Neonatal Sepsis Prevention and Management

15 recomendaciones•5,905 vistas
Neonatal sepsis is a clinical syndrome of infection in the first four weeks of life that can cause multi-organ dysfunction and death if not recognized and treated early. It is a significant problem in India, causing 20% of neonatal deaths. The presentation and risk factors differ between early onset sepsis (<72 hours) which is usually caused by maternal pathogens and late onset sepsis (>72 hours) which is usually nosocomial. Treatment involves supportive care, administration of antibiotics, and recognition/prevention of risk factors like prematurity and invasive procedures. Handwashing and maintaining sterile techniques are essential to prevent hospital-acquired infections.
