气囊-面罩、食管气管导管和经口气管内插管在心肺复苏中的应用评价

【目的】探讨气囊-面罩、食管．气管导管盲插法和经口气管插管法在心肺复苏中（CPR）的应用价值。【方法】351例心脏呼吸骤停患者按照有无咽部解剖生理异常，分为正常组和异常组。每组根据CPR时对患者建立人工气道的不同措施将其随机均分为3组，A组常规CPR时即使用气囊-面罩通气；B组常规CPR时即行食管-气管导管盲插法；C组常规CPR时即行气管导管经口插管法。比较3种方法建立人工通气所需时间，复苏过程中患者的血氧饱和度以及复苏成功率。【结果】正常组气囊-面罩通气复苏成功率最差（P〈0．01），异常组食管气管导管盲插法复苏成功率最高（P〈0．01）。【结论】经口气管内插管是临床最常用和有效的建立高级气道的方法，在异常情况下，食管气管导管可作为首选。

Evaluation on bag-mask ventilation,esophageal tracheal combined tube or endotracheal intubation used as an emergent treatment for cardiopulmonary resuscitation

Objective] To explore the value of bag-mask ventilation, esophageal tracheal combined tube and endotracheal intubation used in the patient as an emergent treatment for cardiopulmonary resuscitation. Methods] A total of 351 cases of cardiac respiratory arrest were divided into two groups according to the throat anatomical difference, that is , the normal group and the abnormal group. Each group was randomly divided into three groups again according to the measures to provide artificial airway. Group A： providing bag-mask ventilation as soon as CPR began; Group B： intubate esophageal tracheal combined tube with blind way and Group C： endotracheal intubation were adopted through the mouth. The average time of intubations, oxygen saturation and successful rate of cardiopulmonary resuscitation were used as comparisort Results] Bag-mask ventilation was the worst for successful rate of cardiopulmonary resuscitation in the normal group. But esophageal tracheal combined tube is the best in the abnormal group. Conclusions] Endotracheal intubation is a common and effective method for the establishment of the high airway approach and in abnormal circumstances esophageal tracheal combined tube can be used as first choice.
