 It is not absolutely necessary to use a gag, but its use facilitates keeping the jaws open to allow passage of an ET tube.However, there is generally no need to use a gag in neonatal foals as they have minimal jaw tone.

 The gag is fitted between the upper and lower incisors and care must be taken to avoid pressure on the hard palate.

 A variety of gags may be purchased from commercial vendors or a gag may be fashioned from a piece of PVC pipe (see Figures 4.6 and 4.7).PVC gags are lightweight and unobtrusive.
