Examples of Class III surgical procedures include, but are not limited to:appendicectomyin acute appendicitisopening of biliary tractin acute cholecystitisincision and drainage of abscessgun shot wound (fresh, without perforated bowel)rectal surgeryTUR or suprapubic prostatectomywith positive pre-op urine culture.vaginal or cesarean sectiondeliveries with PROM 24 hours.Placement : patients in this category may be placed together. Prevention : mechanical cleaning, washing, antibiotic therapyclass IV : dirty surgery: existing acute bacterial infection or a perforated viscera is encountered (clean tissue is transected to gain access to pus= higher bacterial load).traumatic wound-old(4 < hours < 24) with retained devitalized tissuefecal contamination, foreign body or retained, devitalized tissueis present.Postoperative infection rates in this group exceed 40%. The use of antimicrobials in dirty and some contaminated procedures is not classified as prophylaxis but as treatment for a presumed infection.
