Abstract
Aim: To compare recovery time and evaluate home readiness time after different dosage of hyperbaric bupivacaine.
Material and Methods: This study was performed in 3 different groups: group-I, group-II & group-III, each containing 50 patients. In study group-I, 6mg of hyperbaric bupivacaine, 8 mg in hyperbaric bupivacaine in group-II and in study group-III 10 mg hyperbaric bupivacaine was injected. The level of injection in all cases was at L2/3 vertebral interspace.
Results: In study group-I (6mg bupivacaine) failure rate was 6%. Perioperative complain of discomfort and pain was also high (12.76%). Study group-Ill (10mg bupivacaine) did not show any advantage over group-II (8 mg bupivacaine). The 10mg dose prolonged the stay in PACU and delayed home-readiness by 44 min when compared with the 8mg dose of spinal bupivacaine.
Conclusion: Standardized spinal anaesthesia technique with 8mg dose of hyperbaric bupivacaine produced a good quality highly predictable spinal block with average duration of 57 minutes stay in PACU and average home readiness time was 4.15 hours. Furthermore, a small change in dose on upper and lower side (6mg or 10 mg) altered the reliability, spread and recovery of the spinal anaesthesia.
