Description

Regional anesthesia is a type of pain management in surgery that paralyzes most of the body such as from the waist down, or from the arms, legs, and abdomen. The drug is given through a small tube called an injection or catheter and is used when a simple injection of a Regional anesthetic is not enough and when it’s better for the patient to be awake. This type of anesthesia, including spinal anesthesia and epidural anesthesia, is commonly used for childbirth. In fact, epidural anesthesia is the most common type of pain management used during delivery. It allows the mother to wake up and push when it is time to give birth to the baby, but it paralyzes the pain. Another type of regional anesthesia is spinal block and it is stronger and is used during procedures such as cesarean deliveries, also known as Csections. Spinal blocks and epidurals allow the doctor to surgically deliver the baby without causing pain to the mother, and without subjecting the baby to sedating drugs that might be harmful. Regional anesthesia is very safe and doesn`t involve the potential complications and side effects that can happen with sedation and general anesthesia. But it does carry some risks, and it`s important that it be provided and monitored by a physician anesthesiologist.

Major types of regional anesthesia

Peripheral nerve blocks: Regional anesthetics are injected near specific nerves or nerve bundles and block the sensation of pain from areas of the body supplied by the nerves. Nerve blocks are most commonly used for arm and hand, leg and foot, groin, or facial surgery.

Epidural and spinal anesthesia: A Regional anesthetic is injected near the spinal cord and the major nerves that enter the spinal cord, blocking the sensation of pain from all areas of the body, including the lower abdomen, lower back, and legs.

In Regional anesthesia, the anesthetic is injected near the nerve, nerve bundle, or spinal cord. Anesthesiologists need the skills and experience to inject anesthetics in the right places, as the site of the anesthetic injection can have a significant impact on its effectiveness. Careful technique is required to reduce the risk of rare complications such as infections and nerve damage. The injection site also has a significant effect on the rate at which the anesthetic is absorbed by the rest of the body. People under local anesthesia are carefully monitored because the anesthetics used can affect the "airways and lungs" of the central nervous system, cardiovascular system, and respiratory system. This is especially important in spinal anesthesia because it can affect blood pressure, breathing, heart rate, and other important functions. Regional anesthesia also carries the risk of systemic toxicity if the anesthetic is absorbed through the bloodstream into the body. Other complications include heart or lung problems, and infection, swelling, or bruising (hematoma) at the injection site. Regional anesthesia is different from general anesthesia, which works on the entire body, not just the surgery site, and the patient sleeps through surgery. It differs from local anesthesia in that a larger region of the body is numbed.

Epidurals and other types of regional anesthesia are typically provided by an anesthesiologist or a nurse anesthetist (CRNA). If desired, anesthesia can be performed with a needle, or the needle can be used to insert a flexible catheter and administer anesthetics and other medications as needed. It can be used to insert a flexible catheter that can administer anesthetics and other medications throughout the procedure. Regional anesthesia is provided by injecting a paralyzing drug into a specific site that acts on the nerves of the body, causing numbness under the injection site. If you have hand surgery, anesthesia may cause numbness in your arms or entire hand, or the numbness may be mostly limited to your hands. Epidural anesthesia, or spinal block, is given to the back. Epidurals will provide continuous pain relief as long as medications are continuously running and the patient is not having any other side effects. Spinal blocks are given with a needle to the spinal sac, with the medication entering the cerebrospinal fluid. It uses a finer needle than an epidural. A peripheral nerve block may be given in the shoulder arm, back, or leg regions. By choosing the site, different levels of the limb may be numbed. The anesthetic does not penetrate the nerve, but is injected near the nerve. You can use a nerve stimulator or a portable ultrasound device to locate the target nerve. Specific nerve blocks include arm plexus block, paravertebral block, femoral nerve block, sciatic nerve block, and patellar nerve block.
