The presence and severity of postoperative pericardial effusions were studied echocardiographically in 114 consecutive patients (70 males, 44 females; mean age 56 +/- 10 years). An effusion was present in 35 patients at 3-5 days. An effusion was less common when a drainage tube was inserted for 24-36 h in the posterior as well as the anterior mediastinum than when only an anterior drain was used. Patients with effusions differed from those without in having more supraventricular arrhythmias, more wound infections, smaller total blood drainage and longer postoperative hospital stay. Three patients with posterior pericardial effusions developed cardiac tamponade 5-18 days postoperatively. The data show that pericardial effusions are associated with postoperative complications and suggest that effusion formation can be reduced by using posterior as well as anterior chest drains.
