Overview

Symbolic HRV parameters may track hypnosis depth and nociception; leaves open utility for guiding anesthesia in stable CV patients.

Structured PICO

Do heart rate variability parameters reflect changes in depth of hypnosis and nociception during general anaesthesia in cardiovascular stable patients?

P
Population
Cardiovascular stable patients (ASA Score I/II, N = 32, age: 36.4 ± 11.23 years, BMI: 25.2 ± 3.16) scheduled for trauma and dentofacial surgery.
E
Exposure
Standardized intravenous propofol-remifentanil-anaesthesia with peri-operative electrocardiogram recording.
C
Comparator
Comparisons between longitudinally distributed 300 s intervals preceding/following induction of anaesthesia (BL-I1), intubation (I1-I2) and extubation (E1-E2).
O
Outcome
Heart rate variability (HRV) time- and frequency-domain parameters, measures of complexity and nonlinear dynamics.surrogate

Parameters of symbolic dynamics in heart rate variability appear to be specifically influenced by changes in depth of hypnosis and nociception during general anaesthesia.

Limitations

  • Lack of steady-state ventilation/breathing
