A study was undertaken to determine the incidence of failures and complications of EGTA. The life history of 31 airways was followed. Ten failed prior to 5 usages. Paramedics successfully intubated 88% of the patients but experienced difficulties maintaining adequate airways in 15%. While the EGTA is a valuable tool in prehospital care, its utilization to the exclusion of endotracheal intubation should be carefully considered.
开展了一项研究以确定食管气管联合导管（EGTA）的失败率和并发症发生率。对31条气道的使用情况进行了跟踪。10条在使用5次之前就出现故障。护理人员成功为88%的患者进行了插管，但有15%的患者在维持气道通畅方面遇到困难。虽然EGTA在院前急救中是一种有价值的工具，但在排除气管插管的情况下使用它时应谨慎考虑。
