The ilioinguinal-iliohypogastric (IIIH) block is frequently used as multimodal analgesia for lower abdominal surgeries. The aim of this study is to compare the efficacy of IIIH block using ultrasound visualization for reducing postoperative pain after caesarean delivery (CD) in patients receiving intrathecal morphine (ITM) under spinal anesthesia. Participants were randomly assigned to 1 of 3 treatment groups for the bilateral IIIH block: Group A = 10 mL of 0.5% bupivacaine, Group B = 10 mL of 0.5% bupivacaine on one side and 10 mL of a normal saline (NSS) placebo block on the opposite side, and Group C = 10 mL of NSS placebo per side. Pain and nausea scores, treatment for pain and nausea, and patient satisfaction were recorded for 48 hours after CD. No differences were noted with respect to pain scores or treatment for pain over the 48 hours. There were no differences to the presence of nausea ( ), treatment for nausea ( ), pruritus ( ), emesis ( ), or patient satisfaction ( ). There were no differences in pain and nausea scores over the measured time periods (MANOVA, ). In parturients receiving ITM for elective CD, IIIH block offers no additional postoperative benefit for up to 48 hours.
