The mother and child were in a very dangerous condition. An emergency cesarean section was performed and medication was administered to ensure the safety of the mother and child. The patient was treated with surgery (cesarean section) and medication (magnesium sulfate injection + 0.9% sodium chloride injection + ceftriaxone sodium for injection + contraction injection). The fetus was delivered successfully by cesarean section, the blood pressure returned to normal, and the condition was controlled I. Initial consultation The 34-year-old woman had no previous history of hypertension and epilepsy, had two abortions, and had one child with her ex-husband by normal delivery. At the end of February 2021, she started to have dizziness, headache and edema of both lower limbs without abdominal pain and vaginal bleeding, so she did not pay attention to them, but on March 13, she had a sudden seizure at home without any obvious cause, foaming at the mouth, and did not respond to calls for about 1 minute. The husband brought her to our hospital by 120. Blood pressure was measured at 186/116 mmHg, and fetal heart sounds were heard at 110 beats/min. After admission, we immediately completed blood sampling, urine routine, fetal monitoring, fetal ultrasound and other tests, including urine routine urine protein (++++), ultrasound indicates late intrauterine pregnancy, single live fetus, head position, a 3×2cm dark area between the uterine wall and placenta, placental abruption is considered, fetal monitoring indicates no acceleration of fetal heart, fetal heart baseline 100 beats/min. The doctor explained to the mother and her family that the condition of the mother was very serious because of eclampsia convulsions caused by high blood pressure, resulting in fetal distress and placental abruption, and the pregnancy must be terminated by cesarean section immediately. The fetus was delivered with an Apgar score of 4 at 1 minute, and was transferred to the neonatal unit with a score of 7 at 5 minutes after tracheal intubation and positive pressure oxygen administration. Intraoperatively, about 70 ml of blood and clots were seen between the placenta and the uterine wall, and nearly 1/5 of the placenta showed signs of abruption, which was consistent with the ultrasound findings. The operation went smoothly, and the maternal blood pressure decreased spontaneously to 138/86 mmHg after the operation, and magnesium sulfate injection was given for 48 hours as antispasmodic treatment to prevent the occurrence of postpartum eclampsia. At the same time, 0.9% sodium chloride injection plus ceftriaxone sodium for injection was given for anti-inflammatory treatment after the operation, and contraction-promoting uterus injection was given to reduce postpartum bleeding. III. Treatment effect The operation was smooth, and the maternal blood pressure dropped naturally after the operation. Antispasmodic drugs and anti-inflammatory drugs were given, and uterine contraction was promoted by contractin injection to reduce postpartum bleeding. 5 days after the operation, the maternal general condition was good, blood pressure returned to normal, no dizziness, headache, good uterine regeneration, less bleeding, redness of abdominal wound, there is a possibility of poor healing, the mother strongly requested to be discharged, and was discharged with a signature, suggesting outpatient treatment. We are glad that the mother’s symptoms have improved after treatment, but we still need to remind her to pay attention to some matters in her daily life: 1. It is recommended to pay attention to the condition of the abdominal wound, change the medicine regularly at the clinic, pay attention to the clean and dry wound to avoid aggravating the infection; 2. After experiencing eclampsia convulsions and surgical trauma, it is easy to produce negative psychological effects, which may lead to postpartum depression, so family members should give more tolerance and care, reduce blame, and make the mother happy; 4. Encourage breastfeeding after delivery, which is beneficial to the recovery of the uterus, and pay attention to contraception after cesarean delivery to avoid premature sexual life. Eclampsia is the most serious stage of gestational hypertension disease, but it rarely occurs in general, especially in pregnant women who have regular maternity checkups during pregnancy. Fortunately, the doctor gave a timely cesarean section to terminate the pregnancy, so that the mother and child were safe.
