    What is so scary about atelectasis?

    The alveoli no longer open and there is no gas exchange, indicating that the patient is severely hypoxic and may even die of suffocation.  This symptom of hypoxic suffocation is called respiratory distress syndrome, or RDS in English.  In adult patients, it is called adult type rds, or ards for short, with an a added.  Neonatal respiratory distress syndrome is nrds, add an n.  Why should the two be separated? Because the causes of respiratory distress syndrome in adults and newborns are not the same.

    Adult ards, the same example of SARS that left a deep impression on us, the main cause is severe infection.  In the lungs of patients with severe infection, the virus inactivates a large amount of alveolar surfactant (PS), causing the alveoli to collapse.

    At the same time, a large amount of mucus is produced, which can block the bronchus and cause mechanical obstruction of the bronchus that cannot be eliminated, eventually causing the patient to die from severe hypoxia.

    The treatment plan is definitely to fight the infection first.  In the absence of specific drugs for a certain virus, the effectiveness of anti-infection can only be greatly reduced. Doctors only have physical solutions such as bronchoscopy and back patting to cough up sputum.  These remaining life-saving methods have become particularly important in the rescue of such patients.  Therefore, this kind of ward requires a large number of nurses to assist in rescue operations.  For the rest, the patient's own immune system can only fight the infection.  But relying on the patient's own immune system to fight infection has another fatal side, which is what doctors call an immune storm, which is also one of the important causes of death for such patients.

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

    In addition to infection, respiratory distress syndrome in adults can be caused by trauma, foreign body inhalation and other factors.  The process is also dangerous and has a high mortality rate.

    In comparison, nrds, neonatal respiratory distress syndrome mainly occurs in premature infants.  The cause of this disease in children is relatively single when traced back, and it appears to be relatively easy to treat.

    To understand the origin of neonatal respiratory distress syndrome, we must first understand the mechanism by which normal babies leave their mothers.  First of all, when the fetus is in the mother's womb, it does not breathe on its own. The lungs are atelectatic and the alveoli are not inflated.  After birth, the baby needs alveolar surfactant from the mother to allow the baby's lungs to automatically inflate.  Premature babies leave the mother's body early and do not receive gifts from the mother. They lack this substance and their alveoli cannot inflate and open, causing difficulty in breathing.

    Going back to the lung-stimulating needles mentioned by Dr. Hu at the beginning of the discussion, the most commonly used drugs in clinical practice are hormonal drugs such as dexamethasone, which use this mechanism of action to induce fetal lung type 2 cells to produce alveolar surfactant.  ps, ultimately avoid white lungs and avoid respiratory distress.

    The current situation is an emergency. The doctor failed to give the mother a lung-stimulating injection in advance. As a result, the baby who was born early had symptoms of respiratory distress. As Dr. Hu said, it was expected by the medical staff.  .

    Since we know that the baby is lacking this substance causing respiratory distress, can we directly give the baby alveolar surfactant?  sure.  The question is, where can such a thing be found in a small health center?

    This medicine is expensive.  Generally, hospitals that do not have a dedicated neonatology department will not have such specialized and expensive drugs.  (Remember the website address: www.hlnovel.com
