This difference was most prominent after pulmonary vasodilation with oxygen inhalation.
There is also an increase in sympathetic versus parasympathetic activity9 which predisposes to a greater degree of peripheral vasodilation.
Intracardial injections with 1 ml of 1% sodium nitrite and 1000 units of sodium heparin were made to reduce coagulation and increase vasodilation.
Management of this condition is difficult and various vasodilators have been unsuccessful in providing preferential pulmonary vasodilation.
In the acute early phase there is vasodilation with the classical, full, bounding pulsation and arterial bruit.
Our study has shown that it is combined administration of nitric oxide and beraprost which 30 produces maximal pulmonary vasodilation.
The management of this condition is difficult and different types of vasodilators have not succeeded in producing preferential pulmonary vasodilation.
Accordingly, the selectivity of pulmonary vasodilation may be overestimated in the setting of loading with nitric oxide.
