Appropriate use of antimicrobial agents for surgical prophylaxis has been shown to reduce the incidence of postoperative infection for a variety of surgical procedures. This is important because:
-
global emergence of antimicrobial resistance (due to the force of selection from over use of antibiotics)
-
transition to managed care requiring both cost containment and quality assurance
Standard guidelines recommend that prophylaxis is indicated only for clean-contaminated and specific clean surgical procedures where the benefits in preventing a rare infection exceed the risks and costs of prophylaxis. However, compliance with the guidelines is poor.
Antibiotic prophylaxis must be started in close proximity to the time of the surgical procedure in order to achieve effective tissue concentrations at the time of incision and throughout the operation. The major exception is cesarean section, in which the first dose of prophylaxis should be delayed until the umbilical cord is clamped to avoid placental transfer of the antibiotic to the fetus.
Selection of an antibiotic should consider spectrum of activity and cost-effectiveness. A single dose of antibiotic before the operation is sufficient prophylaxis for most surgical procedures. Theoretically, for longer procedures, re-administration of the drug is indicated at intervals of 1 or 2 times the half-life of the drug. No further benefit is conferred by the administration of additional doses after the patient has left the operating room.
