Objective: To determine the effect of preoperative fasting times on patient comfort. Method: This descriptive study was carried out with a total of 232 patients who were hospitalized and operated in a surgical clinic of a university hospital in Aydın, between January 17, and February 16, 2017. Data were collected with "Patient Information Form" and "Perianesthesia Comfort Scale". In the analysis, descriptive statistics and Spearman correlation statistics were used because the variables to be examined in the analysis did not show normal distribution in Shapiro-Wilk test. Results: Most (81.9%) of the patients participating in the study underwent elective surgery and 52.2% of them received general anesthesia. It was determined that 88.4% of the patients had drunk water at the latest , 25% of them were very thirsty, 15.5% felt starving and 7.3% of them experienced headaches. While 96.6% of the patients were informed about the fasting before the operation, 42.7% stated that they received this information from the nurse but 74.6% did not know why they should be on empty stomach before the surgery. Mean preoperative fasting period was 14.80±6.06 hours, mean duration of lfluid fasting was 11.89±4.91 hours, and Perianesthesia Comfort Scale score was 118.90±12.50. There was no correlation between fasting periods of the patients for solid foods, and liquid foods and perianesthesia comfort scale scores. Conclusion: Despite prolonged preoperative fasting period higher Perianesthesia Comfort Scale scores demonstrate that perianesthesia alone has no effect on patient comfort.
