Effect of Acetaminophen on Neurological Outcome in Acute Ischemic Stroke Patients Undergoing Endovascular Treatment

Neuro-inflammation response plays an important role in the development of acute ischemic stroke(AIS). The aim of this study was to conduct a prospective randomized controlled study on the effect of acetaminophen on long-term neurological prognosis in AIS patients undergoing endovascular treatment(EVT). The primary outcome was the incidence of neurological independence (mRS 0-2, modified Rankin scale) at 90 days after surgery. The secondary outcome measures were early neurological outcome (NIHSS score at 7 days after surgery or at discharge) and the incidence of symptomatic intracerebral hemorrhage during hospitalization. This study explored the effect of acetaminophen on the prognosis of neurological function of patients, and the expected results provide evidence of safety and effectiveness for acetaminophen to improve the prognosis of neurological function of patients, and provide theoretical and practical basis for the subsequent "new use of old drugs" of acetaminophen and large sample and multi-center clinical research or clinical application.
