Table 2 The mean ± standard deviation of HR (beat/ min), RR (breath/ min) and RT (°C) measured at different times 10 minutes prior- and 10, 20, 30, 45, 60, 75, and 90 minutes post- the epidural analgesia in rabbits. Group A: lidocaine epidural, group B: tramadol epidural, and group C: lidocaine-tramadol epidural
