A primigravida was induced for PET, the liquor was meconium stained; she was put on oxytocin in-fussion and developed hypertonic uterine action. She then had an amniotic fluid embolism which presented clinically as profound shock, dyspnoea, tachycardia, cyanosis, hypotension and pyrexia. The patient was delivered by vacuum extraction. The picture was further complicated by pulmonary oedema intravascular microcoagulation and anuria. She deteriorated rapidly and died despite treatment with double strength plasma (in the absence of fibrinogen), massive hydrocortiosone therapy, blood transfusion amd sub-total hysterectomy. Post mortem findings in the lungs confirmed amniotic fluid embolism.

Air embolism, diagnosed by clinical therapeutic trial in the Navy hyperbaric chamber, occurred in a woman having labor induced by hypertonic saline for intrauterine fetal death at 25 weeks' gestation. 20 hours after saline administration, and 2 hours after 2 mU/minute diluted oxytocin was started, she had a sudden cardiovascular collapse with cyanosis and dyspnea. She was resuscitated by ventilation by mask and iv fluids. When she regained consciousness she was cortically blind. During treatment by the Navy's protocol, 30 minutes of compression at 6 ATA alternating cycles of 100% oxygen and air after rapid decompression to 2.8 ATA for 5 hours 19 minutes, there was a dramatic improvement in vision. After treatment, she showed left hemianopsia with macular damage. A year later only slight loss of left visual field remained. Air embolism can only be differentiated from amniotic fluid embolism by demonstration of amniotic fluid or fetal components in the maternal central circulation, or a therapeutic trial in a hyperbaric chamber. It is safer to try the pressure chamber immediately.

In a study of 32 patients, there were 29 cases of intra-uterine fetal death and 3 cases of hydatidiform mole. The intravenous administration of either prostaglandin E1, E2 or F2 successfully induced labor in 29 out of the 32 cases. 2 patients delivered following additional intravenous oxytocin and there was 1 failure due to the development of upper limb cyanosis. Side-effects included vomitng, phlebitis, facial flushing, rigors, pyrexia and uterine hypertonus. The method confirms the high success rates reported previously but the incidence of side-effects was disturbing. It is emphasized that prostaglandin E1 was used during this original research trial when prostaglandins were 1st investigated clinically. Prostaglandin E1 has not been made available commerically.

Literature on the etiology, diagnosis, and treatment of missed abortion is reviewed. Missed abortion during the 1st 28 weeks of gestation is defined as retention in the uterus of an abortus. The incidence of missed abortion among spontaneous miscarriages is 2.6-9.4%. Etiology of missed abortion is associated with intrauterine infections, severe abnormalities, inhibition of uterine contraction, or impairment of the hormonal balance. Prolonged retention of an abortus can result in fetal maceration or mummification. Clinical manifestations of missed abortion include absence of fetal heart tone, discharge from the breasts and diminution of their size, general fatigue, fever, and sometimes skin itch. Diagnosis of missed abortion is based upon the results of general and gynecologic examinations. Missed abortion is characterized by cessation of growth of the uterus, decrease in cyanosis of the cervix uteri, decrease in urinary excretion of estriol (up to 0-5 mg/day), drastic decrease in excretion of chorionic gonadotropin, decrease in blood level of placental lactogen, and decrease in pregnadiol excretion. Echographic signs of missed abortion during the 1st trimester include absence of heart activity, absence of fetal movements, and changes in the size of the uterus, amniotic cavity, and embryo. The most frequent complications of missed abortion are uterine hemorrhage, infection, and malignant transformation. Treatment of women with missed abortion consists of administration of abortifacient agents and curettage. The most frequently used abortifacient agents are oxytocin in large dosages, intravenous infusions of prostaglandin e2 (PGE2) or single intraamniotic injection of 15-methyl-PGF2alpha. The women with threatening uterine hemmorrage can be subjected to hysterectomy.
