Abstract
Acute pain after surgery is an important clinical drawback occurs in patients
undergoing cesarean sections. Postoperative pain causes various complications,
including the risk of chronic pain. The Enhanced Recovery After Caesarean
Section (ERACS) protocol recommends intrathecal morphine and the
Transversus Abdominis Plane (TAP) block. This study aims to compare the
opioid requirement as an analgesic rescue between both techniques in patients
undergoing cesarean sections. This is an experimental study with a single-blind
randomized controlled trial design. Subjects were divided into two groups, each
consists of 22 patients. Patients were selected consecutively and grouped by
permuted block randomization. In the intratechal morphine group, the duration of
additional opioids was longer, with an average of 600.45 minutes (SD = 68.901),
than in the TAP block group, with an average of 438.18 minutes (SD = 46.867),
with a p-value of 0.001. The total dose of additional opioids in the intratechal
morphine group was smaller, with an average of 38.64 µg (SD = 14.775), than in
the TAP block group, with an average of 50.00 µg (SD = 18.898), with a p-value
of 0.043. In conclusion, intratechal morphine gives a better postoperative
analgesic effect than TAP block in patients undergoing cesarean sections
