Peripheral nerve blocks are effective in treating acute pain, thereby minimizing the requirement for opiate analgesics. Fractured neck of femur (FNF) is a common, painful injury. The provision of effective analgesia to this cohort is challenging but an important determinant of their functional outcome. We investigated the analgesic efficacy of continuous femoral nerve block (CFNB) in patients with FNF. Following institutional ethical approval and with informed consent, patients awaiting FNF surgery were randomly allocated to receive either standard opiate-based analgesia (Group 1) or a femoral perineural catheter (Group 2). Patients in Group 1 received parenteral morphine as required. Those in Group 2 received a CFNB comprising a bolus of local anaesthetic followed by a continuous infusion of 0.25% bupivacaine. For both Groups, rescue analgesia consisted of intramuscular morphine as required and all patients received paracetamol regularly. Pain was assessed using a visual analogue scale at rest and

This is a retrospective review to evaluate the efficacy of femoral nerve block in providing analgesia following reconstructive surgery of the knee and to compare the postoperative course of patients who received femoral nerve block with a retrospective cohort who were cared for prior to the institution of a regional anesthesia program. The investigators hypothesize that femoral nerve blockade limits postoperative opioid needs, improves analgesia and facilitates discharge home when compared to intravenous opioid use following reconstructive knee surgery ...
A femoral nerve block is a nerve block that uses local anesthetic to achieve analgesia in the leg. The block works by affecting the femoral nerve. A femoral nerve block results in anesthesia of the skin and muscles of the anterior thigh and most of the femur and knee joint, as well as the skin on the medial aspect of the leg below the knee joint . The block can be performed using anatomical landmarks, ultrasound or a nerve stimulator. Fascia iliaca block https://www.nysora.com/femoral-nerve- ...
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. ...

In fact, data from the only study of perineural infusion that varied both the infusion rate and concentration in a static ratio so that the total dose was comparable in each treatment group suggests that local anesthetic concentration and volume (rate) do not influence block effects as long as the total dose remains constant.13 These results, though, were based exclusively on continuous posterior lumbar plexus catheters, and therefore may not be applicable to femoral infusion because local anesthetic pharmacodynamics vary considerably among anatomic catheter sites. For example, increasing local anesthetic concentration has differing effects on the incidence of an insensate extremity depending upon catheter site location: increased for infraclavicular,14 decreased for popliteal,15 no difference for axillary,16 and variable for interscalene.8,17,18 Considering cFNB is often provided for analgesia following major surgical procedures of the knee in elderly patients, and a fall in this patient ...
Major surgical types for knee included arthroscopy, total or partial knee arthroplastic surgery. These procedures are typically associated with severe pain. Function training, which is imperative after surgery for these patients, also aggravated pain.Post-operative pain after major knee surgery impaired post-operative knee recovery and prolonged inpatient length of stay.To maximize the efficacy and minimize the side effects of different options,a multi-modal analgesic regimen was recommended for patients underwent knee surgeries.Local wound infiltration and nerve block are given considerable attentions.Compared with systematic analgesia,nerve block with local anesthetics has been revealed to provide superior analgesia and better recovery of joint function compared with systemic analgesics. Currently,systematic evidence is sparse related to the comparative efficacy of pain control between local wound infiltration and nerve block,the investigators therefore conduct this randomized controlled ...
The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee. The femoral nerve is the largest branch of the lumbar plexus, and arises from the dorsal divisions of the ventral rami of the second, third, and fourth lumbar nerves (L2-L4). It descends through the fibers of the psoas major muscle, emerging from the muscle at the lower part of its lateral border, and passes down between it and the iliacus muscle, behind the iliac fascia; it then runs beneath the inguinal ligament, into the thigh, and splits into an anterior and a posterior division. Under the inguinal ligament, it is separated from the femoral artery by a portion of the psoas major. The muscles innervated by the femoral nerve extend the knee. The nerve is also responsible for sensation over the front and inner sides of the thigh, shin, and arch of the foot.[citation needed] Within the abdomen the femoral nerve gives off small branches to the iliacus muscle, and a ...
Methods: Fifty patients undergoing total knee arthroplasty were randomly assigned to receive ultrasound-guided CFNB either with the catheter parallel to the nerve technique (parallel group, n = 25) or with the catheter perpendicular to the nerve technique (perpendicular group, n = 25). Patient-controlled morphine analgesia pumps were available to all the patients after surgery. The time of catheter insertion, failure rates, pain scores, morphine consumption, nausea and vomiting, and maximal degree of knee flexion were recorded. ...
Continued From Above... From the lumbar plexus it extends with the fibers of the psoas major muscle inferiorly through the abdomen along the anterior surface of the hip bone. As it passes through the abdomen, a branch of the femoral nerve extends to provide nervous connections to the iliacus muscle, a flexor of the thigh. From the abdomen the femoral nerve next passes deep to the inguinal ligament in the groin and crosses the hip joint to enter the femoral region. In the femoral region, the femoral nerve separates into two nerve trunks - the anterior and posterior divisions - before further dividing into many smaller branches throughout the anterior and medial thigh.. Several cutaneous and muscular branches split from the anterior branch of the femoral nerve to carry nerve signals to specific targets in the thigh and leg. The medial cutaneous branch spreads vertically throughout the skin of both the medial thigh (through its anterior branch) and the medial leg (through its posterior branch). ...

