After being irradiated by this light, bilirubin is oxidized to colorless substance and excreted from urine and bile.
This treatment is simple and effective.
Put baby in incubator, remove clothes and diapers, cover eyes with black eye mask (gauze wrapped with black paper).
The light source was placed 33-35cm away from the body surface, and the body position was changed every hour to increase the light area.
The illumination time is mostly 24-48 hours, and the longest is 96 hours.
During the treatment, we should pay attention to liquid supply (to prevent dehydration) and liver protection treatment.
After this treatment, jaundice subsided and serum bilirubin decreased rapidly.
If the serum indirect bilirubin is more than 20 mg/dl (342 μ mol/L), exchange transfusion is needed.
In order to avoid aggravation and jaundice after blood transfusion, blood donors should first perform screening test for G6PD deficiency.
Avoid blood supply from relatives.
If jaundice is not serious, no blood transfusion is needed.
2. The cause of neonatal hemolytic jaundice is excessive bilirubin production. The serum unconjugated bilirubin is increased due to the destruction of excessive red blood cells and the increase of intestinal and hepatic circulation.
The common causes are: polycythemia, extravascular hemolysis, homologous immune hemolysis, infection, increased intestinal and liver circulation, red blood cell enzyme deficiency, abnormal red blood cell morphology, hemoglobinopathy, vitamin E deficiency and hypozincemia.
The disorder of liver bilirubin metabolism results in the increase of unconjugated bilirubin in serum due to the low function of hepatocyte uptake and conjugated bilirubin.
The common causes are: hypoxia and infection, crigler Najjar syndrome (congenital uridine diphosphate glucuronosyltransferase deficiency), Gilbert syndrome (congenital non hemolytic unconjugated bilirubin increase), Lucey Driscoll syndrome (familial temporary neonatal jaundice), drugs (such as sulfanilamide, salicylate, indomethacin, lanolin C), congenital hypothyroidism Hypopituitarism, trisomy 21 syndrome, etc.
3. The serious complication of neonatal jaundice is bilirubin encephalopathy.
The unconjugated bilirubin can enter the brain through the blood-brain barrier and cause bilirubin encephalopathy when the serum bilirubin is seriously increased or there are high-risk factors at the same time.
Most of them were found within 1 week after birth, and the earliest symptom of nervous system appeared in 1-2 days after birth.
Hemolytic jaundice appeared earlier, mostly occurred in 3-5 days after birth.
Premature infants or other causes are mostly found in 6-10 days after birth.
When there are high risk factors such as premature delivery, asphyxia, dyspnea or hypoxia, severe infection, hypoalbuminemia, hypoglycemia, hypothermia, acidosis or body weight lower than 1.5kg, bilirubin encephalopathy may occur when serum bilirubin is lower than the critical value.
Symptoms usually appear in 12-48 hours after the peak of severe jaundice.
Neonatal jaundice how to care for 1, judge the degree of jaundice.
Parents can observe the degree of jaundice of newborn skin under natural light. If it is only facial jaundice, it is mild jaundice; if the skin of trunk is yellow, it is moderate jaundice; if the limbs and hands and feet are also yellow, it is severe jaundice.
2. Observe stool color.
If the stool is clay colored, pathological jaundice should be considered, which is mostly caused by congenital biliary malformation.
If the degree of jaundice is severe, accompanied by symptoms or abnormal stool color, timely go to the hospital to avoid delay in treatment.
3. Let the fetus out as soon as possible.
Because fetal feces contain a lot of bilirubin, if the fetus is not discharged clean, bilirubin will be absorbed into the blood through the special liver and intestinal circulation of the newborn, so that jaundice increases.
4. To the newborn adequate water, urine too little is not conducive to the excretion of bilirubin.
5. During the period of jaundice, we should give enough sugar water and heat, and protect the liver.
The harm of neonatal jaundice the physiological jaundice of newborn can subside by itself, but pathological jaundice is a group of diseases composed of many reasons, which must be found and treated as soon as possible.
Neonates with severe jaundice should be alert to the occurrence of nuclear jaundice, especially the immature infants. The higher the incidence of the disease, the higher the incidence of the disease. The incidence rate of mental malaise, lethargy, sucking milk weakness, muscle tension reduction, vomiting and no feeding can be seen within 12-48 hours after the occurrence of severe jaundice.
Pathological jaundice can cause "nuclear jaundice" no matter what the cause is. Its prognosis is poor. In addition to nervous system damage, serious jaundice can cause death.
Therefore, the prevention of neonatal pathological jaundice should be focused on, such as prevention of Toxoplasma and rubella virus infection during pregnancy, especially in the early pregnancy; prevention of septicemia after birth; hepatitis B vaccination at birth.
