In the article on page 93 of the July 2012 issue, there are three places where errors occur related to the number of twitches given:

  1. In the abstract (p. 93), the second sentence of the Methods section should read: “To reverse a deep blockade (12 or fewer posttetanic twitches), a dose of sugammadex of 4 mg/kg ideal body weight (IBW) was followed by a second dose of 2 mg/kg IBW if the TOFR was less than 0.9 after 3 min.”

  2. In the section Neuromuscular Monitoring and Sugammadex Administration Protocol (p. 94), the second sentence should read: “To confirm a deep blockade, we applied a titanic stimulus (of 50 Hz for 5 s) and counted the posttetanic twitches 3 s later; the block was considered deep if zero to 12 posttetanic twitches were detected.”

  3. In figure 1 (p. 95), text should read: “Deep Blockade (from PTC = 0 to 12 Twitches)” instead of “Deep Blockade (from PTC = 0 to 2 Twitches).”

The publisher regrets these errors.
