What Does Sciatic Nerve Block Puncture Needle Mean

Sciatic nerve block is a kind of local anesthesia. The method of nerve block is to inject local anesthetic drugs into the side of the sciatic nerve. The sciatic nerve block can be done by blind exploration or under the guidance of B-ultrasound. In this way, after the injection of local anesthetics next to the sciatic nerve, the conduction function of the sciatic nerve can be blocked, and there is no pain induction in the area innervated by the sciatic nerve, and the patient will not feel any pain stimulation during the operation.

The most commonly selected puncture points for sciatic nerve blocks are located between the piriformis and the superior gemellus muscle, including the lateral and supine sciatic nerve blocks, which are mainly used for the treatment of sciatica and piriformis syndrome and can significantly relieve sciatic nerve pain. The purpose of treatment can be achieved by sciatic nerve block, analgesic effect of anesthetic drugs and anti-inflammatory effect. This condition can play a role in clinical treatment, but also can play a role in differential diagnosis.
