Evaluation of urine specific gravity as a predictor of hypotension during anaesthesia in healthy dogs premedicated with dexmedetomidine.

Objective: To investigate the relationship between urine specific gravity (USG) and the risk of arterial hypotension during general anaesthesia (GA) in healthy dogs premedicated with dexmedetomidine and methadone.

Study Design: Prospective clinical cohort study.

Animals: A total of 75 healthy client-owned dogs undergoing GA for elective tibial plateau levelling osteotomy.

The effect of neuraxial morphine on postoperative pain in dogs after extrahepatic portosystemic shunt attenuation.

Objective: To investigate the analgesic effect of epidural morphine after surgical extrahepatic portosystemic shunt (EHPSS) attenuation.

Study Design: Randomized clinical trial.

Animals: A total of 20 dogs with a congenital EHPSS.

Preliminary investigation comparing a detomidine continuous rate infusion combined with either morphine or buprenorphine for standing sedation in horses.

Objective: To compare sedative and analgesic properties of buprenorphine or morphine for standing procedures combined with a detomidine continuous rate infusion (CRI).

Study Design: Blinded, prospective, randomized clinical pilot study.

Animals: Ten horses presented for dental or sinus procedures.

Perioperative trends in plasma colloid osmotic pressure in horses undergoing surgery.

Objective: To compare perioperative trends in plasma colloid osmotic pressure (COP) between horses undergoing orthopedic and colic surgery.

Design: Prospective clinical study September 2009-January 2011.

Setting: Veterinary university teaching hospital.

Early experience with continuous positive airway pressure (CPAP) in 5 horses -- a case series.

This case series is the first report of the use of CPAP (continuous positive airway pressure) ventilation in adult horses. Two horses and 3 ponies anesthetized for orthopedic procedures in lateral recumbency received 10 cm H(2)O CPAP. During anesthesia, arterial oxygen partial pressure tended to increase and arterial carbon dioxide pressure tended to increase despite increased minute ventilation index.

Comparison of invasive and non-invasive blood pressure monitoring during clinical anaesthesia in dogs.

Monitoring blood pressure during anaesthesia is widely recommended in man and animals. The accuracy of any device used to measure blood pressure is an important consideration when selecting monitoring equipment, the ANSI/AAMI SP10 standard is widely cited in this respect in recent veterinary publications. Blood pressure was monitored using invasive and non-invasive techniques during clinical anaesthesia in 19 dogs.
