Why the study?
Do heart rate variability metrics provide an accurate method of monitoring depth of anesthesia and response to painful stimuli in children receiving propofol anesthesia?
Do heart rate variability metrics provide an accurate method of monitoring depth of anesthesia and response to painful stimuli in children receiving propofol anesthesia?
Power spectral analysis of heart rate variability may be an accurate and clinically useful measure of depth of propofol anesthesia and sympathetic response to pain in children.
Answers are grounded in this paper and cite their sources.
Single-case HRV changes with pain under propofol warrant no practice change; leaves open validation for pediatric anesthesia monitoring.
