Hemorrhoid is one of the most common surgical diseases occurring in the anorectal region. In this study, we evaluated the effect of ischiorectal fossa block on alleviating post hemorrhoidectomy pain.
In this study, 90 patients suffering from hemorrhoids were evaluated. They were randomly divided into 3 groups. The first group had no block, the second group an ischiorectal block with placebo (normal saline), and the third group a preemptive ischiorectal block with bupivacaine. Postoperative variables such as pain intensity, pethidine consumption, nausea, and vomiting were compared between the groups.
The postoperative pain score in group 1 was 8.5 ± 1.3 and 8.1 ± 0.9 (P = NS) in group 2. The post operative analgesic demand was 3.1 ± 1.5 and 3.3 ± 1.8 hours in groups 1 and 2, respectively (P = NS). The post operative pain score and analgesic demand were 4.2 ± 2.1 and 9.3 ± 2.7 hours, respectively, in group 3 (P < 0.0001).
Preemptive ischiorectal block reduces the posthemorrhoidectomy pain and opioid demand.
痔疮是肛门直肠区域最常见的手术疾病之一。在本研究中,我们评估了坐骨直肠窝阻滞对缓解痔切除术后疼痛的效果。
本研究共评估了 90 例痔疮患者。他们被随机分为 3 组。第 1 组无阻滞,第 2 组坐骨直肠阻滞用安慰剂(生理盐水),第 3 组行超前性坐骨直肠阻滞用布比卡因。比较各组之间的术后变量,如疼痛强度、哌替啶消耗量、恶心和呕吐。
第 1 组的术后疼痛评分为 8.5 ± 1.3,第 2 组为 8.1 ± 0.9(P = NS)。第 1 组和第 2 组的术后镇痛需求分别为 3.1 ± 1.5 和 3.3 ± 1.8 小时(P = NS)。第 3 组的术后疼痛评分和镇痛需求分别为 4.2 ± 2.1 和 9.3 ± 2.7 小时(P < 0.0001)。
超前性坐骨直肠阻滞可减轻痔切除术后疼痛和阿片类药物需求。
