However, both groups
frequently had elevated trough concentrations >2 mg/L when receiving gentamicin 4-5 mg/
kg every 24 hours (44% of normothermic and 36% of hypothermic).This highlights the
need for a potential alternative dosing of gentamicin in the neonate with HIE. Given that
hypothermia is now recommended as the standard of care for moderate to severe HIE, an
understanding of gentamicin pharmacokinetics in the clinical context of hypothermia will be
necessary to help guide dose selection in this population. The objectives of this study were
1) to evaluate the pharmacokinetics of gentamicin in neonates with HIE receiving
hypothermia using a population-based approach and 2) to identify an empiric gentamicin
dosing strategy that optimizes achievement of target peak and trough drug concentrations.
