About

The purpose of this study is to determine whether treatment with remote ischemic conditioning is of sufficient promise to improve outcome before conducting a larger clinical trial to examine its effectiveness as a treatment for intracerebral hemorrhage.

Full description

Intracerebral hemorrhage is a devastating disease with a high rate of severe disability and death, while no specific treatment has been proven to improve functional outcome. As a result, new approaches need to be developed to treat intracerebral hemorrhage. Animal and human trials showed treatment with remote ischemic conditioning was safe for intracerebral hemorrhage. And repetitive remote ischemic conditioning has been shown to improve sensorimotor and neuropathological outcomes following experimental hemorrhagic stroke. Therefore, we hypothesize that repetitive remote ischemic conditioning could improve functional outcome in patients with intracerebral hemorrhage. We design this prospective, multicenter, randomized controlled double-blind trial to determine whether treatment with remote ischemic conditioning is of sufficient promise to improve outcome before conducting a larger clinical trial to examine its effectiveness as a treatment for intracerebral hemorrhage.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Quadruple Blind

---

530 participants in 2 patient groups, including a placebo group

RIC+Standard medical treatment

Active Comparator group

Description:

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 2014 chinese guideline for the diagnosis and treatment of intracerebral hemorrhage.

Treatment:

Procedure: Remote ischemic conditioning

Sham RIC+Standard medical treatment

Placebo Comparator group

Description:

Sham remote ischemic conditioning (Sham RIC) is simulated by the measurement of blood pressure twice daily for 7 days.Additionally,the patients will be treated with standard medical treatment according to 2014 chinese guideline for the diagnosis and treatment of intracerebral hemorrhage.

Treatment:

Procedure: Sham remote ischemic conditioning
