经颅多普勒超声在重度颅脑损伤中的临床应用OA

Objective To investigate the clinical effect of transcranial Doppler(TCD)in severe craniocerebral injury.Methods A total of 45 patients with severe craniocerebral injury who underwent decompression surgery for the bone flap were selected from February 2018 to March 2023 in Suqian First Hospital.CT and TCD examinations were performed in all patients,and the correlation between Helsinki CT score and TCD parameters was analyzed.Among them,37 patients who underwent intracranial pressure(ICP)monitoring were divided into normal ICP group(n=3),mildly elevated ICP group(n=14),moderately elevated ICP group(n=11)and severely elevated ICP group(n=9)according to different ICP levels.TCD parameters of the four groups were compared.Results Helsinki CT score was positively correlated with pulsatility index(PI)and resistance index(RI)(r=0.91,0.89,P<0.01),and was negatively correlated with the end of diastolic velocity(Vd)(r=-0.92,P<0.01).Helsinki CT score was not correlated with systolic peak velocity(Vs)(r=-0.39,P=0.08).There were significant differences in PI,Vd and RI among patients with different ICP(P<0.05).There was no significant difference in Vs among patients with different ICP(P>0.05).Conclusion TCD can better reflect the patient's condition,can play an early warning role in the deterioration of the disease,and has high clinical application value.
