What Researchers Did
Researchers conducted a literature search to identify cases of cerebral air embolism (CAE) following esophagogastroduodenoscopy (EGD) and included their experience with one patient.
What They Found
The study identified 31 cases of post-EGD cerebral air embolism, with a mean patient age of 63.7 years, and 38.7% (n=12) of patients being women. Esophageal dilatation was performed in 38.7% (n=12) of cases, and 20% (n=4) of patients with documented echocardiography had a patent foramen ovale. Hyperbaric oxygen therapy was used in 48% of cases.
What This Means for Canadian Patients
This review highlights the rare but serious risk of cerebral air embolism following EGD, emphasizing the importance of prompt recognition and treatment. Canadian patients undergoing EGD should be aware of this potential complication, and healthcare providers should consider hyperbaric oxygen and lidocaine as treatment options.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
The study's limitations include its retrospective nature, reliance on published case reports, and potential for publication bias.
