Abstract: Objective To analyze the influencing factors of catheter displacement in peritoneal dialysis patients, and to provide guidance for the prevention of catheter displacement. Methods The clinical data of 173 cases of peritoneal dialysis patients treated in our hospital from January 2018 to February 2020 were retrospectively analyzed. The incidence of catheter displacement within 4 weeks after peritoneal dialysis catheterization was statistically analyzed. The general data of patients, including age, gender, primary diseases, incision location, constipation, body mass index, and catheter type were recorded. The influencing factors of catheter displacement were analyzed by univariate and multivariate analysis. Results Within 4 weeks after peritoneal dialysis catheterization, 14 out of 173 patients had catheter displacement, with the incidence of 8.09%. There was no statistically significant difference in age, gender, primary diseases, or body mass index between patients with and without catheter displacement (all P>0.05), but there were statistically significant differences in incision location, incidence of constipation, and catheter type (all P<0.05). Multivariate logistic regression model was established after logistic regression analysis. It was found that the right umbilical incision, constipation, and tube insertion were the influencing factors of catheter displacement in peritoneal dialysis patients (all OR>1, P<0.05). Conclusion Right umbilical incision, constipation, and curved tube placement will increase the risk of catheter displacement in peritoneal dialysis patients. Reasonable intervention should be implemented to reduce the incidence of catheter displacement.

摘要： 目的 分析腹膜透析置管术患者导管移位的影响因素,为预防导管移位提供指导。方法 回顾分析2018年1月至2020年2月本院收治的173例腹膜透析患者临床资料,统计患者腹膜透析置管术后4周内导管移位发生情况,统计患者的一般资料,包括年龄、性别、原发病、切口位置、便秘发生情况、体质量指数、导管类型,经单因素与多因素分析检验腹膜透析置管术患者导管移位的影响因素。结果 腹膜透析置管术后4周内,173例患者中14例发生导管移位,发生率为8.09%;发生、未发生导管移位患者的年龄、性别、原发病、体质量指数比较,差异均无统计学意义(均P>0.05);切口位置、便秘发生情况、导管类型比较,差异均有统计学意义(均P<0.05);经二元logistics回归分析,脐部右侧切口、便秘、置入曲管是腹膜透析置管术患者导管移位的影响因素(均OR>1,P<0.05)。结论 脐部右侧切口、便秘、置入曲管会提升腹膜透析置管术患者术后发生导管移位的风险,临床应据此实施合理的干预,以降低患者术后导管移位发生率。
