Key result
Patients reported no postoperative discomfort from preoxygenation masks (median 1), which was significantly lower than anesthesiologists' estimation of patient discomfort (median 5, P<0.01).
Why the study?
Does preoxygenation via mask cause significant discomfort in patients undergoing anesthesia?
Does preoxygenation via mask cause significant discomfort in patients undergoing anesthesia?
Absolute Event Rate: 1% vs 5%
p-value: p=<0.01
Anesthesiologists significantly overestimate the discomfort patients experience from preoxygenation masks, which may contribute to reluctance in using routine preoxygenation.

Anesthesiologists overestimate preoxygenation discomfort; challenges assumptions but leaves open effects on routine practice.
Schlack et al. (2001) conducted a letter in Patients undergoing general anesthesia (n=176). Preoxygenation mask vs. Anesthesiologists' estimation and preoperative expectations was evaluated on Discomfort on a continuous scale from 1 (no discomfort) to 10 (maximum discomfort) (p=<0.01). Patients reported no postoperative discomfort from preoxygenation masks (median 1), which was significantly lower than anesthesiologists' estimation of patient discomfort (median 5, P<0.01).
