“…Use of ultrasound for performing peripheral nerve blocks has been investigated and used in people for over 20 years and is becoming increasingly popular for facilitating various regional anesthetic techniques and peripheral nerve blocks in small animals [ 5 – 12 , 14 – 17 ]. Ultrasound offers several advantages over blind and nerve stimulator-guided approaches, including the ability to visualize the procedure in real time while identifying the target nerve and manipulating the needle relative to the nerve and other important anatomical structures [ 5 – 8 , 15 – 17 ].…”

Peripheral nerve blocks are becoming increasingly popular for perioperative use as anesthetics and analgesics in small animals. This prospective study was performed to investigate the duration of motor and sensory blockade following use of bupivacaine for ultrasound-guided femoral and sciatic nerve blocks in dogs and to measure the plasma concentrations of bupivacaine that result from these procedures. Six dogs were anesthetized twice using a randomized cross-over design. At the first anesthetic, dogs were assigned to receive either an ultrasound-guided femoral nerve block or sciatic nerve block with 0.15 mL kg-1 of bupivacaine 0.5%. Two months later, the other nerve block was performed during a second anesthetic. At 5, 10, 15, 20, 30 and 60 minutes after injection, arterial blood samples were collected for laboratory measurement of bupivacaine. After 60 minutes, dogs were recovered from anesthesia. Starting at two hours post-injection, video-recordings of the dogs were made every two hours for 24 hours. The videos were randomized and the degree of motor and sensory blockade was evaluated using a three-point scoring system (0 = no effect, 1 = mild effect, 2 = complete blockade) by two blinded assessors. The median (range) times to full recovery from motor blockade were 11 (6–14) hours (femoral) and 12 (4–18) hours (sciatic), and 15 (10–18) hours (femoral) and 10 (4–12) hours (sciatic) for sensory blockade. There were no differences in the median times to functional recovery for the two techniques. Plasma concentrations of bupivacaine were no different following the blocks and were less than 0.78 μg mL-1 at all times. These results suggest that these ultrasound-guided nerve blocks do not result in potentially toxic systemic levels of local anesthetic and that their duration of action is useful for providing anesthesia and analgesia for pelvic limb procedures.

“…11,[14][15][16][17]19,[23][24][25][26] Radiographs are unlikely to show evidence for iliopsoas strain, although they may detect mineralisation of the tendinous attachments, or enthesiophytosis, which has been seen with some instances of fibrotic myopathy and other chronic injuries. 11 Computer tomography (CT) evaluation for acute iliopsoas strain has been previously described and found to be accurate for assessing intramuscular oedema and inflammation.…”

Objective:Iliopsoas injury and strain is a commonly diagnosed disease process, especially amongst working and sporting canines. There has been very little published literature regarding iliopsoas injuries and there is no information regarding the ultrasound evaluation of abnormal iliopsoas muscles. This manuscript is intended to describe the ultrasound findings in 73 canine agility athletes who had physical examination findings consistent with iliopsoas discomfort. The population was chosen given the high incidence of these animals for the development of iliopsoas injury; likely due to repetitive stress. Methods:Medical records of 73 agility performance canines that underwent musculoskeletal ultrasound evaluation of bilateral iliopsoas muscle groups were retrospectively reviewed. Data included signalment, previous radiographic findings, and ultrasound findings. A 3-tier grading scheme for acute strains was used while the practitioner also evaluated for evidence of chronic injury and bursitis. Results:The majority of pathologies were localised to the tendon of insertion, with the majority being low grade I-II strains (80.8%). Tendon fibre disruption (71.2%) and indistinct hypoechoic lesions (91.8%) were the most common of acute changes noted. Hyperechoic chronic changes were noted in 84.9 percent of cases. Acute and chronic changes were commonly seen together (62.8%). Conclusion:Diagnostic musculoskeletal ultrasound was used to identify lesions of the iliopsoas tendon consistent with acute and chronic injury, as well as identifying the region of pathology. The majority of agility performance dogs had low grade acute strains based on the tiered system, with mixed acute and chronic lesions being noted frequently. Application:Diagnostic musculoskeletal ultrasound provides a non-invasive diagnostic modality for patients suspected of having an iliopsoas strain.

“…Em gatos, diferentes técnicas de anestesia regional como bloqueio de plexo braquial, bloqueio do plexo lombar, entre outros foram recentemente estudados (MOSING et al, 2010;HARO et al, 2012HARO et al, , 2015 ). Porém, o conhecimento atual sobre a anatomia e distribuição de um injetado após os bloqueios dos nervos ciático e femoral baseia-se em estudos anatômicos em cadáveres e tomografia, com uso de corantes ou de contraste iodado (HARO et al, 2012(HARO et al, , 2013MOGICATO et al, 2015).…”
