Local Analgesia

The word anaesthesia is derived from the Greek words an – "not, without" and aesthetos – "perceptible, able to feel" (Askitopoulou et al., 2000). Local anaesthesia (LA) is a technique used to render a part of the body insensitive to pain without affecting consciousness (Jankovic, 2004). Local anaesthetics are used to prevent acute pain and treat the symptoms of chronic pain (Yanagidate and Strichartz, 2007). They may be administered by injection, continuous infusion or topical application.

This resource will cover relevant aspects of physiology and pharmacology pertaining to local anaesthetics. You'll be able to access this resource for 12 months after purchase.

Aims and Objectives

The objectives of this resource are to review:

• How local anaesthetics work
• How to work out the maximum safe dosages
• The anatomy of lower limb blocks.

Some of the statements in the literature are open to debate. I hope that this activity will stimulate your own review of the articles and books written on the subject of LA.
