This study was conducted to compare propofol dose requirements between patients with and without sleep quality disorder (SQD) in order to achieve the same depth of anesthesia. Methods: In this comparative study, adult patients who were candidates for elective cataract surgery under general anesthesia in American Society of Anesthesiologists (ASA) class I or II were included. Using a validated questionnaire, patients were divided into two groups with Pittsburgh Sleep Quality Index (PSQI) higher and lower than five. Pre-induction with midazolam 0.02 mg/kg and fentanyl 2 µg/kg was administered 3 min before induction. Induction and 1-hour maintenance doses of propofol to achieve and maintain bispectral index score (BIS) 40–60 were measured and compared in the two groups. Results: Seventy patients, 47 of which (67.1%) were female, with the mean age of 63.83 ± 10.67 years were enrolled; 35 in SQD group and 35 in normal group. Baseline and demographic characteristics were not significantly different between the two groups. BIS score after pre-induction was significantly lower in SQD group compared with normal group (p = 0.002). Propofol dose at the time of induction and also 1 hour after induction was significantly lower in SQD group compared to normal group (p < 0.001). Total dose of propofol required was significantly lower in SQD group (209.26 ± 81.02) compared to normal group (342.91 ± 100.59) (p < 0.001). Based on the unstandardized Beta of multivariable linear regression model, mean total propofol requirement in SQD group was 113.43 mg less than normal group (p < 0.001). Conclusion: In the current study, induction and maintenance doses of propofol for general anesthesia were significantly lower in patients with SQD, in comparison with normal patients.
