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...

Randomized Controlled Trial
Reduced perioperative blood loss in children undergoing craniosynostosis surgery using prolonged tranexamic acid infusion: a randomised trial.
Tranexamic acid (TXA) reduces intraoperative blood loss and transfusion during paediatric craniosynostosis surgery. Additional reduction of postoperative blood loss may further reduce exposure to allogeneic blood products. We studied the effect of combined intra- and postoperative TXA treatment on postoperative blood loss in children. ⋯ Combined intra- and postoperative tranexamic acid treatment reduced postoperative and overall blood loss and transfusion requirements. Improved clot stability represents a possible mechanism for blood loss reduction.

The marked increase in mis-use of prescription opioids has greatly affected our society. One potential solution is to develop improved analgesics which have agonist action at both mu opioid peptide (MOP) and nociceptin/orphanin FQ peptide (NOP) receptors. BU10038 is a recently identified bifunctional MOP/NOP partial agonist. The aim of this study was to determine the functional profile of systemic or spinal delivery of BU10038 in primates after acute and chronic administration. ⋯ These in vivo findings demonstrate the translational potential of bifunctional MOP/NOP receptor agonists such as BU10038 as a safe, non-addictive analgesic with fewer side-effects in primates. This study strongly supports that bifunctional MOP/NOP agonists may provide improved analgesics and an alternative solution for the ongoing prescription opioid crisis.
