We compared intubating conditions under sevoflurane (group S) and halothane (group H) anesthesia in pediatric patients for otorhinolaryngological surgery. One hundred and six patients were divided randomly into group S (n = 60) and group H (n = 46). Anesthesia was induced with nitrous oxide-oxygen-sevoflurane (GOS, end-tidal sevoflurane concentration; 4.5%) or nitrous oxide-oxygen-halothane (GOF, end-tidal halothane concentration; 1.6%). Intubating conditions were assessed according to the intubation score, which consists of the following three factors; mouth opening, visibility of vocal cord and body movement. Each factor is divided into three grades (0, 1, 2); total scores of 0 correspond to excellent. In comparing the groups with respect to anesthetic induction, group S required 180 sec for disappearance of spontaneous breathing and 660 sec for completion of intubation, while, in group H, the above time intervals were 188 and 676 sec, respectively. We achieved significantly better intubating conditions in group H than group S. There were significantly more cases in group S than in group H in which vocal cord visibility was insufficient. Body movement during intubation was observed in 27% and 26% of patients in group S and H, respectively. In conclusion, halothane anesthesia provides better intubating conditions than sevoflurane anesthesia in slow induction for pediatric patients.
我们比较了七氟醚（S组）和氟烷（H组）麻醉下小儿耳鼻喉科手术患者的插管条件。106例患者随机分为S组（n = 60）和H组（n = 46）。分别采用氧化亚氮-氧气-七氟醚（GOS，呼气末七氟醚浓度4.5%）或氧化亚氮-氧气-氟烷（GOF，呼气末氟烷浓度1.6%）诱导麻醉。根据插管评分评估插管条件，该评分由以下三个因素组成：张口度、声带可视度和身体活动。每个因素分为三个等级（0、1、2）；总分0分对应优秀。在比较两组的麻醉诱导情况时，S组自主呼吸消失需180秒，插管完成需660秒，而H组上述时间间隔分别为188秒和676秒。我们发现H组的插管条件明显优于S组。S组声带可视度不足的病例明显多于H组。S组和H组分别有27%和26%的患者在插管过程中出现身体活动。总之，对于小儿患者的慢诱导麻醉，氟烷麻醉比七氟醚麻醉提供更好的插管条件。
