What Researchers Did
Researchers analyzed 98 patients with necrotizing soft-tissue infections (flesh-eating disease) treated with surgery, antibiotics, and HBOT to see whether starting HBOT sooner led to better outcomes.
What They Found
Patients who died had significantly longer delays between diagnosis and first HBOT session compared to survivors (p=0.031). Patients who lost limbs also had longer waits before starting HBOT than those who kept their limbs (p=0.031). Earlier HBOT was linked to fewer surgical debridements, shorter hospital and ICU stays, and higher complete wound healing rates.
What This Means for Canadian Patients
For Canadians diagnosed with flesh-eating disease, timing matters: this study suggests that adding HBOT as quickly as possible after diagnosis, not waiting until standard treatments have been attempted, may reduce the chances of death or amputation. Canadians in regions without a nearby hyperbaric chamber face a real disadvantage in accessing time-sensitive treatment.
Canadian Relevance
No direct Canadian connection identified. Necrotizing soft-tissue infection is not a listed OHIP-covered HBOT indication, though it is recognized by Undersea and Hyperbaric Medical Society guidelines.
Study Limitations
This was a retrospective study at a single institution without randomization, so sicker patients may have been delayed for reasons unrelated to HBOT itself.
