Plasma catecholamine levels and pulmonary dysfunction in sepsis.
In a retrospective analysis of 18 patients with sepsis and adult respiratory distress syndrome, we found that high plasma epinephrine and noradrenalin levels were associated with severe defects in oxygenation that accompany this disease. The result of previous experimental work support the concept that high plasma catecholamine levels augment already existing defects in the ventilation to perfusion ratio and increases the measured intrapulmonary shunt fraction. The results of this study do not, however, delineate whether or not the relationship between high circulating plasma catecholamine levels and severe adult respiratory distress syndrome is causal or simply a measurement of two indexes which reflect the severity of the underlying disease process.
