EFAST thoracic views are an essential component of the Extended Focused Assessment with Sonography for Trauma (EFAST) exam, specifically evaluating the chest for life-threatening conditions in trauma patients. These ultrasound views primarily aim to detect pneumothorax (collapsed lung) and hemothorax (blood in the chest cavity), which can rapidly compromise respiratory and circulatory function. The EFAST protocol expands upon the traditional FAST exam, incorporating lung and pleural assessments to provide a more comprehensive and immediate bedside evaluation.
Utilizing medical ultrasound, EFAST thoracic views typically involve scanning the anterior and lateral chest walls to visualize the pleural line for “lung sliding” – a key indicator of a healthy pleura. The absence of lung sliding, coupled with the presence of a “barcode sign” on M-mode, is highly suggestive of pneumothorax. Timely and accurate identification of these conditions through EFAST thoracic views is crucial for guiding emergent interventions and improving patient outcomes in critical care settings.
