Abstract

Introduction: The use of Intrathecal morphine is very effective as post-cesarean section analgesia. However, the optimal dose is not determined yet. The objective of this study was to evaluate the efficacy of intrathecal bupivacaine 10 mg + 150 µg of morphine vs intrathecal bupivacaine 10 mg + 100 µg of morphine as an analgesic method in patients after caesarean section at the Vicente Corral Moscoso Hospital of the city of Cuenca – Ecuador in 2013.

Methods: A controlled blind clinical trial. 64 Patients who were treated with bupivacaine 10 mg + 150 µg of morphine and 64 who received bupivacaine 10 mg + 100 µg of morphine were studied. The quality of analgesia, efficacy and side effects of the two techniques were also studied.

Results: The dose of 150 µg morphine + 10 mg of bupivacaine was more effective than the 100 µg + 10 mg of bupivacaine in the evaluation of analgesia between 12 and 24 hours after the surgery. There were no differences in the hemodynamic behavior between the two groups.

Conclusions: The group that received the treatment based on bupivacaine 10mg + 150 µg of morphine had better results in the analgesic control after the surgery. Only one patient suffered vomiting as a secondary effect.
