【摘要】 目的 :观察异丙酚 -安氟醚复合控制性降压麻醉下实施口腔颌面部手术的效果。方法 :30例病人在吸入1.0 %～ 2 .0 %安氟醚的基础上 ,同时静注异丙酚 10～ 15mg/kg/h ,当手术需要降压时 ,增快异丙酚输入速率至 30～40mg/kg/h ,监测降压情况及停药后血压恢复情况。结果 :加快输入异丙酚后 (3.5± 0 .5 )min ,MAP降至 8.9～9.5kPa ;减慢异丙酚输入速率至 6～ 10mg/kg/h ,血压可维持在这一范围 ;停用异丙酚后 (5 .0± 0 .5 )min ,MAP自动恢复 ,降压期间HR、CVP、SpO2 和ECG均无明显异常。结论 :异丙酚 -安氟醚复合控制性降压效果确切、迅速 ,使用安全 ,易于调节。更多还原

【Abstract】 Objective:To observe the effects of induced hypotension with enflurane and propofol for oral and maxillofacial surgery.Methods:Thirty patients were anesthetized with enflurane inhalation(1.0～2.0) combined with propofol infusion(10～15 mg/kg/h).When controlled hypotension was required the rate of propofol was increased to 30-40mg/kg/h.The degree of hrpotension as well as the recovery of blood pressure were monitored.Results:(3.5±0.5)min after increasing the rate of propofol infusion the mean arterial pressure (MAP) descended to 8.9～9.5kPa,when decreaing the rate of propofol to 6～10mg/kg/h MAP was maintained within this range,and (5.5±0.5)min after withdrawal of propofol administration MAP recovered. No rebounding response was observed.During controlled hypotension HR,CVP,SpO 2 and ECG showed no significant chang.Conclusions:Combination of enflurane and propofol for controlled hypotension is an effective method which is rapid and easy to control.更多还原
