Intraumbilical Vein Injection of Oxytocin in Routine Practice for Active Management of the Third Stage of Labor
- Registration Number
- NCT01094028
- Lead Sponsor
- Erzincan Military Hospital
- Brief Summary
During the first hours that follow the birth of the baby (third and fourth stages of labor), complications are common and can threaten the mother's life. The most common complication is postpartum hemorrhage (PPH), which remains a leading cause of maternal mortality (25.0%) especially in developing countries .Three to five percent of deliveries are complicated by PPH and is 50 times more common in developing countries. Retained placenta is an another complication of third stage of labor. It complicates 0.1-2 % of deliveries . Without prompt treatment, women are at high risk of hemorrhage. At present, treatment is by manual removal of placenta, which needs an operating theatre, a surgeon, and an anaesthetist-facilities that are often unavailable to women in resource-poor settings. As a result, this condition has a case fatality rate of nearly 10% in rural communities.
The length of the third stage of labor, and its subsequent complications depends on a combination of the length of time it takes for placental separation and the ability of the uterine muscle to contract. Principal management of the third stage of labor is aimed at reducing the time of delivery of placenta so minimising serious adverse effects, such as blood loss and retained placenta. Active management of the third stage of labor, which includes prophylactic injection of 10 units of oxytocin within two minutes of birth, early clamping of the umbilical cord and controlled cord traction (CCT), is recommended by WHO for PPH prevention .
Umbilical vein oxytocin injection directs the treatment to the placental bed and uterine wall, resulting in an earlier uterine contraction and placental separation. However, very limited published literature is available, which evaluated the effect of umbilical vein oxytocin injection in routine practices for active management of the third stage of labor. The purpose of this investigation was to find out the beneficial effect of adding intraumbilical vein oxytocin in reducing the blood loss during third and fourth stages of labor, length of third stage of labor, and reduction in the incidence of manual removal of retained placenta.

- Arm && Interventions
Group Intervention Description Saline group Oxytocin Only 30 mL of saline was injected directly in the umbilical vein after clamping. The injection was performed with a 30-mL syringe and an 18-gauge needle around 1 to 2 cm from the introitus. The solution was injected slowly over 1 minute and at the end of the injection, the solution was milked toward the cord insertion.
- Primary Outcome Measures
Name Time Method the amount of blood loss in third and fourth stages of labor The end of the delivery to 2 hours after birth.
- Secondary Outcome Measures
Name Time Method duration of the third stage The duration of the third stage of labor was defined as the time difference (in minutes) between delivery of the infant and delivery of the placenta. The time interval was measured by the nurse attending the delivery and confirmed by the physician using a digital stop clock. The clock was started as soon as baby's body was totally delivered and stopped as soon as the placenta was completely expulsed.
