Shoulder dystocia is associated with an increased risk of birth injury to both the mother and baby. Some of the risks to the mother exist because medical providers may need to make a laceration (called an episiotomy) to dislodge the baby’s stuck shoulders. The laceration is made at the opening of the mother’s vagina, and it increases the risk of significant bleeding and nerve injury. If a larger laceration is required to deliver the baby, then it may cause injury to the mother’s sphincter. Other maneuvers used to address a shoulder dystocia can also increase the risk that the mother will suffer a bladder injury, uterine rupture, or urethral injury.
Shoulder dystocia also increases the risk of serious birth injuries to the baby. The most common birth injury for a baby to suffer due to shoulder dystocia is a brachial plexus injury. Briefly, the brachial plexus is a bundle of nerves that start in your neck and extend through your shoulders and down to your fingers. When a medical provider attempts to dislodge the baby’s shoulder from under the mother’s pubic bone, the provider may pull too hard on the arm or shoulder, stretching the brachial plexus nerves in the neck, which can result in injury to the nerves and loss of movement and sensation in the shoulder, arm or fingers. Brachial plexus injuries can be severe and permanent. If the medical provider causes a brachial plexus injury by pulling too hard on the baby, he or she may have committed medical malpractice and can be held responsible for the injuries they caused.
Shoulder dystocia also increases the risk the baby will suffer a severe brain injury at birth. Cerebral palsy is a type of brain injury that can result from medical malpractice during birth. The risk of brain injury increases with shoulder dystocia because, while the baby is stuck in the birth canal, the umbilical cord may be positioned or compressed in such a way that it stops providing the baby oxygen. If the baby is deprived of oxygen, he or she may suffer injury to their organs, including the brain. Brain injuries occurring near the time of birth can be severe, resulting in a number of permanent neurologic problems, including loss of muscle movement, and problems with speech, swallowing, behavior, and cognition. In some cases, a birth-related brain injury can result in the baby’s death.
