Information for Patients

Childbirth Problems

While childbirth usually goes well, complications can happen. They can cause a risk to the mother, baby, or both. Possible complications include

  • Preterm (premature) labor, when labor starts before 37 completed weeks of pregnancy
  • Problems with the umbilical cord
  • Problems with the position of the baby, such as breech, in which the baby is going to come out feet first
  • Birth injuries

For some of these problems, the baby may need to be delivered surgically by a Cesarean section.

  • Assisted delivery with forceps
  • Brachial plexus injury in newborns
  • Breech birth
  • Caput succedaneum
  • Meconium aspiration syndrome
  • Premature rupture of membranes

Pregnancy and Substance Abuse

When you are pregnant, you are not just "eating for two." You also breathe and drink for two, so it is important to carefully consider what you give to your baby. If you smoke, use alcohol or take illegal drugs, so does your unborn baby.

First, don't smoke. Smoking during pregnancy passes nicotine and cancer-causing drugs to your baby. Smoke also keeps your baby from getting nourishment and raises the risk of stillbirth or premature birth. Don't drink alcohol. There is no known safe amount of alcohol a woman can drink while pregnant. Alcohol can cause life-long physical and behavioral problems in children, including fetal alcohol syndrome. Don't use illegal drugs. Using illegal drugs may cause underweight babies, birth defects or withdrawal symptoms after birth.

If you are pregnant and you smoke, drink alcohol or do drugs, get help. Your health care provider can recommend programs to help you quit. You and your baby will be better off.
