What Researchers Did
This review examined existing literature concerning venous air embolism, focusing on its causes, how it affects the body, and its management.
What They Found
Venous air embolism is an infrequent complication of invasive medical procedures, affecting the cardiovascular, pulmonary, and central nervous systems with severity ranging from no symptoms to immediate cardiovascular collapse. Therapeutic interventions include mechanical measures like positioning and air withdrawal, and hyperbaric oxygen therapy shows some promise in reducing bubble size.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
The review notes that randomised, controlled trials are still needed to demonstrate the efficacy of hyperbaric oxygen therapy for venous air embolism.
