The new system offers a better description of underlying pulmonary disease and its severity. [5] "The term 'bronchopulmonary dysplasia' was first used by [William] Northway et al. in 1967 to describe a chronic form of injury to the lungs caused by barotrauma and oxygen injury in preterm infants requiring mechanical ventilation." [6]
The lungs of infants with respiratory distress syndrome are developmentally deficient in a material called surfactant, which helps prevent the collapse of the terminal air spaces (the future site of alveolar development) throughout the normal cycle of inhalation and exhalation. This deficiency of surfactant is related to inhibition from the ...
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.
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. [15]
Bronchomalacia can best be described as a birth defect of the bronchus in the respiratory tract. Congenital malacia of the large airways is one of the few causes of irreversible airways obstruction in children, with symptoms varying from recurrent wheeze and recurrent lower airways infections to severe dyspnea and respiratory insufficiency. It ...
Alveolar capillary dysplasia (ACD) is a rare, congenital diffuse lung disease characterized by abnormal blood vessels in the lungs that cause highly elevated pulmonary blood pressure and an inability to effectively oxygenate and remove carbon dioxide from the blood.
By definition, the episode must have resolved by the time the infant is evaluated by a medical professional. The caregiver may report observation of bluish skin discoloration, called cyanosis. Breathing abnormalities, such as lack of breathing, slow breathing, or irregular breathing may be noted.
Congenital pulmonary airway malformation (CPAM), formerly known as congenital cystic adenomatoid malformation (CCAM), is a congenital disorder of the lung similar to bronchopulmonary sequestration. In CPAM, usually an entire lobe of lung is replaced by a non-working cystic piece of abnormal lung tissue.
