Perrins 1967 RCT + subsequent case series support HBOT for compromised grafts.
Overview
HBOT is UHMS-approved for compromised skin grafts and flaps — specifically those failing due to ischaemia, infection, or inadequate blood supply. Routine use for uncomplicated grafts is not indicated; HBOT is reserved for salvage of threatened tissue.
How HBOT Works
HBOT delivers dissolved oxygen directly to graft or flap tissue with marginal vascular supply, maintaining cellular viability during the critical window. HIF-1α-driven angiogenesis accelerates neovascularisation. Enhanced antimicrobial activity reduces infection-mediated graft failure.
Clinical Protocol
Typical protocol
20–30 sessions at 2.0–2.4 ATA
Evidence level
Moderate — UHMS approved
FDA / regulatory status
FDA-approved indication
Early intensive course: 2–3 sessions per day for the first 48 hours of recognised compromise. Then daily sessions until clinical resolution — typically 10–30 total sessions.
Cautions & Considerations
Reserved for compromised (threatened) grafts/flaps — not routine use.
