Xander 14yo MF- Pressure sore post bladder surgery 14/01/25
Photobiomodulation played a pivotal role in Xander’s recovery by supporting the wound through each phase of healing while preventing further tissue compromise. In the early stages, PBM likely improved local circulation and oxygenation in already ischemic tissue, helping to limit the progression of necrosis. As the wound opened, it provided effective analgesia and reduced inflammation, creating a more stable environment for repair. During the proliferative phase, PBM stimulated fibroblast activity, collagen synthesis, and angiogenesis, which is reflected in the development of strong, healthy granulation tissue. Importantly, treatment of the surrounding at-risk tissue helped protect against further breakdown. Overall, consistent PBM accelerated healing, improved tissue quality, and contributed to the transition from a severe, full-thickness pressure injury to a controlled and progressing wound
Management Approach
Medical
Systemic antibiotics to manage infection risk
Mechanical
Offloading and repositioning to prevent further pressure damage
