Veterinary anaesthesia and analgesia
-
To determine the usefulness of an acoustic device to confirm correct placement of extradural needles in horses. ⋯ The acoustic device is useful to assist in the identification of successful or unsuccessful extradural needle placement in the horse.

Randomized Controlled Trial
Clinical pharmacology of methadone in dogs.
To investigate the pharmacokinetics and effects of methadone on behaviour and plasma concentrations of cortisol and vasopressin in healthy dogs. ⋯ When methadone was administered by the SC route, the half-life was longer, but the individual variation in plasma concentrations was greater compared with IV administration. Increased frequency of whining occurred after administration of methadone and may be a drug effect and not a sign of pain. Cortisol and vasopressin concentrations in plasma may not be suitable for evaluating analgesia after methadone treatment.

Randomized Controlled Trial
The bispectral index during recovery from halothane and sevoflurane anaesthesia in horses.
To record the bispectral index (BIS) when horses moved during either halothane or sevoflurane anaesthesia and when they made volitional movements during recovery from these anaesthetics. ⋯ Bispectral indices appear to approximate levels of unconsciousness, suggesting that monitoring the BIS may assist equine anaesthesia. However, it does not predict intra-operative movement.

Comparative Study
Comparison of a method using the HemoCue near patient testing device with a standard method of haemorrhage estimation in dogs undergoing spinal surgery.
To compare an estimate of blood loss obtained using measurements from the Hemocue photometer with a standard estimate in dogs undergoing spinal surgery. ⋯ The HemoCue may be used to help estimate blood loss in dogs undergoing spinal surgery.
-
To evaluate the extent sensory and motor blocks produced by the epidural injection of different volumes of 0.25% bupivacaine (Bu) with methylene blue (MB), in dogs. ⋯ Relatively high volumes (0.6 mL kg(-1)) of 0.25%, BU and MB were needed to produce an effective sensory and motor block caudal to the umbilicus, but all spinal cord segments were reached by MB at this dose.
