Adjuvants to bupivacaine for single shot caudal block in children.
This study entitled was conducted to compare the effects of addition of tramadol to bupivacaine over addition of clonidine to bupivacaine as a single shot caudal block in children.
Sixty children of ASA grade I and II in the age group of 2-12 years coming for various infra-umbilical surgeries were included.
They were divided into two groups of 30 each. Group BC received caudal bupivacaine 0.25% 0.5ml/kg with clonidine 2 mcg/kg Group BT received caudal bupivacaine 0.25% 0.5 ml/kg with tramadol 2 mg/kg. The main parameters studied were hemodynamic changes, duration of post-operative analgesia and incidence of adverse effects.
The results of continuous variables are given as mean ± SD and proportion as percentage. The difference between the two groups was assessed by student's - test and chi-square test.
The mean duration of post-operative analgesia in group BT was statistically significant ( <0.001), reducing the requirement of analgesics in group BT. There was no difference in sedation score, nausea, vomiting, urinary retention.
The present study demonstrated that caudal administration of bupivacaine 0.25% 0.5 ml/kg with tramadol 2 mg/kg resulted in superior analgesia with longer duration of action and reduced requirement of analgesics in first 24 hours postoperatively when compared with 0.25% bupivacaine 0.5 ml/kg with clonidine 2 mcg/kg.
布比卡因用于儿童单次骶管阻滞的辅助药物。
本研究旨在比较在儿童单次骶管阻滞中,布比卡因添加曲马多与添加可乐定的效果。
纳入60例年龄在2至12岁、ASA分级为I级和II级、因各种脐下手术前来就诊的儿童。
他们被分为两组,每组30例。BC组接受0.25%布比卡因0.5ml/kg加可乐定2μg/kg的骶管注射;BT组接受0.25%布比卡因0.5ml/kg加曲马多2mg/kg的骶管注射。研究的主要参数包括血流动力学变化、术后镇痛持续时间和不良反应发生率。
连续变量的结果以均值±标准差表示,比例以百分比表示。两组间的差异通过学生t检验和卡方检验进行评估。
BT组术后镇痛的平均持续时间具有统计学意义(P<0.001),减少了BT组对镇痛药的需求。镇静评分、恶心、呕吐、尿潴留方面无差异。
本研究表明,与0.25%布比卡因0.5ml/kg加可乐定2μg/kg相比,0.25%布比卡因0.5ml/kg加曲马多2mg/kg骶管给药可产生更优的镇痛效果,作用持续时间更长,且术后24小时内镇痛药需求量减少。
