We explore three claims about reversal of neuromuscular blockade.  1. Location of train-of-four assessment matters 2. Train-of-four is unnecessary with "sufficient" time from the last dose  3. Fade can be discriminated by tactile assessment Our guest today is Dr. Daniel Saddawi-Konefka of the Massachusetts General Hospital.    Full show notes available at depthofanesthesia.com.  Recommend a guest or topic at [email protected] or tweet us @DepthAnesthesia.  Rate us on iTunes.  -- References Arain Sr, Kern S, Ficke DJ, Ebert TJ.
