Filter by:To observe whether adjusting the level of intraoperative controlled hypotension through cerebral oxygen saturation monitoring can improve postoperative cognitive function(POCD) and reduce postoperative neurological complications, a prospective randomized controlled study method will be used in this study. 400 elderly patients undergoing shoulder arthroscopic surgery under general anesthesia combined with brachial plexus block will be selected. They will be randomly divided into control group and experimental group according to whether cerebral oxygen saturation monitoring was used during the operation. The control group maintain the target blood pressure only according to the controlled hypotension guideline, and the experimental group adjust the controlled hypotension level under the guidance of cerebral oxygen saturation monitoring. The general condition, operation, anesthesia and hospitalization related data of the patients will be recorded.
Video-Assisted Thoracoscopic Surgery(VATS) is among the most common and disabling persistent pain and inflammation conditions, with increasing prevalence in the developed world, and affects women to a greater degree than men. And sleep disruption also remains a challenging problem in surgical settings. Postoperative sleep disturbances (POSD) are defined as changes in the sleep structure and quality of patients during the early stages after surgery, which are manifested as significantly shortened rapid eye movement (REM) sleep, prolonged awake time, and sleep fragmentation. Long-term POSD may increase the risk of postoperative delirium or cognitive dysfunction and delay recovery, thereby worsening the patient's physical condition. The aim of the study was to investigate the effect of sex differences on postoperative pain, inflammation, sleep quality and cognitive function among patients who have undergone video-assisted thoracoscopic surgery under general anesthesia.
