Application of ultrasound monitoring for evaluation of neonatal peripherally inserted central catheter tip localization in newborns / 中华实用儿科临床杂志

ABSTRACT

Objective@#To investigate the value of ultrasound in the localization of peripherally inserted central catheter (PICC) in neonates.@*Methods@#A retrospective analysis of the PICC catheterization was conducted at Department of Neonatology, Beijing Chaoyang District Maternal and Child Healthcare Hospital from June 2017 to December 2018.The ultrasound monitoring was performed immediately after PICC catheterization.The probe was placed into the midline position of the lower xiphoid or the subclavian parasternal line for scanning, and it would be the PICC if a high-echo " equal sign" was observed by ultrasound.It was believed that the PICC was successfully placed when ultrasound detected that the PICC tip was located in the junction of inferior vena cava or superior vena cava in the right atrium.@*Results@#(1)Among 112 infants with PICC catheterization, 103 cases (92.0%) were accurately placed, 9 cases (8.0%) were not placed in the ideal site, among them, 2 cases were too deep, 4 cases were too shallow and 3 cases were catheter heterotopia.The tip position was accurate after the readjustment under ultrasound monitoring in those patients whose the first ultrasound showed the tip position was not ideal.(2)The PICC indwelling time was as short as 2 days (removed due to severe arrhythmia) and as long as 56 days with an average of (15.1±10.7) days.(3)The catheter-related complications occurred in 3 cases with an incidence of 2.7%.@*Conclusions@#Using ultrasound to determine the PICC tips position is accurate and reliable, which is worthy of extensive application in the neonatal wards.
