Occlusive drainage system for split-thickness skin graft: A prospective randomized controlled trial

Area of Science:

• Dermatology
• Plastic Surgery
• Regenerative Medicine

Background:

• Split-thickness skin grafts (SSTS) are crucial for reconstructing large defects.
• Conventional postoperative care involves moist gauze, petroleum gauze, and splints, often causing pain during dressing changes.
• A novel occlusive drainage system was developed to improve SSTS recipient site management.

Purpose of the Study:

• To compare the efficacy and patient experience of a new occlusive drainage system against conventional methods for SSTS.
• To evaluate graft take, pain levels, and subjective patient satisfaction.

Main Methods:

• A randomized controlled trial involving 28 patients undergoing SSTS.
• Patients were assigned to either the occlusive drainage system or the conventional indirect wet dressing method.
• Outcomes assessed included graft take percentage, pain scores, and patient-reported satisfaction.

Main Results:

• No significant difference in graft take percentage between the two groups.
• The occlusive drainage system group reported significantly less pain and higher satisfaction.
• No wound infections or hypertrophic scar formation were observed in either group during 3-month follow-up.

Conclusions:

• The novel occlusive drainage system is a practical and patient-centered advancement for SSTS recipient site care.
• This method effectively manages SSTS with reduced patient discomfort and improved overall experience.
• The findings support the adoption of this system for better postoperative management of skin grafts.
