Nerve Block Methods Of Various Puncture Needles

Nerve block is the injection of a local anesthetic around the nerve stem to produce an anesthetic effect. Nerve blocks from head to foot include cervical plexus block, brachial plexus block, lumbar plexus block, sciatic nerve block, etc. In these nerve blocks, drugs are injected around the nerve stem and plexus to numb parts of the body that are innervated by the nerve stem and plexus.

When doctors operate hand surgery, they can block the nerve of the arm, so that the pain of the whole hand is lost, then they can continue to operate. Especially for some elderly patients, they can receive general anesthesia for hand surgery, but the heart and lung function is very poor, general anesthesia is easy to inhibit circulation and breathing. For this kind of situation, nerve block can be given, which is more beneficial for elderly patients with more complications. This procedure should be performed with care, and it should be noted that nerve block is a specific toxic effect of local anesthesia, but it can be performed safely by experienced anesthesiologists.
