IVRA overview

IVRA (Intravenous regional anaesthesia), also known as a Bier´s Block, is used to enable the
infused aesthetic to first take effect on the distal part of an extremity. After a period of time, cuff
pressure is applied on the already anesthetized part of the extremity and the cuff is deflated on
the more proximal portion of the limb. To prevent the anaesthetic from leaving the extremity
before it is absorbed by the tissue, it is important to have the cuffs inflated and deflated in the
correct sequence.
Some of the safeguards programmed into the tourniquet for use in an IVRA procedure include:
 A special icon marked" IVRA" is located in the middle of the display. It is used to
program the proximal and distal sides to communicate during the IVRA procedure.
When the "IVRA" icon is activated it changes colour from grey to green to confirm that
the unit is ready for IVRA procedure.
 IVRA procedure button can be engaged, even though one side is inflated, by pressing the
"IVRA" icon and press confirm.
 When both sides of the tourniquet are pressurized, but one side has not yet reached the
set pressure level, only the side that has not yet reached set pressure can be deflated. The
operator can deflate optional side only when both sides are inflated to the set pressure
level.
 The elapsed time will be stopped when both sides are deflated (ref. 3.5).
