Effect of using static ultrasound technique on peripherally inserted central catheters' insertion success rate in neonates in a neonatal intensive care unit.

BACKGROUND

Peripheral insertion of central catheters can be difficult in neonates. We compared the success rates of peripherally inserted central catheters by two methods of using static ultrasound and traditional technique (vein visualization and palpation) in neonates.

MATERIALS AND METHODS

In a prospective randomized, controlled trial, 52 neonates with birth weight lower than 1500 g in a level 3 neonatal intensive care unit were enrolled. Neonates were randomized to undergo peripherally inserted central catheter placement using a traditional technique (n = 27) versus static ultrasound-guided technique (n = 25). In the ultrasound group, vein localization was performed and the skin overlying the target vessel was marked. Insertion of catheter was then immediately performed. We recorded and compared success rates in the groups.

RESULTS

Success rate after the first attempt was 68% in ultrasound group and 60% in traditional group. These rates for the second attempt were 50% and 40%, respectively. The overall success rates after two attempts were 84% and 76% in ultrasound and traditional groups, retrospectively (P = 0.24).

CONCLUSIONS

There was no significant difference between the two groups regarding PICC success rates, probably because in the present study, most of the subjects were premature neonates whose vasculature was visually detectable.
