Management of Neonates With Suspected or Proven Early Onset Bacterial Sepsis From the American Academy of Pediatrics. Pathogenesis and Epidemiology of Early Onset Sepsis. Before birth, the fetus optimally is maintained in a sterile environment. Organisms causing early onset sepsis ascend from the birth canal either when the amniotic membranes rupture or leak before or during the course of labor, resulting in intra amniotic infection. Commonly referred to as chorioamnionitis, intra amniotic infection indicates infection of the amniotic fluid, membranes, placenta, andor decidua. Group B streptococci GBS can also enter the amniotic fluid through occult tears. Chorioamnionitis is a major risk factor for neonatal sepsis. The routine newborn assessment should include an examination for size, macrocephaly or microcephaly, changes in skin color, signs of birth trauma, malformations. Bronchopulmonary dysplasia BPD formerly chronic lung disease of infancy is a chronic lung disease in which premature infants, usually those who were treated with. Background Bronchopulmonary dysplasia is associated with ventilation and oxygen treatment. This randomized trial investigated whether nasal continuous positive airway.

Sepsis can begin in utero when the fetus inhales or swallows infected amniotic fluid. The neonate can also develop sepsis in the hours or days after birth when colonized skin or mucosal surfaces are compromised. The essential criterion for the clinical diagnosis of chorioamnionitis is maternal fever. Other criteria are relatively insensitive. When defining intra amniotic infection chorioamnionitis for clinical research studies, the diagnosis is typically based on the presence of maternal fever of greater than 3. C 1. 00. 4F and at least two of the following criteria maternal leukocytosis greater than 1. These thresholds are associated with higher rates of neonatal and maternal morbidity. Nonetheless, the diagnosis of chorioamnionitis must be considered even when maternal fever is the sole abnormal finding. Adobe Indesign Cs6 Portable Corel. Although fever is common in women who receive epidural anesthesia 1. Furthermore, most of these women with histologic chorioamnionitis do not have a positive placental culture. The incidence of clinical chorioamnionitis varies inversely with gestational age. In the National Institute of Child Health and Human Development Neonatal Research Network, 1. The major risk factors for chorioamnionitis include low parity, spontaneous labor, longer length of labor and membrane rupture, multiple digital vaginal examinations especially with ruptured membranes, meconium stained amniotic fluid, internal fetal or uterine monitoring, and presence of genital tract microorganisms eg, Mycoplasma hominis. At term gestation, less than 1 of women with intact membranes will have organisms cultured from amniotic fluid. The rate can be higher if the integrity of the amniotic cavity is compromised by procedures before birth eg, placement of a cerclage or amniocentesis. In women with preterm labor and intact membranes, the rate of microbial invasion of the amniotic cavity is 3. PPROM, the rate may be as high as 7. Many of the pathogens recovered from amniotic fluid in women with preterm labor or PPROM eg, Ureaplasma species or Mycoplasma species do not cause early onset sepsis. However, both Ureaplasma and Mycoplasma organisms can be recovered from the bloodstream of infants whose birth weight is less than 1. When a pathogen eg, GBS is recovered from amniotic fluid, the attack rate of neonatal sepsis can be as high as 2. Infants born to women with PPROM who are colonized with GBS have an estimated attack rate of 3. The major risk factors for early onset neonatal sepsis are preterm birth, maternal colonization with GBS, rupture of membranes 1. Other variables include ethnicity ie, black women are at higher risk of being colonized with GBS, low socioeconomic status, male sex, and low Apgar scores. Preterm birthlow birth weight is the risk factor most closely associated with early onset sepsis. Infant birth weight is inversely related to risk of early onset sepsis. The increased risk of early onset sepsis in preterm infants is also related to complications of labor and delivery and immaturity of innate and adaptive immunity. Diagnostic Testing for Sepsis. The clinical diagnosis of sepsis in the neonate is difficult, because many of the signs of sepsis are nonspecific and are observed with other noninfectious conditions. Although a normal physical examination is evidence that sepsis is not present,1. Available diagnostic testing is not helpful in deciding which neonate requires empirical antimicrobial therapy but can assist with the decision to discontinue treatment. Blood Culture. A single blood culture in a sufficient volume is required for all neonates with suspected sepsis. Data suggest that 1. L of blood should be the minimum volume drawn for culture when a single pediatric blood culture bottle is used. Dividing the specimen in half and inoculating aerobic and anaerobic bottles is likely to decrease the sensitivity. Although 0. 5 m. L of blood has previously been considered acceptable, in vitro data from Schelonka et al demonstrated that 0. L would not reliably detect low level bacteremia 4 colony forming units CFUm. L or less. 2. 3 Furthermore, up to 2. CFUm. L, and two thirds of infants younger than 2 months of age have colony counts lt 1. CFUm. L. 2. 4,2. Neal et al demonstrated that more than half of blood specimens inoculated into the aerobic bottle were less than 0. Audaces Moldes here. L. 2. 6 A study by Connell et al indicated that blood cultures with an adequate volume were twice as likely to yield a positive result. A blood culture obtained through an umbilical artery catheter shortly after placement for other clinical indications is an acceptable alternative to a culture drawn from a peripheral vein. The risk of recovering a contaminant is greater with a blood culture drawn from an umbilical vein. There are, however, data to suggest that a blood culture drawn from the umbilical vein at the time of delivery using a doubly clamped and adequately prepared segment of the cord is a reliable alternative to a culture obtained peripherally. Urine Culture. A urine culture should not be part of the sepsis workup in an infant with suspected early onset sepsis. Unlike urinary tract infections in older infants which are usually ascending infections, urinary tract infections in newborn infants are attributable to seeding of the kidney during an episode of bacteremia. Gastric Aspirates. The fetus swallows 5. L of amniotic fluid each day. Therefore, if there are white blood cells present in amniotic fluid, they will be present in gastric aspirate specimens at birth. However, these cells represent the maternal response to inflammation and have a poor correlation with neonatal sepsis. Gram stains of gastric aspirates to identify bacteria are of limited value and are not routinely recommended. Body Surface Cultures. Bacterial cultures of the axilla, groin, and the external ear canal have a poor positive predictive accuracy. They are expensive and add little to the evaluation of an infant with possible bacterial sepsis. Tracheal Aspirates. Cultures and Gram stains of tracheal aspirate specimens may be of value if obtained immediately after endotracheal tube placement. Once an infant has been intubated for several days, tracheal aspirates are of no value in the evaluation of sepsis. Lumbar Puncture. The decision to perform a lumbar puncture in a neonate with suspected early onset sepsis remains controversial. In the high risk, healthy appearing infant, data suggest that the likelihood of meningitis is extremely low. In the infant with clinical signs that are thought to be attributable to a noninfectious condition, such as respiratory distress syndrome, the likelihood of meningitis is also low. However, in bacteremic infants, the incidence of meningitis may be as high as 2.
