Cesarean Section Complications
Conditions
Brief summary
Comparing two treatments for shivering after cesarean delivery for labor dystocia under epidural anesthesia.
Detailed description
It is a double blinded randomized control trial. Study population: parturients undergoing a cesarean delivery for labor dystocia under epidural anesthesia experiencing shivering grade III or IV on the standardized shivering scale of Crossley and Mahajan Experimental group: dexmedetomidine 0.35 mcg/kg IV in 2 minutes Control group: meperidine 0.35 mg/kg IV in 2 minutes Primary outcome : Time to stop level III and IV shivering on the Crossley and Mahajan standardized shivering scale after the administration of the study drug Secondary outcome: Response rate, incidence of nausea, vomiting, hypotension, bradycardia, maternal satisfaction and a cost-benefit analysis. The hypothesis is that dexmedetomidine will act faster, will have a superior response rate with less adverse effects.
Interventions
0.35 mcg/kg intravenous in 2 minutes if shivering 5 minutes after delivery
0.35 mg/kg intravenous in 2 minutes if shivering 5 minutes after delivery

Study design
Masking description
Double-blinded randomized study: meperidine and dexmedetomidine will be prepared at the hospital pharmacy in a 10 mL seringue with equivalent dilution in order to gave mL/kg.
Intervention model description
Comparing two groups: experimental (dexmedetomidine) versus control (meperidine)
