“…Published normative physiological data for anesthetized SM is scarce, and for this reason Table 1 lists the physiological data (mean, standard deviation) recorded over five typical scan sessions. In the awake restrained SM, body temperature is 37-39 • C (Brady, 2000;Pinneo, 1968), mean arterial blood pressure is 140 ± 4 mmHg (Byrd & Gonzalez, 1981), and the heart rate may exceed 300 beats per minute (Pinneo, 1968). As Table 1 indicates, isoflurane anesthesia decreases body temperature, blood pressure and heart rate.…”
