Impact of Meconium-Stained Amniotic Fluid on Neonatal Outcome in a Tertiary Hospital

Abstract

Objective The aim of this study was to determine the perinatal outcome of pregnant patients complicated with meconium-stained amniotic fluid (MSAF) compared with clear amniotic fluid. Methodology This prospective cross-sectional study was conducted in the Department of Obstetrics and Gynecology in collaboration with the Department of Pediatrics at Indira Gandhi Institute of Medical Sciences, Patna, India, from September 2016 to January 2018. A total of 200 patients were included in the study after taking their written consent. Out of these 200 patients, 100 patients had MSAF, and the other 100 patients with clear liquor were taken as controls after fulfilling the inclusion and exclusion criteria. These two groups of patients were compared regarding various maternal and neonatal parameters. These parameters were compared and tested statistically for significance. Results Among the 100 patients with MSAF, 20 patients had grade 1 meconium (X), 22 patients had grade 2 meconium (Y), and 58 patients had grade 3 meconium (Z). The majority of patients in the MSAF group were primigravida and more than 25 years of age. In addition, 47% of patients in the MSAF group had some associated high-risk factors and 50% of patients had non-reassuring fetal heart rate patterns, and among these, 39 patients had grade 3 MSAF (X). In the MSAF group, 49% of patients had undergone lower segment cesarean section (LSCS), whereas in the non-MSAF group, it was 37%. Also, 30% of babies in the MSAF group and 13% in the non-MSAF group had neonatal intensive care unit (NICU) admission; 22% of babies in the MSAF group and 12% of babies in the non-MSAF group had an adverse neonatal outcome. Meconium aspiration syndrome was present in 14% of the patients in the MSAF group, and among these, two babies had neonatal death and both had severe birth asphyxia. In the non-MSAF group, there was one neonatal death due to neonatal sepsis. However, after statistically analyzing the neonatal outcome in both the groups, there was no statistical difference between the two groups (p<0.001). Conclusion MSAF is associated with increased frequency of operative delivery, poor neonatal outcomes, and increased NICU admission. Management of labor with MSAF requires appropriate intrapartum care with continuous fetal heart rate monitoring, and this can reduce unnecessary cesarean sections in patients with MSAF.
