Randomized Controlled Trial Comparative Study
Balanced crystalloid compared with balanced colloid solution using a goal-directed haemodynamic algorithm.
Controversy exists regarding the optimal i.v. fluids for use with a goal-directed haemodynamic algorithm. ⋯ Using a goal-directed haemodynamic algorithm to optimize stroke volume, a balanced HES solution is associated with better haemodynamic stability and reduced need for fresh-frozen plasma. There were no signs of renal impairment by colloid solutions when fluid administration is targeted to optimize cardiac preload.

Randomized Controlled Trial Comparative Study
A double-blinded randomized evaluation of alfentanil and morphine vs fentanyl: analgesia and sleep trial (DREAMFAST).
Patients using fentanyl patient-controlled analgesia (PCA), the standard first-line choice in our hospitals, commonly complain of postoperative sleep disruption due to pain. The aim of this study was to determine whether the PCA combination of alfentanil and morphine, which provides longer analgesia without compromising onset speed, would improve postoperative pain-related sleep interference. ⋯ Despite better early postoperative analgesia, pain-related sleep interference was not improved by the PCA combination of alfentanil and morphine.

Ultrasound visual image-guided vs Doppler auditory-assisted radial artery cannulation in infants and small children by non-expert anaesthesiologists: a randomized prospective study.
Cannulation of the radial artery in infants and small children can be challenging, even for the most experienced providers. Utilizing Doppler to aid in radial artery cannulation has been well described. Recent studies have demonstrated the efficacy of ultrasound (US) image-guided vascular access techniques in the paediatric population. The utility of these two techniques, when used by non-expert personnel, has not been studied. ⋯ US-guided radial arterial cannulation in infants and small children provided a greater chance for success at the first attempt compared with the Doppler-assisted technique.

Randomized Controlled Trial
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.

Randomized Controlled Trial
Does warm-up using mental practice improve crisis resource management performance? A simulation study.
Mental practice (MP) is defined as the 'symbolic rehearsal of a physical activity in the absence of any gross-muscular movements' and has been used in sport and music to enhance performance. In healthcare, MP has been demonstrated to improve technical skill performance of surgical residents. However, its effect on crisis resource management (CRM) skills has yet to be determined. We aimed to investigate the effect of warm-up with MP on CRM skill performance during a simulated crisis scenario. ⋯ Unlike technical skills, warm-up with MP does not seem to improve CRM skills in simulated crisis scenarios.
