Changes in Baroreflex Sensitivity in Head-Down Tilt Position

2016 ARC Journal of Anesthesiology  
TO THE EDITOR Autonomic nervous system activity can be monitored by analyzing the relationship between spontaneous fluctuations of blood pressure and heart rate, known as the baroreflex. The clinical significance of baroreflex sensitivity (BRS) has been reported [1]. However, physiological alterations in BRS under general anesthesia have not been evaluated. We report the effect of steep head-down tilt with pneumoperitoneum on BRS during robot-assisted laparoscopic prostatectomy (RALP). We
