Abstract: Objective:To investigate the clinical guidance of emergency bedside ultrasound imaging for abdominal blunt trauma and compare with the CT examination.Methods:166 patients,used bedside ultrasound and CT scan,then compared the diagnosis of liver,spleen and kidney damage in terms and their surgical treatment guidance.Results:Bedside ultrasound and CT scan showed no overall statistically significant,especially in the diagnosis of hematoma,parenchymal damage and even rupture of the coincidence rate with CT scan(P>0.05),implementation of the CT examination time was spent longer than bedside ultrasound examination(P<0.05).Conclusion:For the diagnosis of abdominal blunt trauma,bedside ultrasound diagnosis has a high diagnosis rate,compared with the CT scan,it can effectively save the time required for diagnosis of patients,to avoid moving patients,so it is a better method of early diagnosis.
