Preoperative Skin Preparation: 9 Goals for Surgical Site Infection Prevention

Preoperative skin antisepsis achieves nine critical objectives:

1. SSI Prevention: Primary goal—reduce microbial load at incision site.
2. Transient Flora Reduction: Remove contaminating microbes acquired from environment.
3. Antiseptic Efficacy: Chlorhexidine gluconate (CHG) 2% or 4% or povidone-iodine (PVI) per guideline.
4. Debris Removal: Cleanse dirt, oils, blood, prep residues.
5. Hair Management: Clip (not shave) if necessary; shaving increases SSI risk.
6. Sterile Field Integrity: Prepped area remains uncontaminated through draping and procedure.
7. Enhanced Healing: Clean wound edges promote primary intention healing.
8. Patient Comfort: Non-irritating agents, proper drying prevents chemical dermatitis.
9. Guideline Compliance: WHO, CDC, AORN, NICE protocols standardize practice.

Application: back-and-forth friction scrub (2 min CHG, 2 min PVI dry time); allow full dry before draping.
