Abstract

Background: assessment of bleeding during childbirth and postpartum is subjective and is generally underestimated, leading to serious complications and this increases maternal morbidity and mortality worldwide. Objective: evaluate the concentration of hemoglobin in peripheral blood lost between 12 and 24 hours after delivery by pregnant consulting in the department of obstetrics hospital Vicente Corral Moscoso and José Carrasco Arteaga city of Cuenca and the hospital San Sebastian Sigsig canton during June to September 2014.
