[Position statement: surgery and diabetes mellitus (Update 2023)]. / Positionspapier: Operation und Diabetes mellitus (Update 2023).

This position statement reflects the perspective of the Austrian Diabetes Association concerning the perioperative management of people with diabetes mellitus based on the available scientific evidence. The paper covers necessary preoperative examinations from an internal/diabetological point of view as well as the perioperative metabolic control by means of oral antihyperglycemic and/or insulin therapy.

New Diabetic Medication Sodium-Glucose Cotransporter-2 Inhibitors Can Induce Euglycemic Ketoacidosis and Mimic Surgical Diseases: A Case Report and Review of Literature.

Background: Euglycemic diabetic ketoacidosis (EDKA) is a potentially life-threatening condition and a reported side effect of antidiabetic sodium-glucose-cotransporter-2-inhibitors (SGLT2-I). The analysis of the herein presented case and its management formed the incentive to prepare this multidisciplinary work and includes an overview about perioperative SGLT2-I-induced ketoacidosis. Method: A PubMed search on relevant entries was conducted combining the terms "euglycemic diabetic ketoacidosis" AND "surgery." Results: A total of 33 articles on SGLT2-I-induced ketoacidosis in the context of surgical treatment were identified. According to this literature research risk factors for the development are infection, perioperative fasting, surgical stress, and insulin dose reduction. Conclusion: Unspecific symptoms mimicking acute abdomen and normoglycemia can lead to delayed diagnosis of EDKA and might harm patients under SGLT2-I therapy in the perioperative setting. SGLT2-I medication should be withheld for at least 24-48 h prior to surgery according to this review of literature and restarted only in stable clinical conditions to avoid the severe complication of EDKA.

Real-World Analysis of Therapeutic Outcome in Type 1 Diabetes Mellitus at a Tertiary Care Center.

Insulin replacement in type 1 diabetes mellitus (T1DM) needs intensified treatment, which can either be performed by multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII). This retrospective analysis of a real-world scenario aimed to evaluate whether glycaemic and cardiovascular risk factors could be controlled with CSII outclass MDI as suggested by recent evidence. Data from patients with either insulin pump (n=68) or injection (n=224) therapy at an Austrian tertiary care centre were analysed between January 2016 and December 2017. There were no significant differences with regard to the latest glycosylated hemoglobin, cardiovascular risk factor control or diabetes-associated late complications. Hypoglycaemia was less frequent (P<0.001), sensor-augmented therapy was more common (P=0.003) and mean body mass index (BMI) was higher (P=0.002) with CSII treatment. This retrospective analysis of real-world data in T1DM did not demonstrate the superiority of insulin pump treatment with regard to glycaemic control or cardiovascular risk factor control.

Acute viral myositis: profound rhabdomyolysis without acute kidney injury.

BACKGROUND: Acute viral myositis (AVM) may be triggered by influenza A/B, enteroviruses and other viruses. Severe complications including rhabdomyolysis regularly lead to acute kidney injury (AKI). The aim of this short report was to discuss management and differential diagnosis of massive creatine kinase (CK) elevation. PATIENT, MATERIAL AND METHODS: Herein, we report on a 19-year-old Austrian male of African descent with a history of respiratory tract infections and whole-body pain. He further developed acute viral myositis and massive CK elevation up to 440,000 IU/L but without any signs of AKI. A literature search relating AVM, management and differential diagnosis of rhabdomyolysis was conducted in PubMed and UptoDate. RESULTS: A full panel of serological and autoimmune blood work-up including testing for human immunodeficiency virus (HIV), hepatitis, influenza A/B, Epstein-Barr virus (EBV), antinuclear antibodies (ANA) and autoantibodies against various extractable nuclear antigens (ENA) did not reveal evidence for viral originators or autoimmune diseases. This case indicates that in acute viral myositis associated with extreme CK elevation (>400,000 IU/L) AKI might be completely absent. Potential causes for this clinical phenotype, differential diagnosis and management are discussed.

[Anesthesiological perspectives on perioperative management in continuous subcutaneous insulin infusion (CSII): stop or continue?] / Anästhesiologische Perspektive zum perioperativen Management bei kontinuierlicher subkutaner Insulininfusion (CSII): Stoppen oder fortführen?

