Sleep Longitudinal Exploration of the Experience of Patients

Many epidemiological studies report that insomnia is common after fifty years in the general population but also in the post-operative period of surgery. Preoperatively, sleep quality can be disturbed by fear of general anesthesia and surgery. Postoperatively, it seems to be altered by pain, the ambient environment and night care. Literature shows that the occurrence of post-operative sleep disorders seems to lead to (increased) hypnotic consumption in patients who did not consume them in the pre-operative phase with known risks of dependence. Nowadays , general anesthesia is widely practiced worldwide. However, despite continuous improvement in techniques, a large number of patients still experience poor quality postoperative sleep, even with short-term anesthesia. It therefore appears that general anesthesia disrupts the circadian rhythm of patients, even if the mechanisms are still poorly understood. Thus, sleep deprivation could be responsible of physiological alterations that are still unknown, such as delayed healing or impaired respiratory muscle performance, promoting postoperative complications. The aim of this study is to identify the factors impacting the quality of sleep of patients undergoing scheduled surgery during the first postoperative night. And its implication on the occurrence of drowsiness described by the patient the day after their surgical intervention.
