Pharmacokinetics and pharmacodynamics of propofol in children undergoing different types of surgeries

The BIS values in children are highly correlated with the propofol effect compartment concentrations according to the classical Emax concentration-response relationship. Children had slightly lower sensitivity to propofol and slightly higher clearance, as compared with the adult data available in literature. The intra-patient variations in the BIS require the anesthesiologist's attention in using BIS values alone to evaluate the depth of anesthesia in children.
