Introduction: The paravertebral block (PVB) has been used with success, both as anaesthetic and analgesic techniques, for inguinal herniorrhaphy. PVB provides an analgesia equivalent to extensive peripheral nerve block for inguinal herniorrhaphy, offering an alternative method of postoperative pain management with fewer adverse events. PVB has been found to be more advantageous than conventional spinal anaesthesia for inguinal hernia repair, in terms of early ambulation and better postoperative pain scores. Materials and Methods: The study was an experimental double blinded randomized controlled study. After obtaining Institutional ethics committee’s approval 60 male patients of age group 18 to 65 years with ASA physical status 1 and 2 scheduled for elective unilateral hernia repair were selected for study. The patients were explained about the procedure and its complications, VAS scoring during the pre operative examination. Result: The two groups were statistically comparable with respect to age, weight, preoperative vital parameters, SBP, DBP, SPO2. Intra operatively incidence of hypotension and use of vasopressor was high in group S, 25 patients( 50%) as compared to no such incidence in group P. Total consumption of propofol was higher in group P compared to group S ( p < 0.001). The VAS score was highest at 6 hours for group P (p < 0.001) and 4 hours for group S(p<0.001) and was significant at 4, 6 hours. At 12, 24 hours there was no significant difference. The rescue analgesic Tramadol in boluses of 50mg IV was used if VAS score > 4 and repeated every 15 min until pain was relieved (VAS < 3). Conclusion: To conclude Paravertebral block can be used as an alternative to spinal anaesthesia in unilateral inguinal hernia repair.
