CLINICAL ACTIONS: The NICHD conducted a workshop in January to review evidence, with special consideration to avoid unnecessary. The American College of Obstetricians and Gynecologists (ACOG) published a Intraamniotic infection, also known as chorioamnionitis, is an. Historically, infection of the chorion, amnion, or both was termed ” chorioamnionitis.” Although this term remains in common use, the term.

No long-term follow-up data from this study has been reported. However, this relationship was not significant after adjusting for spontaneous labor, the Bishop score, and rupture of membranes on admission.

Committee on Fetus and Newborn. Timely maternal management together with notification of the neonatal health care providers will facilitate appropriate evaluation and empiric antibiotic treatment when indicated.

The presence of risk factors of chorioamnionitis, especially membrane rupture, further strengthens the diagnosis. The Centers for Disease Chorioamnionitjs and Prevention and the American Academy of Pediatrics provide guidelines for assessing risk of neonatal infection 7, 35— Labor epidural analgesia and intrapartum maternal hyperthermia. Contrary to most obstetric conditions, chorioamnionitis in a previous pregnancy may not be associated with an increased risk of chorioamnionitis in a subsequent pregnancy [ 20 ].

Common antibiotic choices for treatment of suspected intraamniotic infection are listed in Table 1.

Chorioamnionitis is associated with postpartum maternal infections and potentially devastating fetal complications including premature birth, neonatal sepsis and cerebral palsy. No change in the incidence of ampicillin-resistant, neonatal, early-onset sepsis over 18 years. Active bacterial chorioanmionitis surveillance ABCs: Vaginal Ureaplasma urealyticum colonization: They are commonly isolated from amniotic fluid in the setting of preterm birth or premature membrane rupture with or without clinical chorioamnionitis [ 41 ].

Intrapartum management of intraamniotic infection. FIRS has also been linked to preterm labor culminating in perinatal death Figure 2 and is associated, particularly among preterm neonates, with multi-organ injury, including chronic lung disease, periventricular leucomalacia and cerebral palsy, [ 62 — 64 ] Although FIRS may occur in the setting of non-infectious inflammation, its magnitude tends to be significantly more robust with documented infection [ 61 ] Although chorioqmnionitis controversial, fetal chorioamnionitsi to genital mycoplasmas U.

Intrapartum Management of Intraamniotic Infection – ACOG

A microbiologic and clinical study of placental inflammation at term. Chorioamnionitis and intraamniotic infection. Risk factors for fever in labor. Clindamycin does provide coverage against mycoplasma hominis but none of the 3 standard antibiotics is effective against ureaplasma species which is the most common group associated with infection.

Diagnosis and Management of Clinical Chorioamnionitis

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.

The protective effect of maternal acg antibiotic administration has been demonstrated in recent multivariate risk models of individual infant risk of neonatal sepsis 5, Other tests on amniotic fluid table 2 are limited in their overall predictive abilities for chorioamnionitis although the interleukin 6 and matrix metalloproteinase are more promising because of higher sensitivity and specificity [ 30 — 32 ].


The fetal inflammatory response syndrome. Acute chorioamnionitis and funisitis: Data suggest that women who have vaginal deliveries are less likely to have endometritis and may not require postpartum antibiotics Antibiotic regimens for management of intraamniotic infection.

Diagnosis and Management of Clinical Chorioamnionitis

A strong association between untreated GBS bacteriuria and chorioamnionitis may reflect the high concentration of GBS in the genital tract [ 19 ]. Microbial invasion of the amniotic cavity with Ureaplasma urealyticum is associated with a robust host response in fetal, amniotic, and maternal compartments. This information should not be chroioamnionitis as inclusive of all chorjoamnionitis treatments or methods of care or as a statement of the standard of care.

Antibiotics should be chorioanionitis in the setting of isolated maternal fever unless a source other than intraamniotic infection is identified and documented. Maternal fever even in the absence of documented fetal acidosis is associated with adverse neonatal outcomes, particularly neonatal encephalopathy, though it is unclear to what extent the etiology of the fever rather than the fever itself is causative [ 88 ].

As suggested by the name, clinical chorioamnionitis is diagnosed solely based on clinical signs since access to uncontaminated amniotic fluid or placenta for culture is invasive and usually avoided.
