Prevalence of gestational thrombocytopenia and its effect on maternal and fetal outcome

Abstract

BACKGROUND: Gestational thrombocytopenia (GT) is considered as the most common cause of thrombocytopenia in pregnancy and accounts for about 75% of cases.OBJECTIVES: The objectives of the study are (1) to estimate the prevalence of GT among antenatal patients at Vardhman Mahavir Medical College (VMMC) and Safdarjung Hospital in New Delhi, India, and (2) to study the fetomaternal outcome in mild, moderate, and severe GT.MATERIALS AND METHODS: This is a prospective observational study done in the Department of Obstetrics and Gynaecology, VMMC and Safdarjung hospital in New Delhi, India, for a period of 6 months. All antenatal women underwent complete hemogram with manual platelet count in the third trimester. Those with platelet count 150 × 109/L were included and divided into three groups on the basis of platelet count. Maternal and fetal outcome was observed. Cord blood was sent for neonatal platelet count. Follow-up was done in these cases till 6 weeks postpartum.RESULTS: The prevalence of GT was 12.82%. Fetomaternal outcome was favorable. A total of five (2.5%) patients suffered from abruption. Postpartum hemorrhage was present in about 7 cases (3.5%). Blood transfusion including platelet transfusion was needed in around 13 cases (6.5%). There was no maternal mortality. Only 6 (3%) neonates were having thrombocytopenia (platelet count < 150 × 109/L) regardless of degree of maternal thrombocytopenia. Twenty-six (13%) neonates were admitted in nursery for monitoring; among these, 11 (5.5%) neonates' ventilation was needed. There was no neonatal death.CONCLUSION: Better fetomaternal outcome is seen in GT, so a vigilant and careful monitoring can prevent any adverse event.
