Comparative StudyOperating room fires: part II. optimizing safety.
The second part of the authors' study on operating room fires analyzes the construct of the nasal cannula used during facial surgery for patients under conscious sedation with supplemental oxygen. This prospective study compares two common styles of nasal cannulas with a nasopharyngeal system described in their first report. ⋯ This study demonstrates that mass spectrometry oxygen readings around the face are similar to room air when the cut ends of the oxygen cannulas are passed down the nasaopharyngeal tube, whereas readings are significantly higher with the nasal cannulas. The nasopharyngeal system that the authors describe represents a significantly safer means of oxygen delivery during conscious sedation.
