What Researchers Did
Researchers documented the recovery of a 2-year-old girl who received normobaric and hyperbaric oxygen therapy after suffering severe brain injury from cold water drowning.
What They Found
Initially, MRI showed cerebral atrophy and significant brain matter loss, and the patient had no speech, gait, or responsiveness 48 days post-injury. After starting normobaric oxygen on day 56 and then hyperbaric oxygen therapy (HBOT) at 1.3 ATA air for 40 sessions on day 79, she achieved normal speech and cognition with assisted gait. An MRI 27 days after HBOT showed near-normalization of brain ventricles and reversal of atrophy.
What This Means for Canadian Patients
This case report suggests that hyperbaric oxygen therapy might offer a potential treatment option for severe brain injury following drowning, even when initiated weeks after the initial incident. While not a standard treatment, it highlights the possibility of neurological and brain volume recovery in complex cases that may otherwise have limited options.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
As a single case report, this study's findings cannot be generalized to a larger population and require further investigation through controlled clinical trials.
