Study summary

The aim of this study is to compare the postoperative outcome of patients undergoing major liver resection under xenon- compared to desflurane-anesthesia.

Read the detailed description

The aim of this study is to compare the postoperative liver function and additional outcome parameters of patients undergoing major liver resection under xenon- compared to desflurane-anesthesia. Xenon is known to maintain hemodynamic stability and consecutive tissue perfusion. Together with its potential for ischemic pre-conditioning, we hypothesize a protective effect of xenon on post-operative liver failure and ischemia/reperfusion injury.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 29, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
