  1. Data are presented as mean ± SD
  2. Horses were maintained with sevoflurane and CRI of either medetomidine (3.0 μg/kg/h) (Group M; n = 10); or medetomidine (3.0 μg/kg/h) and propofol (3.0 mg/kg/h) (Group MP3; n = 10); or medetomidine (3.0 μg/kg/h) and propofol (6.0 mg/kg/h) (Group MP6; n = 10)
  3. None of the data across rows differed significantly from each other
  4. HR heart rate, SAP systolic arterial blood pressure, DAP diastolic arterial blood pressure, MAP mean arterial blood pressure
