Newborns have a high incidence of the disease because their organs are not yet mature and their immune function is relatively poor. Symptoms of the disease are not typical enough to be easily detected. However, if you can observe carefully, you can still find the problem. Neonatal diseases in general seem to have the following three aspects of the performance. First, the systemic symptoms of the newborn’s various diseases, can appear systemic symptoms, the more prominent is the “three not”: 1, do not eat, that is, refused to eat the milk, barely eat easily vomit. 2, do not sound, normal newborns, the newborn’s symptoms are not typical, so it is not easy to find the problem. 2, not loud, normal newborns cry loud and clear, when the disease is serious, the sound is weak or not instrument, sleep time is longer than normal newborns. 3, weight does not increase or decrease. However, some newborns do not show the “three noes” after getting sick, but on the contrary, they are irritable and restless, crying and fussing, and refusing to fall asleep. Infectious diseases in other ages often manifested as fever, but the newborn infections are not necessarily fever, body temperature can be normal, when the disease is serious, the body temperature can not be high, or even cold. Second, the special performance of each system diseases, for example, when the whistle system diseases have nasal congestion and cough, the newborn nasal congestion affects the whistle and suckling, so often crying and restlessness when breastfeeding. Shortness of breath or foaming at the mouth when the newborn suffers from pneumonia. Vomiting, diarrhea, bloating or constipation in digestive disorders. In central nervous system diseases (such as purulent meningitis), there are fixed eyes and twitching of muscles in various parts of the body. Changes in color of face and skin The skin of normal newborns is delicate and light red, and the lips and mouth are dark red. When the disease may appear: 1, jaundice, although normal newborns in the postnatal 3-10 days can appear physiological jaundice, but this jaundice color is not deep, and does not affect the child’s appetite and mental state, if the jaundice is deeper, or suddenly aggravated, or more than 10 days after the birth of the child is still persistent, may be a manifestation of the disease, need to be consulted. 2, mucous membranes (such as lips and mouth), perioral lips or fingernails are blue-gray, often due to low arterial blood oxygen concentration or due to slow blood flow in shock, most often seen in sepsis and sclerosis and other serious diseases, often accompanied by atrophy, poor appetite and other symptoms. Simple mucous membrane and skin cyanosis is mostly cyanotic congenital heart disease. 3. Measles-like rash may appear on the skin in certain viral infectious diseases, distributed on the forehead, abdomen, back and face. 4, severe sepsis or hemorrhagic disease when the limbs, chest and neck or other parts of the skin may appear deep red bleeding spots or purple-red ecchymosis. 5. Pale skin and mucous membranes indicate anemia, mostly caused by hemolytic or bleeding disorders. In addition, edema or sclerosis of the skin and subcutaneous tissue is also a manifestation of the disease. Various congenital malformations and hereditary diseases, although already present at birth, do not all develop in the neonatal period. For example, there are many types of congenital heart disease, but the ones that develop in the neonatal period are mainly complex malformations such as malposition of the large blood vessels, hypoplasia of the left heart, and abnormalities of pulmonary venous return. Digestive tract malformations in the neonatal period onset of more, such as esophageal obstruction, pyloric hypertrophy, small intestinal dysplasia food stores, anus, etc., these diseases have the special symptoms of each system, it is not difficult for parents to find. In short, the newborn disease type cool, the symptoms are not typical, but such as weekdays parents pay more attention to the child’s eating, sleeping, crying, urination and defecation, whistle and other living conditions, breastfeeding, changing diapers and bathing and changing clothes pay attention to whether there are special signs, it is not difficult to early detection of disease.
