What Researchers Did
Researchers conducted a systematic review to evaluate the effectiveness of hyperbaric oxygen therapy (HBOT) for inner ear decompression sickness (IEDCS) by synthesizing data from 24 studies representing 539 cases.
What They Found
Out of 3,683 records, 24 studies involving 539 cases of inner ear decompression sickness (IEDCS) were included, revealing a mean diver age of 44 and an average dive depth of 29 metres. Despite 68% showing dysfunction on laboratory testing, only 37% had residual symptoms on discharge, though vestibular rehabilitation was underutilized and only 46% underwent patent foramen ovale screening.
What This Means for Canadian Patients
Canadian divers experiencing inner ear decompression sickness (IEDCS) may benefit from hyperbaric oxygen therapy (HBOT), with many showing symptom resolution upon discharge. However, it is crucial for patients to receive comprehensive follow-up, including vestibular rehabilitation and screening for patent foramen ovale, to ensure optimal long-term recovery.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The review was limited by variable follow-up durations and assessment methods across the included descriptive observational studies.
