Comparison of a Morphomic-Based to the Standard-of-Care-Based Cefazolin Dose for Antimicrobial Prophylaxis

Description

The goal of this clinical study is to compare the dosing of an antibiotic in overweight patients having surgery. The main question\[s\] it aims to answer are: * Are the antibiotic concentrations in blood and fat tissue in patients that are overweight sufficient to prevent the chance of infection? * Can dosing using body composition rather than body weight improve the chance of achieving good antibiotic concentrations in overweight patients? Participants will allow us to collect small amounts of blood and fat tissue during their regularly scheduled surgery. Researchers will compare differences in antibiotic concentrations based on dosing by standard of care (body weight based) versus body composition.
