Placement of peripherally inserted central catheters in neonates: A retrospective study.

Abstract

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).
