Intubation by dither-torquing

Intubation by dither-torquing. A. The shaft is torqued counterclockwise while advancing the shaft 10 to 15cm. B. The shaft is torqued clockwise while withdrawing the shaft 10 to 15 cm. Repetition of this cycle encourages the sigmoid to accordionize onto

Intubation by looping
