Overview

The goal of this prospective, multicentre, double-blind, randomized clinical trial is to compare intermittent cefoxitin administration to loading bolus followed by continuous infusion for surgical antibiotic prophylaxis in colorectal surgery.

The main objective is to demonstrate the superiority of a loading dose of cefoxitin followed by continuous infusion over standard of care boluses in reducing SSI within 30 days after colorectal surgery
