Ultrasound is highly sensitive for ruling out a pneumothorax in supine patients by identifying lung sliding, a to-and-fro movement along an echogenic line observed when the visceral pleura slides on the parietal pleura during respiration (Fig. 1) [1-4]. However, concern exists that the presence of pulmonary contusions may affect lung sliding and limit the usefulness of ultrasound to exclude a pneumothorax under these circumstances [3]. We sought to investigate in a pilot study the potential influence of pulmonary contusions on lung sliding.
