Efficacy of the Er:YAG Laser Debridement on Patient-Reported Pain and Bacterial Load in Chronic Wounds
In Brief
A clinical study evaluating Erbium:Yttrium-Aluminum-Garnet (Er:YAG) Laser Debridement and Scalpel/Curette Debridement for Wound Open and 2 related conditions. Completed, enrolled 22 participants.
Detailed Summary
Bacterial load is frequently associated with impaired healing of chronic wounds. As well, sharp debridement is often associated with pain, causing patient distress, and thereby occasionally contributing to inadequacy of debridement, leading to a delay in wound healing. The purpose of this study is to assess the efficacy of the Sciton Laser in reducing bacterial load and patient distress in patients with chronic wounds, in efforts to expedite the wound healing process.

Timeline
Interventions
Laser debridement entailed usage of an Er:YAG laser, employing the JOULE® machine (Sciton, Inc., Palo Alto, California). Full-field ablation was performed using the 2940 nm Er:YAG Contour TRL Resurfacing® application with the following settings: fluence - 50 J/cm2, spot overlap - 50%, pattern repeat - 0.5 seconds, spot size - 3-mm (Figure 1). Debridement was carried out until all fibrinous and/or necrotic tissues were removed, and healthy, bleeding tissue was visualized.
Using a scalpel/curette, each patient's chronic wound is debrided until healthy, viable tissue is noted.
