Recently, there has been a lot of media coverage about amniotic fluid embolism, but from the anesthesiologist’s point of view, I think it is better to misdiagnose amniotic fluid embolism than to mistreat it. If amniotic fluid embolism is considered in the first instance, the patient should be treated immediately with anti-allergy (dexamethasone or hydrocortisone sodium succinate sedation) and high-frequency oxygen administration. This is the most important treatment. Even if it is misdiagnosed, giving this measure to a normal person will not cause any significant harm to the patient. This is nothing compared to the delay in resuscitation. Amniotic fluid embolism can occur before, during or after delivery. My personal summary is that patients with amniotic fluid embolism generally have three major symptom groups: the first category is dyspnea syndrome: patients show shortness of breath, panic, chest tightness, cyanosis and dyspnea after a loud cry (or shout), most of them occur before delivery or before delivery; the second category is syndrome characterized by drop in blood pressure: patients show unexplained and unexplained drop in blood pressure, pale face, generalized The third category mostly occurs after delivery and presents with unexplained persistent vaginal bleeding and non-coagulation of blood; in short, the manifestation of unexplained diffuse intravascular coagulation. The symptoms of shock in this category often do not correspond to the amount of bleeding the patient has. Since there are four major causes of postpartum hemorrhage, such as weak postpartum uterine contractions, soft birth canal injury, retained placenta, and systemic hematologic disorders, these factors must be excluded before clinical diagnosis can be made. Therefore, these patients are most likely to be neglected and delayed in diagnosis. These symptoms cross over and end up in one stage: postpartum hemorrhage and diffuse intravascular coagulation. By postpartum hemorrhage, it is defined as bleeding of more than 500mL within 24 hours after delivery in women with vaginal delivery, while in patients with cesarean delivery, it needs to be more than 1000mL to be diagnosed as postpartum hemorrhage. Personally, I understand that if the patient is not managed until this stage, and if the condition is not controlled at an early stage and timely interventions are not made before pathological changes in the blood coagulation system occur, subsequent treatment will be very challenging. The first characteristic of amniotic fluid embolism is its unpredictable nature. All patients are normal during the prenatal examination, which is the main reason for all family members to have disputes with the medical unit after such unfortunate events, and is also an unbeatable way for media reporters to attract attention. The second characteristic of amniotic fluid embolism is that the condition is very aggressive. Nearly 1/3 of patients die in only 30 minutes from the onset of the disease. Such a quick death process makes so many people lose the chance to be rescued, and also makes all the family members incomprehensible, including our doctors of course. So to give the people the so-called right to informed choice for all diseases is actually putting the patients at risk. Because the early diagnosis of this disease is so uncertain, and the condition is so dangerous and fast, where do medical personnel have so much time to talk to you in the process of resuscitation? The third characteristic of amniotic fluid embolism is the high mortality rate. Most reports are 60%, but the highest report is 90%. Because of the high mortality rate, some deaths due to apparent postpartum hemorrhage are sometimes treated as a box by some hospitals.
