Why the study?
Does propofol compared to sevoflurane affect heart rate variability and cardiac parasympathetic tone during anesthesia induction?
Does propofol compared to sevoflurane affect heart rate variability and cardiac parasympathetic tone during anesthesia induction?
Propofol reduces cardiac parasympathetic tone depending on the depth of hypnosis during anesthesia induction, whereas sevoflurane has little or no effect.
No takes yet. Share an insight, caveat, or question.
Propofol's BIS-dependent parasympathetic suppression may affect induction hemodynamics; leaves open confirmation in prospective trials.
Kanaya et al. (2003) studied this question.
