Patient's question:
Main symptoms: Afebrile convulsionsOnset time: After receiving the triple vaccine booster on the 6th, the child was in good spirits. At around 8:00 PM, sudden multiple afebrile convulsions occurred. Initially, the child became completely limp and weak, followed by eyes rolling upward and a pale, bluish complexion. It took 2-3 minutes of pinching the philtrum to regain consciousness. Subsequently, the temperature began to rise to 38.2°C. Blood tests showed no abnormalities, and the child was given ibuprofen at the hospital to bring down the fever. The next day, everything returned to normal.
On the 15th, with symptoms of indigestion and diarrhea, the child received the meningococcal vaccine. Three days later in the morning, the temperature was 37.6°C, and after taking fever-reducing medication, it returned to normal. The child was in good spirits. In the afternoon, after drinking a pack of Heshengyuan (a probiotic supplement) one hour later, sudden afebrile convulsions occurred again. Initially, the child became completely
Doctor's answer:
According to the condition of your baby as described, the following suggestions are provided:1. The baby is young, and the development of the nervous system is not yet fully mature. Any slight carelessness (such as fever, especially high fever) can easily lead to symptoms like convulsions. This is determined by the physiological and pathological characteristics of children.
2. Based on your description, I personally consider that your baby's frequent convulsions may be related to their constitution, particularly epilepsy susceptibility. Are there any cases of epilepsy in close relatives? After receiving the DTP and meningococcal vaccines, the baby experienced seizures. It is highly likely that your baby has an inherent epilepsy susceptibility, and both vaccines may have triggered or worsened epilepsy. The seizures were likely induced by the vaccination.
3. Currently, even without fever, the baby is experiencing convulsions, looking up with both eyes, and feeling weak all over after the episode—classic symptoms of epilepsy. This warrants consideration of an epilepsy diagnosis. Although you have conducted an electroencephalogram (EEG) and found no abnormalities, a single normal result cannot rule out epilepsy. This is because EEG abnormalities only occur during epilepsy attacks when symptoms are present. Clinically, such cases exist. Therefore, it is recommended to conduct multiple EEGs, especially when symptoms occur, though this can be difficult to determine. I suggest you observe the baby more carefully and monitor their condition closely.
4. In both instances, the baby developed symptoms after taking Shengyuan (a probiotic supplement). Is there a correlation between the two? This needs to be considered. Could it be that certain trace elements or ingredients in the supplement are sensitive to the baby? I recommend closely monitoring the situation. If this occurs again, it would be advisable to stop using the supplement.
