p-value: p=<0.05
In patients under combined epidural and general anesthesia, pneumoperitoneum decreases perfusion index without changing plethysmographic variability index, suggesting these indices must be interpreted cautiously during laparoscopy.
Wajima et al. (2017) conducted an observational in Laparoscopic gastrointestinal surgery (n=20). Pneumoperitoneum vs. Baseline (pre-pneumoperitoneum) was evaluated on Changes in perfusion index (PI) and pleth variability index (PVI) (p=<0.05). In patients receiving combined epidural and general anesthesia, pneumoperitoneum significantly decreased perfusion index but did not change pleth variability index.
