Pleth variability index and fluid management practices: a multicenter service evaluation

Patrice Forget et al. BMC Res Notes. .

Abstract

Objectives: The introduction of a new technology has the potential to modify clinical practices, especially if easy to use, reliable and non-invasive. This observational before/after multicenter service evaluation compares fluid management practices during surgery (with fluids volumes as primary outcome), and clinical outcomes (secondary outcomes) before and after the introduction of the Pleth Variability Index (PVI), a non-invasive fluid responsiveness monitoring.

Results: In five centers, 23 anesthesiologists participated during a 2-years period. Eighty-eight procedures were included. Median fluid volumes infused during surgery were similar before and after PVI introduction (respectively, 1000 ml [interquartile range 25-75 [750-1700] and 1000 ml [750-2000]). The follow-up was complete for 60 from these and outcomes were similar. No detectable change in the fluid management was observed after the introduction of a new technology in low to moderate risk surgery. These results suggest that the introduction of a new technology should be associated with an implementation strategy if it is intended to be associated with changes in clinical practice.

Relationship between complication rate, fluid volume administered during surgery. Hypo- (on the left of the U-curve) as well as hypervolemia (on the right) may be associated with postoperative complications. Fluid management associated with optimal cardiac output (green curve) may correlate with the lower rate of perioperative complications
