An otherwise healthy eight-year-old Irish Sports Horse mare weighing 590 kg underwent general anaesthesia for bilateral tarsal arthroscopy and arthrotomy with subsequent removal of two osseous intra-articular fragments. The horse was positioned in dorsal recumbency, with the pelvic limbs stretched backwards. The anaesthetic was uneventful except for a brief period of hypertension and mild hypoxaemia. However, a bilateral pelvic limb paralysis became evident during recovery, while the thoracic limb function and mental state of the horse remained normal. Postanaesthetic myopathy and fractures were excluded early on in the investigation and repeated neurological examinations revealed initially intact nociception, withdrawal and cutaneous trunci reflexes in both pelvic limbs, as well as normal anal and tail tone. A bilateral femoral neuropathy was suspected at first. However, the horse’s neurological function progressively deteriorated over the following night, leading to a flaccid paralysis of both pelvic limbs and complete loss of withdrawal and cutaneous trunci reflexes, and anal and tail tone, suggesting a central lesion. A histopathological examination was consistent with postanaesthetic myelomalacia.

A nine-year-old female Yorkshire Terrier weighing 5.8 kg required anaesthesia for a bilateral phacoemulsification to treat diabetic cataracts. Perioperatively, rocuronium bromide was administered intravenously to achieve centralisation of the eye. Immediately after injection of the rocuronium, the dog developed tachycardia, hypertension and bronchospasm. At this time, no association between the rocuronium and the adverse reaction was made due to the lack of reports of such an event in dogs. A second dose was therefore administered once the animal's spontaneous efforts to breathe indicated partial loss of neuromuscular blockade, this time without adverse effects. However, a third dose of rocuronium resulted in similar signs as the first injection, suggesting an association between the rocuronium and the observed reaction. The signs resolved spontaneously and the dog recovered uneventfully in the intensive care unit from where it was discharged 48 hours after the surgery.

tracheal tumours in cats are rare, and most primary tumours respond well to complete surgical excision. providing secure airway management during resection of the trachea is particularly challenging and in some cases represents a limitation to surgery. We present the case of a cat with a primary tracheal neoplasm located close to the carina, undergoing complete resection. successful management of the airway was accomplished by intubating the distal tracheal stump with a modified polyvinyl chloride endotracheal tube. effective seal of the airway and adequate ventilation of both lungs were achieved. We describe a reliable, simple, low-cost technique which provides control of the airways even in situations where the distal stump of the trachea is either too short or non-existent.

A 3‐year‐old cat was presented in the clinic following a fall from height. Due to suspected urinary bladder wall rupture, the cat was scheduled for diagnostic imaging. The cat was premedicated with 0.1 mg/kg methadone intravenously. General anaesthesia was induced with a bolus of propofol of 2 mg/kg administered intravenously using a syringe pump. Shortly after, the patient became apnoeic and showed signs of very deep anaesthesia. It was then noticed that almost half of the 20 ml syringe used to administer the bolus was empty, which led to the conclusion that due to a slip‐of‐the‐finger error, a bolus of 8 ml of propofol (20 mg/kg) was accidentally administered. No additional anaesthetics were administered. The cat resumed spontaneous ventilation and was extubated at 70 and 130 minutes after induction, respectively. Full recovery took 23 hours, and the cat showed no permanent damage or side effects in the following 19 days.