After arrival in the operating room, each patient was positioned supine and IV catheters (for pharmacokinetic sampling, drug and fluid administration) were placed at the upper limbs. If deemed necessary by the anesthesiologist, a light sedation using IV fentanyl (0.75 μg/kg) was given. Femoral nerve block was performed by the anterior approach using both ultrasonic guidance and neurostimulation. A linear array ultrasound transducer (L10-5, Zonare Medical System, USA) was used to identify the neurovascular structures. Ultrasound use allowed the anesthesiologist to visualize the site of injection, that is, under the fascia iliaca in a circumferential manner with regard to the nerve. After skin infiltration with 1% lidocaine, a short bevel 50-mm, 22-gauge, Teflon-coated neurostimulation needle (Stimuplex, B Braun, USA) was advanced toward the femoral nerve in order to elicit an ipsilateral quadriceps contraction with upward patellar movement at less than 0.5 mA (extraneural). At this point, after ...

Although the analgesic effects of periarticular multimodal drug injection (PMDI) after TKA have been well documented, there is little information about additional pain relieving effects of PMDI incorporated to contemporary multimodal pain control protocols which have been proved to provide excellent analgesia. We performed a parallel-group, randomised, controlled study to determine whether PMDI provides additional clinical benefits on contemporary multimodal analgesic protocols including preemptive analgesics, continuous femoral nerve block, and IV-PCA. Eighty-seven patients were randomized to a PMDI group ( n = 45) or to a No-PMDI group ( n = 42). Pain level and opioid consumption were compared as primary outcomes. The incidences of narcotic and ropivacaine related side effects and complications, functional recovery, and satisfaction were also compared. The PMDI group experienced less pain during the operation night and the 1st postoperative day and showed lower opioid consumption over 24 h ...
The continuous popliteal approach to the sciatic nerve is used for the postoperative pain control following major foot and ankle surgery. It is almost always necessary to combine this block with a continuous femoral nerve block. ...
Introduction. Balancing pain control, while allowing patients to ambulate in the immediate postoperative period has been important to both anesthesiologists and orthopedic surgeons alike. Proper pain control reduces surgical stress and lessens cardiovascular related adverse events (1). Maintaining quadriceps strength allows patients to meet ambulation goals, reduces the threat of venous emboli, and increases likelihood of having a successful surgical outcome (2,3). Many methods have been developed to provide analgesia, such as femoral nerve continuous catheter placement however motor blockade can leave significant quadriceps weakness (4).. Recently, the adductor canal block (ACB) has gained popularity because it maintains quadriceps strength (5) while providing equivalent analgesia to the knee as the more traditional femoral nerve blockade (FNB). This is important because the functional impairment seen with FNB has been shown to increase the risk for falls perioperatively (6). ACB can be ...

