Pleth variability index versus pulse pressure variation for intraoperative goal-directed fluid therapy in patients undergoing lowto-moderate risk abdominal surgery: A randomized controlled trial

tailieu.vn

Nevertheless, PVI’s correlation to PPV has been shown to be weak during major abdominal surgery and cardiac surgery, which may be due to intra- operative or chronic changes in arteriolar compliance, sympathetic tone, and heart rate variability [15, 16]. In low-to-moderate risk abdominal surgery, however, such effects on arteriolar and sympathetic tone are probably less frequent and the clinical impact of PVI remains to be determined.

tailieu.vn

Another approach could be the combined use of the vasopressors and different timings, but according to Das et al. reported that women who developed more severe hypotension after SA had greater changes in heart rate variability [29].. In our study, the TEB method was used also as a trend monitor to follow the changes in hemodynamic parameters after SA..

Comparative study of analgesia nociception index (ANI) vs. standard pharmacokinetic pattern for guiding intraoperative fentanyl administration among mastectomy patients

tailieu.vn

ANI is derived from heart rate variability (HRV) analysis—which provides a meas- ure of the effect of respiratory sinus arrhythmia (RSA) on heart rate through the parasympathetic reflex loop. Even though the ideal method for optimizing opioid administration is to follow the pharmacokinetic pattern in order to maintain a serum concentration above the therapeutic level, this method is not practicable.
