Maintaining wild animals in captivity often requires chemical immobilisation to achieve various diagnostic, surgical and management interventions. Four dholes, two Indian grey wolves and four Indian jackals were immobilised using ketamine-xylazine combination for either medical or management interventions. Based on the estimated body weight, canids were darted upon with 6-8 mg kg-1 ketamine and...

BACKGROUND Anesthesia sometimes suppresses ventricular tachyarrhythmias (VT) resistant to conventional pharmacological treatment. METHODS AND RESULTS To know (1) whether deep anesthesia inhibits abnormal repolarization-related VT and (2) if α2-adrenoreceptor (AR) agonistic action is associated with the antiarrhythmic effect of anesthetics, the incidence of VT in a rabbit model of acquired lon...

BACKGROUND AND OBJECTIVES The aim of this study was to investigate the relationship between inhalation anesthetics and hearing in mice. MATERIALS AND METHODS As inhalation anesthetics, isoflurane was used. Auditory brainstem response and distortion product otoacoustic emission were used as measurement of hearing. Mice were divided into 2 groups. 'Isoflurane group' consisted of mice that were ...

A combination of 100 mg/ml of ketamine hydrochloride (Ket) and 20 mg/ml of xylazine hydrochloride (Xyl) was used to immobilize coypus (Myocastor coypus). Eight mature coypus (four males and four females) were injected intramuscularly with doses ranging from 2.33 to 6.25 mg/kg of KET and 0.25 to 0.86 mg/kg of Xyl. The mean (+/- SE) time for induction, arousal, and recovery were 7.3 +/- 2 min, 23...

the viewpoint of not only animal welfare but also the reliability of pharmacological studies. The type of anesthetics used may vary depending on the type of experiment required or the study design. Some anesthetics have cardioor renoprotective effects, which may be relevant in designing ischemiareperfusion protocols. Several studies have examined the influence of commonly used anesthetics on th...

OBJECTIVE To determine the sensitivity to an equal dose of ketamine/xylazine injection at anesthetic dose in a chronic model of hypernatremia. METHODS This study was conducted at the Department of Physiology, Zanjan University of Medical Science, Zanjan, Iran in 2004. Sixty male Wistar rats, weighing 250 +/- 20 g were randomly allocated to 3 groups. The control group was provided with tap wat...

The last few years have seen an increase in the variety of in vivo experiments used for studying cerebellar physiological mechanisms. A combination of ketamine and xylazine has become a particularly popular form of anesthesia. However, because nonanesthetized control conditions are lacking in these experiments, so far there has been no evaluation of the effects of these drugs on the physiologic...

The aim of this study was to compare the duration of analgesia produced by epidural injection of ketamine, lidocaine and xylazine in West African dwarf goats. Three healthy West African dwarf goats of varying ages were used for this study. After administration of each drug, the onset of action was recorded and the duration of action of each drug was determine through pin prick method at ten (10...
