Why do you take chest radiographs with fever? Is it crazy for the hospital to think about money?

For many patients, this kind of situation is really not uncommon: [I just have a fever, and the doctors who went to the hospital prescribed chest radiographs and so on without saying a few words. The doctors now are really incompetent and dirty, and they must be trying to earn examination fees.] But is this really the case? Without gossip, since the question mentions fever and chest radiograph, let’s discuss them from these two aspects.

First of all, patients who come to see a doctor because of fever will definitely give many physicians headaches. This does not mean that doctors are not up to standard. You know, this is the heartfelt words of the old professor of internal medicine. In recent years, when SARS and various bird flu are rampant, when a cough and fever patient comes to the hospital, the doctor is still relatively nervous, so there is a fever clinic in a remote corner of the hospital.

Human body temperature is regulated by the body temperature center, And through nerve and body fluid factors, the process of heat generation and heat dissipation is dynamically balanced. When the body is affected by a heat source or caused by various reasons to cause dysfunction of the thermoregulatory center, the body temperature rises beyond the normal range, which is called fever (in common terms, fever is one of the manifestations of the body in the process of resisting to the death when dealing with external invasion, fever is a scientific name, fever is commonly known).

You may have realized that when the body responds to external [stimuli], it will fever in most cases. This is an early warning, so when a fever patient comes to the hospital, the situation faced by doctors is far from as simple as the infection the patient thinks.

1. Differential diagnosis

According to different symptoms, doctors should consider respiration, digestion, circulation, urinary tract, movement, nervous system and infectious diseases. The professional term is differential diagnosis.

Step 2: Consultation

Considering all these factors may lead to fever, Doctors must narrow the scope of diagnosis according to other manifestations of patients. This funnel-like thinking enables doctors to finally make a definite diagnosis. The process is the communication between doctors and patients (learning name is inquiry) and further auxiliary examination. Although doctors ask seemingly irrelevant things such as eating and sleeping, in fact, this is a process of moving closer to the correct answer. Where can the outpatient volume of dozens of patients in the morning allow doctors to gossip?

3. Which fever patients need chest radiograph examination

Generally speaking, after general consultation, doctors can reduce the diagnosis to a certain systemic disease: if there are palpitations, precordial pain, dyspnea, etc., it is considered as a circulatory system disease; Digestive system diseases are considered when accompanied by nausea, vomiting, abdominal pain and diarrhea. Infectious diseases will be considered with muscle pain. Accompanied by dizziness, headache, consciousness disorder, consideration of nervous system diseases, etc. Of course, if the above symptoms occur, doctors often not only prescribe chest radiographs. However, if the patient has symptoms such as cough, expectoration, runny nasal discharge and sore throat, that is, when considering respiratory diseases, most doctors will ask the patient to have a chest anteroposterior X-ray examination (commonly known as chest radiographs) to help diagnose the disease.

4. Chest radiograph is what

Chest radiograph refers to chest X-ray examination, X-ray penetrates the human body to form two-dimensional images of human tissue structure. In today’s days when B-ultrasound, CT, MRI and PET/CT are popular, chest radiography still cannot be shaken and stands firm, because it has an irreplaceable position in the observation of lung diseases, pleural effusion, pneumothorax and heart morphology.

5. Characteristics and functions of chest radiographs

When doctors consider that fever is related to respiratory system, Chest radiograph must be the simplest, cheapest, most practical and earliest examination method. From this, doctors can judge which respiratory system disease is caused by lobar pneumonia, bronchopneumonia, lung abscess, tuberculosis and so on, providing the basis for further treatment.

6. Summary

In summary, In fact, fever is very simple in the eyes of ordinary people, but it is difficult for ordinary people to understand the complexity of the etiology hidden behind the actual situation. Not every time a fever doctor will let you take a chest radiograph, since it is natural to have its reason to do a chest radiograph examination. Don’t complain about why doctors want to take a chest radiograph. Don’t underestimate the chest radiograph, small chest radiograph has great use!
