Summary

This study compares giving norepinephrine continuously versus as needed to prevent low blood pressure during anesthesia in high-risk non-cardiac surgery patients. About 446 adults aged 45 and older with certain risk factors will participate. The goal is to see which method better maintains stable blood pressure.

The number the study aims to enrol. It can still change while the study runs.

Started

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: We will include consenting patients ≥45 years scheduled for elective non-cardiac surgery under general anesthesia with planned continuous intra-arterial blood pressure monitoring with a radial arterial catheter and with at least two of the following risk criteria for developing acute kidney injury: * Age ≥65 years * ASA physical status III or IV * Chronic arterial hypertension * Diabetes mellitus requiring medication * Intra-abdominal surgery * Preoperative renal insufficiency (serum creatinine ≥1.2 mg/dL) Exclusion Criteria: * Pregnancy * Cardiac arrhythmia * History of intracranial hemorrhage or intracranial aneurysm * Clinical indication for continuous norepinephrine infusion during induction of general anesthesia (e.g., severe aortic valve stenosis, coronary artery disease, or heart failure) * Patients who are unable to understand, read, and provide informed consent in German
