  • Title: Unwillingness to lie supine? a sign of pericardial tamponade.
    Author: Porter JM, Ivatury RR.
    Journal: Am Surg; 1997 Apr; 63(4):365-6. PubMed ID: 9124761.
    Abstract:
    The stable patient with an occult cardiac injury can represent a diagnostic dilemma. The trauma surgeon must maintain a high index of suspicion for cardiac injury with precordial penetrating trauma. Herein are reported two cases of stable patients with penetrating precordial trauma who refused to lie supine because of difficulty breathing, preferring to sit upright, who eventually had positive pericardial windows and sternotomies for repair of cardiac injuries. The presence of this clinical finding, unwillingness to lie supine, should make the trauma surgeon highly suspicious of a cardiac injury and to proceed quickly to echocardiography or, preferably, to subxiphoid pericardial window to rule out cardiac injury.
