Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Heart rate variability analysis | 5min perioids after fluid resuscitation. | 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. |
| Secondary | Epidural injection | at 30 min after the epidural injection of the study drug | And secondary data collection was done at 30 min after the epidural injection of the study drug. All of the HRV analysis was done before anaesthesia induction. |
