What is the terrible thing about atelectasis?

If the alveoli are not opened and there is no gas exchange, it means that the patient is severely hypoxia, or even death from asphyxiation. The symptoms of hypoxia and asphyxiation are called respiratory distress syndrome, which is called RDS in English. In adult patients, it is called adult RDS, referred to as ARDS, and add A. The respiratory distress syndrome in neonates is NRDS, and add N. Why do the two separate? Because the causes of respiratory distress syndrome in adults and neonates are different.

Adult ARDS, which also gave an example of SARS, which left a deep impression on us, is the main cause of severe infection. After severe infection, the virus in the lungs of patients with severe infection caused a large number of alveolar surfactant, PS, to be inactivated, and the alveolar collapsed.

At the same time, a large amount of mucus can be generated to block the bronchial inside, causing mechanical obstruction of the bronchial and ultimately causing severe hypoxia to die.

The treatment plan must first fight the infection. The effect of anti-infection without a specific drug against a certain virus can only be greatly reduced. The doctor's only methods are physical solutions such as bronchoscopy and back-cuffing sputum. These remaining life-saving methods have become particularly important in the rescue of such patients. Therefore, a large number of nurses are needed in this ward to assist in the rescue. The rest can only be achieved by relying on the patient's own immune system to fight the infection. However, relying on the patient's own immune system to fight the infection has another fatal point, which is the immune storm we can hear from the doctors, and it is also one of the important causes of death of this type of patient.

It can be seen that for adult patients with respiratory distress syndrome, medical methods are limited at this stage, which makes clinicians very afraid. When encountering new respiratory virus infections such as SARS, they can only use more distant and ancient methods such as isolation. There is no way, there is no cure.

In addition to infection, respiratory distress symptoms in adults can include factors such as trauma and foreign body inhalation. The process is also relatively dangerous and has a high mortality rate.

In comparison, NRDS, neonatal respiratory distress syndrome mainly occurs in premature babies. The cause of this type of child is relatively single and seems to be easier to treat.

To understand the source of respiratory distress syndrome in newborns, we must first understand the mechanism of normal babies leaving the mother. First, when the fetus does not breathe in the mother's uterus, the lungs are not inflated. After birth, the baby needs to rely on the alveolar surfactant given by the mother to automatically inflate the baby's lungs. Because premature babies leave the mother early and cannot receive gifts from the mother, the alveoli cannot inflate and open, resulting in difficulty in breathing.

Going back to the lung-enhancing acupuncture point that Dr. Hu mentioned at the beginning of the discussion, the most commonly used drug in clinical practice is hormone drugs such as dexamethasone. It uses this mechanism of action to induce fetal lung type 2 cells to produce alveolar surfactant PS, and ultimately avoid white lungs and respiratory distress.

The current situation is an emergency. The doctor was unable to give the mother a lung injection in advance. In this way, the baby born early had symptoms of respiratory distress, as Dr. Hu said, as expected by medical staff.

Since you know that the baby lacks this thing, it causes respiratory distress, can you directly inject alveolar surfactant into the baby? Of course. Question. Where is this thing in the small health center?

This type of medicine is expensive. Generally, hospitals do not have neonatal departments and will not have such specialized precious medicines.
