The glymphatic system, a brain-wide network involved in cerebrospinal fluid circulation and metabolic waste clearance, has been observed to exhibit progressive dysfunction during the development and maintenance of chronic pain. The relationship between chronic pain and glymphatic dysfunction appears multifaceted and complex. This perspective review systematically synthesizes emerging evidence to summarize the potential bidirectional interplay between glymphatic dysfunction and chronic pain pathogenesis, with an emphasis on glymphatic dysfunction as a plausible contributing mediator across diverse pain conditions. We specifically address how neuroinflammation-associated glymphatic dysfunction may contribute to the progression of chronic pain, and conversely, how persistent pain may further amplify neuroinflammation, thereby potentially establishing a self-sustaining vicious cycle. Furthermore, we outline rationales for putative clinical interventions targeting this pathological cascade, with the goal of providing conceptual insights for the development of novel therapeutic strategies for chronic pain. Collectively, this review advances current understanding of the potential links between chronic pain and glymphatic dysfunction and presents an alternative conceptual framework for the future management of chronic pain.</p><h3>Graphic Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":100082,"journal":{"name":"Anesthesiology and Perioperative Science","volume":"4 1","pages":""},"PeriodicalIF":7.5,"publicationDate":"2026-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44254-026-00180-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148281206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These dynamic changes create a heterogeneous perfusion landscape that challenges traditional approaches to oxygen transport assessment. Central venous oxygen saturation (ScvO<sub>2</sub>) has long been used as a surrogate marker of cardiac output and global tissue oxygenation; however, in sepsis, impaired cellular oxygen utilization may result in paradoxically normal or elevated ScvO<sub>2</sub> despite ongoing tissue hypoxia.

We conducted a targeted literature search to identify major international ERAC guidelines and patient-reported outcome measures (PROMs). We then propose and apply an analytical \"Framework for Contextualized ERAC Implementation\" to evaluate this literature. Our analysis reveals that while guidelines from societies like Enhanced Recovery After Surgery (ERAS), Society for Obstetric Anesthesia and Perinatology (SOAP), and National Institute for Health and Care Excellence (NICE) provide robust evidence-based recommendations, their development processes and implicit assumptions often limit direct applicability worldwide. Similarly, PROMs like Obstetric Quality of Recovery (ObsQoR) and Stanford Obstetric Recovery Checklist (STORK), though validated, may not capture recovery domains prioritized in diverse cultural settings, such as those influenced by traditions like zuo yuezi (a traditional period of postpartum confinement and rest in Chinese culture). Successful implementation depends on moving beyond direct translation of protocols to active adaptation across two spectra: resource stratification (from low to high) and cultural integration (from translation to adaptation).

It is characterized by complex clinical manifestations and limited therapeutic efficacy, markedly impairing quality of life. Traditional analgesics often show variable effectiveness, and are associated with significant adverse effects. To address these challenges in pain research, long non-coding RNAs (lncRNAs) have attracted interest due to their key roles in gene transcription, epigenetic regulation, and cellular signaling networks. LncRNAs can modulate multiple structures related to pain, including peripheral nerves, the spinal cord, and higher central nervous system regions, by regulating neuronal excitability, ion channel function, neuroinflammatory responses, glial cell activation, and synaptic plasticity. Notably, they may also participate in central mechanisms underlying the comorbidity of pain and emotional disorders. Nascent intervention strategies targeting lncRNAs, such as antisense oligonucleotides, RNA interference, gene editing, small molecule modulators, and lncRNA replacement therapy, are increasingly demonstrating therapeutic potential. However, constraints on potential clinical translation include limited species conservation of lncRNAs, high tissue and cell specificity, and challenges in delivery efficiency and long-term safety. LncRNAs provide novel molecular insights into NP mechanisms and offer significant opportunities for the development of precise analgesic strategies. Future studies should focus on cross-species validation, targeted delivery system optimization, and integrative mechanistic analyses, to advance clinical translation of lncRNA-based interventions.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":100082,"journal":{"name":"Anesthesiology and Perioperative Science","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44254-026-00172-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
