Forty-eight children, aged between 2 and 10 years, admitted as day cases for otological surgery were allocated at random into two groups. The first group was anaesthetised using a standard facemask, and the second with a laryngeal mask airway. The laryngeal airway produced a satisfactory airway in all children, and was inserted on the first attempt in 67% of patients. Hypoxia was significantly less frequent in the laryngeal airway group (p less than 0.05), and there were significantly fewer interruptions to surgery than in the facemask group (p less than 0.001). Patient safety, operating and anaesthetic conditions were all considered superior in the laryngeal airway group.
48名年龄在2至10岁之间的儿童作为日间手术患者接受耳科手术，被随机分为两组。第一组使用标准面罩进行麻醉，第二组使用喉罩气道进行麻醉。喉罩气道在所有儿童中均产生了满意的气道，67%的患者首次尝试就成功插入。喉罩气道组的低氧血症发生率显著较低（p<0.05），手术中断次数也显著少于面罩组（p<0.001）。喉罩气道组在患者安全、手术和麻醉条件方面均被认为更优。
