“…The area innervated by the obturator nerve are affected during a very short period of the procedure and can be managed with sedoanalgesia. The LFC nerve transmits the pain caused by the concomitant tourniquet rather than the surgical nociception [22]. Transmission by the LFC nerve increases mostly when the tourniquet pain increases, usually near the end of the operation.…”

BackgroundAlthough regional anesthesia is the first choice for patients undergoing total knee arthroplasty (TKA), it may not be effective and the risk of complications is greater in patients who are obese or who have spinal deformities. We compared the success of ultrasound-guided femoral and sciatic nerve blocks with sedoanalgesia versus spinal anesthesia in unilateral TKA patients in whom spinal anesthesia was difficult.MethodsWe enrolled 30 patients; 15 for whom spinal anesthesia was expected to be difficult were classified as the block group, and 15 received spinal anesthesia. Regional anesthesia was achieved with bupivacaine 62.5 mg and prilocaine 250 mg to the sciatic nerve, and bupivacaine 37.5 mg and prilocaine 150 mg to the femoral nerve. Bupivacaine 20 mg was administered to induce spinal anesthesia. Hemodynamic parameters, pain and sedation scores, and surgical and patient satisfaction were compared.ResultsA sufficient block could not be obtained in three patients in the block group. The arterial pressure was significantly lower in the spinal group (P < 0.001), and the incidence of nausea was higher (P = 0.017) in this group. Saturation and patient satisfaction were lower in the block group (P < 0.028), while the numerical pain score (P < 0.046) and the Ramsay sedation score were higher (P = 0.007).ConclusionsUltrasound-guided sciatic and femoral nerve blocks combined with sedoanalgesia were an alternative anesthesia method in selected TKA patients.

“…The anterolateral part is supplied by the fully sensory lateral femoral cutaneous nerve (LFCN) (L2-L3) ( 7 ), which is said to conducts the pain of tourniquet rather than the surgical noxious stimulus ( 8 ). However, a single blockade of LFCN has been shown to have little effect on reducing thigh tourniquet pain ( 9 ). Alternatively, the combination of LFCN and femoral blocks may provide better relief of the tourniquet pain ( 10 ).…”

Comparison of the Combined Femoral and Lateral Femoral Cutaneous Nerve Block Plus Popliteal Block with Spinal Anesthesia for Thigh Tourniquet Pain During Foot or Ankle Surgery: A Randomized Clinical Trial

Background: A pneumatic thigh tourniquet is routinely used during lower-extremity orthopedic surgeries to provide a bloodless field. When using peripheral nerve blocks, tourniquet-related thigh pain and discomfort limit their routine use as an anesthetic method. Objectives: The aim of the present prospective, randomized study was to compare the efficacy of combined femoral nerve/lateral femoral cutaneous nerve block technique and spinal anesthesia on intraoperative thigh tourniquet pain. Methods: We studied 60 American Society of Anesthesiologists physical status I-II patients scheduled for orthopedic surgery on the foot or ankle using a pneumatic thigh tourniquet. They were randomly divided into two equal groups. The peripheral nerve block group received a combined popliteal, femoral, and lateral femoral cutaneous nerve block under ultrasound-guidance. In both groups, the level of sensory blockade was determined by the pinprick test. The block performance time, anesthetic effect time, intraoperative tourniquet pain scores, the amount of fentanyl and ketamine, surgery duration, and patient’s satisfaction were recorded. Results: The patients’ characteristics were comparable in the two groups. The mean duration of block performance and anesthetic effect, intraoperative tourniquet pain scores, and the amount of intravenous analgesics in the peripheral nerve block group were significantly greater than those in the spinal anesthesia group. Patient satisfaction was similar in both groups. Conclusions: Spinal anesthesia is significantly more effective than the peripheral nerve block method in reducing thigh tourniquet pain. A combined femoral and lateral femoral cutaneous nerve block with popliteal block can improve thigh tourniquet tolerance if supplemented with intravenous analgesics.

Ist die Blockade des N. cutaneus femoris lateralis eine Alternative zu einer klassischen Femoralisblockade bei Kniegelenkarthroskopien?

Abstract: An LFCN block is not a suitable alternative to an FN block for regional anaesthesia. For patients with contraindications for an FN block according to Winnie (e.g. vessel surgery in the groin) other more effective methods are available.
