About

The purpose of this study is to determine the efficacy and safety of remote ischemic conditioning combined with intravenous thrombolysis in treating acute ischemic stroke.

Full description

In this study, cases of ischemic stroke who undergo intravenous thrombolysis within 4.5 hours from onset are included. The experimental group receive basic treatment and remote ischemic conditioning for 200mmHg, 2 times within 6 hours to 24 hours from thrombolysis. The control group receive basic treatment and remote ischemic conditioning control for 60mmHg, 2 times within 6 hours to 24 hours from thrombolysis . Two groups will be followed up for 90 days to evaluate the efficacy and safety of remote ischemic conditioning combined with intravenous thrombolysis in treating acute ischemic stroke.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Quadruple Blind

---

50 participants in 2 patient groups, including a placebo group

RIC group

Active Comparator group

Description:

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 re-perfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 200 mm Hg. RIC will be conducted twice within 6 to 24 hours from thrombolysis. Additionally,the patients will be treated with standard medical treatment according to Guidelines for diagnosis and treatment of acute ischemic stroke in China 2014.

Placebo Comparator group

Description:

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 re-perfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 60 mm Hg. RIC will be conducted twice twice within 6 to 24 hours from thrombolysis. Additionally,the patients will be treated with standard medical treatment according to Guidelines for diagnosis and treatment of acute ischemic stroke in China 2014
