Abstract :

Background : Regional anesthesia is a recommended technique for upper limb surgeries with better postoperative profile. The aim of our study was to evaluate the effect of fentanyl addition to 0.5% bupivacaine and Lignocaine 2% with epinephrine (1:200,000) in supraclavicular achial plexus block on the onset, duration and quality of block for upper extremity surgeries with lesser side effects and easy administration.

Materials and Methods: This study comprised 50 cases of ASA grade-l & II between the age group of 15 to 45 years undergoing upper limb surgeries. Group c (Control Group) consisted of 25 patients and was given 10 ml of 0.5% Bupivacaine (1 mg/kg) and 18 ml of 2% Lignocaine with adrenaline (7 mg 1 kg) + 2 ml normal saline (Total volume 30 ml). Group F (Fentanyl Group) 25 patients10 ml of Bupivacaine 0.5% (1 mg/kg) +2 ml Fentanyl (100 microgram) and 18 ml of 2% lignocaine with adrenaline (Total volume 30 ml)

Results : onset of sensory blockade in control group was within 10-15 min., in fentanyl group with in 16-20 min.Mean time of onset of sensory blockade was 13.12 + 3.952 in control group and 14.96 + 4.04 min in Fentanyl group. onset of motor blockade in group C within 5-10 minutes and in group F within 5-10 minutes.The mean onset of motor blockade in group C was 10.96+3.32 min. and group F was 11.04+3.36 min. Duration of analgesia in control group wass within 241-360 min and in Fentanyl group within 601-720 min.The mean duration of analgesia in control group is 320.60 + 68.61 min and in Fentanyl group that is 663.60 + 109.12 minThe mean duration of motor blockade in control group is 260.20 + 77.059 min and Fentanyl group is 350.40 + 109.006 min.

Conclusion: When fentanyl was mixed with the local anaesthetic drug it caused prolongation of duration of analgesia for supraclavicular achial plexus block.There was no significant difference on onset of sensory and motor blockade in both groups.There was no significant occurrence of complication in both groups. Insignificant vital parameters changes throughout the study in both the groups.
