Introduction to the use of gastric tube
Position the patient for tube insertion, 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 the nasopharynx; when the gastric tube is inserted to 15 CM (euphragus), 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 through the pharynx smoothly. 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.
Mark the nostril with a strip of tape about 3 cm long around the tube twice, then cross it with a 6-7 cm tape to fix the nasal flank, then tie a knot around the tube with a prepared cloth tape about 50-60 cm long (tape width 1.5 cm) at the nostril (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. Tie a live knot on one side to strengthen the role of fixed gastric tube.
