To this day, haemorrhage, complicating up to 5% of labours, is one of the most common obstetric causes of morbidity and mortality in women [1]. Due to the speed of its development, peripartum haemorrhage can, in a very short time, lead to life-threatening hypovolaemic shock [2, 3]. Excessive blood loss requires comprehensive treatment to maintain peripheral tissue oxygenation, adequate volume of the intravascular compartment and coagulation [1]. In such circumstances there is an indication to transfuse red blood, plasma and platelets. Currently no other equally effective treatment is known. Jehovah's Witness (JW) women are in a high obstetric risk group. British data indicate that in the UK the risk of death related to obstetric complications is 65 times higher in this group than in the general population; in the USA such risk is estimated at 44 times higher [1-5]. Russo et al., describing a case of a JW pregnant multipara after two caesarean sections with placenta praevia invading her urine bladder, found the risk of death to be 130-fold higher than in a patient who would accept blood transfusion [6]. It is estimated that every year 1000 JW die because of blood refusal [4].
