Intravenous regional anesthesia
Intravenous Regional Anesthesia (pronounced: in-tra-vee-nus ree-juh-nl an-es-thee-zha) is a medical procedure used to numb a specific region of the body, typically an extremity like an arm or leg, to block pain during surgical procedures. This technique is also known as a Bier block, named after August Bier, the German surgeon who first described the procedure in 1908.
Etymology
The term "Intravenous Regional Anesthesia" is derived from the Latin words 'intra' meaning 'within', 'vena' meaning 'vein', and the Greek words 'an-' meaning 'without', and '-esthesia' meaning 'sensation'. The term 'regional' refers to the specific area of the body that is targeted by the anesthesia.
Procedure
Intravenous Regional Anesthesia involves the injection of a local anesthetic, such as lidocaine or bupivacaine, into a vein in the patient's arm or leg. A tourniquet is applied above the injection site to prevent the anesthetic from spreading to the rest of the body, thus ensuring that only the desired region is numbed. The anesthetic is then allowed to circulate within the veins of the targeted region, numbing the area and allowing for pain-free surgical procedures.
