Background an Ultrasound of the Chest Is a Noninvasive Diagnostic Tool Used to Evaluate the Lungs, Mediastinum (The Chest Cavity That Houses the Heart, Aorta, Trachea, Esophagus, Thymus, and Lymph Nodes), And Pleural Space (The Area Between the Lungs and the Chest Wall). Using Ultrasound, the Internal Organs And Structures of the Chest May Be Quickly and Clearly Seen from the Outside. It Is Possible to Evaluate Heart and Lung Function Using Ultrasound. This Research Explores the Perspectives of Young Patients Who Had Emergency Chest Surgery and Afterwards Underwent a Series of Radiography Examinations. Aim the Purpose of This Research Is To Compare the Accuracy of Bedside Chest Ultrasonography (Cus) and Chest Radiography (Cxr) In Assessing Postoperative Complications After Pediatric Heart Surgery. Methods One Hundred and Forty Patients Were Included In Our Analysis. Ibm's Version 25 of the Spss Statistical Analysis Program Was Used. Results Ninetythree Cxrs Were Normal Among a Total of 140. In 47 Chest X-Rays, the Surgeon Saw Anything Out of the Ordinary. Seventy-Two of the Cus Investigations Found Nothing Out of the Ordinary, Whereas 68 Did. Sixty-Nine Trials Had Normal Results from Both Cus and Cxr. Kappa Statistics Revealed a Very High Level of Agreement, With a Kappa Coefficient of K=0.749 (P <0.0001). Cus Has a Sensitivity of 96.9, Specificity of 84.75, Ppv of 73.4, And Npv of 98.43. Conclusion Due to Its Excellent Specificity, Sensitivity, Negative and Positive Predicti ...
