Regional nerve blocks. Part 1--An introduction.
Sustained nerve trauma is unlikely in a block. Local anaesthetics need time to work--the bigger the nerve the longer they need. Always perform a nerve block on an awake patient. Very young children and the frail elderly are more susceptible to cardiac toxicity. When used appropriately adrenaline slows the uptake of local anaesthetic into plasma.
