Clinical Trial Summary

The purpose of this study is to validate Rainbow pleth variability index for prediction of fluid responsiveness in children.


Clinical Trial Description

Children undergoing surgery under general anesthesia will be enrolled. After anesthetic induction, they will be assessed via transthoracic echocardiography for measurement of the patient's stroke volume index (SVI). Also, pleth variability index and Rainbow pleth variability index will be measured under mechanical ventilation with tidal volume of 6, 8, 10 ml/kg. To exert fluid loading, 10ml/kg of crystalloid solution will be administered intravenously over 10 minutes. After fluid loading, the SVI will be measured again and fluid responsiveness will be determined according to increment ratio of the SVI. According to the determined fluid responsiveness, predictive power of pleth variability index and Rainbow pleth variability index for fluid responsiveness will be assessed by building a receiver-operating characteristics curve. ;
