Motor responses to stimulation during isoflurane anaesthesia in pigs.

Objective: To investigate motor responses to stimulation during the transition from 'deep' (burst suppression) to 'light' isoflurane anaesthesia in pigs.

Study Design: Prospective, randomized observational study.

Animals: Five castrated male and five female Norwegian landrace pigs, weighing 19-29 kg.

Electroencephalographic and cardiovascular indicators of nociception during isoflurane anaesthesia in pigs.

Objective To evaluate electroencephalographic indices, invasive arterial blood pressure and pulse rate as indicators of nociception during isoflurane anaesthesia in pigs. Animals Ten Norwegian Landrace pigs, five castrated males and five females, weighing between 19 and 29 kg. Materials and methods The pigs were anaesthetized with isoflurane and prepared for the measurement of heart rate (HR), mean arterial pressure (MAP) and the electroencephalogram (EEG).
