Bedside hemodynamic monitoring. Its value in the diagnosis of tamponade complicating cardiac surgery.
Cardiac tamponade may be a difficult clinical diagnosis in the early postoperative period in patients undergoing open-hear surgery, particularly when the anterior or lateral pericardium is left open. Bedside monitoring of intracardiac pressures and determination of a "pressure plateau" between right atrial, right ventricular diastolic, pulmonary arterial diastolic, and pulmonary capillary wedge pressures are useful in the early diagnosis of cardiac tamponade. The value of such hemodynamic monitoring in the  diagnosis and treatment of cardiac tamponade in three patients with aorta-coronary artery bypass surgery in the early postoperative period is reported. Appropriate therapy, carried out on the basis of these studies, minimized the occurrence of further morbidity or possible death.
