Duodenal sounding: technique of performance, indications for prescribing
Not always blood, urine or feces can provide reliable information about the patient's health. In such cases special diagnostic manipulations are assigned.
Description of procedure
One of these is duodenal sounding, the technique of performing which requires some preparatory measures.
This procedure is prescribed in the presence of diseases of the gallbladder, as well as the liver.
How is duodenal sounding done? The algorithm for carrying it out is to examine the contents of the duodenum. From it extracted intestinal, gastric and pancreatic juices, as well as bile mixture.
Duodenal sounding, reviews of which are mostly positive, helps to clarify the situation with inflammatory lesions of the gallbladder and with diseases of the liver and bile ducts. Also with its help it is possible to detect the presence of parasites in the body.
Do not use drugs before sensing
Before carrying out duodenal probing, the patient must be prepared for this manipulation. About a week before this, do not recommend taking certain medications:
- some antispasmodics;
- medications that improve digestion.
Ration and Meals
If duodenal sounding is prescribed, the technique of performing it should be strictly followed. Fasting is performed. The last meal should take place the previous evening, no later than 19:00.It is desirable that the dinner was easy. It is strictly forbidden to eat foods that can cause rapid gassing in the intestine. These include:
- Borodino bread;
- dairy products.
In the evening, the patient is prescribed the drug "Atropine", which needs to take 8 drops. In some cases, it is administered subcutaneously. Also use water in a warm form, in which add 30 g of xylitol.
Preparation in the morning
Duodenal sounding, the algorithm of which starts in the morning, lasts from three to four hours. First of all, the patient should tell the sequence of the procedure. Also, explain why it is meant to dispel any doubts about the need for this manipulation.
After this, the patient is placed on a comfortable chair in the tilt-room with a bowed head. In the hands is given a special tray, designed for saliva, and a chest is placed on the chest area.
If a person who will be given this procedure has dentures, they must be removed.
Beginning of the procedure
After these preparations, the specialist takes a sterile duodenal probe and moisturizes his end with water. After doing this, he takes the probe in his right hand in a place that is about fifteen centimeters from the olive tree. In the left hand is the second end.
The probe starts to enter further. In the open mouth in the area of the root of the tongue, the olive is placed, which the patient, after making a swallowing movement, must move to the esophagus with the help of a specialist.
To avoid a vomiting reflex, the patient should breathe deeply nose. If at this time the process of breathing passes without any obstacles, this is a sign that the duodenal probe has entered the esophagus.
Swallowing the patient, the patient moves the probe deeper until it reaches the stomach. To find out, the specialist attaches a special syringe. If the container is filled with a turbid liquid, this means that the probe is in place.
On the adaptation there are special marks, which determine where the olive is. A fourth strip is enough for the stomach. If you need to penetrate deeper, up to the seventh risk, then further advancement is carried out in an upright position. It is advisable at this time to walk slowly.
If probing of the duodenum is required, then the olive should be swallowed up to the ninth strip. To make it easier, the patient is placed on the couch on the left side. Under the pelvic area, a small roller is placed, and under the ribs a warm water bottle.
Duodenal sounding. Technique for performing
When the olive is in place, the free end of the probe is lowered into the jar. She stands on a small table near the tripod at the head of the patient. There are also placed test tubes in which materials for research are collected.
As soon as a clear liquid of a yellow hue is released, the end of the probe, which is free, is immediately placed in the first jar. It should collect up to forty milliliters of bile. It takes about half an hour.
When the required amount of fluid in the first tube is collected, a specialist enters a 25% solution of magnesium sulfate into the probe. The drug should be heated somewhere to forty degrees. Then clamp the clamp or knot the free end of the probe and leave it for about ten minutes.
After this time, the free end of the probe is released and lowered into the jar. As soon as the secretion of thick dark olive bile begins, the device is removed from the container and placed in a second test tube. The material for analysis needs somewhere around sixty milliliters, it will take another half an hour to collect it.
After this time, the free end of the probe is again placed by a specialist in the jar and, as soon as the hepatic bile secretion begins, which has a bright yellow color, it is immediately transferred to the third tube. It will take about twenty milliliters to collect liquid.
When the duodenal probing of the gallbladder ends, the specialist leads the patient to a sitting position, after which the probe is taken out. After this, the researcher is given an antiseptic or water to rinse the mouth.
Immediately after manipulation, the patient is asked about the state of health. After that, he is delivered to the ward, where he waits for breakfast left in the morning. To depart from the procedure, the patient needs a bed rest and complete rest.
