Intubation of the larynx.
Fig. 487
The tube in the pharynx.
A suitable tube having been selected, a strong thread is passed through a small opening near its head, thus affording means for withdrawing it should there be need before it is finally left in its resting place. The particular obturator meant for the tube to be used is then firmly fastened upon the handle and over it the tube is slipped. The instrument should then be tested to make sure that disengagement of the tube will easily take place. Everything being ready, the patient is then held in the arms and on the lap of an assistant, in the position indicated in [Fig. 486]. The individual holding the patient should be perfectly reliable in the matter of presence of mind and self-control, for a great deal depends upon having a child firmly and properly held during the moment of intubation. The arms and hands of the patient should be well wrapped with a towel and firmly held by the side of the chest, for the temptation is inevitable to put the hand to the mouth and interfere with the operator. A second assistant should stand above and behind, holding the mouth-gag in position, as represented, and steadying it as well as the head. It is necessary that the mouth-gag be held firmly in place, for if it should become disengaged the child may bite the operator’s finger.
