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.
Aspiration is defined as inhalation of oropharyngeal or gastric contents into the pulmonary tree. Depending on the composition of the aspirate, three complications have been described: [ 4 ] Chemical pneumonitis may develop whose severity depends on the pH value and quantity of aspirate. [ 4 ]
Oral ingestion of hydrocarbons often is associated with symptoms of mucous membrane irritation, vomiting, and central nervous system depression. Cyanosis , tachycardia , and tachypnea may appear as a result of aspiration, with subsequent development of chemical pneumonitis.
Meconium aspiration syndrome (MAS), also known as neonatal aspiration of meconium, is a medical condition affecting newborn infants. It describes the spectrum of disorders and pathophysiology of newborns born in meconium-stained amniotic fluid (MSAF) and have meconium within their lungs. Therefore, MAS has a wide range of severity depending on ...
An exogenous preparation of pulmonary surfactant, either synthetic or extracted from animal lungs, is given through the breathing tube into the lungs. Surfactant medications can decrease the risk of death for very low-birth-weight infants who are hospitalized by 30%. [28] Such small premature infants may remain ventilated for months.
An abrupt stop of pulmonary gas exchange lasting for more than five minutes may permanently damage vital organs, especially the brain. Lack of oxygen to the brain causes loss of consciousness. Brain injury is likely if respiratory arrest goes untreated for more than three minutes, and death is almost certain if more than five minutes.
Common symptoms of LPR in infants include wheezing, stridor, persistent or recurrent cough, apnea, feeding difficulties, aspiration, regurgitation, and failure to thrive. [14] Moreover, LPR in children is commonly concomitant with laryngeal disorders such as laryngomalacia, subglottic stenosis, and laryngeal papillomatosis. [4]
