What Researchers Did
Researchers investigated the characteristics and risk factors of otological complications in 1115 patients undergoing hyperbaric oxygen therapy (HBOT).
What They Found
Otological symptoms were reported by 165 (14.8%) of 1115 patients, with otalgia being the most common (157/165), followed by ear fullness (13/165) and hearing loss (12/165). Age over 60 years and female sex were identified as independent risk factors, and 50.0% of symptomatic ears showed abnormal otoscopic findings, with 27 requiring myringotomy or tube insertion.
What This Means for Canadian Patients
Canadian patients receiving hyperbaric oxygen therapy should be aware of potential ear complications such as pain or fullness, especially if they are older than 60 or female. Promptly reporting symptoms can lead to timely assessment and interventions, potentially preventing the need to discontinue therapy.
Canadian Relevance
This study was not conducted in Canada and therefore has no direct Canadian connection.
Study Limitations
The study's observational design and specific patient cohort may limit the generalizability of its findings to broader populations.
