Abstract
Because respiratory dysfunction after hematopoietic stem cell transplantation is a manifestation of a continuum of dysfunction temporarily induced by the transplant process, a proactive rather than reactive approach might prevent or attenuate its progression to acute respiratory distress syndrome. Organ dysfunction in this population results from cytokine-driven processes, of which the first manifestation includes fluid accumulation. We describe a multistep protocol that first targets fluid balance control, both through restriction of intake and through augmentation of output using dopamine and furosemide infusions. If these steps fail to stem the tide of water accumulation, we advocate the relatively early use of continuous renal replacement therapy, its use triggered by a continued increase in body weight (>10% above baseline), an increasing c-reactive protein level, and an increasing oxygen need. Renal function parameters do not figure in this protocol. We recommend continuous renal replacement therapy at 35 mL/kg/h (2,000 mL/1.73 m(2)/h), a dose that allows adequate flexibility in fluid management and that may provide effective clearance of proinflammatory (and anti-inflammatory) mediators that drive the evolving dysfunction. Proactive intervention improves the clinical status such that the transition to mechanical ventilation may proceed smoothly or in some cases even may be avoided altogether.
