[Successful resuscitation in a life-threatening obstetric hemorrhagic patient with hematocrit 3%: a case report].

We report a postpartum woman who suffered from obstetric bleeding after caesarean section. Her lowest hematocrit was 3% when a large amount of blood was lost. "Guidelines for management of critical bleeding in obstetrics" published by the Japanese Society of Anesthesiologists and four related academic societies was helpful for the resuscitation of the parturient. A systematic approach was effective for the care of women with major obstetric hemorrhage.
