Propofol pharmacokinetics were examined in 17 adults with major burns during the hyperdynamic convalescent phase. Eighteen nonburned surgical patients served as controls. After a 2-mg/kg intravenous dose of propofol, blood samples were collected at multiple time points. Noncompartmental methods were used to calculate the pharmacokinetic parameters. The following indices were higher in burns than controls: propofol clearance (64+/-17 vs 29+/-4 mL/kg/min, P<.001) and volume of distribution (8+/-3 vs 4+/-1 L/kg, P<.001). The area under the curve was smaller in burns (556+/-152 vs 1193+/-183 microg/mL h, P<.001). The higher clearance of propofol in burned patients may imply that these patients require higher doses or infusion rates of propofol to attain a target plasma concentration or pharmacodynamic effect.
