This study assesses the role of abnormal fetal heart rate tracing patterns in patients with thick meconium staining of the amniotic fluid and its association with perinatal outcomes.Methods: Prospective unmatched case-control study on 2 groups of 136 subjects each- cases had thick MSAF and controls had clear liquor with abnormal fetal heart rate tracings on cardiotocography.Results: Gestational age (GA) >40 weeks, was found to have a significant association with MSAF (p value 0.01556 CI 95%).

Premature Rupture of membranes at term (PROM) showed a significant association with MSAF with an OR of 2.25 (95% CI 1.37, 3.7); Post datism had significantly higher odds for being a risk factor for MSAF with an OR (3.194) (CI 95% 1.003-10.165). MSAF was not found to be significantly associated with abnormal trace on CTG. Neonatal morbidity (MAS, birth asphyxia, sepsis, HIE) had statistically higher odds in cases 1.669 (0.884-3.150) as compared to controls.Conclusions: No particular cardio-tocograph pattern can be considered to have a poor prognostic value in the presence of thick MSAF and the decision to deliver and the mode of delivery should be based on the overall assessment and the stage and progress of labor. While management should be individualized, a higher Caesarean section rate in thick MSAF can be justified to ensure a better outcome for the neonate even in the presence of a normal CTG trace.
