What Researchers Did
Researchers investigated the effects of hyperbaric oxygen therapy on the human coagulation system in 20 patients using point-of-care analyzers and standard laboratory assays.
What They Found
The study found that hyperbaric oxygen therapy significantly increased maximum clot firmness (p < 0.05) and platelet-mediated clot firmness (p < 0.01) as measured by ROTEM. Multiplate analysis also showed platelet activation via thrombin (p < 0.05) and arachidonic acid (p < 0.01) pathways, while standard assays revealed a lower activated partial thromboplastin time (p < 0.05) and higher leukocyte count (p < 0.05).
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric oxygen therapy may experience changes in their blood coagulation system, specifically increased platelet activation and clot firmness. This suggests that healthcare providers should be aware of potential hemostaseologic alterations when treating patients with hyperbaric oxygen, especially those with pre-existing clotting risks.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian participants or institutions.
Study Limitations
A limitation of this study is its relatively small sample size of 20 patients, which may limit the generalizability of the findings.
