Insights

Children with persistent fever after antipyretic medication are more likely to have bacteremia. This study highlights the importance of monitoring fever response in pediatric emergency departments to identify potential bloodstream infections.

Area of Science:

  • Pediatric Emergency Medicine
  • Infectious Diseases
  • Clinical Microbiology

Background:

  • Fever is a common symptom in children presenting to emergency departments.
  • Antipyretics are frequently used to manage fever.
  • The association between fever resolution and underlying bacteremia requires further investigation.

Purpose of the Study:

  • To investigate the relationship between the lack of fever response to antipyretics and the presence of bacteremia in children.
  • To determine if persistent fever after antipyretic administration is a predictor of bacteremia.

Main Methods:

  • Cross-sectional study design.
  • Inclusion of children with initial temperature ≥38°C presenting to a pediatric emergency department (ED).
  • Analysis of blood cultures and fever resolution at 180 and 240 minutes post-antipyretic administration, adjusting for covariates.

Main Results:

  • Out of 6319 febrile children, 242 (3.8%) had bacteremia.
  • Children remaining febrile at 180 minutes had an adjusted odds ratio of 1.6 for bacteremia.
  • Children remaining febrile at 240 minutes had an adjusted odds ratio of 1.7 for bacteremia.

Conclusions:

  • Lack of fever resolution following antipyretic use is associated with a higher likelihood of bacteremia in children.
  • Persistent fever in pediatric ED patients may indicate underlying bloodstream infections.
  • Monitoring antipyretic response is crucial for identifying children with bacteremia.

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Increased Body Temperature01:25

Increased Body Temperature

A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Types of Fever

Fever can be triggered by several factors, including infections, nervous system disorders, certain cancers, blood diseases like leukemia, embolism, thrombosis, heatstroke, dehydration, surgical trauma, crushing injuries, and allergic reactions.

Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...
