Diagnosis and Management of Clinical Chorioamnionitis

After adjusting for potential confounding variables and depending on the specific confounders considered, some of the risk factors for chorioamnionitis identified in older studies no longer demonstrate an association in recent studies. Multivariate risk assessment and increased reliance on clinical acot may safely decrease the number of well-appearing term newborns treated empirically with antibiotics 5, 12, Use of this Web site constitutes acceptance of our Terms of Use.

Background Intraamniotic infection, also known as chorioamnionitis, is an infection with resultant inflammation of any combination of the amniotic fluid, placenta, fetus, fetal membranes, or decidua.

A research agenda was proposed to further refine the definition and management of this complex group of conditions. In Januarythe Eunice Kennedy Shriver National Institute of Child Health and Human Development invited an expert panel to a workshop to address numerous knowledge gaps and to provide evidence-based guidelines for the diagnosis and management of pregnant women with what had been commonly called chorioamnionitis and the neonates born to these women. Chorioamnionitis increases neonatal morbidity in pregnancies complicated by preterm premature rupture of membranes.

Maternal intraamniotic infection is reasonably sensitive but lacks specificity with regard to the diagnosis of neonatal sepsis, particularly among preterm infants. The panel noted that the term chorioamnionitis has been used to label a heterogeneous array of conditions characterized by infection and inflammation or both with a consequent great variation in clinical practice for mothers and their newborns.

Funisitis, also a histopathologic diagnosis, is the extension of infection or inflammation to the umbilical cord.

Cell Host Microbe ; More recent data suggest that the relative risk for intraamniotic infection and neonatal infection may increase after 40 completed weeks of gestation 3— 5. Support Center Support Center.

Neither ACOG nor its officers, directors, members, employees, or agents will be liable for any loss, damage, or claim with respect to any liabilities, including direct, special, indirect, or consequential damages, incurred in connection with this chorioamnionjtis or reliance on the information presented. Am J Perinatol ; Anterograde infection from the peritoneum via the fallopian tubes has also been postulated [ 22 ].

Intrapartum Management of Intraamniotic Infection – ACOG

For these reasons, placental pathology should be performed to confirm suspected chorioamnionitis even if amniotic fluid culture is negative. Recommendations The American College of Obstetricians and Gynecologists makes the following recommendations: Newer pediatric recommendations rely less on the clinical diagnosis of suspected intraamniotic infection, and more on consideration of a variety of risk factors and newborn clinical status to determine neonatal management.

Antibiotic therapy for reduction of infant morbidity after preterm premature rupture of the membranes. This is particularly important during the intrapartum period since fetal acidosis in the setting of fever has been associated with a marked increase in the incidence of neonatal encephalopathy [ 87 ].

Diagnosis of confirmed histologic intraamniotic infection in the postpartum period does not alter postdelivery maternal treatment. A randomized controlled trial. Chorioamnionitis that is subclinical by definition does not present the above clinical signs but may manifest as preterm labor or, even more commonly, as preterm premature rupture of membranes PPROM.

This information is designed as an educational resource to aid clinicians in providing obstetric and gynecologic care, and use of this information is voluntary. The use of vaginal pool fluid after premature membrane rupture for these acof e. Edwards RK, Duff P. The exact mechanism of epidural fever is unknown, but it is thought to be the result of epidural sympathetic blockade of thermoregulatory processes such as sweating [ 24 ].

A comparative study of the diagnostic performance of amniotic fluid glucose, white blood cell count, interleukin-6, and gram stain in the detection of microbial invasion in patients with preterm premature rupture of membranes. Meconium-stained amniotic fluid is associated chorioamnionitiis puerperal infections. Definition Chorioamnionitis or intraamniotic infection is an acute inflammation of the membranes and chorion of the placenta, typically due to ascending polymicrobial bacterial infection in the setting of membrane rupture.

Am J Dis Child. Intrapartum antibiotics also have been shown to decrease maternal febrile morbidity and length of hospital stay. However, their utility for the diagnosis or prediction of choriamnionitis as part of routine clinical practice is not established. Chorioamnionitis leads to a 2 to 3-fold increased risk for cesarean delivery and 2 to 4-fold increase in endomyometritis, wound infection, pelvic abscess, bacteremia and postpartum hemorrhage [ 1253 — 56 ].

The Alabama Preterm Birth Study: Chorioamnionitis is associated with postpartum maternal infections and potentially devastating fetal complications including premature birth, neonatal sepsis and cerebral palsy. However, most cases of intraamniotic infection detected and managed by obstetrician—gynecologists or other obstetric care providers will be noted among term patients in labor.

The diagnosis of intraamniotic infection can be established objectively chorioamniontiis amniotic fluid culture, or gram stain, or both and biochemical analysis, but for most women at term who are in labor the diagnosis is primarily made using clinical criteria. American College of Obstetricians and Gynecologists.

Chorioamnionitis and intraamniotic cchorioamnionitis. Clinical chorioamnionitis carries adverse consequences affecting both the woman and her infant Figure 2. Obstetrician—gynecologists and other obstetric care providers also should consider consulting their local microbiology laboratory and infectious disease experts to ascertain whether there are alternative recommended regimens based on local antibiotic resistance patterns. Common antibiotic choices for treatment of suspected intraamniotic infection are listed in Table 1.

No change in the incidence of ampicillin-resistant, neonatal, early-onset sepsis over 18 years. An update on the prevalence of cerebral palsy: This suggests that the pathologic basis for epidural fever is chorioamnionitis [ 23 ].

Diagnosis and Management of Clinical Chorioamnionitis

Ten percent of women with chorioamnionitis have positive blood cultures bacteremia most commonly involving GBS and E. The frequency of microbial invasion of the amniotic cavity and histologic chorioamnionitis in women at term with chorioannionitis membranes in the presence or absence of labor. Intraamniotic infection is a common condition noted among preterm and term parturients.
