Febrile convulsion pathophysiology

Fever changes the body's internal environment, and a young child's brain is still maturing. In some children, this combination lowers the threshold for coordinated electrical activity to become temporarily disorganised. The result can be stiffening, rhythmic jerking, reduced awareness, or a brief period of unresponsiveness. The seizure is linked with the fever, not necessarily with the highest temperature reached. The infection causing the fever must still be considered, because meningitis and other illnesses require different care.

Protect the child from nearby hazards, place them on their side when feasible, and record the start and finish time. Keep the airway clear without putting fingers or objects in the mouth. Do not restrain the body or give liquids during the event. Once the child is awake, follow the clinician's advice for fever care and arrange assessment of the illness that caused it.

Call emergency services if the seizure continues beyond five minutes, repeats, causes breathing difficulty, or leaves the child difficult to wake. Seek urgent assessment for a stiff neck, unusual rash, severe headache, persistent vomiting, or marked deterioration. These findings can point to a serious infection rather than an uncomplicated febrile event.

Ask how the seizure pattern fits a fever-related event, what examination is needed, how recurrence should be handled, and how to distinguish warning signs of meningitis or hypoglycaemia.
