ARRHYTHMIAS, SEPTIC SHOCK
Our study showed that in adult patients with septic shock, the changes in CPDV and cFT during EEOt on carotid Doppler are correlated with the changes in CI that occur after a fluid challenge, and that an increase in CDPV greater than 10.5% during a 20-s EEOt predicted fluid responsiveness with > 95% specificity. Carotid Doppler can be used to assess fluid responsiveness in patients who are sedated and mechanically ventilated and without arrhythmias, when invasive hemodynamic monitoring is not immediately available. However, its large gray zone is an important limitation.
