Overview
This study aims to analyze whether there is a significant difference in the occurrence of postpartum hemorrhage between women who underwent umbilical cord drainage and those who did not. Variables such as estimated blood loss volume, drop in hemoglobin levels, and the need for additional maneuvers or treatments to control hemorrhage will be examined. The research will be conducted under a parallel-group clinical trial design at the Hospital Escuela Universitario. Post-birth umbilical cord drainage may contribute to a lower frequency of postpartum hemorrhage compared to not performing it.
Description
This is a single-blind, parallel-group, superiority efficacy clinical trial. The intervention involves passive drainage of blood from the umbilical cord immediately after cord clamping and cutting, allowing it to flow into a calibrated drape. The control group receives standard active management of the third stage of labor without cord drainage. The primary objective is to compare postpartum blood loss between the groups. Secondary objectives include comparing pre- and postpartum hemoglobin levels, the need for additional therapeutic interventions (uterotonics, uterine revision, transfusion), incidence of adverse events related to cord management, and maternal satisfaction using the Birth Satisfaction Scale. The study plans to enroll 400 participants (200 per group) over approximately 6 months at a single center.
