Scoliosis Clinical Trial
Official title:
Accuracy of Pleth Variability Index (PVI) in Predicting Response to Intravenous Fluid Load During Scoliosis Surgery in Children
Plethysmographic Variability index is a simple index accurate in predicting fluid
responsiveness.
The aim of this study was to investigate its accuracy in predicting fluid response to
intravenous fluid challenge during scoliosis surgery in children.
The goal of the present study is to assess the validity of PVI in predicting the response to
a fluid challenge during scoliosis surgery in children.
During this observational non-interventional study, each fluid challenge will be monitored
by esophageal Doppler and PVI (Massimo Radical 5).
Anesthesia, surgery and intraoperative fluid administration id standardized according to our
clinical protocol.
An increase in indexed Stroke Volume (iSV) by more than 15 % will define the positive
response to the fluid challenge.
Fluid challenges will be performed in the supine position and in the prone position.
Statistical analysis will performed using the Receiving Operator Characteristics (ROC) curve
with determination of the gray-zone allowing an error tolerance of 10 %.
