Cefoxitin is an antibiotic used in this clinical trial to prevent infections at the site of surgery. The study is comparing two methods of administering this medication to see which is more effective in preventing infections after colorectal surgery. One method involves giving a loading dose followed by a continuous infusion, while the other method uses standard intermittent doses. The goal is to find out if the continuous infusion method is better at reducing infections within 30 days after surgery.

Surgical Site Infection (SSI) – This condition occurs when bacteria infect the area of the body where surgery was performed. SSIs can be superficial, affecting only the skin, or more severe, involving tissues under the skin, organs, or implanted material. Symptoms may include redness, pain, and swelling at the surgical site, along with fever and drainage of cloudy fluid. The infection typically develops within 30 days after surgery. SSIs can lead to complications such as delayed healing and may require additional medical interventions. The risk of developing an SSI can vary based on the type of surgery and the patient’s overall health.

Anastomotic Leak – This condition occurs when there is a breakdown or failure at the surgical connection between two parts of the intestine. It can lead to the leakage of intestinal contents into the abdominal cavity, causing inflammation and infection. Symptoms may include abdominal pain, fever, and changes in bowel habits. The leak typically occurs within a few days to weeks after surgery. It can result in the need for further surgical intervention to repair the leak. The condition can complicate recovery and prolong hospital stays.

Clostridium difficile Infection – This infection is caused by the bacterium Clostridium difficile, which can lead to inflammation of the colon. It often occurs after the use of antibiotics, which disrupt the normal balance of bacteria in the gut. Symptoms include diarrhea, abdominal pain, and fever. The infection can range from mild to severe and may lead to complications such as dehydration. It is commonly acquired in healthcare settings, particularly among patients receiving prolonged antibiotic treatment. The infection can be recurrent, requiring multiple treatments to resolve.
