Objective

To demonstrate effectiveness of third stage of labor directed with intraumbilical oxytocin in the delivery room at Hospital "Dr. José María Carabaño Tosta", in Maracay, Aragua, Venezuela.

Type of study: Cross-sectional, carried out between February-August 2019.

Materials and methods

50 patients managed with third stage of labor led with 10 IU oxytocin through the umbilical vein (exposed group) and 50 patients managed with spontaneous third stage of labor (control group). We compared time of birth, blood loss and clinical outcome.

Results

Exposed group: 3.52 minutes average delivery time, average volume of the bleeding 112.8 ml and mean hemoglobin hematocrit value pre and post-delivery 11,01 gr/dl-34,3% and 10.7 gr/dl-32,4% respectively. Control group: 13,02 minutes average delivery time, average volume of bleeding 232,7 ml and mean hemoglobin hematocrit value pre and post-partum 11.3 gr/dl-34,9% and 10.1 gr/dl-31,2% respectively. The exposed group did not present any complication, while 4% of the control group presented uterine hypotonia and post-partum hemorrhage.

Conclusion

In the experimental group, the birth was significantly quicker and the lost blood were significantly lower (p: 0.000). We concluded that placenta with oxytocin via umbilical is more effective compared with spontaneous labor. There is no reason not to perform third stage of labor oxitocine in order to decrease obstetric hemorrhage risk and further complications.
