Insomnia and wake up and recovery from anesthesia: a prospective observational study

Purpose: The aim of this study was to investigate whether wake up and recovery from anesthesia is earlier or later in patients with insomnia.Material and Methods: This study included adult patients who were scheduled for elective ureteroscopy under general anesthesia. Using the Jenkins-Sleep Questionnaire (JSQ), the patients were separated into two groups: Insomnia Group and Control Group. Anaesthesia was standardized. After anesthesia induction, 4-6 % desflurane in nitrous oxide/oxygen (60-40%) concentration at flow of 3 L min over bar 1 was administered. The parameters recorded were noninvasive arterial blood pressure, heart rate, peripheral oxygen saturation, end-tidal carbon dioxide values, inspiratory and expiratory concentrations of desflurane, anesthesia time, surgery time, time of eye opening, time of transfer to the recovery room. Pain was assessed with a Visual Analogue Scale (VAS) and recovery with the Modified Aldrete Recovery Score (MARS).Results: Evaluation was made of 80 patients, comprising 25 females and, 55 males, grouped as 42 patients in the insomnia group and 38 in the control group. The demographic and hemodynamic data were not significantly different between the groups. The time of eye opening, transfer to the recovery room, VAS and MARS values were similar in both groups. When operation times were classified as < 30 min. and >= 30 min, no significant differences were determined between the groups in respect of wake up, recovery and pain parameters.Conclusion: Compared with normal sleepers, patients with insomnia showed no differences in respect of wake up and recovery from anesthesia.
