Epidural analgesia for postoperative pain: Improving outcomes or adding risks?

Current evidence shows that the benefits of epidural analgesia (EA) are not as impressive as believed in the past, while the risks of adverse effects and serious complications are greater than previously estimated. There are many reasons for the decreasing role of epidural technique in clinical practice (table). Indeed, EA can cause harm and hinder early mobilization in enhanced recovery after surgery (ERAS) programmes. Some ERAS interventions are complex, confusing, sometimes contradictory and apparently unimplementable. In spite of much hype and after almost 25 years, the originator of the concept has described the current status of ERAS as ?far from good?. Outpatient surgery setup has been a remarkable success for many major surgical procedures, and it predates ERAS and appears to be a simpler and better model for reducing postoperative morbidity and hospitalization times. Systematic reviews of comparative studies have shown that less invasive and safer but equally effective alternatives to EA are available for almost all major surgical procedures. These include: paravertebral block, peripheral nerve blocks, catheter wound infusion, periarticular local infiltration analgesia, preperitoneal catheters and transversus abdominis plane block. Increasingly, these non-EA methods are being used as surgeon-delivered regional analgesia (RA) techniques. This encouraging trend of active surgeon participation, with anaesthesiologist collaboration, will undoubtedly improve the decades-old twin problems of underused RA techniques and undertreated postoperative pain. The continued use of EA at any institution can only be justified by results from its own audits; however, regrettably only very few institutions perform such regular audits.

Automated summary

Current evidence suggests that the benefits of epidural analgesia (EA) are not as significant as previously believed, while the risks of adverse effects and serious complications are higher than expected. This has led to a decreasing role of EA in clinical practice, with less invasive and safer alternatives gaining more attention.
