Mechanically ventilated pediatric stem cell transplant recipients: effect of cord blood transplant and organ dysfunction on outcome.
OBJECTIVES: To compare survival of pediatric umbilical cord blood and bone marrow transplant recipients requiring admission to a pediatric intensive care unit for mechanical ventilation and to determine the effect of organ dysfunction on outcome. DESIGN: Retrospective chart review. SETTING: Tertiary care referral center for pediatric stem cell transplants. PATIENTS: All children 0-18 yrs old admitted to the pediatric intensive care unit for mechanical ventilation after receiving a stem cell transplant. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Data were collected from medical records of 86 patients who received a stem cell transplant and were subsequently admitted to the pediatric intensive care unit for mechanical ventilation. Demographic data were collected at the time of intubation, and physiologic data were collected at 6 hrs and 96 hrs after intubation. The pediatric intensive care unit, hospital, and 2-yr survival rates for umbilical cord blood transplant recipients were 37%, 25%, and 19%, respectively. The survival rates for bone marrow transplant recipients were 47%, 32%, and 21% for the same time periods. Umbilical cord blood and bone marrow transplant recipients with hepatic dysfunction had a significantly worse outcome, as did patients admitted for respiratory failure or sepsis. CONCLUSIONS: Pediatric recipients of an umbilical cord blood transplant who subsequently required mechanical ventilation had lower pediatric intensive care unit and hospital survival rates compared with patients receiving bone marrow transplantation. Survival at 2 yrs for umbilical cord blood transplant and bone marrow transplant patients was similar. Predictors of outcome for all stem cell transplant recipients requiring mechanical ventilation included pediatric intensive care unit diagnosis requiring intubation and hepatic function. Predictors of outcome can be identified shortly after intubation in pediatric stem cell transplant recipients and may aid in therapeutic decision making and family counseling.
