Randomized Controlled Trial Comparative Study
Comparison of propofol and fentanyl administered at the end of anaesthesia for prevention of emergence agitation after sevoflurane anaesthesia in children.
Propofol 1 mg/kg reduces emergence delirium in children, without increasing nausea, vomiting or length of PACU stay, unlike fentanyl 1 mcg/kg.

In patients receiving an infusion of norepinephrine, the relationship between the amplitude of the oximeter plethysmographic waveform and stroke volume may be variable and quality of the waveform might be reduced, compared with patients not receiving norepinephrine. We assessed the reliability of the pleth variability index (PVI), an automatic measurement of the respiratory variation of the plethysmographic waveform, for predicting fluid responsiveness in patients receiving norepinephrine infusions. ⋯ PVI was less reliable than PPV and SVV for predicting fluid responsiveness in critically ill patients receiving norepinephrine. In addition, PVI could not be measured in a significant proportion of patients. This suggests that PVI is not useful in patients receiving norepinephrine.

Intraoperative tissue oxygenation and postoperative outcomes after major non-cardiac surgery: an observational study.
The relationship between tissue oxygen saturation (StO(2)) and serious postoperative complications remains unclear. We tested the hypothesis that perioperative in patients undergoing major non-cardiac surgery is inversely related to serious surgical outcomes. ⋯ Minimum perioperative peripheral tissue oxygenation predicted a composite of major complications and mortality from major non-cardiac surgery. This is an observational association and whether clinical interventions to augment tissue oxygenation will improve outcomes remains to be determined.
