口腔组织血流量可直接影响手术血液丧失量。不同麻醉方法对口腔组织血流量有不同影响。本文以免为实验动物,对照性地研究了不同麻醉技术对舌粘膜血流量的影响。 材料和方法 将实验兔随机分为4组:7只接受50％一氧化氮(N_2O)麻醉,6只接受1.0和1.5最小牙槽浓度异丙烷(ISO)麻醉,8只接受10,20和40μg/kg芬太尼(FENT)麻醉,7只接受100,200和400μg/kg/min propofol(PROP)麻醉,应用激光多普勒流量计测量麻醉前和麻醉后舌粘膜组织血流量(TMBF),同时测量心率(HR),收缩压(SBP),平均动脉压(MAP)和
Oral tissue blood flow can directly affect surgical blood loss. Different methods of anesthesia have different effects on oral tissue blood flow. In this paper, to avoid the experimental animals, comparative study of different anesthetic techniques on the tongue mucosal blood flow. MATERIALS AND METHODS The experimental rabbits were randomly divided into 4 groups: 7 were anesthetized with 50% nitrous oxide (N 2 O), 6 received 1.0 and 1.5 minimum isoflurane (ISO) anesthesia, 8 received 10, 20 and 40 μg / kg of FENT and seven of propofol (PROP) at 100, 200 and 400 μg / kg / min. TMBF was measured before and after anesthesia with a laser Doppler flowmeter. Simultaneous measurement Heart rate (HR), systolic blood pressure (SBP), mean arterial pressure (MAP) and
