Table 3. Anesthesia Data and Vasoconstriction Threshold

Values are mean ± SD. The anesthesia data did not differ significantly among the groups. Vasoconstriction threshold is the compensated core temperature triggering a skin-temperature gradient = 0°C. Patients who vasoconstricted and those remaining vasodilated are both included. Vasoconstriction threshold (and other parameters) were determined only in patients who had vasoconstriction.

DAN = diabetic autonomic neuropathy.

*P < 0.05, all controls versus  DAN-positive group.

†P < 0.05, young group versus  DAN-positive group.

‡P < 0.05, older group versus  DAN-positive group.

§P < 0.05, before versus  after vasoconstriction in each group.

∥P < 0.05, DAN-negative group versus  DAN-positive group.
