Patient discussion about hyalinization

Q. HYALINE MEMBRANE DISEASE in pre-mature infants;what are the causes of it in pregnant women?

A. the cause of Hyaline Membrane disease is pre-mature birth. while the fetus develop, about in the 29th week a substance called surfactant is created in the lungs. this substance's function is to change the surface tension of the fluid in the lungs- therefore decreasing it's force. the surface tension tends to shrink the lungs and can cause the lungs to collapse. so a premature baby wouldn't be able to breath properly.
