Risk factors for catheter tip displacement after ultrasound-guided umbilical vein catheterization in neonates / 医学研究生学报

ABSTRACT

Objective Catheter tip displacement (CTD) after ultrasound-guided umbilical vein catheterization (UVC) in neonates may influence the effect of treatment .This study was to investigate the risk factors for CTD . Methods This study included 159 neonates undergoing ultrasound -guided UVC in our hospital between January 2015 and June 2017.We recorded the one-time suc-cess rate of UVC and the numbers of cases of CTD and non -CTD at 7 days after UVC, and analyzed the risk factors for CTD by univari -ate and multivariate logistic regression analyses . Results Ultrasound-guided UVC was successfully performed in 106 (66.67％) of the neonatal patients, who underwent ultrasonography and thoracic and abdominal X -ray examinations 7 days later.CTD was observed in 19 (17.93％) of the 106 neonates, including 5 cases of upward shift (4.72％) and 14 cases of downward shift (13.21％), while the other 87 ( 82.07％) were non-CTD cases.Statistically significant differences were found between the CTD and non -CTD groups in the gestational age, body mass, catheter external fixation, restlessness, catheter-tending time, and catheter shifting (P<0.05).Multivariate analysis showed that the gestational age (OR =-1.315, P =0.015),body mass (OR=-1.214, P=0.019), catheter external fixation (OR =2.164, P =0.007), restlessness (OR =1.354, P =0.014), catheter-tending time (OR=1.458, P=0.012), and catheter shifting (OR=2.016, P=0.010) were the risk factors for CTD after ul-trasound-guided UVC. Conclusion There are quite a few risk factors for CTD after ultrasound -guided UVC, which can be reduced by relevant preventive measures .
