What Researchers Did
This study looked back at three years of data from 111 patients who received 2,394 hyperbaric oxygen treatments to identify factors that increase the risk of ear and sinus barotrauma.
What They Found
Out of 2,394 treatments, 35 patients experienced barotrauma symptoms, leading to an overall rate of 3.05 cases per 100 treatments. The ears were affected in 95% of cases, and symptoms were most common during a patient's first three treatments. Female patients had a significantly increased risk (RR = 2.14) compared to males, and patients under age 40 were at a higher risk (RR = 3.00) than those 40 and older.
What This Means for Canadian Patients
Canadian patients undergoing hyperbaric oxygen therapy should be aware that ear and sinus barotrauma is a potential side effect, especially during their initial treatments. Healthcare providers may consider closer monitoring or specific preventative strategies for female patients and those under 40, who appear to be at a higher risk. This information can help tailor patient education and treatment approaches to minimize discomfort.
Canadian Relevance
No direct Canadian connection identified. This study focuses on a side effect of hyperbaric oxygen therapy and does not cover a Health Canada-recognized indication for HBOT.
Study Limitations
This study was retrospective, meaning it looked at past data, which may not fully capture all risk factors or precisely define the safest compression rates for hyperbaric oxygen therapy.
