Intravenous (I.V.) Regional Anesthesia

Intravenous (I.V.) regional anesthesia is also sometimes called a Bier block. It uses numbing medicines to block pain in the arm or hand during a procedure.

How it's done

A small tube (I.V.) is inserted into a vein in the hand of the arm that is being numbed. Then the arm is wrapped tightly from the hand up to above the area where the procedure will be done. This moves blood out of the arm and back into the body.

A tight band is put around the arm at the top of the wrap. When the band is secure, the wrap is removed. Numbing medicine is put into the I.V. in the hand. It numbs the area of the arm below the band for the procedure.

How to prepare

You will get a list of instructions to help you prepare. Your anesthesia specialist will let you know what to expect when you get to the hospital, during the surgery, and after.

You'll be told when to stop eating and drinking.

If you take medicine, you'll be told what you can and can't take before surgery.

You'll be asked to sign a consent form. The form says that you know the risks of anesthesia. Before you sign, your specialist will talk with you. You'll discuss the best type for you. And you'll learn the risks and benefits of that type.

Many people are nervous before they have surgery. Ask your doctor about ways to relax before surgery.

What to tell the doctor

Tell the provider about any health problems (such as sleep apnea). Talk about any past surgeries and if a family member had problems with anesthesia. Let them know if you're pregnant. Also tell them if you smoke, vape, or use other tobacco or nicotine products, drink alcohol, or use drugs. Give them a list of all medicines, vitamins, and herbal products you take.

Risks

Problems from I.V. regional anesthesia aren't common. There may be soreness or bruising at the I.V. site or where the band was placed. There may be numbness and tingling. If the medicine moves past the band into the body, there may be side effects such as ringing in the ears and dizziness.
