Peripheral regional anaesthesia are often used for smaller surgical procedures, like: | |||
* Excisional biopsy of naevi or other skin lesions | |||
* Wedge resection of ingrown toenail | |||
* Suturing of wounds | |||

Infiltration anaesthesia is similar to nerve blocks but differ in that the aim of infiltration anaesthesia is not to anaesthetise the nerve itself, but the nerve endings in a certain area of tissue. [[Local anaesthetic]] is injected directly into and around the area to be anaesthetised, from which it will disperse in the tissue. This is simpler than nerve blocks and preferred for most cases, except for toes and fingers. Infiltration anaesthesia is often used for [[Wound|wounds]] which are to be examined or sutured, or for skin biopsy. | Infiltration anaesthesia is similar to nerve blocks but differ in that the aim of infiltration anaesthesia is not to anaesthetise the nerve itself, but the nerve endings in a certain area of tissue.

Topical anaesthesia refers to applying local anaesthetic topically to the area to be anesthetised, often as a spray or gel. This is useful for the upper airway before laryngoscopy, endoscopy, or intubation, and before bladder catheterisation. Topical anaesthesia is especially useful in children. | Topical anaesthesia refers to applying local anaesthetic topically to the area to be anesthetised, often as a spray or gel.

Intravenous regional anaesthesia (IVRA) or Bier block involves isolating an exsanguinated limb from the circulation with a tourniquet and injecting the local anaesthetic intravenously. It’s simple, safe, and effective, and especially suitable for short procedures and outpatient surgery.<noinclude>[[Category:Anaesthesiology]] | Intravenous regional anaesthesia (IVRA) or Bier block involves isolating an exsanguinated limb from the circulation with a tourniquet and injecting the local anaesthetic intravenously.
