Clinical Study on the Application of Rapid Pressurized Flushing Combined With Lidocaine Sealing in the Management of Peritoneal Dialysis Catheter Displacement

Objective: To evaluate the clinical efficacy of rapid pressurized flushing and lidocaine sealing in managing peritoneal dialysis (PD) catheter migration. Methods: 76 PD patients who experienced catheter migration leading to drainage dysfunction between July 2021 and June 2023 were enrolled and randomly assigned to either the experimental group (n = 38) or the control group (n = 38) using a random number table method. The control group received conventional non-surgical repositioning, while the experimental group underwent rapid pressurized flushing combined with lidocaine sealing in addition to the standard approach. The primary outcomes assessed included repositioning success rate, repositioning time, treatment costs, and patient satisfaction. Results: The repositioning success rate in the experimental group was 97.37%, significantly higher than 73.68% in the control group (P < 0.01). Additionally, the experimental group exhibited a significantly shorter repositioning time, lower average treatment costs, and higher patient satisfaction than the control group (P < 0.01). Conclusion: Rapid pressurized flushing combined with lidocaine sealing is a simple, safe, and cost-effective technique with a high success rate, making it a promising non-surgical approach for PD catheter migration management. Its broad clinical applicability suggests significant potential for widespread implementation in peritoneal dialysis practice.
