Summary
This study looked at whether using nitrous oxide (laughing gas) during major surgery is safe for people at risk of heart problems. Over 7,000 adults aged 45 and older were randomly assigned to receive either nitrous oxide or a similar gas without nitrous oxide. The researchers tracked deaths and serious heart events like heart attack, stroke, and cardiac arrest for 30 days after surgery to compare the two groups.
