BACKGROUND Hyperosmolar solutions have been used in neurosurgery to modify brain bulk and prevent neurological deterioration. The aim of this animal study was to compare the short-term effects of equivolemic, equiosmolar solutions of mannitol and hypertonic saline (HTS) on cerebral cortical microcirculation in a rabbit craniotomy model. METHODS Rabbits(More)
BACKGROUND Hyperosmolar solutions have been used in neurosurgery to modify brain bulk and prevent neurological deterioration. The purpose of the study was to compare the effects of equivolume, equiosmolar solutions of mannitol and hypertonic saline (HTS) on brain relaxation and postoperative complications in patients undergoing elective intracranial tumor(More)
Hemorrhagic shock (HS) represents an acute event with high mortality. The optimal combination of anesthetics that would prevent hemodynamic collapse and allow damage control surgery has not yet been determined. We tested the hypothesis that a combination of dissociative anesthetic ketamine with alpha2-agonist medetomidine (MK group, n=10) would provide(More)
OBJECTIVE To develop a safe and effective immobilization protocol in rhesus monkeys, which is not based on dissociative anaesthetic agent. STUDY DESIGN Prospective, randomised, experimental trial. ANIMALS Twenty rhesus monkeys, weighing 2.6-8.0 kg, 1-3 years of age, of both sexes. METHODS The monkeys received 50 μg kg(-1) medetomidine, 0.25 mg kg(-1)(More)
BACKGROUND The aim of this study was to compare cardiorespiratory and behavioral profile of a new alpha 2-adrenoceptor ligand naphthylmedetomidine with medetomidine in rhesus monkeys. METHODS Naphthylmedetomidine or medetomidine (50 microg/kg) together with ketamine (3 mg/kg) and hyaluronidase (150 IU/kg) i.m was administered to 35 rhesus monkeys.(More)
BACKGROUND Percutaneous transluminal angioplasty and stenting with cerebral protection is a minimally invasive method for carotid artery stenosis treatment, which may be an alternative to surgical endarterectomy. The aim of our study is to evaluate results of endovascular treatment in patients at high risk of endarterectomy. PATIENTS AND METHODS Between(More)
OBJECTIVE The aim of this study was to investigate the effect of a novel alpha-2-adrenoceptor (alpha(2)-AR) agonist, naphthylmedetomidine, on cardiorespiratory function and sedation in rabbits in comparison with medetomidine. STUDY DESIGN Prospective, randomized, experimental trial. ANIMALS Forty-two chinchilla rabbits of both sexes, weighing 2.5-4.5(More)
BACKGROUND Hyperosmolar solutions have been used in neurosurgery to modify brain bulk. The aim of this animal study was to compare the short-term effects of equivolemic, equiosmolar solutions of hypertonic saline (HTS) and sodium lactate (HTL) on cerebral cortical microcirculation and brain tissue oxygenation in a rabbit craniotomy model. METHODS Rabbits(More)
BACKGROUND The aim of the study was to compare the effect of naphthylmedetomidine to medetomidine on the behavior of orangutans and chimpanzees. METHODS The immobilization was performed as part of a medical examination in five chimpanzees and three orangutans. Following pre-medication with midazolam (0.70-1.20 mg/kg p.o.), naphthylmedetomidine (50-70(More)
