In pediatric practice, complications due to the laryngeal mask airway (LMA) have been studied with size 2 LMA, but not with size 1 LMA. We, therefore, compared prospectively the complications induced by LMA size 1 and 2 in 141 children aged 21 days to 11 yr. Intraoperative and lowest SpO2 values after removal of LMA were recorded. The following complications were recorded: cough, laryngospasm, bronchospasm, apnea, and airway obstruction. In 14 patients in the size 1 LMA group and 26 patients in the size 2 LMA group, pharyngolaryngeal structures were checked with fiberoptic examination. The number of attempts, complications, intraoperative SpO2, and lowest SpO2 values were similar when using size 1 and size 2 LMA. Fiberoptic examination of size 1 LMA showed a high incidence of impinging of the epiglottis in the LMA bars without airway obstruction. In conclusion, there was no difference in the complication rate between the two pediatric sizes of LMA when used in pediatric patients.
在儿科临床实践中，已对2号喉罩气道（LMA）的并发症进行了研究，但未对1号LMA进行研究。因此，我们前瞻性地比较了141名年龄在21天至11岁的儿童使用1号和2号LMA引起的并发症。记录了移除LMA后的术中及最低SpO2值。记录了以下并发症：咳嗽、喉痉挛、支气管痉挛、呼吸暂停和气道梗阻。对1号LMA组的14名患者和2号LMA组的26名患者进行了纤维喉镜检查。使用1号和2号LMA时，尝试次数、并发症、术中SpO2和最低SpO2值相似。1号LMA的纤维喉镜检查显示，会厌撞击LMA杆的发生率较高，但无气道梗阻。总之，两种儿科尺寸的LMA在儿科患者中使用时并发症发生率无差异。
