completing the TPN therapy successfully was higher than in the no-heparin group (P=0.0001; relative risk (RR): 3.32 (95% confidence interval (CI): 1.92 to 5.73)) also demonstrating a statistically significant difference. The rate of catheter occlusion among infants in the heparin group was smaller (P=0.0001; RR: 3.44 (95% CI: 1.92 to 6.44)). There were no statistically significant differences between the two groups in the incidence of other catheter-related problems. The length of the occluded catheter outside the skin, TPN infusion rate and catheter duration time were found to be the factors associated with catheter occlusion. Heparin prevented catheter occlusion with a mechanism unrelated to these factors. CONCLUSION In neonates with PCVCs, low-dose continuous infusion of heparin (0.5 IU kg ⁻¹h⁻¹ within TPN fluids is an effective measure in terms of reducing catheter occlusion, allowing successful completion of the therapy, without increasing adverse effects. Furthermore, this effect of heparin may occur independently via occlusion-related factors that we evaluated in the study.

Abstract
Peripheral venous catheters (PVC) are the most frequently used invasive devices in hospitals. Up to 70% of patients require a peripheral venous line during their hospital stay, and conservative estimates suggest that PVC days account for 15-20% of total patient days in acute care hospitals. Most published studies focus on thrombophlebitis and address the issue of scheduled catheter change, but there is still no consensus on the optimal time point for PVC change, or whether catheter replacement is required at all. Although PVC-associated catheter-related bloodstream infections (PVC-BSI) are far more serious than thrombophlebitis, few studies address this issue, and a large multicentre trial is lacking. Some studies on thrombophlebitis mention that no, or only a few, PVC-BSIs were identified, but such results must be interpreted with caution. Current data available on PVC-BSI suggest incidence density rates of 0.2-0.7 episodes per 1000 device days, which appear low when compared with other catheters. However, some studies report absolute PVC-BSI numbers in the range of central line-associated infections. It remains unclear whether PVC-BSI should be considered a serious healthcare problem or simply a very rare event. More research is needed both to capture the dimension of the problem and to provide efficient control measures.

Abstract
BACKGROUND Complications associated with peripherally placed percutaneous central venous catheters (PCVC) in neonates include mechanical complications (catheter thrombosis, occlusion or dislodgement) and infection. Strategies to prevent catheter thrombosis and occlusion include the use of heparin. However, heparin is known to be associated with complications such as bleeding and thrombocytopenia. PRIMARY OBJECTIVE To assess the effectiveness of heparin for prevention of catheter related thrombosis. SECONDARY OBJECTIVES To assess the effectiveness of heparin on catheter occlusion, duration of catheter patency, catheter related sepsis and complications associated with the use of heparin. SEARCH STRATEGY A literature search of MEDLINE, EMBASE, CINAHL from their inception to December 2007, The Cochrane Library (Issue 4, 2007) and abstracts from the annual meetings of the Pediatric Academic Societies was performed without language restrictions. SELECTION CRITERIA Randomized or quasi-randomized clinical trials of neonates where heparin infusion was compared to placebo or no treatment for prevention of any of the complications related to peripherally placed PCVC were included. DATA COLLECTION AND ANALYSIS The methodological quality of included trials was assessed using criteria for masking of randomization, masking of intervention, completeness of follow-up and masking of outcome measurement. Data on relevant outcomes were extracted and the effect size was estimated by calculating relative risk (RR), risk difference (RD) and associated 95% confidence intervals (CI). MAIN RESULTS Three randomized trials were identified. Two trials of adequate methodology met the eligibility criteria. These studies included 267 neonates. There was reduced risk of catheter occlusion (typical RR 0.28, 95% CI 0.15, 0.53, NNT 5, 95% CI 3, 8). There was no statistically significant difference in the duration of catheter patency when analyzed as continuous data; however, in one study survival analyses identified benefit with heparin (adjusted hazard ratio 0.55, 95% CI 0.36, 83); (Shah 2007). This could be due to higher incidence of elective removal of catheters in neonates at the completion of therapy in the heparin group (63% vs. 42%; p = 0.002) (Shah 2007). There was no statistically significant differences in the risk of thrombosis (typical RR 0.93, 95% CI 0.58, 1.51), catheter related sepsis (typical RR 1.96, 95% CI 0.50, 7.60), or extension of intraventricular hemorrhage (typical RR 0.87, 95% CI 0.25, 3.03) between the two groups. IMPLICATIONS FOR PRACTICE Prophylactic use of heparin for peripherally placed PCVC allows a greater number of infants to complete their intended use (complete therapy) by reducing occlusion. Evidence from this systematic review support the prophylactic use of heparin for PCVC in neonates at a dose of 0.5 IU/kg/hr. IMPLICATIONS FOR RESEARCH None of these studies was powered to evaluate a lower incidence rate of adverse events. If this therapy is adopted in routine practice, monitoring of side effects is indicated.

