Imagine having surgery and the pain never fully leaves. This condition, called chronic post-surgical pain, is a real and debilitating problem for some patients. A new review of medical literature looked at what might help prevent it. The analysis suggests that for certain complex surgeries, using regional anesthesia—like targeted nerve blocks—could be a key part of preventing pain from becoming chronic. The review also highlights that using specific non-opioid medications around the time of surgery might help patients avoid getting stuck on opioid painkillers long-term. It's important to know this isn't a new study with fresh data, but a synthesis of what existing research has shown. The authors didn't report specific numbers on how much these approaches help or any safety issues. They conclude that preventing long-term pain requires a personalized plan before surgery, one that uses these targeted pain control methods. The takeaway is that the tools might already exist in the anesthesia toolkit to make a real difference for patients at high risk.

Key Takeaway
Consider narrative review findings on regional anesthesia and non-opioids for CPSP/COU as a synthesis needing confirmation by primary data.
A narrative mini-review synthesized evidence from various study types, including RCTs and systematic reviews, on perioperative interventions for chronic post-surgical pain (CPSP) and postoperative chronic opioid use (COU). The review did not report a specific study population, sample size, setting, or comparator. It concluded that evidence supports the use of regional anesthesia (e.g., neuroaxial or paravertebral blocks) for CPSP prevention in high-risk procedures and that targeted systemic non-opioids may help mitigate opioid consumption and chronicity. No specific effect sizes, absolute numbers, or statistical significance measures were reported for these interventions.
Safety and tolerability data for the interventions were not reported in the review. The authors propose that managing CPSP and COU requires a precision medicine approach with thorough preoperative risk stratification and implementation of targeted, mechanism-based perioperative analgesia.
Key limitations stem from the review's design. As a narrative synthesis, it does not provide new primary data or report specific quantitative outcomes. The evidence strength for the supported interventions cannot be assessed from the provided summary. Practice relevance is restrained; the review suggests a framework for perioperative care but does not offer specific, measurable guidance on intervention efficacy.

Chronic Post-Surgical Pain (CPSP) and Postoperative Chronic Opioid Use (COU) pose significant public health challenges. Anesthesiologists play a vital role in modulating acute pain during surgery and influencing its chronic trajectory. CPSP is defined as pain persisting for ≥3 months, localized to the surgical field or relevant nerve territory, and with other causes excluded. COU, a surrogate marker for prolonged utilization, is defined as prolonged utilization (≥10 prescriptions or ≥120 days’ supply) in the postsurgical year, excluding the initial 90 postoperative days. This mini-review synthesizes evidence on perioperative risk factors, mechanistic pathways, and anesthetic/analgesic interventions to influence the development of CPSP and COU.
We performed a narrative literature review (February 2000–December 2025) across PubMed and Google Scholar, focusing on risk factors and mitigation strategies for CPSP and COU. Key search terms included “CPSP,” “COU,” “multimodal analgesia,” “neuroinflammation,” “epigenetic changes,” “TIVA,” and “precision medicine.” The search prioritized randomized controlled trials, systematic reviews, and key preclinical studies.
Chronicity is highly predictable based on preoperative psychosocial factors (e.g., anxiety, catastrophizing) and phenotypic hyperalgesia. Key mechanisms include central sensitization, neuroinflammation, epigenetic molecular programming, and gut-brain axis disruption. Evidence supports regional anesthesia (e.g., neuroaxial/paravertebral blocks) for CPSP prevention in high-risk procedures and targeted systemic non-opioids to mitigate opioid consumption and chronicity.
CPSP and COU require a precision medicine approach that accounts for individual variability. This necessitates thorough preoperative risk stratification and the implementation of targeted, mechanism-based perioperative analgesia to intercept the neurobiological programming underlying chronic pain and opioid dependence.
