This study compares two similar groups of patients in cardiopulmonary arrest with ventricular fibrillation (VF). In the survival study group of 296 patients, 148 patients received an endotracheal tube airway (ETA) and 148 patients received an esophageal gastric tube airway (EGTA), the improved version of the esophageal obturator airway (EOA). Survival rates, both short term (ETA = 35.8%, EGTA = 39.1%) and long term (ETA = 11.5%, EGTA = 16.2%), and neurological sequelae of survivors showed no statistically significant difference between the two groups (P greater than .05). In addition, we found that success and complication rates of intubation were similar. Training time was longer for the ETA. We conclude that both airways have a place in the prehospital setting.
本研究比较了两组患有心室颤动（VF）的心脏骤停患者。在296例患者的生存研究组中，148例患者接受了气管内插管气道（ETA），148例患者接受了食管胃管气道（EGTA），即食管阻塞气道（EOA）的改良版。两组患者的短期生存率（ETA = 35.8%，EGTA = 39.1%）和长期生存率（ETA = 11.5%，EGTA = 16.2%）以及幸存者的神经后遗症均无统计学显著差异（P大于0.05）。此外，我们发现插管的成功率和并发症发生率相似。ETA的培训时间更长。我们得出结论，两种气道在院前环境中都有一席之地。
