Five patients requiring general anesthesia but presenting with compromised airways were successfully intubated by blind awake intubation with the aid of regional anesthesia and the use of appropriate sedation. Arterial blood gases were collected at three intervals: presedation, postsedation, and postintubation. ⋯ Supplemental oxygen is suggested to avoid the effects of arterial desaturation during the sedation process. If oxygen is not administered, the risk of moderate hypoxia associated with blind awake intubation must be considered along with alternative problems including loss of protective reflexes or the inability to ventilate during induction and intubation via a direct technique.

End tidal carbon dioxide and respiratory rate measurement during conscious sedation through a nasal cannula.
During the administration of central nervous system depressant drugs for dentistry or surgery, it may not always be possible to continuously measure respiratory physiology. We present a simple and efficacious method of monitoring respiration during dental or surgical procedures in which a conscious sedation technique is used.
