小剂量麻醉药联合控制液体量预防痔瘘术后尿潴留的效果观察

Effects of A Small Amount Anaesthetic with Controlling Fluid Volume in the Prevention of Urinary Retention after Operation of Hemorrhoids and Fistula

目的探讨小剂量麻醉药联合控制液体量对预防痔瘘术后尿潴留的效果。方法将200例手术患者随机分为实验组和对照组,对照组按常规0.5%布比卡因2mL(10mg)行腰麻,术前禁食、水6h,术后不控制液体量;实验组在常规护理的基础上用0.5%布比卡因1mL(5mg)行腰麻,术前禁食、水6h,术后控制液体量于250mL内。结果 实验组和对照组患者术后自然排尿、诱导后排尿及尿潴留有显著性差异(P<0.05)。结论 小剂量麻醉药联合控制液体量可预防和减少痔瘘术后尿潴留的发生。

Objective To study the joint control of a small amount of liquid anesthetic dose in preventing postoperative urinary re- tention effect of hemorrhoid. Methods 200 cases of surgical patients were randomLy divided into experimental and control group, control group 0.5% bupivacaine at normal 2mL（10mg） for spinal anesthesia,preoperative fasting,water, 6h, after surgery does not con- trol the amount of liquid;The experimental group based on the routine care of 0.5% bupivacaine lmL （5mg） for spinal anesthesia, preoperative fasting, water, 6h , after controlling the amount of fluid in 250mL. Results The experimental group and control group patients after natural voiding,voiding and urinary retention after the induction of a significant difference（P〈0.05）. Conclusion Low dose combined control the volume of liquid anesthetic can prevent postoperative urinary retention and reduce the occurrence of hemorrhoids.
