Abstract
Backround: Brachial plexus block is a common technique to provide anaesthesia for surgery of arm, forearm and hand. It can be obtained by conventional method by eliciting paraesthesia, use of a peripheral nerve stimulator or use of ultrasound scanning device. The aim of this study is to compare the efficacy of supra clavicular brachial plexus block by using nerve stimulator method and USG guided method. The procedure time, volume of drug and adverse effects in upper limb orthopaedic surgeries performed under supraclavicular brachial plexus blockade using ropivacaine as local anaesthetic
Methods: After ethical committee approval and informed consent from patients, a comparative observational study was performed on patients scheduled for upper limb orthopaedic surgeries under supraclavicular plexus block.
This study was done among two group of patients belonging to ASA 1 and 2, of age 30-70yrs Both the groups of patients were comparable with regard to age, sex and weight. They were allocated into two groups using computer generated randomization. Group 1 received 15mL of 0.5 % ropivacaine brachial plexus block using ultrasound guided and Group 2 received 25ml of 0.5 % ropivacaine in brachial plexus block using nerve stimulator.
Results; Datas were analysed using spss software using the student ‘t test And chi square test and p <0.05 was considered as significant. Observation were represented both graphically and numerically
Conclusion ; Observation of this study shows that supra clavicular brachial plexus block using ultrasound guided method is an improved nerve block technique due to visualization of nerves with more success, decreased complication rate, and less time consuming , smaller volume of local anaesthetic agent required, as compared to nerve stimulator
Keywords: suprclavicular brachial plexus block, ultrasound, nerve stimulator, ropivacaine.
