What does the Canada Hyperbarics research database contain?

The Canada Hyperbarics research database contains 14,603 PubMed-indexed HBOT-related records, sourced from PubMed and updated weekly (Thursdays). The database spans human clinical studies, systematic reviews, case reports, and preclinical research; not every record is a clinically actionable human study. Filter by clinical condition, study type (RCT, systematic review, case series), evidence tier, year, or Canadian-authored records (244 total). Each study includes a structured 5-section AI-generated summary covering question, methods, key findings, clinical takeaways, and limitations, with citation and a link to the original publication.

The influence of hypoxia on tissue regeneration in oral and maxillofacial surgery - a systematic review

Gäde A, Schiegnitz E, Eckert A, Sagheb K, Al-Nawas B, Kupka J

Out of 5790 initial studies, nine met the inclusion criteria for this review. These studies examined interventions such as gene therapy targeting HIF-1α, oxygen-releasing biomaterial scaffolds, hyperbaric oxygen treatment, and hypoxia preconditioning of stem cells. While some interventions showed enhanced bone formation and vascularization, hyperbaric oxygen treatment consistently improved bone healing.

The effectiveness of different treatment methods in the treatment and prevention of medication-related osteonecrosis of the jaw: A systematic review and Bayesian network meta-analysis

Zhang N, Jiang M, Zhang C, Pan Y, Xu R

This systematic review and Bayesian network meta-analysis of 1,064 patients with medication-related osteonecrosis of the jaw found that the treatments studied improved healing rates compared to conventional surgery alone (RR 1.44, 95% CI 1.20 to 1.71, p less than 0.001) and reduced new cases in high-risk patients (RR 0.10, 95% CI 0.04 to 0.29, p less than 0.001). When treatments were ranked by a probability-weighted score called SUCRA, BMP-2 combined with L-PRF scored highest for healing (89.3%), hyperbaric oxygen scored second (84.1%), and YAG laser combined with low-level laser therapy scored third (67.8%). These SUCRA scores reflect a statistical ranking across the network of studies, not a measured cure or success rate for any single treatment.

Treatment of Sleep Disorders Following Traumatic Brain Injury: A Systematic Review and Network Meta-Analysis

Wang Y, Yan J, Su L, Wang B

This review of 22 randomised controlled trials with 1299 patients found that nonpharmacological treatments, including hyperbaric oxygen therapy (HBOT), cognitive behavioral therapy (CBT), acupuncture, and transcranial direct current stimulation (tDCS), significantly improved sleep outcomes. Specifically, HBOT from one trial, along with CBT, acupuncture, tDCS, and problem-solving therapy, significantly improved Pittsburgh Sleep Quality Index (PSQI) scores.

Hyperbaric Oxygen Therapy in Managing Chronic Pain Syndromes - A Systematic Review

Leys A, Hans G, Saldien V, Wildemeersch D

The review included eleven randomised controlled trials with a total of 480 participants, primarily focusing on fibromyalgia (8 studies) with sample sizes ranging from 17 to 71 participants. For fibromyalgia patients, HBOT consistently improved pain, daily functioning, and quality of life, with some studies showing better results compared to control groups. There was limited evidence of possible benefit for complex regional pain syndrome and trigeminal neuralgia, but no meaningful improvement was found for radiation-induced brachial plexopathy.

Gas Therapies for Chronic Wounds: Comparative Effectiveness, Safety, and Evidence Certainty-A Systematic Review and Network Meta-Analysis

Zheng X, Li T, Wang J, Gao L

This review included 27 randomised controlled trials with 1673 participants. Overall, gas therapies significantly increased complete wound healing compared to standard care, with a risk ratio of 2.17 (95% CI 1.61-2.94). However, a network analysis ranked standard care highest for effectiveness (93.9%), with ozone therapy and topical oxygen ranking next, and HBOT ranking mid-range.

Hyperbaric Oxygen Therapy for Chronic Venous Leg Ulcers: A Prospective Randomised Controlled Trial

Nikolić D, Pasternak J, Manojlović V, Budinski S, Nikolić M, Batinić N

In this open-label randomised trial of 80 adults with venous leg ulcers that had not responded to standard care, the group receiving hyperbaric oxygen (20 sessions at 2.4 ATA, 90 minutes) plus standard care had a larger reduction in ulcer area at 30 days than the standard-care-only group (62.1% versus 41.7%, p less than 0.001). Complete healing by 90 days occurred in 62.5% of the hyperbaric oxygen group versus 30.0% of the standard-care group. Oxygen levels in the tissue (TcPO2) rose from 26.1 to 150.3 mmHg in the hyperbaric oxygen group, and pain scores dropped more in that group as well. Three patients (7.5%) had mild ear barotrauma that resolved on its own.

Effects of Hyperbaric Oxygen Therapy on Myocardial Injury and Inflammatory Biomarkers: A Systematic Review With Qualitative Synthesis

Almomany M, Rawashdeh Z, Alshyyab M, Alnabulsi A, Alodat L, Alshamaly S, et al.

Five clinical studies involving 431 patients showed that hyperbaric oxygen therapy (HBOT) reduced CPK levels by up to 35% and improved heart function in acute heart attacks. HBOT also lowered inflammation and heart damage markers after cardiac surgery and reduced inflammatory markers in chronic heart disease.

Survival rate and risk factors of implants in patients with head and neck neoplasms: a systematic review and meta-analysis

Liu Y, Yang C, Song Y, Sun Y, Wang H, Zhang Y, et al.

This meta-analysis of 42 studies (2,448 patients, 10,164 implants, follow-up ranging from 1 to 12 years) found an overall pooled implant survival rate of 88 percent (95% CI: 85 to 90 percent). Implant survival was lower in bone that had been irradiated compared to non-irradiated bone (18 studies, RR 0.95, 95% CI: 0.91 to 0.99, p equals 0.03), and lower in grafted bone compared to native bone (15 studies, RR 0.92, 95% CI: 0.88 to 0.97, p less than 0.001). Separately, implant survival rates were higher in patients who had undergone hyperbaric oxygen therapy compared to those who had not (5 studies, RR 1.47); the abstract does not report this HBO comparison broken down by irradiated or grafted bone status. Heterogeneity across the included studies was high (I squared equals 94.9 percent, p less than 0.001).
