DIAGNOSTIC ACCURATENESS OF ULTRASOUND IN RECOGNITION OF VISCERAL INJURY IN BLUNT TRAUMA TO ABDOMEN

Introduction: Blunt abdominal trauma (BAT) is common in the emergency department. The present study aims to determine the incidence of spleen injuries following blunt abdominal trauma and the typical injuries leading to it. Spleen trauma is of great medical and legal importance. Aim: To determine the diagnostic accuracy of ultrasound in the detection of visceral injuries in blunt abdominal trauma, taking into account CT as the gold standard. Methods: This study cross-sectional was conducted at the Department of Diagnostic Radiology, DHQ Hospital Dera Ismail Khan for one-year duration from April 2019 to April 2020. The sample size was calculated using the WHO sample size calculator assuming a sensitivity of 93.3% 2.6, a specificity of 85% 2.6, an incidence of 65% 3, a desired precision of 10% and a confidence interval of 95%. It turned out to be 141. The sampling was done using the random sampling technique. Results: In this study, the mean age was 30 years with an SD ± 2.13. Sixty-seven percent of patients are male and 33% of patients are female. The diagnostic accuracy of ultrasound of visceral trauma in blunt abdominal trauma was analyzed: ultrasound sensitivity 93.5%, specificity 84.8%, positive predictive value 82.8%, negative predictive value 94.3%, and diagnostic effectiveness 88.65%. Conclusion: Ultrasonography has high diagnostic efficacy in screening patients with blunt abdominal trauma. Keywords: ultrasound, computed tomography, visceral trauma, blunt abdominal trauma
