Randomized Controlled Trial Multicenter Study Comparative Study
Intravenous versus Volatile Anesthetic Effects on Postoperative Cognition in Elderly Patients Undergoing Laparoscopic Abdominal Surgery.
In patients having laparoscopic abdominal surgery, there was no difference in incidence of delayed neurocognitive recovery between propofol and sevoflurane-based anaesthesia.

The primary goal of this study was to evaluate patterns in acute postoperative pain in a mixed surgical patient cohort with the hypothesis that there would be heterogeneity in these patterns. ⋯ There are multiple distinct acute postoperative pain intensity trajectories, with 63% of patients reporting stable and sustained high or moderate-to-high pain over the first 7 days after surgery. These postoperative pain trajectories were predominantly defined by patient factors and not surgical factors.

Randomized Controlled Trial
Restrictive Transfusion Strategy after Cardiac Surgery.
Recent guidelines on transfusion in cardiac surgery suggest that hemoglobin might not be the only criterion to trigger transfusion. Central venous oxygen saturation (Svo2), which is related to the balance between tissue oxygen delivery and consumption, may help the decision process of transfusion. We designed a randomized study to test whether central Svo2-guided transfusion could reduce transfusion incidence after cardiac surgery. ⋯ A restrictive transfusion strategy adjusted with central Svo2 may allow a significant reduction in the incidence of transfusion.
