Personalized perioperative pain management: a narrative review

Perioperative pain management has shifted from standardized, procedure-based protocols toward individualized, patient-centered approaches. Inadequate pain control can result in short-term adverse outcomes, including delayed ambulation, prolonged hospitalization, and increased complications, as well as long-term sequelae such as chronic persistent postsurgical pain. Early models of preemptive and preventive analgesia emphasized pain relief primarily through the use of opioids. Growing concern about opioid-related adverse effects established the basis for multimodal and opioid-sparing strategies. Nevertheless, with the onset of the global opioid crisis, heightened awareness of the risks of opioid overuse has fueled interest in opioid-free techniques. However, evidence does not demonstrate that opioid-free methods are superior to opioid-sparing approaches. This underscores the importance of returning to the central goals of enhanced recovery after surgery: early restoration of function and reduction of complications. Within this framework, personalized pain management has emerged as a practical paradigm that tailors interventions to individual characteristics, including comorbidities, psychological status, pain sensitivity, and recovery objectives. This review outlines the rationale, current practices, and future directions of personalized perioperative pain management and proposes a framework for integrating new strategies into clinical care.
