The principles of first aid for febrile convulsions are as follows: First, the airway should be opened quickly so that the patient can be fully oxygenated to avoid asphyxia and respiratory failure caused by respiratory upset due to convulsions, and the balloon mask oxygen or shielded oxygen inhalation method can be given immediately. Second, the obstruction of the digestive system should be quickly lifted in the case of febrile convulsions, because there is usually nausea and vomiting before coma, at which time the respiratory tract should be quickly cleaned and the foreign body in the mouth removed or the vomit discharged. Third, to avoid tongue drop and cause asphyxiation during convulsions, the patient should be given a tongue depressor to avoid a transient tongue bite and tongue drop during convulsions due to convulsions. Fourth, sedative treatment should be given quickly, and rapid physical cooling and antipyretic treatment should be given. Fifth, immediately give the method of monitoring the electrocardiogram, blood pressure, heart rate, oxygen saturation, pulse and other methods, and closely observe the changes in the condition.
