Material y métodos:  Se implementó un protocolo estandarizado de cuantificación gravimétrica del sangrado postparto en pacientes sometidas a cesárea. Un estudio prospectivo, comparativo, no aleatorizado determinó el cumplimiento del protocolo, frecuencia proporcional del sangrado postparto anormal, basal y postintervención de mejora; y asociación entre metodologías de evaluación del sangrado y clasificación del sangrado. Pruebas z, Fisher, p &lt; 0.05 significativa.  Resultados:  El cumplimiento del protocolo estandarizado fue 53% (± 0.18). En el grupo postintervención de mejora, la frecuencia del sangrado anormal postparto se incrementó en 30% con respecto al grupo basal (p &lt; 0.05). Se demostró asociación significativa entre la cuantificación gravimétrica del sangrado postparto, y el sangrado postparto anormal.

<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Introduction:  Postpartum hemorrhage is a complication, that is not timely detected with the visual estimation of bleeding.  Material and methods:  A standardized protocol for the gravimetric quantification of postpartum bleeding was implemented to improve the ability to identify abnormal bleeding in patients undergoing caesarean section. A prospective, comparative, non-randomized study evaluated the improvement intervention. Compliance with the protocol, classification of postpartum bleeding before and after intervention; and the association between methodologies for assessing bleeding and postpartum bleeding classification were determined. Fisher z tests, p &lt; 0.05 significant.  Results:  Compliance with the standardized protocol was 53% (± 0.18). In the post-intervention group, the frequency of abnormal postpartum bleeding increased by 30% with respect to the baseline group (p &lt; 0.05). A significant association was demonstrated between gravimetric quantification of postpartum bleeding and abnormal postpartum bleeding.  Conclusion:  The implementation of the protocol for the gravimetric quantification of postpartum bleeding was possible. It improved the ability to identify abnormal postpartum bleeding in patients undergoing cesarean section.]]></p></abstract>
