Perioperative use of opioids: Current controversies and concerns

In the midst of an epidemic of opioid abuse and overdose-related morbidity and mortality, the use of opioids remains the most common means of providing analgesia in the perioperative period.

Furthermore, we describe the role that surgeons and anaesthesiologists can play in reducing perioperative opioid use and mitigate their adverse effects, from both an individual and a population health perspective.
