Närviblokk

Närviblokk, often translated as nerve block, is a medical procedure used to temporarily or permanently interrupt nerve signaling. This interruption can be employed for various purposes, primarily pain management and anesthesia. By targeting specific nerves or nerve bundles, a närviblokk can numb a particular area of the body, alleviating pain from injuries, chronic conditions, or surgical procedures.

The procedure typically involves injecting local anesthetics, or sometimes other substances like corticosteroids or neurolytic agents, near the target nerve. The exact location and technique depend on the nerve being targeted and the intended outcome. Ultrasound or fluoroscopy guidance is often used to ensure accurate needle placement and maximize the effectiveness and safety of the block.

Närviblokk can be used for both diagnostic and therapeutic purposes. Diagnostically, it can help pinpoint the source of pain by observing whether blocking a specific nerve provides relief. Therapeutically, it offers a way to manage acute pain during surgery or for conditions like sciatica, carpal tunnel syndrome, or phantom limb pain. In some cases, repeated injections or more permanent nerve destruction techniques may be used for long-term pain relief. While generally safe, potential risks include infection, bleeding, nerve damage, or allergic reactions to the injected substances.
