Cardiopulmonary function following post-cardiac surgical mediastinitis.
Eleven survivors of bacterial mediastinitis, which followed cardiac surgery through a median sternotomy approach, underwent noninvasive cardiopulmonary evaluation to determine whether clinically apparent mediastinal fibrosis had developed. Compared to preoperative values, forced vital capacity was reduced by 9.75 percent of predicted; the greatest reduction occurred in those patients with Gram-negative mediastinitis. In one patient, an abnormal jugular venous wave form and apex cardiogram were consistent with constrictive cardiac physiology, but this was not associated with an abnormal echocardiogram or impaired functional status. In this small series, no serious abnormalities in cardiopulmonary function were detected which could be attributed to prior mediastinal infection.
