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

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 .

Comparison of the Rate of Catheter Malposition and Survival according to the Site of Catheter Tip Placement / 대한신장학회잡지

BACKGROUND: The peritoneal catheter of the continuous ambulatory peritoneal dialysis(CAPD) is patients' lifeline. A significant number of complications and catheter failures in CAPD are due to mechanical problems. We describe our retrospective experience with CAPD focusing on the rate of catheter displacement and survival according to the site of catheter tip placement in 70 cases of CAPD in Kyunghee University Hospital between November 1994 and February 2000. METHODS: We describe our retrospective experience with CAPD focusing on the rate of catheter displacement and survival according to the site of catheter tip placement in 70 cases of CAPD in Kyunghee University Hospital between November 1994 and February 2000. RESULTS: Among 70 cases of CAPD, 46 cases were right pelvic cavity tip placement and 24 cases were left. Causes of chronic renal failure(CRF) were diabetes mellitus in 29 cases(63%), hypertension in 13 cases (28%), glomerulonephritis in 4 cases(9%) in right pelvic cavity catheter tip placement and diabetes mellitus in 13(54%), hypertension in 10(42%), renal tuberculosis in 1 case(4%) left pelvic cavity catheter tip. There were no difference in causative diseases of CRF between both groups. Incidence of CAPD catheter tip displacement were 17.4%(8/46) at right and 4.2%(1/24) at left catheter(p=0.01). Methods for treatment of displacement were fluoroscopic brushing, laparoscopic manipulation and operation. Of the 9 cases, 5 case were received fluoroscopic brushing, 3 case were laparoscopic manipulation and 1 case was received operation. Other complication were peritonitis, catheter obstruction, hernia, death. Overall survival of catheter were 65%(30/46) at right and 71 %(17/24) at left catheter(p=NS). CONCLUSION: The incidence of CAPD catheter tip displacement was higher with catheter tip at the right pelvis than left(p=0.01). But there is no difference in the catheter survival.
