术后持续镇痛患者拔除尿管时机的探讨

Study of the appropriate time to remove urinary catheter in patients with continuous analgesia after operation

目的探讨术后拔除尿管的适宜时间。方法98例腹部手术患者随机分为实验组(n=50)与对照组(n=48)。实验组于术后第3d拔除镇痛泵后5h拔除尿管,对照组于术后第3d拔除镇痛泵后1h拔除尿管。结果实验组有1例发生尿潴留,对照组则有10例发生尿潴留。两组患者排尿成功率的差异有统计学意义(P<0.05)。结论患者在术后第3d拔除镇痛泵后5h拔除尿管,可有效防止尿潴留的发生。

To study the appropriate time to remove urinary catheter in patients with continuous analgesia after operation. Methods Ninety eight patients after operation were randomly divided into treatment group (n=50) and control group (n=48). The urinary catheter was removed 5 hours after the analgesic pump was taken off on the third day after operation in the treatment group and 1 hour after the analgesic pump was taken off in the control group. Results One patient in the treatment group and 10 patients in the control group suffered from urine retention. The difference of the rate of successful urinating between the two groups is statistically significant (P < 0.05). Conclusion Urine retention can be prevented if the urinary catheter is removed 5 hours after the analgesic pump is taken off on the third day after operation.
