		        	Abstract:
			       	
			       		
				        
				        	 Objective:To evaluate the accuracy of ultrasound-determined end-diastolic velocity (EDV) of central retinal artery (CRA) in diagnosing postoperative low cerebral perfusion pressure (CPP) in the patients with craniocerebral trauma.
				        	
 Methods:Forty-nine patients of both sexes with brain injury, aged 18-64 yr, with body mass index of 18.5-23.9 kg/m2, were enrolled.The peak systolic velocity and EDV of CRA were determined using ultrasound at 1 day after operation.Mean arterial pressure and intracranial pressure were recorded, and CPP was calculated (CPP=mean arterial pressure-intracranial pressure).
 Results:EDV was positively correlated with CPP (r=0.746, P<0.01), and peak systolic velocity was not correlated with CPP (P>0.05). The area under the receiver operating characteristic curve for EDV in diagnosing low CPP was 0.938 (95% confidence interval 0.871-1.000), and the critical value was 3.205 (sensitivity 94.4%, specificity 76.9%).
 Conclusion:Ultrasound-determined EDV of central retinal artery can accurately diagnose postoperative low CPP in the patients with craniocerebral trauma.
