Cardiac Output, Peroperative
Conditions
Brief summary
Continuous perioperative cardiac output (DC) and blood pressure (PA) monitoring contributes to hemodynamic stability and ensures adequate perfusion pressure, resulting in a reduction in morbidity and mortality and length of hospital stay. The monitors usually used in perioperative are either semi-invasive and difficult for calibration (oesophageal Doppler) or invasive (arterial catheter). The Nexfin HD allows these two measurements and it is completely non-invasive, remains to validate its use in peroperative.
Interventions
DEVICEIntraoperative heart rate measurement (reference method)
Measurement of cardiac output by both monitors: NEXFIN HD and oesophageal doppler, blood pressure measurement by the catheter and NEXFIN HD monitor, and cardiac output and blood pressure measurements after treatment administration (vasoconstrictor or filling)
