Abstract

CRUZ JIMENEZ, María del Carmen et al. Correlation of cardiac output obtained by termodulution and by ultrasonic monitor in patients with septic shock (USCOM). Med. crít. (Col. Mex. Med. Crít.) [online]. 2018, vol.32, n.4, pp.191-200.  Epub June 30, 2020. ISSN 2448-8909.

The pulmonary artery catheter (CAP) is a device used in intensive care units (ICUs) to measure pressures in the heart and pulmonary blood vessels as part of hemodynamic monitoring primarily in cardiac surgery patients. The USCOM device is a non-invasive technique that uses Doppler technology to obtain measurements of systolic volume and its derivatives.

The following CO measurement comparison is performed between these two devices in patients with septic shock.

An observational, prospective, longitudinal and comparative study was conducted in patients with septic shock aged between 18 and 60 years admitted to intensive care in the period May-June 2017.

In view of the decrease in the use of the pulmonary artery catheter due to the controversy of not improving the mortality in the patients of the Intensive Care Units, the placement of this catheter has fallen into disuse; however, cardiac output measured by the Swan Ganz catheter remains the «gold standard» for real-time measurement of cardiac output and systemic and pulmonary resistance.

The CO measurement by PAC versus USCOM correlates, in such a way, that USCOM measurement can be used in a patient with septic shock, who is not expected to invade to determine their hemodynamic conditions.

Keywords : Cardiac output; USCOM; thermodilution; Swan-Ganz; pulmonary artery catheter.
