IV Regional Block
Also known as a Bier Block, an IV regional block is used for surgical procedures of the lower arm or hand. The block involves placement of a tourniquet, similar to a blood pressure cuff, on the upper arm to be blocked, and injection of local anesthetic into an IV placed in the hand or forearm. This type of block is appropriate for surgical procedures lasting less than one hour. In addition to the local anesthetic, you may also receive some form of sedation to keep you comfortable. Possible side effects include infection, convulsions, persistent weakness, numbness or pain, injury to blood vessels, loss of limb, or unconsciousness necessitating general anesthesia.
