mini mental state assessment test: Anesthesia management during surgery for this disease in the postoperative period should be carefully planned. It will be important to examine the neurocognitive effects of anesthesia management in the postoperative period in this patient group. In this study, the frequently used Mini mental state assessment test and Mini-cog test will be used. With mini mental state assessment, the patient is asked a number of simple questions to evaluate cognitive functions and each question has certain points. Changes in these score levels preoperatively and postoperatively will be compared within each patient. At the end of the study, preoperative and postoperative changes will be compared statistically between the groups.

Study summary
This prospective study involves assessing neurocognitive function in patients undergoing laparotomic gastrointestinal surgery. Mini Mental state Assessment test and Mini-Cog tests will be conducted at multiple intervals preoperatively and postoperatively. Anesthesia management, vital signs, drug consumption, and blood gas values will be recorded throughout the surgery. After all neurocognitive evaluations of the patients are performed at planned intervals for 1 week, the levels of dexmedetomidine and remifentanyl consumed by the patients in the peroperative period will be determined from the anesthesia follow-up sheet and the total duration and amount used will be recorded. At the end of the study, the relationship between neurocognitive values and dexmedetomidine will be compared.

Primary outcome measure(s)
Decrease in Mini Mental State Assessment test — Preoperative 24 hours before, in the preoperative operating room, at the 1st postoperative hour, on the 1st, 3rd, 5th postoperative days. Patients who will undergo laparotomic lower and upper gastrointestinal system surgery will be given a mini mental state assessment test at the preoperative 24th hour, before and after surgery, and on the 1st, 3rd, and 5th postoperative days. In this test, the patient's neurocognitive status will be evaluated by asking simple questions that investigate their mental characteristics. Each question has a score and the total score indicates the patient's condition. In these patients, this test will be repeated at regular intervals after surgery and postoperatively and the results will be recorded. High scores on this test indicate good neurological stability, whereas falling is associated with poor neurological status. Changed in the value as a result of this test will be investigated.
