What Researchers Did
Researchers described their method of mechanically ventilating and monitoring critically ill children receiving hyperbaric oxygen therapy (HBO2) in a multiplace chamber and reviewed associated complications.
What They Found
Among 32 critically ill, mechanically ventilated children (mean age 4.8 years) treated with HBO2, 21 had necrotizing infections, 9 had carbon monoxide poisoning, and 2 had arterial air embolism. Complications during HBO2 therapy included hypotension (63%), bronchospasm (34%), hemotympanum (13%), and progressive hypoxemia (6%), with only one accidental extubation (3%) occurring during transport.
What This Means for Canadian Patients
This study suggests that critically ill Canadian children requiring mechanical ventilation can safely receive hyperbaric oxygen therapy in a multiplace chamber with close monitoring. While complications may occur, a skilled team can manage them effectively, potentially improving outcomes for conditions like severe infections or carbon monoxide poisoning.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in a university-affiliated children's hospital and regional hyperbaric medicine treatment facility in the United States.
Study Limitations
As a case series, this study's findings are limited by its observational nature and lack of a control group, which restricts generalizability.
