GUERRA, Mery et al. Apgar y variables hematológicas en pacientes con anemia materna crónica severa y trabajo de parto normal. Rev Obstet Ginecol Venez [online]. 2008, vol.68, n.1, pp.5-11. ISSN 0048-7732.

Objective: To establish an association of Apgar with hematological variables in patients with severe chronic maternal anemia and labor. Method: Ninety patients were selected with a diagnosis of severe chronic anemia and labor to be included in the research. Peripherical blood was recollected from antecubital vein to quantify concentrations of hemoglobin, vitamin B12, folic acid, serum iron and ferritin. Once the newborn was assisted Apgar at minute and at five minutes was determined. Setting: Maternidad "Dr. Nerio Belloso". Hospital Central "Dr. Urquinaona". Maracaibo, Estado Zulia. Results: Mean value of Apgar at minute was 6.9 ± 0.8 and at five minutes of 8.7 ± 0.4 points. Mean value of vitamin B₁₂ was 342.2 ± 80.5 ng/mL and folic acid was 7.7 ± 8.2 ng/mL. Serum iron concentration was 46.3 ± 42.4 mg/dL and ferritin concentration was 37.1 ± 35.5 pg/mL. There was only a weak negative correlation and statically significant between five minute Apgar and serum concentration of vitamin B₁₂ (r = - 0.256; P < 0.05). Conclusions: There is not significant statical association between Apgar and severe chronic maternal anemia in patients with normal labor, even though a negative correlation was seen between vitamin B₁₂ concentrations and at five minutes Apgar.
