Cats were premedicated with dexmedetomidine 3\u2009\u00b5g\/kg and meloxicam 0.1\u2009mg\/kg. Anesthesia was performed using propofol variable rate infusion (adjusted to clinical depth). Heart rate, respiratory rate, hemoglobin oxygen saturation, end-tidal carbon dioxide and systolic, mean and diastolic arterial pressures were recorded at seven standardized surgical time points. Postoperative pain (UNESP-Botucatu multidimensional composite pain scale) and sedation were assessed up to 6\u2009h after surgery; methadone (0.25\u2009mg\/kg IM) was administered as rescue analgesia when indicated.
