What Researchers Did
Researchers reported a case of a postpartum patient with prolonged epidural blockade and tomographic evidence of epidural air who underwent hyperbaric therapy.
What They Found
Computed tomography and magnetic resonance imaging revealed 4-6 mL of air in the epidural space, leading to hyperbaric therapy 14 hours after the epidural infusion was discontinued. The patient made a complete recovery and was discharged without any neurologic sequelae.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada or by Canadian researchers.
Study Limitations
As a single case report, this study cannot establish a definitive cause-and-effect relationship between epidural air and prolonged neurological block or generalize findings to a broader population.
