Abstract
The systolic, diastolic, and the mean arterial systemic blood pressure decreased after thoracotomy (by -12%). The systolic, diastolic, and the mean pulmonary arterial pressure showed an immediate decrease (by 25%). The central venous pressure was not changed. The cardiac output (HMV) and the stroke volume could not be measured before the thoracotomy. However, the HMV (+17%), the HMV-index (+30%), and the stroke volume (+60%) increased from the 10th to the 30th min after the thoracotomy. The heart rate decreased continuously (by -19%). The maximum rate of pressure rise (dp/dtmax) increased primarily insignificantly and decreased afterwards (by -10%). The quotient dp/dt/p decreased immediately (by -10%). All measures were carried out until the 30th min after thoracotomy.
