title: Wound infiltration with plain bupivacaine as compared with bupivacaine fentanyl mixture for postoperative pain relief after abdominal surgery.
abstract: OBJECTIVE
  To compare the efficacy of wound infiltration with Bupivacaine or Bupivacaine with fentanyl for post operative analgesia.
  
  
  BACKGROUND
  The role of Bupivacaine and fentanyl mixture as wound infiltration for post operative analgesia is less explored in human subjects.
  
  
  METHODS
  This prospective, randomized included 60 ASA grade I, II, and III patients in the age group of 20-75 years of age. The patients were randomized into two groups of 30 patients each: Group A received wound infiltration with a solution containing 0.5% bupivacaine (2 mg/kg), while, Group B received infiltration with a solution containing fentanyl 25 μg added to 0.5% bupivacaine (2 mg/kg).
  
  
  RESULTS
  None of the patients in both groups had unbearable incisional pain but addition of fentanyl to 0.5% bupivacaine reduced analgesic consumption in the postoperative period (P<0.05).
  
  
  CONCLUSIONS
  Addition of opioids to local anesthetics results in better postoperative analgesia and reduced opioid requirement post operatively.
