Name of the Procedure:

Contact Layer, Sterile Dressing Application

Common Names:
  • Contact Layer Dressing
  • Sterile Dressing Application
Technical/Medical Terms:
  • A6207 Contact layer, sterile, more than 16 sq. in. but less than or equal to 48 sq. in., each dressing


In this procedure, a sterile contact layer dressing, sized between 16 and 48 square inches, is applied to a wound. This type of dressing helps protect the wound, encourages healing, and minimizes discomfort.


The primary purpose of a contact layer dressing is to treat various types of wounds, such as:

  • Surgical incisions
  • Ulcers (e.g., pressure, diabetic)
  • Minor burns
  • Trauma wounds

By providing a protective barrier, the dressing aims to:

  • Prevent infection
  • Absorb wound exudate
  • Promote optimal healing conditions


This procedure is indicated for:

  • Patients with wounds that require a sterile environment for healing
  • Cases where a non-adherent dressing is necessary to minimize pain and trauma during dressing changes
  • Wounds with moderate to heavy exudate that need an absorbent dressing


Patient Instructions:
  • Clean the wound as directed by a healthcare provider.
  • Avoid applying any ointments or medications unless specified.
  • Follow any fasting or medication adjustment guidelines given by the healthcare provider.
Pre-Procedure Assessments:
  • Wound assessment to determine the size and type of dressing required.
  • Evaluation for any allergies to dressing materials or adhesives.

Procedure Description

  1. Preparation of Materials: Gather sterile dressing, gloves, and any other necessary medical supplies.
  2. Hand Hygiene: Perform hand hygiene and don sterile gloves.
  3. Wound Cleaning: Clean the wound using an appropriate solution to remove any debris or bacteria.
  4. Dressing Selection: Choose a sterile contact layer dressing sized between 16 and 48 square inches.
  5. Application: Carefully place the contact layer dressing over the wound, ensuring it covers all areas without overlapping onto healthy skin.
  6. Securing the Dressing: Use secondary dressings or adhesive tape to secure the contact layer in place if required.
Tools, Equipment, or Technology:
  • Sterile contact layer dressing (A6207)
  • Sterile gloves
  • Wound cleaning solution
  • Secondary dressings or adhesive tapes


The dressing application typically takes about 10-15 minutes, depending on the wound's complexity and size.


This procedure can be carried out in various settings, including:

  • Hospitals
  • Outpatient clinics
  • Home care settings


The procedure is generally performed by:

  • Nurses
  • Wound care specialists
  • Physicians (if part of a larger treatment plan)

Risks and Complications

Common Risks:
  • Minor discomfort
  • Allergic reaction to dressing material or adhesive
Rare Risks:
  • Wound infection
  • Delayed wound healing
Management of Complications:

Healthcare providers will monitor the wound and change dressings regularly to manage any complications.


Expected Benefits:
  • Reduced risk of infection
  • Enhanced wound healing
