Descrizione dettagliata
The third stage of labor refers to the period following the completed delivery of the newborn until the completed delivery of the placenta. The length of the third stage and its complications are affected by the uterine contractility and the duration of placental separation. The normal duration of third stage in nulliparous as well as in multiparous women is less than 30 minutes. There is strong evidence supporting the routine administration of uterotonic agents for the prevention of post-partum hemorrhage (PPH), in order to enhance natural uterine contraction in the third stage of labor, thus reducing the occurrence of PPH by 40%.
There is a joint policy statement between the International Confederation of Midwives (ICM), the International Federation of Gynecology and Obstetrics (FIGO) and the World Health Organization (WHO), all of which recommend active management of the third stage of labor in order to prevent PPH. active management led to a reduction in PPH incidence, maternal Hemoglobin<9g/dL and need for blood transfusion. (4-7).
Active management of the third stage of labor involves prophylactic uterotonic treatment, early cord clamping and controlled cord traction to deliver the placenta. (2) Oxytocin is the first agent of choice for PPH prophylaxis because of its high efficacy and a low incidence of associated side effects. (6-9). Cotter et al found that the use of Oxytocin for PPH prophylaxis in the third stage of labor decreased the rate of maternal blood loss greater than 500 ml by approximately 50%. (10).
Oxytocin route of administration is either intravenously (IV) or intramuscularly (IM), with no significant difference in PPH incidence (9). This is based on a pharmacokinetic research from 1972 which found no difference between the absorption rates in both routes of administration. Since then no further research targeting this question was preformed. (11-12). recent guidelines from WHO, FIGO and ICM all recommended the use of 10 IU Oxytocin IM. (4, 7,13).
Previous studies have investigated the effect of intra-umbilical vein Oxytocin injection in reducing blood loss during the third stage of labor. This route of administration directs treatment to the placental bed and uterine wall, resulting in earlier uterine contraction and placental separation. However, limited published literature is available evaluating the effect of umbilical vein oxytocin injection in routine practices for active management of the third stage of labor. A prospective, randomized controlled trial of 412 women found that intra-umbilical injection of oxytocin alongside active management of the third stage of labor significantly reduced postpartum blood loss and the duration of the third stage (14).
Other uterotonic agents including Syntometrine (IM), Ergometrine (IM or IV) and Misoprostol (IM), can be used in active management of the third stage of labor. However, high quality evidence regarding their efficacy compared to Oxytocin is scarce. (9-10)
