ICD-10: P36

Bacterial sepsis in newborns, classified under ICD-10 code P36, is a critical condition that requires immediate medical attention. This condition is characterized by a systemic inflammatory response to bacterial infection in neonates, which can lead to severe complications if not promptly treated.

Clinical Description

Definition

Bacterial sepsis in newborns refers to a serious infection that spreads throughout the body, leading to systemic inflammation. It is often caused by bacteria entering the bloodstream, which can occur during or after birth. The condition is particularly concerning in premature infants or those with low birth weight, as their immune systems are not fully developed.

Etiology

The most common pathogens associated with neonatal sepsis include:
- Group B Streptococcus (GBS): A leading cause of early-onset sepsis.
- Escherichia coli (E. coli): Frequently implicated in late-onset sepsis.
- Staphylococcus aureus: Can cause both early and late-onset infections.
- Listeria monocytogenes: Less common but can be severe.

Risk Factors

Several factors increase the risk of developing bacterial sepsis in newborns:
- Prematurity (born before 37 weeks of gestation)
- Low birth weight (less than 2500 grams)
- Maternal infections during pregnancy (e.g., chorioamnionitis)
- Prolonged rupture of membranes before delivery
- Invasive procedures (e.g., catheterization)

Clinical Presentation

Symptoms

The clinical presentation of bacterial sepsis in newborns can vary but often includes:
- Temperature instability (hypothermia or fever)
- Respiratory distress (e.g., tachypnea, grunting)
- Poor feeding or lethargy
- Irritability or decreased responsiveness
- Jaundice
- Abdominal distension

Diagnosis

Diagnosis typically involves:
- Clinical evaluation: Assessing symptoms and physical examination findings.
- Laboratory tests: Blood cultures, complete blood count (CBC), and inflammatory markers (e.g., C-reactive protein).
- Imaging studies: In some cases, ultrasound or X-rays may be used to identify sources of infection.

Management

Treatment

Management of bacterial sepsis in newborns generally includes:
- Antibiotic therapy: Initiating broad-spectrum antibiotics as soon as sepsis is suspected, often before culture results are available.
- Supportive care: Providing respiratory support, maintaining body temperature, and ensuring adequate nutrition.
