Few studies have investigated sarcoidosis-related postoperative cardiopulmonary complications, creating a significant knowledge gap. Using a comparative cohort analysis, the authors hypothesized that sarcoidosis would be associated with higher risk for 30-day postoperative pulmonary complications (PPC).</p><h3>Methods</h3><p>This retrospective study examined hospital system data between January 1, 2013, and January 1, 2022, for patients over 18 years, admitted for procedural intervention. 389 sarcoidosis patients and controls (N = 48,823) were identified. The primary endpoint of PPC, as measured by the Agency for Healthcare Research and Quality PPC composite, and secondary endpoints of major adverse cardiovascular events (MACE), PPC subcomposites, and length of stay (LOS) were analyzed.

This risk appears to be independent of disease staging, but is associated with the presence of sarcoidosis features on preoperative chest radiography. Postoperatively, sarcoidosis patients experience longer hospital LOS, suggesting that when complications occur, they are more resource-intensive, when compared to controls. These findings highlight opportunities to enhance preoperative multi-disciplinary optimization, and suggest that tailored perioperative care strategies for sarcoidosis patients would be beneficial.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":100082,"journal":{"name":"Anesthesiology and Perioperative Science","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44254-025-00087-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143475293","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}

Early pediatric data suggest it may offer significant advantages over traditional sedatives, including enhanced predictability, improved safety, and faster recovery times. Despite these promising attributes, its routine use in pediatric populations remains underexplored and unestablished. This narrative review examines remimazolam’s pharmacological properties, including its mechanism of action, metabolism, and elimination, and evaluates its safety and efficacy in pediatric sedation. Potential clinical applications are highlighted, such as procedural sedation, intensive care, and anesthesia induction, with comparisons to conventional agents. While initial studies suggest benefits, critical gaps remain in understanding its use in children. These include age-specific dosing strategies, long-term safety considerations, and its efficacy in children with comorbid conditions or undergoing complex procedures. Addressing these gaps will require robust clinical trials and large-scale observational studies. This review synthesizes current evidence and explores the potential of remimazolam to enhance pediatric sedation and anesthesia practices. By identifying key knowledge gaps and proposing future research directions, it aims to inform clinicians and researchers about the role of remimazolam in improving safety and outcomes in pediatric anesthesia.</p></div>","PeriodicalId":100082,"journal":{"name":"Anesthesiology and Perioperative Science","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44254-025-00090-w.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143404111","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}
