Manifestations: When the newborn cries, there is a reversal of blood flow through the foramen ovale which causes the newborn to appear mildly cyanotic in the first few days of life. The heart rate of the newborn should be between 110 and 160 beats per minute and it is common for the heart rate to be irregular in the first few hours following birth.
Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates.
In humans, the circulatory system is different before and after birth. The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels. A major difference between the fetal circulation and postnatal circulation is that the lungs are not used during the fetal stage ...
Vitamin K deficiency bleeding (VKDB) of the newborn, previously known as haemorrhagic disease of the newborn, [1] is a rare form of bleeding disorder that affects newborns and young infants due to low stores of vitamin K at birth. [2] It commonly presents with intracranial haemorrhage with the risk of brain damage or death. [3]
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.
It will contract midline with the umbilicus. It begins its contractions and by twelve hours after the birth it can be felt to be at the level of the umbilicus. [9] The uterus changes in size from one kilogram to 60-80 grams in the space of six weeks. After birth, the fundus contracts downward into the pelvis one centimeter each day.
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.
Newborn baby immediately after birth, covered in vernix Vernix caseosa , also known as vernix , is the waxy gray substance found that consumes the skin of newborn human babies . [ 1 ] It is produced by dedicated cells and is thought to have some protective roles during fetal development and for a few hours after birth.
