What should I do if I have a persistent high fever that won't go away?
Generally, high fever refers to elevated body temperature. For persistent high fever that does not subside, methods such as cold compresses, tepid sponging, fluid supplementation, oral medications, and intravenous therapy can be used to reduce fever. Specific approaches are analyzed as follows:
1. Cold Compress
Patients with high fever may apply cold wet towels to the forehead, wrists, and lower legs. Cold compresses assist in heat dissipation and can rapidly lower localized body temperature, thereby alleviating patient discomfort.
2. Tepid Sponging
Tepid sponging is an effective physical cooling method for patients with high fever. It involves wiping not only the hands and feet but also the trunk. As the water evaporates from the skin, it carries away some body heat, helping to lower body temperature. Additionally, tepid sponging promotes dilation of cutaneous capillaries, facilitating heat release.
3. Fluid Supplementation
Adequate fluid intake is essential during fever to replace lost bodily fluids, prevent dehydration, and support metabolic processes that aid in heat dissipation. Increased fluid intake also boosts urine output, which helps eliminate toxins, viruses, and bacteria from the body.
4. Oral Medications
Antipyretic drugs are generally recommended when body temperature exceeds 38.5°C. Commonly used antipyretics include acetaminophen tablets, ibuprofen sustained-release capsules, and diclofenac sodium sustained-release capsules, which are relatively safe and have fewer side effects. Ibuprofen suspension is commonly used for infants and children.
5. Intravenous Therapy
If persistent high fever fails to improve despite physical cooling measures and antipyretic medications, treatment under medical supervision with intravenous agents such as dexamethasone sodium phosphate injection or hydrocortisone injection may be recommended.
If a patient experiences persistent high fever unresponsive to initial treatments, prompt medical evaluation is advised. Comprehensive examinations should be conducted under the guidance of a qualified physician to determine the underlying cause and initiate targeted treatment, avoiding delays in care.
