In the article entitled: "A primer on nerve agents: what the emergency responder, anesthesiologist, and intensivist needs to know" published in the October 2017 issue of the Journal, Can J Anesth 2017; 64: 1059-1070, two doses in Table 3 contained errors and have now been corrected (and highlighted in bold) in the revised table herein. In the table on page 1064, next to "Pralidoxime/Obidoxime/HI-6", the second column should read: "Pralidoxime- Mild cases: 1-2 g iv over 5-10 min or im". Also in the same row, the third column should read: "Individual doses should not exceed 2 g". The publisher apologizes most sincerely for this error.

Randomized Controlled Trial Comparative Study
Effect of dexamethasone dose and route on the duration of interscalene brachial plexus block for outpatient arthroscopic shoulder surgery: a randomized controlled trial.
Dexamethasone prolongs the duration of interscalene block, but the benefits of higher doses and perineural vs intravenous administration remain unclear. ⋯ Compared with the intravenous route, perineural dexamethasone prolongs the mean interscalene block duration by a small amount that may or may not be clinically significant, regardless of dose. However, the difference in mean block durations between 8 mg and 4 mg of dexamethasone is highly unlikely to be clinically important, regardless of the administration route.
