Neonatal sepsis

Overview Of Neonatal sepsis

Neonatal sepsis is a life-threatening condition in newborns characterized by a systemic infection during the first 28 days of life. It can be classified as: - **Early-onset sepsis (EOS)**: Occurs within the first 72 hours of life, often acquired during delivery. - **Late-onset sepsis (LOS)**: Occurs after 72 hours of life, typically due to environmental exposure. --- ### **Causes**: - **Bacterial infections** (most common): - *Group B Streptococcus* (*GBS*). - *Escherichia coli*. - *Listeria monocytogenes*. - *Klebsiella species*. - **Viral infections**: - Herpes simplex virus (HSV). - Cytomegalovirus (CMV). - **Fungal infections** (in immunocompromised neonates): - *Candida species*. --- ### **Symptoms**: Symptoms may be nonspecific and include: - Poor feeding or refusal to feed. - Hypothermia or fever. - Lethargy or irritability. - Respiratory distress (e.g., grunting, apnea, or rapid breathing). - Jaundice (yellowing of the skin). - Poor perfusion (pale, cold extremities). - Seizures. - Abdominal distension or vomiting. --- ### **Risk_Factors**: - **Maternal factors**: - Prolonged rupture of membranes (>18 hours). - Chorioamnionitis or maternal infection. - Maternal colonization with *Group B Streptococcus*. - **Neonatal factors**: - Premature birth (<37 weeks gestation). - Low birth weight (<2500 grams). - Need for invasive procedures (e.g., central lines, mechanical ventilation). - **Environmental factors**: - Poor hygiene or inadequate infection control in healthcare settings. --- ### **Diagnosis**: - **Clinical evaluation**: Identifying nonspecific symptoms. - **Laboratory tests**: - Blood cultures (to identify causative organisms). - Complete blood count (CBC) with differential. - C-reactive protein (CRP) or procalcitonin levels. - **Other tests**: - Lumbar puncture for cerebrospinal fluid analysis (if meningitis is suspected). - Chest X-ray for suspected pneumonia. - Urine cultures in late-onset sepsis. --- ### **Treatment**: - **Empirical antibiotic therapy**: - Early-onset sepsis: Ampicillin + Gentamicin. - Late-onset sepsis: Consider Vancomycin + a broad-spectrum antibiotic (e.g., third-generation cephalosporin). - **Supportive care**: - Intravenous fluids and electrolyte management. - Respiratory support if needed. - Antifungal or antiviral treatment based on suspected pathogens. --- ### **Prognosis**: - **Early diagnosis and treatment**: Generally good outcomes for term neonates. - **Delayed treatment or severe cases**: Can lead to significant morbidity (e.g., cerebral palsy, hearing loss) or mortality. --- ### **Complications**: - Meningitis. - Septic shock. - Multiorgan failure. - Long-term neurodevelopmental disabilities. --- ### **Prevention**: - Routine maternal screening for *Group B Streptococcus* during pregnancy. - Prophylactic intrapartum antibiotics for GBS-positive mothers. - Strict aseptic techniques during delivery and neonatal care. - Early treatment of maternal infections. --- ### **Related_Diseases**: - Neonatal meningitis. - Neonatal pneumonia. - Congenital infections (e.g., TORCH infections). --- Let me know if you need further details or references!
