Neonatal sepsis is when bacteria invade the blood, multiply in the blood, produce toxins, and cause systemic infection through blood circulation. Newborns have low disease resistance, and their immunity needs to be gradually improved after birth. Therefore, bacteria can easily enter the body through the skin, digestive tract, and respiratory tract, and sepsis is prone to occur.

There are multiple channels for germs to invade the newborn's body. Before the fetus is born, if the mother is ill or the amniotic fluid is contaminated, the bacteria can invade the fetus through the blood, or the fetus can inhale the contaminated amniotic fluid, causing the bacteria to invade the body. During childbirth, infection can occur due to inadequate disinfection, and bacteria may invade the body through the umbilical cord, skin or oral cavity after birth.

The symptoms of neonatal sepsis are not the same. A small number of sick children have a sudden onset; most sick children only cry or lethargy at first, have fever, eat less milk and are prone to vomiting, deepen jaundice, and abdominal distension. However, almost all sick children have lung damage, alveolar hemorrhage, edema, and shortness of breath and irregularity. Lung injury and hypoxia can be manifested as cyanosis. When a large number of bacteria and their toxins invade the body, it can lead to lower blood pressure, slow blood flow, and a large amount of blood cannot circulate effectively, causing shock. At this time, the main manifestation of the sick child is pale skin and lips. Cyanosis, low heart sounds, fast heart rate, cold sweats, cold limbs, pinkish skin, decreased blood pressure. Because the sick child cannot get sufficient blood flow, the heart, lungs and kidneys and other important organs will be hypoxic, causing late injury, making the child's resistance lower, and more difficult to treat, and severely life-threatening. If germs invade the meninges, symptoms such as convulsions, shortness of breath, and gaze to one side may occur.

The care of newborns is a very important link. If you take good care of it, many infectious diseases can be avoided, at least abnormal phenomena can be discovered in time, and medical treatment can be promptly sought. In order to prevent neonatal sepsis, breastfeeding should be adopted to enhance resistance, and at the same time pay attention to keep warm and add water, and to prevent heatstroke and cool down in summer. Once neonates develop sepsis, they should go to the hospital for treatment as soon as possible.

Neonatal sepsis is an acute infectious disease. Bacteria spread to the body's organs through the bloodstream, causing comprehensive damage to the body. Especially when the lungs are damaged and shock occurs, it will cause hypoxia in the body and aggravate the disease. If not treated in time, it will also lead to hypoxia in other organs, and even life-threatening. Therefore, oxygen therapy should be given to children with neonatal sepsis in time to reduce the damage caused by hypoxia and create conditions for further treatment. One unit Oxygen Concentrator will be helpful. Oxygen is given to newborns at a concentration of 40% to 60%, so as to protect the newborn from hypoxia as much as possible and prevent various irreversible damages.
