Signalment 

Non-human primate (Chimpanzee), 32yrs, Male (vasectomized), “Flyn”

History   

Full thickness wound to lateral right thigh sustained during a fight with another chimpanzee.

Diagnostics and Exam Findings   

Surgery was performed March 26th to suture the large skin flap. Within a few days, all edges of the wound had been re-opened by the chimps and the flap was detached from the thigh along 2 edges. 

Laser Treatment Details  

Laser therapy was initiated on April 18th after surgical site failure, utilizing the preset deep wound protocol, delivering a fluence of 7 J/cm². Treatment was adjusted as the size of the wound decreased with therapy.

Frequency of Treatment   

A total of 34 treatments have been done so far, ranging from daily to every 2 to 3 days.

Other Treatments   

Standard of care was applied including oral antibiotics (amoxicillin/clavulanic acid), probiotic (biokult), paracetamol and meloxicam. Wound management was performed twice daily with wound lavage using sterile saline and topical treatments to keep the wound moist. Mechanical debridement of the wound was performed as and when needed. To date no further anaesthetics have been needed.
