The authors evaluated the effects of locally anesthetizing the sciatic and femoral nerves in sheep undergoing stifle (femorotibial) surgery (16 sheep received nerve blocks; 16 sheep underwent a nerve localization procedure but received no nerve blocks). Heart rate, mean arterial blood pressure and end-tidal isoflurane were recorded every 5 min while sheep were anesthetized. At some of the observed time points, the mean heart rate in the sheep that had received no nerve blocks was significantly higher than in the sheep that had received the nerve blocks. Postoperatively, each sheep was assigned scores for comfort and attitude, movement, flock behavior, feeding behavior and appetite and respiratory rate (based on predefined descriptions). Though the authors found no undesirable effects of this local anesthesia, beneficial effects of the nerve blocks were minimal or not readily apparent under the conditions of this study.
