Current opinion in anaesthesiology
-
Toxicity concerns and awareness during anesthesia issues continue to concern pediatric anesthesiologists. Most developmental pharmacokinetic, pharmacodynamic and pharmacogenomic changes occur within the first year of life. Understanding these early changes can improve drug use in this cohort. ⋯ Mechanistic models create a framework for the study of pharmacokinetic changes in infancy. Understanding these changes allows a target concentration approach to therapy and potential for reduced toxicity. The target concentration may be undefined because of a paucity of effect measures.
