How do you make a Bier block?

A Bier block essentially consists of injecting local anesthetic solutions into the venous system of an upper or lower extremity that has been exsanguinated by compression or gravity and that has been isolated by means of a tourniquet from the central circulation.

Similarly, it is asked, how do you do a Bier block?


  1. Establish an intravenous (IV) line in the uninvolved extremity.
  2. Draw up and dilute 1% plain Lignocaine (1.5- to 3-mg/kg total Lignocaine dose) for a final concentration of 0.5% Lignocaine.
  3. Place a padded tourniquet and inflate the upper cuff.
  4. Insert a small IV cannula near the pathological lesion and secure it.

Also, is a Bier block safe? In conclusion, the Bier block is a safe, effective, and cost-effective way to provide anesthesia and analgesia for extremity surgeries of short duration. This elegant technique requires minimal additional equipment and can be performed in a variety of clinical environments.

In respect to this, what type of anesthesia is a Bier block?

In experienced hands, it's safe and effective and avoids side effects of general anesthesia. A Bier block is a type of intravenous regional anesthesia that involves administering a local anesthetic into an upper extremity while blocking venous return with an inflated cuff.

How long does it take for a Bier block to wear off?

For example, nerve blocks for hand surgery usually last for 6-8 hours, but a nerve block for pain after total knee replacement can last for 12-24 hours. Medication continuously delivered through a tiny plastic tube (nerve catheter) placed next to the nerve can last for 2-3 days.
