研究概览
简要总结
The aim of the study is to see whether the hypotension that develops during spinal anesthesia in cesarean section patients causes a decrease in the postoperative cognitive functions of the patient. If the results show a decrease in functions due to the effect of hypotension, it will be necessary to carry out aggressive prevention/treatment of hypotension in cesarean section patients.
详细描述
A total of 150 female patients (75 in each group) between the ages of 18-40 who will undergo caesarean section with spinal anesthesia in the obstetric operating room of Ankara Bilkent City Hospital in ASA 2, 3rd categories will be included in the study.
Patients will be divided into two as hypotensive and non-hypotensive patients in spinal anesthesia with routine doses, and all patients will be given a mini mental test at preop and post op 1st hour. (Hypotension, MAP(mean artery pressure)<65 mmHg, or SAP(systemic arterial pressure) < 30% will be considered as an initial value.) Patients who are hypotensive and need ephedrine will be included in the hypotensive group, and patients without hypotension will be included in the normotensive group. Those with an initial mini mental test score below 24 will not be allowed to study. At the end of the research, the mental test scores of the two groups will be compared and the effect of hypotension will be evaluated.
The patient's name-surname, age, protocol number, indication for cesarean section, method of regional anesthesia applied, sensory block level, Bromage score, side effect follow-up, first ten minutes after the procedure, every two minutes, up to half an hour, and every fifteen minutes after thirty minutes, systolic artery pressure, diastolic artery pressure, average arterial pressure, pulse and ephedrine (if used) will be recorded.
Preoperative, Postoperative first hour Mini Mental Test Score will be administered and recorded

研究组 & 干预措施
Hypotensive group

结局指标
主要结局
Change in postoperative cognitive function related with hypotension in cesarean section
时间窗: Preoperative (in 10 minutes before operation) to postoperative first hour.
Postoperative cognitive dysfunction is defined as the decrease in postoperative 1st hour mini-mental test results compared to preoperative results.Higher scores of mini-mental test mean a better outcome.By comparing the difference between the preoperative and postoperative mini-mental test results of the patients in the two arms, It will be observed whether there is a cognitive function difference between the groups.
