“…Unfortunately, PK data in adult patients on ECMO are sparse. Neonatal and animal studies are available but have shown significant variability and unpredictability of antibiotic PK during ECMO [32,35,46,50,[66][67][68][69][70][71][72][73][74][75][76][77][78][79] (Table 1). However, no dosing guidelines exist for this group of patients.…”

“…Drug metabolism is minimal as approximately 99% of the administered AGs are eliminated unaltered by glomerular filtration in the proximal tubule [34, 35]. The plasma half-life of AGs ranges from 1.5 to 3.5 hours [7, 36], but is prolonged in neonates, infants, and conditions with decreased kidney function [7, 37]. …”

Aminoglycosides are commonly prescribed antibiotics with deleterious side effects to the inner ear. Due to their popular application as a result of their potent antimicrobial activities, many efforts have been undertaken to prevent aminoglycoside ototoxicity. Over the years, understanding of the antimicrobial as well as ototoxic mechanisms of aminoglycosides has increased. These mechanisms are reviewed in regard to established and potential future targets of hair cell protection.

“…The mean gentamicin CL ranged from 0.028 to 0.07 L/hr/kg, the mean half-life ranged from 3.85 to 9.23 hours, and the mean or median central V D ranged from 0.39 to 0.98 L/kg [106–108,112]. In comparison, non-critically ill children had a mean CL of 0.042 L/hr/kg, mean half-life ranging from 2–8 hours, and a mean V D ranging from 0.3–0.43 L/kg [113,114].…”

Developmental and physiological changes in children contribute to variation in drug disposition with age. Additionally, critically ill children suffer from various life-threatening conditions that can lead to pathophysiological alterations that further affect pharmacokinetics (PK). Some factors that can alter PK in this patient population include variability in tissue distribution caused by protein binding changes and fluid shifts, altered drug elimination due to organ dysfunction, and use of medical interventions that can affect drug disposition (e.g., extracorporeal membrane oxygenation and continuous renal replacement therapy). Performing clinical studies in critically ill children is challenging because there is large inter-subject variability in the severity and time course of organ dysfunction; some critical illnesses are rare, which can affect subject enrollment; and critically ill children usually have multiple organ failure, necessitating careful selection of a study design. As a result, drug dosing in critically ill children is often based on extrapolations from adults or non-critically ill children. Dedicated clinical studies in critically ill children are urgently needed to identify optimal dosing of drugs in this population. This review will summarize the effect of critical illness on pediatric PK, the challenges associated with performing studies in this vulnerable subpopulation, and the clinical PK studies performed to date for commonly used drugs.
