Overview
Cataract surgery is routinely performed with anesthesia care, whereas anesthesia care for other elective, low-risk, outpatient procedures is applied more selectively. We hypothesize that sublingual melatonin will provide superior anxiolysis and sedation while maintaining a high safety profile and minimizing hemodynamic disturbances.
Description
Prevalence of anesthesia care during cataract surgery compared with other low-risk procedures; association of anesthesia care with patient, clinician, and health system characteristics; and proportion of patients experiencing a significant anxiety and hemodynamic instability during cataract surgery.
