Background: Postpartum hemorrhage (PPH) is one of the leading causes of maternal death worldwide. It affects 2% of women in labor worldwide and 24% of maternal deaths occurred in Essalud nationwide correspond to PPH. Currently, there is no method that helps us to accurately determine blood loss in the postpartum period, however there are studies that show that visual estimation is the most imprecise and the least reliable. The objective of this study is to determine the correlation between the visual estimation of postpartum hemorrhage with the variability of hemoglobin pre and post vaginal delivery in patients treated at the Department of Gynecology and Obstetrics of the National Hospital Adolfo Guevara Velasco - ESSALUD Cusco, Peru during the period from October to December of the year 2019. Methods: A retrospective, cross-sectional, analytical, correlational study was carried out at the Obstetric Gynecology Service of the HNAGV Essalud, Cusco. Patients with single vaginal deliveries were included, with hemoglobin analysis before and after delivery. Data analysis: Spearman Correlation Coefficient, descriptive analysis with Standard Deviation, bivariate analysis with 95% confidence interval, p <0.05. Results: There is a Spearman coefficient of 0.04 between visually estimated blood loss and actual blood loss. The level of hemoglobin variability was 1.74 g / dl ± 1 g / dl. The mean of the blood loss by visual estimation was 172 ml ± 78.7 ml. Most of the patients were between 25 and 35 years old, came from urban areas, with a gestational age at term at the time of delivery. 64.5% of patients had a prepartum hemoglobin within normal parameters, and 86.9% of patients, moderate anemia after delivery. 52% presented postpartum hemorrhage undiagnosed by visual estimation. There is a statistically significant association between the patient's origin, retention of placental remains, antepartum anemia, and the second period of delivery, with the actual postpartum blood loss. Conclusions: There is a weak correlation between visually estimated blood loss and the loss calculated by hemoglobin variability, dismissing the use of visual estimation as a diagnostic method of PPH.
