Abstract: The patient was 33 years old and pregnant for the first time. She came to the hospital in the last 1 day feeling decreased fetal movement without abdominal pain and vaginal bleeding. After the examination, the fetal cord was found to be wrapped around the neck for 3 weeks and the fetal heart rate could be as low as 110 beats per minute. Combined with the fetal heart monitoring and ultrasound results, the initial diagnosis was intrauterine hypoxia. Because of timely detection and surgery, the newborn was born with good scores and was discharged with the patient on the 4th postoperative day. [Basic information] Female, 33 years old [Disease type] Fetal intrauterine hypoxia [Attending hospital] Huangshi Central Hospital [Attending time] March 2022 [Treatment plan] Emergency cesarean section [Treatment cycle] Hospitalization for 4 days, the patient was reviewed 42 days after discharge, and the newborn was reviewed 3 days after discharge [Treatment result] The newborn was born with good scores, and was discharged with the mother successfully I. Initial interview In the afternoon. The patient was accompanied by her family to our hospital and registered for emergency obstetrics service. After examination and ultrasound, the fetus was found to be in breech position with the umbilical cord wrapped around the neck for 3 weeks. The patient was considered to be suffering from intrauterine hypoxia, so the patient was recommended to be hospitalized. II. Treatment After admission, the patient was immediately given relevant examinations, i.e. physical examination, blood routine, liver and kidney function, coagulation function, pre-transfusion examination, electrocardiogram and other examinations, and preoperative preparations such as skin preparation and urethral catheterization were carried out at the same time. At the same time, we communicated with the patient and her family about the patient’s condition and informed them that the umbilical cord was currently wrapped around the neck for 3 weeks and that intrauterine hypoxia was considered a possibility, and that we recommended emergency cesarean section in view of the patient’s gestational age, fetal position and fetal heart condition. After 4 days of postoperative monitoring of the newborn, there were no significant abnormalities in feeding, jaundice, oxygen saturation, urination and defecation, and mental status. The patient was discharged on the 4th postoperative day. The patient was instructed to observe the newborn’s jaundice, breastfeeding, mental reaction and maternal vaginal bleeding at home after discharge, and to retest the jaundice at the hospital 3 days after discharge. The patient was found to have decreased fetal movement, and the problem of intrauterine hypoxia was detected in time. After an aggressive cesarean section, the duration of intrauterine hypoxia was reduced, which led to a significant improvement in the outcome of the fetus after birth, and the postnatal score was the same as that of a normal-born newborn. After 4 days of observation, no discomfort was observed, so the patient was discharged from the hospital. 14 days after discharge, the patient returned to the hospital for re-examination, and no abnormal neonatal symptoms were found. 42 days later, the patient was examined and found to be recovering well with no other discomfort. Although no danger or other complications occurred for the newborn and the mother, attention should be paid to observe whether the newborn has jaundice, poor spirit and poor appetite in daily life. After discharge from the hospital, the patient should pay attention to keep warm, avoid getting cold, walk appropriately, but avoid heavy physical labor, pay attention to a light diet, avoid spicy and stimulating food, keep regular rest and rest, avoid staying up late, avoid bathing and sexual intercourse within 3 months, and pay attention to good contraceptive measures within 1 year. V. Personal insight 1. Intrauterine hypoxia is the main cause of neonatal asphyxia, cerebral palsy and mental retardation. Therefore, all pregnant women should have regular obstetric checkups, and for patients with high risk factors of intrauterine hypoxia, they should increase the frequency of obstetric checkups under the guidance of doctors to detect the problems in time; 2. The current medical conditions do not allow 24-hour fetal heart monitoring and ultrasound monitoring to determine the intrauterine safety and danger of the fetus. Therefore, it is very important to count the fetal movements after 28 weeks of pregnancy, just like this patient, who fully cooperated with the doctor to count the fetal movements at home and seek medical consultation in time when problems were found, so that the process of rescue and treatment is more efficient and the time of fetal hypoxia in utero is greatly shortened, so that both mother and child can have a good outcome.
