Veterinary anaesthesia and analgesia

Randomized Controlled Trial
The effect of volatile anaesthetics on the relative sensitivity of facial and distal thoracic limb muscles to vecuronium in dogs.
To compare n. facialis-m. nasolabialis (nF-mNL) and n. ulnar-mm. carpi flexorii (nU-mCF) sensitivity to vecuronium during halothane or isoflurane anaesthesia. ⋯ The nF-mNL was more sensitive than nU-mCF to vecuronium, particularly in halothane-anaesthetized dogs.

Randomized Controlled Trial
Assessment of brachial plexus blockade in chickens by an axillary approach.
To assess the brachial plexus block in chickens by an axillary approach and using a peripheral nerve stimulator. ⋯ The brachial plexus block was an easy technique to perform but had a high failure rate. It might be useful for providing anesthesia or postoperative analgesia of the wing in chickens and exotic avian species that have similar wing anatomy.

Randomized Controlled Trial
Fentanyl or midazolam for co-induction of anaesthesia with propofol in dogs.
Propofol may cause adverse effects (e.g. apnoea, hypotension) at induction of anaesthesia. Co-induction of anaesthesia may reduce propofol requirements. The effect of fentanyl or midazolam on propofol dose requirements and cardiorespiratory parameters was studied. ⋯ Fentanyl decreased propofol requirement but did not significantly alter cardiovascular parameters. Midazolam did not reduce propofol requirements and caused excitement in some animals.

Randomized Controlled Trial
A comparison of the effects of propofol and etomidate on the induction of anesthesia and on cardiopulmonary parameters in dogs.
To determine the effects of propofol or etomidate on induction quality, arterial blood pressure, blood gases, and recovery quality in normal dogs. ⋯ Propofol caused a decrease in SAP and MAP which was not observed with etomidate. Etomidate caused longer and poorer recoveries than propofol.

To determine the safety and efficacy of intramuscularly (IM) injected 100% propofol and propofol-dimethyl sulfoxide (DMSO) mixtures. ⋯ One hundred percent propofol is neither safe nor effective when administered via the IM route; presumably as a result of poor systemic uptake of the hydrophobic drug. Newer, water-soluble propofol formulations may circumvent these pharmacokinetic problems, yet local tissue injury might still be possible if high concentrations of free propofol drug are liberated.
