title: Effect of Addition of Fentanyl to Xylocaine Hydrochloride in Brachial Plexus Block by Supraclavicular Approach.
abstract: OBJECTIVE
  This study was designed to quantitatively compare the effects of 1.5% xylocaine with 1.5% xylocaine and fentanyl (1 μg/kg) mixture for supraclavicular brachial plexus block.
  
  
  METHODS
  Sixty patients between the age group of 20-60 and scheduled for upper limb surgery were divided into two groups (xylocaine group and xylocaine plus fentanyl group). After performing supraclavicular brachial plexus block, an assessment was made for onset of analgesia, duration and degree of analgesia, block intensity, and for any other side effects.
  
  
  RESULTS
  Mean duration of analgesia is Group I is 2.1 h and in Group II is 8.1 h; a four-fold increase in duration of analgesia.
  
  
  CONCLUSIONS
  Addition of fentanyl to xylocaine for supraclavicular brachial plexus block has no significant effect on onset or quality of analgesia, but duration of analgesia is significantly prolonged.
