What Do Hospitals Do for High Fevers?

A high body temperature, or fever, indicates the body’s immune response to an infection or illness. While a fever is a symptom, its elevation can signal a serious underlying condition requiring medical attention. For adults, a temperature of 103°F (39.4°C) or higher often warrants a hospital visit, particularly if accompanied by other concerning symptoms. For children, especially infants, a lower temperature might be considered high enough to seek emergency care. Hospitals manage high fevers by identifying the root cause and providing comprehensive care.

Initial Assessment and Triage

Upon arrival at a hospital, individuals experiencing a high fever undergo triage. This rapid evaluation by a healthcare professional, often a nurse, determines the urgency of their condition and prioritizes care. During this phase, vital signs are measured, including temperature, heart rate, respiratory rate, and blood pressure, to assess the patient’s physiological state.

A brief medical history is also collected, including details about the fever’s onset, duration, associated symptoms, and existing medical conditions. This information helps the medical team understand the patient’s immediate needs and potential risks. Triage ensures those with the most severe conditions receive prompt attention, while others are attended to based on their assessed urgency.

Identifying the Cause

Identifying the underlying cause of a high fever is central to hospital care, as effective treatment depends on an accurate diagnosis. Healthcare providers initiate diagnostic procedures to pinpoint the fever’s source. Blood tests, including a complete blood count (CBC), are ordered to assess white blood cell levels, which can indicate infection or inflammation.

Blood cultures identify bacterial or fungal bloodstream infections. Inflammatory markers, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR), are also measured to detect systemic inflammation. Urine tests, including urinalysis and cultures, help identify urinary tract infections.

Imaging studies like chest X-rays check for pneumonia or other lung conditions. Depending on the suspected cause and patient symptoms, advanced imaging like computed tomography (CT) scans or ultrasounds may visualize internal organs for abscesses or abnormalities. If meningitis or encephalitis is suspected, a lumbar puncture (spinal tap) may analyze cerebrospinal fluid.

Treatment Strategies

Hospital treatment for a high fever involves two primary approaches: managing the fever itself and addressing its underlying cause. For symptomatic management, medications like acetaminophen (paracetamol) or ibuprofen are commonly administered to reduce body temperature and alleviate discomfort. Physical cooling methods, such as cool compresses or cooling blankets, may also be employed for very high or persistent fevers.

Addressing the cause involves targeted therapies based on the diagnosis. If a bacterial infection is identified, broad-spectrum antibiotics are typically started promptly, with adjustments made once specific culture results are available. For viral infections, antiviral medications may be prescribed, such as for influenza or herpes simplex virus.

If an inflammatory condition is the root cause, anti-inflammatory drugs or immunomodulating therapies might be initiated. The goal is to eliminate the fever’s source, leading to a sustained reduction in body temperature and symptom resolution. Treatment is tailored to each patient’s diagnosis and clinical presentation.

Ongoing Care and Monitoring

Once initial treatments are underway, continuous care and monitoring are integral to managing a patient with a high fever in a hospital setting. Healthcare staff regularly monitor vital signs, which may include continuous electronic monitoring or frequent manual checks, to track the patient’s response to treatment and detect any changes in condition. This observation helps identify potential complications or treatment plan adjustments.

Fluid management is another important aspect; intravenous fluids are often administered to prevent dehydration, particularly when a patient cannot adequately consume liquids orally due to fever. Pain management ensures the patient remains comfortable throughout their recovery. Nurses and doctors routinely assess symptoms, review laboratory results, and modify medications or care strategies.

Discharge and Next Steps

When a patient’s condition stabilizes and the fever resolves, the healthcare team evaluates their readiness for hospital discharge. Discharge criteria include stable vital signs, a sustained reduction in fever, and successful initiation of treatment for the underlying cause. Before leaving, patients receive comprehensive discharge instructions to support their continued recovery at home.

These instructions detail medication schedules, including dosages and frequency, and outline potential side effects to watch for. Patients are also advised on warning signs necessitating a return to the emergency department or immediate medical attention. Follow-up appointments with primary care physicians or specialists are scheduled to ensure ongoing monitoring and complete resolution of the condition.
