ABSTRACT INTRODUCTION: Transfusion is commonly done in clinical indications and complications arising due to Anemia, shock, blood loss, thrombocytopenia due to any cause, ineffective erythropoiesis. Pregnancy is a physiological condition characterized by Anemia, fluid overload, hypercoagulable state, and antifibrinolytic condition, which can cause various reactions that could be anticipated during a blood transfusion. With an aim to understand the effects of transfusions on hematological parameters in pregnancy. The results of whole blood and component transfusion were studied to understand increments and their effects so that rationalized transfusion decisions during pregnancy can be undertaken, considering the physiological changes in pregnancy on hemodynamics are present. METHODOLOGY: A prospective study with 80 pregnant females undergoing blood transfusion was studi ed. Their coagulation and hematological profile were correlated to derive a conclusion for the effect of transfusion of blood and its products. RESULTS: A mean increment of 0.55+0.07 g/dL hemoglobin (Hb) was noted along with a slight increase in RBC count (0.25+0.07 millions/mm3), hematocrit (HCT) (1.9+0.42%), TLC (400+565 cells/mm3). This statistically significant mean increase in hemoglobin, RBC count, and hematocrit was significantly lower than that compared to studies in the west and non-anemic patients. A mean increment of 7.79+1.51 µg/dL (statistically significant) in serum iron was seen. A significant improvement in their coagulation profile was achieved by plasma transfusion (FFP). Clotting time (CT) decreased by a mean value of 196.43+56.69 secs and prothrombin time (PT) by 2.64+0.63 secs (P<0.05). All transfusion reactions in our study were associated with PRBC transfusion, non-hemolytic immunological type, urticarial transfusion reactions ( UTR) more common in multiparous women-0.2% in primigravida to 21.7% and 37.5% in 3rd and 4th parity similar to that observed in other studies. CONCLUSION: Although different researchers have done numerous studies, the physiological profile of pregnant females in India is markedly different in nutritional profile, ethnicity, environmental factors, and background. The availability of tertiary care medical facilities during ANCs is also known to affect pregnancy outcomes and the presentation of patients at term or in labor. The variety of factors affect the baseline hematological status of pregnant females and, hence, post-transfusion hematological factors. These are therefore markedly different from prior published studies. It is concluded that PRBC transfusion in pregnant women causes a lower increase in mean Hb and HCT values than in the west, and ferritin and serum iron are not reliable indicators of Anemia in transfusion. Due to lower increments in all values except platelet s could be the reason for this could be contributed by confounding factors like Anemia, hyperfibrinogenemia, volume overload, and ethnicity.
