Position the patient during intubation, clean and lubricate the nasal cavity. Tilt the patient's head back and insert the gastric tube at an angle of 60° to the nostrils, and continue to insert to the nasopharynx; when the gastric tube is inserted to 15 CM (eclipsing the pharynx), inject 1-2 ML of sterilized paraffin oil along the outer wall of the gastric tube, and hold the patient's head up so that the lower jaw presses against the chest wall to increase the curvature of the pharynx, so that the gastric tube can slide along the back wall and enter the esophagus smoothly through the pharynx. At this time, the patient was asked to swallow while the gastric tube was slowly inserted to the desired length and then fixed. Afterwards, check whether the tube is in the stomach.

After successful insertion of the gastric tube, the tube should be secured properly. The procedure is as follows.

First mark the nostril with a strip of tape about 3cm long around the tube twice, then cross a 6-7cm tape over it to fix the nasal area, then tie a knot around the tube at the nostril with a prepared cloth tape about 50-60cm long (tape width 1.5cm) (do not interfere with the drainage of the tube when tying the knot), then wrap the tape around the patient's head on both sides. A live knot is tied on one side to strengthen the role of fixed gastric tube.

In addition to mastering the whole process, Z is better to go to the hospital to train the nurses to ensure the safety and success of intubation and to prevent sequelae such as mucosal damage to the patient and vocal cord breakage.
