|Condition or disease||Intervention/treatment|
|Fluid Responsiveness Modified Prone Position||Other: volume expansion|
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.
- To assess influence of the position change on PVI and other variables(PPV, SVV)
- To assess PVI to predict fluid responsiveness at modified prone position
|Study Type :||Observational|
|Estimated Enrollment :||45 participants|
|Official Title:||Pleth Variability Index as Predictors of Fluid Responsiveness in Modified Prone Position(Concord Position) or Knee-chest Position|
|Actual Study Start Date :||December 6, 2019|
|Estimated Primary Completion Date :||January 31, 2021|
|Estimated Study Completion Date :||March 31, 2021|
- Other: volume expansion
To assess fluid responsivenessOther Name: If stroke volume of FloTrac® decrease 15 % of baseline, crystalloid loading of 4ml/kg will start.
- To assess influence of the position change on PVI and other variables(PPV, SVV) [ Time Frame: 1.supine position : 5 minute after anesthesia induction with arterial-line insertion 2. 5 min after crystalloid 4 ml/kg loading / 3. modified prone position (baseline) ]When position change from supine to modified prone position, to assess the change of PVI and other variables. The correlation of PVI and cardiac output during this change.
- To measure dynamic variables (pulse pressure variation, stroke volume variation and pleth variability index) in modified prone position [ Time Frame: 1. Supine position : 5 minute after anesthesia induction with arterial-line insertion 2. 5 minute after a position change to prone 3. before and after fluid loading ]Record the data of variables after 5 minute hemodynamic stability without changes of drugs
