Objective Effects of Remifentanil combined with Gastrodin injection on cerebral oxygen metabolism and early postoperative cognitive function in patients undergoing laparoscopic surgery for cervical cancer. Methods 107 cases of laparoscopic cervical carcinoma were randomly divided into observation group (54 cases) and control group (53 cases), the control group received anesthesia induction therapy based on Remifentanil, the observation group was given intravenous Gastrodin injection to 120h after operation on the basis of control group. the brain oxygen metabolism and brain injury related indexes 6h, 12h, 72h and 120h after operation were observed, and the preoperative cognitive function and postoperative cognitive function of two groups after 6h, 1d, 3d and 5d were evaluated by using Mini-Mental State Examination (MMSE) test method. Results Compared to the preoperative data, the oxygen saturation of the internal jugular vein (SjvO22) and cerebral oxygen saturation (rSO2) of two groups after 6h of operation was significantly decreased (p
