ABSTRACT
Background: Thrombocytopenia is second most common haematological abnormality in pregnancy after anemia. The aim of this study was to find out the prevalence, causative factor of thrombocytopenia and to observe the obstetrics outcome of pregnancies complicated with thrombocytopenia.Methods: This is prospective study of maternal outcome in pregnancy with thrombocytopenia carried out at tertiary care center from February 2019 to January 2020. Out of 350 antenatal screened women, 25 women who were diagnosed with thrombocytopenia, were included in the study.Results: The incidence of maternal thrombocytopenia in this study was 7.1%. 60% of the women had mild thrombocytopenia while 24% and 16% of women were moderate and severe thrombocytopenic respectively. Amongst 25 thrombocytopenic women 68% had gestational thrombocytopenia, 24% had gestational hypertensive disorder,4% had HELLP syndrome, 4% had immune thrombocytopenic purpura. 60% were delivered vaginally and 40% were delivered by LSCS. The most common indication of LSCS was acute fetal distress (40%) followed by failed induction (30%), breech (10%), and the rest (20%) for other obstetrical indications. The most common indication for induction was pre-eclampsia followed by IUGR, and post-date.Conclusions: In pregnancy with thrombocytopenia, gestational thrombocytopenia is the commonest and benign condition which does not alter the obstetrical management. Still a vigil 4 should be kept on maternal platelet count in antenatal period to prevent unfavorable outcome in serious conditions that may require specific and urgent management (HELLP syndrome, severe pre-eclampsia, ITP).
