What Researchers Did
Researchers conducted a double-blind randomised prospective study involving 34 patients undergoing elective repeat cesarean section to evaluate the effects of adding intrathecal morphine to spinal bupivacaine.
What They Found
Intrathecal morphine significantly improved analgesia, with 82% of patients receiving morphine not needing intraoperative supplementation compared to 41% in the control group. Postoperatively, morphine recipients requested additional analgesia after 27 hours, significantly longer than the 2 hours for control patients, with no adverse effects on neonatal condition.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada, nor did it involve Canadian researchers or participants.
Study Limitations
The study's small sample size of 34 patients and focus on elective repeat cesarean sections limit the generalizability of its findings.
