The probe is nasogastric. Feeding through nasogastric tube

The nasogastric probe is a special device intended for human enteral nutrition. It is necessary in cases when he himself can not eat. Such an introduction of food is required in case of trauma or edema of the tongue. Also, the food is thus carried out with damage to the pharynx, larynx or esophagus, with mental disorders of the person associated with refusal to eat.

The introduction of food through a probe may be necessary when the patient is unconscious. There are contraindications for this method of food intake - it is a peptic ulcer of the stomach at the time of its aggravation. In addition to introducing food through the nasogastric tube, you can take medication. All manipulations should be under the strict guidance of a physician.

How to insert a probe?

In order to enter a nasogastric tube to the patient, it is first necessary to make marks on it. Also check the nasal passages of the person. If the patient is unconscious, the probe is inserted in the lying position, his head is turned to the side. The nasogastric tube can be left for 3 weeks.

Preparation for the procedure

1. It is necessary for the doctor to establish a trusting relationship with the patient or with his relatives.
2. The doctor should tell the patient the purpose of the upcoming procedure and familiarize him with what food he will be given. Also the doctor should tell about the stages of the forthcoming procedure.
3. The room should be ventilated beforehand.
4. The next stage of preparation for probe insertion is the measurement of the distance from the throat to the stomach. For this, the patient must sit straight. Then the doctor should make a measurement. There is an alternative way to calculate the distance to the stomach, for this it is necessary to take away from the growth of a person 100 cm.
5. In order to nasogastric tube easily entered the stomach, it is recommended to moisten it in a solution of "Furacilin". The solution is diluted in a ratio of 1 to 2000. The nasogastric tube is wetted to the deposited mark.
6. Then you should put the patient on the couch. He lies on his back. A pillow is placed under your head. It is necessary to make sure that the head was slightly inclined. This position will ensure free insertion of the probe into the nasopharynx. A napkin is placed on the patient's chest.

How is the probe inserted?

The doctor should carry out this procedure with gloves.

1. The probe is inserted into the nasal passage of the patient by 15 centimeters. Next, you should put the patient in a half-lying position. Then you should tell him to swallow the probe. It should be that a person assumes a position in which the instrument will freely enter the stomach.
2. Then the air is pumped into Jan's syringe. Then it joins the probe and is injected into the stomach. You can hear specific sounds that are evidence that everything is done right.
3. In order to prevent leakage of liquid, after the syringe is disconnected, a clamp is applied to the probe. The outer end is placed in the tray.
4. Next, fix the probe. For this, a bandage is wound around the patient's face and head.
5. The next step in the procedure is to remove the clamp and attach the funnel.

Feeding through nasogastric tube

The probe goes down to the level of the stomach. It should not be allowed to get air there. For this, the funnel tilts and is filled with food. The food should be warm, its temperature should be 38-40 degrees. After the funnel is filled with food, it is gradually raised up until the food is left only in the neck of the funnel. Then the funnel again goes down to the level of the stomach. Then it is filled with food, the process is repeated in a similar way. After the introduction of all food, boiled water or tea is poured into the probe. The feeding procedure is simple through a nasogastric tube. The algorithm is quite simple.

After the food input is finished and the probe is rinsed, a clamp should be inserted at the end of the probe. Next, remove the funnel. After the tip of the probe is wrapped with a sterile napkin or placed in a tray, or you can fix it on the patient's neck. Leave in this condition until the next meal.

Nasogastric probe characteristics

The nasogastric tube is made of polyvinyl chloride. This material has a transparent color. It has the property of thermoplasticity. This means that under the influence of warm tissues, it softens. Also modern probes are equipped with additional characteristics, which greatly facilitate the process of use. These include the radiopaque line, which is present along the entire length of the probe. In some models, the side holes are arranged in a special way. This is done in order to reduce the risk of dumping syndrome. The probes are provided with connectors that interact well with the dispensing feeders. Also modern connectors have special plugs. They, if necessary, are hermetically sealed. Thanks to these plugs, you can not use a clamp.

At first glance, such modifications of the manufacturers seem insignificant, but the use and setting of the nasogastric tube are much easier.

Children's Probe

The principle of operation of the probes is the same. But children have their own characteristics. It should be said that they can also be used for an adult. Children's probes are also made of high quality PVC. They are absolutely harmless, do not cause allergic reactions and can be used up to 3 weeks. Children's probes have a soft rounded end. This characteristic ensures good probe entry and protects against getting any injuries while entering. The ingestion of a probe with a soft tip is painless.

There are also side openings at the end, through which the patient feeds through the nasogastric tube, and nutrients enter the stomach. Children's models are equipped with connectors that can tightly and hermetically close, as well as special adapters for connecting syringes and funnels. Also, the probes have a radiopaque band with marks in centimeters. This allows you to determine the depth at which the probe is located.

Some manufacturers produce tools with color coding. That is, a certain color has a fixed diameter and size. Thanks to the color coding, medical personnel can easily find out which probe is suitable for a particular person. The encoding tables are applied to the tools.

Conclusion
