The frequency and pattern of laryngeal mask airway (LMA) usage in a regional general hospital has been studied. Data were collected prospectively by means of a standardized record sheet which was completed at the time of anesthetic administration. During a 19-month period 10,150 patients underwent surgical procedures requiring general or regional anesthesia, of which 1,096 (men/ women: 791/305, ASA 3 or 4: 350, mean age: 64 years) were managed with the LMA. A clinically pattern airway was provided in 99.75% of occasions of whom 44.4% breathed spontaneously and 55.3% underwent positive pressure ventilation. The monthly frequencies of LMA usage increased significantly during the second year of the survey (25.1% vs 12.8%). Problems were recorded in 16.3% of cases: air leak 8.0%, laryngospasm 1.8%, desaturation (SpO2 < or = 90%) 1.8%, severe hypercarbia (PETCO2 > or = 50 mmHg) 1.0%, regurgitation 0.09%, sore throat 3.4%. No patient required intensive care management postoperatively. There were five cases of failed intubation managed with the LMA. This survey has shown that LMA has a well established role in anesthetic practice. Use of this device is equally safe and effective for both controlled and spontaneous ventilation in a wide range of starve patients undergoing most types of surgery.
一家地区综合医院喉罩气道（LMA）的使用频率和模式已得到研究。通过在麻醉给药时填写的标准化记录表前瞻性收集数据。在19个月期间，10150例患者接受了需要全身或区域麻醉的外科手术，其中1096例（男/女：791/305，美国麻醉医师协会[ASA]分级3或4级：350例，平均年龄：64岁）使用了LMA。在99.75%的情况下提供了临床模式气道，其中44.4%自主呼吸，55.3%接受正压通气。调查第二年LMA的月使用频率显著增加（25.1%对12.8%）。16.3%的病例记录有问题：漏气8.0%，喉痉挛1.8%，血氧饱和度下降（SpO2≤90%）1.8%，严重高碳酸血症（呼气末二氧化碳分压[PETCO2]≥50 mmHg）1.0%，反流0.09%，咽痛3.4%。术后无患者需要重症监护管理。有5例插管失败用LMA处理。这项调查表明LMA在麻醉实践中有既定的作用。对于大多数类型手术的广泛饥饿患者，该设备用于控制通气和自主通气同样安全有效。
