Introduction: Fentanyl is added commonly to local anaesthetic administrated in the extra dural space to improve analgesia in the postoperative period. The addition of fentanyl produced only slight change in the quality and duration of analgesia after administration of 2% lidocaine with epinephrine for a short surgical procedure or after administration of 0.125% bupivacaine. Material & Method: Fifty patients, ASA physical status I-II, 18 years of age or older, undergoing surgery of the upper limb, were recruited.two groups (n=25) were investigated: Group–A: Patients received 30ml 1.5% Lidocaine with Adrenaline (1:200,000), 10ml Bupivacaine 0.5%.Group–B: Patients received 30ml 1.5% Lidocaine with Adrenaline (1:200,000), 10ml Bupivacaine 0.5%  with  fentanyl 50 microgram added to it. Results and Conclusion: The present study concluded that addition of fentanyl to local anaesthetic mixtures in brachial block delay the onset, but prolong duration of motor and sensory anesthesia, and improves quality of analgesia without affecting hemodynamic stability and without added complications.
