Fig. 2From: Observations on significant hemodynamic changes caused by a high concentration of epidurally administered ropivacaine: correlation and prediction study of stroke volume variation and central venous pressure in thoracic epidural anesthesiaHemodynamic changes following epidural administration of ropivacaine. MAP (P = 0.039) and SVRI (P = 0.026) were significantly decreased in 0.75% ropivacaine group compared with other groups. Concordant increase in SVV was remarkably increased in 0.75% group compared with 0.375% and 0.2% group through the study period (P = 0.017). * mean P < 0.05 compared with 0.2% group and † means P < 0.05 compared with 0.375% groupBack to article page
