Ultrasound-measured brachial artery reactive hyperemia in critically ill patients: an observational study.

ABSTRACT:

Background

Ultrasound-measured brachial artery reactive hyperemia (RH) is independently predictive of hospital mortality in critically ill patients with sepsis. Its association with mortality is uncertain in critically ill patients in general.

Methods

This was a combined case-control and prospective cohort study. Ultrasound was used to measure brachial artery reactive hyperemia in 150 critically ill patients at a single academic medical center and in 44 control subjects without acute illness. Measurements were compared in cases versus controls, septic vs. non-septic critically ill patients, and hospital survivors vs. non-survivors. Follow-up measurements were obtained 3-5 days later in a sub-sample of patients.

Results

RH was calculated as the percent change in pre- v
