On the pericardial view, look for a black stripe of fluid separating the hyperechoic pericardium from the gray myocardium. This stripe represents fluid. STEP 2. Look at the hepatorenal space. Intraperitoneal fluid has a black hypoechoic or anechoic appearance. STEP 3. Look at the splenorenal space. Blood will appear as a hypoechoic or anechoic strip in this area. STEP 4. Look around the bladder for an area of hypoechogenicity. STEP 5. Be sure you have thoroughly visualized all spaces before declaring an examination negative. Evaluate Thoracic and LumbAR Spine Images (optional) Note: Before interpreting the x-ray, confirm the patient name and date of examination. STEP 1. Assess for alignment of vertebral bodies/ angulation of spine. STEP 2. Assess the contour of the vertebral bodies. STEP 3. Assess the disk spaces. STEP 4. Assess for encroachment of vertebral body on the canal. Interpret a Pelvic X-Ray Note: Before interpreting the x-ray, confirm the patient name and date of examination. STEP 1. Check for interruption of the arcuate and ilioischial lines, including the pubic symphysis. The pubic symphysis should be n BACK TO TABLE OF CONTENTS

Check the transverse processes of L-5 because they may fracture with sacroiliac disruption. STEP 3. Check the sacrum for evidence of fracture. The arcs of the foramina may be interrupted with sacral fractures. Links to Future LeARNing Post ATLS—Review the FAST performance video on the MyATLS mobile app. After this course, take the opportunity to perform FAST and eFAST on your patients to improve your comfort with use of this technology. In addition, make an effort to read pelvic x rays on your own before looking at the radiologist interpretation. STEP 4. Check the acetabulum bilaterally for interruption and femoral dislocation. Check the femoral head and neck for disruption bilaterally. n BACK TO TABLE OF CONTENTS
