Table 2.

End‐tidal isoflurane (ETISO) and hemodynamic parameters of six anesthetized dogs (mean ± SD) that did not undergo intervention (Control treatment) or that underwent hemorrhage and randomly received volume replacement with lactated Ringer's solution (LRS treatment) or with 6% tetrastarch (TS treatment) at a ratio of 3 : 1 or 1 : 1 the volume of shed blood, respectively. Variables recorded before hemorrhage (BL), immediately after blood withdrawal over 30 minutes (BW), immediately after volume replacement over 30 minutes (VR), and during 4 hour after VR
