Table 2. Base Deficit is unchanged in both T/HS groups.

Protective changes in VNS were not a result of different degrees of shock as represented by the base deficit obtained from the animals during shock. There were no statistical differences between the T/HS and the T/HS+VNS groups.

	Pre-shock	After shock	Post 3 hours
T/HS	5.0±4.1	−10.5±4.4*	2.0±0.8
T/HS + VNS	1.25±0.1	−9.25±2.6*	3.0±1.6
