Resumen
URDANETA MACHADO, José et al. Concentraciones séricas de zinc en embarazadas preeclámpticas y normotensas. Rev Obstet Ginecol Venez [online]. 2013, vol.73, n.1, pp.15-24. ISSN 0048-7732.
Objective: To compare serum concentrations of zinc in preeclamptic and normotensive pregnant. Methods: We performed a correlational, comparative and applied type research, with a not experimental, case-control, contemporary transactional and field design, which included 40 women in the third trimester of pregnancy with diagnosis pre-eclampsia and 40 normotensive pregnant; both cases as controls were analyzed for serum concentrations of zinc by atomic absorption spectrophotometry. Setting: Hospital Materno Infantil Dr. Raul Leoni in Maracaibo, Venezuela. Results: We found that preeclamptic patients had significantly lower concentrations of zinc to the normotensive (P <0.05), although average within normal ranges in both groups (76.42 ± 5.29 vs. 80.37 ± 2.7), presenting highly significant differences in mean arterial pressure between cases and controls (P <0.001). Also found no relationship between the variables mean arterial pressure and serum zinc concentrations in preeclamptic (P> 0.05), whereas in the normotensive group showed a significant and inversely proportional relationship (r = - 0.319, P <0.05). Conclusion: Pregnant women with pre-eclampsia had significantly lower serum zinc concentrations than normotensive, but there was no relationship between mean arterial pressure and zinc
