Objectives: To evaluate the effectiveness of lidocaine injection in mesosalpinx for pain relief during, immediately after and one hour post-operative for post-partum tubal sterilization in Srinagarind Hospital.Materials and Methods: 139 post-partum women participated, but 79 women were excluded. The remaining 60 women were recruited in this randomized, double-blinded, placebo controlled study. They undergoing postpartum tubal sterilization under local anesthesia performed by residents at the Department of Obstetrics and Gynecology. They were randomly assigned to one of two groups. They all received 4 ml solution injection in mesosalpinx divided for each side. Group one received 1% lidocaine 4 ml (40mg). And the other group received 0.9%NSS 4 ml. The intra-operative, immediately after and one hour post-operative pain was measured by using a numerical rating score (NRS) from 0 to 10.Result: There was no significant difference in the mean of intra-operative, immediately after and one hour post-operative NRS between the lidocaine group and placebo group (mean difference -0.7, 95%CI, -1.65 to 0.25 (p-value 0.147))Conclusion: Mesosalpinx injection of lidocaine was not effective for pain relief during and after post-partum tubal sterilization under local anesthesia.
