Introduction
Fever usually refers to an elevated body temperature. Prior to the onset of fever, symptoms such as runny nose and nasal congestion may appear, and body temperature may be at the upper limit of the normal range. This may then be followed by chills, shivering, and cold hands and feet, indicating that the body temperature is rising. Subsequently, the temperature reaches its peak, possibly accompanied by facial flushing and increased respiratory rate. Finally, the body's heat production becomes less than heat loss, resulting in a gradual decrease in temperature and profuse sweating.
Fever usually refers to an elevated body temperature. The recovery process of a baby's fever generally includes four stages: prodromal stage, rising phase, plateau phase, and defervescence phase.
1. Prodromal Stage
Prior to the onset of fever, some discomfort symptoms may appear, such as runny nose, sneezing, and nasal congestion. These may be accompanied by decreased appetite, reduced activity, and irritability. At this time, body temperature measurement may show values at the upper limit of the normal range.
2. Rising Phase
During this phase, the baby may feel cold, experience shivering, and have cold hands and feet. Appropriate warming measures are recommended to prevent excessive heat production. Body temperature readings typically begin to rise during this stage.
3. Plateau Phase
Body temperature reaches its peak during this stage, while heat production and dissipation in the body are roughly balanced. Symptoms may include flushed face and increased respiratory rate.
4. Defervescence Phase
Following timely intervention and treatment, the body's heat production usually becomes less than heat dissipation, leading to a gradual decrease in body temperature and often accompanied by profuse sweating. During this stage, it is important to ensure adequate rest and increased fluid intake to prevent electrolyte imbalances.
When a baby develops a fever, it is recommended that caregivers promptly seek medical guidance to complete relevant examinations, identify the underlying cause, and implement appropriate treatments to help alleviate symptoms, prevent worsening of the condition, and support recovery.
