Skill Station E ADJUNCTS LEARNING OBJECTIVES 1. Identify the appropriate positioning of an ultrasound probe for FAST and eFAST exams. 2. Identify fluid on still images or video of FAST exam. 3. Identify ultrasound evidence of pneumothorax on video images of an eFAST exam. 4. Use a structured approach to interpret a chest x-ray and identify injuries present (see Skill Station B: Breathing). 5. Explain the value of the anteroposterior (AP) pelvic x-ray examination to identify the potential for massive blood loss, and describe the maneuvers that can be used to reduce pelvic volume and control bleeding. 6. Use a structured approach to interpreting a plain x-ray of the spine or CT (based on course director’s preference). 7. Use a structured approach to evaluating a pelvic x-ray. Skills Included in this Skill Station •• Perform a FAST Exam and Properly Position Probes •• Perform an eFAST Exam and Properly Position Probes •• Identify Abnormal eFAST on Still or Video Images •• Identify Fluid on FAST Video or Still Images of FAST •• Evaluate Thoracic and Lumbar Spine Images •• Interpret a Pelvic X-Ray Perform a FAst Exam and pRoperly Position Probes STEP 1. Use a low-frequency probe (3.5 mHz). Start with the heart to ensure the gain is set appropriately. Fluid within the heart will appear black. Place the probe in the subxyoid space, with the probe marker to n FIGURE G-1 the right (n FIGURE G-1). The probe angle is shallow, and the liver is used as an acoustic window. STEP 2. Move to the right upper quadrant view. Place the probe marker toward the head in the coronal plane in the anterior axillary line (n FIGURE G-2). Rotate the probe obliquely and scan from cephalad to caudad to visualize the diaphragm, liver, and kidney. n BACK TO TABLE OF CONTENTS 365

Begin scan more cephalad than on the right and more posterior. Begin in the midaxillary line. Rotate the probe obliquely and visualize the diaphragm, spleen, and kidney. STEP 4: (Ideally, the bladder is full.) Place the probe above the pubic bone with the probe marker pointing to the right (n FIGURE G-4). Scan for fluid, which appears as a dark stripe. Rotate the probe 90 degrees so the probe marker points to the head (n FIGURE G-5). Scan for fluid. Perform an eFAst exam ANd DemonstRAte Proper pRobe Positioning STEP 1. Place the probe in the second or third intercostal space in the mid clavicular line in n FIGURE G-5 a sagittal orientation (n FIGURE G-6), and slide the probe caudally (n FIGURE G-7). Examine 2 or 3 interspaces. Including more interspaces increases the sensitivity STEP 2. Evaluate the right and left diaphragms using the same probe position as for evaluation of the perihepatic and perisplenic space (n FIGURE G-8), sliding the probe one rib space cephalad (n FIGURE G-9). STEP 1. Identify Abnormal eFAst on Still or Video Images Look for lung sliding. If you see none, look for lung pulse. STEP 2. Look for comet tails. STEP 3. Look for seashore, bar code, or stratosphere sign in M mode. Bar code and stratosphere signs indicate pneumothorax. n BACK TO TABLE OF CONTENTS
