Observational Study of Fetal Monitoring in Different Maternal Positions at More Than 3600 Masl Huancavelica, 2021

This research aims to determine the effect of maternal left lateral decubitus and Fowler positions on electronic fetal monitoring at more than 3600 Masl-Huancavelica, 2021. Method: the research was pre-experimental, prospective, and longitudinal analytical; the level of research is explanatory; normality was evaluated with the Shapiro-Wilk statistician and statistical analysis with the Wilcoxon signed-rank test sample: 35 pregnant women between 32 and 42 weeks. Each one underwent two NST of 20 minutes (LLD and Fowler). Results: the average age was 25 years old and a mean of 37.26 weeks of gestational age; 37.1% were primigravida, 42.9% second gestation and 20% multiple gestations; in the NST in the LLD position, it was found: that 91.4% reactivity, 8.6% non-reactive, there were no pathological, while in the Fowler position: 74.3% presented reactivity, 20.0% non-reactive and 5.7% pathological. The baseline in LLD was 136.06, compared to 139.31 in Fowler. The mean of variability and accelerations was 10.51 and 4.49 in LLD and 9.63 and 3.43 in Fowler; few NSTs were identified with mild variable decelerations of 0.34 and 0.09, and fetal movements were 13.11 and 10.40, respectively. There is a significant difference in the baseline, showing less in LLD (“p” value 0.000). Conclusions: The LLD position shows better results than the non-stress test; a significant difference has been found in the baseline, while the variability, acceleration and movements are similar in both positions with a significance of 0.05.
