Biers block procedure

Procedure for patients returning for Biers block and manipulation of wrist fractures

There are times when it is not practical for patients with distal radius fractures to undergo Biers block regional anaesthesia and manipulation during their initial attendance.

A protocol has been agreed between the Emergency Department and plaster room staff that describes how these patients should be managed.

Procedure

• A plaster backslab, broad arm sling and appropriate analgesia should be provided.
• The patient should be given an appointment for the following emergency department clinic at 10:00am.
• Plaster room staff should be made aware of the patient’s arrival at the clinic and should inform the emergency clinic nurse of a time that they will be free to assist with the procedure. It is expected that this time should be as close to 11:00am as is practical.
• At the clinic the patient shall be prepared for the procedure, this includes completion of the appropriate documentation, IV cannulation and consenting.
