Introduction
Fever, also known as pyrexia, may recur in children a few hours after subsiding. This could be caused by bacterial infection, viral infection, pharyngitis, gastroenteritis, pneumonia, or other reasons. Treatment should be based on the specific condition. In summary, the underlying causes for the aforementioned issues may vary; therefore, it is recommended that patients first visit a正规 hospital for proper diagnosis and treatment.
Fever, also known as pyrexia, may recur in children several hours after subsiding due to various causes such as bacterial cold, viral cold, pharyngitis, gastroenteritis, or pneumonia. Treatment should be based on the specific condition. Detailed analysis is as follows:
1. Bacterial Cold
This is often associated with bacterial infection. After infection, the body typically develops a series of inflammatory responses leading to fever. If the underlying inflammation persists, it's common for a child's fever to return about three hours after taking antipyretic medication. Anti-inflammatory treatment can be achieved by oral administration of medications such as amoxicillin-clavulanate potassium granules or cefixime granules. Once the inflammatory factors are eliminated, the fever usually improves.
2. Viral Cold
This is typically caused by viral infections and may present with symptoms such as runny nose, sneezing, nasal congestion, and fever. It can also manifest as recurring fever approximately three hours after taking antipyretics. Antiviral treatment under medical guidance may include oseltamivir phosphate granules or ribavirin granules.
3. Pharyngitis
Pharyngitis may occur when persistent inflammation irritates the pharyngeal mucosa, causing congestion and swelling. Under a doctor’s guidance, medications such as cefdinir dispersible tablets, cefradine capsules, or cefuroxime axetil tablets can be used for treatment.
4. Gastroenteritis
Gastroenteritis could also cause the aforementioned symptoms in infants, usually due to consumption of contaminated food. Besides recurrent fever, affected children commonly experience nausea, vomiting, and diarrhea. If axillary temperature exceeds 38.5°C, antipyretic drugs such as ibuprofen suspension, acetaminophen tablets, or diclofenac sodium sustained-release tablets may be taken as directed by a physician to alleviate fever.
5. Pneumonia
Pneumonia may lead to inflammation or swelling of lung tissue and pus accumulation in alveoli. Treatment under medical advice may involve medications such as azithromycin dispersible tablets, levofloxacin hydrochloride capsules, or moxifloxacin hydrochloride tablets.
In summary, the above conditions have different potential causes; therefore, it is recommended that patients first visit a正规 hospital for proper diagnosis before receiving treatment tailored to their specific situation.
