This review mainly analyses the amniotic fluid embolism (AFE), acute fatty liver of pregnancy (AFLP), HELLP syndrome and severe preeclampsia which may lead most cases of MNM. Finally, summarize the factors and managements associated with maternal near-miss morbidity. INTRODUCTION Amniotic fluid embolism (AFE) Maternal near miss refers to someone who survived a severe Introduction: complication in pregnancy, childbirth, or the postpartum period. catastrophic obstetrics complication occurring during labor Amniotic fluid embolism (AFE) is a With the developing of our society, more and more people are and delivery or immediately postpartum, and is characterized concerned about the maternal near-miss morbidity and mortality. by sudden cardiovascular collapse, respiratory distress, altered measures to decrease the mortality of MNM-most happened They also pay attention to the scientific and effective treatment mental status and disseminated intravascular coagulation (DIC). AFEDiagnosis: is one of the leading causes of maternal death worldwide [1]. cell and other debris of presumed fetal origin may be found, Thisin cases review of amnioticwill focus fluid on the embolism factors, the(AFE), early acute clinical fatty diagnosis liver of In women with AFE, we will find that squamous andpregnancy the management (AFLP), HELLP measures syndrome of MNM. and severe preeclampsia. iseither clinical, at autopsy based oron pulmonary the presence artery of catheter,these elements but is difficult and the to diagnose early.

The manifestations of typical AFE are acute dyspnea which cases of maternal near miss were identified among women who were admitted to Kowloon Hospital between January 1, fibrillation, ventricular tachycardia or seizures, acute confusion 2008 and December 31, 2012. occurred within 10–30 min. Meanwhile, the atypical AFE showed postpartum hemorrhage with DIC as the initial presenting Over the 5-year period of the study, there were 18104 live symptom, and usually occurred after delivery or up to 2 days [2]. births at Kowloon Hospital and 208 cases of potentially life- into three phases.
