Introduction
Fever in a newborn is a critical clinical sign that requires immediate attention and thorough assessment by healthcare professionals. Unlike older children and adults, newborns have immature immune systems and underdeveloped thermoregulatory mechanisms, making them particularly vulnerable to infections and complications associated with elevated body temperature.
For nursing professionals, understanding how to properly assess, manage, and provide care for newborns with fever is essential to prevent serious complications and ensure optimal outcomes.
This comprehensive guide will equip nursing students with the knowledge and tools necessary to effectively care for newborns presenting with fever, from initial assessment to ongoing management and parental education.
Definition and Classification
What is Fever in a Newborn?
A fever in a newborn is formally defined as a rectal or forehead (temporal) temperature of 100.4°F (38°C) or higher. This temperature threshold is crucial as it distinguishes normal temperature variation from pathological elevation requiring medical intervention.
Normal Temperature Ranges in Newborns
Normal body temperature in newborns varies slightly based on the measurement method:
| Measurement Method | Normal Range | Fever Threshold |
|---|---|---|
| Rectal (Gold Standard) | 97.9°F – 100.3°F (36.6°C – 37.9°C) | ≥ 100.4°F (38°C) |
| Axillary (Armpit) | 97.5°F – 99.3°F (36.4°C – 37.4°C) | ≥ 99.4°F (37.4°C) |
| Temporal Artery (Forehead) | 97.5°F – 100.3°F (36.4°C – 37.9°C) | ≥ 100.4°F (38°C) |
| Tympanic (Ear) | 97.7°F – 100.3°F (36.5°C – 37.9°C) | ≥ 100.4°F (38°C) |
Note: Rectal temperature measurement is considered the most accurate method for newborns but should be performed carefully by trained healthcare professionals.
Classification of Fever in Newborns
Based on severity:
- Low-grade fever: Temperature between 100.4°F (38°C) and 102.2°F (39°C)
- Moderate fever: Temperature between 102.2°F (39°C) and 104°F (40°C)
- High fever: Temperature above 104°F (40°C)
Based on onset and duration:
- Acute fever: Sudden onset, lasting less than 7 days
- Persistent fever: Lasting more than 7 days
- Recurrent fever: Episodes of fever separated by fever-free intervals of at least 24 hours
IMPORTANT: Any fever in a newborn under 28 days of age is considered a medical emergency and requires immediate evaluation, regardless of severity or duration.
Pathophysiology of Fever in Newborns
Understanding the underlying mechanisms of fever in newborns is essential for appropriate nursing assessment and interventions.
Thermoregulation in Newborns
Newborns have limited ability to regulate their body temperature due to:
- Immature hypothalamic temperature control center
- Higher body surface area to mass ratio (increased heat loss)
- Limited subcutaneous fat (reduced insulation)
- Inability to shiver effectively
- Limited ability to sweat
- Reduced metabolic responses to cold stress
Fever Generation Process
- Pathogen introduction: Infection triggers immune response
- Pyrogen release: Immune cells release endogenous pyrogens (IL-1, IL-6, TNF-α)
- Hypothalamic signaling: Pyrogens cross blood-brain barrier and stimulate prostaglandin E2 (PGE2) production
- Thermostat elevation: PGE2 increases hypothalamic temperature set point
- Physiologic response: Body initiates heat-conserving and heat-generating mechanisms
- Fever manifestation: Core temperature rises to match new set point
Clinical Insight: In newborns, the fever response may be blunted or absent even in serious infections, while in other cases, environmental factors can cause temperature elevation without infection. This makes careful assessment vital.
