Antibiotic prophylaxis
Antibiotic prophylaxis refers to the prevention of infection complications using antimicrobial therapy (most commonly antibiotics).
Even when sterile techniques are adhered to, surgical procedures can introduce bacteria and other microbes in the blood (causing bacteremia), which can colonize and infect different parts of the body. An estimated 5 to 10 percent of hospitalized patients undergoing otolaryngology ("head and neck") surgery acquire a nosocomial ("hospital") infection, which adds a substantial cost and an average of 4 extra days to the hospital stay.
Antibiotics can be effective in reducing the occurrence of such infections. Patients should be selected for prophylaxis if the medical condition or the surgical procedure is associated with a considerable risk of infection or if a postoperative infection would pose a serious hazard to the patient's recovery and well-being.()
==Microbial infections==
Local wound infections (superficial or deep-sided), urinary tract infections (caused by bladder catheter, inserted for surgery), and pneumonia (due to impaired breathing/coughing, caused by sedation and analgesics during the first few hours of recovery) may endanger the health of patients after surgery. Visibly worse are postoperative bacterial infections at the site of implanted foreign bodies (sutures, ostheosynthetic material, joint replacements, pacemaker implants, etc.) Often, the outcome of the procedure in question and even the life of the patient is at risk.
