“…Our findings are consistent with an observational study, in which general anaesthesia was induced using anaesthetic agents and opioid analgesics increased the PI, but decreased the PVI [14]. These results are similar to those of our recently published article on laparoscopic cholecystectomy [9].…”

Objective: Limited data are available on the use of the perfusion index (PI) and the pleth variability index (PVI) during laparoscopic bariatric surgery. We investigated the effects of pneumoperitoneum and the reverse Trendelenburg position on these indices. Materials and Methods: PI, PVI, heart rate (HR), blood pressure, SpO 2 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 CO 2 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<.001), and a decrease in the PVI (P=.002). The PI and PVI values were not affected during T2 or T3. Pneumoperitoneum caused an increase in mean arterial pressure (MAP) and a decrease in HR. PVI and MAP decreased during T4, but the PI and HR remained unchanged. PVI, HR and MAP increased during T5. Conclusion: Our data suggest that the reverse Trendelenburg position and pneumoperitoneum did not affect the PI or PVI values, whereas deflation decreased the PVI in morbidly obese patients under general anaesthesia.

“…it is an indirect, noninvasive and continuous measure of peripheral perfusion [10]. Previous studies have demonstrated that an increase in PI is an early indicator that general [6][7][8] and epidural anesthesia [11,12] has initiated peripheral vasodilatation.…”

“…It was reported that peripheral perfusion improves during inhalational anesthesia, total intravenous anesthesia [6][7][8], or neuroaxial anesthesia [11,12]. The resulting changes in PI could be useful for monitoring changes in peripheral vasodilatation and sympathetic tone in anesthetized patients, which could reflect the level of analgesia and sedation.…”

“…This regulation is affected by anesthetic agents as most of them cause vasodilatation [6][7][8]. In addition, pain stimuli change the circulating catecholamines level which may be reflected on the tissue perfusion [9].…”

“…This relationship between the pulsatile and the non-pulsatile amounts of blood at any particular site corresponds to PI at that site. It ranges from 0.02% (very weak pulse strength) to 20% (very strong pulse strength) [6][7][8][9][10].…”

Objectives: To evaluate dexmedetomidine as an adjunct drug to propofol for sedation during ERCP, and its effects on perfusion index (PI) which could be used as an indicator for analgesia level.Methods: 76 patients ASA (I-III) scheduled for ERCP procedure were randomly classified to either dexmedetomidine/propofol group or propofol group. In dexmedetomidine/propofol group, sedation was induced by dexmedetomidine (0.7 µg/kg) and propofol (50 mg) followed by infusion of dexmedetomidine (0.4 µg/kg/h) and propofol (0.5-1 mg/kg/h). In propofol group, sedation was induced by propofol (50 mg) followed by propofol infusion (0.5-1 mg/kg/h). HR, SBP, DBP, RR, SPO2 and PI were continuously monitored and recorded at the time points (T0 to T8). Results:Comparing dexmedetomidine/propofol group versus propofol group; PI values showed significant increase at T2 to T7 (p˂0.001), HR values showed significant decrease at T1 to T8 (p 0.013 at T1 and 0.001 at T2 to T8), SBP values showed significant decrease at T1 to T8 (p=0.002 at T1, 0.001 at T2 to T7 and 0.004 at T8) and DBP values showed significant decrease at T4 to T6 (p value 0.008, 0.002 and 0.003 at T4.T5 and T6). RR and SPO 2 values were comparable in both groups. In dexmedetomidine/propofol group, the propofol dosage was significantly lower (p value 0.001) and the recovery time was significantly higher (p value 0.001) than that of propofol group, while the procedure time was comparable between both groups. Dexmedetomidine/propofol group showed higher incidence of bradycardia than propofol group (p value 0.035) while propofol group showed more cases with tachycardia (p value 0.016) and more cases with airway obstruction (p value 0.026).Conclusion: dexmedetomidine is a useful adjunct drug for sedation during ERCP procedure.

Clinical utility of perfusion index (PI) has entered a new realm as a non-invasive, quantitative index of stress response to endotracheal intubation. Transoral robotic surgery (TORS) involves F-K retractor aided docking of the surgical robot producing haemodynamic and stress responses akin to laryngoscopy. We compared the stress response to videolaryngoscopy with that due to docking of da Vinci surgical robot using PI, heart rate and mean arterial pressure evaluated at speci c time points post-laryngoscopy and post-docking. MethodsTwenty-six adult patients, scheduled for TORS under general endotracheal anaesthesia were included in this prospective, observational, single-centric cohort study. Statistical analysis included paired samples ttest, dotted box-whisker plots, trendlines and correlograms for comparative analysis of two stressors, laryngoscopy and docking.Results: PI values at baseline, post-midazolam, 1min and 3min post anaesthetic-induction, laryngoscopy, 1min, 3min and 10min post-laryngoscopy, predocking, docking, 1min, 3min and 10min post-docking were
