Abstract :

Background– Spinal anaesthesia 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. But some reports of neurotoxicity produce doubts on the use of lignocaine for spinal anaesthesia. But some suggest that lignocaine concentration might be responsible for these complications. In view of the controversy and uncertainty surrounding the use of spinal lignocaine, the present study was undertaken to re–evaluation of the safety and analgesic efficacy of spinal hyperbaric lignocaine 2% regarding the occurrence of transient neurological symptoms and evaluation of any beneficial and adverse effects of addition of fentanyl as an adjuvant in spinal anaesthesia in patients undergoing elective caesarean section. Method– 50 patients scheduled for elective caesarean section were divided into two groups (25 patients in each group). Group A received 40mg Lignocaine plus 0.5ml normal saline and group B received Lignocaine 40mg and fentanyl (20g) intrathecally (total volume 2.5 ml in both). Onset and duration of sensory and motor blockade and Duration of analgesia and any side effects were recorded. Results – The onset and time to reach the highest level of sensory block was significantly less in group B. Time of regression of sensory block to T10 level was significantly prolonged in group B as compared to group A. Onset and duration of motor block was similar in both the groups. Incidence of side effects was not significant in both the groups.
