快速交换试验对腹膜透析导管功能障碍的诊断价值

Diagnostic value of rapid exchange test in patients with peritoneal dialysis catheter dysfunction

纳入2020年6月至2022年8月中国医科大学附属第一医院收治的怀疑腹膜透析(腹透)导管功能障碍的患者共36例,腹透管功能正常的对照组5例。男22例,女19例,年龄(45±21)岁。对照组与腹透管功能障碍组快速期引流量分别为(2086±65)、(1181±637)ml,总引流时长分别为(15.2±1.3)、(38.3±14.9)min,腹透管功能障碍组较对照组的快速期引流量减少、总引流时长延长(均P<0.05)。与腹透管移位组比较,腹透管堵塞组新一袋灌入时长延长,快速期引流量减少,总引流时长延长,负超量增加(均P<0.05)。快速交换试验可早期诊断腹透导管功能障碍,鉴别导管功能障碍类型。

A total of 36 patients with suspected peritoneal dialysis(PD)catheter dysfunction in the First Hospital of China Medical University from June 2020 to August 2022 were included,and five patients with normal PD catheter were also included as the control group.There were 22 males and 19 females,and aged(45±21)years.The volume of rapid-phase drainage in the control and dysfunction groups was(2086±65)and(1181±637)ml,and the total drainage time was(15.2±1.3)and(38.3±14.9)min,respectively.The volume of rapid-phase drainage in the dysfunction group was reduced and the total drainage time was longer than that in the control group(both P<0.05).Compared with group with PD catheter migration,the duration of new bag instillation was prolonged,the drainage volume in the rapid-phase was reduced,the total drainage duration was prolonged,and the ultrafiltration volume was decreased in the group with PD catheter obstruction(all P<0.05).The rapid exchange test can provide an early preliminary diagnosis of PD catheter dysfunction and identify the type of catheter dysfunction.
