Randomized Controlled Trial Multicenter Study
Multicentre, prospective, double-blind, randomised controlled clinical trial comparing different non-opioid analgesic combinations with morphine for postoperative analgesia: the OCTOPUS study.
Head-to-head comparisons of combinations of more than one non-opioid analgesic (NOA) with morphine alone, for postoperative analgesia, are lacking. The objective of this multicentre, randomised, double-blind controlled trial was to compare the morphine-sparing effects of different combinations of three NOAs-paracetamol (P), nefopam (N), and ketoprofen (K)-for postoperative analgesia. ⋯ EudraCT: 2012-004219-30; NCT01882530.

Review Meta Analysis
Evidence of opioid-induced hyperalgesia in clinical populations after chronic opioid exposure: a systematic review and meta-analysis.
Opioid-induced hyperalgesia (OIH) is well documented in preclinical studies, but findings of clinical studies are less consistent. The objective was to undertake a systematic review and meta-analysis of studies examining evidence for OIH in humans after opioid exposure. ⋯ OIH was evident in patients after chronic opioid exposure, but findings were dependent upon pain modality and assessment measures. Further studies should consider evaluating both pain threshold and pain tolerance across a range of modalities to ensure assessment validity. Significant subgroup findings suggest that potential confounders of pain judgements, such as illicit substance use, affective characteristics, or coping styles, should be rigorously controlled in future studies.

Randomized Controlled Trial Multicenter Study Comparative Study
Satisfactory analgesia with minimal emesis in day surgeries: a randomised controlled trial of morphine versus hydromorphone.
Opioids remain the mainstay therapy for post-surgical pain. Although both morphine and hydromorphone are potent analgesics, it has been suggested that hydromorphone is clinically better. Our primary objective was to compare morphine with hydromorphone for achieving satisfactory analgesia with minimal emesis (SAME). ⋯ NCT02223377.

Randomized Controlled Trial Multicenter Study
Importance of intraoperative oliguria during major abdominal surgery: findings of the Restrictive Versus Liberal Fluid Therapy in Major Abdominal Surgery trial.
The association between intraoperative oliguria during major abdominal surgery and the subsequent development of postoperative acute kidney injury (AKI) remains poorly defined. We hypothesised that, in such patients, intraoperative oliguria would be an independent predictor of subsequent AKI. ⋯ NCT01424150.

Observational Study
Preadmission chronic opioid usage and its association with 90-day mortality in critically ill patients: a retrospective cohort study.
The aim of this study was to investigate the association of chronic opioid usage with 90-day mortality in critically ill patients after admission to the ICU. ⋯ Our results suggest that in a cohort of critically ill adult patients, chronic opioid use is associated with an increase in 90-day mortality. This association was more evident in cancer patients and non-CKD patients.
