Related Conditions & MeSH terms

• Pneumonia
• Stroke

Intervention

Device:
• Remote ischemic conditioning
The RIC procedure consists of five cycles of unilateral arm ischemia for 5 minutes, which was followed by reperfusion for another 5 minutes. The procedure is performed with an electric, autocontrol device with a cuff that inflated to a pressure of 200 mmHg during the ischemia period. RIC is performed within 24hours after stroke onset, and twice daily for the subsequent 7 days.
• Sham remote ischemic conditioning
The RIC procedure consists of five cycles of unilateral arm ischemia for 5 minutes, which was followed by reperfusion for another 5 minutes. The procedure is performed with an electric, autocontrol device with a cuff that inflated to a pressure of 60 mmHg during the ischemia period. RIC is performed within 24hours after stroke onset, and twice daily for the subsequent 7 days.

Secondary	Modified Rankin scale score from 0 to 1	In medical and clinical research, the modified Rankin Scale (mRS) is used to assess the degree of disability in patients after a stroke. The scale ranges from 0 to 6, where 0 indicates no symptoms and 6 indicates death.; On the mRS scale, scores from 0 to 2 usually indicate no or slight disability. Specifically: 0 points: No symptoms.; point: Symptoms present but no significant disability; able to carry out all usual duties and activities.; points: Slight disability; able to look after own affairs without assistance but unable to carry out all previous activities.; Therefore, in clinical research, if a treatment or intervention increases the proportion of patients scoring 0 to 1 on the mRS scale, it is generally considered a positive outcome. This means that more patients have a better functional status and lower degree of disability after treatment.	90 days after the onset of symptoms
