Comparative efficacy of finger versus forehead Plethysmographic Variability Index monitoring in pediatric surgical patients
Authors' conclusion
Although forehead and finger Plethysmographic Variability Index monitoring were similarly sensitive in predicting fluid responsiveness in pediatric surgical patients, the former method provided higher specificity. The best cut-off value for PVI measurements with forehead and finger probes was found to be 14%.
Study context
- Population
- Mechanically ventilated pediatric patients undergoing minor elective surgery; fluid responsiveness = ≥ 15% increase in CO after passive leg raise
- Participants
- 50 participants
- Comparison
- Finger vs Forehead
- Outcome
- Perfusion index measured at the finger or forehead and PVI monitoring; ability to predict fluid responsiveness
