An autonomic nerve block refers to a medical procedure that involves the administration of a local anesthetic to block the transmission of signals within the autonomic nervous system. The autonomic nervous system is responsible for regulating many involuntary bodily functions such as heart rate, blood pressure, digestion, and sweating.
During an autonomic nerve block, a healthcare professional injects a local anesthetic, such as lidocaine or bupivacaine, into specific nerves that control the autonomic functions related to the targeted area. This can be performed in various parts of the body, such as the head, neck, chest, abdomen, or pelvis.
The purpose of an autonomic nerve block is to interrupt the transmission of pain signals and alleviate symptoms associated with certain conditions or diseases that involve abnormal autonomic function. This may include disorders like complex regional pain syndrome (CRPS), facial pain syndromes, vasomotor disorders, or even certain types of headaches.
The local anesthetic works by numbing the nerves and blocking the release and reception of neurotransmitters responsible for transmitting pain signals. By interrupting these signals, the autonomic nerve block aims to reduce pain, decrease inflammation, restore normal autonomic function, and improve overall quality of life for the patient.
Autonomic nerve blocks can be performed using various techniques, such as nerve stimulators, ultrasound guidance, or fluoroscopy. It is crucial for these procedures to be performed by trained professionals in a sterile and controlled environment to minimize the risks and ensure optimum outcomes.
