Tamponade a rare cause of shock in patients with pancreatitis: difficulty of diagnostic in patients with positive pressure ventilation.

The causes of hemodynamic instability in acute pancreatitis are numerous. Although pericardial effusion during pancreatitis is common, a cardiac tamponade is rarely reported. The diagnosis of compressive cardiac disorders (CDD) by echocardiography is easily reported when the patient is breathing spontaneously; it becomes difficult when the patient is assisted with positive pressure ventilation.
