Application of cold atmospheric microwave plasma as an adjunct therapy for wound healing in dogs and cats

[Mechanism of cold atmospheric plasma in treatment of chronic skin ulcer]

Objective

To review the mechanism of cold atmospheric plasma (CAP) in the treatment of chronic skin ulcer, providing a new idea for ulcer therapy.

Methods

The literature about CAP in the treatment of chronic skin ulcers in recent years was extensively screened and reviewed. The treatment principle, active ingredients, and mechanism were summarized.

Results

CAP is partial ionized gas discharged by plasma generator in high frequency under high voltage. It contains electrons, positive and negative ions, reactive oxygen species, reactive nitrogen species, and ultraviolet rays. In vitro and animal experiments show that the active ingredients contained in CAP can inactive microorganisms, against biofilm, regulate immune-mediated inflammatory, promoting blood flow, stimulate tissue regeneration and epithelial formation in the course of wounds healing.

Conclusion

CAP play a role in different stages of chronic skin ulcer healing, with good effectiveness and safety, and broad clinical application prospects. But more studies are needed to explore the indications and dosages of CAP therapy.

Harnessing Non-Thermal Plasma to Supercharge Recovery in Abdominal Surgeries: A Pilot Study

(1) Background: This study aims to evaluate the efficacy and safety of non-thermal plasma (NTP) therapy in accelerating wound healing in patients who have undergone laparoscopic and open surgeries. (2) Methods: NTP was applied using a needle-type reactor with an irradiance of 0.5 W/cm2 on the surgical wounds of fifty patients after obtaining informed consent. Three NTP treatments, each lasting three minutes, were administered hourly. (3) Results: The pilot study showed that NTP-treated surgical wounds healed completely without any signs of infection, dehiscence, pain, or itching. Notably, patients reported minimal pain after the NTP treatment. Visual assessments conducted twenty-four hours after surgery revealed no redness or fluid discharge. Comparisons with traditionally sutured wounds indicated that NTP-treated wounds healed at a rate equivalent to seven days. (4) Conclusions: The application of NTP in laparoscopic and open wounds proved safe and effective, expediting the wound healing process and eliminating clinical risks post-surgery. Significantly, NTP facilitated a healing rate within twenty-four hours, equivalent to seven days for suture-treated wounds, significantly reducing the hospitalization time to a single day. These findings highlight the potential of NTP to be a transformative approach for promoting postoperative recovery.
