KEEP EXPLORING
Amniotic fluid embolism remains an enigmatic and often lethal condition. The pathophysiology is complex, however, from a clinical standpoint. Right or, more commonly, left heart failure is the dominant physiologic aberration. Disseminated intravascular coagulation is often present. The detection of squamous cells in the central circulation of living patients can no longer be considered pathognomonic for this condition.
Embolic phenomena in pregnancy demand rapid investigation and treatment. Regardless, some patients will not survive due to the enormity of the insult. Optimally, such patients should be treated in tertiary care centers, but this is not always possible.
Although both the Japanese maternal mortality rate (MMR) and the perinatal mortality rate (PMR) have decreased remarkably in recent decades, the former is still high compared with other advanced countries. A statistical analysis on the relationship between the MMR and the PMR was performed to investigate this discrepancy. During the period of study, both rates fell by over 50 percent. There were definite statistical differences among the PMR for each prefecture but almost none among the MMR. The prefectures with high PMR remained generally high in the PMR and the prefectures with low PMR also remained low in the MMR. There was no significant correlation between the PMR and the MMR. Both maternal and perinatal deaths due to common causes decreased in number, and there were few regional differences concerning effective measures against them. The leading causes of maternal death which are irrelevant to perinatal death are emboli, bleeding, and some other rare medical complications. Emphasis should therefore be laid upon the early diagnosis and treatment of amniotic fluid embolism apart from measures against haemorrhage. Countermeasures for rare complications are also of great importance.
