L'anesthésie trop profonde majore la mortalité postopératoire (podcast)

A relationship between excessive depth of anesthesia and increase in immediate and late postoperative mortality has been demonstrated in several studies. Low BIS values are associated with mortality in excess independently of hypotension or augmented sensitivity to the effect of halogenates. Burst suppression ratio is also a risk factor of postanaesthesia mortality and of neurological disability in intensive care unit patients. Whether these parameters are causative factors or marker of mortality is not determined.
