研究目的:

比较布比卡因脂质体与罗哌卡因在痔疮术后局部浸润麻醉中的镇痛效果VAS评分 评估布比卡因脂质体是否通过缓释技术延长术后镇痛窗口,减少阿片类药物使用需求。  

Objectives of Study:

Compare the analgesic effects of bupivacaine liposomes and ropivacaine in local infiltration anesthesia after hemorrhoidectomy using VAS scores to assess whether bupivacaine liposomes can prolong the postoperative analgesia window through sustained-release technology and reduce the need for opioid use.

随机方法(请说明由何人用什么方法产生随机序列):

由不参与麻醉管理与术中及术后随访的研究者,采用SPSS16.0 软件生成随机化数字表,以1:1的比例将患者随机分为2组:实验组(R组)和对照组(C组)。

Randomization Procedure (please state who generates the random number sequence and by what method):

Researchers who were not involved in anesthesia management and intraoperative and postoperative follow-up used SPSS16.0 software to generate a randomized number table. Patients were randomly divided into two groups at a ratio of 1:1: the experimental group (Group R) and the control group (Group C).
