CompARing Between CO2 Phenylephrine and Phenylephrine Only Treatment in Patients With proGrEssing Cerebral infarctioN

• Status: NOT_YET_RECRUITING
• Trial end date: 2027-12-01

Summary

Progressing stroke is associated poor functional outcome and neurological deficit.

Currently, no treatment for progressing stroke is recommended on the guideline.

Carbogen is a mixture of 5% CO2 with 95% O2. Carbogen is safe and it is used for the treatment of sudden sensory neural hearing loss or ocular ischemia.

CO2 dilate cerebral arteriole and concentration of CO2 is correlated with cerebral blood flow.

Increased cerebral blood flow following dilation of cerebral arteriole by CO2 might halt and revert progressing stroke.

Induced hypertension is alternative treatment of progressing stroke. Increasing blood pressure also induce cerebral blood flow. Phenylephrine is an 1 agonist, phenylephrine act on peripheral artery and little effect on cerebral artery or heart. Several studies reported that the effectiveness of phenylephrine on progressing stroke.

Therefore, this study will compare the effectiveness of carbogen + phenyleprhine versus phenlyephrine in progressing stroke patients.
