The QoR-15 is a patient-reported outcome questionnaire that measures the quality of recovery after surgery and anaesthesia. We aimed to perform a systematic review and meta-analysis of the measurement properties of the QoR-15. ⋯ The QoR-15 fulfils requirements for outcome measurement instruments in clinical trials and is the first measurement instrument of postoperative quality of recovery to undergo a systematic review according to the COSMIN checklist.

Randomized Controlled Trial
Prevention of arterial hypotension after spinal anaesthesia using vena cava ultrasound to guide fluid management.
Significant hypotension is frequent after spinal anaesthesia and fluid administration as therapy is usually empirical. Inferior vena cava (IVC) ultrasound (US) is effective to assess fluid responsiveness in critical care patients. The aim of this study was to evaluate the IVCUS-guided volume optimization to prevent post-spinal hypotension. ⋯ www.clinicaltrials.gov - NCT02271477.

Many hospitals, and medical and dental clinics and offices, routinely monitor their procedural-sedation practices-tracking adverse events, outcomes, and efficacy in order to optimize the sedation delivery and practice. Currently, there exist substantial differences between settings in the content, collection, definition, and interpretation of such sedation outcomes, with resulting widespread reporting variation. ⋯ This tool is amenable for inclusion in either a paper or an electronic medical record. An additional, parallel research tool is presented to promote consistency and standardized data collection for procedural-sedation investigations.

Observational Study
Prognostic value of postoperative high-sensitivity troponin T in patients with different stages of kidney disease undergoing noncardiac surgery.
Emerging evidence suggests that postoperative troponin release is a strong and independent predictor of short-term mortality. However, evaluating elevated troponins in patients with chronic kidney disease (CKD) is still controversial and is often disregarded. This study examines morbidity along with short- and long-term mortality risk associated with elevated high-sensitivity troponin T (hsTnT) in patients with different stages CKD undergoing noncardiac surgery. ⋯ Elevated postoperative hsTnT is associated with a dose-dependent increase in 30-day and long-term mortality risk in each stage of CKD with an estimated glomerular filtration rate ≥30 ml min-1 1.73 m-2.

The main defence against bacterial infection is oxidative killing by neutrophils, which requires molecular oxygen in wounded tissues. High inspired-oxygen fractions increase tissue oxygenation. But, whether improving tissue oxygenation actually reduces surgical-site infection (SSI) remains controversial. We therefore tested the primary hypothesis that supplemental oxygen (80% vs 30%) reduces the risk of a 30-day composite of deep tissue or organ-space SSI, healing-related wound complications, and mortality. ⋯ NCT01777568.
