We experienced two cases of difficult airway management using laryngeal mask airway (LMA) in children. LMA Classic (LMA-C) was used for a 4-year-old female patient and SOFTSEAL LMA (LMA-S) was used for a 15-year-old female patient. Both patients were successfully intubated by fiberoptic tracheal intubation through LMA. We compare these two kinds of LMA in fiberoptic intubation method. Because the diameter of the shaft is wider than LMA-C, LMA-S could pass through much larger size endotracheal tube (ETT). 4.0 mm ETT could pass through LMA #1 and #1.5 in both LMAs. 5.0 mm ETT could pass through LMA-S #2, but only 4.5 mm ETT could pass through LMA-C #2. In #2.5, LMA-S and LMA-C could be passed by 6.0 mm ETT and 5.5 mm ETT respectively. Also LMA-S and LMA-C #3 could be passed by 7.0 mm ETT and 6.5 mm ETT respectively. We conclude that SOFTSEAL LMA is more useful than LMA Classic for fiberoptic tracheal intubation technique.
我们遇到了两例在儿童中使用喉罩气道（LMA）进行困难气道管理的病例。一名4岁女性患者使用了经典喉罩（LMA-C），一名15岁女性患者使用了柔软密封喉罩（LMA-S）。两名患者均通过经LMA的纤维光导气管插管成功插管。我们比较了这两种LMA在纤维光导插管方法中的应用。由于LMA-S的管身直径比LMA-C宽，LMA-S能够通过尺寸大得多的气管内导管（ETT）。4.0毫米的ETT在两种LMA中都能通过1号和1.5号LMA。5.0毫米的ETT能通过2号LMA-S，但只有4.5毫米的ETT能通过2号LMA-C。在2.5号中，6.0毫米的ETT和5.5毫米的ETT分别能通过LMA-S和LMA-C。同样，7.0毫米的ETT和6.5毫米的ETT分别能通过LMA-S和LMA-C的3号。我们得出结论，对于纤维光导气管插管技术，柔软密封喉罩比经典喉罩更有用。
