Sasha Shillcutt MD, University of Nebraska
ClinicalTrials.gov Identifier:
NCT01780727
First received: January 23, 2013
Last updated: July 5, 2017
Last verified: July 2017
  Purpose
Elderly patients are the fastest growing surgical population and present with increased risk of postoperative cardiac problems, especially congestive heart failure. Diastolic dysfunction is common in the elderly population and increases the risk of major adverse cardiac events after surgery. This project will use dynamic measurements of diastolic filling pressures by echocardiography for goal-directed fluid and drug management during surgery to determine whether this reduces serious cardiac events related to diastolic dysfunction after surgery in this high-risk population.

Condition Intervention
Ventricular Dysfunction, Left Major Adverse Cardiac Events Procedure: EGHEM

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Arm 1 receives normal saline per the standard of care determined by the anesthesiologist.

Arm 2 receives normal saline or furosemide per the results of the intraoperative echocardiogram.

Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Echocardiography-guided Hemodynamic (EGHEM) Management Strategy to Improve Clinical Outcomes for Elderly Patients With Left Ventricular Diastolic Dysfunction (LVDD) Undergoing Non-cardiac Surgery

Further study details as provided by Sasha Shillcutt MD, University of Nebraska:

Primary Outcome Measures:
  • Number of Patients who undergo dynamic heart function changes during surgery [ Time Frame: 2 years ]

    We will test the hypothesis that Left Ventricular Diastolic Dysfunction (LVDD) undergoes dynamic changes perioperatively.

    A. We will preoperatively identify 200 elderly subjects to provide 80% power to detect a change in LVDD undergoing noncardiac surgery using a 0.01 level two-sided paired t-test.

    B. We will assess changes in LVDD in these subjects based on hourly intraoperative echocardiography data points.



Secondary Outcome Measures:
  • Safety of Echo-Guided Hemodynamic Management during surgery [ Time Frame: 1 year ]

    We will test the hypothesis that goal-directed Echocardiography Guided Hemodynamic Management (EGHEM) used in elderly subjects with LVDD improves postoperative clinical outcomes.

    A. We will determine the ability of goal-directed EGHEM to maintain or improve intraoperative LVDD.

    B. We will determine the ability of goal-directed EGHEM to reduce postoperative Major Adverse Cardiac Event (MACE)



Estimated Enrollment: 120
