Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The risk of surgical site infections are higher in patients with obesity compared to non-obese adults. Our group has previously demonstrated that radiologic measures of abdominal subcutaneous fat are associated with surgical site infection risk in patients undergoing colorectal surgeries, which could reflect suboptimal antibiotic exposure in these patients. Therefore, we hypothesized that measures of abdominal size and composition in patients undergoing colorectal surgery would be more predictive of antimicrobial pharmacokinetics in this tissue compartment than the current standards of body weight and BMI. We confirmed this hypothesis and identified kidney function and body depth (by morphomics) to be predictive of cefazolin exposure in target tissue. Morphomics is a technology that transforms existing computed tomography data into body measures and composition. This study is a head-to-head comparison of this new proposed morphomic test regimen to the standard of care.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The current model for dosing the drug cefazolin includes the selection of 2 grams if the individual weighs less than 120 kg and 3 grams if they weigh 120 kg or more. The morphomic-based model defined the choice of 2 grams versus 3 grams of cefazolin based on kidney function and body depth.
