What Researchers Did
Researchers assessed the effects of short- and long-term hyperbaric oxygen therapy (HBOT) on nasal mucociliary clearance (MCC) in 47 nondiabetic patients.
What They Found
Both short-term (average 8 sessions) and long-term (average 20 sessions) HBOT significantly affected nasal mucociliary clearance (P < 0.001) immediately after treatment. However, only long-term exposure caused significant and potentially irreversible elongation of MCC at a 6-month follow-up, suggesting a dose-dependent effect.
What This Means for Canadian Patients
Canadian patients undergoing long-term hyperbaric oxygen therapy, especially for conditions like middle ear or sinonasal infections, should be aware of potential irreversible negative effects on nasal mucociliary clearance. Close monitoring and patient education about these risks are important for those receiving chronic HBOT.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or with Canadian participants.
Study Limitations
A limitation of this study is its relatively small sample size of 47 nondiabetic patients, which may limit the generalizability of the findings.
