What Researchers Did
This case report describes a 67-year-old man who experienced an air embolism, a rare but serious complication, during an upper endoscopy procedure.
What They Found
During the endoscopy, the patient developed an air embolism, which led to a decrease in his pulse oxygen saturation and a delayed recovery from sedation. He eventually recovered in the intensive care unit with some weakness in his left upper limb, despite not receiving hyperbaric oxygen therapy.
What This Means for Canadian Patients
Air embolism is a serious but rare complication of medical procedures like endoscopy, which can lead to life-threatening events. While this patient recovered without HBOT, hyperbaric oxygen therapy is a recognized treatment for arterial gas embolism, which includes air embolism, and can improve patient outcomes by reducing bubble size and improving oxygen delivery to damaged tissues.
Canadian Relevance
No direct Canadian authors or study site were identified. However, air embolism falls under the Health Canada-recognized indication of arterial gas embolism, for which hyperbaric oxygen therapy is an approved treatment.
Study Limitations
As a single case report, the findings of this study cannot be broadly applied to all patients undergoing endoscopy.
