简要总结
he purpose of this study is to determine the efficacy and safety of remote ischemic conditioning for acute ischemic stroke.
详细描述
In this study, 912 cases of ischemic stroke in 48 hours were included in 5 centers in China according to the principle of random, double-blind 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, 7 days in a row . Two groups will be followed up for 90 days to evaluate the efficacy and safety of remote ischemic conditioning therapy.

研究组 & 干预措施
RIC+Standard medical treatment
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 inflations of a blood pressure cuff to 200 mm Hg. RIC will be conducted twice daily for 7 days. Additionally,the patients will be treated with standard medical treatment according to Guidelines for diagnosis and treatment of acute ischemic stroke in China 2014
干预措施: Remote ischemic conditioning (Procedure)
Sham RIC+Standard medical treatment
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 inflations of a blood pressure cuff to 60 mm Hg. RIC will be conducted twice daily for 7 days. Additionally,the patients will be treated with standard medical treatment according to Guidelines for diagnosis and treatment of acute ischemic stroke in China 2014

结局指标
主要结局
Proportion of patients with Modified Rankin Scale (mRS) Score 0-2
时间窗: 3 months
The primary outcome measure of efficacy is the modified Rankin Scale (mRS) dichotomized to define good functional outcome as mRS 0-2 at 90 days.score, dichotomized to define good functional outcome as mRS 0-2 at 90 days.
次要结局
- NIHSS Score at end of 7th day of treatment(7 days)
- Changes of hematological indicators(48h; 7days)
- mRS Score at end of 7th day of treatment(7 days)
- Barthel Index at end of 7th day of treatment(7 days)
