After day and a half, can STROKE VICTIM have serious complications in ICU?

the answer to all your questions is YES...it is normal to still be in the ICU where he can be closely monitored...he is still at risk for worsening condition, other body system failures, and even death...it is good that he did not die before reaching the hospital, it is good that he was brought to the hospital quickly, it is good that the medical treatment has stabilized his condition...hang in here, recovery from stroke can be a long process...