Etiology and Risk Factors

Risk Factors for Neonatal Fever and Sepsis
Maternal Risk Factors
- Maternal GBS colonization
- Chorioamnionitis
- Prolonged rupture of membranes (>18 hours)
- Premature rupture of membranes
- Maternal fever during labor (>38°C/100.4°F)
- Inadequately treated maternal UTI
- Limited or no prenatal care
- Intrapartum antibiotic prophylaxis less than 4 hours before delivery
Neonatal Risk Factors
- Prematurity (<37 weeks gestation)
- Low birth weight (<2500g)
- Male gender
- Congenital anomalies
- Invasive procedures (central lines, intubation)
- Prolonged hospitalization
- Twin or multiple birth
- Galactosemia
- Perinatal asphyxia
Important Distinction: Early-onset sepsis (within first 72 hours) is typically associated with maternal risk factors and vertical transmission, while late-onset sepsis (after 72 hours) is more commonly associated with postnatal environmental exposure and healthcare-associated infections.
Clinical Manifestations
Fig 1: Clinical Signs of Fever in Newborns
Recognizing the clinical manifestations of fever in newborns is crucial, as signs can be subtle and nonspecific. Unlike older children or adults, newborns may not display typical signs of infection despite serious illness.
Primary Signs and Symptoms
Thermoregulatory Signs
- Elevated temperature (≥38°C/100.4°F rectal)
- Temperature instability (fluctuations)
- Hypothermia (can be a sign of severe infection)
- Warm to touch, especially trunk
- Flushed skin or mottling
Behavioral Changes
- Lethargy or decreased activity
- Irritability and inconsolable crying
- Poor feeding or feeding refusal
- Decreased responsiveness
- Altered sleep patterns
Secondary Signs by System
| Body System | Clinical Manifestations |
|---|---|
| Respiratory |
|
| Cardiovascular |
|
| Gastrointestinal |
|
| Neurological |
|
| Integumentary |
|
Critical Nursing Alert: The absence of fever does not rule out serious infection in newborns. Hypothermia can be a sign of overwhelming infection. Always assess the whole clinical picture rather than relying on temperature alone.
Nursing Assessment
A thorough nursing assessment is critical for early detection and appropriate management of fever in newborns. The assessment should be systematic and comprehensive.
Temperature Measurement Techniques
| Method | Procedure | Considerations |
|---|---|---|
| Rectal |
|
|
| Axillary |

- Document prior antibiotic use or recent procedures
Diagnostic Studies
Nurses should be familiar with common diagnostic studies ordered for newborns with fever:
| Study | Purpose | Nursing Considerations |
|---|---|---|
| Complete Blood Count (CBC) | Assess for leukocytosis, leukopenia, thrombocytopenia, anemia | Collect before antibiotics if possible; minimize blood volume |
| Blood Culture | Identify causative organisms | Sterile collection technique; adequate volume (1-2 mL); before antibiotics |
| Urinalysis and Culture | Identify urinary tract infections | Sterile catheterization or suprapubic aspiration needed |
| Lumbar Puncture | Evaluate for meningitis | Position support; monitor vital signs; comfort measures after procedure |
| C-reactive Protein (CRP) | Non-specific inflammation marker | May be elevated 6-12 hours after onset of infection |
| Procalcitonin | Early marker of bacterial infection | More specific than CRP; rises within 2-4 hours of infection |
| Chest X-ray | Assess for pneumonia | Minimize exposure; proper positioning and immobilization |
| Viral Studies | Identify viral pathogens | May include nasal swabs, blood PCR for HSV, enterovirus |
Clinical Tip: When caring for a febrile newborn, remember that lab values may be different from older children. For example, a normal white blood cell count in a newborn is 9,000-30,000 cells/μL, and bilirubin levels are naturally higher.
Nursing Diagnosis
Based on the comprehensive assessment of a newborn with fever, several nursing diagnoses may be appropriate. These diagnoses guide the development of specific interventions and care plans.
Primary Nursing Diagnoses for Newborns with Fever
1. Hyperthermia related to infectious process as evidenced by body temperature ≥38°C (100.4°F)
This addresses the primary presenting problem of elevated body temperature and focuses interventions on temperature management.
2. Risk for Ineffective Thermoregulation related to immature regulatory mechanisms and infectious process
This diagnosis recognizes the vulnerability of newborns to temperature instability, including both hyper- and hypothermia.
