Pak J Radiol Jan ;21(3):97-101.

BACKGROUND: To evaluate sensitivity, specificity, feasibility and accuracy of ultrasound in detecting hemoperitoneum in blunt trauma patients. DESIGN: A prospective and descriptive study. PLACE AND DURATION OF STUDY: Radiology Department, Aga Khan University Hospital, Karachi from 1st Nov 2008 to 30th March 2009. SUBJECTS AND METH ODS: All victims of blunt abdominal trauma presenting to emergency room of Aga Khan University Hospital over the age of fifteen years were included in the study. Patients were excluded if a bedside ultrasound examination was not completed or expired in the early period before CT or other imaging examinations could be done or if injuries were not confirmed by laparotomy or autopsy. RESULTS: Out of the 148 adult patients, 115 were males and 33 females. Presenting age ranged from 16 to 74 years. There were 15 true positive and 131 true negative results. One case was false positive and 1 false negative. Sensitivity was 93.75%, specificity 99.24%, accuracy 98.64%, positive predictive value 93.75% and negative predictive value 99.29%. CONCLUSION: Ultrasound is safe, cost effective, sensitive, specific and accurate in detecting hemoperitoneum in patients with blunt abdominal trauma.
