Effects of betamethasone administrated before surgery on shiver during surgery in cesarean section parturients under spinal anesthesia

Objective To research proper dosage of betamethasone administrated before surgery that can relieve shiver during surgery in cesarean section parturients.Methods 120 cases,ASAⅠ parturients undergoing cesarean section were randomly allocated to 4 groups(30 cases in each group),2 mg of dexamethasone,4 mg of dexamethasone,8 mg of dexamethasone and normal saline were intravenously injected respectively after anesthetic level fixed.Observed the change of parturients′ resperation and blood pressure continuously and shiver of parturients,recorded Apgar score of neonatus.Results There were no signicant differences in SpO2,BP and Apgar score among 4 groups.The rating and score of shiver of parturients in B2 group,B4 group and B8 group were significantly lower than those of C group.The rating and score of shiver of parturients in B4 group and B8 group were significant lower than those of B2 group.The rating and score of shiver of parturients had no significant difference between B4 group and B8 group.Conclusion Betamethesone no less than 4 mg administrated before surgery can effectively and safely prevent shiver of parturients undergoing cesarean section in surgery.
