How Alert is Your Neonatal Baby? Your newborn baby is likely to be alert for the first hour after birth if the mother has breastfed. If the mother had used pain medication during labor, she may be alert in the early hours after birth. Regardless, breastfeeding helps trigger the involution process of the uterus and stimulate the release of oxytocin, a hormone that helps the uterus to contract. Most neonates are alert during the first hour after birth, although they may seem groggy or unresponsive if they've had pain medication administered late in the labor.Ductus arteriosusThe ductus arteriosus is a small blood vessel located between the pulmonary artery and aorta. This opening diverts blood away from the developing lungs, where it receives oxygen from the mother's circulation. The ductus usually closes within two to three days after birth, but in some premature infants, this closure may be delayed or absent altogether. In such cases, blood flow through the ductus arteriosus can become too large and can result in pulmonary hypertension and heart problems.Lung surfactantNeonatal respiratory distress syndrome is a serious condition that results from a lack of lung surfactant in newborns. The development of this vital system in the newborn is influenced by a wide range of environmental factors. These factors include the presence of maternal circulation, which carries agents and chemicals from the mother's uterus to the placenta. These early insults may persist in the infant's lung development, even after birth. The surfactant system is also sensitive to oxygenation changes and exposure to pollutants.Neonatal kidneyThe neonatal kidney is an extremely immature organ, exhibiting reduced glomerular filtration, active tubular secretion, and renal blood flow. These factors depend on gestational and postnatal ages, and many neonatal pathological conditions can affect the renal function. The developmental changes that occur in the fetal kidney can have a profound impact on drug metabolism and toxicity. Therefore, it is important to identify and treat conditions that affect the neonatal kidney to prevent toxicity and maximize the benefits of drugs.Blood-brain barrierThe blood-brain barrier is a network of closely-spaced cells and vessels that prevents certain harmful substances from entering the brain. Some substances can pass through, however, such as water, oxygen, carbon dioxide, and general anesthetics. Anticancer drugs, meanwhile, cannot pass through the blood-brain barrier. However, there are several potential pathways for S. pneumoniae to enter the brain.SleepThe majority of human neonates spend the vast majority of their time sleeping. This period is crucial for learning, as newborns are rapidly developing their sense of self and environment. Although neonates' sleep patterns differ from adult sleep, there are some unique characteristics of newborn sleep that appear to contribute to learning. For example, sleep facilitates neural maturation and plays an important role in memory consolidation of material presented while the infant was awake. Moreover, emerging evidence suggests that infants process sensory stimuli and learn about contingencies in their environment during sleep.PreeclampsiaThis condition affects infants born to mothers who have had preeclampsia. The risks of a Neonate being born with preeclampsia include multiple gestation, preterm delivery, and cesarean section. Additionally, neonates born to preeclamptic mothers are at a higher risk of thrombocytopenia and hypoglycemia. Additionally, preeclamptic infants may experience developmental delays or behavioral problems later in life. A long-term follow-up is necessary for assessment of neurological and behavioral consequences.Signs of an injury in a neonateNeonatal spinal cord injury is a relatively uncommon complication of delivery trauma. Typical symptoms include decreased movement, loss of reflexes, respiratory insufficiency, and limb weakness. In one case, a neonate who sustained a cervical shunt injury presented with hoarseness and choking milk at feeding. Because the signs and symptoms were subtle, the neonate did not receive immediate medical attention. However, the child was successfully treated after a period of corticosteroid therapy and rehabilitation. Nonetheless, the neonate still required ventilator support at night.
