HyperBaric Oxygen Therapy After ACute Thrombectomy in Acute Ischemic strOke Due to Large Vessel occlusioN

Обзор

The purpose of this RCT trial is to evaluate whether the sequential hyperbaric oxygen therapy can improve the 90-day functional outcome in patients with acute large vessel occlusion ischemic stroke after endovascular treatment.

Подробное описание

This is a multicenter, prospective, open-label, endpoint-blinded, randomized controlled trial with a 1:1 ratio, comparing the effect of hyperbaric oxygen therapy plus standard medical treatment versus standard medical treatment alone after endovascular treatment in patients with acute large vessel occlusion ischemic stroke. The primary outcome is modified Rankin Scale (mRS) score distribution at 90 days (±14 days) after randomization.

• Другое Hyperbaric oxygen therapy plus standard medical treatment
  The first treatment was initiated within 24 hours after enrollment. The treatment plan is: in a medical multi-person air pressurized chamber, the treatment pressure is 0.2 MPa, the pressurization time is 30 minutes, the mask inhales 100% oxygen for 60 minutes, and the decompression time is 30 minutes. Once a day, once on the 1st, 2nd, and 3rd days after enrollment (i.e., within the 24-hour, 48-hour, and 72-hour time window), a total of 3 times. Vital signs such as blood pressure, heart rate, and
• Другое Standard medical treatment
  According to the current guideline "2026 Guideline for the Early Management of Patients With Acute Ischemic Stroke: A Guideline From the American Heart Association/American Stroke Association" "Chinese Guidelines for the Diagnosis and Treatment of Acute Ischemic Stroke 2023", they receive standard medical treatment and monitoring (including antithrombotic drugs, lipid-lowering drugs, blood pressure management, etc.), not entering the hyperbaric oxygen chamber for treatment.
