Comparison of Retia Medical (Long Time Interval Analysis) to Deltex Esophageal Doppler for Cardiac Output Measurement

A group of engineers at Michigan State developed a novel waveform analysis technique ("Long
Time Interval Analysis" [LTIA]) that attempts to estimate cardiac output non-invasively.
Retrospective comparison of LTIA to invasive techniques (e.g. thermodilution) suggest
acceptable agreement. Thus, a prospective trial of LTIA is warranted. This study compares
LTIA to a validated measure of cardiac output - esophageal Doppler monitoring.


Inclusion Criteria:

- Adult (18 years or older)

- Undergoing hepatobiliary surgery (open or laparoscopic) requiring general anesthesia
as part of the patient's clinical care

- Attending anesthesiologist plans to place an intra-arterial catheter for routine care

- Attending anesthesiologist believes that non-invasive cardiac output monitoring would
benefit the patient

Exclusion Criteria:

- Minors (17 years or younger)

- Parturient (pregnant women)

- Cognitively impaired

- Unable to sign informed consent form

- Prisoner

- Prior esophageal surgery

- Moderate to severe aortic regurgitation

- Mechanical cardiac support (e.g., intra-aortic balloon pump)

- Severe, persistent arrhythmias
