Idegblockád

Idegblockád, also known as nerve block or neurolytic block, is a medical procedure used to interrupt nerve signals, primarily for pain relief. It involves injecting a local anesthetic or neurolytic agent near specific nerves or nerve bundles to temporarily or permanently block the transmission of pain signals to the brain.

Nerve blocks are commonly employed in various medical settings, including surgery, pain management, and palliative care. They can be used for diagnostic purposes, to identify the source of pain, or therapeutically to alleviate chronic pain conditions such as neuropathic pain, cancer pain, or pain associated with musculoskeletal disorders.

The procedure typically involves imaging guidance, such as ultrasound or fluoroscopy, to ensure accurate needle placement. The choice of anesthetic or neurolytic agent depends on the desired duration and intensity of the block. Local anesthetics provide temporary relief, while neurolytic agents like alcohol or phenol are used for longer-lasting or permanent nerve destruction.

Potential benefits of nerve blocks include effective pain reduction, decreased reliance on systemic pain medications, and improved functional capacity. However, like any medical procedure, nerve blocks carry risks, including infection, bleeding, nerve damage, and allergic reactions. The specific risks and benefits are discussed with the patient before the procedure.
