Haemodynamics in cattle under halothane, isoflurane maintenance anaesthesia in dorsal and lateral recumbency*

An experiment rms conducted to evaluate hoemodynamics in 36 non-descript cattle induced with xylazine-ketamine-glyceyl guaiacolafe anaesthesia in 5% dexfrose administered intravenously and maintainzd under halothane (group I) or isoflurane (group 11) in left lateral (subgroup A), right lateral (subgroup B) anddorsal recumbency (subgroup C) for 30 min. After induction, there was asignificant (P<0.01) fall in mean arterial pressure (MAP) and a significant (P<0.01) elevation in central venous pressure (CVP). The MAP increased significantly (P<0.0l) and the CVP decreased significantly (P<0.01) after intubation. There was a non-significant fall in MAP in group I animals as compared to that in group II animals, whereas the CVP values in both groups were almost similar. Irrespective of the group, both MAP and CVP decreased significantly (P<0.01) under dorsal recumbency as compared to that under lateral rrcurubency. However, the MAP in right lateral recumbency under isoflurane maintenance and recovery was significantly (P<0.01) higher as compared to other body positions and comparable to the preinduction values.
