It’s hard to carry a baby in October and give birth once, but it’s a critical moment before the delivery, so if you are not careful, you will lose everything. Therefore, it is necessary for mothers-to-be to know what circumstances must immediately go to the hospital? 1, premature rupture of fetal membranes occurs before labor, called premature rupture of fetal membranes. At this time, labor has not yet started, the pregnant woman did not feel the regular lower abdominal pain or only a slight pain, gestational weeks <37 weeks, called premature rupture of membranes, especially between 28 to 35 weeks of pregnancy, premature rupture of membranes, very troublesome, the doctor needs to ensure that the pregnant woman does not infect and fetal lungs as mature as possible, risk "kill a blood road It is very troublesome and requires the physician to take the risk of "killing" the fetus between ensuring that the pregnancy is not infected and that the fetal lungs are as mature as possible. One to two weeks before delivery, the head of the child is officially in the pelvis, at which time the symptoms of dyspnea that plague pregnant women are significantly relieved due to the fall of the diaphragm, while vaginal discharge increases, but the amount is not very large, and the area of the internal reservoir invaded by wetness is not large; pregnant women with heavy vaginitis or cervicitis will also have a significant increase in vaginal discharge, which can be accompanied by odor or vulvar itching, and the diagnosis can be made clearly through the belt routine; very few pregnant women have tension incontinence The most common one is premature rupture of fetal membranes, mostly seen in pregnant women with fetal malposition, abnormal cephalopelvic relationship or amniotic membrane infection, therefore, premature water breakage is a sign of obstructed labor and infection. In addition, if there is more amniotic fluid, longer umbilical cord, smaller fetus, twin pregnancies, breech position and previa, premature rupture of membranes may also cause cord prolapse leading to fetal death in the uterus. The sudden decrease in intrauterine pressure at the time of water breakage may cause the placenta to abscond from the uterine wall, which is called placental abruption and poses a threat to the safety of the mother and the baby and is a more serious complication for the mother. Sometimes the location of the rupture of the fetal membranes is higher called high water rupture, amniotic fluid outflow sometimes more and sometimes less, not easy to attract the attention of pregnant women, the threat to the mother and child is greater. 2, fetal movement is reduced fetal movement is the only indicator that pregnant women can make a difference in the monitoring of their babies and is of great significance. When the fetus is in a state of chronic hypoxia in the womb, the first thing that shows up is a decrease in the number of fetal movements. The fetus may suffer from chronic hypoxia due to placental abruption, umbilical cord factors (thin, knotted, twisted, love pressure, winding), low placental function (seen in hypertensive disorders of pregnancy, overdue pregnancy, intrahepatic cholestasis during pregnancy, placental aging), and intrauterine growth restriction. The normal number of fetal movements is 3 to 5 times per hour and more than 20 times per 12 hours. If the number of fetal movements slows down significantly and does not move a few times a day, you should go to the hospital for fetal heart monitoring and ultrasound if necessary, because ultrasound has S/D (also called umbilical artery flow ratio, which is the ratio of fetal umbilical artery systolic pressure to diastolic pressure), placenta grading, how much amniotic fluid and whether it is cloudy, these information can be used together with These data can be used together with decreased fetal movement to determine the true nature of hypoxia and its possible causes. If chronic intrauterine hypoxia does exist and is not relieved, the fetal heart rate will suddenly disappear about 24 hours after the fetal movement disappears. The importance of observing fetal movement is evident. 3. Vaginal bleeding Vaginal bleeding may be a mere sign of labour, but it is necessary to exclude placenta praevia, placenta abruptio, uterine rupture, rupture of blood vessels of placenta praevia, rupture of blood sinus at the edge of placenta, cervical cancer and other diseases. Placenta praevia is mostly manifested by painless vaginal bleeding and can be clearly diagnosed by ultrasound; placenta abruptio is mostly seen in hypertensive disorders of pregnancy, but also in abdominal trauma and after sexual intercourse, and can be clearly diagnosed by combining medical history, bloody amniotic fluid, ultrasound and lower abdominal pain; uterine rupture is mostly seen in patients with scarred uterus, especially in patients with large fetus, excessive contractions (abuse of contractions and prostaglandin), multiple deliveries, previous Ultrasound examination can often provide valuable clues in women with poorly healed cesarean incisions; sail-shaped placenta is often seen in twin or multiple pregnancies, and ultrasound examination can assist in the determination of the condition. 4, lower abdominal pain There are several possibilities for pregnant women with lower abdominal pain: (1) labor is imminent: there is a simple way to identify whether the uterine contractions before labor are really imminent, which is to see whether the degree of pain in the lower abdomen has a painful posture (bending back) and painful expressions (grimacing and frowning), if the contractions are very regular, 5 to 10 minutes once, with painful posture and painful expressions and progressive strengthening is the imminent labor. (2) placental abruption: in addition to lower abdominal pain, there is also abdominal muscle tension, uterine tension, and still no tenderness between contractions, ultrasound can often assist in the diagnosis; (3) uterine rupture: there is often fixed pressure pain in the lower abdomen, and at the moment of complete uterine rupture, the mother often feels severe abdominal pain in the form of tearing, followed by the disappearance of uterine contractions and pain relief. The pain is relieved, but as blood, amniotic fluid and fetus enter the abdominal cavity, there are soon symptoms of peritoneal irritation, full abdominal pain, accelerated and weak pulse, shortness of breath and decreased blood pressure. In cephalic obstructive obstructed labor, the uterus develops pathological retraction ring, the abdominal wall is shaped like a hrusk, contractions are often accompanied by howling of the mother uncontrollably due to severe pain, and hematuria may be present during catheterization, which is a sign of a precursor rupture of the uterus. It is important to note that rupture of the scarred uterus can occur without contractions and is called spontaneous rupture. (4) Surgical emergency abdomen: lower abdominal pain should be differentiated from pregnancy combined with orchitis and ovarian tumor torsion. 5, headache and blurred eyes For pregnant women, headache and blurred eyes are the most frequent indication of pre-eclampsia. Pre-eclampsia is a kind of severe gestational hypertension disease, and its typical clinical manifestations are hypertension, swelling, proteinuria. When there is self-consciousness such as headache and blurred eyes, it is not far from convulsion (also called eclampsia attack), and the complications of this disease are mainly placental abruption, fetal death in utero, cerebral hemorrhage, heart failure, kidney failure, DIC (diffuse intravascular coagulation), and postpartum hemorrhage. It is one of the four major causes of death in obstetrics in China, second only to postpartum hemorrhage as a life-threatening killer. The "ten critical conditions" of maternity are: premature rupture of membranes; umbilical cord prolapse; placenta abruptio; placenta praevia; fetal distress; eclampsia; amniotic fluid embolism; uterine rupture; cephalic obstructed labor; and postpartum hemorrhage. If the above five conditions are grasped, the "ten critical situations" will be under control. Therefore, once the aforementioned five situations occur, the mother must rush to the hospital as soon as possible, before the clinicians do not come to a conclusion, it is best to temporarily fasting water, so as to avoid the need for surgery left anesthesia unsafe hidden.
