Abstract

Abstract:

Objective To investigate the postoperative complications of the “pull” technique for peritoneal tube extubation in peritoneal dialysis (PD) patients and its influencing factors, and to further optimize the “pull” technique to reduce the incidence of complications. Methods From September 1, 2018 to October 31, 2023, 98 PD patients in peritoneal dialysis centers of four hospitals, including Zhongshan Hospital Xiamen University, and 339 PD patients extubated using the “pull” technique reported at home and abroad were analyzed. Literatures with a small sample size or unclear descriptions were excluded. The clinical data were compared. Results Complications occurred in 13 of the 98 patients in the dialysis center. Multivariate logistic regression analysis showed that body mass index (BMI) was an independent risk factor for the complications after the “pull” technique for peritoneal cathether extubation (P<0.05). Compared with the cases reported in literatures, the proportion of PD catheter rupture and abdominal wall bleeding in our study group was significantly larger (P<0.05). There were 7 cases of PD catheter rupture out of 98 patients, which may be related to the number of traction, traction angle and traction intensity. Among the 98 patients, there were 8 cases reporting the distance between the outer cuff and the skin outlet less than 2 cm or the infection of the outlet and the outer cuff before extubation, and no complications were observed after the modified “pull” technique for peritoneal cathether extubation. Due to repeated infection and prolapse of shallow cuff in 7 cases, Seldinger puncture catheterization combined with the “pull” technique for peritoneal cathether extubation was used to replace the PD catheter. Conclusion The “pull” technique for peritoneal catheter extubation is a safe and reliable technique with few and treatable complications.

Key words: peritoneal dialysis, “pull”technique, complication, root cause analysis
