ABSTRACT
Objective: Determinate the association between adverse perinatal outcomes and anemia in pregnant women.Materials and Methods: Observational, prospective-retrospective and cross-sectional study. Including women in birth labor attended at Hospital General Dr. Salvador Zubirán Anchondo in Chihuahua City, during March to October 2017. Inclusion criteria considered women with single pregnancy. Exclusion criteria with present conditions: congenital deformities, use of anticoagulants, blood diseases, preeclampsia, HELLP syndrome, instrumental delivery with forceps, dystocia, maternal diabetes, kidney and liver diseases, use of tobacco and other drugs. Adverse perinatal outcomes included were: miscarriage risk, preterm labor, preterm birth, pre labor rupture of membranes, urinary infection, low birth weight, Apgar score at birth and after five minutes, obstetric hemorrhage. Patients were interviewed to evaluate obstetric background; blood venous sample was taken to determine haemoglobin, hematocrit, red blood cells number, medium corpuscular volume, medium corpuscular hemoglobin concentration. Birth data was registered from medical records.
Results: Two groups were integrated: with anemia (n=172) and without anemia (n=879). Patients with anemia were those with haemoglobin less than 11 g/dL or hematocrit less than 33% according World Health Organization anemia classification: mild 10-10.9 g/dL, moderate 7-9.9 g/dL and severe less than 7.0 g/dL. Anemia frequency was calculated in 16%, mild anemia frequency was 10% (111 patients), 6% moderate and severe anemia (n = 61). Both groups developed patients with adverse perinatal outcomes. Transfusion of blood products showed higher frequency in anemic patients (9% versus 1% control group).
Conclusion:: Anemia prevalence calculated in 16% associated with transfusion of blood products, during puerperium or after c-section period.
