Quantitative visualization of gastrointestinal motility in critically ill patients using a non-invasive single-channel electro amplifier: A prospective observational cohort feasibility study
Authors' conclusion
EGG/EEnG could enable quantitative visualization of GI motor function in critically ill patients.
Study context
- Population
- Critically ill patients with mechanical ventilation54 analysed
- Participants
- 54 vs 50
- Exposure
- Critically ill patients vs healthy controls (previous study); Electrogastrography (EGG)/EEnG pre- vs post-prandial
- Critically illn = 54
- Controlsn = 50reference
- Outcome
- Feasibility of EGG/EEnG to quantitatively visualize gastrointestinal (GI) motor function (dominant frequency (DF), dominant power (DP), PR)
Methodological details41 of 54 analysed patients on enteral nutrition; age and BMI differed from controls

| Gastric log10 DP, pre- vs post-prandial, controlsSignificant increase | 3.22 vs 3.04 | P = 0.009 |
| Small intestinal log10 DP, pre- vs post-prandial, critically ill patientsNo significant difference | 1.52 vs 1.45 | P = 0.181 |
| Small intestinal log10 DP, pre- vs post-prandial, controlsSignificant increase | 1.86 vs 1.70 | P < 0.001 |
