CHANGES IN POSTOPERATIVE COLLOID ONCOTIC PRESSURES AFTER OPEN HEART SURGERY ESPECIALLY IN RELATION TO RECOVERY OF THE HEMODYNAMIC AND RESPIRATORY STATUS
In order to evaluate the relationship among the changes of colloid oncotic pressure (COP), hemodynamic and respiratory recovery after open heart surgery, cardiac index (CI), pulmoanry capillary wedge pressure (PCWP), (A-a) DO
2, urine output and COP were measured in 33 patients during 48 hours after the cardio-pulmonary bypass (CPB). The patients were divided into three groups according to COP vaiues at 3 and 24 hours after CPB. Twenty three patients whose COP values were normal (COP≧ 19mmHg) at 3 hours after CPB maintained stable hemodynamic and respiratory status. Cardio respiratory status were deteriorated in the 6 patients whose COP values were below normal both 3 and 24 hours after CPB. On the other hand, 4 patients with normal (A-a) DO
2 and low COP values at 3 hours after CPB demonstrated rapid recovery of COP values and improvement of cardiac function. It is concluded that the patients with both cardiac and respiratory dysfunction have low COP values during 48 hours after CPB, but the patients with normal (A-a) DO
2 and low COP at 3 hours after CPB demonstrate the recovery of COP values with rapid improvement of cardiac function until 24 hours after open heart surgery.
