Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To investigate whether PVI predicts the fluid responsiveness in modified prone position undergoing posterior approach cervical operation. Furthermore, modified prone position could influence on dynamic variables including stroke volume variation(SVV), pulse pressure variation(PPV) and PVI.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objective :

To compare measurements of pleth variability index (PVI), pulse pressure variation (PPV) and stroke volume variation (SVV) to predict fluid responsiveness in modified prone position or knee-chest position (concord position) for cervical operation.

To identify Influence of the modified prone position (concord position) on these variables.

Method

1. To assess influence of the position change on PVI and other variables(PPV, SVV)
2. To assess PVI to predict fluid responsiveness at modified prone position
