Differential effects of propofol and sevoflurane on heart rate variability.
BACKGROUND Propofol is reported to reduce both sympathetic and parasympathetic tone; however, it is not clear whether the changes in heart rate variability are associated with depth of anesthesia. The purposes of the present study were (1) to evaluate the changes in heart rate variability at different depths of hypnosis and (2) to compare the effects of propofol on heart rate variability with t...

15 صفحه اولEffects of propofol and thiopentone, and benzodiazepine premedication on heart rate variability measured by spectral analysis.
We studied the effects of temazepam premedication and induction of anaesthesia with thiopentone or propofol on the heart rate power spectrum in 47 patients undergoing elective minor surgery. Eighteen patients received temazepam 20 mg orally as premedication. There was a significant reduction in high frequency power and total power, and an increase in the ratio of low to high frequency power aft...
متن کاملThe different effects of intravenous propofol and midazolam sedation on hemodynamic and heart rate variability.
Heart rate (HR) and arterial blood pressure (BP) changes have been reported during conscious sedation with propofol and midazolam. One potential mechanism to explain these changes is that propofol and midazolam affect HR and BP via changes in the cardiac autonomic nervous system. Two specific hypotheses were tested by HR variability analysis: 1) propofol induces predominance of parasympathetic ...
متن کاملEffects of thiopental and propofol on heart rate variability during fentanyl-based induction of general anesthesia.
Anesthetics depress the autonomic nervous system. The effects of thiopental and propofol on heart rate variability (HRV) during fentanyl-based induction of general anesthesia were studied in one hundred patients. We observed different effects of fentanyl, thiopental and propofol on HRV. Fentanyl decreased total power of HRV and low frequency power (LF), but not high frequency power (HF), indica...
