Purpose: On arrival to the postanesthesia care unit (PACU), patients are observed closely for significant neurological status changes. In particular, patients require frequent neurological examinations, which include assessment of the pupils for changes and/or abnormalities.
Design: This is a prospective, nonrandomized, observational study to examine the findings of pupillary examinations by nurses using different light sources in patients with existing pupillary assessments as ordered by standard of care.
