So sánh tác dụng dự phòng tụt huyết áp của dung dịch voluven 6% với Ringer lactat khi gây tê tủy sống để mổ lấy thai

Abstract

Objective: To compare the hypotension prophylactic of voluven 6% solution (7ml/kg) versus Ringer's lactate (15ml/kg) at the beginning of spinal anesthesia for caesarean section. Subject and method: A randomized clinical trial comparing 100 women with spinal anesthesia for cesarean section divided into 2 groups: HES group, intravenous 6% voluven, 7ml/kg; group RL, intravenously at 15 ml/kg at the time of initiation of anesthesia for spinal anesthesia. Result: The hypotension rate of HES group and RL group was 16% and 46%, respectively. The recurrence hypotension rate was 0% (HES group) and 22% (group RL). The rate of ephedrine use was 12% (HES group) and 40% (group RL). Conclusion: The infusion method at the beginning of spinal anesthesia for caesarean section with voluven 6% (7 ml/kg) was better prophylaxis of hypotension than intravenous infusion of lactate ringer (15 mg/ml).
