Overview

UsEn may better predict BP fluctuations than LF/HF during induction; hypothesis-generating and requires prospective validation before clinical use.

Structured PICO

Does non-linear analysis of HRV correlate better with haemodynamic fluctuations during induction of general anaesthesia compared to linear analysis?

P
Population
114 patients scheduled for general anaesthesia
I
Intervention
Non-linear analysis of heart rate variability (ultra short-term entropy, UsEn)
C
Comparator
Linear analysis of heart rate variability (LF/HF ratio)
O
Outcome
Correlation with haemodynamic fluctuation (blood pressure and heart rate) during induction of anaesthesiasurrogate

Non-linear HRV analysis (UsEn) may be a better predictor of blood pressure fluctuations during anaesthesia induction, while linear analysis (LF/HF) better predicts heart rate increases.
