Evaluation of the Measurement of Cardiac Output by the NEXFIN HD Monitor in Peroperative

Evaluation of the Measurement of Cardiac Output by the NEXFIN HD Monitor in Peroperative

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.

Inclusion Criteria:

• Adult patients candidate for surgery under general anesthesia requiring oesophageal Doppler or arterial catheter hemodynamic monitoring.

Exclusion Criteria:

• Patients with cardiac and thoracic surgery,
• patients for whom access to the head is impossible,
• facial trauma patients,
• patients with aortic malformation, dilation or coarctation,
• patients with aortic dissection,
• patients with vascular surgery with aortic clamping,
• patients with a tumor, stenosis or varices of the esophagus,
• patients with severe oesophagitis,
• patients with thoracic radiotherapy
• patients under guardianship or curatorship or deprived of liberty.
