In the present study the comprisal of brachial plexus and nerves springing from the brachial plexus in Günther’s vole has been determined. Ten adult voles (five males and five females) were used in this study. Nerves comprising the brachial plexus and the nerves arising from brachial plexus in vole were dissected and the findings were saved. The brachial plexus of the vole was comprised of the ventral root of cervical (C) 5th, 6th, 7th and 8th and thoracic (T) 1st spinal nerves. Also, the brachial plexus was consisted of three trunks including cranial (C5th and C6th), medial (C7th) and caudal (C8th and T1st) trunks. Nervus (n.) subclavius, n. suprascapularis, nervi (nn.) subscapularis, n. axillaris, n. musculocutaneus, n. thoracodorsalis, nn. pectorales craniales, n. pectorales caudales, n. thoracicus lateralis, n. thoracicus longus, n. ulnaris, n. medianus, and n. radialis were determined to be arising from brachial plexus. In conclusion, macroanatomical features of brachial plexus and its branches in Günther’s vole have been determined. It is thought that the findings will contribute to neuroanatomy of the rodents.

This blinded, randomized experimental study was designed to evaluate the analgesic effects of adding epinephrine or xylazine to lidocaine solution for brachial plexus block (BPB) in sheep. Nine healthy, fat-tailed female lambs (26.6 ± 1.5 kg) were randomly allocated into three groups: lidocaine 2%, 5 mg kg-1 (LID, n = 6), lidocaine (5 mg kg-1) with epinephrine 5 µg mL-1 (LIDEP, n = 6) or lidocaine (5 mg kg-1) with xylazine 0.05 mg kg-1 (LIDXY, n = 6). Each animal was tested twice. The sheep received a total volume of 0.25 mL kg-1 for BPB. A nerve stimulator was used to locate the nerves of the brachial plexus. Onset and duration of analgesia of the forelimb were evaluated using superficial and deep pin prick and pinching of skin with a hemostat clamp. Heart and respiratory rates, and rectal temperature were recorded before and at predetermined intervals following the completion of the block. Brachial administration of LID, LIDEP or LIDXY produced forelimb analgesia within 11.3, 11.0 and 7.0 minutes, respectively. The mean duration of analgesia was 100.0 min in LID and 133.2 min in LIDEP group. The mean duration of analgesia in LIDXY group (186.8 min) was significantly longer compared with LID group. In LIDEP group a significant increase in heart rate occurred 5 min after drug administration. Heart rate decreased from 35 to 80 minin sheep received LIDXY. In conclusion, the addition of xylazine to lidocaine solution for BBP provided a prolonged duration of action without any adverse effects in fat-tailed sheep.
