Core Temperatures and Calculated Vasoconstriction Thresholds (at a Mean Skin Temperature of 34°C).

	Core Temperature (°C)	Vasoconstriction Threshold (°C)
Control (no anesthesia, Studies 2 & 3)	36.9 (0.4)	37.0 (0.3)
Study 1 (Desflurane – Lateral Position)
2.6 Vol %	36.3 (0.3)	35.6 (0.3)
Study 2 (Desflurane)
3.5 Vol %	35.8 (0.4)	35.3 (0.5)
5.6 Vol %	34.6 (1.2)	33.5 (1.7)
Study 3 (Isoflurane)
0.55 Vol %	36.4 (0.2)	36.3 (0.3)
0.70 Vol %	35.9 (0.5)	35.7 (0.7)
0.85 Vol %	35.1 (0.7)	34.5 (0.9)
1.0 Vol %	33.6 (0.8)	32.5 (1.2)

Within each study, all thresholds differ significantly. Results are presented as means (SDs).
