ABSTRACT
Introduction and Aims: one of the most important causes for maternal death in developing countries is the third stage bleeding. The main aim of this study is to compare the effect of milking umbilical cord with diluted oxytocin and normal saline injections in the umbilical cord vein, on labor third stage duration and bleeding
Materials and Methods: the randomized control trial was done on 168 parturient mothers in Ahvaz hospitals. In the first group [N = 56] the umbilical cord blood was milked toward the placenta, the mothers in second group [N = 44] and third group [N = 32] were received 20 IU oxytocin and 30 ml saline normal in umbilical cord vein, respectively. Finally the forth or control group [N = 36] were received infusion of 20 IU oxytocin in 1000 ml serum ringer as the routine postpartum care. Then collected data was analyzed in SPSS v.16 by statistical tests, paired t-test, and ANOVA [CI = 95%]
Results: mean duration of third stage of labor was significantly different between groups [P = 0.02], but all three manipulated groups did not have any significantly difference whereas, the difference was between control and manipulated groups. The effect of milking the umbilical vein toward placenta is similar to the other manipulations in third stage duration. Mean hemoglobin concentration was not importantly different between the groups
Conclusion: milking the umbilical cord blood toward placenta could reduce the duration of labor third stage the same as the others [diluted oxytocin and saline normal in umbilical vein]. While this new method is easier and more available
ABSTRACT
Iron in the diet can influence the absorption of certain elements including zinc [Zn] and magnesium [Mg]. In this study the effect of iron supplementation on zinc and magnesium concentrations in maternal milk and, plasma at puerperal period were evaluated. Ninety nine non anemic mothers with single pregnancy and normal delivery were randomly enrolled in two groups [iron and placebo group]; blood samples were collected at the time of delivery and also 140 mid 40 days after delivery. Milk samples were collected twice; at two weeks [transient milk] and 40 days after the delivery [mature milk]. They were supplemented orally with either 150mg ferrous sulfate or placebo from the time of delivery for 40 days. Zinc and magnesium concentrations were measured using atomic absorption spectrometry. The maternal dietary intake for zinc and magnesium were similar between two groups. Mean iron indexes [ferritin, serum iron and TIBC] were not significantly different between two groups at the time of delivery. No significant differences in Zn and Mg levels were detected in maternal milk between two groups but in plasma although there was no significant difference in plasma magnesium concentrations; The zinc concentrations was significantly [p<0.001] decreased in the group receiving iron supplementation [0.076 +/- 0.047mg/dL] compared with the group receiving placebo [0.163 +/- 0.137] until 40 days after delivery. Data from this study suggest that iron supplementation does not affect the contents of these elements in maternal milk but despite the possible improvement in body iron status, it can decrease the plasma zinc concentrations, so the zinc supplementation may be needed with iron
