In the original version, Reference 55 was published incorrectly.

Reference 55, which previously read:

55. Khattab AM, El-Seify ZA, Shaaban A, Radojevic D, Jankovic I. Sevoflurane-emergence agitation: effect of supplementary lowdose oral ketamine premedication in preschool children undergoing dental surgery. Eur J Anaesthesiol. 2010;27(4):353–8.

should read:

55. Khattab AM, El-Seify ZA. Sevoflurane-emergence agitation: effect of supplementary low-dose oral ketamine premedication in preschool children undergoing dental surgery. Saudi J Anaesth. 2009;3:61–6.

The former article was retracted from the European Journal of Anaesthesiology in 2011 as it was found to be a duplicate of the article published in the Saudi Journal of Anaesthesia.
