2. Figure 1
Median (minimum–maximum) pain scores in dogs before (Preop) and after surgery. Dogs either received epidural anesthesia and analgesia (EPID; Preop n = 10, thereafter n = 9) or combined femoral and sciatic nerve blocks (F + S; n = 10). Post operative assessment times are relative to the time that the orotracheal tube was removed. Higher values indicate greater pain.

3. Figure 2
Median (minimum–maximum) sedation scores in dogs before (Preop) and after surgery. Dogs either received epidural anesthesia and analgesia (EPID; Preop n = 10, thereafter n = 9) or combined femoral and sciatic nerve blocks (F + S; n = 10). Post operative assessment times are relative to the time that the orotracheal tube was removed. Higher values indicate greater sedation.

4. Figure 3
Cumulative fraction (%) of dogs that had received at least one dose of hydromorphone (0.05 mg kg−1) by the end of each assessment time. Assessment times are relative to the time that the orotracheal tube was removed postoperatively. Dogs either received epidural anesthesia and analgesia (EPID; n = 9) or combined femoral and sciatic nerve blocks (F + S; n = 10). Numbers in parentheses are the number of dogs that received a second dose of hydromorphone by the end of each assessment time. *A third dose was given to two dogs at this assessment time.

5. Figure 4
Cumulative total hydromorphone (mg kg−1) administered to dogs over the 24 hour period after the orotracheal tube was removed. Dogs either received epidural anesthesia and analgesia (EPID; n = 9) or combined femoral and sciatic nerve blocks (F + S; n = 10).
