Objective: To determine the postpartum platelet count in preeclampsia, eclampsia and chronic hypertension with superimposed preeclampsia. Method: Prepartum and postpartum platelet counts were investigated; when thrombocytopenia was reported (< 150 000 x mm3), it was monitored every 12 hours until reaching normal values. Setting: Hospital Central "Dr. Urquinaona", Maracaibo - Zulia. Results: Eighty five patients were studied. There were 21 patients with mild preeclampsia, 35 with severe preeclampsia, 10 with eclampsia and 19 with chronic hypertension with superimposed preeclampsia. Twenty one patients presented prepartum thrombocytopenia; at 12, 24, 36 and 48 hours postpartum the levels remained low in 13, 9, 3 and 2 patients respectively, there was no thrombocytopenia at 60 hours. Conclusion: The thrombocytopenia associated with preeclampsia, eclampsia and chronic hypertension with superimposed preeclampsia was normalized at 48 hours postpartum. We recommend platelets counts every 12 hours to follow up its evolution and the prognosis of these patients
