OBJECTIVES:
Over 70% of pediatric organ donors are declared deceased by brain death (BD) criteria. Patients with these devastating neurologic injuries often have accompanying multiple organ dysfunction. This study was performed to characterize organ dysfunction in children who met BD criteria and were able to donate their organs compared with those deemed medically ineligible.
DESIGN:
Retrospective cohort study.
SETTING:
PICU at a quaternary care children’s hospital.
PATIENTS:
Patients with International Classification of Diseases, 9th Edition codes corresponding to BD between 2012 and 2018 were included.
MEASUREMENTS AND MAIN RESULTS:
Demographics, comorbidities, Pediatric Risk of Mortality (PRISM)–III, and injury mechanisms were derived from the medical record. Organ dysfunction was quantified by evaluating peak daily organ-specific variables. Fifty-eight patients, from newborn to 22 years old, were included with a median PRISM-III of 34 (interquartile range [IQR], 26–36), and all met criteria for multiple organ dysfunction syndrome (MODS). Thirty-four of 58 BD children (59%) donated at least one organ. Of the donors (not mutually exclusive proportions), 10 of 34 donated lungs, with a peak oxygenation index of 11 (IQR, 8–23); 24 of 34 donated their heart (with peak Vasoactive Inotrope Score 23 [IQR, 18–33]); 31 of 34 donated kidneys, of whom 16 of 31 (52%) had evidence of acute kidney injury; and 28 of 34 patients donated their liver, with peak alanine transferase (ALT) of 104 U/L (IQR, 44–268 U/L) and aspartate aminotransferase (AST) of 165 U/L (IQR, 94–434 U/L). Organ dysfunction was similar between heart and lung donors and respective medically ineligible nondonors. Those deemed medically ineligible to donate their liver had higher peak ALT 1,518 U/L (IQR, 986–1,748 U/L) (p = 0.01) and AST 2,200 U/L (IQR, 1,453–2,405 U/L) (p = 0.01) compared with liver donors.
CONCLUSIONS:
In our single-center experience, all children with BD had MODS, yet more than one-half were still able to donate organs. Future research should further evaluate transplant outcomes of dysfunctional organs prior to standardizing donation eligibility criteria.
