What Researchers Did
Researchers conducted a five-year retrospective study on 2,610 patients in France to describe middle-ear barotrauma after hyperbaric oxygen therapy and identify contributing clinical elements for its prevention and management.
What They Found
Among 2,610 patients receiving hyperbaric oxygen therapy, 262 (10.04%) experienced middle-ear barotrauma, with an incidence of 0.587%. Risk factors included age over 55 years, female gender, a history of ear, nose, and throat conditions, and certain general health issues like smoking or obesity.
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric oxygen therapy should be informed about the potential for middle-ear barotrauma, a common side effect. Identifying risk factors like age over 55, female gender, or a history of ENT issues could help clinicians prevent this complication and ensure successful treatment completion.
Canadian Relevance
This study was conducted in France and does not have a direct Canadian connection.
Study Limitations
As a retrospective study, it relies on existing medical records, which may have limitations regarding data completeness and the ability to establish causality.
