Duration of treatment in the dataset had a median of 34 days and ranged from 3 to days. In obese individuals, it is suggested that aminoglycosides incompletely distribute into the super obese girls adipose mass, and cosing adjusted body weight is commonly used to account for this. Furthermore, several patients would have received lower doses, resulting in a significant reduction in the proportion of unnecessarily high concentrations and a lower cost.

It's probably preferable to dose vancomycin based on individual patient pharmacokinetics as explored here. There are a lack of pharmacokinetic data on the use of commonly used drugs in obese children, therefore knowledge of which size descriptor to use in determining the optimum dose for this group of patients is limited.

Actively transported into neutrophils and macrophages, causing concentration in abscesses. ESBL refers to plasmids which confer resistance to most beta-lactams, except for cephamycins cefoxitin, cefotetan, and cefmetazole and carbapenems. The extent of these changes is variable and depends upon both patient —specific factors and the physico-chemical properties of the drug. Normally this gene is suppressed, so it may be undetectable in laboratory tests.
