What is the role of antibiotics post-surgery?

The primary role of antibiotics post-surgery is to prevent infection. When a surgical procedure is performed, especially those that involve incisions or manipulation of tissues, there is a risk of introducing bacteria that can lead to surgical site infections. Antibiotics help reduce this risk by either killing the bacteria or inhibiting their growth. Administering antibiotics prophylactically, before and after surgery, is a common practice to ensure that any potential pathogens present in the body do not lead to infection during the healing process. This is particularly important in high-risk procedures or in patients with weakened immune systems, where the likelihood of infection is greater.

While preventing pain, promoting digestion, and enhancing healing are important aspects of post-surgical care, they are addressed through other means such as pain management strategies, nutritional support, and overall patient care practices. However, the specific role of antibiotics directly ties to infection control, making prevention of infection their primary function.
