Official title

Pharmacogenetics of Adverse Outcomes After Nitrous Oxide Anesthesia

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In this study, we want to find out if laughing gas (nitrous oxide) leads to a higher rate of cardiac complications after surgery in patients with a specific genetic profile (mutations in the MTHFR gene) and if this risk can be prevented by giving patients vitamin B12 and folate during surgery.
