We describe pharyngeal oximetry with the laryngeal mask airway in two patients with low perfusion states where finger oximetry failed.
One patient was a 47-yr-old man with septic shock and the other a 64-yr-old man with multiorgan failure. In both patients, a # 4 laryngeal mask airway with a pediatric pulse oximeter probe was inserted behind the tracheal tube. A good waveform was obtained and oxygen saturation was 0-2% lower than arterial samples.
Pharyngeal oximetry with the laryngeal mask airway is feasible in low perfusion states when finger oximetry fails.
我们描述了在两名低灌注状态且手指血氧饱和度测定失败的患者中，使用喉罩气道进行咽部血氧饱和度测定的情况。
一名患者是47岁的男性，患有感染性休克，另一名是64岁的男性，患有多器官功能衰竭。在这两名患者中，将带有小儿脉搏血氧饱和度测定探头的4号喉罩气道插入气管导管后方。获得了良好的波形，血氧饱和度比动脉血样本低0 - 2%。
当手指血氧饱和度测定失败时，在低灌注状态下使用喉罩气道进行咽部血氧饱和度测定是可行的。
