I tended to attempt intubation prematurely… 3 minutes feels like a long time. That’s why, when starting at least, the second person came along and stuck the tube down with ease due to the improved intubating conditions i.e. muscle relaxation! As for sux, if possible, wait for longer than ‘end of fasciculations’ . JC enforces timing 60 seconds! Especially important in difficult intubations in elective situations.
