What are the side effects of regional anesthesia?
These can be:
- Nausea and vomiting (most common once)
- Headache
- Dry mouth (because of being nil by mouth for the procedure and fluid loss during procedure)

How do you get regional anesthesia?
Regional anesthesia may be given with other medicines that make you relaxed or sleepy (sedatives) or relieve pain (analgesics). These other medicines are given through a vein (intravenously, IV). Regional anesthesia is most often used when the procedure: Is confined to a specific region of the body.
What does regional anesthesia stand for?
Regional anesthesia refers to numbing a region of the body, rather than the whole body by inducing unconsciousness with general anesthesia.. Regional anesthesia includes peripheral nerve blocks and neuraxial anesthesia. A special type of block called an IV (intravenous) regional anesthetic may also be included in this category.
What is regional Anaesthesia?
Regional anesthesia is a type of pain management for surgery that numbs a large part of the body, such as from the waist down.
What is the difference between regional and local anesthesia?
Local anesthesia numbs just a small area of tissue where a minor procedure is to be done. Regional anesthesia numbs a larger (but still limited) part of the body and does not make the person unconscious.
Are you awake during regional anesthesia?
Even if you choose regional anesthesia instead of general anesthesia, you don't have to be “awake” during surgery. Anesthesiologists often combine regional anesthesia with either intravenous sedation or general anesthesia, both of which can allow you to fall asleep during surgery.
What are the types of regional anesthesia?
Types of regional anesthesia include spinal anesthesia (also called subarachnoid block), epidural anesthesia, and nerve blocks.
Is regional anesthesia better than general anesthesia?
Regional anesthesia is the preferred anesthetic technique for patients undergoing orthopedic surgery because it is associated with less postoperative pain and nausea, a lower incidence of blood clots, less blood loss, and a lower infection rate compared with general anesthesia.
Does regional anesthesia hurt?
The placement of a nerve block is associate with minor discomfort. Most patients report that it is less painful than the placement of a small IV catheter. We give all patients sedating medicine to help you relax and then numb the skin prior of the nerve block placement.
What does regional anesthesia feel like?
During a surgical procedure, regional anesthesia causes numbness and blocks pain in an entire area of the body, such as your lower body, abdomen, leg, or arm. It's usually given as single injection or continuously through a small catheter.
How long does regional anesthesia last?
How Long Will the Regional Anesthesia Last? If you receive a single injection of medicine to numb your nerves, you can expect 4-24 hours of pain relief after surgery. This may vary depending on the medication used. These injections are often used for pain control after bone surgery.
Where is regional anesthesia injected?
For regional anesthesia, an anesthetic is injected close to a nerve, a bundle of nerves, or the spinal cord. In rare cases, nerve damage can cause persistent numbness, weakness, or pain. Regional anesthesia also carries the risk of systemic toxicity if the anesthetic is absorbed through the bloodstream into the body.
Is regional anesthesia safer than general?
Regional anesthesia, which numbs a larger part of the body, such as from the waist down, is also safer than general anesthesia, but it does carry some risks. Patients sometimes experience headaches after having regional anesthesia.
What drug is used for regional anesthesia?
Among the adjuvants to local anesthetics, clonidine is by far the most used drug in regional anesthesia; its yield in improving and prolonging the effects of local anesthetics is apparent in neuraxial techniques.
What are the risks of regional anesthesia?
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.
What is interscalene block?
Interscalene blocks are useful for shoulder surgery. Like femoral nerve blocks, they are usually used in conjunction with general anesthesia, rather than by themselves. They are most useful to decrease the amount of general anesthesia needed and to provide pain relief for the first six to 18 hours after surgery.

What is Bier block?
Bier blocks (IV regional) involve the use of a tourniquet applied to an arm after the blood has been squeezed and drained from it. Local anesthetic is placed into a vein in the hand, and the arm is anesthetized until the tourniquet is released or the anesthetic is metabolized.
What is a tourniquet used for?
A tourniquet to occlude the now compressed blood vessels is inflated in the upper arm (a double tourniquet can be used, as well, to improve safety and patient comfort ).

What is a fetal nerve block?
Femoral nerve block being placed with the use of an ultrasound probe to guide the needle toward, but also to protect, the nerve. Other techniques also provide safe and effective blocks.
Why does gas insufflate the abdomen?
First, the abdomen is inflated with gas to create a dome in which the surgeon can work. This insufflation of gas causes pain above the area that can be safely covered by the regional anesthesia. Also, the gas makes it harder to breathe adequately, as can spinal or epidural anesthesia.
How long do Bier blocks last?
They are useful for surgery on the hand or lower arm that lasts less than about one hour.

