Samsung Medical Center

Status: Completed

Conditions: Non Invasive Cardiac Output Monitoring; Prone Position; Fluid Responsiveness

About

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.

Enrollment: 40 patients

Sex: All

Ages: 20 to 80 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• ASA I or II patients undergoing spine surgery in prone position

Exclusion criteria

• Pre-existing arrhythmic disorders/moderate to severe valvular heart disease/obstructive pulmonary disease (COPD grade >2), left ventricular dysfunction with LV EF less than 50, preoperative need for inotropics or vasopressors
• BMI >30kg/m^2 or <15kg/m^2
• Preoperative serum Cr > 1.3mg/dL
• Patients with coagulopathy

Trial design

40 participants in 1 patient group

All enrolled patients

Description:

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.

Treatment:

Other: Fluid loading to evaluate fluid responsiveness
