Description

Internet-based emergency care system for critically ill pregnant women

technical field

The invention belongs to the field of disease monitoring and nursing, and relates to a monitoring system, in particular to an Internet-based emergency monitoring system for critically ill pregnant women.

Background technique

Maternal death is defined as maternal death caused by various reasons (except accidents) from the beginning of pregnancy to 42 days after delivery. The maternal mortality rate in western developed countries has dropped to less than 1/10,000, while in my country, the maternal mortality rate can reach about 2/10,000 in big cities, 4 to 5/10,000 in advanced rural areas, and 5/10,000 in remote areas. It can reach more than ten thousandths. This shows that the maternal mortality rate in my country is still relatively high, and strengthening maternal health care and management will help reduce maternal mortality.

The four common causes of maternal death are: 1. Postpartum hemorrhage; 2. Pregnancy complicated with heart disease; 3. Placental abruption; 4. Amniotic fluid embolism.

Postpartum hemorrhage refers to the bleeding > 400ml within 2 hours after delivery of the fetus, or > 500ml within 24 hours, ranking first among the causes of maternal death in my country. If a large amount of blood is lost in a short period of time, hemorrhagic shock can occur rapidly, and in severe cases, the life of the puerpera can be endangered. If the shock lasts too long, it can cause ischemic necrosis of the pituitary gland, followed by severe adenohypophysis. Therefore, first aid for postpartum hemorrhage is very important. of. Most patients with postpartum hemorrhage can be predicted. If there are factors that cause bleeding, such as twins, polyhydramnios, too large fetus, multiple deliveries, etc., the uterine muscles will relax, and the postpartum contraction is prone to poor bleeding; another example is the uterus The endometrium is unhealthy, which may be caused by infection, or due to multiple induced abortions, etc., postpartum prone to placental incompleteness and other problems such as bleeding; dystocia or acute labor, surgical midwifery, etc. can often cause birth canal tearing and bleeding; pregnancy-induced hypertension syndrome Syndrome, intrauterine fetal death, early placental dissection, amniotic fluid blockage, etc. can often cause coagulation disorders or pregnant women have blood diseases, etc., may cause massive bleeding due to non-coagulation of blood. Therefore, in case of any of the above situations, bleeding should be prevented as soon as possible.

According to the statistics of maternal deaths in 21 provinces, municipalities and autonomous regions of the country in 1991, pregnancy complicated with heart disease took the second place, second only to postpartum hemorrhage. Rarely suffer from pregnant women. There are two types of heart disease common in pregnant women: rheumatic heart disease and congenital heart disease. Mitral stenosis and regurgitation are the most common cases of rheumatic heart disease in pregnancy. Most patients can survive pregnancy, childbirth and puerperium safely. Common congenital heart disease in pregnancy is atrial septal defect, ventricular septal defect, pulmonary artery stenosis, patent ductus arteriosus and aortic stenosis, etc. These pregnant women can generally survive pregnancy, childbirth and puerperium safely. If the pregnancy is combined with tetralogy of Fallot, pulmonary stenosis and atrial septal defect, it will cause a burden on the heart, and it is generally not suitable for pregnancy. If you are pregnant, you should terminate the pregnancy early. At present, there is also a relatively rare peripartum cardiomyopathy, which mainly refers to the unexplained heart disease that has never had any heart disease before, but occurs in the late pregnancy or postpartum. Although this heart disease is rare, it is difficult to diagnose. , It is more harmful to pregnant women and should be paid enough attention. For the prevention and treatment of pregnancy complicated with heart disease, first of all, the heart examination should be paid attention to during the pre-marital examination. Once heart disease is found, correct guidance should be given on whether pregnancy is possible. If you are pregnant but not suitable for pregnancy, you should have an induced abortion in the first trimester. If the pregnancy continues, prenatal health care should be strengthened, and prenatal care should be started from early pregnancy, and regular inspections should be made according to the doctor's advice, so don't be careless. The focus of the inspection is the prevention of heart failure.

After 20 weeks of gestation or during childbirth, the placenta in the normal position is partially or completely separated from the uterine wall before the fetus is delivered, which is called placental abruption. Placental abruption is a serious complication in the third trimester of pregnancy. It often has an acute onset and rapid progress. If it is not treated in time, it can threaten the life of the mother and fetus. It is more common in multiparous women, and it is easy to recur when pregnant again. If pregnant women experience vaginal bleeding (more or less), abdominal pain, anemia and other symptoms after 20 weeks of pregnancy or during childbirth, they should go to the hospital in time.

Amniotic fluid embolism refers to a syndrome in which amniotic fluid enters the maternal blood circulation during childbirth, causing a series of severe symptoms such as pulmonary embolism, shock, and disseminated intravascular coagulation. It is one of the leading causes of maternal death. Common reasons are multipartum acute labor, placenta previa, placental abruption, uterine rupture, cesarean section, and non-standard application of oxytocin. In order to effectively avoid amniotic fluid embolism, regular prenatal examinations should be done to understand the position of the fetus and placenta, the size of the pelvis of the pregnant woman, the development of the fetus in the uterus, and the health status of the pregnant mother itself, which is of great significance to the smooth delivery of the mother. . If there are abnormalities such as placenta previa, premature rupture of membranes, and premature detachment of placenta, you must go to the hospital to wait for delivery. The doctor will closely observe the changes of the mother and the fetus, and take corresponding measures in time. In the event of an accident, you can also win valuable rescue time.

There are 500,000 maternal deaths every year in the world, equivalent to 1 death per minute, 99% of which are in developing countries, and 90% of these deaths are preventable. China is relatively advanced among developing countries in this regard, and should provide some experience for your reference. Recently, the Jiangsu Provincial Health and Family Planning Commission issued the "13th Five-Year Plan for the Development of Maternal and Child Health Care in Jiangsu Province (2016-2020)" and proposed that during the "13th Five-Year Plan" period, the health rate of maternal and child health service institutions will increase to over 95%. , the maternal and child health care management rate is stable above 95%, the hospital delivery rate is stable above 99%, and the maternal mortality rate, infant mortality rate, and birth defect incidence rate are controlled below 6/100,000, 5‰, and 5‰ respectively , fully completed the tasks of major public health service projects for women and children, and further increased the coverage of the target population of free pre-pregnancy eugenic health checkups. If my country's emergency care system for critically ill pregnant women can be widely implemented in the country, I believe it will achieve good results and receive widespread support from the society.
