Preoperative Skin Preparation: Soap Selection Guidelines

For preoperative skin preparation, antimicrobial soap (such as chlorhexidine gluconate) is recommended over plain soap for surgical hand antisepsis and patient skin preparation. 1, 2

Surgical Hand Antisepsis Options

Antimicrobial Soap Method

  • Remove rings, watches, and bracelets before beginning 1
  • Clean underneath fingernails using a nail cleaner under running water 1
  • Apply antimicrobial soap and scrub hands and forearms for manufacturer-recommended time (usually 2-6 minutes) 1
  • Pay special attention to nails, cuticles, and interdigital spaces 2
  • Rinse thoroughly with water 1, 2
  • Dry completely with sterile towel 2

Alcohol-Based Hand Rub Method

  • First prewash hands and forearms with non-antimicrobial soap 1
  • Dry hands and forearms completely 1
  • Apply alcohol-based surgical hand-scrub product with persistent activity per manufacturer's instructions 1
  • Allow hands and forearms to dry thoroughly before donning sterile gloves 1

Patient Preoperative Skin Preparation

  • Apply chlorhexidine gluconate liberally to surgical site 2
  • Swab for at least 2 minutes 2
  • Dry with a sterile towel 2
  • Repeat procedure for an additional 2 minutes 2
  • Dry with a sterile towel 2

SOAP Documentation Format Example for Preoperative Skin Preparation

Subjective

  • Patient scheduled for [specific surgical procedure]
  • No known allergies to chlorhexidine or other antiseptic agents
  • No previous adverse reactions to skin preparation products

Objective

  • Surgical site identified and marked
  • Skin intact with no visible lesions, rashes, or infections
  • Preoperative vital signs stable

Assessment

  • Patient ready for preoperative skin preparation
  • No contraindications to standard antiseptic protocol

Plan

  • Perform surgical hand antisepsis using chlorhexidine gluconate antimicrobial soap for 2-6 minutes
  • Prepare patient's skin with chlorhexidine gluconate applied for two consecutive 2-minute applications
  • Document completion of skin preparation according to protocol
  • Proceed with sterile draping and surgical procedure

Important Considerations

Product Selection

  • Provide personnel with efficacious hand-hygiene products with low irritancy potential 1
  • Consider product compatibility with gloves and other skin care products 1
  • Do not add soap to partially empty dispensers ("topping off") as this can lead to bacterial contamination 1

Technique Specifics

  • When using soap and water, wet hands first with water 1
  • Apply manufacturer-recommended amount of product 1
  • Rub hands vigorously for at least 15 seconds, covering all surfaces 1
  • Avoid hot water as it increases risk of dermatitis 1
  • Use disposable towels rather than multiple-use cloth towels 1

Skin Care

  • Provide hand lotions or creams to minimize irritant contact dermatitis 1
  • Non-petroleum based lotions are preferred as petroleum can deteriorate latex gloves 1

Common Pitfalls to Avoid

  • Inadequate scrub time (less than manufacturer recommendations)
  • Insufficient attention to nails, cuticles, and interdigital spaces
  • Failure to completely dry hands before donning gloves
  • Using hot water which can increase skin irritation 1
  • Wearing artificial fingernails or extenders, which harbor microorganisms 1

By following these evidence-based guidelines for preoperative skin preparation, healthcare providers can significantly reduce the risk of surgical site infections and improve patient outcomes.
