Anesthesia GA ± adductor canal block Spinal ± sedation Antibiotics Surgery High volume LA infiltration Surgical time <120 minutes Haemostasis, etc. • Local anesthetic: 5–10 mL. Spread of local anesthetic within adductor canal to peroneal and tibial nerves is described in literature. At the ankle, branches of the saphenous nerve are located medially, next to the subcutaneously positioned saphenous vein. A total of 42 patients, American Society of Anesthesiologists I/II scheduled for knee arthroscopy under spinal anesthesia scheduled to receive adductor canal block, were randomized into two groups: group N received 20 mL of ropivacaine 0.375% and group H received 40 mL. -, Tan Z, Kang P, Pei F, Shen B, Zhou Z, Yang J. When attempting to identify the saphenous nerve on US image, the following anatomical considerations should be kept in mind: The saphenous nerve block results in anesthesia of the skin on the medial leg and foot (Figure 5). 2019;32:30–8. Editor—I read with interest the recent article by Jaeger and colleagues, 1 in which the authors describe the minimal effective volume to fill the distal aspect of the adductor canal with local anaesthetic. The adductor canal (canalis adductorius, Hunter's canal, subsartorial canal) is a musculoaponeurotic tunnel in the middle third of the thigh, extending from the distal apex of the femoral triangle—defined by the crossing of the medial margin of the adductor longus muscle and the medial margin of the sartorius muscle—to the adductor hiatus, an opening in the adductor magnus [1, 2]. Found inside – Page 279... possible complications Both sensory and motor complications have been reported after high-volume adductor canal block. Fig. 12. Adductor canal block. Several approaches have been described to nerve block the saphenous nerve along its route from the inguinal area to the medial malleolus (Figure 2). Jæger P, Koscielniak-Nielsen ZJ, Hilsted KL, Grevstad U, Siersma V, Fabritius ML, Dahl JB. "--Doody's Review Service Authored by the world's leading authorities, this is an authoritative, full-color instructional manual for mastering nerve block techniques. Knee Surg Sports Traumatol Arthrosc. Once the femoral artery has been identified, the probe is moved distally to trace the artery until it passes through the adductor hiatus to become the popliteal artery. Background: Theoretically, the ideal volume of local anaesthetic for adductor canal block (ACB) would ensure sufficient filling of the canal and avoid proximal spread to the femoral triangle.

Is useful after lower limb, foot and ankle surgery (usually in combination with a popliteal block). A prospective, randomized comparison between single- and multiple-injection techniques for ultrasound-guided subgluteal sciatic nerve block. 2016 Oct;123(4):1026-32. doi: 10.1213/ANE.0000000000001517. Proximal spread to the femoral triangle was seen in 0/4 (0%), 7/12 (58%), 4/8 (50%), and 8/16 (50%) subjects with the 5, 10, 15, and 20 ml doses, respectively (P=0.25). Sciatic nerve block via posterior Labat approach is more efficient than lateral popliteal approach using a double-injection technique: a prospective, randomized comparison. -, Karkhur Y, Mahajan R, Kakralia A, Pandey AP, Kapoor MC. saphenous nerve block within and distal to the adductor canal with low volume of local anesthetic Areti Adoni, Tilemachos Paraskeuopoulos, Theodosios Saranteas, Tatiana Sidiropoulou, We evaluated sensory motor blocks of both peroneal and tibial nerves at 30 and 60 min. Reg Anesth Pain Med. Patient education and assistance with ambulation should be encouraged. Clipboard, Search History, and several other advanced features are temporarily unavailable. This book is a technique-oriented guide, which introduces the use of ultrasound technology with practical instruction in the placement of peripheral nerve blocks and continuous perineural catheters. Administration of 5–10 mL of local anesthetic next to the artery in the plane between the sartorius and vastus medialis muscles should suffice without confirming nerve position. Ultrasound machine with a linear transducer (8–14 MHz), sterile sleeve, and gel, One 10-mL syringe containing local anesthetic, Peripheral nerve stimulator to elicit paresthesia. Bethesda, MD 20894, Copyright Epub 2021 May 29. Accessibility This may be useful for post-operative analgesia after knee, foot or ankle surgery (usually in combination with a popliteal block).

The main mechanism of analgesia involved in adductor canal blocks probably ... The femoral vein accompanies the artery and saphenous nerve, which all can be identified at a depth of 2–3 cm (Figure 3). Adductor canal block (ACB) has recently emerged as an alternative to femoral nerve block for pain control after various knee procedures especially knee arthroplasty. Thomas F. Bendtsen, Ana M. Lopez, and Thomas B. Clark, • Indications: saphenous vein stripping or harvesting; supplementation for medial foot/ankle surgery in combination with a sciatic nerve block, and analgesia for knee surgery in combination with multimodal analgesia. except for the last block, which only con-tained five numbers. 2016. Chen J, Lesser JB, Hadzic A, Reiss W, Resta-Flarer F. Adductor canal block can result in motor block of the quadriceps muscle. This study aimed at investigating possible landmarks making it feasible to perform ACB intraoperatively. Found inside – Page 1646.3).36 Depending upon the nerve block, these nerves, usually both of them, must be resected ... 6.12 The adductor canal should contain the saphenous nerve. Recently, adductor canal blockade has gained popularity as it is reported to provide analgesia to the anterior knee without resulting in significant quadriceps muscle weakness. For that reason, it is recommended to perform this nerve block as distally as practically possible. FOIA 2020 Jan-Mar;14(1):33-37. doi: 10.4103/sja.SJA_410_19. Disclaimer, National Library of Medicine † Adductor canal block (ACB) may provide good analgesia without reduced power after knee surgery. These L2 through L-4 nerves join together as a structure known as the lumbar plexus. Volumes were assigned sequentially to the subjects using the continual reassessment method followed by Bayesian analysis to determine the ED95. The rescue analgesic requirement was similar in all groups.Conclusions:While ACB performed with concentrations of 0.25% and 0.16% bupivacaine in the same volume have the similar effect, they improve analgesia quality in patients undergoing ... The saphenous nerve is typically imaged by ultrasound as a small, round, hyperechoic structure anterior to the artery. 2021 Feb 13;11(1):e110904. Grevstad U, Jæger P, Sørensen JK, Gottschau B, Ilfeld B, Ballegaard M, Hagelskjaer M, Dahl JB. doi: 10.1016/j.bja.2019.04.053. Methods: The criterion for successful ACB was the loss of pinprick sensation … Ultrasound-guided adductor canal block versus combined adductor canal and infiltration between the popliteal artery and the posterior capsule of the knee block for osteoarthritis knee pain. • Goal: local anesthetic spread lateral to the femoral artery and deep to the sartorius muscle or more distal, below the knee, adjacent to the saphenous vein. 1 compare the motor and analgesic effects of adductor canal block (ACB) and femoral nerve block (FNB) for total knee arthroplasty (TKA) in the context of an established clinical pathway using multimodal analgesia.

The borders of the adductor canal are dense, and higher injection volumes are ... The relevant anatomy for the adductor canal block focuses on the specific target of the saphenous nerve. The adductor canal block, a primarily sensory block, may offer a favorable alternative to the continuous femoral nerve block as quadriceps function is largely preserved.6 Preliminary studies of continuous adductor canal blocks for postoperative analgesia after total knee arthroplasty are encouraging.7-9 Anatomically, this block is performed along Taboada Muñiz M, áLvarez J, Cortés J, Rodrguez J, Atanassoff PG. 3 The saphenous nerve is the longest cutaneous branch of the femoral nerve. .
