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.
