Evaluation of the Therapeutic Efficacy of Moist Wound Healing After Fractional CO2 Laser Surgery

Abstract

Background

With the popularization of laser therapy, an increasing number of patients are undergoing fractional CO₂ laser therapy. It is particularly important to exercise caution and accelerate wound healing after laser surgery.

Aims

This study aimed to examine the clinical efficacy of moist wound healing after fractional CO₂ laser therapy.

Patients/Methods

A total of 15 individuals volunteered to undergo fractional CO₂ laser therapy. The facial skin was irradiated with a fractional CO₂ laser in the deep mode, with an energy of 15 mJ/cm² and a density of 5%. The left and right sides of the faces were considered the observation and control groups, respectively. After laser therapy, medical cold compress patches were applied on the skin in the control group once a day for approximately 10–15 min, whereas erythromycin ophthalmic ointment was applied on the skin in the observation group 6 times daily for wound care. The wound healing time, duration of erythema, and occurrence of adverse reactions were monitored in both groups.

Results

The observation and control groups received different nursing interventions. The time to regression of erythema and swelling was significantly shorter in the observation group than in the control group. In addition, the scab formed at the wound site was thinner, and shedding was faster in the observation group than in the control group. The Clinical Erythema Assessment score of the observation group was significantly lower than that of the control group (p < 0.05). The wound healing time was 5.73 ± 0.70 days in the observation group and 7.73 ± 0.72 days in the control group, with the difference being statistically significant (p < 0.05). After 30 min and 12 h of nursing intervention, the Visual Analog Scale score of the observation group was significantly lower than that of the control group (p < 0.05). However, after 24 h of treatment, neither group showed significant pain. Both groups showed varying degrees of acne, pustules, and exudation, which subsided within 7 days. Furthermore, the control group had 2 cases of mild pigmentation, which resolved within 3 months. Neither group experienced adverse reactions such as skin infection, depigmentation, or scar formation.

Conclusion

Moist healing therapy can accelerate wound healing and reduce the duration of erythema and edema after fractional CO₂ laser therapy, demonstrating potential clinical application value.
