These gaps disproportionately affect rural and regional hospitals, limiting equitable access to surgery. This commentary outlines how Canada can modernize the anesthesia care team (ACT) model to sustain surgical capacity while maintaining patient safety. Anesthesia assistants (AAs), trained professionals working under anesthesiologist supervision, already support perioperative care in many centres but remain underutilized. Standardizing AA credentials, defining supervision based on case conditions rather than fixed ratios, and implementing transparent safety reporting could expand access responsibly. Surgeons, as procedural leaders whose productivity depends on anesthesia workforce availability, should understand the ACT framework and its safeguards. Strengthening collaboration between surgical and anesthesia leadership offers a practical path to preserve access to surgery and reduce wait times without compromising safety.</p>","PeriodicalId":9573,"journal":{"name":"Canadian Journal of Surgery","volume":"69 4","pages":"E370-E371"},"PeriodicalIF":2.0,"publicationDate":"2026-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13492654/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148757633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although its benefits are established in liver and kidney transplantation, its application to pancreas recovery and clinical islet transplantation is limited. Given the pancreas sensitivity to warm ischemia and the limited functional reserve inherent to islet transplantation, NRP may offer advantages over conventional cold recovery. We report our initial experience utilizing NRP for pancreas recovery in islet transplantation. Islet isolation yielded a high islet mass with excellent viability despite low donor body mass index, a factor traditionally associated with poor yield. Transplantation resulted in rapid improvement in glycemic control, reduced insulin requirements, resolution of hypoglycemia and favourable early graft function. This experience supports further evaluation of NRP to expand pancreas grafts utilization from donation after circulatory arrest and improve islet transplant outcomes.</p>","PeriodicalId":9573,"journal":{"name":"Canadian Journal of Surgery","volume":"69 4","pages":"E316-E318"},"PeriodicalIF":2.0,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13426705/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148583615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
