[3] Factors that place a woman's pregnancy at higher risk include advanced maternal age, Premature Rupture of Membranes (PROM) and induction of labor.

Oxytocin is a natural hormone and a uterotonic agent which stimulates the uterine muscles to contract and initiate labour.

Afterward, if beneficial and uterine tone has returned to baseline and fetal status is stable, oxytocin as a labor augmenting agent may be resumed.

Post-partum hemorrhage is defined by the loss of at least 1,000 mL of blood accompanied with symptoms of hypovolemia within 24 hours after delivery.

[25] As a result of discrepancies in diagnostic criteria and human variability, there is wide variation in data on maternal and fetal death associated with poor progress.

[27] An analysis has showed that preventive antibiotics reduce the risk of infection after an assisted vaginal birth, irrespective of whether a woman has had a perineal tear, an episiotomy, or both.

[28][29] Spontaneous vaginal delivery at term is the preferred outcome of pregnancy, and according to the International Federation of Gynecology and Obstetrics, will be recommended if there are no evidence-based clinical indications for Cesarean section.

[31] Controversy and debate surround the topic due to different views on the preferred route of delivery when breech presentation occurs.
