地氟醚为强效吸入麻醉药,血-气溶解度与N_2O相仿,是小儿门诊手术较理想的麻醉药。但地氟醚有刺激气味,吸入浓度稍大易引起呛咳、喉痉挛、呼吸暂停和缺氧等。选择45例在门诊作疝修补、睾丸固定、包皮环切术的小儿。术前均经鼻滴咪唑安定0.2～0.3mg·kg~(-1)。先用面罩吸氟烷-N_2O(60％)-O_2(40％)诱导,意识消失后在持续吸1.0MAC氟烷下行骶管神经阻滞
Desflurane is a potent inhalation anesthetic, blood-gas solubility similar to N2O, pediatric outpatient surgery is an ideal anesthetic. However, desflurane has a stimulating odor, slightly higher inhaled concentration can cause cough, laryngospasm, apnea and hypoxia. Select 45 cases in the outpatient hernia repair, testicular fixation, circumcision of children. Preoperative nasal drops of midazolam 0.2 ~ 0.3mg · kg ~ (-1). The first use of mask inhalation of halothane - N_2O (60%) - O_2 (40%) induced by the disappearance of consciousness continued to suck 1.0MAC halothane downstream caudal nerve block
