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.
Immediately after delivery, the fundus of the uterus begins to contract. This is to deliver the placenta which can take up to 30 minutes and may involve a feeling of chills. [8] In a normal and healthy response it should feel firm and not boggy. It begins to involute with contractions of the smooth muscle of the uterus. It will contract midline ...
It is seen in many women after delivery and can be unpleasant. It lasts for a short time. It is thought to be a result of a nervous system response. It may also be related to fluid shifts and the actual strenuous work of labor. It is considered a normal response and there is no accompanying fever. A fever would indicate an infection ...
Transient tachypnea of the newborn occurs in approximately 1 in 100 preterm infants and 3.6–5.7 per 1000 term infants. It is most common in infants born by caesarian section without a trial of labor after 35 weeks of gestation. Male infants and infants with an umbilical cord prolapse or perinatal asphyxia are at higher risk
This enables fetal hemoglobin to absorb oxygen from adult hemoglobin in the placenta, where the oxygen pressure is lower than at the lungs. Around 6 months of age after birth, the gamma chains will gradually be replaced by beta chains. This new hemoglobin structure is known as hemoglobin A, composed of two alpha and two beta chains (2α2β). [4]
The condition, which occurs in nearly 15% of births, may begin shortly before or any time after childbirth, but commonly begins between a week and a month after delivery. [ 136 ] Childbirth-related post-traumatic stress disorder is a psychological disorder that can develop in women who have recently given birth.
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.
Clinical manifestations of a subgaleal hemorrhage are variable; it is recommended that the mean time for diagnosis is typically within 1–6 hours after birth, especially if the infant delivery was through vacuum delivery or prolonged due to complications. [22]
