Heart rate variability analysis
Heart rate variability analysis was performed according to the Task Force recommendations. Frequency domain analysis was based on fast Fourier transformation. Power spectrum densities were calculated for low frequencies (LF: 0.04-0.15 Hz) and high frequencies (HF: 0.15-0.4 Hz) informalized units, defined as the LF or HF proportional part of the total power. Baseline and 30min after the injection of the study drug.
5min perioids after fluid resuscitation.
