Agitated saline contrast to delineate central venous catheter position in neonates

Abstract

Objective

Central venous catheter (CVC) insertion is required for the management of sick neonates. Ultrasonography/targeted neonatal echocardiography (TNE) with/without normal saline (NS) flush is used to identify CVC position. The present study compared the visibility and safety of agitated saline (AS) with normal saline (NS) flush.

Study design

This prospective interventional study included 110 CVC insertions, both umbilical venous catheterization (UVC) and peripherally inserted central catheterization (PICC). Catheter position was monitored by real-time TNE.

Results

Overall visibility of catheter tip (combined UVC and PICC) was significantly better in AS (n = 55) compared with NS group (n = 55) [48/55 (87.2%) vs. 28/55 (50.9%); p < 0.0001]. Time to detect catheter tip by AS push was significantly less than that of NS push. There was no difference in the amount of saline flush required with either method. No major adverse effect was observed.

Conclusions

AS push can be used as a safe method to delineate CVC position in neonates.
