Foundation: The Postoperative pain is considered time-limited pain, often poorly controlled. Its management requires a great challenge, since postoperative analgesia must provide the mother with adequate control and at the same time facilitate care for the baby.
Objective: To evaluate the effectiveness of postoperative analgesia with the use of intrathecal morphine.
Method: Observational, descriptive and cross-sectional study carried out at the Martín Chang Puga General Teaching Hospital in the Nuevitas municipality, province of Camagüey, between January 2021 and December 2022. The sample was made up of 36 patients to whom subarachnoid anesthesia was applied with Hyperbaric lidocaine plus morphine for cesarean section.
Results: The age between 27-31 years predominated, 63.9% of those who underwent cesarean section did not report postoperative pain. Almost half of the sample (47.2%) studied presented side effects with the use of intrathecal morphine, with pruritus predominating. 80.5% of patients were satisfied with postoperative analgesia.
Conclusion: The majority of patients found satisfaction with the analgesic treatment despite the presence of adverse effects, so it can be stated that the use of intrathecal morphine is effective in the management of post-cesarean pain.
