Implementing accurate blood pressure management under TCD monitoring

Control blood pressure according to guidelines

Accurate monitoring of blood pressure is carried out under TCD monitoring, that is to maintain （mean flow velocity）MFV or （pulse index）PI target blood pressure. The target values of MFV and PI are MFV>37cm/s of （middle cerebral artery)MCA, PI < 1.34cm/s, aMFV>40cm/s of (basilar artery)BA, PI < 0.8cm/s.

TCD shows that when the MFV of MCA or BA is lower than the target value, the blood pressure is reduced or discontinued according to the insufficiency of blood flow. and the current blood pressure is maintained once MFV is met. TCD showed that the PI index of MCA or BA was higher than the target value . The blood pressure reduction was treated by excessive perfusion: intravenous infusion of blood pressure drugs , once PI index is up to the standard, maintaining the current blood pressure.

the incidence of 72 hours in National Institute of Health stroke scale increased more than 4 points or National Institute of Health stroke scale Ia score more than 1 points

prognosis of nerve function use Modified Rankin Scale,0~3 is good prognosis and 4~6 is poor prognosis.
