Sepsis neonatorum

Sepsis neonatorum, also known as neonatal sepsis, is a type of sepsis that occurs in newborn infants. It is a severe and life-threatening condition characterized by the body's systemic response to an infection. This condition is particularly dangerous due to the immature immune system of newborns, making them more susceptible to infections and less capable of fighting them off. Sepsis neonatorum can be caused by a variety of bacterial, viral, and fungal pathogens.

Causes and Risk Factors

The causes of sepsis neonatorum can be broadly classified into two categories based on the timing of infection: early-onset and late-onset. Early-onset sepsis occurs within the first week of life and is often acquired from the mother, either in utero or during childbirth. Common pathogens include Group B Streptococcus, Escherichia coli, and Listeria monocytogenes. Late-onset sepsis occurs after the first week of life and can be acquired from the environment or through invasive procedures. The risk factors for sepsis neonatorum include premature birth, low birth weight, prolonged rupture of membranes, and maternal infections.

Symptoms

The symptoms of sepsis neonatorum can be nonspecific and include temperature instability, respiratory distress, feeding difficulties, lethargy, and irritability. Due to the nonspecific nature of these symptoms, early diagnosis and treatment are crucial for survival.

Diagnosis

Diagnosis of sepsis neonatorum involves a combination of clinical assessment and laboratory tests. Blood cultures are the gold standard for identifying the causative organism. Other diagnostic tests may include complete blood count (CBC), C-reactive protein (CRP) levels, and lumbar puncture to rule out meningitis.

Treatment

Treatment of sepsis neonatorum typically involves prompt administration of broad-spectrum antibiotics while awaiting culture results. Once the causative organism is identified, antibiotic therapy can be tailored accordingly. Supportive care, including oxygen therapy, fluid management, and nutritional support, is also critical in the management of affected infants.

Prevention

Preventive measures for sepsis neonatorum include screening and treating pregnant women for infections, administering intrapartum antibiotic prophylaxis to women at risk of transmitting Group B Streptococcus, and employing sterile techniques during childbirth and invasive procedures in newborns.

Prognosis

The prognosis of sepsis neonatorum depends on several factors, including the causative organism, the timeliness of diagnosis and treatment, and the presence of any underlying conditions. Despite advances in neonatal care, sepsis remains a leading cause of morbidity and mortality in newborns.
