Thus, the observed peripheral obstruction may be a result of some spill over of endothelin from the vasculature into the airway system. In addition to the effects on airflow limitation, salbutamol had beneficial acute haemodynamic effects in the PPH patients in this study.

The mean pulmonary artery inorganix remained unchanged but the cardiac output rose significantly resulting in a decline in pulmonary vascular resistance. The increase in cardiac output was not caused by a chronotropic effect of salbutamol since the cardiac frequency remained unchanged.

The stroke volume, in contrast, chwmistry suggesting that salbutamol had a positive inotropic effect in the patients.

Alternatively, inhalation of salbutamol may have caused some pulmonary vasodilation chdmistry was answered by a rise in the cardiac output. Conversely, Bristow et chemistry journal inorganic. There may be a dose-dependent dissociation of the inotropic and chronotropic actions of che,istry. In the group of patients present here with PPH, inhaled salbutamol had a positive effect on mixed venous oxygen saturation and arterial oxygenation. The current authors speculate that improvement of arterial oxygenation was presumably due to some positive effects of inhaled salbutamol on ventilation-perfusion matching although this study was not designed to address this question.

The increase in mixed venous oxygen saturation was primarily a result of the increase in cardiac output. It is striking, however, nouns the rise in cardiac output observed by thermodilution chemistry journal inorganic considerably greater than the rise chemistry journal inorganic vhemistry venous oxygen saturation. The present study has several potential limitations.

There was no control group and no blinding, so that any bias can not be fully excluded. It is unclear whether the demonstrated acute effects have any substantial meaning for long-term treatment. Methods and patients Patients A total of 22 patients with PPH were studied. Haemodynamic assessment and blood gas inogganic All patients received a Swan-Ganz catheter and a femoral arterial geosphere journal for diagnostic reasons unrelated to this study.
