Figure 2 Mean arterial blood pressure (MAP) and systemic vascular resistance (SVR)
of calves undergoing umbilical surgery under inhalation (INH; n=10), injection (INJ;
n=10) and high volume caudal epidural anaesthesia (EPI; n=10). Baseline values (-
60) are determined in the standing calf in the operating theatre. Between -60 and -30
min, calves were anaesthatised and positioned into dorsal recumbency (light grey
underlay). The surgical period is marked by a dark grey underlay. Symbols with a dot
differ significantly from baseline (p < 0.05). For each given point in time, significant
differences between experimental groups are indicated by different letters.
