Ultrasound is a method of examining internal organs, based on the interpretation of ultrasound signals returned from the scanned organ. When using modern scanners, this method is one of the most accurate and informative diagnostic methods.
If we recall the school physics course, it will become clear that ultrasonic waves propagate weakly in the air and at the same time are strongly scattered. But water, on the contrary, is an ideal medium for the propagation of this type of radiation. Therefore, preparation for an ultrasound scan, as a rule, consists in measures to get rid of the presence of gases and air in the area of the scanned organ. So, for example, when diagnosing the condition of the bladder, you need to ensure that it is as full as possible. Thus, there are certain rules, the implementation of which will guarantee the receipt of accurate results during ultrasound examinations.
So, preparation for ultrasound of organs that are located in the abdominal cavity consists in following a certain diet. Three days before the date of the study, you need to remove products from your menu such as fresh vegetables and fruits, milk, brown bread. At the same time, you need to start taking activated charcoal tablets (2-4 pieces each) or take the Espumisan preparation according to the scheme described in the instructions for the medicine. If digestive disorders (for example, constipation) are noted, then perhaps the doctor will prescribe Festal-type drugs. However, this issue must be addressed precisely with the doctor. In two days you need to do a cleansing enema. Note! It is two days before the scheduled procedure, and not the day before.
If the ultrasound procedure is scheduled for the morning, then the last meal before it should occur before 19 hours of the previous day. In the event that a doctor’s appointment is scheduled for the afternoon, that is, the last time is needed ten hours before the procedure.
If the study of organs located in the abdominal cavity includes determining the state of the functions of the gallbladder, then the preparation for ultrasound is carried out in exactly the same way. The only difference is that for the procedure you need to take 200 ml of cream with a fat content of 10% or half a liter of kefir (fat content of 3.2%). Those who can not tolerate dairy products, you can replace them with two fresh yolks from chicken eggs.
Preparation for pelvic ultrasound , which is carried out transvaginally in women and transrectally in men, consists of a cleansing enema, which is done on the night before the study. Before the procedure itself, you should visit the toilet to empty the bladder. You can eat and drink as usual.
If scanning of the pelvic organs will be carried out transabdominally, that is, through the abdominal wall, then the preparation for ultrasound is as follows. One and a half hours before the appointed time of the procedure, 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 it becomes difficult to endure urges, and the time for ultrasound has not yet arrived, it is allowed to visit the toilet to relieve excess tension. But then you need to re-drink a certain amount of liquid, so that when the scanning behavior, the filling of the bladder is maximum.
In the same way as described above, you need to prepare for an ultrasound diagnosis of the bladder.
During pregnancy, an ultrasound scan is performed with moderate bladder filling, so preparing for the procedure is to drink half a liter of fluid an hour before the appointed time.
It remains to tell how to prepare for an ultrasound of the kidneys. In this case, it is recommended to adhere to the rules that are recommended when conducting studies of abdominal organs. That is, you need to take measures that will minimize the gas content in the intestine. A kidney test is not performed on an empty stomach, so there is no need to change the food and drink regimen before the procedure.
