The aim of this study was to compare the cardiovascular and respiratory effects and the bispectral scale index (BIS) as well as the recovery period characteristics in response to treatment with a propofol/alfentanil admixture of different concentrations in dogs undergoing splenectomy. We conducted a prospective, randomised, blinded experimental trial. Anaesthesia was induced and maintained by c...

PURPOSE To compare the cardiopulmonary effects and the quality of anesthesia of the extradural lidocaine in combination with fentanyl or morphine in bitches undergoing ovariohysterectomy. METHODS Sixteen female dogs, were sedated with intramuscular acepromazine (0.05 mg kg-1), followed by anesthetic induction with intravenous propofol (4 mg kg-1), to perform the lumbosacral puncture. The anim...

OBJECTIVE To compare cardiovascular and systemic effects and analgesia during the postoperative period of epidural anesthesia performed with bupivacaine alone or with fentanyl or sufentanil in bitches maintained at a light plane of anesthesia with continuous infusion of propofol. STUDY DESIGN Prospective randomized masked clinical trial. ANIMALS 30 female dogs of various breeds. PROCEDURE...

PURPOSE To investigate cardiorespiratory effects and serum concentration of ropivacaine combined with morphine at different doses. METHODS Sixteen healthy adult female dogs weighting 9.8 ± 4.1 kg were included in the study. Twenty minutes after being premedicated with acepromazine and midazolam, the animals were randomly assigned to receive an epidural injection according to each group: RM0.1...

This study was designed to evaluate effects of xylazine-ketamine anesthesia on plasma levels of cortisol and vital signs during and after laparotomy in dogs. Eight clinically healthy, adult male dogs, weighing 20 kg were used. All dogs were initially sedated by acepromazine. Thirty minutes later, ketamine plus xylazine was used to induce anesthesia. Surgical incision of laparotomy was done. Aft...

The "push-pull" effect denotes the reduced tolerance to +G(z) (hypergravity) when +G(z) stress is preceded by exposure to hypogravity, i.e., fractional, zero, or negative G(z). The purpose of this study was to test the hypothesis that an exaggerated, myogenically mediated rise in leg vascular conductance contributes to the push-pull effect, using heart level arterial blood pressure as a measure...

In the present case report, the comprehensive management of a bilateral mandibular fracture in a single-humped camel including pre-, peri- and post-operative cares is described. A one-year-old camel with the overhanging of the rostral part of the lower jaw which occurred seven days ago was presented. After clinical and radiographic examinations, a bilateral mandibular fracture at the caudal par...

BACKGROUND Hypoxia is a critical secondary injury mechanism in traumatic brain injury (TBI), and early intervention to alleviate post-TBI hypoxia may be beneficial. NVX-108, a dodecafluoropentane perfluorocarbon, was screened for its ability to increase brain tissue oxygen tension (PbtO2) when administered soon after TBI. METHODS Ketamine-acepromazine anesthetized rats ventilated with 40% oxy...
