Study on muscle weakness after surgery in intensive care patients

Official title: Metabolomics Pilot Study on Postoperative Intensive Care Acquired Muscle Weakness (MIRACLE-I Study)

Run by Technical University of Munich · NCT03810768 · Data updated 2026-11-12

This study is testing if changes in blood and muscle samples from surgical patients can help us understand and find markers for muscle weakness that happens after being in intensive care.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are invasive mechanically ventilated critically ill postoperative patients aged 18 and older with an expected ICU stay of more than three days.

Probably not a fit

Patients receiving non-curative care or those classified as moribund may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational pilot trial focuses on surgical patients at high risk for intensive care unit admission. Participants will undergo blood and muscle sample collection at specific time points to analyze metabolic, histological, and molecular changes. The study aims to investigate alterations in the blood metabolome associated with intensive care unit acquired weakness (ICUAW) and to identify potential metabolic markers for this condition.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and potential markers for muscle weakness in critically ill patients, improving patient outcomes.

How similar studies have gone: While this approach is novel, similar studies in metabolomics have shown promise in understanding critical illness-related conditions.
