“…The number of studies in large animals and in cattle in particular has also increased. There are studies published describing ultrasound‐guided paravertebral blocks (Kramer and others 2014), brachial plexus blocks (Iwamoto and others 2012) and sciatic and femoral nerve blocks in farm animals (Adami and others 2011, Wagner and others 2011, d'Ovidio and others 2014, Waag and others 2014). However, there is still a lack of case reports or studies describing the use of these techniques in calves in a clinical scenario.…”

A two-day-old heifer calf presented with a non-weight bearing right hindlimb lameness following a traumatic event. A closed, complete, overriding, displaced fracture of the distal right metatarsal diaphysis was diagnosed and closed reduction and cast placement was elected as treatment. The calf was sedated intravenously with a combination of diazepam and ketamine. With the calf in lateral recumbency, sciatic and femoral nerve blocks were performed using procaine to provide analgesia and muscle relaxation for the procedure. The procedure was performed with the patient sedated and no further anaesthetics or analgesics were needed. This report is the first describing the use of sciatic and femoral nerve blocks as analgesia for a young calf. The success of the technique allowed a decrease in the dosage of other systemic drugs. This is an important factor in decreasing potential complications related to anaesthesia in these patients.

“…Studies in human medicine have shown an increased success rate when sonographic guidance was used for the performance of the peripheral nerve blocks [ 42 ]. The study from Waag et al provided a detailed anatomical description of the sciatic and the femoral nerves [ 30 ]. In the present study, only one sheep received rescue analgesia intraoperatively, leading to the assumption that the applied technique was adequate and the success rate was nearly 100%.…”

“…With this technique loss of sensation as well as motor function are confined to the operated limb and a combined block of the sciatic and the femoral nerves might lead to profound peri-operative analgesia while standing ability is maintained on three limbs. The most simple technique to apply sciatic–femoral–nerve blocks is the use of anatomical landmarks [ 19 , 30 ]. Nerve stimulators (NS) have been used to improve the success rate of peripheral nerve blocks due to the possibility to localize the nerve through an appropriate motor response.…”

Peripheral nerve blocks are commonly used in human and veterinary medicine. The aim of the study was to compare the analgesic efficacy of a combined block of the femoral and sciatic nerves with an epidural injection of ropivacaine in experimental sheep undergoing orthopaedic hind limb surgery. Twenty-five sheep were assigned to two groups (peripheral nerve block; sciatic and femoral nerves (P); epidural analgesia (E)). In group P 10 mL ropivacaine 0.5% was injected around the sciatic and the femoral nerves under sonographic guidance and 10 mL NaCl 0.9% into the epidural space while in group E 10 mL ropivacaine 0.5% was injected into the epidural space and 10 mL NaCl 0.9% to the sciatic and the femoral nerves. During surgery, heart rate, respiratory rate and mean blood pressure were used as indicators of nociception. In the postoperative phase, nociception was evaluated every hour by use of a purposefully adapted pain score until the animal showed painful sensation at the surgical site. The mean duration of analgesia at the surgical wound was 6 h in group P and 8 h in group E. Mean time to standing was 4 h in group P and 7 h in group E. In conclusion time to standing was significantly shorter in group P while the duration of nociception was comparable in both groups. The peripheral nerve block can be used as an alternative to epidural analgesia in experimental sheep.

“…These techniques do not only decrease general anesthesia drawbacks but they also lead to effective analgesia (6)(7)(8). In animals many surgical operations especially in the distal parts of the limbs can be performed under peripheral nerve block such as sciatic and femoral nerves block of the pelvic limbs in cattle, sheep and dogs (9)(10)(11) and brachial plexus nerve block in the forelimbs in cattle, dogs and cats (3,5,7,9).…”

This study was conducted to describe and evaluate the ultrasound-guided technique and the anatomical relation for brachial plexus block in donkeys. In the first study, three donkey's cadavers were used to determine the neuroanatomical description of the brachial plexus. In the second study, four donkeys were used to evaluate the ultrasound structure of brachial plexus and the distribution of methylene blue solution that was injected around the nerves during subsequent postmortem anatomical dissection. In the third study, six donkeys were used to evaluate the efficient of the ultrasound-guided brachial plexus block after injection of lidocaine. Ultrasound was used to identify brachial plexus and blood vessels. Anatomical scrutiny assured the relationship between the nerves and the blood vessels. The nerves were adequately stained with methylene blue solution in all donkeys. A volume of 25 mL of lidocaine per injection site resulted in effective sensitive and motor block of forelimbs nerves after brachial plexus block. Based on the obtained data we could conclude that brachial plexus nerve block guided by ultrasound can be used in surgery of donkey distal fore limb.
