Spinal anaesthesia does not reduce myocardial ischaemia versus general anaesthesia in elderly non-cardiac surgery; extends evidence linking hypothermia and norepinephrine surges to ischaemic risk.
Does spinal anaesthesia compared to general anaesthesia reduce post-operative myocardial ischaemia in elderly patients undergoing major non-cardiac surgery?
In elderly patients undergoing major non-cardiac surgery, the type of anaesthesia does not affect post-operative myocardial ischaemia, but intra-operative hypothermia and sympathetic activation are associated with its development.
