Abstract

Objective: Meconium
stained amniotic fluid is a frequently encountered situation, it can really
disturb an obstetrician, as it increases the rates of neonatal morbidity and
mortality and it is difficult to prevent meconium passage in utero. Noninvasive
tests are needed to predict the meconium staining of the amnion fluid without
making amniotomy or making a fetal invasive procedure. Non stress test is a
commonly used method to determine the status of intrapartum fetal wellbeing.
The purpose of this study was to predict fetal meconium release during labor by
examining the fetal heart rate traces without performing an amniotomy
procedure.

Materials and Methods: A total
of 280 patients who have been diagnosed with active labor were included in the
study. 140 of them demonstrated meconium stained fluid and 140 of them clear
amniotic fluid. The patients’ labor courses have been watched and non-stress
test results have been recorded besides obstetric outcomes.

Results: Non-stress
tests performed before amniotomy; 52 (37.1%) of the non-stress tests in the
meconium group were non-reactivated, whereas in the control group this count
was 19 (13.5%) before amniotomy. When we accepted the deceleration entity as
fetal distress; fetal distress was seen in 62(44.3%) of the patients in the
meconium group and in 21(15.1%) of the patients in the control group.

Conclusion: In the
presence of non-reactive non stress test pattern; we should be suspicious of
meconium-stained amniotic fluid. In this case, caution should be taken in terms
of fetal distress.
