This study evaluates the efficacy of methylene blue (MB) with blood transfusion (BT) as a potential rescue therapy in acute severe bleeding in pigs.Methods: Thirty animals were randomly assigned to one of six groups following the induction of fixed-pressure hemorrhagic shock, after reaching a mean arterial pressure (MAP) of 55 mmHg - Group 1 (60 BT: BT after 60 minutes), Group 2 (60 MB: MB infusion after 60 minutes), Group 3 (60 MB + BT: MB and BT after 60 minutes), Group 4 (15 MB + BT: MB and BT after 15 minutes), Group 5 (15 BT + 60 MB: BT after 15 minutes and MB infusion after 60 minutes), and Group 6 (15 MB + 60 BT: MB infusion after 15 minutes and BT after 60 minutes). Hemodynamic and blood gas parameters were meticulously recorded, reversal of the shock was considered when MAP reached 90% of the baseline MAP.Results: Except for Group 2, all groups reverted from the shock. However, groups that received MB in combination with BT, specifically Groups 3 and 4, exhibited statistically significant higher ratios of maximum MAP to baseline MAP.Conclusion: Using MB concomitant with BT allowed the reversal of hemorrhagic shock with higher median arterial pressure levels compared to BT alone or applying MB separately from BT. This suggests that simultaneous application of MB and BT could be a more effective strategy for reversing the effects of severe acute bleeding.","PeriodicalId":72457,"journal":{"name":"Brazilian journal of cardiovascular surgery","volume":"e20230480 e20230480","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11488389/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142482250","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}

Therefore, this study aims to analyze and compare the preservation of human aneurysmatic aortic tissues in three different solutions.Methods: Six human abdominal aortic aneurysms were obtained from patients after surgical ablation. The aorta samples were incubated in different solutions - 0.9% normal physiological saline solution, Ringer's lactate solution, and histidine-tryptophan-ketoglutarate solution (Custodiol®). Segments were collected at 0, 6, 24, and 48 hours. Creatine kinase and nitrate/nitrite were quantified for each incubation time. The tissue's alpha-smooth muscle actin was analyzed by immunofluorescence.Results: There was a significant increase in creatine kinase formation in the normal saline group at 0 and 48 hours and in the Ringer's lactate group at 0 and 48 hours (P=0.018 and P=0.028). The lower levels of creatine kinase and nitrate/nitrite and the aortic tissues' morphological integrity show that histidine-tryptophan-ketoglutarate has better tissue protection. These data suggest that histidine-tryptophan-ketoglutarate induces a protective effect on smooth muscle cells, with less tissue depletion in the aortic aneurysm.Conclusion: This study compared three preservation solutions with the potential for human abdominal aortic aneurysm tissue preservation. The histidine-tryptophan-ketoglutarate solution reduced tissue injury and improved tissue preservation in human abdominal aortic aneurysm tissue samples.","PeriodicalId":72457,"journal":{"name":"Brazilian journal of cardiovascular surgery","volume":"e20230434 e20230434","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11488392/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142482247","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}

This study aims to determine the association of lactate with early mortality and postoperative morbidity.Methods: This is a prospective cohort study carried out in the Department of Cardiovascular and Thoracic Surgery, King George's Medical University (India), from January 2020 to December 2022. A total of 270 patients were included in this study. Serum lactate levels were measured preoperatively, intraoperatively on-pump, coming off-pump, and at six, 12, 24, and 48 hours postoperatively.Results: Early mortality was noted in 17 cases (6.3%). While both lactate and lactate clearance correlated with duration of mechanical ventilation, vasopressor duration, and intensive care unit and hospital stay, correlation with early mortality was noted only with lactate at 24 hours. Logistic regression analysis demonstrated that lactate levels at preoperative period (adjusted odds ratio [OR] 4.76 [1.67-13.59], P=0.004) and at 24 hours after bypass (OR 1.21 [1.00-1.47], P=0.046) and vasopressor duration (OR 1.11 [1.04-1.19], P=0.002) are independent predictors of mortality. Receiver operating characteristic curve analysis showed that arterial lactate on-pump, off-pump, and at six, 12, and 24 hours after surgery had significant area under the curve for predicting mortality.Conclusion: Arterial lactate and lactate clearance show good correlation with duration of mechanical ventilation, vasopressor support, and intensive care unit and hospital stay and can serve as a good indicator to guide therapeutic decisions in postoperative period. However, it fails to be a sensitive predictor of mortality.","PeriodicalId":72457,"journal":{"name":"Brazilian journal of cardiovascular surgery","volume":"e20230245 e20230245","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11488391/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142482245","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}

It can present with variable clinical presentations, ranging from incidental findings to hemodynamic instability. Here, we described two cases of fragmented sternal wire migration to the right ventricle.Methods: Retrospective review of the clinical course of two patients presenting with a fragmented sternal wire embedded in the right ventricle after sternotomy for cardiovascular surgery. We also conducted a literature review to identify similar cases, compared them based on reported clinical variables, and discussed the role of diagnostic imaging and management.Results: We identified 13 patients (11 from the literature), of which 85% were men, and the median age was 64 years; 46% presented with hemorrhagic shock, another 46% had other cardiovascular symptoms, and 8% were asymptomatic. The presentation was bimodal, 54% presented within three weeks of the original sternotomy, while 46% had sternotomy more than a year before. Sternal dehiscence/instability was observed in 61% of cases. Computed tomography scan was the most common diagnostic modality (54%). Two patients did not undergo surgery, and two others died after surgery, while others had a successful surgical repair.Conclusion: Migration of a fragmented sternal wire is a phenomenon presented on a dehisced and unstable sternum that can occur days or years after sternotomy. These findings and the associated cardiac injury can be easily missed on computed tomography scan reporting if one is not looking for it. After diagnosis, treatment should be individualized according to the patient's needs.","PeriodicalId":72457,"journal":{"name":"Brazilian journal of cardiovascular surgery","volume":"e20230461 e20230461","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11488393/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142482248","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}
