[Effects of epidural injection of amitraz, xylazine or dimethyl sulfoxide in cows]
نویسندگان
چکیده
The effects of epidurally amitraz (0.4mg/kg), xylazine (0.05mg/kg) or 10% dimethyl sulfoxide (5.0ml) over heart rate (HR), systolic arterial pressure (SAP), respiratory rate (RR), ruminal motility (RM), rectal temperature (RT), head height (HH), and latency to heat-evoked reflexes (LSPR – skin of perineal region; LHWR – hoof withdrawal reflex) were evaluated in cows. HR and RM decreased in amitraz and xylazine groups. Only xylazine group showed statistical difference over RR, SAP and HH. LSPR and LHWR were prolonged in both α-2 agonist groups. Amitraz epidural administration does not induce severe systemic effects, and induces prolongation of the latency to heat-evoked reflexes in a minor degree than xylazine, at the used dosages, in cows.

The aim of the present study was to determine whether the addition of dexamethasone (DEX) or epinephrine to lidocaine (LID) altered the characteristics of anesthesia and cardiorespiratory variables following caudal epidural application in cows. Twenty adult dairy cows were randomly assigned to receive one of the treatments of LID (0.2 mg/kg), DEX (8 mg), lidocaine-dexamethasone (LIDEX; 0.2 mg/k...

The aim of this study was to determine whether anesthesia consisting of sedation induced by intramuscular administration of xylazine-diazepam and lumbosacral analgesia induced by epidural administration of lidocaine and xylazine is satisfactory for castration and ovariohysterectomy in cats. Six adult (3 male and 3 female, 2.5 ± 0.5 years of age) cats (mean body weight ± SD, 2.2 ± 0.44 kg) were ...
