Key result
General anesthesia was associated with a 0.13% incidence of awareness with recall, with higher ASA physical status increasing this risk (OR 2.41; 95% CI 1.04-5.60).

Awareness with recall during general anesthesia occurs in approximately 0.13% of surgical patients in the US, with higher risk observed in patients with greater ASA physical status.
Sebel et al. (2004) conducted a cohort in Surgery under general anesthesia (n=19,575). General anesthesia was evaluated on Incidence of awareness with recall (OR 2.41, 95% CI 1.04-5.60). General anesthesia was associated with a 0.13% incidence of awareness with recall, with higher ASA physical status increasing this risk (OR 2.41; 95% CI 1.04-5.60).
