My baby is still jaundiced after 24 days.

If the baby continues to show symptoms of jaundice after 24 days, this is not normal. You must take your baby to the hospital in time to receive appropriate treatment measures. Only in this way can you determine whether it is caused by other diseases. After all, there are many types of jaundice nowadays. If you are not careful, the condition will worsen and it will also put a burden on the baby's kidneys.

1. The mucous membrane and skin are light yellow or dark golden yellow, and a few patients experience skin itching.

2. The total bilirubin concentration in the blood increases, and both unconjugated and conjugated bilirubin increase.

3. The bilirubin reaction in urine is positive (conjugated bilirubin is soluble in water and can be excreted from the kidneys).

4. The amount of urobilinogen in urine and sterobilinogen in feces depends on the degree of liver cell damage and capillary bile duct obstruction. If the capillary bile duct is blocked (i.e. bile stagnation in the liver), the content of urobilinogen in urine and sterobilinogen in feces will decrease; when there is no capillary bile duct obstruction, the content of urobilinogen in urine often increases, while the content of sterobilinogen in feces is normal. The reason for the increase in urobilinogen in urine is that urobilinogen is absorbed into the portal vein in the enterohepatic circulation. After liver cells are damaged, their ability to process it into conjugated bilirubin is reduced, so more urobilinogen enters the systemic circulation and causes an increase in urobilinogen in urine.

5. Serological manifestations of impaired liver function, such as significantly increased transaminase and decreased albumin.

6. If the liver damage is caused by viral hepatitis, markers of various types of viral hepatitis will often be positive.

7. Pathological examination of liver biopsy tissue can reveal basic lesions of liver cells.

4. Characteristics of obstructive jaundice

1. The skin is dark yellow, yellow-green or green-brown, often accompanied by skin itching, and a few patients have bradycardia.

2. The urine is dark in color, like strong tea, and the stool becomes lighter in color. When the extrahepatic bile duct is completely blocked, the stool becomes white clay in color.

3. The total serum bilirubin increases, mainly the conjugated bilirubin.

4. Decreased or absent urobilinogen in urine.

5. Bilirubin in urine is positive.

7. Serum alkaline phosphatase, γ-glutamyl transpeptidase and total cholesterol are increased, and lipoprotein-X is positive.

9. Liver biopsy and laparoscopy: They are of great help in the diagnosis of difficult cases of jaundice. However, when liver biopsy is used for cholestatic jaundice, bile overflow may occur, causing peritonitis. Patients with poor liver function may also suffer from internal bleeding due to coagulation disorder. Therefore, the indications should be carefully considered.
