What is the bier block?
Bier block is a procedure to treat pain to prevent pain or legs. This anesthetic technique was promoted by Auguste Bier, a German physician who worked at the foreground of the backbone anesthesia and other anesthetic techniques in the early 20th century. Bier block includes nerve blocking that feeds the affected limb, and is often used in surgery performed on the arms, legs, hands or legs, in cases where the patient is inappropriate for general anesthesia. In addition, this technique can be used to treat chronic pain caused by pain disorders, such as chronic regional pain syndrome. In these situations, the Bier block is a much safer alternative when anesthesia is needed for arm or leg surgery. A patient who has this technique performed as an alternative to the families of anesthesia will usually be provided sedative or relaxant to help them feel comfortable during surgery.
Bier block works by blocking circulation on the limb before injection of anesthetics into the area. Circulation is blocked using a turnstile similar to an inflatable cuff used to measure blood pressure. The cuff is placed on the upper arm or leg and then inflated to cut the circulation to the limb. Furthermore, blood is exhausted from the limb by lifting it over the level of the head or by gently squeezing the limb. The final result is that the limb is almost completely exhausted with blood and fresh blood is prevented from entering the limb with a turnstile.
Furthermore, the anesthetic is given a limb by intravenous injection in the hand or foot. Anesthetics anestrate the entire limb under the turnstile, and the turnstile prevents anesthetics from entering the circulatory system at the same time prevents entering blood into the limb. As soon as the anesthetics manifests itself, the limb is ready for operation.
After the operation is completed, the turnstile is released and removed, allowing you to enter the limb and the remaining anestEthics to enter the circulatory system and be metabolized by the body. The technique of bird pain treatment is only suitable for short surgery, as the prevention of blood in the limb means that oxygen is not supplied to tissues. In order to prevent oxygen starvation in the limb damage, the block can remain in place for more than 60 to 90 minutes.
Some people cannot undergo Bier block due to factors that increase the risks of the procedure. These include allergies to local anesthetic drugs, the use of blood thinning drugs and some diseases such as sickle -shaped diseases and kidney disease. In addition, someone who previously had a blood clot in the limb of the limb to be able to safely undergo this procedure. Because allergies, medicines and diseases can increase risks, it is important that the patient tells his doctor about all these factors, even if they seem smaller.
