Evaluation of pre-induction dynamic arterial elastance as an adjustable predictor of post-induction hypotension: A prospective observational study
Authors' conclusion
In our study, invasive pre-induction Eadyn during deep breathing -could predict post-induction hypotension.
Study context
- Population
- Adults undergoing GA with invasive and non-invasive arterial pressure monitoring
- Participants
- 38 / 38 / 38 / 38
- Exposure
- Invasive vs non-invasive pre-induction Eadyn during tidal and deep breathing for predicting post-induction hypotension
- Invasive Eadyn, deep breathingn = 38
- Invasive Eadyn, tidal breathingn = 38
- Non-invasive Eadyn, deep breathingn = 38
- Non-invasive Eadyn, tidal breathingn = 38
- Outcome
- Prediction of post-induction hypotension
Main finding
As reported in the abstract
| Group | AUC |
|---|---|
| Invasive Eadyn, deep breathing | 0.78 (95% CI 0.61-0.90), P = 0.001 |
| Invasive Eadyn, tidal breathing | 0.66 (95% CI 0.41-0.74), P = 0.095 |
| Non-invasive Eadyn, tidal breathing | 0.66 (95% CI 0.49-0.81), P = 0.096 |
| Non-invasive Eadyn, deep breathing | 0.53 (95% CI 0.36-0.70), P = 0.75 |
