Abstract

There are no typical clinical signs in silent chorioamnionitis. It is associated with adverse maternal and neonatal outcome and poor progression of labour. Subclinical chorioamnionitis is also more common in preterm gestations than term gestation and vaginal deliveries than caesarean sections. Descriptive cross-sectional study conducted in Castle Street Hospital for women. Term singleton pregnant mothers were included and preterm labour was excluded. Sample consisted of 154 participants. Antepartum and post-partum surveillances were conducted. amniotic fluid cultures with ABST patterns, perinatal neonatal and maternal outcomes were selected as outcome variables. Data was analysed by using SPSS version 25.0. According to the study mean age of the participants was 29.37 years (SD=5.30years). and the majority represented the 26-36 years age group. Half of the study sample consisted of primigravidae mothers. Occurrence of silent chorioamnionitis was significantly higher among primigravidae (OR=4.056:95%CI=1.270-12.952). Duration of labour exceeding more than 12 hours and performing multiple digital vaginal examinations (OR=3.929:95%CI=1.007-15.328) were identified as significant risk factors for silent chorioamnionitis. Maternal pyrexia (OR=21.000:95%CI=5.316-82.961) and surgical site infections were significantly associated with silent chorioamnionitis (OR=12.667:95%CI=2.570- 62.427). Newborns who were admitted to SCBU due to early neonatal sepsis (OR=16.875:95%CI=1.448-196.68) and who were unable to achieve an APGAR score of 7 at the 5 th minute of their life (OR=4.571:95%CI=1.220-17.129) were significantly associated with maternal silent chorioamnionitis. According to the culture & ABST findings, Staphylococcus aureus
