Experience with 29 000 cases in which the oesophageal obturator airway has been used in cardiopulmonary resuscitation indicates its safety, efficacy, and ease of use. Blood gases, fractional inspired oxygen, and pH were measured in 18 patients given both the oesophageal obturator airway and the endotracheal tube; there was no significant difference between the two. The former was found to be inserted more rapidly and reliably; moreover, paramedical staff are quickly trained to use it. It is concluded that the oesophageal obturator airway provides the technique of choice whenever ideal conditions and facilities--and trained staff--for endotracheal intubation are not immediately available.
在29000例心肺复苏中使用食管阻塞气道的经验表明了其安全性、有效性和易用性。对18例同时使用食管阻塞气道和气管内插管的患者进行了血气、吸入氧分数和pH值测量；两者之间无显著差异。发现前者插入更快且更可靠；此外，辅助医务人员能很快学会使用它。得出的结论是，每当无法立即获得气管插管的理想条件、设施及训练有素的人员时，食管阻塞气道就是首选技术。
