About

The purpose of this study is to determine the impact of remote ischemic conditioning on dynamic cerebral autoregulation in patients with acute ischemic stroke receiving intravenous thrombolysis.

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 . Both groups underwent dynamic cerebral autoregulation measurements at days 1 to 2 and 7 to 10 of onset and recorded the relevant indexes, and blood samples were collected before and 24 hours after intravenous thrombolysis, we aimed to determine the impact of remote ischemic conditioning combined with intravenous thrombolysis on dynamic cerebral autoregulation in acute ischemic stroke patients. We hypothesized that remote ischemic conditioning would improve dynamic cerebral autoregulation in patients with acute ischemic stroke receiving intravenous thrombolysis.

80 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 mmHg. RIC will be conducted twice within 6 to 24 hours from thrombolysis.
Treatment:
Procedure: remote ischemic conditioning
control group
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 mmHg. RIC will be conducted twice twice within 6 to 24 hours from thrombolysis.
