A child has a high fever: when to call for help and when to call a doctor

Other names: Высокая температура у ребёнка, жар у ребёнка, температура 39 у ребёнка, лихорадка у детей, чем сбить температуру ребёнку, температура без симптомов у ребёнка, белая лихорадка

An increase in temperature in a child is not a disease, but a protective reaction of the body to infection. In most cases, the cause is viruses, and the fever lasts for several days, after which it goes away on its own. Danger is determined not by the number on the thermometer, but by how the child looks and behaves: an active baby with a temperature of 39 °C is usually less anxious than a lethargic child with 38 °C. The task of parents is not to “knock down at any cost,” but to make them feel better, provide drinking water, and notice in time the signs that require a doctor or an ambulance.

Why is temperature needed?

A rise in temperature speeds up the immune system and makes it difficult for many germs to multiply, so a moderate fever is beneficial. By itself, it does not damage the brain and does not “burn” the body, as is commonly believed. The danger comes from the illness that caused the fever and from dehydration, not from the numbers. Therefore, the goal of treatment is not to achieve 36.6 °C, but to make the child feel better: drink, sleep and play. Reducing the temperature by a degree to one and a half is usually sufficient.

Fever is a protective reaction, not a disease
High fever itself does not damage the brain
The goal is to improve well-being, not normalize the number
The main risks are underlying illness and dehydration.
Assess behavior, breathing, drinking and urination

When to lower the temperature

They focus primarily on well-being. If a child drinks, plays and is calm at 38.5 °C, an antipyretic may not be given. If he is suffering, he has chills, headache, he refuses to drink - the drug is appropriate even at lower numbers. Children with chronic diseases of the heart, lungs and nervous system, as well as children who have previously had febrile convulsions, require special attention: for them the doctor gives individual recommendations. The drug, dose and frequency are determined by the pediatrician based on age and weight.

The main guideline is the child’s well-being
If poorly tolerated, reduce at 38 °C
If you are feeling well and drinking, you can observe
A special approach for chronic diseases
The dose is calculated by weight, not by age, by eye
Do not give medications “on schedule” unless necessary
Do not use acetylsalicylic acid preparations in children

What not to do

Rubbing with vodka, alcohol and vinegar is dangerous: these substances are absorbed through the child’s skin and can cause poisoning. Cold wraps and ice baths provoke shivering, which causes the temperature to rise even more. You should not wrap your child in blankets when it’s hot and, conversely, strip him naked when he’s chilly. Antibiotics do not reduce fever during a viral infection and are prescribed only by a doctor. You cannot combine several antipyretics or exceed the frequency of administration in the hope of a quick effect.

Do not wipe with alcohol, vodka, vinegar
Do not give cold baths or wraps
Do not bundle up when it’s hot and don’t overcool when you have chills.
Do not give antibiotics without a doctor's prescription
Do not exceed the dose and frequency of antipyretics
Do not give acetylsalicylic acid preparations
Don't give up drinking in favor of taking medications

How to care for a child

The main thing is to drink regularly: water, compote, fruit juice, saline solutions, and for infants - more frequent breastfeeding. With fever, fluid loss increases, and dehydration is more dangerous than the temperature itself. The room is maintained with cool, fresh air and the child is easily dressed. There is no need to force feed: your appetite will return after recovery. Bed rest is not necessary if the child wants to play. It is useful to record when and what you gave, how the temperature changed, and how many times the child urinated.

Drink small amounts frequently
More frequent breastfeeding in babies
Cool ventilated air in the room
Light clothing without wrapping
Don't force him to eat
Quiet games and relaxation at the request of the child
Diary of temperature, drinking and urination

When are tests and a doctor needed?

A pediatrician's examination is always necessary if the child is less than three months old, if the temperature lasts longer than three days without an obvious source, and also if there is any deterioration. The doctor looks for the source of infection: throat, ears, lungs, urinary tract. If the lesion is not found, a complete blood and urine test and C-reactive protein are prescribed, because in young children a urinary tract infection often occurs only with fever. A chest x-ray is done if pneumonia is suspected. An antibiotic is prescribed only for a confirmed bacterial infection.

Same day examination for children under 3 months
Visit your doctor if you have a fever longer than three days
General analysis of blood and urine for fever without a focus
C-reactive protein
Chest X-ray for suspected pneumonia
Re-inspection when temperature returns
Antibiotic only for proven bacterial infection

Frequently asked questions: High temperature in a child

At what temperature should an antipyretic be given?+

There is no universal number. They focus on their well-being: if a child plays and drinks at 38.5 °C, you can wait, but if he suffers at 38.0 °C, give the drug. The dose by weight and the drug is determined by the pediatrician, especially for children of the first year.

Is it possible to wipe a child with vinegar or vodka?+

No. These substances are absorbed through the skin and can cause poisoning in a child. It is safer to undress to light clothing, ventilate the room and offer drink. Wiping with water at room temperature is acceptable if the child enjoys it.

How many days can a fever last for ARVI?+

Usually 3–5 days. If the fever persists longer, rises again after improvement, or new symptoms appear, you need to be re-examined by a doctor to rule out complications such as otitis media or pneumonia.

Are febrile seizures dangerous?+

They are scary, but most often short-lived and do not damage the brain. The child needs to be placed on his side, dangerous objects removed, nothing put in his mouth, and the time noted. After the first attack in your life, a doctor’s examination is required; in case of prolonged convulsions, call 103.

Do you need an antibiotic at a temperature of 39?+

A high temperature in itself is not an indication for antibiotics: most fevers in children are caused by viruses. An antibiotic is prescribed by a doctor for a confirmed bacterial infection, such as ear infection, pneumonia, or a urinary tract infection.
