The efficacy of hyperbaric oxygen in the treatment of acute acoustic trauma is unclear.
Clinical Bottom Line:
- Poorly reported trial cannot be evaluated
Citation: 1.Pilgramm M. Clinical and animal experiment studies to optimise the therapy for acute acoustic trauma. Scandinavian Audiology (Suppl) 1991; 34:103-122.
Clinical Scenario:A patient with acute hearing loss following acoustic trauma.
Three-part Question:For patients with acute acoustic trauma, does the addition of hyperbaric oxygen to the standard treatment regimen result in any improvement in final hearing or reduction in tinnitus?
Search Terms:Hyperbaric oxygenation, trauma/acoustic.
The Study:Double-blinded randomised controlled trial. Patients with hearing loss 40dB following acoustic trauma within 48 hours and without improvement greater than 20dB after 24 hours in the absence of therapy.
Control group (N = ?):Unknown.
Experimental group (N =?):Unknown
The Evidence:
None given!
Comments:
1. Results and methodology not clearly reported.
2. Text suggests that hyperbaric oxygen may be of some additional benefit, but supporting results not given.
