We have measured platelet count, bleeding time and thrombelastography (TEG) variables and the correlation between these variables in 49 pregnant patients presenting with pre-eclampsia or eclampsia. Eighteen patients (37%) had a platelet count < or = 150 x 10(9) litre-1 and seven (14%) had a platelet count < or = 100 x 10(9) litre-1. Bleeding time was prolonged > 9.5 min in 13 (27%) patients and the TEG was abnormal in four (8%). The TEG variables, k time and maximum amplitude (MA) had a strong correlation with platelet count (k time-platelet count < or = 150 x 10(9) litre-1, r = -0.68, P = 0.003, platelet count < or = 100 x 10(9) litre-1, r = -0.84, P = 0.02; MA–platelet count < or = 150 x 10(9) litre-1, r = 0.72, P = 0.001, platelet count < or = 100 x 10(9) litre-1, r = 0.78, P = 0.04). There was no correlation between bleeding time and thrombocytopenia (platelet count < or = 150 x 10(9) litre-1, r = -0.18, ns; platelet …
