If a 10-month-old baby has a fever with a temperature of 39℃, it is a high fever. A high fever state may cause febrile convulsions in children due to high fever, which is a dangerous symptom. High fever convulsions leading to convulsions may cause complications such as tongue bite, so it is more dangerous when high fever. However, if the child is actively given symptomatic medication according to the temperature, it is not dangerous and can be treated immediately with oral antipyretic medication at this temperature, such as oral acetaminophen or ibuprofen. However, if the child’s hands and feet are cold after taking oral medication, or if the child’s temperature does not drop significantly within 1-2 hours after taking oral medication, the child should be taken to the hospital for antipyretic treatment as soon as possible, and the actual cause of the child’s illness should be identified for further symptomatic medication.
