Objective: To describe clinical and laboratory characteristics of term deliveries complicated by chorioamnionitis, and to assess their association with adverse neonatal outcomes. Design: Cross-sectional cohort study Setting: The study is based on data from the Swedish Pregnancy Register, enriched with clinical data extracted from medical charts. Population and Sample: A random sample of 500 term singleton deliveries in Stockholm County with registered diagnosis of chorioamnionitis in the Swedish Pregnancy Register between 2014 and 2020. Methods: Logistic regression was used to estimate odds ratios (OR) as a measurement of the association between clinical and laboratory characteristics and neonatal complications Main Outcome Measures: Neonatal infection and asphyxia-related complications. Results: Maternal fever, maternal and fetal tachycardia, and elevated inflammatory laboratory markers were frequent signs of chorioamnionitis. The prevalence of neonatal infection and asphyxia-related complications was 10 and 22%, respectively. First leukocyte count in the second tertile (OR 2.14 [95% CI 1.02-4.49]), maximum CRP level in the third tertile (OR 4.01 [95% Cl 1.66-9.68]), and positive cervical culture (OR 2.22 [95% Cl 1.10-4.48]) were associated with an increased risk of neonatal infection. Maximum level of CRP in the third tertile (OR 1.93 [95% Cl 1.09-3.41]), and fetal tachycardia (OR 1.63 [95% Cl 1.01-2.65]) were associated with increased risk of asphyxia-related complications. Conclusions: In addition to maternal intrapartum fever, maternal and fetal tachycardia, and elevated inflammatory laboratory markers were common signs of chorioamnionitis. Elevated inflammatory laboratory markers were associated with both neonatal infection and asphyxia-related complications, and fetal tachycardia was associated asphyxia-related complications.
