rSO ₂ in the anterior tibial muscle during sevoflurane preconditioning and in a time-matched interval. rSO₂ in the anterior tibial muscle of patients during sevoflurane preconditioning (IPC + Sevoflurane, n = 20) and rSO₂ of patients without sevoflurane preconditioning (IPC, n = 20) during a corresponding time-matched interval between induction of anesthesia and ischemic preconditioning. There was no significant difference between the groups. rSO₂ has been normalized to baseline prior to induction of anesthesia to facilitate group comparison.
