What is the preparation for ultrasound?

Ultrasound is a method of examining internal organs, based on decoding the ultrasound signals returned from the scanned organ. With the use of modern scanners, this method is one of the most accurate and informative methods of diagnosis.

If you recall the school course of physics, it becomes clear that ultrasonic waves propagate weakly in the air and are strongly dissipated. But water, on the contrary, is an ideal medium for the propagation of this type of radiation. Therefore, the preparation for ultrasound, as a rule, consists in measures that allow to get rid of the presence of gases and air in the area of the organ being scanned. So, for example, when conducting a diagnosis of the condition of the bladder, you need to ensure that it was as full as possible. Thus, there are certain rules, the implementation of which will guarantee the receipt of accurate results during ultrasound examinations.

So, the preparation for ultrasound of organs that are located in the abdominal cavity, is to observe a certain diet. Three days before the research date, you need to remove from your menu products such as fresh vegetables and fruits, milk, black bread. At the same time, you need to start taking activated carbon tablets (2-4 pieces each) or take Espomizan according to the scheme described in the drug instructions. If digestion disorders are noted (for example, constipation), then, probably, the doctor will prescribe the reception of preparations of the "Festal" type. However, this issue must be solved with the doctor. For two days you need to make a cleansing enema. Note! It was two days before the appointed procedure, and not the day before.

If the ultrasound procedure is scheduled for the morning, the last meal before it should occur before 19 hours of the previous day. In the event that the appointment with the doctor is scheduled for the second half of the day, that is, the last time you need ten hours before the procedure.

If the examination of organs located in the abdominal cavity involves the determination of the state of the gallbladder functions, then the preparation for ultrasound is carried out in exactly the same way. The only difference is that the procedure should take with you 200 ml of cream with 10% fat or half a liter of kefir (fat content 3.2%). Those who can not tolerate dairy products can be replaced with two fresh yolks from chicken eggs.

Preparation for ultrasound of pelvic organs, which is performed transvaginally in women and transrectally in men, consists in carrying out a cleansing enema, which is done for the night before the study. Before the procedure, you should visit the toilet to empty the bladder. You can eat and drink as usual.

If the scan of the pelvic organs is carried out transabdominally, that is, through the abdominal wall, the preparation for ultrasound is as follows. For an hour and a half before the scheduled time, you need to drink about one and a half liters of any liquid. For this study, it is important that the bladder is as full as possible. If you endure urge becomes difficult, and the time of the ultrasound has not yet come, you can visit the toilet to remove excess tension. But then you need to re-drink some amount of liquid, so that when the scan behavior the filling of the bladder was maximum.

In the same way as described above, you need to prepare for an ultrasound diagnosis of the bladder.

During pregnancy, ultrasound is performed with a moderate filling of the bladder, so the preparation for the procedure is to drink half an liter of liquid one hour before the scheduled time.

It remains to tell how to prepare for ultrasound of the kidneys. In this case, it is recommended to adhere to the rules recommended for abdominal examinations. That is, you need to take measures that will minimize the gas content in the intestine. Kidney examination is not performed on an empty stomach, so there is no need to change the food and drinking regimen before the procedure.