3. Risk for Deficient Fluid Volume related to increased metabolic rate, decreased oral intake, and insensible losses
Addresses potential dehydration risk associated with fever, especially if the newborn is feeding poorly.
4. Risk for Infection (Sepsis) related to immature immune system and presence of infectious organisms
Recognizes the risk of progression from localized infection to systemic infection.
5. Imbalanced Nutrition: Less Than Body Requirements related to increased metabolic needs and decreased feeding
Addresses nutritional concerns due to increased caloric needs during fever and possible decreased intake.
6. Interrupted Family Processes related to crisis of infant illness and hospitalization
Recognizes the impact of the newborn’s illness on the family unit and parent-infant bonding.
7. Anxiety (Parental) related to unknown outcome of infant’s condition
Addresses the psychological impact on parents when their newborn is ill.
8. Deficient Knowledge related to lack of information about newborn fever management and warning signs
Focuses on educational needs of parents/caregivers regarding care of the infant.
Documentation Tip: When writing nursing diagnoses for newborns with fever, include all three components: problem statement, related factors (etiology), and defining characteristics (evidence). This ensures a comprehensive care approach.
Nursing Interventions
Effective nursing care for newborns with fever requires a combination of assessment, monitoring, therapeutic interventions, and family support. Below are evidence-based nursing interventions organized by priority.

Medical Management and Treatment
While nursing care is fundamental for newborns with fever, medical management addresses the underlying causes. Nurses need to understand the medical approach to collaborate effectively in the care team.
Initial Management Approach
The approach to managing fever in newborns depends on the infant’s age, clinical appearance, and risk factors:
| Age Group | Standard Approach |
|---|---|
| 0-28 days (Neonates) |
|
| 29-60 days |
|
| 61-90 days |
|
Antimicrobial Therapy
Empiric Antimicrobial Therapy
Initial antimicrobial therapy for febrile newborns is broad-spectrum until pathogen identification:
| Age/Condition | First-Line Therapy | Alternative Therapy |
|---|---|---|
| Early-onset sepsis (<72 hours) | Ampicillin + Gentamicin | Ampicillin + Cefotaxime |
| Late-onset sepsis (>72 hours) | Ampicillin + Cefotaxime | Vancomycin + Gentamicin |
| Suspected meningitis | Ampicillin + Cefotaxime | Ampicillin + Gentamicin + Acyclovir (if HSV suspected) |
| Hospital-acquired infection | Vancomycin + Gentamicin | Based on local antibiogram |
Key Considerations for Antimicrobial Therapy
- Dosing is weight-based and requires precise calculation
- Renal function monitoring is essential with aminoglycosides
- Duration typically 7-14 days depending on infection site and organism
- De-escalation to narrower coverage once cultures identify specific pathogen
- Therapeutic drug monitoring may be needed for certain antibiotics
Supportive Care
Fluid and Electrolyte Management
- IV fluid rate based on weight and physiologic needs
- Typically 60-100 mL/kg/day plus deficit replacement
- Regular electrolyte monitoring
- Adjustment based on clinical status
Respiratory Support
- Oxygen supplementation if needed
- Positioning for optimal breathing
- Potential need for CPAP or ventilation if respiratory failure
- Regular assessment of respiratory status
Nutritional Support
- NPO status initially for severely ill newborns
- Early enteral feeding when clinically stable
- Parenteral nutrition if prolonged NPO status
- Breast milk preferred when feeding initiated
Seizure Management
- Anticonvulsant therapy if seizures present
- Common agents: Phenobarbital, Levetiracetam
- Close neurological monitoring
- EEG monitoring in cases of suspected seizures
Monitoring Response to Treatment
Signs of Improvement
- Normalization of temperature
- Improved feeding
- Decreased irritability
- Stable vital signs
- Improved activity level
- Negative follow-up cultures
- Normalization of laboratory values
Treatment Failure Signs
- Persistent or recurrent fever despite 48 hours of antibiotics
- Worsening clinical status
