When the baby is born, the lungs are needed for oxygen transfer and need high blood flow which is encouraged by low PVR. The failure of the circulatory system of the newborn to adapt to these changes by lowering PVR leads to persistent fetal circulation. [2] The newborn is therefore born with elevated PVR, which leads to pulmonary hypertension.
Regions with low neonatal mortality include Europe, the Western Pacific, and the Americas, which have sepsis rates that account for 9.1% to 15.3% of the total neonatal deaths worldwide. This is in contrast with the 22.5 to 27.2% percentage of total deaths in resource-poor countries such as Nigeria, the Democratic Republic of the Congo, India ...
Basically, understanding of the etiology of perinatal asphyxia provides the platform on which to build on its pathophysiology. The general principles guiding the causes and the pathophysiology of perinatal asphyxia are grouped into antepartum causes and intra partum causes. As these are the various points to which insults can occur to the foetus.
The causes of neonatal hepatitis are many. Viruses that have been identified include cytomegalovirus, rubella virus, hepatitis A and B viruses, herpes simplex viruses, coxsackievirus, echovirus, and paramyxovirus. [2]
As the disease progresses, the baby may develop ventilatory failure (rising carbon dioxide concentrations in the blood) and prolonged cessations of breathing ("apnea"). Whether treated or not, the clinical course for the acute disease lasts about two to three days. During the first day, the child worsens and requires more support.
Newborn infant with Rhesus disease, a type of hemolytic disease of the newborn, suffering from hydrops fetalis. The infant did not survive. [4] Hydrops fetalis usually stems from fetal anemia, when the heart needs to pump a much greater volume of blood to deliver the same amount of oxygen. This anemia can have either an immune or non-immune cause.
A newborn baby who was discovered atop a trash can on Chicago's Northwest Side is now hospitalized in critical condition, the Associated Press reports.. A passerby found the infant boy and carried ...
Neonatal stroke, similar to a stroke which occurs in adults, is defined as a disturbance to the blood supply of the developing brain in the first 28 days of life. [1] This description includes both ischemic events, which results from a blockage of vessels, and hypoxic events, which results from a lack of oxygen to the brain tissue, as well as some combination of the two.
