Information provided by (Responsible Party):
University of California, San Francisco
  Purpose
  1. Compare measurements of cardiac output derived from electrical measurements from electrodes on an endotracheal tube (ECOM or Endotracheal Cardiac Output Monitor) to those made from a pulmonary artery thermodilution catheter.
  2. Establish the safety and efficacy of the ECOM system.

Condition Intervention Phase
Cardiac Output Device: Placed ECOM endotracheal cardiac output monitor in patients undergoing cardiac surgery Phase 2 Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: Impedance Cardiography: Clinical Evaluation of Endotracheal Cardiac Output Monitor (ECOM)

Further study details as provided by University of California, San Francisco:

Primary Outcome Measures:
  • Comparison of ECOM Impedance and Thermodilution Cardiac Output Measurements [ Time Frame: perioperative period ]

    Correlation measured via Linear regression between thermodilution and ECOM, included as r^2 coefficient.

    Cardiac output measured by iced-thermodilution and impedance cardiography. Management of the patients done using (standard) thermodilution derived cardiac output measurements only. The ECOM endotracheal cardiac output measurements are for research purposes only and not used in the management of the patient.

    ECOM Impedance cardiography measured in the ICU when routine thermodilution cardiac output measurements are made. Endotracheal impedance measurements (ECOM) continued until tracheal extubation. Correlation with thermodilution measurements stopped when either the endotracheal tube or the thermodilution catheter was removed (post op day 0 routinely).



Secondary Outcome Measures:
  • Safety of Device Measured by Number of Participants With Adverse Events [ Time Frame: perioperative period ]
    Patients were interviewed postoperatively for all complications and specifically for complications related to intubation and/or cardiac output measurements


Enrollment: 261
