Abstract: Background & Aims: Ilioinguinal (IIN) and iliohypogastric nerve (IHN) blocks with landmark techniques have higher failure rates and need large drug volumes. The use of peripheral nerve stimulator may help in increasing the accuracy, require fewer amounts of drug volumes and hence less chances of drug toxicity .In this study, we compared the duration of post operative analgesia and total number of analgesics consumed within 24 hours between peripheral nerve stimulator guided nerve block & institutional protocol of administering analgesics. Material and methods: Fifty two male patients, aged 18-70years belonging to American Society of Anesthesiology grade I and II, posted for openinguinal hernia repair were enrolled in this prospective randomized, control trial and divided randomly into 2 groups of 26 each by sealed envelope method . Group B received peripheral nerve stimulator guided IIN and IHN block using injection ropivacaine 0.25% 20ml with 4mg injection dexamethasone & Group D received Inj diclofenac sodium 75mg in 100ml normal saline after wound closure. Paired and unpaired t tests were used for comparison between two groups. Chi square test was used for qualitative analysis and Mann Whitney test was used for assessing visual analogue scale. Results: The mean duration of post operative analgesia was 476.30 +24.4minutes in group B whereas it was 296.3+ 16.7 minutes in group D( p value of 0.000) . There was statistically highly significant difference (p = 0.000) between total analgesics consumption between the two groups. Conclusion: Peripheral nerve stimulator guided IIN and IIH blocks are an effective technique for providing good postoperative analgesia in inguinal hernia surgeries.
