Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress.

Bronchopulmonary dysplasia (BPD; part of the spectrum of chronic lung disease of infancy) is a chronic lung disease which affects premature infants. Premature (preterm) infants who require treatment with supplemental oxygen or require long-term oxygen are at a higher risk. [1]
Infant respiratory distress syndrome (IRDS), also known as surfactant deficiency disorder (SDD), [2] and previously called hyaline membrane disease (HMD), is a syndrome in premature infants caused by developmental insufficiency of pulmonary surfactant production and structural immaturity in the lungs.
The development of the respiratory system begins at about week 4 of gestation. By week 28, enough alveoli have matured that a baby born prematurely at this time can usually breathe on its own. The respiratory system, however, is not fully developed until early childhood, when a full complement of mature alveoli is present.
The lungs are one of the last organs to mature in the womb; because of this, many premature babies spend the first days and weeks of their lives on ventilators. Therefore, a significant overlap exists between preterm birth and prematurity. Generally, preterm babies are premature and term babies are mature.
The lungs may also appear hyperinflated. [5] It is a diagnosis of exclusion as it is a benign condition that can have symptoms and signs similar to more serious syndromes, such as respiratory distress or meconium aspiration. [2] In distinction to transient tachypnea, respiratory distress syndrome is more common in premature infants.
The premature babies, who weigh less than 1.5 kg (3.3 pounds) each and in some cases only 700 or 800 grammes, should be in incubators where the temperature and humidity can be regulated according ...
Prelabor rupture of membranes (PROM), previously known as premature rupture of membranes, is breakage of the amniotic sac before the onset of labour. [2] Women usually experience a painless gush or a steady leakage of fluid from the vagina. [1] Complications in the baby may include premature birth, cord compression, and infection.
