Abstract
Intravenous regional anesthesia (IVRA) or Bier block anesthesia is a common anesthetic technique for surgical procedures on the body’s extremities where a local anesthetic is injected intravenously. The technique usually involves exsanguination, which forces blood out of the extremity, followed by the application of pneumatic tourniquets to safely stop blood flow. The anesthetic agent is introduced into the limb and allowed to set in while tourniquets retain the agent within the desired area. After some time, the tourniquet is depressurized to restore circulation.
The original block has been modified by placing the tourniquet on the forearm The advantages of this modification are decreasing the dose of local anaesthetic drug so, increasing safety, preservation of the function of the hand muscles during the period of surgery and increasing the tolerance of the anesthesia.
The main object of our study was to compare the use of single forearm tourniquet versus the use of the double upper tourniquet during the intravenous regional anesthesia regarding the quality and the efficacy of the block.
