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.

Heterogeneity among the primary studies included in a systematic review (SR) is one of the most challenging considerations for systematic reviewers. Current practices in anaesthesiology SRs have not been evaluated, but traditional methods may not provide sufficient information to evaluate the true nature of these differences. We address these issues by examining the practices for evaluating heterogeneity in anesthesiology reviews. ⋯ Subgroup analysis was used in 59% Cochrane reviews, while sensitivity analysis was used in 62%. Many reviews did not provide sufficient detail regarding heterogeneity. We are calling for improvement to reporting practices.

Meta Analysis
Benefit and harm of pregabalin in acute pain treatment: a systematic review with meta-analyses and trial sequential analyses.
Pregabalin has demonstrated anti-hyperalgesic properties and was introduced into acute pain treatment in 2001. Our aim was to evaluate the beneficial and harmful effects of pregabalin in postoperative pain management. We included randomized clinical trials investigating perioperative pregabalin treatment in adult surgical patients. ⋯ Based on trials with low risk of bias, pregabalin may have a minimal opioid-sparing effect, but the risk of SAEs seems increased. However, the GRADE-rated evaluations showed only moderate to very low quality of evidence. Consequently, a routine use of pregabalin for postoperative pain treatment cannot be recommended.

Review Meta Analysis
Tissue Doppler assessment of diastolic function and relationship with mortality in critically ill septic patients: a systematic review and meta-analysis.
Myocardial dysfunction may contribute to circulatory failure in sepsis. There is growing evidence of an association between left ventricular diastolic dysfunction (LVDD) and mortality in septic patients. Utilizing echocardiography, we know that tissue Doppler imaging (TDI) variables e' and E/e' are reliable predictors of LVDD and are useful measurements to estimate left ventricular (LV) filling pressures. ⋯ There is a strong association between both lower e' and higher E/e' and mortality in septic patients.

Review Meta Analysis Comparative Study
Efficacy of perineural vs systemic dexamethasone to prolong analgesia after peripheral nerve block: a systematic review and meta-analysis.
Perineural dexamethasone has gained popularity in regional anaesthesia to prolong the duration of analgesia, but its advantage over systemic administration is disputed. The objective of this meta-analysis was to compare the analgesic efficacy of both routes of administration during peripheral nerve block. The methodology followed the PRISMA statement guidelines. ⋯ Glucose concentrations were not increased when dexamethasone was injected systemically, but this outcome was reported by only two trials. There is, therefore, moderate evidence that perineural dexamethasone combined with bupivacaine, but not ropivacaine, slightly prolongs the duration of analgesia, without an impact on other pain-related outcomes, when compared with systemic dexamethasone. Injection of perineural dexamethasone should be cautiously balanced in light of the off-label indication for this route of administration.