Abstract
OBJECTIVE To compare the effectiveness of two methods of vascular access in newborns. DESIGN Randomized controlled trial. SETTING Neonatal intensive care unit in Regional Hospital of Valdivia, Chile. PARTICIPANTS Seventy-four high-risk newborns. INTERVENTIONS Peripherally inserted central catheter and peripheral intravenous catheter. MAIN OUTCOME MEASURES Length of neonatal intensive care unit stay and incidence of sepsis and phlebitis. RESULTS/DATA ANALYSIS: There were no statistically significant differences in the length of the neonatal intensive care unit stay and in the incidence of sepsis between groups. There was a significant higher incidence of phlebitis in the peripheral intravenous catheter group. CONCLUSIONS Although there was not a significant effect of the kind of catheter on length of neonatal intensive care unit stay, the peripherally inserted central catheter is recommended because of the decreased risk of phlebitis and the decreased number of venipuncture attempts and catheters needed to complete intravenous therapy.

Abstract
BACKGROUND Mechanical and infectious complications shorten the effective duration of peripherally inserted central venous catheters. Heparin use to prevent such complications and prolong the usability of peripherally inserted central venous catheters is inconclusive. OBJECTIVE Our goal was to evaluate the effectiveness of heparin in prolonging the usability of peripherally inserted central venous catheters in neonates. DESIGN/METHODS We performed a multicenter, randomized, controlled trial of heparin infusion (0.5 U/kg per hour) versus placebo for peripherally inserted central venous catheters in neonates. The primary outcome was duration of catheter use. Secondary outcomes were occlusion, catheter-related sepsis, thrombosis, and adverse effects of heparin. To detect a 168-hour (1-week) difference in the duration of catheter use, 192 patients were needed. Kaplan-Meier and Cox regression analyses were performed. RESULTS A total of 201 neonates were enrolled (heparin group: n = 100; control group: n = 101). Baseline demographics were similar between the groups. Duration of catheter use was longer in the infants in the heparin versus the placebo group. Study center, gender, birth weight, and type and position of the catheter were not predictors of duration of catheter use. For those in the heparin versus the placebo group, the incidence of elective catheter removal (therapy completed) was 63% vs 42%, of occlusion was 6% vs 31%, of thrombosis was 20% vs 21%, and of catheter-related sepsis was 10% vs 6%, respectively. No adverse events were noted. CONCLUSIONS Heparin infusion prolonged the duration of peripherally inserted central venous catheter usability, which permitted a higher percentage of neonates to complete therapy without increasing adverse effects.

Abstract
In neonates and infants, arterial and central venous catheters are of vital importance to optimize perioperative surveillance during surgery as well as postoperative care in the intensive care unit. The insertion of umbilical venous (UVC) and umbilical arterial catheters (UAC) in neonates in the first days of life is relatively simple and associated with a low procedure-related risk. As with other centrally placed catheters, correct positioning must be verified and the catheters should not be used for more than 5-7 days. Peripherally inserted central catheters (PICC) are commonly used in neonates and can be an alternative to conventional central venous lines in older infants. In order to minimize the risk associated with catheter malposition, correct position must always be verified by appropriate imaging studies or ECG guidance. Surgically placed Broviac catheters are mainly used in patients with a long-term need for central venous access. Finally, it has been shown that adherence to strict guidelines for insertion and handling can significantly reduce catheter-associated infections.

