Does 50% nitrous oxide in oxygen alter haemodynamic responses in patients undergoing coronary artery surgery?
Does 50% nitrous oxide in oxygen alter haemodynamic responses in patients undergoing coronary artery surgery?
Administration of 50% nitrous oxide during coronary artery surgery does not appear to decrease left ventricular performance or deteriorate myocardial oxygenation.
No takes yet. Share an insight, caveat, or question.
Nitrous oxide may preserve LV performance in coronary surgery; case report leaves open need for controlled confirmation.
Lilleaasen et al. (1981) studied this question.
