Disposable gastric tubes are usually made of liquid silica gel material. They are used in clinical patients with dysphagia disorder who have lost the ability to eat independently. The gastric tubes are inserted into the stomach by the nasal feeding method to ensure energy intake, nutrition supply and drug treatment. Gastric tube intubation is commonly used in patients with digestive tract conditions such as pancreatitis and intestinal obstruction, as well as those unable to swallow due to nerve damage and other factors
How many cm is the length of the gastric tube?
The length of the gastric tube tube is generally 45-55cm for adults and 20-25cm for children. The specific length is usually determined by the length from the patient’s forehead hairline to the sternal xiphoid process, or the length from the nose tip to the sternal xiphoid process through the earlobe. If stimulant drugs need to be injected through the gastric tube, the gastric tube can be deepened by 10cm to prevent gastrointestinal discomfort caused by the drug, resulting in reflux, aspiration, etc.
How often are gastric tubes replaced?
How often are gastric tubes replaced? The gastric tubes made of ordinary materials are replaced once a week, while those made of polyurethane and silicone are replaced once a month. But if the tube is damaged, broken or blocked, it should be replaced at any time
When feeding nutrition solution or fluid food through the nose, we must pay attention to the amount of nasal feeding, do not feed too much, feed too fast, maintain a uniform speed, to prevent obstruction.
Too much injection in a short time will increase the burden of patients’ gastrointestinal tract, lead to indigestion, and may even induce abdominal pain and diarrhea.
Nasal feeding food should pay attention to balanced nutrition, liquid or semi-liquid diet is recommended. Before nasal feeding, gastric juice can be extracted to help check whether the gastric tube is protruded from the stomach and whether the gastric tube is unobstructed.
Warm water can be injected before nasal feeding to lubricate the lumen, and warm water should also be injected after the completion of nasal feeding to flush the gastric tube, which is helpful to smooth the gastric tube and improve digestion. It is necessary to prevent the presence of food residue in the lumen, which may cause the lumen to become blocked or cause infection after deterioration.
