However, its prominent drawback is circulatory depression. Our research team previously proposed an individualized dosing method for the titration of propofol. We then compared the effects of different titration rates of propofol on hemodynamics and stress during general anesthesia induction. It was found that the incidence of hypotension during the induction period was lower in the 0.5 mg\u002Fkg\u002Fmin group, with lower stress levels and faster postoperative recovery. However, this group still had a 25.3% incidence of hypotension. Therefore, we plan to further study the differences in hemodynamics, depth of anesthesia, stress response, and postoperative recovery in three groups of patients induced with a constant infusion rate of propofol at 0.5 mg\u002Fkg\u002Fmin titrated to an OAA\u002FS score of 1, an OAA\u002FS score of 2, and BIS ≤ 60, combined with remifentanil 2 μg\u002Fkg. This study aims to explore the appropriate propofol titration endpoint during general anesthesia induction to maintain stable perioperative haemodynamics and achieve rapid postoperative recovery.",[28,29],"Anesthesia, General","Hemodynamics",[31],"titration of propofol","NOT_YET_RECRUITING","2024-12-01",{"date":35,"type":36},"2024-12-04","ACTUAL",{"date":38,"type":22},"2025-02-20",{"date":40,"type":22},"2025-08-20",{"name":42,"class":43},"SanQing Jin","OTHER",""]
