What Researchers Did
Researchers measured saliva urea levels in 30 patients with acute and chronic maxillofacial inflammation before, during, and after hyperbaric oxygenation (HBO) treatment.
What They Found
They found elevated urea concentrations in the saliva of 30 patients after four 40-minute hyperbaric oxygenation sessions, administered at 1.5 atm once daily. These elevated levels are thought to be an adaptive response to eliminate ammonia overproduction and could potentially predict oxygen intoxication in HBO-exposed patients.
Canadian Relevance
This study has no direct Canadian connection or specific relevance to the Canadian healthcare system.
Study Limitations
A limitation of this study is its small sample size of 30 patients and the lack of detailed information on other treatment modalities used.