Most people are aware of the sciatic nerve, but the femoral nerve is important too! While the sciatic nerve courses along the back side of our bodies (through the buttocks area, down the back of the leg and then splitting near the knee and continuting to the toes), the femoral nerve runs along the front side of our bodies. If the femoral nerve is pinched in the low back, the person will typically have symptoms of pain, numbness, or tingling in the groin area and/or the front of the thigh. -- ...
The nerve entrapment syndromes of the lower extremity include the following conditions:. The iliohypogastric (T12, L1), ilioinguinal (T12, L1) and genitofemoral (L1, 2) entrapment syndromes usually occur after lower abdominal surgery.92. Entrapment of the lateral femoral cutaneous nerve (L2-4) is also known as meralgia paraesthetica. Symptoms include anterior and lateral thigh burning, tingling and numbness.92. The femoral nerve (L2-4) is usually entrapped below the inguinal ligament where it lies in close proximity to the femoral head, the tendon insertion of the vastus inter-medius, the psoas tendon, and the hip joint and hip joint capsule, all of which can cause entrapment.92 Other causes of entrapment include methylmethacrylate heat during total hip arthroplasty, pelvic procedures requiring acutely flexed, abducted and externally rotated positioning, compression by a foetus in difficult childbirth, pelvic fractures and radiation.92. The saphenous nerve (L3,4) is the terminal and longest ...
The sciatic nerve is the longest, widest nerve in the body. It is derived from the 4th lumbar nerve and 3rd sacral nerve. It gives off muscular and articular branches.. The articular branches supply the hip joint and the skin of the leg.. The muscular branch splits into the tibial nerve and common fibular nerve which innervate all the muscles of the lower leg and some muscles of the foot (see below). Femoral Nerve. The femoral nerve originates from lumbar nerves 2, 3 and 4 and is the largest nerve branching from the lumbar plexus. Shortly after crossing the femoral triangle, the nerve splits into several branches; some deep, some superficial.. The superficial branches are sometimes known as the anterior division. This includes both cutaneous branches and muscular branches.. The cutaneous branches are the intermediate and medial cutaneous nerves. The intermediate cutaneous nerve innervates the skin of the leg down to the knee. It splits into several smaller branches which communicate with a ...
Ultrasound Guided Sub-Sartorial Saphenous Nerve Block. Overview of the Block. The saphenous nerve is a sensory only branch of the femoral nerve which covers the medial portion of the lower leg to the medial malleolus. It is most commonly used in combination with a popliteal sciatic or lower anterior sciatic block for procedures and injuries of the mid-lower leg and ankle. The saphenous nerve branches from the femoral nerve fairly high in the thigh and then travels with the superficial femoral artery in the "adductor tunnel" between the medial border of the vastus medialis muscle and the medial border of the adductor muscles. This pathway runs from lateral to medial beneath the course of the sartorius muscle. At the point in the distal thigh where the superficial femoral artery changes course to a deeper plane to become the popliteal artery, the saphenous nerve follows the small descending genicular artery to emerge from between the "adductor tunnel" to eventually diverge from the artery and ...
Results of a study of 80 total knee replacement patients that appears in the June edition of Anesthesia & Analgesia provides evidence that a nerve block technique which avoids the femoral nerve results in the need for less morphine and a potentially speedier recovery from the procedure.. Researchers determined that infusing pain-control medication through a catheter in the adductor canal of the mid-thigh - rather than higher up near the femoral nerve - provides better pain control and prevents temporary weakness of the leg muscles. This allows recovering patients to walk sooner and with more strength, resulting in improved participation in physical therapy. Patients in the study also needed less morphine to control post-surgical pain. Read a news story about the findings, with link to the article abstract, here.. Posted on May 30, 2014. ...
For histological analyses, we have chosen the two major branches of the femoral nerve, the quadriceps muscle nerve, and the cutaneous saphenous nerve of the mouse. In some experiments, sciatic nerves have been investigated at the level of the sciatic notch. In addition, we investigated the spinal roots of the third and fourth lumbar segment.. For detection and quantification of T lymphocytes, antibodies to CD8 (a gift from R. Zinkernagel, University of Zürich, Zürich, Switzerland) have been used on serial nerve cryosections as described previously (Schmid et al. 2000).. For detection of macrophages, antibodies to mouse F4/80 (1:300; Serotec) were applied overnight on 14-μm-thick serial sections from fresh frozen femoral nerves and spinal roots. To visualize primary antibodies, a biotinylated secondary antibody to rat Igs was applied for 1 h, followed by avidin/biotin reagent (Dako) and staining with diaminobenzidine-HCl and H2O2. For negative control, the primary antibody was omitted. In ...
The main problem is I cant have a femoral nerve block for pain relief post-op. As I suspected, my hip/groin area is too mangled and abnormal from previous surgeries, with a lot of scar tissue, and very little muscle - the anaesthetist couldnt even find my femoral vein, let alone the nerve. And an epidural isnt recommended; apart from the risk of permanent paralysis, it reacts badly with the DVT (Deep Vein Thrombosis) anti-clotting med Clexane which Ill be on for a month. So that means nothing that will numb just my leg for the first 2 days. My surgeon can flood the hip with local anaesthetic which will give me about 12 hours coverage after surgery, and Ill have to rely on PCA (Patient Controlled Analgesia) for the rest ...
