ContextOptimization and providing excellent quality of postoperative analgesia after total abdominal hysterectomy is a determinant factor of better clinical outcome, increases patient satisfaction, and allows early mobilization of the patient.AimsThe aim of this study is to compare the postoperative analgesic efficacy of wound site infiltration (WSI) and ultrasound-guided transversus abdominis plane block (TAPB) with 0.5% ropivacaine in lower abdominal surgeries under spinal anesthesia.Settings And DesignThis was a randomized controlled study.Subjects And MethodsOne hundred and ten patients undergoing lower abdominal surgeries were randomly allocated to two groups (WSI and TAP) of 55 patients in each. At the end of the surgical procedure, 2.5 mg/kg of the drug ropivacaine 0.5% was administered by an anesthesiologist through either of the routes of study. Visual analog score (VAS) assessment was done at every 30 min, for 1½ h, every 2 for 24 h postoperatively. Injection diclofenac sodium 75 mg intramuscularly was given whenever VAS was >3 as rescue analgesic.Statistical Analysis UsedEpi Info 7.0 version software for Windows was used. All analyses were performed using Kolmogorov-Smirnov test. Mann-Whitney test was applied to detect the difference between the two groups. P < 0.05 was considered statistically significant.ResultsPostoperative VAS scores in Group TAP were significantly reduced at 30 min, 1st h, 1 h 30 min, 2, 4, 6, 8, 10, 12, 18, and 24 h (P < 0.001). The total doses of rescue analgesics administered were also low in the Group TAP (1.41 ± 0.538) with P < 0.0001 in comparison to Group WSI (2.24 ± 0.637) with P < 0.001.ConclusionsThe quality of analgesia along with lesser rescue analgesic requirement and their side effects makes the TAPB, a good and safer option for lower abdominal gynecological surgeries. Both WSI and USG TAPB are effective in providing postoperative analgesia as a part of multimodal analgesia in lower abdominal surgeries. However, in our study the quality of analgesia along with lesser rescue analgesic requirement and their side effects makes the TAPB, a good and safer option for lower abdominal gynecological surgeries.
