Does a longer duration of anaesthesia increase the incidence of non-urological perioperative complications and mortality in surgical patients?
Anaesthesia duration exceeding 6 hours is independently associated with an increased risk of perioperative complications and mortality.
Longer anaesthesia is associated with an increase in the incidence of perioperative complications and mortality, especially when the duration of anaesthesia is >6 h. This increase appears to be independent of patient's preoperative health status, tumour extent and blood loss.
