In recent years, medical technology has advanced rapidly, and ultrasound is now given great importance and widely used in clinical diagnosis and treatment. This high-frequency sound wave has significant advantages in diagnosing many types of diseases and monitoring fetuses during pregnancy. It has remarkable safety features and wide range of indications. However, in certain circumstances, patients need to fast or holding urine, which aroused public confusion and discussion.
In medical practice, for patients undergoing segmented ultrasound examination of the abdomen and intestines, we recommend fasting for more than 8 hours before the examination to reduce food interference with bile and other secretory factors that affect image quality. However, experts remind that eating will reduce the size of the gallbladder, leading to unclear distinction between pathological and physiological states, thus affecting the condition of the gallbladder cavity and the judgment of the condition. In order to ensure the accuracy of the test results, we encourage the subjects to eat low-fat and easy-to-digest foods that night. If necessary, you can also consider using digestive drugs to help empty the stomach.
In the process of screening and diagnosis of related diseases, some special projects need to pay special attention to preparation work, especially as mentioned BladderPerfusion water intake operation and other inspection items related to the urinary system and gynecology. Appropriate urination can reduce the interference of intestinal gas on medical image analysis and improve image quality. For example, in gynecological B-mode ultrasound imaging, properly filling the bladder can push open the surrounding intestinal wall, allowing the uterus and its appendages to be more clearly exposed. However, excessive or insufficient urine output will affect the accuracy of the displayed images and increase the difficulty of examination; for postpartum Ultrasound examination requires an appropriate amount of urine accumulation in the early stages of pregnancy (that is, before 11 weeks). However, once the baby grows beyond the 11th week, this link no longer requires special conduct.
Medical experts said that gynecological ultrasound scan requires the patient to store at least nearly 300 to 400 ml of urine in the bladder. To achieve this, it is usually recommended to drink 500 to 800 ml of water and rest quietly for two hours before the examination. During this time, avoid substituting tea, coffee, or other caffeinated beverages for pure water to suppress the urge to urinate. These beverage ingredients may cause abdominal pressure disorders, thereby affecting the clarity and accuracy of ultrasound images.
The ultrasonic monitoring instrument used by most medical institutions today is a high-frequency color Doppler ultrasound diagnosis and treatment system (often referred to as \”color ultrasound\”). The double-blue color accurately identifies blood flow routes and provides clear and transparent two-dimensional structural information, allowing patients and their families to understand the progress of the disease visually and perceptibly.
Before conducting a comprehensive body organ examination, senior doctors recommend that we first keep an empty stomach to reserve sufficient energy, and then eat a regular diet. After that, you need to hold your urine for special examination. For female patients, when undergoing transvaginal ultrasound examination, they need to empty their urine in advance and remember to avoid menstrual periods to ensure the accuracy of diagnostic results.
It is true that preset planning may cause trouble to some patients, but its primary focus is to ensure the accuracy and stability of ultrasound diagnosis. Only fineOnly intensive examinations can help doctors deepen their understanding of the patient\’s condition and formulate a detailed treatment plan accordingly.
In the field of modern medicine, ultrasonic examination technology, which is safe, non-invasive and highly accurate, has been widely used. To ensure the accuracy and reliability of assessment results, it is crucial to strictly follow the instructions of medical staff. Through this, we can help doctors formulate diagnosis and treatment plans and treatment strategies for patients more accurately.
We sincerely invite colleagues in the industry to discuss the key issues of ultrasonic examination and preparation, and share practical experiences and insights. If you have any questions or exciting stories about the above topics, please leave a message and share them in the comment area. We hope to take this opportunity to promote the popularization of universal scientific knowledge and increase public awareness of the necessity and importance of ultrasound examinations.
