ABSTRACT
Objective:
Meperidine used to control shivering during perioperative period has associated side effects. The present study compared the safety of selective α2-adrenoreceptor agonist dexmedetomidine and meperidine for anti-shivering in primiparas after caesarean delivery under combined spinal-epidural anesthesia (CSEA).Methods:
100 primiparas scheduled for caesarean delivery were randomly allocated to dexmedetomidine group (Group D, n=50) and meperidine positive control group (Group M, n=50). Primiparas experienced shivering that continued to cord clamping were treated with dexmedetomidine (0.5 µg/kg) or meperidine (0.5 mg/kg) after cord clamping. The primary outcome measures were incidence of nausea, vomiting, and respiratory depression. Secondary outcome measures were shivering score, vital signs including blood pressure, heart rate and O2 saturation, tympanic temperature, and sedation score.Results:
Dexmedetomidine provided similar anti-shivering effects as meperidine in patients after caesarean delivery under CSEA, evidenced as all shivering primiparas responded to either dexmedetomidine or meperidine treatment within 15 min. However, incidence of nausea and vomiting were significantly lower after dexmedetomidine treatment, accompanied with more stable blood pressure. Dexmedetomidine also provided well regulation of tympanic temperature and good sedation.Conclusion:
Selective α2-adrenoreceptor agonist dexmedetomidine has a better safety profile compared with meperidine for anti-shivering in primiparas undergoing caesarean delivery. Dexmedetomidine could be a better choice for anti-shivering in patients requiring caesarean section. The mechanism of anti-shivering for dexmedetomidine may relate to well regulation of temperature and good sedation.Palavras-chave
