Background: Mechanical factors are primary complications that justify early removal of a peripherally inserted central catheter, and thrombotic catheter occlusion is the most critical mechanical complication associated with loss of device functionality. Studies have investigated these factors in adult patients, but findings are not directly applicable to newborns. Therefore, systematic reviews focusing on this population are necessary for consolidated evidence to aid clinical practice.
Aims: This study aims to evaluate the efficacy of intermittent heparin washing versus 0.9% sodium chloride solution for preventing occlusion in newborns with peripherally inserted central catheters.
Methods: We will use the PubMed, Embase, Scopus, Web of Science, Cochrane Central Register of Controlled Trials, CINAHL, and Clinical Trial Databases for article search, without language or publication periods restrictions. Randomized clinical trials evaluating the use of intermittent heparin washing versus 0.9% sodium chloride solution in newborns with peripherally inserted central venous catheters will be included. The primary outcome will be peripherally inserted central catheter occlusion. Two reviewers will independently screen the studies, based on the inclusion criteria, extract the data for each included study and assess the risk of bias using the Cochrane risk of bias tool. The data will be synthesized using the Review Manager software (RevMan 5.4.1). To classify the strength of the evidence of results, we will use the Grading of Recommendations Assessment, Development and Evaluation Working Group (GRADE). The review was registered with PROSPERO (registration number CRD42021281509).
Expected results: We expect that this study would reveal the best method for preventing catheter occlusion in newborns with peripherally inserted central catheters.
