经喉罩全凭七氟醚吸入全麻在小儿手术中的应用

目的探讨在小儿麻醉中使用喉罩全凭七氟醚吸入麻醉的效果及安全性。方法选择60例2-10岁择期手术患儿，采用高浓度七氟醚诱导后，置入喉罩全凭吸入七氟醚全麻。结果60例患儿喉罩均成功置入，第1次置罩成功率86．7％，第2次置罩成功率93．3％．第3次置罩成功率100％。麻醉过程平稳，术中无呼吸道堵塞、咳嗽、喉痉挛及胃内容物误吸等。平均睁眼时间为（12.3±3．7）min，术后24h访视患儿对手术过程无记忆．无一例发生咽喉疼痛。结论在喉罩通气保证呼吸道畅通的条件下，全凭七氟醚吸入麻醉具有诱导平稳、起效迅速、清醒快而完全等优点，可安全有效的应用于小儿麻醉中。

The Application of Entirely Sevoflurane Inhalation Anesthesia by the Laryngeal Mask in Pediatric Surgery

Objective To explore the effect and safety of entirely sevoflurane inhalation anesthesia by the laryngeal mask in pediatric surgery. Method 60 cases of 2-10-year-old children were selected for surgery, placing laryngeal mask and depending only on inhaled sevoflurane anes thesia after the induction of high concentrations of sevoflurane. Result Laryngeal masks were successfully placed in 60 cases of children, the 1^st time with 86.7 % success rate, the 24 time with 93.3 % success rate, and the 3^rd time with 100 % success rate. The process of anesthesia was sta ble, without respiratory congestion, cough, throat spasm, aspiration of gastric contents and so on. The average time to open eyes was （12.3± 3.7） min, and children being visited 24 h later had no memory of surgical procedures, none of whom felt throat sore. Conclusion At the condition of laryngeal mask to keep smooth respiratory tract, sevoflurane inhalation anesthesia with an advantage of stable induction, rapid effect, fast and to tally awaking, can be used safely and effectively in pediatric anesthesia.
