Thoracic impedance pneumography in propofol-sedated patients undergoing percutaneous endoscopic gastrostomy (PEG) placement in gastrointestinal endoscopy: A prospective, randomized trial
Primary result · Hypoxic episodesResult — go to the resultOdds ratio 0.47Authors' conclusion
Additional thoracic impedance pneumography reduced the quantity and extent of hypoxic events with less need of assisted ventilation.
Study context
- Population
- Patients undergoing PEG placement under propofol sedation by gastroenterologists or trained nurses; mostly oncological indication, ASA II–III
- Participants
- 173 patients
- Comparison
- Additional thoracic impedance pneumography vs standard monitoring
- Primary endpoint
- Hypoxic episodes (SpO2 < 90% for >15 s)

| Outcome | TIM | SM | P value |
|---|---|---|---|
| Minimal SpO2 per procedure | 90.0% ± 8.9 | 84.0% ± 17.6 | P = 0.007 |
| Adjustments of oxygen flowSignificantly more often necessary in SM | P = 0.034 |
