Abstract: A 41-year-old woman in advanced maternal age faced with a second child delivery presented to the hospital with redness, irregular lower abdominal distension and gradually strengthening contractions. Because she was a transitional woman, a vaginal trial of labor was requested. However, due to her age and the fact that she was unable to sleep at night due to the strengthening of contractions, she was too tired and had weak primary contractions. She was given sedatives to promote sleep and recover strength, plus pethidine hydrochloride injection, carboprost aminotriol injection, and blood production combination. The woman reported that she had one abortion and one normal delivery, and the process was smooth. Her last menstrual period was on August 14, 2021, and her menopause was 7 weeks before the hospital ultrasound indicated early intrauterine pregnancy, and her expected delivery date was May 21, 2022. She had her first pregnancy in 13 weeks and regular checkups in our clinic. She had amniocentesis in 19 weeks and the results showed no significant chromosomal abnormalities. The systemic ultrasound and glucose tolerance test did not show any significant abnormality. On May 14, she began to have irregular lower abdominal distension after the onset of redness, followed by gradually strengthening contractions, and then went to the hospital. After sterilization, a gynecologic examination was performed, and the cervical canal was 80% regressed and the uterine opening was 1 cm. The diagnosis was “1. 3 weeks of pregnancy and 1. 39 weeks of pregnancy with live birth; 2. Advanced maternal age.” She was admitted to hospital. After admission, we completed blood sampling, fetal ultrasound and other examinations, and evaluated the maternal birth canal and fetal size, etc. There were no obvious abnormalities, and although the mother was advanced in age, she was a menstrual woman, and she requested a vaginal trial of labor. Although she had regular contractions at night, she did not deliver at night. In the early morning of the next day, the contractions did not strengthen, the vaginal examination showed that the cervical canal was receding, the opening of the uterus was 2 cm, and the fetal heartbeat was normal, but the mother could not fall asleep and felt tired. After the mother fell asleep for about 2 hours, the vaginal examination showed that the opening of the uterus was 2.5cm, the fetal head was -2, the contractions were 15-20s/3-4min, the uterine pressure was 50-60, the observation was given for 1 hour but there was no improvement, the primary contraction weakness was considered, after giving the intravenous injection of contractin to strengthen the contraction, the contraction was obviously strengthened, 20-30s/2-3min, the uterine pressure was 80mmHg, the labor progressed smoothly. The labor progressed smoothly, and a live baby was delivered on the same day. The woman was very fatigued after delivery. After delivery, she had weak uterine contractions, the uterus was soft like a pouch, and there was a lot of vaginal bleeding, so she was immediately given massage to the uterus, and given uterine contraction treatment with contractin injection and carboprost aminotriol injection. The woman woke up a few hours later and was clear and did not complain of other uncomfortable symptoms. 4 days after delivery, the woman’s vital signs were stable, the perineal area recovered well, no bleeding occurred, no concomitant infection, and the malignant dew was not excessive. After regular blood supplementation with oral medication, the maternal anemia was corrected, and no pathology was found in the newborn after birth, and respiration, heart rate, pulse rate and blood pressure were all in the normal range. The picture shows the diagnosis certificate of maternal discharge: IV. The mother should be instructed to eat more blood-supplementing foods after discharge, such as pig liver, pig red, spinach, black fungus, etc.; due to the physical exertion of the mother’s advanced delivery, her body is generally weak, so she must ensure sufficient sleep after delivery, minimize staying up late to breastfeed, and her family should help share the work of taking care of the newborn; in addition, the pelvic floor tissue is easily damaged after delivery in advanced mothers, so the pelvic floor function should be assessed well after delivery In addition, the pelvic floor function should be assessed after delivery, and individualized rehabilitation treatment programs should be developed, such as rectus abdominis repair and pelvic floor muscle repair. V. Personal insight Due to the relaxation of the two-child and three-child policy in recent years, there are a lot of advanced maternal age. In this case, the overall physical quality of advanced maternal age is not as good as that of young women, so primary contraction weakness is likely to occur after delivery. When primary contraction weakness and postpartum uterine contraction weakness leading to postpartum bleeding occur, both contractions should be strengthened in time to reach effective treatment.
