NCT06765551

Brief Summary

The aim of this observational case-control study is to investigate, whether artificial intelligence can detect ultrasound-derived imaging characteristics typical for intensive care unit-acquired weakness. The main questions it aims to answer are:

  1. 1.Is the evaluation of specific parameters of neuromuscular ultrasound using AI-based image analysis suitable for detecting and monitoring critically ill ICU patients with ICUAW?
  2. 2.Do the results of AI-based ultrasound image analysis correlate with:

Sampling MethodNon-Probability Sample
Study Population

All patients with critical illness fulfilling the inclusion criteria should be screened for the study on two surgical ICUs at the department of anesthesiology and intensive care medicine of Jena University Hospital, Germany.

You may qualify if:

  • Patients aged 18 years or above
  • Major elective surgery, e.g. cardiothoracic or abdominal surgery
  • Expected ICU stay \>1 day postoperatively
  • Healthy, age-machted subjects without ICUAW (recruited from staff of the department of anesthesiology and intensive care medicine)

You may not qualify if:

  • No informed consent
  • Emergency surgery
  • Previous participation in the same study
  • Preexisting neuromuscular disease
  • Preexisting central nervous system disease with residual neuromuscular impairment (e.g. cerebral haemorrhage, stroke, brain tumor)
  • High-dose glucocorticoid therapy (\>300 mg hydrocortisone or equivalent per day) before or during particiation in the study
