1. Indications

The application of skin cell suspension autograft (SCSA) is indicated for the treatment of various types of wounds, particularly in the following scenarios:

• Full-thickness wounds that require advanced healing techniques to promote tissue regeneration and repair.
• Partial-thickness wounds where SCSA can be layered over a split-thickness skin graft to enhance healing outcomes.
• Mixed-depth wounds that necessitate a combination of treatment approaches to address different tissue depths effectively.

2. Procedure

The procedure for applying skin cell suspension autograft (SCSA) involves several critical steps to ensure effective treatment of the wound and donor sites:

• Preparation of the wound bed is the first step, where the area is cleaned and assessed to ensure it is suitable for grafting. This may involve debridement of necrotic tissue to create a healthy base for the application of the SCSA.
• Application of the primary dressing follows, which is a non-adherent, small pore dressing that is contoured to fit the wound bed. This dressing is cut to shape and secured only at the lower border of the wound using glue, sutures, or staples to allow for proper application of the SCSA.
• Spraying of the SCSA is then performed, where the prepared skin cell suspension is evenly sprayed over the wound bed and donor sites. This can be done either alone over a partial-thickness wound or in a layered fashion over a previously applied split-thickness skin graft.
• Securing the primary dressing is the next step, where the dressing is completely affixed over the entire wound bed, extending to the edges, and secured with staples, glue, or sutures to ensure it remains in place during the healing process.
• Application of secondary and tertiary dressings is the final step, where an absorbent dressing is placed over the primary dressing, followed by a third layer of absorbent gauze and bandaging to provide additional protection and support to the wound.

3. Post-Procedure

After the application of the skin cell suspension autograft, careful monitoring of the wound is essential to assess healing and detect any signs of infection. Patients may be advised on how to care for the dressing and when to return for follow-up evaluations. The expected recovery period will vary depending on the size and depth of the wound, as well as the patient's overall health. It is important to ensure that the dressings remain intact and that the wound is kept clean and dry to promote optimal healing.
