Doba trvání křeče u dětí: kdy je to normální a kdy jít k lékaři

When a child has a seizure, it’s one of the most terrifying things a parent can witness. křeče u dětí, nekontrolované svalové kontrakce způsobené náhlou elektrickou aktivitou v mozku. Also known as horečkové křeče, they most often happen when a child’s temperature rises quickly, usually in the first 24 hours of an infection. Most of these seizures last less than five minutes — and while they look scary, they rarely cause lasting harm. But knowing how long is normal and when to act can make all the difference.

Typical horečkové křeče, benigní křeče spojené s náhlým vzestupem teploty u zdravých dětí mezi 6 měsíci a 5 lety usually stop on their own within 1 to 3 minutes. The child might stiffen, shake, roll their eyes, or even lose consciousness. Afterward, they’re often sleepy or confused for a short while — and that’s okay. What’s not okay is if the seizure lasts longer than five minutes, repeats within 24 hours, or affects only one side of the body. In those cases, you need emergency help. dětské křeče, nejen horečkové, ale i ty, které vznikají bez teploty, mohou být příznakem jiného problému — like a brain infection, metabolic disorder, or epilepsy. That’s why every first seizure, even if short, should be checked by a doctor.

You won’t always see a fever before the seizure — sometimes the temperature spikes right as the child starts convulsing. That’s why measuring temperature during or right after a seizure matters. Don’t wait to see if it gets worse. If your child has a seizure for the first time, call emergency services or go to the nearest hospital. After that, follow up with your pediatrician. They’ll ask about the duration, what the child was doing before, whether there was a fever, and if there’s a family history. These details help rule out serious causes.

Most kids who have a single febrile seizure won’t have another. But if your child has had one before, you’re more likely to see a second one — especially if they’re under 18 months or if the fever rises very fast. That’s why it’s smart to have fever-reducing medicine ready at home, and to know how to use it correctly. But remember: medicine doesn’t prevent seizures, it only helps manage the fever. The seizure itself is the body’s reaction to the spike, not the fever alone.

There’s no magic trick to stop a seizure once it starts. Don’t put anything in the child’s mouth. Don’t try to hold them down. Just keep them safe — lay them on their side, clear the area, and time it. After it ends, comfort them and monitor their breathing. If they’re breathing normally and wake up, you still need to get them checked. Not because the seizure was dangerous, but because it’s a signal — something in their body is out of balance.

The collection below gives you real-life guidance from parents and pediatricians on what to do before, during, and after a seizure. You’ll find answers about when to call an ambulance, how to tell if it’s just a fever seizure or something more, what tests doctors might order, and how to reduce the risk of recurrence. We also cover what to expect after a seizure — from sleepiness to confusion — and why it’s not something to panic about, but also not something to ignore.
