We evaluated the usefulness of the intubating laryngeal mask airway (ILMA) in patients who were predicted to have possible difficult airway. Patients with possible difficult airway were defined as those with limited head extension, Mallampati's classification of grade IV, thyro-mental distance < 4 cm, or Cormack grade III-IV on the laryngoscopy. The control group was consisted of the patients without these conditions or impaired mouth opening. Insertion of the ILMA was successfully performed in all patients of both groups. In the group of possible difficult airway, 83% of patients were intubated through the ILMA successfully, and in the control group, 86%. We conclude that the ILMA may become an additional tool in patients with difficult intubation.
我们评估了插管喉罩气道（ILMA）在预计可能存在困难气道的患者中的实用性。预计可能存在困难气道的患者定义为头部伸展受限、Mallampati分级为IV级、甲状软骨-颏下距离<4cm或喉镜检查Cormack分级为III-IV级的患者。对照组由没有这些情况或张口受限的患者组成。两组所有患者均成功插入ILMA。在可能存在困难气道的组中，83%的患者通过ILMA成功插管，在对照组中这一比例为86%。我们得出结论，ILMA可能成为困难插管患者的一种辅助工具。
