Menegaz, Rubia G., Daniel R. Kapusta, Antonio M. Cabral. Role of intrarenal a2-adrenoceptors in the renal responses to xylazine in rats. Am J Physiol Regulatory Integrative Comp Physiol 278: R1074–R1081, 2000.—This study examined the contribution of intrarenal a2-adrenoceptor mechanisms to the enhanced urine flow rate (V) and urinary sodium excretion (UNaV) responses in ketaminexylazine-anesthe...

OBJECTIVE To evaluate the influence of premedication with tramadol on xylazine-ketamine anaesthesia in young pigs. STUDY DESIGN Prospective, randomized, blinded cross-over study. ANIMALS Ten young Niger hybrid pigs: mean weight 6.1 +/- 0.6 kg. METHODS Pigs were anaesthetized twice. Xylazine (2.5 mg kg(-1)), ketamine (25 mg kg(-1)) and atropine (0.04 mg kg(-1)) were administered by intramu...

Nine aardvarks (Orycteropus afer) were captured in the southern Free State, South Africa, for the placement of abdominal radio transmitters. Five combinations of ketamine hydrochloride with xylazine hydrochloride, midazolam or medetomidine hydrochloride were used to induce anaesthesia. In some cases the level of anaesthesia was maintained with 1.5% halothane. A mixture of ketamine hydrochloride...

The objective of this study was to compare 3 total intravenous anesthetic infusion combinations in adult horses for cardiopulmonary changes, muscle relaxation, duration of recumbency, and quality of recovery. This was a prospective, randomized, crossover, experimental study. Six healthy, adult, mixed-breed horses weighing 460 ± 30 kg were used. The 3 total intravenous anesthetic combinations us...

The influence of increasing the dosage of ketamine on anaesthesia induced by a combination of ketamine, xylazine and midazolam in pigs was determined by assessing the onset of action (OAN), duration of analgesia (DAN), anaesthesia time (ANT), and recovery time (RCT) in 10 growing pigs (Mean weight: 18.2 +/- 1.65 kg) receiving either 10 mg/kg intramuscular (i.m.) injection of 10% ketamine, 2 mg/...

This study evaluated the use of the injectable anesthetic, alphaxalone, as a single agent and in combination with ketamine, xylazine, and morphine in the Chilean rose tarantula, Grammostola rosea. Between two and four animals were evaluated for each anesthetic protocol, and two unanesthetized animals were evaluated for comparative purposes. Anesthetic duration, depth, and quality were assessed ...

OBJECTIVE To compare three anaesthetic protocols for umbilical surgery in calves regarding adequacy of analgesia, and cardiopulmonary and hormonal responses. STUDY DESIGN Prospective, randomised experimental study. ANIMALS Thirty healthy German Holstein calves (7 female, 23 male) aged 45.9 ± 6.4 days. METHODS All calves underwent umbilical surgery in dorsal recumbency. The anaesthetic pro...
