Palpation – Tenderness in injured area – Crepitus may be felt – Abnormal movement of chest wall may be palpable Percussion – Hyper-resonance (if pneumothorax present) – Dull (if hemothorax, pulmonary contusion present) Auscultation – Air entry reduced in injured area – Crackles may be present DIFFERENTIAL DIAGNOSIS – Chest wall contusion – Simple rib fractures COMPLICATIONS – – – – – – – – Poor ventilation Hypoxia Hypovolemia Pneumothorax Hemothorax Pulmonary contusion Myocardial contusion Cardiac tamponade
Percussion – Hypersonorité (s’il y a un pneumothorax) – Bruit sourd (s’il y a un hémothorax ou des contusions pulmonaires) Auscultation – Entrée d’air réduite dans la région atteinte – Il peut y avoir des crépitations. DIAGNOSTIC DIFFÉRENTIEL – Contusions de la paroi thoracique – Fractures fermées aux côtes COMPLICATIONS – – – – – – – – Ventilation insuffisante Hypoxie Hypovolémie Pneumothorax Hémothorax Contusions pulmonaires Contusions myocardiques Tamponnade cardiaque
