<strong>Objective</strong><span style="font-family:;" "=""><span style="font-family:Verdana;"><strong>: </strong>To evaluate the clinical value of transcranial color Doppler ultrasound (TCCD) in assessing cerebral function after cardiopulmonary resuscitation (CPR). </span><b><span style="font-family:Verdana;">Methods</span></b><span style="font-family:Verdana;">: A prospective study was conducted in 52 patients with cardiac arrest treated by CPR from January 2018 to January 2020, and its clinical data were analyzed</span></span><span style="font-family:Verdana;">. </span><span style="font-family:;" "=""><span style="font-family:Verdana;">According to classification of cerebral performance category (CPC), 31 cases (CPC grade 1 - 2) were selected in the good prognosis group and 21 cases (CPC grade 3 - 5) in the poor prognosis group. The cerebral blood flow was measured by transcranial Doppler ultrasound (TCCD) 24 h after CPR, and the differences were compared between the two groups in stroke index, diastolic blood flow velocity (Vd), systolic peak blood flow velocity (Vs) and mean peak blood flow velocity (Vm). The ROC curve of cerebral blood flow after CPR was drawn to predict the prognosis of brain function. </span><b><span style="font-family:Verdana;">Results</span></b><span style="font-family:Verdana;">: The data showed that the pulsatility index of middle cerebral artery of the poor prognosis group decreased within 24 h</span></span><span style="font-family:Verdana;">;</span><span style="font-family:Verdana;">the difference between the two groups was statistically significant (p < 0.05);the Vd, Vs, Vm increased in the good prognosis group</span><span style="font-family:Verdana;">;</span><span style="font-family:;" "=""><span style="font-family:Verdana;">the difference between the two groups was statistically significant (p < 0.05).
