What Researchers Did
Researchers conducted a systematic review and meta-analysis of 15 animal studies to evaluate the efficacy of hyperbaric oxygen (HBO) for treating intracerebral haemorrhage (ICH).
What They Found
They found that hyperbaric oxygen significantly reduced brain water content (-0.982, 95% CI, -1.148 to -0.817; P < 0.01; 57 comparisons) and improved neurobehavioural outcome (-0.767, 95% CI, -1.376 to -0.159; P < 0.01; eight comparisons) in animal models of ICH. HBO was most effective in reducing brain water content when administered 72 hours post-ICH for 4-5 days at 3.0 atmosphere absolute.
What This Means for Canadian Patients
While promising in animal models, these findings do not yet translate directly to human patients. Further research, including clinical trials, is needed before hyperbaric oxygen can be considered for Canadian patients with intracerebral haemorrhage.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The study acknowledged limitations including possible publication bias, poor study quality, and the limited number of studies conducting clinical trials.
