Introduction:Blood transfusion practices is recognized as one of the essential component of comprehensive obstetric emergency care. It aids in reducing the maternal morbidity and mortality and also in promoting a healthier birthing experience for the expectant mother. In countries like India, efforts should be made to ensure early and easy availability of blood and blood products so as to decrease the incidence of maternal mortality.Aim: To describe the blood transfusion pattern in obstetric emergencies andmaternal outcome. To assess the underlying obstetric risk factorswhich necessitate blood transfusion and to assess the ratio of the components used inobstetric emergencies.Methodology:This observational study was conducted for one year on 254 obstetric in-patients who were received in a state of emergency and who received a total of 2171 blood and blood products transfusion to alleviateimminent danger. The data collected were analysed for the red cell usage according to their diagnosis. Blood utilization indices calculated and their role in the reduction of maternal mortality and morbidity.Results:In this study, obstetric emergencies contributed to 26.1% of all transfusions. Most of the cases were in the 25-30years31.8% age group and were multigravida61.7%. The most commonly encountered were Anterpartum Haemorrhage-34.2% cases,Hypertensive disorders-20.4%, Post-partum Haemorrhage-17.7% and ectopic pregnancy-17.5%. Caesarean section was done in 49.6% of cases.The ratio of the components used were PRBC 30.7%, Platelets 18%, Fresh frozen plasma 41.9% and Cryoprecipitate 9.3%. a meagre 1% had transfusion reactions. The maternal mortality rate in the study is 12.9% and ratio is 259/1,00,000. The transfusion indices calculated are C/T ratio 1.01%T 95.6% and TI 1.8.Conclusion:The early and adequate use of blood and blood products shows significant decline in maternal morbidity and mortality. This important Millenium Development Goalscan be attained with judicious use.The transfusion rate in the current study is 3.3: 1.9 : 4.2 : 1.
