Providing the most needed patient with the proper blood products in the right quantity at the right time allows us to close the gap between blood supply and demand. Effectiveness, safety, and sufficiency can be achieved by avoiding nonessential transfusion. A patient who receives whole blood transfusion may not necessarily need all of its components, but many recipients who need a particular component would benefit from its use by component preparations because, as we all know, blood is constantly in limited supply. The infections and transfusion-related risks of whole blood transfusion can be minimized when a patient just receives the necessary component. Finding the best transfusion perspective for whole blood versus blood component use is our study's main goal. Method: Cross-sectional study is the type of study. The investigation took place over a period of 18 months, from December 2017 to May 2019, at the Obstetrics and Gynaecology Unit of the Southern Railway Headquarters Hospital in Ayanavaram, Chennai. All the women who are admitted for obstetrics services are included in the research region. Results: Few patients in the study have undergone more than one type of blood component transfusion, according to their criteria. There were transfusions of 63.15% packed RBCs, 47.36% whole blood, 14.03% random donor platelets, and 10.52% FFP plasma. Conclusion: Post-partum hemorrhage (PPH) and Anemia during pregnancy were discovered to be the frequent indications for whole blood and packed red blood cell (PRBC) transfusion. Gestational thrombocytopenia and medical conditions complicating pregnancy were the two most frequent causes for platelet concentrate transfusion. Conditions like obstetric hysterectomy, ruptured tubal ectopic, APH, hypertensive disease of pregnancy, and disseminated intravascular coagulopathy (DIC) were evenly distributed indications among the study subjects who received transfusions of fresh frozen plasma (FFP).
