Why the study?
Does the ultrasonic cardiac output monitor (USCOM) accurately measure stroke volume changes compared to the oesophageal Doppler monitor (ODM) in patients undergoing major abdominal surgery?
Population

May not yet replace oesophageal Doppler for perioperative monitoring; leaves open USCOM utility in larger validation studies.
Does the ultrasonic cardiac output monitor (USCOM) accurately measure stroke volume changes compared to the oesophageal Doppler monitor (ODM) in patients undergoing major abdominal surgery?
USCOM shows good concordance and accurately discriminates clinically significant changes in stroke volume compared to ODM during major abdominal surgery.
Hodgson et al. (2015) studied this question.
