Chronic wounds that fail to progress through normal phases of healing present a significant healthcare burden owing to prolonged treatment and associated costs. Traditional wound care typically involves regular dressing changes, which can be painful. Recent approaches have explored the use of lidocaine to manage pain and red-light irradiation (RLI), known for its anti-inflammatory and cell proliferation effects, to potentially enhance wound healing.
To investigate the therapeutic efficacy of lidocaine wet compression (LWC) combined with RLI for chronic wounds.
We enrolled 150 patients with chronic wounds from the Wound and Ostomy Outpatient Clinic of the Second Hospital of Anhui Medical University from April to September 2022. The wounds were treated with dressing changes. The patients were randomly assigned to the control and experimental groups using a random number table and given the same first dressing change (2% LWC for 5 min and routine dressing change). From the second dressing change, in addition to 2% LWC for 5 min and routine dressing change, the experimental group received RLI, whereas the control group continued to receive the same LWC and dressing change. The first and second dressing changes were performed on days 1 and 2, respectively. The third dressing change was performed 3 d after the second change. The frequency of subsequent dressing changes was determined based on wound exudation and pain. Pain during the first three dressing changes was evaluated in both groups. The average number of dressing changes within 28 d and the degree of wound healing on day 28 were also recorded.
During the initial dressing change, no noticeable differences were observed in the pain levels experienced by the two groups, indicating similar pain tolerance. However, during the second and third dressing changes, the experimental group reported significantly less pain than the control group. Furthermore, over 28 d, the experimental group required fewer dressing changes than the control group.
Notably, the effectiveness of wound healing on the 28th day was significantly higher in the experimental group than that of in the control group. The combination of LWC and RLI was effective in reducing early-stage pain, pro
Core Tip: The combination of lidocaine wet compression (LWC) and red-light irradiation (RLI) has shown promising results for the treatment of chronic wounds. A study involving 150 patients demonstrated that the addition of RLI to LWC resulted in reduced pain during dressing changes, improved wound healing, decreased the frequency of dressing changes, and enhanced overall quality of life. During the second and third dressing changes, the experimental group experienced significantly less pain than the control group. Over 28 d, the experimental group required fewer dressing changes on average and achieved higher effectiveness in wound healing by day 28. This combination therapy has the potential to provide effective relief to patients with chronic wounds and improve their outcomes.
