Following publication of this article, the PRAN investigators informed the authors that a recent audit for a different manuscript had revealed two updates to the database. For Case 1 presented in Table 3, the patient received lipid emulsion for treatment, not midazolam. In addition, the age for Case 2 in Table 3 is 13 yr and not 1 yr. This information was not provided to the authors in the original dataset. The second sentence of the fourth paragraph in the Methods section should read, ‘All single shot nerve blocks performed between April 1, 2007 and May 31, 2015 (all available audited data) were analysed.’ The first two sentences in Paragraph 3 of the Results section should read, ‘The use of ultrasound for block placement was reported in the majority of blocks, 30 606 out of 40 121 (76%). The use of ultrasound for block placement increased over the duration of the study years with 188 out of 611 (31%) blocks placed with ultrasound in 2007 compared with 3200 out of 3663 (87%) in 2015 (P<0.001).’ These changes do not affect the analysis, main results, or conclusions of the paper. In addition, ‘and the PRAN Investigators’ was omitted following the authors’ names. The authors regret these errors, and thank the PRAN investigators for notifying us of the necessary corrections. The authors would like to apologise for any inconvenience caused.
