Clinical Trial Summary

TAPSE, one of the methods for evaluating right ventricular systolic function; It is a bar parameter that can easily measure apex-basal shortening and provides specific information about global RV function. TAPSE/PASP can be calculated as load-independent parameters to evaluate RV function. Because RV function is sensitive to change in afterload, known as the RV-pulmonary circulation (PC) connection.

This study aims to identify patients who are candidates for hypotensive events due to general anesthesia in a hemodynamically stable population.

Description:

TAPSE, one of the methods for evaluating right ventricular systolic function; It is a bar parameter that can easily measure apex-basal shortening and provides specific information about global RV function. TAPSE/PASP can be calculated as load-independent parameters to evaluate RV function. Because RV function is sensitive to change in afterload, known as the RV-pulmonary circulation (PC) connection.

This study aims to identify patients who are candidates for hypotensive events due to general anesthesia in a hemodynamically stable population.

Patients will be measured by transthoracic echocardiography in the preoperative period, 15-30 minutes before induction.

Basal hemodynamic parameters and non-invasive and/or hemodynamic values will be recorded every two minutes after induction until surgical incision.Patients with a 30% decrease in SBP from the baseline and a decrease in MAP below 65 mmHg in the first 10 minutes after anesthesia induction will be considered to have hypotension. Patients will be divided into 2 groups: 'with' and 'without' hypotension.
