“…When using the LOR (loss of resistance) technique the rate of blockage is around 80% while using a nerve stimulator gives success rates of over 95%, we have reached 100% in this series [5]. Saphenous nerve block in arthroscopic medial menisectomy has given superior results in resting and activity VAS values during the first day after surgery when compared to the control group and also it facilitated a reduction in the need for post operative analgesia using tramadol for pain relief.…”

In this study we have evaluated the post menisectomy pain relief offered by Saphenous nerve block. This study was planned on 40 patients with a pre-operative and post operative diagnosis of medial meniscus lesion undergoing partial menisectomy arthroscopically. Patients were randomized into 2 groups where Group I received a preoperative Saphenous block while group 2 did not receive a peripheral block, but received 1 ml of saline as placebo injection. After blocks both groups received general anesthesia and IV patient controlled analgesia (PCA) with tramadol for post operative pain relief. Patients rest and activity pain scores were evaluated on post operative 0, 2, 4, 6, 12 and 24 h using visual analog scale (VAS). Total tramadol consumption as well as pain at rest, when weight bearing and the need for external support while walking were recorded. Group I VAS scores were statistically lower then group II during the time of observation periods at rest as well as active movement periods. Tramadol consumption through IV PCA was statistically significantly lower in group I than in group II (P < 0.05). Pain during walking measured at 24 h was significantly different with better results in group I (P < 0.001). Saphenous nerve block is used for different indications; it can also be a good analgesic method for arthroscopic interventions. We have shown it to be effective after medial partial menisectomies. According to our knowledge this report is the first one utilizing saphenous nerve block for pain after arthroscopic medial menisectomy.

“…In an effort to refine the transsartorial technique, LOR, and (sensory) PNS were compared in a group of 25 volunteers 127. Despite an improved success rate (100% vs 72%; p<0.05), the PNS technique was associated with more procedural pain score and a longer performance time.…”

The advent of ultrasound guidance has led to a renewed interest in regional anesthesia of the lower limb. In keeping with the American Society of Regional Anesthesia and Pain Medicine’s ongoing commitment to provide intensive evidence-based education, this article presents a complete update of the 2005 comprehensive review on lower extremity peripheral nerve blocks. The current review article strives to (1) summarize the pertinent anatomy of the lumbar and sacral plexuses, (2) discuss the optimal approaches and techniques for lower limb regional anesthesia, (3) present evidence to guide the selection of pharmacological agents and adjuvants, (4) describe potential complications associated with lower extremity nerve blocks, and (5) identify informational gaps pertaining to outcomes, which warrant further investigation.

O Ob bj je ec ct ti if f : : Évaluer la neurostimulation des fibres motrices destinées au muscle vaste médial et au muscle droit antérieur dans le but de bloquer les fibres sensitives médiales du nerf saphène.M Mé ét th ho od de e : : Dans un premier temps nous avons procédé à la dissection de quatre trigones fémoraux afin de choisir notre point de ponction: nous avons observé qu'au niveau du pli de flexion de la cuisse, les différentes fibres constituant le nerf fémoral étaient très ramassées les unes par rapport aux autres et que le nerf saphène avec le nerf du muscle vaste médial ne s'étaient pas encore individualisés du tronc fémoral. Dans un deuxième temps, nous avons réalisé une étude clinique prospective chez 71 patients, opérés du tiers inférieur de la jambe sous bloc sciatique et bloc du nerf saphène. Le bloc du nerf saphène a été réalisé avec 10 mL d'anesthésique local en ponctionnant au niveau du pli de flexion de la cuisse, en recherchant une des deux réponses musculaires : médiale (contraction du muscle vaste médial) ou antérieure (contraction du muscle droit antérieur avec ascension de rotule).R Ré és su ul lt ta at ts s : : Le taux de succès global sur le nerf saphène est de 80 %, sans différence statistique entre les deux types de réponses. La durée moyenne de réalisation du bloc est de deux minutes et le délai moyen d'obtention de l'anesthésie est de 15 min. Aucune complication n'a été relevée hormis une ponction de l'artère fémorale sans conséquence clinique.C Co on nc cl lu us si io on n : : La neurostimulation du muscle vaste médial est équivalente à la neurostimulation du muscle droit antérieur pour l'anesthésie du nerf saphène. A efficacité comparable, la neurostimulation du compartiment médial du nerf fémoral permet une économie d'anesthésique local par rapport à un bloc fémoral classique. Purpose: To evaluate neurostimulation of motor components of the vastus medialis muscle and the rectus femoris muscle, with a view to blocking the medial sensory fibres of the saphenous nerve. Method: First we dissected four femoral trigones, in order to select our puncture point. We were able to observe that, at the flexion crease of the thigh, the different fibers that make up the femoral nerve were clustered together and the saphenous nerve and the vastus medialis nerve had not yet separated from the femoral stem. Secondly, we conducted a prospective clinical study among 71 patients who had undergone surgery on the lower third of the leg with a sciatic block and a saphenous nerve block. The saphenous nerve block was performed using 10 mL of local anesthetic, by puncturing the flexion crease of the thigh in a bid to obtain one of two muscle responses: medial (contraction of the vastus medialis muscle) or anterior (contraction of the rectus femoris muscle and elevation of the patella).