What is the difference between regional and general anesthesia?
A key difference between regional anesthesia and general anesthesia – another type of anesthetic approach – is breathing. Under general anesthesia, patients need a device to help them breathe during surgery; under regional anesthesia, patients sleep as though they were in their own bed.
How is regional anesthesia different from general anesthesia?
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. An epidural being administered. Getty Images/BSIP/UIG.

Who provides regional anesthesia?
Epidurals and other types of regional anesthesia are typically provided by an anesthesiologist or a nurse anesthetist (CRNA). Depending on the need, the anesthesia may be given with a needle or a needle may be used to insert a flexible catheter line through which anesthetics and other medications can be administered as needed.
What is the brachial plexus?
The brachial plexus is the major nerve bundle going to the shoulder and arm. Depending on the level of surgery, your anesthesiologist will decide at what level he wants to block the brachial plexus. For example if you have surgery at the shoulder, your anesthesiologist may choose a nerve block (interscalene or cervical paravertebral block) performed at a location above the clavicle. For surgeries below the shoulder joint or clavicle, an infraclavicular or axillary technique may be used. Your anesthesiologist may use ultrasound, a nerve stimulator or other techniques to help identify the appropriate location along the brachial plexus to inject the local anesthetic. If a nerve stimulator is used, you may feel the muscles in your shoulder or arm twitch. This is normal. If you experience any sharp pain or any type of paresthesia ("shock-like" sensation similar to if you were to hit your "funny-bone" in your elbow) shortly before or during the injection you should notify your anesthesiologist immediately. You should also notify your anesthesiologist before performing any brachial plexus block if you have any type of pain below the elbow, preexisting pain, or preexisting nerve injury. If you have serious respiratory (lung, breathing) problems you should notify your anesthesiologist before proceeding with the block. Your anesthesiologist will then decide whether a brachial plexus block is safe for you and will provide adequate analgesia for the surgery.
What is the procedure to numb a nerve block?
The anesthesiologist will use local anesthesia to numb an area of where the peripheral nerve block will be administered.

Where is the CSF needle placed?
An extremely small needle is placed through the skin, soft tissue, and ligaments surrounding the spine until it reaches the subarachnoid space , which is where cerebrospinal fluid (CSF) is found. A small amount of local anesthetic specifically designed to go into the CSF is given, and the needle is taken out.
Where does numbness start?
Numbness usually starts at the feet and moves upward. The spread of numbness is determined by many things, including the amount and type of local anesthetic given, the patient's height, and the position of the patient once the medication is given. Epidural anesthesia.
Is epidural anesthesia the same as spinal anesthesia?
Epidural anesthesia is similar to but not the same as spinal anesthesia. For epidural anesthesia, a larger needle that does not reach the CSF is used, and a catheter is placed through that needle into the epidural space. Using the catheter, longer-term anesthesia and pain relief can be obtained.
What is a PDPH headache?
A spinal or postdural puncture (PDPH) (or also sometimes called a meningeal puncture headache) may occur after spinal or epidural anesthesia when puncture of the dural sac allows for spinal fluid to leak out of the dural sac. If enough spinal fluid leaks out, a headache may occur especially when standing or sitting.

What is the complication of cervical paravertebral interscalene?
An important, although very rare, complication of the cervical paravertebral, interscalene, or infraclavicular blocks, is the development of a pneumothorax (air trapped between the lung and the rib cage).
What happens if a nerve block does not disappear?
If they do not disappear or become severe, additional treatments are available . There are veins in the epidural space and other areas where epidural nerve blocks are administered. There is a risk that the anesthetic medication could be injected into one of them.
How to treat a leaking puncture?

What is the role of an anesthesiologist in anesthesia?
The anesthesiologist or another member of the anesthesiology team, like a nurse anesthetist, monitors the patient’s breathing and vital signs during the procedure to ensure that the right amount of anesthetic is being used.
What is local anesthesia?
The use of local anesthesia allows patients to tolerate procedures that would cause discomfort only in that one small part of the body, like getting stitches to close up a wound or undergoing a biopsy or the skin or breast. This is the kind of anesthesia most commonly used for procedures that are performed right in a physician’s office, ...
How often is local anesthesia used?
Instead of continuous administration of medication, local anesthesia is usually applied just once, either topically or by injection, in a dosage amount that is intended to last the length of the procedure before it wears off naturally.
What is the highest paying medical specialty?
Anesthesiology, one of the highest-paying medical specialties, is the branch of medicine that focuses on pain relief. Anesthesia is what makes surgical procedures and uncomfortable diagnostic tests tolerable for patients.
Can an anesthesiologist give IV sedation?
IV sedation doesn’t achieve the same level of loss of consciousness that general anesthesia does, but – depending on the amount used and the purpose of sedating the patient – it can make patients feel drowsy or completely put them to sleep, according to the American Society of Anesthesiologists.
