ABSTRACT

Introduction: the concentration and speed in the administration of intrathecal multimodal anesthesia with fentanyl in cesareans section improve anesthetic efficacy while maintaining good hemodynamic control. Objective: to evaluate if some changes in intrathecal multimodal anesthesia improve its efficacy and safety in cesareans section. Material and methods: clinical trial, controlled, randomized, double blind; in pregnant women scheduled for cesarean section, divided into 3 groups: group F6B2: fentanyl 65 μg + hyperbaric bupivacaine 2.5 mg+ morphine 100 μg+ dexmedetomidine 5 μg; group F6B3: fentanyl 60 μg + hyperbaric bupivacaine 3 mg + morphine 100 μg + dexmedetomidine 5 μg; and group F7B2: fentanyl 70 μg + hyperbaric bupivacaine 2 mg + morphine 100 μg + dexmedetomidine 5 μg. The anesthetic efficacy was evaluated prior to the incision, during the dissection of the abdominal wall, upon the admission to the abdominal cavity, in the review of paracolic slides and in the immediate postoperative period, as well as the vital signs. Results: the F6B2 and F6B3 groups turned out to have greater anesthetic efficacy in the revision of paracolic slides (p = 0.02) and the F7B2 group had the highest safety with better hemodynamic control at 1 and 10 minutes (p = 0.03 and p = 0.03, respectively). Conclusions: changes in the administration of intrathecal multimodal anesthesia with fentanyl improved anesthetic efficacy, but decreased safety over hemodynamyc control.
