摘　　要：为探讨丙泊酚静脉麻醉与安氟醚吸入麻醉在巴马小型猪体外循环(CPB)中的麻醉效果,本研究选用巴马小型猪10头,平均分成2组,分别进行丙泊酚静脉麻醉和安氟醚吸入麻醉;开胸后进行全血肝素化处理,分别于升主动脉、上腔静脉和下腔静脉插管,连接体外循环机进行CPB;观察并记录麻醉诱导前(T0)、麻醉诱导后(T1)、CPB前即刻(T2)、降温至30℃(T3)、阻断主动脉前即刻(T4)、阻断主动脉后4min(T5)、开始复温即刻(T6)、停CPB即刻(T7)、关胸后即刻(T8)及手术结束拔管后10min(T9)10个时间点各组试验猪的生命体征、鼻温(NT)、心率(HR)、平均动脉压(MAP)、pH及血氧饱和度(SPO2)指标。结果2组试验猪于CPB实施前后的基本情况如体重、手术时间和麻醉时间等指标均无显著性差异(P>0.05);安氟醚组恢复自主呼吸的时间显著短于丙泊酚组(P<0.05);与T0和T1相比,各组试验猪在CPB进行时其NT、HR和MAP值均显著降低(P<0.05);但各组间及组内SPO2和pH差异不显著(P>0.05)。由此可见,丙泊酚静脉麻醉与安氟醚吸入麻醉均可用于巴马小型猪CPB中的麻醉。选用丙泊酚时,应根据手术过程中试验动物的反应情况适当调整用量;而安氟醚麻醉过程相对平稳,麻醉效果好,术后苏醒快,适合情况复杂且时间较长的手术。The assay was aimed to compare of propofol intravenous anesthesia and enflurane inhalation anesthesia in cardiopulmonary bypass of Bama Minipigs. 10 Bama Minipigs, the average into two groups were propofol intravenous anesthesia and enflurane inhalation anesthesia, and in preoperative, operative and postoperative the anesthesia monitoring. After openning breast, whole blood were treated with heparin, then the ascending aorta, superior vena cava and inferior vena cava were intubated respectively, and connected to a cardiopulmonary bypass machine line the CPB. The vital signs, nose temperature （NT） , heart rate （HR）, mean arterial pressure （MAP）, pH and blood oxygen saturation（SPO2） of each experimental pigs were observe and recorded within before introdution of anesthesia （T0）, after induction of anesthesia （T1）, immediately before CPB （T2）, cooling to 30 ℃ （T3）, blocking the aorta former immediate （T4）, blocking the aorta 4 min （T5）, start thawing immediate （T6）, stop CPB immediate （T7）, closed chest immediately after （T8） and drawing tube operation over 10 min （T9）. Two groups of weight number of pigs, operation time and anesthesia time all had no significant difference （P〉0.05）. Different fluorine ether group restore spontaneous breathing a short time in propofol group （P〈0.05）. Compared with the basic value（T0 and T1）, the NT, HR and MAP value of the experiment pigs were significantly lower （P〈0.05）. But each rooms and in the group SPO2 value and pH were not significant different （P〉0.05）. Propofol intravenous anesthesia during the operation should be based on the experimental animals of the reaction conditions appropriate adjustments propofol pump into the concentration; and different fluorine ether inhaled anesthesia during the procedure of smooth, anaeesthetic effect was good, postoperative came quickly, suitable for complicated cases, and the time was long operation.
