Lateral approach to the sciatic nerve in the popliteal fossa.

UNLABELLED: We describe a modification of the sciatic nerve (SN) block in the popliteal fossa through the lateral approach. After a brief anatomic study using previously reported landmarks, we propose a new needle orientation associated with a double injection technique after identification of the tibial and the common peroneal nerve. Thirty-four patients undergoing ankle or foot surgery were enrolled in this study. With patients in the supine position, the upper edge of the patella and the groove between the posterior border of the vastus lateralis and the anterior border of the tendon of the biceps femoris were identified. The needle was directed posteriorly with a 20-30 degrees angle relative to the horizontal plane and slightly caudal. Both nerves were individually located with a nerve stimulator and blocked with a mixture of lidocaine-bupivacaine and clonidine. In all but one case, the two nerves were easily located, and no vascular puncture was evident. Effective analgesia was obtained for a minimum of 15 h (first analgesic demand). We conclude that this technique, with a modified direction of the needle and a double stimulation, provides a very high rate of success for SN blockade in the popliteal fossa. IMPLICATIONS: We describe a new lateral approach to the sciatic nerve in the popliteal fossa. The needle was directed caudad and posteriorly while seeking with a nerve stimulator for the tibial and the peroneal nerves, which were blocked separately. This technique was very successful.

[Sciatic nerves block].

Sciatic nerve block is considered difficult to perform, but very useful for lower limb anaesthesia and analgesia. The use of a nerve stimulator makes the technique easier. Functionally, it is better to consider that there are three independent sciatic nerves, namely, the posterior cutaneous nerve, the tibial nerve and the common peroneal nerve. Searching for blocking these three nerves and especially the latter two, specifically improve the reliability and quality of blockade.

[Block of the lumbar plexus].

Lumbar plexus block is indicated in anesthesia and analgesia of the proximal part of the lower limb. Several techniques, two via the anterior approach and at least three via a posterior paravertebral approach have been described. All these techniques are not equivalent in terms of technical facilities or difficulties, efficacy, success or failure rates and postoperative analgesia. The best choice must be done keeping in mind all advantages or disadvantages of each technic.

[The truncal blocks of the foot].

Among the five branches of principal nerves trunks supplying the ankle and foot, only the tibial nerve is sometimes difficult to block at the ankle, at the border of the medial malleolus. Using new landmarks at the level of the sustentaculum tali overcomes this problem. Blocking these five nerves make possible all surgical procedures on the foot and provide excellent postoperative analgesia. Only tourniquet is a limit for these blocks.

[Truncal and peripheral blocks of the arm].

Blocking the median, the radial, the ulnar and the musculo-cutaneous nerves, alone or all together provide sufficient anaesthesia for hand and forearm surgery. Because of frequent anatomical variations and the possibility of a double nerve supply in some territories, blockade must be extended to the adjacent nerves. Tourniquet over the elbow is the only limit for these blocks, but they are useful to provide per and postoperative analgesia during general anaesthesia, and in some cases to improve the efficiency of brachial plexus block.
