Early postoperative changes with different priming solutions in open-heart surgery.

The consequences of substituting dextran 70 (Macrodex) for human plasma in the priming solution were studied during the first 48 hours after open-heart surgery. Twenty patients undergoing elective surgery for coronary artery disease were selected for the study. Clinical, haemodynamic, metabolic and roentgenologic parameters were monitored. No major differences were found between results with use of plasma or dextran (each in 10 patients). The lower pulmonary capillary wedge pressure in the dextran group may indicate better left ventricular performance. As human plasma is a limited resource and is a potential disease transmitter, dextran 70 may with advantage replace human plasma in the priming solution, and at much lower cost.

Should the lungs be ventilated during cardiopulmonary bypass? Clinical, hemodynamic, and metabolic changes in patients undergoing elective coronary artery surgery.

No beneficial effects were achieved by ventilating the lungs of a group of 10 patients during total extracorporeal circulation for coronary artery bypass operation. Ventilation of nonperfused lungs, which was suggested to prevent postoperative atelectasis, may even have negative effects. Intrapulmonary shunting increased significantly (p less than 0.05), while the shunt fraction in the nonventilated lungs of another group of 10 patients remained unchanged. There were only minor differences between the two groups with respect to systemic and pulmonary hemodynamic changes.
