The utilization of cardiopulmonary bypass systems, for circulatory and/or pulmonary support of patients undergoing non-cardiac procedures, has been previously reported. There is, however, a sub-group of patients for whom total systemic anticoagulation for cardiopulmonary support is extremely undesirable or contraindicated altogether, due to the presenting pathology or procedure to be performed. Clinical and experimental reports have suggested that with the use of heparin-bonded bypass circuits, the amount of heparin required for anticoagulation of the patient may be substantially reduced, or eliminated, safely. This allows the resuscitation and/or support of patients in whom bypass would otherwise be contraindicated. We present our clinical experience with heparin-bonded, biocompatible circuits, for support of patients undergoing non-cardiac procedures. In each case, low-dose or no heparin was administered. The group includes patients with trauma related pulmonary insufficiency, pulmonary embolism, hypothermia, neurosurgery, aortic aneurysm, aortic transection, respiratory distress syndrome, pericardiectomy, and cardiogenic shock.
