What should I do if my newborn creatine kinase isoenzyme 205 falls instead of rising?

Firstly, creatine kinase isoenzyme (CK-MB) is a marker of myocardial injury, which is usually used to diagnose myocardial infarction and other diseases. After the newborn is born, due to physiological factors, the level of CK-MB will naturally decline, but the speed of decline varies from person to person. Generally speaking, the level of CK-MB will gradually increase in the first few days after birth, and then gradually decrease after reaching the peak. According to the information you provided, the CK-MB level dropped from more than 400 to 2 10 within/2 days after the child was born, indicating that the decline rate was relatively fast.

However, after discharge 10 days, CK- methyl bromide level remained at 205, and did not continue to decrease. This may mean that the child's myocardial injury has not fully recovered, or there are other diseases or conditions that lead to the increase of CK-MB level. In this case, it is recommended that you consult a doctor to further evaluate your child's health.

Besides, you mentioned that the baby is almost full moon, but BCG and hepatitis B vaccine have not been given yet. BCG and hepatitis B vaccine are one of the necessary vaccines for newborns to prevent tuberculosis and hepatitis B. If your child has not been vaccinated, it is recommended that you consult a doctor as soon as possible to arrange vaccination.
