Abstract:

Objective: Thrombocytopenia, expressed as platelet counts lower than 150 × 109 /L, is a common hematological anomaly seen in 6.6% of the pregnancies. Incidental thrombocytopenia of the pregnancy, commonly referred to as gestational thrombocytopenia, accounts for 70%–80% of cases. This study aimed to elucidate the effect of gestational thrombocytopenia on negative fetal and maternal results in low-risk pregnancies. Method: The patients were divided into two groups. The control group (n = 240) consisted of healthy pregnant women with normal platelet count, and the study group (n = 80) consisted of pregnant women with gestational thrombocytopenia. Results: Maternal age, pre-pregnancy body mass indexes, parity, and previous cesarean history rates were similar in both groups. Gestational age during delivery, fetal weight, delivery induction, amniotic fluid stained with meconium, hyperbilirubinemia, admission to neonatal intensive care unit, transient tachypnea of the newborn, respiratory distress syndrome, hypoxic–ischemic encephalopathy, necrotizing enterocolitis, intraventricular hemorrhage, and 5-min Apgar scores of <7 were not different between the groups (P = 0.056, P = 0.233, P = 0.582, P = 0.798, P = 0.711, P = 0.859, P = 0.634, P = 1, P = 1,P = 1, P = 1,and P = 1, respectively). Spontaneous vaginal delivery, necessity for emergency cesarean delivery, postpartum hemorrhage, abnormal hemorrhage during cesarean, necessity for blood transfusion, and postpartum hysterectomy rates did not differ between the groups (P = 0.530, P = 0.752, P<0.001, P<0.001, P = 0.758, P = 1, P = 1,and P = 1, respectively). Despite being within normal limits, discharge time after C/S and spontaneous vaginal delivery was longer in the gestational thrombocytopenia group than in the control group. Conclusions: The results of the study showed that gestational thrombocytopenia did not pose a risk for both the mother and the fetus in low-risk pregnancies.
