Vancomycin pharmacokinetics in patients with severe burn injuries

Burns · 10.1016/j.burns.2009.08.010

Structure

A two-compartment model, driven by weight, creatinine clearance and burns.

Study population

Burn and Mixed patients — Australia. Fitted to 70 patients and 214 concentration observations.

Covariate As reported
Age 53 (15–95) yr
Weight 68 (42.5–116) kg
CrCl 100.5 ± 54 mL/min

Reported as the source publication gives them — mean ± SD, or median with range or interquartile range.

CL = 4.7 \cdot \frac{CrCl \cdot \frac{60}{1000}}{6.53}
V_1 = 68.4 \cdot \frac{Weight}{70} + 33.1 \cdot Burn
V_2 = 73.0 \cdot \frac{Weight}{70}
Q = 4.54

Implementation notes

Burns/controls cohort; lean body weight for CrCl. Burn (from tag) adds 33.1 L to central volume; BOV excluded.
