Application of intravenous anesthesia in combination with oropharyngeal airway ventilation in hysteroscopy / 中国基层医药

ABSTRACT

Objective To observe the safety and efficiency of two different ways of intravenous anesthesia combined with oropharyngeal airway ventilation in hysteroscope operation.Methods 40 ASA Ⅰ ～ Ⅱ patients undergoing hysteroscopy were randomly assigned into two groups,20 cases in each group.Patients in the group A,B,were administered respectively with sufentanil 0.1 μg/kg or dexmedetomidine 0.5μg/kg by micro-pump in at least 10 minutes before operation.The perioperative hemodynamic index was recorded.The different outcomes including total dose of propofol,hemodynamic changes,recovery time,postoperative uterine contraction pain and episodes of adverse actions were observed and compared.Results Compared with group A,heart rate (HR) and systolic blood pressure (SBP) were higher in group B (P ＜ 0.05).The recovery time in group A was longer than that in group B (P ＜0.05).But there were no statistical differences of the total dosage of propofol,the incidence of respiratory depression,and the incidence rate of drowsiness after operation betwween group A and group B (P ＞ 0.05).Conclusion There was safe and effective of two different ways of intravenous anesthesia combined with oropharyngeal airway ventilation in hysteroscope operation,but the dynamic index was more stable,and the recovery time was shorter in patients with lowdose dexmedetomidine.
