Materials and Methods: PI, PVI, heart rate (HR), blood pressure, SpO2 and ventilation parameters were recorded before anaesthesia induction (T0), 5 min after endotracheal intubation (T1), immediately before surgery, after the patient had been in the reverse Trendelenburg position for 5 min (T2), after inflating the abdomen with CO2 in reverse Trendelenburg (T3), after the abdomen had been deflated (T4) and 5 min after extubation (T5).Results: General anaesthesia induced an increase in the PI (P
📌 3 Key Takeaways
🎯
Objective & Hypothesis:Objective: Limited data are available on the use of the perfusion index (PI) and the pleth variability index (PVI) during laparoscopic bariatric surgery.
📊
Key Findings & Data:We investigated the effects of pneumoperitoneum and the reverse Trendelenburg position on these indices.
💡
Conclusion & Impact:Materials and Methods: PI, PVI, heart rate (HR), blood pressure, SpO2 and ventilation parameters were recorded before anaesthesia induction (T0), 5 min after endotracheal intubation (T1), immediately before surgery, after the patient had been in the reverse Trendelenburg position for 5 min (T2), after inflating the abdomen with CO2 in reverse Trendelenburg (T3), after the abdomen had been deflated (T4) and 5 min after extubation (T5).Results: General anaesthesia induced an increase in the PI (P
