p. 836. Local and regional anaesthesialocked

  • Aidan O’Donnell

Abstract

‘Local and regional anaesthesia’ describes the family of techniques which can provide anaesthesia by interrupting the function of the nerves themselves, without affecting consciousness and this includes local anaesthetics administered via the skin or digestion and regional anaesthetics given via injection or blockade. Local anaesthetics are absorbed poorly through intact skin so that feeling the effects of them applied as creams or gels is a slow process. Regional anaesthesia can be achieved through injecting a local anaesthetic drug around a nerve. Spinal anaesthesia provides a dense block of all spinal cord function below the level of the block. Injection of local anaesthetic into the epidural space creates a less dense block than a spinal.
