Background: Inguinal hernia repair is the commonest operation in surgical practice. Now it is also
performed under regional nerve blocks by blocking nerves ilioinguinal (II)/iliohypogastric (IH) and
genital branch of genital femoral nerve combined with a surgical feild inltration with a long-acting local anaesthetic(LA)
agent. LA inltration improves acute postoperative pain management, decreases postoperative visual analogue
scale(VAS)scores, opioid demand, and time to rst rescue analgesic administration. Thi Objective: s study was carried out to
compare the effect of ultrasound guided ilioinguinal/ iliohypogastric nerve and genital branch of genitofemoral nerve block
with conventional (blind) block in terms of success rate, postoperative analgesia and complications. Method: We conducted a
prospective randomized controlled studyamongst 100 ASA I-III patients posted electively for open inguinal hernia repair.
Various parameters such as age, sex, weight, BMI, vitals like pulse rate, ECG, blood pressure was recorded and Post-Operative
VAS at 30minutes, 1hr, 1hr30mins, 2hrs, 2hrs30mins, 3hrs, 3hrs30 minutes and 4hours was noted. Qualitative and quantitative
analysis was done. Result: In conventional group 8 (16%) patients amongst 50 (100%) required general anaesthesia in
between the surgery even after sedation + analgesia+ propofol whereas in USG group 2 (8%) patients required general
anaesthesia. The patient receiving USG guided block had signicantly lower post-operative VAS scores till 2 hours 30 mins as
compared to the patient receiving conventional ILN/INH nerve blocks who had higher VAS scores . There Conclusion : by we
found that ultrasound guided block for open inguinal hernia repair has signicantly better patient care in comparison with
conventional block.
