#1 - Clean- Any incision thru non-infected material NOT in major tracts
#2 - Clean, Contaminated- Baseline in GI, respiratory, reproductive, urinary tracts
#3 - Contaminated- Presence of contained acute inflammation (not chronic)- Dry, but not wet and active gangrene- Example: inflamed, non-perforated appendix

#2 - Clean, Contaminated- Baseline in GI, respiratory, reproductive, urinary tracts
#3 - Contaminated- Presence of contained inflammation- Dry, but not wet and active gangrene- Example: inflamed, non-perforated appendix
#4 – Dirty/Infected- Incision into infected material- Spilled purulence or fecal material, wet gangrene - Example: perforated and inflamed appendix with presence
of purulence outside of appendix

Wound Class Quiz
• 1st Slide – actual KPSF cases– Scenario explained with choices– Circulator recording marked by *asterisk– Think about the baseline of the procedure– Then think about anything that would
change that baseline
• 2nd Slide– Shows the answer in multiple asterisks– Note on key or important criteria

What is the wound class?
A patient under went a Whipple for cancer. Surgery included a cholecystectomy. Gallbladder was documented as having changes consistent with chronic cholecystitis.

What is the wound class?
Patient underwent a breast biopsy. The operative report noted multiple areas of fatty necrosis on the large mass. There was also necrotic tissue around the mass.

What is the wound class?
Patient underwent laparoscopic appendectomy. The pre op CT scan reported the appendix contained a fecalith. There was no mention of infection, rupture or inflammation on the operative report.

What is the wound class?
Patient underwent an exploratory laparoscopic for possible small bowel obstruction. The procedure performed was terminal ileum resection. The operative report states “necrotic cecum and appendix”.

What is the wound class?
With a patient in significant abdominal pain, a preop CT scan indicated patient had SBO (small bowl obstruction). An ex-lap was performed and adhesion lysis freed up a SBO.

Note: Bowel was never incised, therefore surgery is on par with hernia repair

What is the wound class?
Patient had necrotic foot d/t complications from peripheral ischemia r/t 150 pack years of smoking. Surgeon performed below knee amputation where the incision was clean without infection.

What is the wound class?
Long term diabetic patient had infected gangrenous below-the-knee-amputation stump after vascular grafts failed to improve leg perfusion. Surgeon performed above the knee amputation where the initial incision expressed lymphatic pus. AKA surgery successful.

What is the wound class?
Patient underwent a rectopexy procedure (rectal prolapse) where a portion of the rectum was resected. The anastamosis was checked for patency/leaks by rigid sigimoidoscopy.
