The technique, indications, and results of subxiphoid pericardial window in
penetrating chest wounds with suspected traumatic pericardial tamponade are
reported. The classic signs of pericardial tamponade (elevated central
venous pressure, muffled heart sounds, and paradoxical pulse) are
unreliable in an emergency situation. Chest roentgenograms and
electrocardiograms are of little diagnostic value. Pericardicentesis was
either falsely positive or negative in 50% of our patients. Therefore,
unexplained high central venous pressure and hypotension were considered to
be pericardial tamponade until disproved by the results of a subxiphoid
pericardial window. There were 4 negative and 46 positive findings of
tamponade in 50 consecutive patients with suspected traumatic pericardial
tamponade who underwent creation of a subxiphoid pericardial window. There
were no deaths or complications from the procedures. The early use of
subxiphoid pericardial window has been a major factor in reducing our
mortality rate from penetrating heart wounds to 12% overall, and 8% in the
past three years.
