The study's purpose was to evaluate the effect of post-surgical photobiomodulation therapy (PBMT) in dogs.
  • 20 large-breed dogs were selected for elective gastropexy and randomly divided into a control (CG, n = 10) and a PBMT group (PBMTG, n = 10)
  • All dogs received appropriate systemic & post-op medications for analgesia as well as local blocks with lidocaine
  • Incisional gastropexy was performed in all animals, and the researcher performing scoring for outcome measures was blinded.
  • PBMTG received PBMT immediately after surgery using an Abdominal Disorders protocol on the CTS-DUO (9J/cm2 at 12W power administered ON contact over the entire abdomen, except for directly over the skin incision [off-contact]).
  • Outcome measures included pain scoring using the Glasgow Composite Measure Pain Scale – Short Form (CMPS‑SF) at several time points from 1-24 h post‑endotracheal extubation & the percentage of dogs in each group that had eaten at the same time points.
  • No rescue analgesia was needed for any animal

Results 
Significant differences were observed in the pain scores between CG and PBMTG between 1- 4 hrs post-extubation AND PBMTG had a significantly higher proportion of animals eating up to the 8 hr evaluation.


Conclusion 
Adding post-surgical photobiomodulation to a standard anesthesia and analgesia protocol reduced pain scores and increased the proportion of animals that resumed eating compared to the standard protocol alone.
