Abstract
An apparently rare case of acute hemorrhagic necrosis of the intestine due solely to acute circulatory insufficiency, without complicating cardiovascular disease, dceloped in a 27-yr.-old woman. Following restoration of the circulation by transfusions, a somewhat different type of shock persisted, characterized by high cardiac output, low peripheral resistance, and anuria. After removal of the infarcted bowel, shock with low cardiac output was evident; this responded to isoproterenol infusion. High output, low resistance shock is common in our series of shock patients and is frequently accompanied by anuria. This hemodynamic state may in part be due to the release of vasoactive substances from functionally, but perhaps not visibly, damaged bowel.
