The third stage of labor usually is eclipsed by the excitement of the birth of a baby. Evidence shows that management of this stage can directly influence important maternal outcomes such as blood loss, need for manual removal of the placenta, and postpartum hemorrhage. Most of the large trials have compared active management of the third stage to expectant management. Active management includes routine use of cord traction and uterotonins, whereas expectant management can be characterized as one of watchful waiting.
BACKGROUND: There are several Cochrane systematic reviews looking at postpartum haemorrhage (PPH) prophylaxis in the third stage of labour and another Cochrane review investigating the timing of prophylactic uterotonics in the third stage of labour (i.e. before or after delivery of the placenta). There are, however, no Cochrane reviews looking at the use of interventions given purely after delivery of the placenta.
ETHNOPHARMACOLOGICAL RELEVANCE: The convolvulacea Argyreia nervosa (Burm. f.) is well known as an important medical plant in the traditional Ayurvedic system of medicine and it is used in numerous diseases (e.g. nervousness, bronchitis, tuberculosis, arthritis, and diabetes). Additionally, in the Indian state of Assam and in other regions Argyreia nervosa is part of the traditional tribal medicine (e.g. the Santali people, the Lodhas, and others). In the western hemisphere, Argyreia nervosa has been brought in attention as so called "legal high".
