Hazardous Intraoperative Behaviors: What's at Risk?.

AANA Journal  June 2016  Vol. 84, No. 3 155 On Combat Anesthesia To the editor: I was reading the article on combat anesthesia, August 2015, Vol 83, No 4, pages 247-253. There is a comment in the article on page 251, about Role VI care; I believe the authors meant to state Role IV care. Also, in the paragraph on page 250: “In the military, nearly everyone knows his or her blood type; it is on everyone’s dog tag (although it is wrong about 4% to 10% of the time) ...” I did not see the authors’ reference(s) for this statistical data. I was wondering if the authors could provide their reference(s) used for this statement.
