The National Service Framework for Children [DoH, 2003] encourages the development of guidelines and the use of audit to ensure that the treatment and care offered to children is continually improving. Thus an audit was undertaken in a South London Day Surgery Unit to ascertain the fasting times of children undergoing dental treatment under general anaesthetic. A literature search identified that clear fluids can be safely ingested until two hours prior to general anaesthesia and the Trust guidelines were found to be congruent with current evidence.
