After chemotherapy for children, routine blood tests may reveal a decrease in white blood cells, hemoglobin, and platelets, which is commonly referred to as a “drop in blood count”. This is because most chemotherapy drugs have a mild or severe myelosuppressive effect. In today’s topic, I would like to tell parents what they should pay attention to when their children lose blood after chemotherapy. What chemotherapy drugs can cause blood loss? Most chemotherapy drugs can cause varying degrees of blood loss. Chemotherapeutic drugs that may have a strong effect on bone marrow suppression include: cytarabine, desoxorubicin (trade name: Enonin or Sunvita), and hypertrigonelline. If multiple drugs are used in combination, the blood loss may be more severe. What should I pay attention to in my diet during bleeding? Avoid eating cold dishes; try to eat the same meal, not overnight food. Fruits in season, local fresh fruit is preferred, do not eat fruits in the opposite season. If your child has a low white blood cell count after chemotherapy, it is best to steam the fruit before eating it. How to read the routine blood test? Of course, the safest way is to seek out the supervising physician and have them help you look at your child’s labs and guide the next course of treatment. Don’t be nervous and panic when your child’s platelets drop, check out another article I wrote – What to do when your child’s platelets drop after chemotherapy? Is it okay to stay home during the drop? Since the beds in our department are very tight, generally speaking, children usually stay at home during the early stage of blood loss because the drop in white blood cells and platelets is not very strong. Staying at home makes the child feel good and rest better, avoids cross-infection that often occurs in hospitals, and makes it easier for parents to cook for the child. The downside is that it is not convenient for the medical staff to observe the child’s condition. You can read my previous article on the “five hurdles” that must be overcome during the first hospitalization of a first-time patient because of the same infection and bleeding hurdles during the hemorrhage. When do I have to go back to the hospital? If your child has a fever (temperature greater than 37.4°C), or if your child shows signs of infection (e.g. cough, abdominal pain, diarrhea, perianal pain, etc.), or if he/she shows signs of bleeding such as nosebleeds, or if your child is not well, please return to the hospital promptly. Finally, I would like to tell all parents of affected children: Be sure to build up the confidence that you can take care of your child! Take good care of your child during the period when the child is dropping blood after chemotherapy, and assist the medical staff to win this battle!
