- Preparation of the patient for ultrasound of the gallbladder. The patient should refrain from eating food and water for 8 hours before the study. If fluid intake is necessary, then only water can be given. If the clinical symptomatology is acute, the study is carried out immediately. Children, if the clinical conditions permit, should refrain from eating food and water for 3 hours before the study.
- Position of the patient. Start the study in the patient's position lying on his back: in the future, you may need to rotate the patient to the left side or place it vertically or on all fours.
Apply the gel freely on the upper right quadrant of the abdomen. Subsequently, apply the gel to the upper left quadrant of the abdomen, since, regardless of clinical symptoms, it is necessary to examine both sides of the abdomen.
Carry out a study if the patient experiences breathing on inspiration or with a bulging belly in full breath.
- Select the sensor. Use a 3.5 MHz sensor for adults and 5 MHz for children and thin adults.
- Setting the sensitivity of the device. Start the study by placing the sensor centrally in the upper abdomen (below the xiphoid process). Tilt the sensor to the right until you get a picture of the liver; Adjust the sensitivity to obtain the optimum image.
