    Labor traditionally has been compartmentalized into three distinct stages [1]. The first stage of labor encompasses the latent and active phases of labor, and the length of this stage is a function of parity. The second stage begins with complete cervical dilation and effacement and ends with delivery of the infant. The third stage of labor is the amount of time between delivery of the infant and delivery of the placenta. The mean length of time is 6 minutes, and the ninety-seventh percentile is 30 minutes [2]. The amount of time from neonatal delivery to placental delivery is important because a direct relationship has been observed between that time interval and the risk of significant maternal morbidity.
