About this study
The induction of anesthesia is one of the most critical situations for high-risk-patients undergoing major surgery. For several reasons, it is crucial to maintain adequate blood pressure and cardiac output during this phase.
This observational study aims to find out if the choice of the induction agent has a major impact on blood pressure and the use of antihypotensive drugs during the induction and the surgical procedure in heart-failure patients undergoing the implantation of a left ventricular assist device (LVAD).

Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 19 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
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?
Contact Adrian E Stephan, MD (004962215636107, adrian.stephan@med.uni-heidelberg.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post-Induction hypotension (time frame: First 30 minutes after induction of anesthesia). 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2021; AzTrials last refreshed its copy on 8 Nov 2026.
