About this study
Official title: Prediction of TAPSE/PASP Ratio for Hypotension Due to General Anesthesia Induction in Pulmonary Resection Surgery
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.

Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
echocardiography (time frame: 30 minute). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
