Abstract:
We evaluated the effects of fluid challenges on oxygen delivery (DO2) and oxygen consumption (VO2) in nine patients receiving immunotherapy with interleukin-2. Fluid resuscitation produced an increase in DO2 from 15.7 +/- 3.1 to 17.4 +/- 3.5 ml/min/kg (mean +/- SD, p less than 0.001), which was associated with a corresponding increase in VO2, from 2.8 +/- 0.7 to 3.1 +/- 0.6 ml/min/kg (p less than 0.01). These results suggest that oxygen consumption may be dependent on oxygen delivery in patients on IL-2 therapy. The presence of oxygen supply dependency may contribute to the multiple organ failure observed with IL-2 administration.
