TL;DR

This retrospective single-centre cohort study of 676 PICC episodes in 601 newborn infants found no significant difference in central PICC tip identification with versus without a radiopaque agent. Weekly serial radiographs demonstrated that PICC tips predominantly migrate outward over their entire in situ duration.

A radiopaque agent was used in 590 of 676 episodes. There was no significant difference in the proportion of central PICC tip positions between the radiopaque agent used group (83%) and the not used group (85.8%; P=0.51). Serial radiographs revealed that PICCs predominantly migrate outward over their entire in situ duration, and the odds of tips remaining central decreased with longer dwell time (adjusted OR 0.93; 95% CI 0.92–0.95). Inward migration was identified in only 23 of 643 episodes (3.6%), occurring exclusively on radiographs obtained on or before day 7. The findings suggest routine radiopaque agent use may not be necessary and that weekly surveillance radiographs can identify PICC migration.

ABSTRACT

Background Controversy exists regarding the use of a radiopaque agent to identify peripherally inserted central catheter (PICC) tip positions in newborn infants and of serial radiography to monitor PICC tip migration. Objective To investigate the roles of (1) the injection of a radiopaque agent to identify PICC tip position and (2) the performance of weekly radiography to monitor PICC migration. Materials and methods This retrospective single-centre cohort study included newborn infants who received a PICC between 1 January 2016 and 31 December 2020. A radiopaque agent was injected to identify PICC tip position and radiographs were performed weekly to detect PICC migration. Results We identified 676 PICC episodes in 601 infants. A radiopaque agent was used for 590 of these episodes. There was no difference in the proportion of central PICC tip positions based on radiopaque agent use status (490/590, 83% for the radiopaque agent used group versus 73/85, 85.8% for the radiopaque agent not used group, P =0.51). Irrespective of the site of PICC insertion, outward migration was observed for most centrally placed PICCs over their entire in situ duration. Inward migration was identified in 23 out of 643 PICC episodes (3.6%) only on radiographs obtained on or before day 7. Based on serial radiographs, the odds for PICC tips remaining in a central position were lower the longer the PICC remained in situ (adjusted odds ratio-OR 0.93; 95% confidence interval 0.92–0.95). There was no difference in PICC migration between side and limb of insertion. Conclusion PICC tips can be identified without injection of a radiopaque agent. Serial radiographs identified PICC migration over the in situ duration. This study has implications for reducing exposure to a radiopaque agent and ongoing migration surveillance practices.
