Examples of Local Anaesthetic Effects in the Clinical Setting

An example of the effect of anaesthetics on nerve fibres is seen in profound epidural block during labour.

Ideally, the anaesthesia should spare the motor function. However, patients, not infrequently, complain of leg weakness.

Checking that they can stand, and walk safely, after epidural is an essential part of the aftercare for the block.

In the ED, muscle weakness is common during intravenous regional anaesthesia (IVRA/Bier’s block), and the patient is often unable to safely control the affected area, for example, an arm, for a time after the procedure.

The length of time this effect lasts depends on the dose and agent used but is usually about 1-2 hours after release of the tourniquet.
