Brief Summary

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

NICOM® is a recently developed noninvasive cardiac output monitoring device, and indices derived from NICOM® such as SVV has been reported to predict fluid responsiveness in the previous studies. However, its usefulness in prone positioning has not been investigated. Thus, the aim of this prospective observational study is to evaluate the usefulness of stroke volume variation (SVV) derived from NICOM® to predict fluid responsiveness in prone patients undergoing spine surgery.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

All enrolled patients

This study enrolls patients undergoing elective spine surgery in prone position and all enrolled subjects may receive fluid loading with hemodynamic monitoring by Flotrac/Vigileo and NICOM, but the investigator does not assign specific interventions to the subjects of the study because this is a prospective observational study.
