Clinical Trial
Subjective cognitive complaints in patients undergoing major non-cardiac surgery: a prospective single centre cohort trial.
Few perioperative studies have assessed subjective cognitive complaint (SCC) in combination with neuropsychological testing. New nomenclature guidelines require both SCC and objective decline on cognitive testing. The objective of our study was to compare SCC and neuropsychological testing in an elderly surgical cohort. ⋯ NCT02650687.

Fentanyl is one of the most frequently administered intraoperative drugs and may increase the risk of postoperative respiratory complications (PRCs). ⋯ NCT03198208.

Review
The prescription opioid crisis: role of the anaesthesiologist in reducing opioid use and misuse.
Why should I care?
Misuse of opioids is a growing global problem, well established in the US and quickly appearing in many high-resource countries. One person dies every 15 minutes in the US from opioid overdose.
For many affected, the perioperative period is the first exposure event. In the US ~6% of previously opioid-naive patients progress to persistent opioid use after surgery.
What can anaesthetists and anesthesiologists do?
- Identify patients at risk of opioid dependence.
- Use multi-modal non-opioid analgesia perioperatively.
- Educate patients on realistic expectations for post-operative pain.
- Consider regional techniques intraoperatively when appropriate.
- Limit discharge prescribing of opioids (42-71% of all postop opioid tablets go unused!).
The bigger picture...
Although inidividual practice changes are important, real impact will come through anesthesiologists as integrators of care (eg. ERAS interventions) and contributions to institutional strategies, patient and provider education.
Take a long view, this problem is not going away in a hurry...
summary -
Multi-injection targeted intracluster injection ultrasound-guided supraclavicular brachial plexus block has been advocated to provide a faster onset of anaesthesia compared with a double injection technique. By placing the needle within clusters of hypoechoic structures, corresponding to neural tissue, this technique may increase needle trauma and the incidence of nerve injury. This study assessed the rate of sub-perineural needle placement with a single intracluster brachial plexus injection in the supraclavicular fossa of human cadavers. ⋯ We observed a high rate of sub-perineural injection with a single intracluster injection. Thus the targeted intracluster injection supraclavicular block cannot be recommended until further evidence is available regarding the safety of this technique.
