What is the proper procedure for repacking iodoform gauze using aseptic technique and appropriate personal protective equipment?

Procedure for Repacking Iodoform Gauze

Repacking iodoform gauze requires strict aseptic technique with proper hand hygiene, sterile gloves, and avoidance of touching the wound or gauze after antiseptic application, following the same infection control principles used for wound dressing changes.

Pre-Procedure Preparation

Hand Hygiene and Personal Protective Equipment

• Perform hand hygiene before and after the procedure using either conventional antiseptic-containing soap and water or waterless alcohol-based gels or foams 1
• Wear appropriate PPE including mask, protective eyewear, and gown if spattering of blood or body fluids is anticipated 1
• Use sterile gloves for the repacking procedure to maintain aseptic technique throughout 1, 2
• Glove use does not eliminate the need for proper hand hygiene 1

Equipment and Workspace Setup

• Prepare a clean, dry workspace with all necessary sterile supplies opened but not removed from packaging until point of use 1
• Ensure iodoform gauze packaging integrity is intact before opening 1
• Have sterile instruments available if needed to manipulate gauze without direct hand contact 1

Wound Preparation

Antiseptic Application

• Cleanse the wound and surrounding skin with an appropriate antiseptic - 2% chlorhexidine-based preparation is preferred, though tincture of iodine, iodophor, or 70% alcohol are acceptable alternatives 1
• Allow the antiseptic to remain on the site and air dry completely before proceeding 1
• If using povidone iodine, allow at least 2 minutes of contact time or longer until completely dry 1
• Do not palpate or touch the wound after antiseptic application unless maintaining strict aseptic technique 1

Gauze Repacking Technique

Aseptic Handling

• Maintain aseptic technique throughout the entire procedure - this is the cornerstone of preventing wound contamination 1, 2
• Remove old iodoform gauze carefully and discard appropriately
• Handle new sterile iodoform gauze only with sterile gloved hands or sterile instruments 1, 2
• Avoid touching any non-sterile surfaces once sterile field is established 2

Packing Method

• Pack the wound cavity loosely with iodoform gauze to allow for drainage and prevent tissue compression 3
• Ensure gauze contacts all wound surfaces without excessive pressure
• Leave a small tail of gauze visible outside the wound for ease of removal at next dressing change 3

Post-Procedure Care

Dressing Application

• Cover the packed wound with sterile gauze dressing 1
• If the wound is bleeding, oozing, or the patient is diaphoretic, use a gauze dressing rather than transparent semi-permeable dressing 1
• Secure the dressing appropriately to maintain sterility

Documentation and Follow-up

• Document the procedure including date, time, and any observations about wound condition 1
• Change iodoform gauze packing typically once weekly until complete healing, though frequency may vary based on wound condition 3

Critical Safety Considerations

Toxicity Monitoring

• Be vigilant for signs of iodoform toxicity, particularly in patients with extensive wounds, diabetes, or prolonged treatment duration 4, 5, 6
• Warning signs include confusion, hallucinations, altered consciousness, tachycardia, vomiting, and fever 4, 5, 6
• Plasma iodine levels can become dangerously elevated (>150 μg/dL) with daily dressing changes on large wounds 4, 6
• Discontinue iodoform immediately if toxicity is suspected - symptoms typically resolve within 3-8 days after removal 5, 6

Common Pitfalls to Avoid

• Never reuse gauze or instruments between patients 1
• Do not apply organic solvents like acetone or ether to the wound 1
• Avoid overpacking the wound, which can impede drainage and healing 3
• Do not submerge the dressed wound in water 1
