Massive hepatic hemorrhage associated with cardiopulmonary resuscitation.

We treated two patients with laceration of the liver that was precipitated by cardiopulmonary resuscitation (CPR) and recognized antemortem. Both patients had myocardial infarctions and had received heparin sodium therapy. They had excruciating abdominal pain and bled massively, resulting in hypovolemic shock. When severe abdominal pain associated with hypovolemic shock occurs in a patient who has received CPR, hepatic laceration, hematoma, or both should be considered. This is even more imperative to recognize in the patient who has received anticoagulation therapy.
