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.

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.
1,003 studies on the registry are indexed under Hypotension; 173 are open to participants now.
This study's planned enrollment of 52 is below the median of 84 across 294 observational studies indexed under Hypotension.

Exclusion Criteria:
Patients with a 30% decrease in SBP from baseline and a decrease in MAP below 65 mmHg in the first 10 minutes after anesthesia induction will be considered to have hypotension.
Other: hypotension
Patients who do not have a 30% decrease from the baseline in SBP and a decrease in MAP below 65 mmHg in the first 10 minutes after anesthesia induction will be considered as not having hypotension.
MAP below 55 mmHg or long-term (2 minutes or more) hypotensive attacks will be treated with ephedrine 0.1mg/kg.
