Xylazine-ketamine anesthesia in the horse

Yohimbine reduces neuropathology induced by ketamine/xylazine anesthesia.

Ketamine, an NMDA receptor antagonist, is commonly used in combination with xylazine, an alpha 2-adrenergic receptor agonist, to induce surgical anesthesia in birds and other vertebrates. Problems associated with this anesthetic combination include impaired thermoregulation, compounded by the inability to feed while anesthesia lasts (approximately 6 h after a single dose), and the ketamine-indu...

Differential effects of ketamine/xylazine anesthesia on the cerebral and cerebellar cortical activities in the rat.

Cerebellum is a highly organized structure with a crystalline morphology that has always intrigued neuroscientists. Much of the cerebellar research has been conducted in anesthetized animals, particularly using ketamine/xylazine combination in rats. It is not clear how and to what extent the cerebellar cortical circuitry is affected by this anesthesia. In this study, we recorded spontaneous and...

The Effects of Xylazine-Ketamine Anesthesia on Intraocular Pressure in Dogs

Glaucoma is defined as the increase in the intraocular pressure (IOP) causing visual loss due to the circulation deficits of the aqueous humor. The IOP measurement can be obtained without any problem in calm animals. However, some animals do not allow IOP measurement without sedation or anesthesia. The purpose of this study is to determine the effect of xylazine HCl (as a sedative) and ketamine...

Comparison of thiopental and ketamine+xylazine anesthesia in ischemia/reperfusion-induced arrhythmias in rats.

BACKGROUND/AIM To investigate the influence of thiopental (85 mg/kg, intraperitoneally (ip)), and ketamine+xylazine (ketamine 75 mg/kg and xylazine 8 mg/kg, ip) anesthesia on the incidence and duration of ischemia/reperfusion-induced arrhythmias. MATERIALS AND METHODS Myocardial ischemia was induced by a 6-min ligation of the left anterior descending coronary artery, followed by a 6-min reper...
