喉罩与气管插管在不同环境院前急救中的应用效果

Application value of laryngeal mask airway and trachea cannula under different conditions of emergency medical service

将急救分站分为4组,A、C两组用喉罩,B、D两组用气管导管,在现场和车辆行进途中为心搏骤停患者建立高级气道.比较4组患者一次插管成功率、操作所需时间及复苏成功率.结果显示,A、C组在急救过程中一次插管成功率、复苏成功率高于B、D组,操作所需时间明显短于B、D组,两者比较差异有统计学意义（P＜0.05）.说明在院前急救时,运用喉罩通气较气管插管更快速有效,且操作方便、成功率高.

First-aid stations were divided randomly into 4 groups. Advanced airway for sudden cardiac arrest patients with laryngeal mask airway （LMA） was established in groups A and C while trachea cannula was inserted on spot of emergency medical service （ EMS ） or in ambulance in groups B and D. According to the results, the success rate of insertion and cardiopulmonary resuscitation （CPR） of groups A and C were higher than the other two groups （P 〈 0. 05）. However, the required time was shorter （ P 〈 0. 05）. Due to a difficult catheterization environment, LMA is more effective and convenient than trachea cannula in EMS.
