Point of care transthoracic echocardiography for the prediction of post – spinal anesthesia hypotension in elderly patients with cardiac diseases and left ventricular dysfunction : Inferior vena cava and post-spinal anesthesia hypotension in elderly patients
Authors' conclusion
The preoperative dIVCmax-to-IVCCI ratio could be a reliable echocardiographic index to predict post - spinal anesthesia hypotension in elderly patients with left ventricular dysfunction.
Study context
- Population
- Elderly orthopedic-trauma patients with cardiac diseases and reduced LV ejection fraction undergoing spinal anesthesia26 with hypotension
- Participants
- 61 patients
- Comparison
- Preoperative TTE indices for predicting post-spinal anesthesia hypotension
- Outcome
- Prediction of post-spinal anesthesia hypotension by echocardiographic indices
Performance
As reported in the abstract
Post-spinal anesthesia hypotension
- Hypotension occurred in 26 of 61 patients
- dIVCmax-to-IVCCI ratio < 48 had greatest performance among echocardiographic indices, with significantly higher diagnostic power than IVCCI > 0.28, fractional area change (FAC) > 42, E/Em ratio < 9 and stroke volume index (SVI) < 32 (ROC analysis)
- Gray zone for dIVCmax-to-IVCCI ratio (40-49) had the lowest number of inconclusive measurements among echocardiographic variables
