Bier's block: a change of injection site.
Bier's block or intravenous regional anesthesia is a well-proven technique that is useful in the traumatic setting to provide upper limb anesthesia in the manipulation of distal radial fractures. In this situation, the traditional injection site in the dorsum of the hand can present difficulties with subsequent plaster application and with venous access caused by swelling or pain. One hundred patients were randomly allocated into two groups of 50. The first group was injected into the dorsum of the hand and the second into the antecubital fossa, in each case on the injured side. Effectiveness of anesthesia at both the fractures site and the cuff was assessed using a visual analog scale. Results analyzed using Student's t test, showed no difference in anesthesia between the two groups. In addition, there were fewer technical problems associated with venous access and subsequent plaster application in the antecubital fossa group.
