Szczegółowy opis
Remote ischemic post-conditioning, which consists of several brief cycles of intermittent ischemia-reperfusion of the arm or leg, may potentially confer a powerful systemic protection against prolonged ischemia in a distant organ.
Numerous reports have confirmed it strongest endogenous neuroprotection against brain injury after stroke.
Ren et al demonstrated that remote ischemic post-conditioning (RIPC) performed in the hind limbs can not only significantly reduce the stroke volume within 3 hours in rat model, but also ameliorate the outcome of the behavioral test.
A long-term repeated RIPC therapy can also help improving neurological functions.
A combination of RIPC and tPA can help with neuroprotection which improves the neurological functions.
Thus, it is meaningful to transform these basic experimental results to the clinical treatment.
In the RECAST-1 trial, RIC has shown it safety and efficiency in AIS patients without tPA.
However, there is no further explanation for the patients with IVT.
Thus, in this study, we aim to demonstrate the efficiency and safety of RIPC in AIS patients performed rt-PA within 4.5 hours.

Grupa uczestników / Arm |
Interwencja / Leczenie |
|---|---|
|
Eksperymentalny: RIC group
The upper limb ischemic conditioning is composed of five cycles of bilateral upper limb ischemia intervened by reperfusion, which is induced by two cuff placed around the upper arms respectively and inflated to 200 mm Hg for 5 minutes followed by 5 minutes of reperfusion by cuff deflation.
This therapy started within 2 hours after r-tPA thrombolytic therapy.
In addition, all participants receive a standard clinical therapy.

W tym badaniu zdalne leczenie niedokrwienne kondycjonujące składało się z pięciu cykli obustronnego niedokrwienia kończyn górnych z interwencją reperfuzji, która została wywołana przez dwa mankiety umieszczone odpowiednio wokół ramion i napompowane do 200 mm Hg przez 5 minut, a następnie przez 5 minut reperfuzji przez deflację mankietu.

The score of Modified Rankin scale score
Ramy czasowe: measured at baseline(before RIPC),24 hours, at 5-7 days,30±7 days, 90±7 days
|
The Modified Rankin Scale Score (mRS) is the most comprehensive and most widely used primary outcome measurement to assess the neurological functional disability in contemporary acute stroke trials.
The mRS is an ordinal, graded interval scale that assigns patients among 7 global disability levels, which ranges from 0 (no symptom) to 5 (severe disability) and 6 (death).
We will use mRS to evaluate the degree of disability or dependence during daily activities.
The mRS will be assessed by certified study investigator, who is blinded to the treatment assignment, at 90 days postoperation.
The distribution of mRS will be compared between groups

|
National Institute of Health Stroke Scale (NIHSS) is considered as a standardized assessment of neurological functions in the acute phase of stroke, and it is generally used to quantify patient's neurological impairments on 15 items in 11 fields of different neurological status.The score of the scale ranges from 0 to 42.And higher score indicates worse neurological function.
