[Prompt resuscitation by obstetric anesthesiologists saved a parturient with amniotic fluid embolism: a case report].

Amniotic fluid embolism (AFE) is a disorder with a high mortarity rate, because it often causes sudden respiratory failure, circulatory collapse and disseminated intravascular coagulation (DIC). We present a case of AFE in which an obstetric anesthesiologist promptly initiated resuscitation of a parturient and saved her without any sequelae. Her fetus was diagnosed as intrauterine fetal demise on 25th gestational week and vaginal delivery under epidural analgesia was planned. One hundred and five minutes after induction of labor with prostaglandine E1, sudden tetanic convulsion occurred with a loss of consciousness. An obstetric anesthesiologist immediately started to resuscitate her and her consciousness was restored. However, noncoagulable vaginal bleeding followed. As the hemorrhage persisted, AFE was suspected. Anesthesiologists gave effective massive transfusion therapy, and she recovered from coagulopathy. Total blood loss was 5,524 g. This case was diagnosed as AFE with high serum sialyl-Tn antigen and zinc-coproporphyrin. The obstetric anesthesiologists are one of the best groups of physicans for resuscitation because they have skills in managing obstetric emergencies such as AFE. In this case, the crucial points for successful resuscitation were prompt obstetric anesthesiologist involvement and good communications with obstetricians and midwives.
