Ciprofol vs Propofol for Hemodynamic Stability in Patients Having General Anesthesia for Endovascular Thrombectomy After Ischemic Stroke

Sponsor: RenJi Hospital

Summary

Endovascular therapy (EVT) improves the prognosis of patients with acute ischemic stroke (AIS). EVT has been established as a standard of care for AIS caused with large vessel occlusion based on numerous randomized controlled trials. However, despite extensive attention to post-EVT blood pressure management as a potentially modifiable factor, the ability to achieve high reperfusion rates does not consistently translate into functional independence for a substantial number of patients. Thus, the focus has turned to the intra-procedural period, where blood pressure management may play a critical but underexamined role in determining functional outcomes independent of post-EVT care. Guideline recommendation to maintain the blood pressure lowered to 185/110 mmHg before the EVT procedure in patients who have not received intravenous thrombolysis therapy. However, studies of blood pressure before reperfusion in this patient group have produced conflicting results. Thus, although randomized trials evaluating pre-thrombectomy blood pressure targets are yet unavailable, accumulating evidence suggests that active blood pressure lowering before reperfusion may be harmful, which underscores the importance of maintaining hemodynamic stability during the EVT procedure. In this context, anesthetic management is a key determinant of intraprocedural blood pressure control. Propofol is the most commonly used general anesthetic during EVT surgery. However, propofol is a powerful venodilator and often provokes hypotension which may be especially detrimental in AIS patients. Ciprofol, a novel anesthetic/sedative, has been proven to possess excellent efficacy and safety which provides definitive general anesthesia/sedation while minimizing respiratory and hemodynamic depression. Before and during EVT, patients with hemodynamic stability may have better outcomes. Using ciprofol as the anesthesia agent may reduce the incidence and severity of hemodynamic instability during EVT. Therefore, it is of significant research value to investigate whether the use of ciprofol for general anesthesia is beneficial in AIS patients undergoing EVT.
