What are Some Signs of Preterm Labor?
Preterm birth refers to those who give birth between 28 weeks and less than 37 weeks of pregnancy. Newborn babies born at this time are called premature babies, weighing 1000 to 2499g. Premature birth in China accounts for 5% to 15% of total births. About 15% of premature babies die during the neonatal period. In recent years, due to advances in the treatment and monitoring of premature infants, their survival rates have significantly improved and their disability rates have decreased. Foreign scholars suggest that the upper limit of the defined time for preterm birth should be advanced to 20 weeks of pregnancy.

Causes of preterm birth
- 1. Premature rupture of membranes, chorioamnionitis.
- 2. Lower genital tract and urinary tract infections.
- 3. Pregnancy complications and complications.
- 4. Uterine overexpansion and placental factors
- 5. Uterine deformities.
- 6. The internal cervix is loose.
Clinical manifestations of preterm labor
- The main clinical manifestation of preterm labor is uterine contraction, which is initially irregular contractions, often accompanied by a small amount of vaginal bleeding or bloody secretions, and later develops into regular contractions. The cervical canal subsides first and then dilates.
Premature check
- Abdominal palpation for contractions. Examination of the cervical canal by vocal cord examination or ultrasound. Ultrasound assessment of fetal condition. Complications related tests.
Premature diagnosis
- Regular uterine contractions that occur at least once every 10 minutes from 28 weeks to less than 37 weeks of pregnancy, with shortened cervical canals, can be used to diagnose threatened preterm labor. Regular uterine contractions occur from 28 weeks to less than 37 weeks of pregnancy (no less than 4 times in 20 minutes and last no less than 30 seconds), with a cervical shortening of not less than 75%, and cervical dilatation of more than 2 cm. The diagnosis is preterm labor.
Preterm treatment
- General treatment
- Stay in bed, inhale oxygen, etc.
- 2. Drug treatment
- Tocolytic inhibitors to control infections and prevent neonatal respiratory distress syndrome.
- 3. Delivery
- Respiratory central inhibitors should be used with caution after childbirth; lateral incisions prevent intracranial hemorrhage in newborns.
Preterm prognosis
- The organs of premature babies are not well developed. The smaller the gestational age at birth, the lighter the weight, and the worse the prognosis.
Premature birth prevention
- 1. Regular prenatal check-ups, guide health during pregnancy, actively treat genitourinary tract infections, and control sexual life in the third trimester to prevent premature rupture of the membranes.
- 2. Strengthen the management of high-risk pregnancy, actively treat complications of pregnancy and complications, and prevent premature rupture of membranes and subclinical infections.
- 3. Intracervical sag, those undergoing intracervical cerclage at 14 to 18 weeks of pregnancy.