Abstract
OBJECTIVE To determine the effects of intermittent flushing with heparin versus NaCl 0.9% solution on prevention of thrombotic events and infections in central venous catheters. METHOD A systematic review of controlled trials, randomized or not, in whose intermittent flushing with heparin versus NaCl 0.9% in central venous catheters were compared was carried out. Any publication was excluded because of patients age, country or language. Studies were identified by computerised searches (MEDLINE and CINAHL 1996-2004, EMBASE Drugs and Pharmacology 1991-2004, Cochrane Library up 2005, ISI Web of knowledge 1990-2004), clinical trials metaregister http://www. controlled-trials.commrct/mrct_info_es.asp, and scanning references. RESULTS Only two clinical trials, involving 94 patients, fulfilled inclusion criteria for obstruction. Methodological quality of trials was poor and heterogenicity was also very significant. It made impossible meta-analytical combination of results. No studies comparing heparin vs. NaCl 0.9% solution flushing in catheter-related infection prophylaxis were reported. CONCLUSIONS Poor evidence supports effectiveness of intermittent heparin flushing vs. NaCl 0.9% solution, although methodological limitations and small sample size make these findings very inconsistent. In infection prophylaxis, there is no data allowing us to conclude if heparin flushing is more effective than NaCl 0.9% solution. More randomized clinical trials are needed.

Abstract
BACKGROUND Peripherally inserted central venous catheters (PICCs) are now widely used for intermediate and long-term access in current-day health care, especially in the inpatient setting, where they are increasingly supplanting conventional central venous catheters (CVCs) placed percutaneously into the internal jugular, subclavian, or femoral veins. Data on the risk of PICC-related bloodstream infection (BSI) with PICCs used in hospitalized patients are limited. STUDY OBJECTIVES To determine the risk of PICC-related BSI in hospitalized patients. STUDY DESIGN Prospective cohort study using data from two randomized trials assessing the efficacy of chlorhexidine-impregnated sponge dressing and chlorhexidine for cutaneous antisepsis. METHODS PICCs inserted into the antecubital vein in two randomized trials during from 1998 to 2000 were prospectively studied; most patients were in an ICU. PICC-related BSI was confirmed in each case by demonstrating concordance between isolates colonizing the PICC at the time of removal and from blood cultures by restriction-fragment DNA subtyping. RESULTS Overall, 115 patients had 251 PICCs placed. Mean duration of catheterization was 11.3 days (total, 2,832 PICC-days); 42% of the patients were in an ICU at some time, 62% had urinary catheters, and 49% had received mechanical ventilation. Six PICC-related BSIs were identified (2.4%), four with coagulase-negative staphylococcus, one with Staphylococcus aureus, and one with Klebsiella pneumoniae, a rate of 2.1 per 1,000 catheter-days. CONCLUSION This prospective study shows that PICCs used in high-risk hospitalized patients are associated with a rate of catheter-related BSI similar to conventional CVCs placed in the internal jugular or subclavian veins (2 to 5 per 1,000 catheter-days), much higher than with PICCs used exclusively in the outpatient setting (approximately 0.4 per 1,000 catheter-days), and higher than with cuffed and tunneled Hickman-like CVCs (approximately 1 per 1,000 catheter-days). A randomized trial of PICCs and conventional CVCs in hospitalized patients requiring central access is needed. Our data raise the question of whether the growing trend in many hospital hematology and oncology services to switch from use of cuffed and tunneled CVCs to PICCs is justified, particularly since PICCs are more vulnerable to thrombosis and dislodgment, and are less useful for drawing blood specimens. Moreover, PICCs are not advisable in patients with renal failure and impending need for dialysis, in whom preservation of upper-extremity veins is needed for fistula or graft implantation.

