Abstract
Thrombocytopenia is an associated phenomenon of Pregnancy induced hypertension (PIH). But the accurate count of platelets either by manual, (direct or indirect methods) or by automated cell counters is not feasible for all patients at all hospitals. Therefore we have adopted the method of platelet estimation, not platelet count as an alternate procedure to estimate the degree of thrombocytopenia in patients with PIH cases. We included 30 normal pregnant women and 90 pregnant women with varying degree of PIH. Blood platelets were estimated by an accepted manual method. Platelet numbers were found to be 2.38 lacs/mm3 +/- 0.33 in control group, 2.23 lacs/mm3 +/- 0.19 in mild PIH, 1.82 lakhs/mm3 +/- 0.45 in pre eclampsia and 1.21 lacs/mm3 +/- 0.49 in eclampsia. This indicated that there is an inverse relationship between the severity of PIH and platelet numbers. So this method of platelet estimation is useful as a rapid method of assessment in PIH. This method is not only rapid and cheap but can be done even in rural hospital settings.
