“…Using a previously described technique, 5 mL of LA was injected in the intermuscular plane between the sternocleidomastoid and scalene muscles at the level of the thyroid cartilage. 7,8 In the ISB group, the US transducer was applied in a sterile fashion on the lateral side of the neck at the level of the cricoid cartilage in order to obtain a view of the 3 hypoechoic structures, which represent the roots/trunks of the brachial plexus. 9 A skin wheal was raised with 3 mL of lidocaine 1%.…”

“…In human medicine, ultrasound guidance is considered to reduce the risks of the procedure and to increase the operator's confidence and it is routinely used for a large number of technically difficult or risky procedures in anaesthesiology for CSF punctures, vessel cannulations, and nerve blocks . Impact and usefulness of ultrasound guidance has been compared to landmark techniques for different procedures in human medicine with positive or rather mixed results . In veterinary medicine, a direct ultrasound‐guided technique for lumbar puncture has been described in dogs .…”

The standard technique for placing a needle into the canine lumbar subarachnoid space is primarily based on palpation of anatomic landmarks and use of probing movements of the needle, however, this technique can be challenging for novice operators. The aim of the current observational, prospective, ex vivo, feasibility study was to compare ultrasound-guided vs. standard anatomic landmark approaches for novices performing needle placement into the lumbar subarachnoid space using dog cadavers. Eight experienced operators validated the canine cadaver model as usable for training landmark and ultrasound-guided needle placement into the lumbar subarachnoid space based on realistic anatomy and tissue consistency. With informed consent, 67 final year veterinary students were prospectively enrolled in the study. Students had no prior experience in needle placement into the lumbar subarachnoid space or use of ultrasound. Each student received a short theoretical training about each technique before the trial and then attempted blind landmark-guided and ultrasound-guided techniques on randomized canine cadavers. After having performed both procedures, the operators completed a self-evaluation questionnaire about their performance and self-confidence. Total success rates for students were 48% and 77% for the landmark- and ultrasound-guided techniques, respectively. Ultrasound guidance significantly increased total success rate when compared to the landmark-guided technique and significantly reduced the number of attempts. With ultrasound guidance self-confidence was improved, without bringing any significant change in duration of the needle placement procedure. Findings indicated that use of ultrasound guidance and cadavers are feasible methods for training novice operators in needle placement into the canine lumbar subarachnoid space.

“…[131415] Nerve stimulation techniques rely on the needle tip being directed towards the nerve itself and are particularly useful when a nerve is difficult to image sonographically. The ON is one such nerve that can be both, difficult to stimulate electrically and image sonographically.…”

Obturator nerve block in transurethral resection of bladder tumor: A comparison of ultrasound-guided technique versus ultrasound with nerve stimulation technique

Background:Obturator nerve (ON) stimulation during transurethral resection of lateral and posterolateral bladder wall tumor under spinal anesthesia may lead to obturator reflex, adductor contraction, and leg jerking with complications such as bleeding, bladder perforation, or incomplete tumor resection. Our study was carried out to obtain successful block of ON using ultrasound (US)-guided technique with or without nerve stimulation in patients undergoing transurethral resection of bladder tumor (TURBT) under spinal anesthesia.Aims:The aim of the study was to compare the effectiveness of two different techniques in blocking ON and adductor spasm during TURBT.Settings and Design:Prospective, randomized, double-blind study.Subjects and Methods:Sixty patients with American Society of Anesthesiologists Status II and III scheduled to undergo TURBT for lateral and posterolateral bladder wall tumor were enrolled. Group I (US group, n = 30) patients received 5 ml of bupivacaine 0.5% each at anterior, and posterior division of ON under real-time US visualization and Group II (US-NS group, n = 30) received the same amount of bupivacaine 0.5% for each division using US-guidance with nerve stimulation-assisted technique. Motor block onset time, block success and performance time, ease of performance of block, and complications were measured besides assessing patient and surgeon satisfaction into two groups.Statistical Methods Used:SPSS using two sample independent t-test and Pearson's Chi-square/Fisher's exact test.Results:Motor block onset was significantly faster in Group II (6.67 ± 2.40) than in Group I (12.39 ± 2.55). A success rate of 90% was achieved in Group II as compared to 76.7% in Group I with increased block performance time in Group II (4.47 ± 0.73 min) versus (2.10 ± 0.51 min) in Group I. A better patient and surgeon satisfaction were seen in Group II with combination of US and nerve stimulation technique. No complications were encountered.Conclusion:We conclude that both techniques are safe and easy to perform; however, nerve stimulation as an adjunct to US results in a faster onset of block with a higher success rate.

A Randomized Comparison Between Ultrasound-Guided and Landmark-Based Superficial Cervical Plexus Block

Abstract: Ultrasound guidance does not increase the success rate of superficial cervical plexus block compared with a landmark-based technique. Additional confirmatory trials are required.
