Figure 1: (a) Length of the 8.0 mm internal diameter endotracheal tube is seen to be approximately 36 cm, and when gum elastic bougie is inserted appropriately, 24-25 cm of it projects outside the endotracheal tube. The figure also shows a shortened endotracheal tube of 8.0 mm internal diameter, which is cut at 24 cm mark. This allows for nearly 36 cm of the gum elastic bougie projecting out of the endotracheal tube. (b) A 4.5 mm internal diameter uncuffed endotracheal tube snugly fits the distal end of the gum elastic bougie thus lengthening the gum elastic bougie to >80 cm
