Fetal Outcome in MeconiumStained Deliveries

摘要

Objective: To evaluate the foetal outcome in Meconium Stained Amniotic Fluid (MSAF).Material and Methods: This prospective observational study was carried out in the Department of Obstetrics and Gynaecology, North Eastern Indira Gandhi Regional Institute of Health And Medical Sciences, Shillong, India, over a period of eighteen months, from January 2010 to June 2011. A total of 355 pregnant women who had completed more than 37 weeks of gestation, with singleton pregnancies and cephalic presentations were included in this study. One hundred and sixty five cases with MSAF, were thus selected and they were compared with 190 randomly selected controls.Results: Among 165 cases, 27.88 % of the cases had regular visits to the Institute at least 3 times previously, 72.12% cases had no previous visit at all. Primigravidas accounted for a majority of cases and approximately 50% cases had gestational ages of more than 40 weeks Pregnancies complicated with pregnancy induced hypertension had statistically significant higher rates of meconium staining among cases (16.97%), as compared to those among controls (7.89%). 21.81% cases had foetal heart rate abnormalities, as were detected by electronic foetal monitoring and presence of foetal bradycardia was statistically higher in cases compared to that in controls. Casearean section rates were nearly double in cases (49.09%). Neonatal outcome was poor in terms of low Apgar score at birth, birth asphyxia, Meconium Aspiration Syndrome (MAS) and increased neonatal admission among cases as compared to that among controls.Conclusion: Meconium stained amniotic fluid is really worrisome from both, obstetrician?s and paediatrician?s points of view, as it increases the caesarean rates, causes birth asphyxia, MAS and increases neonatal intensive care unit admiss