OBJECTIVE: Perioperative handling of insulin pumps (CSII) is inconsistent. The aims of this study were a literature search addressing this clinical question, analysis of data found and a proposal for perioperative management recommendations for clinical practice. METHODS: A systematic search was conducted in PubMed and Clinical Research Network. RESULTS AND DISCUSSION: A total of 11 publications on CSII in perioperative medicine were identified. According to the evidence CSII guarantees perioperative glycemic stability under certain clinical situations. The use of CSII could be continued in patients undergoing elective non-cardiac minor surgery with fasting for up to one meal only. International guidelines on surgery in diabetes do not address the use of perioperative CSII. There is no nationwide register data for CSII, the use of which could be around 18%. Based on the search results, a hospital internal protocol for perioperative management with CSII and patient information material were designed. CONCLUSION: Growing evidence for improved patient outcome with perioperative CSII usage warrants interdisciplinary transfer of knowledge and experiences on intensified insulin therapy and patient empowerment.

New Hemostatic Agents: Perioperative Anesthetic Considerations.

AIM: Pharmacologic agents with procoagulant effects and antidotes against antithrombotic drugs play an important role in the prevention and management of perioperative coagulopathic bleeding. The aim of this narrative review is knowledge transfer from new and renewed hemostatic agents to anesthesiologists and other physicians involved in perioperative medicine. METHODS: The literature search was performed on PubMed and the Summaries of Product Characteristics of 6 pharmacologic agents of interest: fibrinogen concentrate, vonicog alfa, susoctocog alfa, idarucizumab, andexanet alfa, and argatroban. RESULTS AND DISCUSSION: This review highlights renewed interest in fibrinogen concentrate, an old prohemostatic drug, in correcting hypofibrinogenemia which is a leading pathomechanism of perioperative bleeding. This review describes clinically relevant aspects for brand new recombinant prohemostatic drugs for their use in critical clinical situations: vonicog alfa for the prevention and correction of bleeding in von Willebrand syndrome, and susoctocog alfa in acquired hemophilia A. Clinical experience and increasing evidence broadened the field of applications of the old antithrombotic drug argatroban to heparin resistance. New antidotes against new antithrombotic agents revolutionized the safety of chronic antithrombotic therapy in the emergency situations of acute and trauma surgery. Information on dosing and handling of new hemostatic drugs is summarized. CONCLUSION: New and potent hemostatic agents exist for perioperative use and may enrich the armamentarium of anesthesiologists. Implementation into clinical practice requires their availability and user knowledge. Sustainability of these new drugs depends on post-licensing research, cost-effectiveness, and clinical experience.

Normal values for Doppler echocardiographic assessment of prosthetic valve function after transcatheter aortic valve replacement: a systematic review and meta-analysis.

Transcatheter aortic valve replacement has emerged as valuable treatment modality for patients with severe aortic stenosis and an unacceptable risk/benefit ratio for open heart surgery, but particularities specific to TAVR and a rapidly growing number of available TAVR prosthesis make post-procedural assessment of valve function challenging. Aim of the present analysis was to collect and pool all available data currently in the literature regarding normal doppler values for transcatheter prosthetic heart valves and to provide a comprehensive overview. A PRISMA checklist-guided systematic review and meta-analysis of prospective observational studies or national and device specific registries or randomized clinical trials was conducted. Studies were identified by searching PUBMED, SCOPUS, Cochrane Central Register of Controlled Trials and LILACs from January 2000 to March 2017. Out of 240 abstracts, 155 studies reporting echocardiographic parameter for twelve different valves prosthesis in a total of 27,159 patients were in included in this meta-analysis. The means and standard deviations of peak velocity, peak gradient, mean gradient and effective orifice were extracted and pooled from the included studies. The pooled means and standard deviations for all available TAVR prosthesis were classified according to implanted valve size and time since implantation. The present study firstly describes a pooled analysis of normal values for all available TAVR prosthesis in order to empower treating physicians with a reliable tool to perform follow-up echocardiographic assessment in TAVR patients and to safely identify patients with prostheses dysfunction.
