Evidence of renal tubular injury in canine patients after elective desexing.

Objective: To investigate the frequency of perioperative acute kidney injury (AKI) in American Society of Anesthesiologists (SA) Grade I canine patients undergoing elective desexing using urine microscopy techniques and assess if pre- and intraoperative factors affect risk of developing AKI.

Design: Prospective observational clinical study conducted between September 2020 and October 2020.

Setting: University teaching hospital.

Effects of continuous positive airway pressure on respiratory function in sedated foals.

Objective: To characterize the effects of continuous positive airway pressure (CPAP) delivered by a commercial human CPAP device on respiratory function in foals with pharmacologically induced respiratory suppression.

Design: Prospective randomized, cross-over study comparing CPAP with spontaneous respiration and oxygen insufflation.

Setting: University veterinary teaching hospital.

Evaluation of Masimo signal extraction technology pulse oximetry in anaesthetized pregnant sheep.

Objective: Evaluation of the accuracy of Masimo signal extraction technology (SET) pulse oximetry in anaesthetized late gestational pregnant sheep.

Study Design: Prospective experimental study.

Animals: Seventeen pregnant Merino ewes.

Conditioned response to a magnetic anomaly in the Pekin duck (Anas platyrhynchos domestica) involves the trigeminal nerve.

There have been recent calls to develop protocols that collect unambiguous measures of behaviour using automatic techniques in conditioning experiments on magnetic orientation. Here, we describe an automated technique for recording the behaviour of Pekin ducks in a conditioning test that allows them to express unrestricted searching behaviour. Pekin ducks were trained to find hidden food in one corner of a square arena below which was placed a magnetic coil that produced a local magnetic anomaly.
