What Researchers Did
Researchers looked back at treatment records for patients with thromboangiitis obliterans (Buerger's disease) who had wounds from poor circulation, comparing those who got hyperbaric oxygen treatment (HBOT) alongside standard care to those who got standard care alone.
What They Found
This was a non-randomised, retrospective study of 97 patients with ischaemic wounds from thromboangiitis obliterans treated across two centres between 2007 and 2016. Ten months after starting treatment, major amputation was significantly less common in the HBOT group than in the group that did not get HBOT (2 out of 47 patients versus 13 out of 50 patients). The study also reports that adding HBOT to conventional treatment brought significant benefits for wound healing and for controlling rest pain, though it does not give the specific figures for those two outcomes.
What This Means for Canadian Patients
For patients with Buerger's disease and non-healing ischaemic wounds with severe pain, this study suggests HBOT added to standard treatment may lower the chance of losing a limb to major amputation and may help wounds heal and pain improve. It does not say HBOT works for other conditions, and it does not describe risks or side effects of treatment.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The study was retrospective and non-randomised rather than a randomized controlled trial, so the two treatment groups may have differed in ways that affected outcomes, and the authors themselves call for multi-centre, prospective, randomized studies with blinded outcome analysis to confirm these results.
