Introduction: Wound site Local Anesthesia Infiltration (LAI) and Transversus Abdominis Plane (TAP) block are techniques commonly used alone or in combination to improve postoperative analgesia. The primary outcome of this study is to compare the first analgesia request time between LAI group and TAP-block group.
Methods: This prospective cohort study recruits 60 patients who underwent elective lower abdominal surgery under general anesthesia with systemic random sampling. Those patients who received bilateral TAP-block (blind technique) with 20 ml of 0.25% bupivacaine considered as TAP-block group. The LAI group was those patients who receive wound site local anesthesia infiltration with 20 ml of 0.25% bupivacaine. Verbal Numeric Rate Scale (VNRS) score and other variables were documented starting from 30 min to 24th h after the end of surgery.
Results: The median and IQR for time to first analgesia request were significantly longer in TAP-block [673(620-765) min] compared to LAI group [227(195-235) min]. Tramadol consumption within 24 h postoperatively were 100 (100-100) mg in TAP-block compared to 175 (150-200) mg in LAI group (P-value<0.001). At 30 min and after one hour postoperatively statistically significant lower median pain VNRS score were recorded in LAI group compared to TAP-block. There were statistically significant differences at 4th, 6th and 12th h showing lower median pain VNRS score in the TAP-block group.
Conclusion: For immediate and early postoperative pain LAI group recorded lower pain VNRS but TAP-block group showed prolonged time to first analgesia request; less total analgesia consumption and extended pain relief for lower abdominal procedures done under general anesthesia.
