Veterinary anaesthesia and analgesia
-
To compare the distribution of flow from two commercial and one handmade multihole wound infusion catheters. ⋯ Uneven distribution of flow at low infusion speeds may contribute to inconsistent or unsatisfactory pain relief in patients treated with continuous wound infusions of local anesthetics.

Randomized Controlled Trial
Association of partial pressure of carbon dioxide in expired gas and arterial blood at three different ventilation states in apneic chickens (Gallus domesticus) during air sac insufflation anesthesia.
To test whether partial pressure of CO2 in expired gas (PĒCO2) predicts the partial pressure of CO2 in arterial blood (PaCO2) in apneic chickens during air sac insufflation anesthesia at three different ventilation states. ⋯ Arterial blood gases should be used to monitor CO2 during air sac insufflation anesthesia to verify appropriate patient ventilation.

Randomized Controlled Trial
Caudal epidural anti-nociception using lidocaine, bupivacaine or their combination in cows undergoing reproductive procedures.
To evaluate the anti-nociceptive effects of lidocaine, lidocaine-bupivacaine combination or bupivacaine following caudal epidural administration in cows undergoing reproductive procedures. ⋯ Epidurally administered bupivacaine, at a dose of 0.06 mg kg(-1), may provide satisfactory caudal epidural anti-nociception for longer-duration obstetric and surgical procedures.

Randomized Controlled Trial
The effect of fentanyl on the end-tidal sevoflurane concentration needed to prevent motor movement in dogs.
The objectives of this study were to determine the effects of fentanyl on the end-tidal concentration of sevoflurane needed to prevent motor movement (MACNM ) in response to noxious stimulation, and to evaluate if acute tolerance develops. ⋯ Fentanyl doses in the range of 3-12 μg kg(-1) hour(-1) significantly decreased the sevoflurane MACNM. Clinically significant tolerance to fentanyl did not occur under the study conditions.

Randomized Controlled Trial
A comparison between the v-gel supraglottic airway device and the cuffed endotracheal tube for airway management in spontaneously breathing cats during isoflurane anaesthesia.
To compare airway management using the v-gel supraglottic airway device (v-gel SGAD) to that using an endotracheal tube (ETT), with respect to practicability, leakage of volatile anaesthetics and upper airway discomfort in cats. ⋯ Airway management with the v-gel SGAD is a sound and practicable alternative to endotracheal intubation with an ETT. However, larger prospective trials will be needed to draw firm conclusions on the benefits and/or drawbacks of the use of v-gel SGAD for airway management in cats.
