As Missouri parents may know, birth injury due to obstruction is a condition associated with overweight neonates. Recent studies have pointed to benefits derived from induction of labor at 37 to 38 weeks to avoid this problem. The benefits are particularly noticeable when the baby is large for gestational age.
Large infants have a greater incidence of birth injuries, such as shoulder dystocia, which is a particular type of obstructed labor. This occurs when the infant has partially delivered, but either one shoulder or both are caught behind the pubic bone preventing the infant from being born. This may result in damage to the baby's nerves, loss of oxygen and fractures.
