Key result
Targeted single-dose antibiotic prophylaxis at anesthesia induction minimizes surgical infections for procedures under four hours.
Why the study?
Inappropriate use of antibiotics for surgical prophylaxis increases cost and promotes antibiotic resistance, highlighting the need for appropriate selection and timing.
Does surgical antibiotic prophylaxis prevent infections at the surgical site in patients undergoing contaminated or device-insertion surgery?
Does surgical antibiotic prophylaxis prevent infections at the surgical site in patients undergoing contaminated or device-insertion surgery?
Appropriate use of surgical antibiotic prophylaxis, typically a single dose at induction, is standard of care to prevent surgical site infections while minimizing antibiotic resistance.

Reduces surgical site infection risk while limiting resistance; leaves open optimal regimens for specific high-risk procedures.
Surgical antibiotic prophylaxis is defined as the use of antibiotics to prevent infections at the surgical site.Prophylaxis has become the standard of care for contaminated and cleancontaminated surgery and for surgery involving insertion of artificial devices.The antibiotic selected should only cover the likely pathogens.It should be given at the correct time.For most parenteral antibiotics this is usually on induction of anaesthesia.A single dose of antibiotic is usually sufficient if the duration of surgery is four hours or less.Inappropriate use of antibiotics for surgical prophylaxis increases both cost and the selective pressure favouring the emergence of resistant bacteria.

Wendy Munckhof (2005) conducted a review in Surgical site infections. Surgical antibiotic prophylaxis was evaluated. Surgical antibiotic prophylaxis should target likely pathogens and be given at the correct time, typically as a single dose on induction of anaesthesia for surgeries lasting four hours or less.
