Abstract
Purpose: To evaluate the effectiveness of remimazolam in preventing adverse reactions triggered by carboprost tromethamine during cesarean section procedures.
Methods: A total of 200 parturients scheduled for cesarean sections at risk of postpartum hemorrhage in our hospital from October 2022 to July 2023 were included. The participants were assigned via random number table method to either a study group or a control group, resulting in 100 cases in each. All parturients received combined spinal and epidural anesthesia (CSEA) during cesarean section, followed by administration of carboprost tromethamine (250 µg) for preventing postpartum hemorrhage after childbirth. CSEA was performed with 1.8 to 2 mL of 0.5% bupivacaine and 7 to 10 mL of 2% lidocaine. The study group was given remimazolam via intravenous infusion at a rate of 0.3 mg/kg/h commencing at 1 minute prior to CSEA and concluding with a final dosage adjustment 20 minutes preceding the end of surgery, while the control group was given the same volume of saline within this time frame. Primary outcome measures were adverse reactions and sedative effects of the parturients.
Findings: Nausea and vomiting were the only adverse reactions that exhibited significant differences between groups. The study group reported significantly fewer cases (32 cases) of nausea and vomiting when compared to the 48 cases observed in the control group. Moreover, the use of remimazolam appeared to alleviate the severity of nausea and vomiting, as evidenced by the significantly lower incidence of Grade III event and the higher risk of Grade I event in comparison with the control group (P < 0.05). The Apgar scores of newborns at birth and 5 minutes after birth were compared, and no statistically significant difference was found (P > 0.05). Parturients receiving remimazolam exhibited better effective sedation outcomes and were more satisfied with the treatment when compared with controls (P < 0.05). There were no significant differences in postpartum bleeding volume at 2 and 12 hours postpartum, as well as in the duration of postpartum bleeding between the two groups (P > 0.05).
Implications: Intravenous administration of remimazolam effectively prevents adverse reactions induced by carboprost tromethamine during cesarean section performed under CSEA, thereby improving sedative effects.
