To determine and compare cardiorespiratory and recovery effects of sevoflurane, isoflurane, and halothane in horses. ⋯ Sevoflurane induced cardiorespiratory effects that were comparable to those of isoflurane and halothane. Cardiac output was greater and respiratory rate was less than that for halothane at 1.5 MAC. Sevoflurane anesthesia was characterized by good control of anesthesia depth during induction, maintenance, and recovery. Recovery time after sevoflurane anesthesia was comparable to that for isoflurane, and recovery was smooth and controlled in a manner consistent with recovery from halothane.

To determine whether plasma von Willebrand factor (vWf) concentration changes during the estrous cycle and pregnancy in Doberman Pinschers with type-I von Willebrand's disease (vWd) and in mixed-breed dogs with normal vWf, and if so, whether alterations in vWf concentration are associated with changes in serum concentrations of reproductive hormones. ⋯ The increase in vWf concentration in pregnant bitches may be associated with changes in concentrations of reproductive hormones. However, the increase in vWf concentration during pregnancy may involve other factors because vWf concentration did not change during the estrous cycle of nonpregnant dogs despite increases in concentrations of estradiol-17 beta and progesterone.
