ABSTRACT
Resumo Fundamento A endocardite infecciosa (EI) refere-se à infecção da superfície endocárdica do coração e geralmente ocorre em valvas nativas ou protéticas. Objetivo Este estudo teve como objetivo levantar dados de EI refletindo a terapêutica cirúrgica, em um Hospital Universitário do interior do estado de São Paulo - Brasil. Método Abordagem retrospectiva e observacional de 328 pacientes com EI operados entre 1982 e 2020 Resultados Os principais dados (n=121/37%), insuficiência cardíaca congestiva (n=114/35%), valvopatia (n=92/28%), diabetes mellitus (n=85/26%), doença renal crônica (n=59/18%) e febre reumática (49/15%). A insuficiência renal é um dos principais e mais relevantes fatores de risco pré-cirúrgicos para um mau prognóstico. Conclusão Para um melhor resultado clínico e cirúrgico é necessário o diagnóstico sindrômico e etiológico precoce da EI, principalmente em pacientes com múltiplas comorbidades.
Abstract Background Infectious endocarditis (IE) refers to infection of the endocardial surface of the heart and usually occurs in native or prosthetic valves. Objective This study aimed to raise IE data reflecting the surgical therapy in a University Hospital in the interior of the State of Sao Paulo-Brazil. Method Retrospective and observational approach of 328 patients with IE who underwent surgery between 1982 and 2020 Results The main data (n=121/37%), congestive heart failure (n=114/35%), valve disease (n=92/28%), diabetes mellitus (n=85/26%), chronic kidney disease (n=59/18%), and rheumatic fever (49/15%). Renal failure is one of the main and most relevant pre-surgical risk factors for a poor prognosis. Conclusion For a better clinical and surgical outcome, an early syndromic and etiological diagnosis of IE is necessary, especially in patients with multiple comorbidities.
ABSTRACT
Abstract Introduction: There are many reasons to believe that the nitric oxide/guanosine 3'5' - cyclic monophosphate (or NO/cGMP) pathway on vasoplegic states is underestimated. To study indigo carmine (IC) as an alternative to methylene blue was the investigation rationale. Methods: The IC (3mg/kg intravenous infusion) study protocol included five experimental groups; 1) Control group — saline was injected at 0 and 10 minutes; 2) IC group — IC was injected at 0 and saline at 10 minutes; 3) compound 48/80 (C48/80) group — C48/80 was injected at 0 minute and saline at 10 minutes; 4) C48/80 + IC group — C48/80 was injected at 0 minute and IC at 10 minutes; and 5) IC + C48/80 group — IC was injected at 0 minute and C48/80 at 10 minutes. The studies were carried out by registering and measuring hemodynamic and blood gasometric parameters, including continuous cardiac output. Results: 1) The effects of the drugs (IC and C48/80) were more evident in the first 20 minutes of recording; 2) hypotensive responses were more pronounced in the C48/80 groups; 3) IC isolated or applied before C48/80 caused transient pulmonary hypertension; and 4) after the first 20 minutes, the pressure responses showed stability with apparent hypotension more pronounced in the C48/80 groups. Clinical observations showed significant hemodynamic instability and catastrophic anaphylactic reactions (agitation, pulmonary hypertension, severe bronchospasm, urticaria, high-intensity cyanosis, violent gastric hypersecretion, and ascites). Conclusion: A global results analysis showed differences between groups only in the first 20 minutes of the experiments.
ABSTRACT
Abstract Traumatic left ventricular pseudoaneurysms are rare and surgical correction is the treatment of choice. In this article, it is reported a case of a myocardial stab injury with primary suture and development of a giant pseudoaneurysm, five years later, that underwent surgical repair.
