“…As a result, for procedures below the knee, the nerve should be blocked wherever it is best seen. When visualization is difficult, nerve stimulation helps confirm that the structure in question is indeed the SN rather than tendon or muscle (47).…”

“…Because of these advantages, we decided to use a sophisticated technique of US-guided regional anesthesia and compared with traditional SA, which had not been done yet. We performed popliteal block in the upper level of the popliteal fossa because the ultrasonic identifi cation of the sciatic nerve at the mid thigh level in one-third of patients required NS to confi rm its sonographic appearance [5].…”

“…Recent studies have considered various types of regional anesthesia regarding same levels of anesthesia and better postoperative analgesia for patients scheduled for ankle surgery [3]. Ultrasound (US)-guided regional anesthesia has gained popularity as an addition to the nerve stimulation (NS) technique, but is also becoming a self-suffi cient technique [4][5][6]. US and NS-guided blocks of the sciatic nerve facilitate a more accurate nerve localization and precise application of the local anesthetic (LA) [7].…”

“…Sciatic blocks were performed at the level of the distal thigh with the patient in the prone position [13][14][15] . The probe was placed just cephalad of the popliteal crease with proximal scanning until the best image of the sciatic nerve was obtained proximal to the tibial/common peroneal bifurcation.…”

“…In-plane needle imaging was used from the right side of the patient's bed (right leg, medial to lateral and left leg, lateral to medial). Concomitant neurostimulation was used depending on the quality of the ultrasound images obtained 13 but ultimately in all patients the needle was repositioned as necessary to surround the sciatic nerve with 20 ml ropivacaine (ACLR=0.375%, TKJR=0.5%).…”

Needle-nerve stimulation has a false negative motor response rate, which may increase needle passes. This prospective, randomised study tested the hypothesis that femoral nerve catheters placed with ultrasound-only guidance could provide comparable postoperative analgesia to those placed using a conventional nerve stimulation endpoint. Patients presenting for major knee surgery to the lead investigator were recruited. Needles introduced for femoral nerve catheter placement were initially guided with 'oblique' out-of-plane ultrasound imaging but were then prospectively randomised to either an ultrasound (n=21) or nerve stimulation (n=24) endpoint. An elastomeric infusion of ropivacaine 0.2% 2 ml/hour with as required hourly 5 ml boluses was continued for >48 hours in hospital and/or in the home. Needle time under the skin and numerical rating pain score during insertion were recorded. Patients were questioned for worst numerical rating pain score, the need for supplementary ropivacaine boluses and tramadol on postoperative days one and two. There was no difference in the worst numerical rating pain score at rest and on movement and the requirement for supplementary ropivacaine boluses or tramadol during the first 48 postoperative hours. The median (quartiles) needle time under the skin was 58 seconds (51 to 76) in the ultrasound group and 120 seconds (95 to 178) in the nerve stimulation group (P=0.001). The median (quartiles) insertion numerical rating pain score was 2 (0 to 2) in the ultrasound group and 4 (2 to 6) in the nerve stimulation group (P=0.014). Femoral nerve catheters placed for major knee surgery using an ultrasound endpoint provided postoperative analgesia comparable to that obtained when using a nerve stimulation endpoint and were associated with a reduction in both needle manipulations and procedure-related pain.
