Wenhui LI, Changgeng FU, Lei XV, et al. - Researchers assessed clinical evidence of hyperbaric oxygen therapy in the management of diabetic foot ulcers, via this overview of systematic reviews. They analyzed systematic reviews (SRs) assessing the impacts of hyperbaric oxygen therapy in individuals with diabetic foot ulcer. Inclusion criteria were fulfilled by 11 SRs/MAs. They found limited clinical evidence in favor of hyperbaric oxygen therapy in the management of diabetic foot ulcers, routine application of hyperbaric oxygen therapy to all patients with diabetic foot ulcers, particularly those with non-ischemic diabetic foot ulcers, is not advised. Certain potential of hyperbaric oxygen therapy to promote ulcer healing as well as decrease amputation rate in patients with ischemic diabetic foot ulcers has been observed, but because these results are supported by low quality and small quantity of the SRs/MAs, widespread recommendations require high-quality studies with rigorous study designs and larger samples.
