The aim of the study was to evaluate the effect of morphine administered with the TAP block on postoperative opioid consumption and pain scores and, secondarily, to determine whether the effect was systemic or local.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Methods:<\/jats:bold>\n                    This prospective, double\u2010blind, randomized controlled trial included 52 patients. In the IM group, morphine at a dose of 0.1\u2009mg\/kg based on ideal body weight (IBW) was administered IM. In addition, a bilateral TAP block was performed under ultrasound guidance using a total of 40\u2009mL of 0.25% bupivacaine, with 20\u2009mL injected on each side. In the TAP group, an ultrasound\u2010guided TAP block, including a total of 40\u2009mL of 0.25% bupivacaine and 0.1\u2009mg\/kg morphine according to the IBW of patients, was administered bilaterally.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:bold>Results:<\/jats:bold>\n                    Total morphine consumption 24\u2009h was 19.08\u2009+\u200911.35 in the IM group and 11.81\u2009+\u20097.02 in the TAP group, with an estimated difference in means of 7.2 (95% CI: 2.0, 12.5;\n                    <jats:italic>p<\/jats:italic>\n                    = 0.008). The morphine consumption after 6, 12, and 24\u2009h was lower in the TAP group than in the IM group (\n                    <jats:italic>p<\/jats:italic>\n                    = 0.033,\n                    <jats:italic>p<\/jats:italic>\n                    = 0.003, and\n                    <jats:italic>p<\/jats:italic>\n                    = 0.008, respectively).
