Study of the factors that affect postoperative recovery

与不加芬太尼的七氟醚麻醉相比，七氟醚麻醉增加了患者术后恶心、呕吐的发生率，延迟了术后恢复。4)七氟醚麻醉诱导和维持七氟醚麻醉(VIMA)增加了日间病例宫腔镜术患者术后恶心、呕吐的发生率，延迟了术后恢复。5)与七氟醚麻醉相比，异丙酚麻醉下乳腺癌手术患者麻醉后心率变异性(HRV)高频段(HF)高，低频(LF)/HF低。6)腰麻诱导后HRV高频升高，随着疼痛和运动感觉的恢复，HRV高频恢复到麻醉前水平。7)采用双频指数(BIS)作为受控变量的模型预测控制器用于丙泊酚输注的自动闭环控制系统，减少了用药量，并更准确地将BIS值维持在目标设定点附近异氟醚和氟烷对培养的大鼠气管上皮细胞纤毛运动有强烈的抑制作用，而七氟烷对其有保护作用。戊巴比妥钠对其有明显的抑制作用，而高剂量的氯胺酮则使其增强。咪达唑仑和右美托咪定对其无影响。

1)There was a significant positive correlation between the duration of anesthesia and time to meet the discharge criteria in ambulatory anesthesia patients.2)Preanesthesia hydration shortened the time to meet the discharge criteria in patients undergoing ambulatory surgical patients anesthetized with inhaled sevoflurane.3)Sevoflurane anesthesia with supplemental fentanyl increased the incidence of postoperative nausea and vomiting and delayed the postoperative recovery in patients undergoing ambulatory breast cancer surgery, in comparison with sevofururane anesthesia without fentanyl.4)Volatile induction and maintenance of anesthesia (VIMA) with sevoflurane and nitrous oxide increased the incidence of postoperative nausea in patients undergoing day-case hysteroscopy, in comparison with VIMA with sevoflurane only.5) The high frequency band (HF) of heart rate variability (HRV) was high and the ratio of low frequency band (LF)/HF was low in postanesthesia patients undergoing ambulatory breast cancer surgery under propofol anesthesia, in comparison with sevoflurane anesthesia.6)HF of HRV increased after induction of spinal anesthesia and returned to preanesthesia level with the recovery of pain and motor sensations.7)The automated closed-loop control system for propofol infusion using a model predictive controller, which uses bispectral index (BIS) value as a controlled variable, decreased the drug consumption and maintain the BIS value more precisely around the target set point, in comparison with manual control by anesthesiologists.8)Isoflurane and halothane depressed cilirary motility strongly, but seveflurane preserved it in cultured rat tracheal epithelial cells. Pentbarbilal inhibited it potently and high dose of ketamine augmented it. Midazolam and dexmedetomidine did not affect it.
