Randomized Controlled Trial
Gradual withdrawal of remifentanil infusion may prevent opioid-induced hyperalgesia.
The aim of this study was to examine if gradual withdrawal of remifentanil infusion prevented opioid-induced hyperalgesia (OIH) as opposed to abrupt withdrawal. OIH duration was also evaluated. ⋯ NCT 01702389. EudraCT number 2011-002734-39.

Multicenter Study Clinical Trial
Effectiveness of platelet inhibition on major adverse cardiac events in non-cardiac surgery after percutaneous coronary intervention: a prospective cohort study.
Platelet inhibition is mandatory therapy after percutaneous coronary intervention (PCI). Withdrawal of oral antiplatelet agents has been linked to increased incidence of postoperative adverse cardiac events in post-PCI patients having non-cardiac surgery (NCS). There is limited knowledge of temporal changes in platelet inhibition in this high-risk surgical population. We therefore performed a multicentre prospective cohort study evaluating perioperative platelet function and its association with postoperative major adverse cardiac events (MACE). ⋯ NCT 01707459 (registered at http://www.clinicaltrials.gov).

Randomized Controlled Trial
Towards individualized perioperative, goal-directed haemodynamic algorithms for patients of advanced age: observations during a randomized controlled trial (NCT01141894).
During a previous study on intraoperative goal-directed haemodynamic treatment (GDHT) in elderly patients, cardiac performance did not improve as anticipated (ClinicalTrials.gov NCT01141894). We hypothesized that in this group, responsiveness to interventions could be predicted by individual patient characteristics. ⋯ NCT01141894.

Review Meta Analysis
Are neuromuscular blocking agents being misused in laboratory pigs?
The literature (2012-4) describing experimental pig surgery was reviewed to estimate the extent to which neuromuscular block (NMB) is used, to examine methods for ensuring unconsciousness, and to identify the rationale for use of NMB and establish the anaesthetist's training. In the first stage of a two-stage review, NMB use was estimated using Web of Knowledge to identify articles describing NMB during pig surgeries. In the second stage, PubMed and Google Scholar were used to increase the number of articles for determining measures taken to prevent accidental awareness during general anaesthesia (AAGA). ⋯ Medical or veterinary anaesthetists supervised anaesthesia in 70% of studies; non-anaesthetists provided NMB, unsupervised, in 23. Nine respondents prioritized experimental expediency over pig welfare. In laboratory pig studies, AAGA may be prevalent; reported details of its attempted prevention are woefully inadequate.
