Input: We included nine studies involving 1118 women. We identified four comparisons. One comparison included six studies (which randomised 394 women) comparing umbilical vein injection of normal saline plus oxytocin versus that of normal saline, as well as three other comparisons, each of which includes one study. Comparing intraumbilical injection of normal saline plus oxytocin with intraumbilical injection of saline only, there was no evidence of difference in any of the relevant outcomes reported namely the number of women who required blood transfusion, the incidence of manual removal of placenta, blood loss, and length of the third stage of labour. Subgroup analyses by both total amount of solution administered and dose of oxytocin showed no evidence of difference. Other comparisons included only one study for each, and there was no relevant information available. Routine use of oxytocin or any other uterotonics with normal saline via umbilical vein injection is not recommended until new evidence is available. Further research should be conducted to show effectiveness of oxytocin with normal saline via umbilical vein injection.
Output:

This review included nine randomised controlled trials involving 1118 women and assessed six of these studies (involving 394 women) comparing umbilical vein injection of normal saline with or without oxytocin. Other comparisons did not provide the required information. With umbilical vein injection of saline solution plus oxytocin versus umbilical vein injection of saline solution there was no evidence of a difference in the amount of blood lost, duration of the third stage of labour or need for manual removal of a retained placenta. routine use of umbilical injection after childbirth to deliver any infusion, though the combined results of the small number of relevant studies showed no evidence of effect and further research is needed to make a conclusion. There is a need for training in the technique and a possible higher cost of materials.
