Background: Peripherally inserted central catheters (PICCs) are commonly used in neonatal intensive care units for extended intravenous nutrition and therapy. The selection of PICCs insertion sites can significantly influence insertion outcomes and neonatal safety., Aim: This study aimed to determine the most suitable insertion site in the lower extremities for neonatal PICCs., Study Design: A retrospective case note review was conducted on PICCs inserted through lower extremity (LE) sites in a 40-bed tertiary-level neonatal intensive care unit at a university teaching hospital. The dates when data were accessed for research purposes were from June 2019 to June 2022. In total, 223 neonates were identified as having had PICCs, with 254 catheters inserted in the lower extremities. The STROBE checklist guided the reporting of this study., Results: Neonates underwent PICC insertion via the LE vein, with an overall complication rate of 13.4% and a one-attempt success rate of puncture of 86.2%. The rates of complications, catheter occlusion, and catheter-related infection in the PICC group with insertion through the great saphenous vein were significantly lower than those in the femoral vein group (p < .05). The success rate was significantly higher than that in the femoral vein group (p < .05). Additionally, the incidence of total complications and catheter occlusion complications with PICC insertion via the right LE was significantly lower than that with insertion via the left LE (p < .05)., Conclusion: Our study suggested that, when feasible, the saphenous vein in the right LE could be the most suitable insertion site for neonatal PICCs., Relevance to Clinical Practice: These findings provide insights into the complications, indwelling time, and safety of neonatal PICCs in different LE sites, serving as a valuable reference for clinical practice. This study was retrospective in nature, and all staff involved obtained approved access to patient clinical data. Ethical approval was granted by the Ethics Committee of Xiangya Hospital, Central South University (registry number 2022010001)., (© 2024 British Association of Critical Care Nurses.)

Background: Catheter-related thrombosis is a common complication of the peripherally inserted central catheter (PICC) in neonates, leading to unintended tube removal and significantly affecting neonatal health and safety. Despite widespread reporting on the estimated occurrence and factors contributing to neonatal PICC-related thrombosis, these findings have not been synthesized., Objectives: The purpose of this study was to determine the incidence and risk factors of neonatal PICC-related thrombosis., Design: Systematic literature review and meta-analysis., Methods: Two independent researchers systematically explored multiple databases-such as PubMed, Medline, Embase and the Cochrane Library-from their inception until October 2023. Our study aggregates and scrutinizes studies specifically addressing the incidence and risk factors of neonatal PICC-related thrombosis. Employing the RevMan 5.3 software, a meta-analysis was executed to determine the incidence of both thrombosis and odds ratios (OR), accompanied by their respective 95% confidence intervals (CI) for the risk factors., Results: A total of 327 articles were screened, and data from 24 studies were used in synthesis. Neonatal PICC-related thrombosis incidence varied from 0.23% to 17.91%. The pooled incidence was 2% (95% CI: 1%-2%; I 2  = 94%; p < .0001). The study identified 12 risk factors, including insertion sites in the lower extremities (OR = 0.22; 95% CI: 0.09-0.56; p = .001), gestational age <28 weeks, abdominal pathology, fresh frozen plasma by day 5 > 50 mL/kg, PICC tip location (proximal placement), two lumens, three lumens, prolonged hospital stay, infection, mothers' use of anticoagulants, patients with cardiac insufficiency and being twin-to-twin transfusion syndrome donor., Conclusions: The analysis indicates an overall pooled incidence of neonatal PICC-related thrombosis of 2%. Twelve factors were identified as risks associated with neonatal PICC-related thrombosis. Understanding the risk factors can provide evidence-based recommendations for improving awareness, control and treatment and better nursing management., Relevance to Clinical Practice: This systematic review and meta-analysis illuminates the incidence and risk factors linked to neonatal PICC-related thrombosis, delivering essential insights pivotal for clinical decision-making and enhancing patient care within neonatal health care settings., (© 2024 British Association of Critical Care Nurses.)
