Abstract
During the past few years, cardiac resuscitation has become a well-established procedure. Because the time factor is the most important single element, the percentage of successful revivals has been much higher inside the operating theater than outside. Both cardiac catastrophies to be presented below occurred outside the operating room. Favorable circumstances which permitted immediate treatment made resuscitation of the patient possible each time. Unless effective cardiac action is immediately restored, there are three reasons why it is usually advisable to open the pericardium: (1) proper inspection of the cardiac muscle may be difficult or impossible through the pericardial layer; (2) rhythmical compression of the heart sufficiently strong to maintain a desirable arterial pressure and circulation can rarely be performed with the pericardium intact; (3) any traumatic insult to the heart may produce considerable serous or hemorrhagic intrapericardial effusion, which necessitates an opening for drainage to prevent a tamponade.
