Review Meta Analysis
Incidence of postoperative death and acute kidney injury associated with i.v. 6% hydroxyethyl starch use: systematic review and meta-analysis.
Use of 6% HES solutions in surgical patients is not associated with either harm or benefit in terms of mortality, renal replacement or kidney injury.

Randomized Controlled Trial
Effect of ventilation on cerebral oxygenation in patients undergoing surgery in the beach chair position: a randomized controlled trial.
Surgery in the beach chair position (BCP) may reduce cerebral blood flow and oxygenation, resulting in neurological injuries. The authors tested the hypothesis that a ventilation strategy designed to achieve end-tidal carbon dioxide (E'(CO₂)) values of 40-42 mm Hg would increase cerebral oxygenation (Sct(O₂)) during BCP shoulder surgery compared with a ventilation strategy designed to achieve E'(CO₂) values of 30-32 mm Hg. ⋯ ClinicalTrials.gov NCT01546636.

Randomized Controlled Trial Multicenter Study Observational Study
Association between intraoperative electroencephalographic suppression and postoperative mortality.
Low bispectral index values frequently reflect EEG suppression and have been associated with postoperative mortality. This study investigated whether intraoperative EEG suppression was an independent predictor of 90 day postoperative mortality and explored risk factors for EEG suppression. ⋯ NCT00281489 and NCT00682825.
