Simple technique for aiding thoracic CT scanning of cats without general anaesthesia

Thoracic CT can provide additional diagnostic information in comparison to thoracic radiography for animals with respiratory diseases; however, the requirement of general anaesthesia can be of risk and may not be possible in cats with respiratory distress. The concept of...

Evaluation of three intravenous injectable anaesthesia protocols in healthy adult male alpacas

Few studies have investigated the effects of intravenous injectable anaesthesia in alpacas. The objective of this study was to evaluate three intravenous injectable anaesthesia protocols in healthy adult alpacas exposed to noxious stimulation. A prospective randomised crossover study was done...

Repeated anaesthesia with isoflurane and medetomidine-midazolam-fentanyl in guinea pigs and its influence on physiological parameters

Repeated anaesthesia may be required in experimental protocols and in daily veterinary practice, but anaesthesia is known to alter physiological parameters in GPs (Cavia porcellus, GPs). This study investigated the effects of repeated anaesthesia with either medetomidine-midazolam-fentanyl (MMF) or isoflurane...

Severity classification of repeated isoflurane anesthesia in C57BL/6JRj mice—Assessing the degree of distress

According to the EU Directive 2010/63, the severity of a procedure has to be classified as mild, moderate or severe. General anesthesia is thought to be mild, but the Directive does not differentiate between single and repeated anesthesia. Therefore, we...

The influence of isoflurane anaesthesia on the rat grimace scale

Over 234,000 rats were used in regulated procedures in the UK in 2014, many of which may have resulted in some degree of pain. When using animals in research, there is an ethical and legal responsibility to alleviate or at...

Effect of topically applied anaesthetic formulation on the sensitivity of scoop dehorning wounds in calves

The post-operative effects of three formulations of topical anaesthetic and a cornual nerve block on the sensitivity of scoop dehorning wounds in calves were compared in two trials. In Trial 1, 21 female Holstein dairy calves aged 8 to 24...

Electrophysiological investigation of different methods of anesthesia in lobster and crayfish

Objectives: In search for methods of anesthesia of crustaceans, an implanted electrode into lobster and crayfish CNS enabled us to monitor signal propagation in the nerve system of animals undergoing different protocols. Results: Cooling (tap water 0°C, sea water -1,8°C)...

Comparison of physiological parameters and anaesthesia specific observations during isoflurane, ketamine-xylazine or medetomidine-midazolam-fentanyl anaesthesia in male guinea pigs

Guinea pigs (GPs) are difficult to anaesthetize successfully, the choices for anaesthesia are limited and physiological parameters are likely to be influenced substantially under anaesthesia. We implanted blood pressure radio-telemetry devices into 16 male GPs and subjected them to anaesthesia...

Effect of strain and group size on the response of mice to sconal anaesthesia

The variance of the response to a barbiturate anaesthetic was greater if male mice were caged either singly or in groups of eight than if they were caged in pairs.

Influence of restraint and ketamine anesthesia on adrenal steroids, progesterone, and gonadotropins in rhesus monkeys

Determination of basal circulating hormone levels in nonhuman primates presents a problem since handling or restraint of the animal for venipuncture may introduce sufficient stress to change hormonal secretion. ...Each bleeding was made in conscious [female] monkeys after restraining the...
