OBJECTIVE: Vasoconstriction during @entity148 reduces fetal oxygenation and leads to @entity519 . @entity519 in turn results in increase of the number of nucleated red blood cells (NRBCs) in the cord blood. The present study aimed to assess the effect of decreasing maternal @entity148 on fetal oxygenation and NRBCs count in the cord blood. METHODS: . In this study, 150 @entity1 were randomly divided into two intervention groups [supportive care and acupressure in BL32 (bladder) acupoint] and a control group (hospital routine care). The @entity1 ' cord blood was investigated regarding the number of NRBCs and the intensity of @entity519 after birth. Then, the data were entered into the SPSS statistical software (v. 16) and analyzed using ANOVA, Chi-square test, and logistic regression analysis. Findings : The significant difference was found between the two groups regarding the number of NRBCs counted in the peripheral blood smear (P<0.001). Besides, a significant relationship was observed between the length of the first and second stages of labor and the number of NRBCs in the cord blood (P=0.01). Also, a significant association was observed between the type of delivery and the number of NRBCs in the cord blood in both intervention (P<0.001) and control groups (P=0.03). CONCLUSION: Doula supportive care and acupressure at BL32 point reduced the length of labor stages as well as the @entity148 level. Also, nucleated red blood cells were less in the 2 groups of intervention than in control group. Regarding the fact that nucleated red blood cells cannot be the only factor for @entity519 predicting, for affirmation of this theory study with higher sample size and survey of mothers at high risk are needed.
