Introduction: Gestational thrombocytopenia, a common hematological disorder in pregnancy, poses risks to both maternal and neonatal health. This study aims to evaluate the fetomaternal outcomes in pregnancies complicated by gestational thrombocytopenia compared to those with normal platelet counts. Methods: This prospective cohort study was conducted over 12 months at Jalalabad Ragib-Rabeya Medical college hospital sylhet Bangladesh. It included 100 pregnant women diagnosed with gestational thrombocytopenia (platelet count <150,000/µL after 20 weeks of gestation) and 100 matched controls with normal platelet counts. Maternal data included demographic information, obstetric and medical history, mode of delivery, incidence of pre-eclampsia, postpartum hemorrhage, and need for platelet transfusions. Fetal outcomes assessed were birth weight, Apgar scores, preterm birth rates, NICU admissions, and neonatal thrombocytopenia. Data were analyzed using t-tests for continuous variables and chi-square tests for categorical variables, with multivariate logistic regression to identify predictors of adverse outcomes. Result: The gestational thrombocytopenia group showed higher, though not statistically significant, rates of cesarean delivery (30% vs. 25%, p=0.453), pre-eclampsia (15% vs. 12%, p=0.540), and postpartum hemorrhage (18% vs. 10%, p=0.110). Platelet transfusions were required more frequently in the gestational thrombocytopenia group (8% vs. 2%, p=0.052). Fetal outcomes revealed lower mean birth weight (2950g vs. 3050g, p=0.145), higher preterm birth rates (14% vs. 10%, p=0.371), and more NICU admissions (20% vs. 12%, p=0.132) in the gestational thrombocytopenia group. Notably, neonatal thrombocytopenia was significantly more prevalent in the gestational thrombocytopenia group (10% vs. 2%, p=0.017). Conclusion: Gestational thrombocytopenia is associated with increased risks of certain maternal and neonatal complications. Vigilant monitoring and management are essential to improve outcomes in affected pregnancies. Further research is needed to develop targeted interventions and improve antenatal care practices.
