Definition

Information about the initiating event of a woman’s delivery, the mode of delivery, and if it was an assisted delivery.

Purpose

The mode of delivery may influence the health of the mother. Cesarean deliveries are becoming more common in the United States, often performed without a medical reason, and put the mother at increased risk of infection, hemorrhaging, blood clots, or experiencing a reaction to the anesthesia. Mode of delivery may also impact the health of the neonate. Cesarean section in the absence of labor has been associated with an increased occurrence of difficulties in respiratory transition to newborn life; for example, an increased risk of transient tachypnea of the newborn. Instrumental vaginal deliveries (forceps and vacuum) have been associated with increased risk of birth injuries such as facial nerve damage (forceps) and subgaleal hematomas (vacuum).
