The exact mechanism of such an effect remains unclear, although fetal hyperthermia and associated changes in metabolic rate is hypothesized to potentiate the negative effects of tissue hypoxia. Committee on Fetus and Newborn. chogioamnionitis

Mechanisms choruoamnionitis lung injury and bronchopulmonary dysplasia. A strong association between untreated GBS bacteriuria and chorioamnionitis may reflect the high concentration of GBS in the genital tract [ 19 ].

Treating intrapartum fever with antipyretics may also be helpful in reducing fetal tachycardia thereby avoiding the tendency to perform cesarean for a non-reassuring fetal status. Consequently, depending on the criteria used and maternal characteristics including ethnicity and type of laborthe prevalence of chorioamnionitis based on placental pathology varies widely.

Prolonged duration of initial empirical antibiotic treatment is associated with increased rates of necrotizing enterocolitis and death for extremely low birth weight infants. Term maternal and neonatal complications of acute chorioamnionitis.

Women’s Health Care Physicians. 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 ].


Antipyretics should be administered in addition to antibiotics. In sum, the concept of epidural fever remains controversial and warrants additional studies. It is not intended to substitute for the independent professional judgment of the treating clinician. Timely maternal management together with notification of the neonatal health care providers will facilitate appropriate evaluation and empiric antibiotic treatment when indicated.

Epidural analgesia and uterine function. Open in a separate window. Antibiotics, pediatric dysbiosis, and disease. It is nonetheless important to acknowledge that the overall absolute risk of cerebral palsy remains quite low approximately 2 per 1, live births Cell Host Microbe ; Recognition chorioamnioniits intrapartum intraamniotic infection and implementation of treatment recommendations are essential steps that effectively can minimize morbidity and mortality for women and newborns.

Diagnosis and Management of Clinical Chorioamnionitis

Influence of intrapartum antibiotic prophylaxis for group B streptococcus on gut microbiota in the first month of life. 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.

Single additional dose postpartum therapy for women with chorioamniotis. Term maternal and neonatal complications of acute chorioamnionitis. In term and near-term infants it is associated with a 4-fold increase in the frequency of cerebral palsy [ 76 — 77 ]. Andrews b Charles E. Contrary to most obstetric conditions, chorioamnionitis in a previous pregnancy may not be associated with an increased risk of chorioamnionitis chorioamnionifis a subsequent pregnancy [ 20 ].


Time -to-delivery after institution chorioamnionitiis antibiotic therapy has been shown to not affect morbidities; therefore cesarean section to expedite delivery is not indicated for chorioamnionitis unless there are other obstetric indications [ 125378 ]. Intrapartum management of intraamniotic infection.

Intraamniotic infection can be associated with acute neonatal morbidity, including neonatal pneumonia, meningitis, sepsis, and death, as well as long-term infant complications such as bronchopulmonary dysplasia chorioanmionitis cerebral palsy.

Confirmed intraamniotic infection is based on a positive amniotic fluid test result gram stain, glucose level, or culture results consistent with infection or placental pathology demonstrating histologic evidence of placental infection or inflammation. No change in the incidence of ampicillin-resistant, neonatal, early-onset sepsis over 18 years. Recent data on the development of the neonatal microbiome and the role of early antibiotic exposures suggest that antibiotic therapy may not be entirely benign 39— American College of Obstetricians chorioamniontis Gynecologists.

Supportive measures include the use of antipyretics acetaminophen.
