“…There have been several reports on BPB using a nerve stimulator in small animals [8,22,23]. However, as these studies did not compare blocking effects with or without a nerve stimulator, the usefulness of nerve stimulators has not been demonstrated.…”

“…Furthermore, these acataleptic effects preclude the comparison of pharmacological potency between anesthetics. Several reports have described the use of nerve stimulators to locate the brachial plexus, and this approach has significantly improved the attainment of regional blocks in dogs [8,22]. Therefore, we assumed that these technical improvements would enable the accurate comparison of pharmacological potency between anesthetics in specific regional anesthesia.…”

ABSTRACT. In the present study, the efficacy of a nerve stimulator in performing brachial plexus block (BPB) in dogs was investigated. The nerve blocking effects of bupivacaine and ropivacaine for BPB were also compared. Twelve beagles were allocated to groups based on the following treatments: conventional BPB with 0.5% bupivacaine (0.5% BupiM group) or BPB with 0.5% bupivacaine, 0.5% ropivacaine or 0.75% ropivacaine and a nerve stimulator (the 0.5% BupiS, 0.5% RopiS and 0.75% RopiS groups, respectively). After BPB, nerve blocking effects were assessed based on sensory blockade in several cutaneous areas and knuckling. The ratio of full block (blockade in all cutaneous areas) for 0.5% BupiM was 25%, and that for 0.5% BupiS was significantly higher, 75% (p<0.05). For the 0.5% BupiS, 0.5% RopiS and 0.75% RopiS groups, the average duration of full block was 387, 184 and 275 min, respectively, and the average duration of knuckling was 703, 460 and 421 min, respectively. The duration of full block and knuckling for the two ropivacaine groups was shorter compared with that of the 0.5% BupiS group. In conclusion, when using bupivacaine and ropivacaine for BPB in dogs, it is worth noting that there are differences in onset time and duration and that effective perioperative analgesia can be achieved depending on the intended use.KEY WORDS: brachial plexus block, bupivacaine, canine, nerve stimulator, ropivacaine.

“…Was found a variation in the anesthesia period between both techniques. The BPB anesthetize the blocked member for a long time about 8.3 h similar to another study which used multiple injections in dogs with 0.375% bupivacaine with vasoconstrictor (4mg/kg) got an 11 h analgesic period 12 . In this sense, a study aiming a long duration anesthesia comparing 0.5% ropivacaine and 0.5% bupivacaine in plexus brachial block in humans do not found significant difference in relation the beginning and duration of the anesthesia between the two treatments (7.1 and 11.5 h, respectively) 16 .…”

“…Moreover, the use of the tourniquet showed to be painful, what can be avoided using lidocaine local infiltration previously in the place where the tourniquet will be fixed 11 . To facilitate the technique in BPB, was utilized an electrical nerve stimulation to localize the nerves which compose the brachial plexus 2,3 , however we can find other technique used for this aim, for instance the multiple injections and the use of an electrical nerve stimulation in dogs 12,13 , catheter with a tube in dogs 14 and the utilization of an inserted cannula (30º in relation to the skin) in the axillary region direction was used in children 15 . By the way, in plexus brachial block in the most part of these researches is used the localization of the axillary artery 2,12,15 .…”

PURPOSE: To evaluate the effects of bupivacaine 0.5 and 0.25% in intravenous regional anesthesia (IVRA) and brachial plexus block (BPB), respectively, on anesthesia, motor block and cardiovascular parameters in dogs. METHODS: Fourteen healthy adult dogs averaging 10 kilograms (kg) of body weight. Animals were randomly assigned to receive one of the two treatments IVRA (n=7) or BPB (n=7). All the animals were sedated with acepromazine (0.1 mg/kg intramuscular). To execute the BPB was used an electrical nerve stimulation. Anesthesia, motor block, sedation, cardiovascular and respiratory effects were measured as effect of the treatment. RESULTS: BPA showed superior efficiency and duration of anesthesia (BPB - 456 ± 94 minutes vs IVRA - 138 ± 44) as well as motor block. There only physiologic parameter which change were the systolic pressure in BPB and respiratory rate for both treatments. CONCLUSION: In dogs the 0.25 % hyperbaric bupivacaine in BPB produces a front limb anesthesia about three times more than the 0.5 % in IVRA, with ptosis of the limb blocked and little interference in the cardiovascular system but with decrease in respiratory rate.

“…Sometimes, it may cause death due to proper treatment and wrong treatment for lacking of the knowledge of nerve innervations to the wing of a bird. Anatomic knowledge of neuronal pathways and their landmarks have been used for many regional anesthetic techniques in mammals (Futema et al, 2002). Regional anesthetic techniques provide anesthesia to a restricted portion of the body while leaving physiologic functions and metabolism intact.…”

The injury to the peripheral nervous system is common clinical problem especially injury to the wing is the most common in birds. The present study aimed to document the detailed features of the morphological structure and the innervations areas of the brachial plexus in indigenous duck (Anas platyrhynchos domesticus). A total of six mature indigenous ducks (three of them were male and three were female) were used in this study. After administering an anesthetic to the birds, the body cavities were opened. The birds were fixed with formaldehyde after draining of the blood. The nerves of the brachial plexus were dissected separately and photographed. The brachial plexus was formed by the union of the ventral branches of 14 th and 15 th cervical spinal nerve and 1 st , 2 nd and 3 rd thoracic spinal nerves, which were confirmed by palpation and counting the cervical vertebrae. Present study revealed that few small and large branches originated from brachial plexus and innervated into the specific muscles and their adjacent structure. Five nerve roots formed three nerve trunks in the duck, which constitute the dorsal and ventral cords. The pectoral trunk and median-ulnar nerve originated from ventral cord, while dorsal cord gives axillary nerve continued as a radial nerve into the wing of duck. The axillary nerve innervated into to skin of the dorsal side of the wing and shoulder deltoideous muscles, coracobrachialis muscles and propatagiasis cervical muscles. The radial nerve innervated to the humuro-brachial and triceps muscles, extensor carpi radial and supinator muscles. The ulnar nerve innervated extensor aspect of joint, flexor carpi ulnar muscles and superficial flexor muscle. The median nerve innervated into the median surface of the brachial and metacarpal region, flexor carpi radial muscle, pronator teres muscles, superficial and profound digital flexor muscles. The general macroanatomical shape of the brachial plexus and the distribution of the nerves originating from this plexus displayed some differences from other birds.
