The effects on maternal and fetal cardiovascular and acid-base variables after the administration of etomidate in the pregnant ewe.

Etomidate is an intravenous (IV) hypnotic agent characterised by its cardiovascular stability. Although etomidate has been satisfactorily used in veterinary and human obstetrics, little is known about its effects on the fetus. This study determined the cardiovascular and acid-base effects of etomidate administration in the pregnant ewe and her fetus.

Placental transfer of etomidate in pregnant ewes after an intravenous bolus dose and continuous infusion.

Etomidate (ETO) is a short-acting intravenous (IV) anaesthetic characterised by cardiopulmonary stability and favourable pharmacokinetics. Although ETO has been used satisfactorily in obstetrical anaesthesia, little is known about placental transfer and the drug's pharmacokinetics in the fetus. Placental transfer in pregnant ewes has been evaluated following the administration of an IV bolus of 1mg/kg ETO; and after a 1-h infusion of 100 microg/kg min(-1) ETO preceded by an IV bolus of 1mg/kg.

Effects of preoperative administration of meloxicam on whole blood platelet aggregation, buccal mucosal bleeding time, and haematological indices in dogs undergoing elective ovariohysterectomy.

The purpose of the study was to evaluate the effect of preoperative administration of meloxicam, a non-steroidal anti-inflammatory drug used for pain control, on primary haemostasis in dogs. Twenty healthy female dogs undergoing elective ovariohysterectomy were enrolled in the study. Sixty minutes before pre-anaesthesia, a single dose of meloxicam (0.
