ABSTRACT
The selective hemodynamic effects of an intravenous infusion of prostacyclin on skin and on forearm blood flow during inceasing doses up to 6 ng.kg. -1min.-1 were evaluated in 12 healthy volunteers. The highest dose raised total skin blood flow (p=0.0001) as measured by laser Doppler with a concomitant rise in finger skin temperature (p=0.02). Capillary perfusion as measured by transcutaneous oxygen monitoring remained relatively unaffected (p=0.25). Cold-induced vasoconstriction and the recovery thereafter were not influenced. Diastolic blood pressure tended to decrease (p=0.06), but there was no change in systolic blood pressure, forearm blood flow, and calculated forearm vascular resistance. The authors conclude that prostacyclin may have dissimilar vasoactive potencies in different vascular beds as shown by pronounced increase in total skin blood flow, owing to vasodilation of shunt vessels, simultaneously with an insignificant change in nutritional skin blood flow and forearm muscle blood flow.

    Background: Carbon dioxide (CO2) pneumoperitoneum (PP) increases mean arterial blood pressure (MAP) and systemic vascular resistance (SVR) but decreases stroke volume (SV) and cardiac output (CO). This study evaluated the hemodynamic effects of elevated intraab-dominal pressure (TAP) occurring...

    This study examined the integrative changes of blood pressure (BP) and stroke volume (SV) leading to the initial biphasic heart rate (fc) response (first 15 s) in simulated diving manoeuvres with and without breathholding (BH). Simulated diving was studied in ten young healthy volunteers by...

    In patients suffering from primary pulmonary hypertension (PPH), a raised pulmonary vascular resistance may limit the ability to increase pulmonary blood flow as work rate increases. We hypothesised that oxygen uptake (VO2) may not rise appropriately with increasing work rate during incremental...

    Barnidipine is a stereoselective single isomer formulation of a long-term acting dihydropyridine calcium antagonist (CaA). In anaesthetised animals, the antihypertensive response to barnidipine is accompanied by a diuretic effect. The aim of the present study was to examine whether barnidipine...

    Nitric oxide (NO) plays an important role for the pulmonary circulation in normal and chronic hypoxia. We examined effects of endogenous nitric oxide synthase (NOS) inhibition on pulmonary and systemic vascular resistance in unanesthetized pigs living at three levels of altitude to evaluate the...
