1, In neurological department of internal medicine, common dysphagia in patients with bulbar palsy occurred in patients, stroke is one of the common causes of. In order to ensure the nutritional requirements, maintain water, electrolyte balance and application of drugs, promote disease recovery, the need for the nasal feeding. But it often brings to the patient discomfort, increase the patient's mental pressure and fear. Through the humanistic nursing care, the patients in the psychological, social, spiritual satisfaction and comfort in the state, reduce or reduce the degree of adaptation, eliminating the patient's fear. Through the system to evaluate patients, improve the success rate of intubation, shorten the operation time, relieve pain, improve the cure rate of the disease.

2, In the Department of internal medicine, common in intestinal obstruction, severe acute pancreatitis, nasogastric decompression is an important measure in the treatment of intestinal obstruction, gastrointestinal decompression through the gas suction in the gastrointestinal tract and liquid, relieve abdominal distention, reduce intestinal cavity pressure, reduce intestinal bacteria and toxins, improve local disease and systemic conditions. The gastrointestinal decompression insertion depth directly affect the drainage effect and improve the degree of patients with abdominal distension.

According to clinical observation, the traditional nasogastric tube insertion depth of 45 ~ 55cm, part of the patients drainage quantity is little, abdominal distension and no obvious improvement.

Intubation by traditional method, from the ear to the tip of the nose to the xiphoid, insert length is 45 ~ 55cm, the observation group from the tip of the nose to the ear lobe and fortune to the xiphoid, insertion length of 55 ~ 68cm. Human anatomy, esophageal length 25 ~ 30cm, nose pharynx length is 12cm, length is 8cm, the total length of 45 ~ 50cm, gastric distal side hole from top distance is 2.5, conventional intubation length, from the analysis of anatomy, the tube side hole can not be fully into the stomach, gastric tube top only Ben under the door, the most reach the body of stomach, the stomach liquid cannot be the umbrella out, influence the effect of gastrointestinal decompression. Gastrointestinal reduction, tube side hole all into the stomach at the depth of 55 ~ 60cm, to make the tube side bar completely reaching the stomach, play a good pressure reducing effect, intubation depth must be more than 55cm. The length of intubation increased 13cm, up to 55 ~ 68cm, the bottom tube top up to the stomach, gastric tube side tie all in the stomach, make gastric drainage volume increased, abdominal distension in patients with significantly reduced, the gastrointestinal decompression tube to a depth of 55 ~ 68cm, drainage effect is better than that of conventional intubation depth, the patient's clinical symptoms also improved obviously.

3, The number of senile diseases such as senile dementia, lack of late Ca cannot be self eaters.
