What Researchers Did
Researchers conducted a double-blinded, randomized controlled trial comparing staged versus linear chamber compression protocols to assess the incidence and severity of middle ear barotrauma during hyperbaric oxygen therapy.
What They Found
The staged compression protocol did not significantly reduce the overall incidence of middle ear barotrauma (48%) compared to the linear protocol (62%, P=0.12). However, the staged protocol led to significantly less severe deteriorations in middle ear barotrauma grades (P=0.028).
What This Means for Canadian Patients
For Canadian patients undergoing hyperbaric oxygen therapy, a staged compression protocol may not prevent middle ear barotrauma but could reduce its severity. This could lead to a more comfortable treatment experience, minimizing the impact of barotrauma.
Canadian Relevance
This study was conducted in Australia and has no direct Canadian connection.
Study Limitations
The study's primary outcome, a significant reduction in the overall incidence of middle ear barotrauma, was not achieved with the staged protocol.
