Abstract

Purpose of investigation: To investigate the differences in autonomic nervous activity of women in the sitting and supine positions. Materials and Methods: Autonomic nervous activity (high frequency (HF) and low frequency (LF) (ratio LF/HF) and vital signs of 42 women were determined on the first postpartum day. Results: In both primiparous and multiparous women, HR was significantly lower in the supine than in the sitting position (p < 0.001). Primiparous women showed higher HF in the supine than in the sitting position, whereas in multiparous women, HF was significantly higher in the sitting than in the supine position (p < 0.05). LF/HF was significantly higher in the sitting than in the supine position in primiparous women (p < 0.001). Conclusion: Significant differences between the sitting and supine postures may be due to differences in hemodynamics. Furthermore, in multiparous women, there is a possible absence of autonomic nervous balance on the first postpartum day.
