What are the prerequisites for liver biopsy needle aspiration?

1. Unable to make a clear diagnosis

When the patient cannot be clearly diagnosed, it is necessary to conduct liver biopsy, because liver biopsy is the gold standard for the diagnosis of pathological changes in the liver tissue. When the disease cannot be determined, tissue biopsy is needed to confirm the disease and even help the patient to judge the progression of the disease. Serious diseases such as hepatitis, cirrhosis or liver cancer can be diagnosed effectively by liver biopsy. Liver biopsies can be injurious, so they are generally not considered when other tests can be used to determine disease.

2. Ensure the mental state of patients

Do a liver biopsy before, still need to make sure that the patient's mental state, it is an important prerequisite for, because, for patients with liver biopsy is can cause trauma to the patient, at this stage if hypertension patients, or because the mood fluctuation is too big, can't cooperate with the doctor in puncture, may directly damage internal organs. Therefore, it is called to stabilize the patient's state of mind, avoid excessive tension of patients, and ensure the smooth progress of the examination.

3. Perform preoperative examination

Liver puncture biopsy is a special examination method, so it is necessary to judge the patient's condition through other preliminary examinations before the examination, otherwise there may be accidents in the process of puncture biopsy. First of all, patients should be helped to carry out routine blood group examination, so as to determine the coagulation function or blood disease problems of patients. In addition, medical imaging examination and electrocardiogram examination are also needed to comprehensively evaluate the visceral function of patients.

4. Empty your urine

Before the liver biopsy, the patient needs to empty the urine, because the patient still has urine in the bladder, it is easy to be stimulated during the liver biopsy. The test also requires the use of anesthesia, which can affect the sphincter and lead to incontinence, so it is important to empty urine and relax.

5. Monitor physical signs

Patients' physical signs are monitored mainly to prevent significant changes in patients' physical signs when unexpected situations occur during the operation of liver biopsy, such as patients being too nervous or causing stress reactions. If problems cannot be found in the process of puncture, it may cause disease or even shock of the patient, so it is necessary to monitor the physical signs to perform liver biopsy.

Liver biopsy is not a kind of examination that can be conducted directly in a short time. Liver biopsy is special, which will not only cause damage, but also have many risks in the examination process. Therefore, it is necessary to meet the prerequisite conditions before liver biopsy can be selected. Patients undergoing liver puncture also need to be well prepared, because liver puncture is generally required only for complicated or serious diseases, and they also need to actively cooperate with doctors for treatment after examination.
