Case Study: Application of Class 4 Laser Therapy in Post-Operative Healing of Infected Trauma

Introduction

After the occurrence of pet trauma infection, clinical symptoms such as localized redness, elevated skin temperature, exudation, and inflammatory infiltration are common. In severe cases, this can lead to skin ulceration, suppuration, and tissue adhesion. Poor post-operative healing of infected wounds is a frequent challenge in clinical practice. If a pet self-licks or scratches the wound, or if nursing care is inadequate, further skin damage can occur, severely hindering the recovery process.

Class 4 laser therapy is an advanced physical treatment for infected trauma and wound rehabilitation. It is safe, non-invasive, and effectively provides anti-inflammatory and bactericidal effects. By relieving pain and reducing inflammation, it accelerates the growth of granulation tissue and overall wound closure. This report documents the recovery process of post-operative healing for infected trauma using VETMEDIX (FotonMedix) laser equipment, providing a practical reference for clinical rehabilitation.

05 Case Summary

Short-term Recovery: The veterinary team at Hangzhou Songzi Pet Hospital initiated a targeted Class 4 laser therapy protocol immediately following surgical suturing of the infected trauma. During the treatment cycle, the localized redness and swelling gradually subsided, and wound exudation decreased significantly. The patient’s pain response was markedly reduced, leading to a decrease in self-licking and scratching behaviors. The wound site progressively dried and began to scab, while the pet’s appetite and mental state returned to normal levels.

Long-term Follow-up: Long-term follow-up results after discharge showed that the infected wound had completely healed. The scabs shed naturally, and the local skin returned to a smooth, flat state. No common post-operative complications—such as ulceration, tissue adhesion, excessive scar hyperplasia, or chronic infection recurrence—were observed. Currently, the pet has regained full mobility and returned to a healthy lifestyle.

Conclusion: This case proves the significant clinical value of VETMEDIX small animal high-power laser therapy in the post-operative healing of infected trauma. Utilizing Photobiomodulation (PBM) technology, deep tissue laser therapy non-invasively acts on the infected site to improve local blood circulation, dissipate inflammatory edema, and alleviate pain. By inhibiting the reproduction of pathogenic microorganisms and accelerating tissue repair, it offers clear advantages in safety, efficacy, and speed of recovery, serving as a reliable technical reference for similar clinical cases.
