In a prospective study to evaluate the respiratory effectiveness of the esophageal gastric tube airway (EGTA) in the prehospital setting, we analyzed arterial blood samples from 43 victims of out-of-hospital cardiopulmonary arrest managed with the EGTA. Five minutes after emergency department endotracheal intubation, arterial blood gas analysis was repeated for comparison. During EGTA ventilation, the mean arterial PO2 measured 83.6 +/- 110.4 mm Hg; endotracheal intubation increased the mean PO2 to 189 +/- 167.5 mm Hg. During EGTA ventilation, the mean arterial PCO2 measured 77.1 +/- 34 mm Hg; endotracheal intubation decreased the mean PCO2 to 57.8 +/- 34.4 mm Hg. We conclude that endotracheal intubation remains the procedure of choice for airway management in the victim of cardiopulmonary arrest.
在一项前瞻性研究中，为评估院前环境下食管胃管气道（EGTA）的呼吸效果，我们分析了43例接受EGTA治疗的院外心脏骤停受害者的动脉血样本。在急诊科进行气管插管5分钟后，重复进行动脉血气分析以作比较。在EGTA通气期间，平均动脉血氧分压为83.6±110.4毫米汞柱；气管插管后平均血氧分压升至189±167.5毫米汞柱。在EGTA通气期间，平均动脉血二氧化碳分压为77.1±34毫米汞柱；气管插管后平均二氧化碳分压降至57.8±34.4毫米汞柱。我们得出结论，气管插管仍然是心肺骤停受害者气道管理的首选方法。
