[Disturbances of ventilatory distribution as a cause of postoperative hypoxemia after cardio-thoracic surgery (author's transl)].

In a group of 21 patients with thoracotomy the lung function was investigated pre-and postoperatively with particular consideration to N2-clearance. From the N2-clearance an Inspiratory Gas Distribution Index (IDI) is derived. This Index allows in combination with blood gas analysis an interpretation of ventilatory disturbances in the lung.

[Reversibility or irreversibility of pulmonary function changes after cardiac surgery on insufficient or stenotic cardiac valves (author's transl)].

In 69 patients with mitral- or aortic valves disease lung function tests were made preoperatively and 2 to 4 years after cardiac surgery. We wanted to demonstrate the extent and the improvement of restriction, obstruction and disturbed diffusing capacity of the separate diseases with different severities. We found correlations between the clinical grade of the disease and the changes in lung function. In particular grade III of the mitral stenosis showed severe restriction, obstruction and disturbed diffusing capacity. Patients with mitral insufficiency III had changes of mild degree, aortic diseases were without disturbed lung function. All detected changes of lung function were irreversible and could not be influenced by postoperative hemodynamic improvements.

Clinical comparison between membrane and bubble oxygenators in cardiopulmonary bypass.

The clinical course of two similar patient groups was compared in whom, during cardiopulmonary bypass, a membrane or bubble oxygenator was employed. According to our results there is no significant functional difference between the two types of oxygenators as long as the perfusion time does not exceed 90 minutes. Beyond this time limit, the membrane oxygenator has distinct advantages, particularly with regard to hemolysis. We presently prefer the bubble oxygenator. The use of a membrane oxygenator is restricted to complex open heart procedures with suspected technical problems.
