Spinal anesthesia with lignocaine heavy has been popular for short surgical procedures as it has predictable onset and provides dense sensory and motor block of moderate duration. To evaluate efficiency of fentanyl for prolonging action of 5% Lignocaine for Spinal anesthesia. Total 60 patients are included in this study and they are divided in to 2 group.Each group consist of 30 participants. Among them one group(Group 1) has given 2 ml 5% Lignocaine plus 1 ml normal saline while second group has given 2 ml 5% Lignocaine plus 1 ml Fentanyl (20 microgm)intrathecally to see efficiency and side effects. The mean onset time of sensory block noted at T6 level was 4.25 min in group 1 and 2.5 min in group 2. Mean duration of pain relief in group 1 was 71.10 minutes while in group 2 it was 113.6 minutes and the difference between them is found to be highly significant. We conclude that the addition of 20 microgm fentanyl to hyperbaric lignocaine spinal anesthesia results in quicker onset of sensory and motor block without prolonging duration of motor block recovery.
