目的:探讨腰麻或硬外麻下肛门周围疾病术后尿潴留的预防措施。方法:将纳入试验的患者随机分成观察组和对照组,观察组于术中减少补液量以及术后6 h内将补液速度控制在30~50滴/min,对照组不严格控制术中补液量及术后按照正常输液速度补液。结果:观察组于术后2 h内患者的迫切排尿感与对照组经卡方检验无差异(P>0.05);但术后3、4、5、6、78、h的观察指标与对照组有统计学差异(P<0.05)。结论:结合术式,术中减少输液量及术后尿潴留高发时段内减慢输液速度来预防术后尿潴留的方法,简单、有效。
Objective: To investigate the preventive measures of postoperative urinary retention after spinal or epidural anesthesia. Methods: The patients included in the trial were randomly divided into observation group and control group. In the observation group, intraoperative fluid volume was reduced and the rate of fluid replacement was controlled to 30-50 drops / min within 6 hours after operation. The control group did not strictly control intraoperative fluid volume And follow-up in accordance with the normal infusion rate rehydration. Results: The urinary urgency of patients in observation group within 2 h after operation was not significantly different from that in control group (P> 0.05). However, the indexes of observation at 3, 4, 5, 6, There was a significant difference (P <0.05). Conclusion: It is simple and effective to prevent postoperative urinary retention by combining operative procedures, decreasing intraoperative infusion volume and slowing infusion rate during postoperative high incidence of urinary retention.
