{"title":"Preliminary Experience With Remimazolam for Procedural Sedation and as an Adjunct to General Anesthesia During Diagnostic and Interventional Cardiac Procedures.","authors":"Holly Gillis, Christopher McKee, Kristin Chenault, Marco Corridore, Joseph D Tobias","doi":"10.14740/cr1595","DOIUrl":"10.14740/cr1595","url":null,"abstract":"<p><strong>Background: </strong>Remimazolam is a benzodiazepine which, like midazolam, has sedative, anxiolytic, and amnestic properties. Ester metabolism results in a half-life of 5 - 10 min, a limited context sensitive half-life, and rapid recovery when the infusion is discontinued.</p><p><strong>Methods: </strong>Following the Institutional Review Board (IRB) approval, we performed a retrospective chart review of patients who received remimazolam in the cardiac catheterization, cardiac magnetic resonance imaging (MRI), and electrophysiology suites. The primary objective was to assess efficacy and safety. The secondary objective was to describe bolus and infusion dosing of remimazolam and the need for adjunctive agents to optimize procedural sedation conditions.</p><p><strong>Results: </strong>The study cohort included 26 patients with a median age of 18 years and a total of 33 anesthetic encounters. The most common procedures were endomyocardial biopsy or isolated hemodynamic assessment (right or left heart catheterization). Remimazolam was the primary agent for sedation in 82% of the procedures. The majority of cases (25 encounters, 76%) included a bolus dose of remimazolam prior to the start of an infusion. For those patients who received a starting bolus dose, dosing typically ranged between 30 and 110 µg/kg. Continuous infusion rates of remimazolam varied from 5 to 20 µg/kg/min. No adverse hemodynamic or respiratory effects were noted. Midazolam, fentanyl, and dexmedetomidine were the most frequently used adjunctive agents. One patient required transition to general anesthesia due to the need for a surgical intervention based on the findings of the cardiac catheterization. All other patients were effectively sedated.</p><p><strong>Conclusions: </strong>Our preliminary experience demonstrates that remimazolam effectively provided sedation for diagnostic and therapeutic cardiovascular procedures. Future studies are needed to further define dosing parameters for both bolus dosing and continuous infusion as well as to compare remimazolam to other commonly used for procedural sedation in patients with congenital and acquired heart disease.</p>","PeriodicalId":9424,"journal":{"name":"Cardiology Research","volume":"15 1","pages":"12-17"},"PeriodicalIF":1.9,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10923259/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140093388","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}

{"title":"Partial Pressure of End-Tidal Oxygen and Blood Lactate During Cardiopulmonary Exercise Testing in Healthy Older Participants and Patients at Risk of Cardiac Disease.","authors":"Kazuyuki Kominami, Masatoshi Akino","doi":"10.14740/cr1597","DOIUrl":"10.14740/cr1597","url":null,"abstract":"<p><strong>Background: </strong>The partial pressure of end-tidal oxygen (PETO₂) and end-tidal oxygen concentration (ETO₂) are among the indices that can be measured by exhaled gas analysis. Several observational studies have shown that skeletal muscle function is impaired in patients with cardiac disease; thus, the assessment of skeletal muscle function is important. Additionally, although it has recently been suggested that the difference in PETO₂ from rest to the ventilatory anaerobic threshold (VAT) reflects oxygen availability in peripheral factors, primarily skeletal muscle, the evidence for this is not well established. Therefore, we hypothesized and investigated whether increased blood lactate (BLa) levels, resulting from decreased skeletal muscle and mitochondrial oxygen availability, and PETO₂ dynamics during cardiopulmonary exercise testing (CPET) would be related.</p><p><strong>Methods: </strong>All participants performed the symptomatic limited CPET, and their BLa levels were measured. The difference in PETO₂ and ETO₂ from rest to VAT determined by the V-slope method (ΔPETO₂ and ΔETO₂) was calculated and compared with the increase in BLa due to exercise testing.</p><p><strong>Results: </strong>We recruited 22 healthy older participants (nine males; 69.4 ± 6.8 years) and 11 patients with cardiovascular risk (eight males; 73.0 ± 8.8 years). ΔPETO₂ and ΔETO₂ did not differ between the two groups (P = 0.355 and P = 0.369, respectively), showing no correlation between increase in BLa from rest to VAT, but were significantly correlated with an increase in BLa from rest to the end of exercise (ΔPETO₂, P = 0.030; ΔETO₂, P = 0.029). The correlation was particularly pronounced among those at cardiovascular risk (ΔPETO₂, P = 0.012; ΔETO₂, P = 0.011).</p><p><strong>Conclusions: </strong>ΔPETO₂ and ΔETO₂ from rest to VAT during CPET may be useful as indices reflecting skeletal muscle oxygen utilization capacity.</p>","PeriodicalId":9424,"journal":{"name":"Cardiology Research","volume":"15 1","pages":"29-36"},"PeriodicalIF":1.9,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10923256/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140093387","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}
