Perinatal asphyxia happens in 2 to 10 per 1000 newborns that are born at term, and more for those that are born prematurely. [1] WHO estimates that 4 million neonatal deaths occur yearly due to birth asphyxia, representing 38% of deaths of children under 5 years of age.
Intrauterine hypoxia can be attributed to maternal, placental, or fetal conditions. [12] Kingdom and Kaufmann classifies three categories for the origin of fetal hypoxia: 1) pre-placental (both mother and fetus are hypoxic), 2) utero-placental (mother is normal but placenta and fetus is hypoxic), 3) post-placental (only fetus is hypoxic).
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.
An early stage of hyperthermia can be "heat exhaustion" (or "heat prostration" or "heat stress"), whose symptoms can include heavy sweating, rapid breathing and a fast, weak pulse. If the condition progresses to heat stroke, then hot, dry skin is typical [ 2 ] as blood vessels dilate in an attempt to increase heat loss.
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.
Early-onset sepsis (EOS), defined as onset of symptoms within 72 hours of life, is generally caused by transmission of pathogens from the female genitourinary system to the fetus. Pathogens can infect the fetus via vertical transmission (direct transmission through the placenta in utero) or infection during delivery as fetus passes through ...
An Illinois mom was arrested after her 1-month-old son died from “severe” hyperthermia and dehydration — after the newborn was abandoned in a hot car for an “extended period,” according ...
Signs and symptoms of pregnancy are common, benign conditions that result from the changes to the body that occur during pregnancy. Signs and symptoms of pregnancy typically change as pregnancy progresses, although several symptoms may be present throughout. Depending on severity, common symptoms in pregnancy can develop into complications. [1]
