Acute Ischemic Stroke
Conditions
Brief summary
The purpose of this study is to determine the efficacy and safety of remote ischemic conditioning for acute ischemic stroke.
Detailed description
In this study, 2210 cases of ischemic stroke in 72 hours were included in 10 centers in China according to the principle of random, and parallel control. The experimental group receive basic treatment and remote ischemic conditioning for 200mmHg, 2 times per day for 7 consecutive days. The control group receive basic treatment and remote ischemic conditioning control for 60mmHg, 2 times per day for 7 consecutive days. Two groups will be followed up for 90 days to evaluate the efficacy and safety of remote ischemic conditioning in treating acute ischemic stroke.
Interventions
PROCEDURERemote ischemic conditioning
Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 200 mm Hg.
PROCEDURESham remote ischemic conditioning
Sham remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 60 mm Hg.
