Paravertebral Blockade of Nerves with Anesthetic Substances
We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.
Paravertebral blockade is a technique used in regional anesthesia to block the spinal nerves as they emerge from the intervertebral foramina. It involves injecting local anesthetic substances near the vertebral column to temporarily numb a specific area of the body. This procedure is commonly used for various surgical procedures, pain management, and diagnostic purposes.
Mechanism and Applications
The paravertebral space is a wedge-shaped area adjacent to the vertebral column, where the spinal nerves exit before branching into the intercostal nerves and other branches. By injecting local anesthetic agents into this space, the nerves are blocked, resulting in anesthesia or analgesia in the corresponding dermatomes and myotomes.
| Component | Description |
|---|---|
| Local Anesthetic | Substances like lidocaine, bupivacaine, or ropivacaine are injected to block nerve conduction. |
| Injection Site | The anesthetic is injected into the paravertebral space, typically at the level of the desired nerve block. |
| Nerve Blockade | The anesthetic spreads and blocks the spinal nerves as they emerge from the intervertebral foramina. |
Paravertebral blockade has various applications, including anesthesia for thoracic, abdominal, and pelvic surgeries, as well as pain management for conditions like chronic pain, rib fractures, and post-operative pain control. It can also be used as a diagnostic tool to identify the source of pain or for therapeutic purposes in certain neurological conditions.
Role of Paravertebral Blockade of Nerves with Anesthetic Substances
Paravertebral blockade of nerves with anesthetic substances is a medical procedure used to provide anesthesia and pain relief in various surgical and diagnostic procedures. This technique involves injecting local anesthetic agents near the spinal nerves, blocking the transmission of pain signals from the affected area to the brain.
Indications for Paravertebral Blockade of Nerves with Anesthetic Substances
The paravertebral blockade of nerves with anesthetic substances may be indicated in the following situations:
- Pain management for surgical procedures involving the chest, abdomen, or lower limbs.
- Relieving chronic pain conditions, such as cancer-related pain or post-surgical pain.
- Diagnostic purposes, such as identifying the location of pain or nerve involvement.
- Anesthesia for certain diagnostic procedures, like breast biopsy or thoracic surgeries.
- Chronic pain management in cases where other treatment options are ineffective or contraindicated.
Preparation for the Procedure
Prior to undergoing a paravertebral blockade of nerves with anesthetic substances, there are a few preparatory steps to consider:
- Disclosure of medical history: It's essential to inform your healthcare provider about any pre-existing medical conditions, allergies, or medications you're currently taking. This information helps ensure the procedure is safe and appropriate for your individual circumstances.
- Fasting: Depending on the specific anesthetic agent and the procedure, you may be required to fast for a certain period before the procedure. Your healthcare provider will provide you with detailed instructions regarding fasting requirements.
- Clothing: You may be asked to wear loose, comfortable clothing or a hospital gown during the procedure to facilitate access to the treatment area.
- Medication adjustments: Your healthcare provider may advise you to temporarily discontinue certain medications or adjust their dosages to minimize potential interactions or complications during the procedure.
The Procedure
The paravertebral blockade of nerves with anesthetic substances is typically performed by an anesthesiologist or a trained healthcare professional. The procedure involves injecting a local anesthetic near the nerve roots along the vertebral column to numb the target area. The specific technique and anatomical location will depend on the purpose of the procedure and the area being treated.
Performing the Paravertebral Blockade of Nerves with Anesthetic Substances
Paravertebral blockade of nerves with anesthetic substances is a procedure performed to block the transmission of pain signals along specific nerve pathways. It involves injecting an anesthetic agent, such as a local anesthetic or a steroid, into the paravertebral space, which is the area adjacent to the vertebral column. This procedure can be used to manage various types of pain, including chronic pain conditions, post-operative pain, and pain associated with certain medical conditions.

IMPORTANT!
It is crucial to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience pain or an exacerbation of a condition, it is essential to seek medical attention for proper diagnostic evaluations. Only a qualified healthcare professional can make an accurate diagnosis and determine the appropriate treatment plan. To ensure the most accurate and consistent assessment of test results, it is recommended to have them conducted at the same laboratory. Different laboratories may use varying methods and units of measurement for similar tests.
