Summary We recruited 144 women of whom 131 underwent scheduled caesarean section and were allocated to intrathecal bupivacaine without (46) or with (47) morphine and postoperative rectus sheath bupivacaine; or intrathecal bupivacaine with morphine and postoperative rectus sheath saline (38). We measured postoperative pain with a 10‐point numeric rating scale. The mean ( SD ) areas under the curve for pain on movement during 48 postoperative hours were 273.5 (63.6), 223.8 (80.7) and 223.8 (80.7), respectively, p = 0.008. There was no difference between women who had intrathecal morphine with or without rectus sheath bupivacaine, p = 1. The equivalent values for pain at rest were 160.8 (64.7), 85.8 (79.4) and 82.8 (74.3), respectively, p < 0.001. There was no difference between women who had intrathecal morphine with or without rectus sheath bupivacaine, p = 0.98.
