Abstract
Objective: The efficacy and adverse effects of 0.5 percent ropivacaine and 0.5 percent bupivacaine were evaluated for single-shot epidural anaesthesia in patients undergoing inguinal hernia repair surgery.
Methodology: We conducted our research using a randomised, double-blind, placebo-controlled methodology. It lasted for six months, from July 2021 to December 2021 at Khyber teaching Hospital . The study involved 60 hernia repair surgery patients with an ASA physical status of I and II. Thirty patients were divided into two groups and given 0.5 percent ropivacaine (0.5%) or (0.5%) bupivacaine (0.5%). The initiation, maximum, and median heights of sensory block, as well as the time passed before two segment recession occurred, were all measured. Motor obstruction was determined using a modified Bromage scale. All of the most common side effects, as well as the block's overall length and duration, were noted.
Results: Both patient groups were comparable in terms of age, height, weight, gender, and ASA status. There was no significant difference in the time required for the sensory block to commence and reach its maximum height. The maximum level of sensory block was T6 (T5-T8) in those who received ropivacaine, while the highest level was T5 in those who received bupivacaine (T4-T7). Both groups received the same amount of time for the durations of two-segment regression and sensory block. The bupivacaine group had a considerably longer overall duration of motor block (159.01 minutes vs 134.22 minutes, p <0.001). Additionally, the modified Bromage scale was considerably higher in the group receiving bupivacaine (2.84 vs 1.94 min, p0.001). Both groups experienced adverse symptoms such as hypotension, bradycardia, nausea, vomiting, and shivering.
Conclusion: Epidural anaesthesia with 0.5 percent ropivacaine was both safe and effective. Early patient mobilisation following inguinal hernia repair surgery may be beneficial, since motor blockade was reduced when 0.5 percent bupivacaine was used.