Abstract
BACKGROUND Peripherally placed percutaneous central venous catheters (PCVC) are used in neonates to provide long-term vascular access. Major complications associated with these catheters include mechanical complications (catheter thrombosis, occlusion or dislodgement) and infection. Strategies to prevent catheter thrombosis and occlusion include the use of heparin. Systematic review has revealed that heparin is effective in prolonging the umbilical arterial catheter stay in neonates. However, heparin is known to be associated with complications such as bleeding and thrombocytopenia which may result in serious long-term sequelae. OBJECTIVES The primary objective is to assess the effectiveness of heparin for prevention of catheter related thrombosis. The secondary objectives are to assess the effectiveness of heparin on catheter occlusion, duration of catheter patency, catheter related sepsis and complications associated with the use of heparin. SEARCH STRATEGY A literature search was performed using the following databases: MEDLINE (1966-February 2005), EMBASE (1980-February 2005), CINAHL (1982-February 2005) and the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2005) and abstracts from the annual meetings of the Society for Pediatric Research/American Pediatric Society and Pediatric Academic Societies published in Pediatric Research (1991-2005). No language restrictions were applied. SELECTION CRITERIA Selection criteria applied to the clinical trials were: the population had to be neonates, intervention had to be heparin infusion compared to placebo or no treatment for prevention of any of the complications related to peripherally placed PCVC, the trial had to be randomized or quasi-randomized and at least one of the primary or secondary outcomes reported. DATA COLLECTION AND ANALYSIS The methodological quality of included trials was assessed using criteria for masking of randomization, masking of intervention, completeness of follow-up and masking of outcome measurement. Data on relevant outcomes were extracted and the effect size was estimated by calculating relative risk (95% CI), risk difference (95% CI) and weighted mean difference (95% CI). MAIN RESULTS Two randomized trials on the use of heparin for peripherally placed PCVC were identified . One trial (Kamala et al) of 66 neonates of adequate methodology met the eligibility criteria. There was no statistically significant differences in the incidence of thrombosis (RR 0.79, 95% CI 0.35, 1.79), occlusion (RR 0.63, 95% CI 0.22), catheter related sepsis (RR 0.89, 95% CI 0.06, 13.57), extension of intraventricular hemorrhage (RR 0.87, 95% CI 0.25, 3.03), mortality (RR 0.59, 95% CI 0.18, 1.90) or duration of catheter patency (WMD 1.50 days, 95% CI -1.35 days, 4.35 days) between heparin and no heparin groups. Another trial (Betremieux et al) was excluded due to several methodological issues: 1. randomization was at the time of umbilical catheter placement rather than later PCVC placement 2. multiple PCVC were used in some infants, with reported results based on number of catheters rather than infants. IMPLICATIONS FOR PRACTICE Prophylactic use of heparin for prevention of complications related to peripherally placed PCVC has been examined in only one randomized controlled clinical trial that was eligible for inclusion in this review. No significant differences in the incidence of thrombosis, occlusion, sepsis, mortality and duration of catheter patency were observed. With the current state of knowledge, routine use of heparin for this purpose can not be recommended. Implication for research: Increasing survival of extremely low birth weight infants may be accompanied by prolonged intravenous access for nutrition. Well designed randomized controlled trials of sufficient power to determine the benefits and risks of continuous infusion of heparin in neonates with peripherally inserted PCVC are warranted.

Abstract
PURPOSE OF REVIEW There has been a considerable amount of work in the field of parenteral nutrition over the last year. Although none of this has been truly mold-breaking, there are sufficient new directions that a review is a worthwhile exercise. RECENT FINDINGS The arguments in favor of parenteral feeding in acute pancreatitis continue to become weaker. Intravenous nutrition as an alternative to major surgery in Crohn disease should be considered. A series of new, and not so new, complications is reviewed, together with a range of means by which problems may be avoided. New approaches to the avoidance or treatment of the rare case of intravenous nutrition-associated liver disease are discussed. SUMMARY The parenteral approach remains an important method of nutritional support: recent data help to ensure its safer and more effective implementation.
