５０例人工流产患者随机分为两组。Ｉ组：静注异丙酚１ｍｇ／ｋｇ和氯胺酮０．２ｍｇ／ｋｇ：Ⅱ组：单次静注异丙酚２ｍｇ－２．５ｍｇ／ｋｇ，术中必要时可追加异丙酚２０－３０ｍｇ以维持适当的麻醉深度。术中观察两组血压、心率、氧饱和度（ＳｐＯ２）记录麻醉时间、苏醒时间及异丙酚的总量。结果表明：微量氯胺酮能增强异丙酚的麻醉作用，而并未加重其对循环、呼吸的抑制作用，且麻醉苏醒时间和质量不受影响。结论：单用异丙酚或与氯胺酮联合用于人工流产术均为安全、有效、可行的麻醉方式，但后者在使用中更具优势。
50 cases of induced abortion were randomly divided into two groups. Group I: intravenous propofol 1mg / kg and ketamine 0.2mg / kg: Group II: a single intravenous propofol 2mg-2.5mg / kg, if necessary, intraoperative additional propofol 20-30mg Maintain proper depth of anesthesia. Intraoperative blood pressure, heart rate, oxygen saturation (SpO2) were recorded in both groups to record anesthesia time, recovery time and the total amount of propofol. The results showed that trace ketamine can enhance the anesthetic effect of propofol, but did not aggravate its inhibitory effect on circulation and respiration, and the anesthesia recovery time and quality were not affected. CONCLUSIONS: Propofol alone or in combination with ketamine for abortion is a safe, effective and viable method of anesthesia, but the latter is more advantageous in use.
