We have enjoyed the special opportunity to work with Nani Clansey, who has always been a delight to work with and has been most informative and supportive in the creation of this fourth edition. In addition, it has been a pleasure working with the extremely competent, efficient, and hardworking assistance of Charlotta Kryhl, Commissioning Editor, and Karthikeyan Murthy, Project Manager, at Elsevier.

 

Also, special thanks to the contributing emergency department medical staff at the University of Vermont who will be taking over full responsibility for updating future editions of this publication.
