Neonatal sepsis ppp

  1. 1. بسم الله الرحمن الرحيم Neonatal Sepsis BKTH Department of Pediatrics Dr. magdah & Dr. Amal Unite April 2010 By: Dr. Mohamed Eisam Elhag Mahmoud MBBS, Alneelain University Faculty of Medicine Note: Dr. Mohammed Isam Al-Hajj does not have any financial relationships to disclose nor will he discuss any non-approved drug or device uses.
  2. 2. Babies and Bacteria... What will I learn ? Pathology * Causes * Symptoms * Diagnosis * Treatments
  3. 3. Definition <ul><li>Neonatal sepsis is a clinical syndrome of systemic illness accompanied by bacteremia occurring in the first month of life. </li></ul>
  4. 4. Epidemiology <ul><li>Incidence : 1-8 cases per 1000 live births </li></ul><ul><li>Mortality: 50% </li></ul><ul><ul><li>13-69% world wide </li></ul></ul><ul><ul><li>13-15% of all neonatal deaths (US) (8 th cause) </li></ul></ul><ul><li>Morbidity: Meningitis occurs in one third of sepsis cases </li></ul><ul><li>Sex : males more </li></ul><ul><ul><li>Culture proven 2/1000 (3-8% of infants evaluated for sepsis); 10-20/1000 VLBW </li></ul></ul><ul><li>Age : premature infants </li></ul><ul><li>(1000-2000 g : 8-9/1000 </li></ul><ul><li><1000 g : 26/1000) </li></ul>
  5. 5. Pathophysiology <ul><li>Neonate immune deficiency </li></ul><ul><li>neutrophil, monocyte, macrophage, T cell, immunoglobulin, complement </li></ul><ul><li>physical and chemical barriers </li></ul><ul><li> Because of the interdependence of the immune response, these individual deficiencies of the various components of immune activity in the neonate cospire to create a hazardous situation for the neonate exposed to infectious threats !! </li></ul>
  6. 6. Classification <ul><li>Early onset sepsis (EOS): </li></ul><ul><ul><li>bacteria acquired before and during delivery </li></ul></ul><ul><ul><li>5-7/1000 live birth </li></ul></ul><ul><li>Late onset sepsis (LOS): </li></ul><ul><ul><li>bacteria acquired after delivery (Nosocomial or community) </li></ul></ul><ul><ul><li>20% of VLBW infants </li></ul></ul>
  7. 7. Early onset sepsis Late onset sepsis Pathogens Group B Streptococcus E. coli Haemophilus influenzae Listeria Virus, STD Coagulase negative staphylococcus Staphy. aureus E. coli Klebsiella Pseudomonas Enterobacter Baby in risk Term, near-term baby Preterm baby

  9. 9. Predisposing Factors <ul><li>Maternal/Obstetrical Factors </li></ul><ul><ul><li>General – socioeconomic status, poor prenatal care, vaginal flora, maternal substance abuse, known exposures, prematurity , twins </li></ul></ul><ul><ul><li>Maternal infections – chorioamnionitis (1-10% of pregnancies), fever (>38° C/100.4° F), sustained fetal tachycardia, venereal diseases, UTI/bacteriuria, foul smelling lochia, GBS+ (OR 204), other infections </li></ul></ul><ul><ul><li>Obstetrical manipulation – amniocentesis, amnioinfusion, prolonged labor, fetal monitoring, digital exams, previa/abruption? </li></ul></ul><ul><ul><li>Premature & Prolonged ROM, preterm labor </li></ul></ul>
