CO Stunning in Pigs: Physiological Deviations at Onset of Excitatory Behaviour.

Stunning by carbon dioxide (CO) inhalation is controversial because it is associated with vigorous movements and behaviours which may or may not be conscious reactions. Furthermore, it is unknown whether some behaviours might indicate the transition into unconsciousness. Our study objective was to investigate the loss of consciousness during CO stunning by linking physiological variables (in particular pH, PaO and PaCO) to the onset of observed behaviours.

High and Hyper: Fentanyl Induces Psychomotor Side-Effects in Healthy Pigs.

Analgesic effects of fentanyl have been investigated using behavior. The behavioral effects of fentanyl and possible serotonergic influence are largely unknown. We therefore investigated behavioral effects of fentanyl, with or without the serotonin antagonist ketanserin, in pigs.

Cardiovascular effects of intravenous morphine in anesthetized horse.

Objectives: To investigate whether morphine causes a change in mean arterial blood pressure (MAP) heart rate (HR) and oxygen extraction (OE) rate in healthy horses anesthetized with isoflurane and a dexmedetomidine infusion.

Material And Methods: The study design was prospective clinical, randomized, blinded two groups including 33 horses. All horses were sedated with romifidine IV, and anesthesia was induced with midazolam IV and ketamine IV and maintained with isoflurane in oxygen and medical air and a dexmedetomidine infusion.

Lidocaine spray 10% prior to intravenous catheterisation in dogs.

A common and to some degree painful procedure in veterinary practice is to insert an intra-venous catheter. In both human and veterinary medicine, a topical mixture of lidocaine and prilocaine (EMLA cream) has shown to reduce the pain, however a period of 60 min between application and initiation of the procedure is recommended. This time lapse is not always suitable for clinical practise and a shorter time before anaesthetic effect is therefore desirable.

Macrocirculatory Parameters and Oxygen Debt Indices in Pigs During Propofol Or Alfaxalone Anesthesia When Subjected to Experimental Stepwise Hemorrhage.

Pigs are anesthetized when used for emergency procedures live tissue training (LTT) of civilian and military medical personnel or for experimental purposes, but there is a paucity in the literature regarding anesthesia of pigs for this purpose. The main goals of the study were to compare oxygen debt, macrocirculatory parameters, and time to cardiac arrest between pigs in hemorrhagic shock and anesthetized with propofol-ketamine-dexmedetomidine or alfaxalone-ketamine-dexmedetomidine. A prospective, non-blinded randomized study design was used.

Inhibition and facilitation of nociceptively evoked muscular activity by fentanyl or dexmedetomidine in isoflurane-anaesthetized pigs.

Objective: To investigate motor and cardiovascular responses to dexmedetomidine or fentanyl in isoflurane-anaesthetized pigs.

Study Design: Experimental, balanced, block randomized, two-group design.

Animals: A group of 16 crossbred pigs, 55 ± 8 days (mean ± standard deviation) old.

A comparison of respiratory function in pigs anaesthetised by propofol or alfaxalone in combination with dexmedetomidine and ketamine.

Background: General anaesthesia in pigs maintained with intravenous drugs such as propofol may cause respiratory depression. Alfaxalone gives less respiratory depression than propofol in some species. The aim of the investigation was to compare respiratory effects of propofol-ketamine-dexmedetomidine and alfaxalone-ketamine-dexmedetomidine in pigs.

Plasma concentrations at two dexmedetomidine constant rate infusions in isoflurane anaesthetized horses: a clinical study.

Objective: To determine dexmedetomidine plasma concentrations at two infusion rates in isoflurane anaesthetized horses and compare cardiovascular effects and anaesthetic recovery between treatments.

Study Design: Prospective, randomized, masked clinical study.

Animals: Healthy, adult, client-owned, non-food producing horses presented for castration.

Androstenone and testosterone levels and testicular morphology of Duroc boars related to estimated breeding value for androstenone.

Androstenone and testosterone levels in Duroc boars with an estimated breeding value for androstenone (EBV(androstenone)) were followed in the period from birth to sexual maturity. The breeding value for androstenone had been estimated based on androstenone levels in 1202 Duroc boars at an age of 24 weeks. Testosterone and androstenone levels in plasma were recorded in 19 boars at 1 week of age and in their 15 respective litter-siblings at 3 weeks of age.

Physiological evaluation of free-ranging moose (Alces alces) immobilized with etorphine-xylazine-acepromazine in Northern Sweden.

Background: Evaluation of physiology during capture and anesthesia of free-ranging wildlife is useful for determining the effect that capture methods have on both ecological research results and animal welfare. This study evaluates capture and anesthesia of moose (Alces alces) with etorphine-xylazine-acepromazine in Northern Sweden.

Methods: Fifteen adult moose aged 3-15 years were darted from a helicopter with a combination of 3.

Radical surgical resection of locally invasive oro-cutaneous tumors in the buccal region of 2 horses.

Objective: To report treatment and wound healing after radical surgical mass excision in the equine buccal region.

Study Design: Clinical case reports.

Animals: An 11-year-old Warmblood gelding and a 9-year-old Norwegian Trotter gelding.

Evaluation of the bispectral index as an indicator of degree of central nervous system depression in isoflurane-anesthetized horses.

Objective: To determine whether the bispectral index (BIS) can be used as an indicator of degree of CNS depression in isoflurane-anesthetized horses.

Animals: 10 Standardbred and 6 Norwegian cold-blooded trotter stallions admitted for routine castration.

Procedure: A 2-channel referential electrode configuration was used to record EEG for calculation of BIS by the EEG monitor.
