Resumo Fundamento Análises em grandes registros apontam desfechos desfavoráveis para mulheres submetidas à cirurgia de revascularização do miocárdio (CRM), enquanto estudos randomizados sofrem com a falta de representatividade. Objetivo Comparar os resultados hospitalares ajustados entre homens e mulheres submetidos à CRM. Métodos Entre julho de 2017 e junho de 2019, 3991 pacientes foram submetidos à CRM primária isolada, tanto de forma eletiva como de urgência, em 5 hospitais de estado de São Paulo, Brasil. Para equilibrar as diferenças entre homens e mulheres, as populações foram ajustadas utilizando o Propensity Score Matching. Os desfechos considerados para análise foram os utilizados pelo STS Adult Database. As análises foram conduzidas no software R, considerando significância valores de p < 0,05. Resultados Após o Propensity Score Matching (1:1), cada grupo incluiu 1089 pacientes. Em relação às variáveis intraoperatórias os homens apresentaram maior tempo de CEC (p<0,001), tempo cirúrgico (p<0,001), número de anastomoses distais (p<0,001) e uso de enxertos arteriais. Em relação aos desfechos as mulheres apresentaram maior incidência de infecção de ferida profunda (p=0,006), tempo prolongado na Unidade de Terapia Intensiva (p=0,002), maior necessidade do uso de balão intraórtico (p=0,04), maior taxa de transfusão sanguínea (p<0,001), maior readmissão hospitalar em até 30 dias após a cirurgia (p=0,002) e maior taxa de óbitos (p=0,03). Conclusões Apesar dos homens terem apresentado um maior tempo de CEC, maior número de enxertos arteriais e maior número de anastomoses distais, os resultados imediatos após CRM foram piores em mulheres.

Abstract Background Analyses of extensive registries indicate adverse outcomes for women undergoing coronary artery bypass grafting (CABG) surgery, while randomized studies often lack representativeness. Objective To compare adjusted hospital outcomes between men and women undergoing CABG. Methods From July 2017 to June 2019, 3991 patients underwent primary isolated CABG, both electively and urgently, in 5 hospitals in the state of São Paulo, Brazil. To mitigate demographic differences between men and women, populations were adjusted using propensity score matching (PSM). The outcomes considered for analysis were those used by the STS Adult Database. The analyses were performed using R software, with a significance set at p<0.05. Results After PSM (1:1), each group included 1089 patients. Regarding intraoperative variables, men exhibited longer cardiopulmonary bypass (CPB) time (p<0.001), surgical time (p<0.001), a higher number of distal anastomoses (p<0.001), and increased use of arterial grafts. Regarding outcomes, women had a higher incidence of deep sternal wound infection (p=0.006), prolonged Intensive Care Unit stay (p=0.002), increased need for an intra-aortic balloon pump (p=0.04), higher blood transfusion rates (p<0.001), higher 30-day hospital readmission rates after surgery (p=0.002) and higher mortality rate (p=0.03). Conclusions Although men had longer CPB times, a greater number of arterial grafts, and a greater number of distal anastomoses, immediate results after CABG were poorer in women.

ABSTRACT Introduction: Along with cardiopulmonary bypass time, aortic cross-clamping time is directly related to the risk of complications after heart surgery. The influence of the time difference between cardiopulmonary bypass and cross-clamping times (TDC-C) remains poorly understood. Objective: To assess the impact of cardiopulmonary bypass time in relation to cross-clamping time on immediate results after coronary artery bypass grafting in the Registro Paulista de Cirurgia Cardiovascular (REPLICCAR) II. Methods: Analysis of 3,090 patients included in REPLICCAR II database was performed. The Society of Thoracic Surgeons outcomes were evaluated (mortality, kidney failure, deep wound infection, reoperation, cerebrovascular accident, and prolonged ventilation time). A cutoff point was adopted, from which the increase of this difference would affect each outcome. Results: After a cutoff point determination, all patients were divided into Group 1 (cardiopulmonary bypass time < 140 min., TDC-C < 30 min.), Group 2 (cardiopulmonary bypass time < 140 min., TDC-C > 30 min.), Group 3 (cardiopulmonary bypass time > 140 min., TDC-C < 30 min.), and Group 4 (cardiopulmonary bypass time > 140 min., TDC-C > 30 min.). After univariate logistic regression, Group 2 showed significant association with reoperation (odds ratio: 1.64, 95% confidence interval: 1.01-2.66), stroke (odds ratio: 3.85, 95% confidence interval: 1.99-7.63), kidney failure (odds ratio: 1.90, 95% confidence interval: 1.32-2.74), and in-hospital mortality (odds ratio: 2.17, 95% confidence interval: 1.30-3.60). Conclusion: TDC-C serves as a predictive factor for complications following coronary artery bypass grafting. We strongly recommend that future studies incorporate this metric to improve the prediction of complications.

Resumo Fundamento: A identificação de fatores de riscos na cirurgia cardiovascular auxilia na previsibilidade resultando na otimização de desfechos e redução de custos. Objetivo: Identificação dos preditores de risco pré e intraoperatórios para internação prolongada após cirurgia de revascularização do miocárdio (CRM) no Estado de São Paulo. Métodos: Análise transversal no banco de dados REPLICCAR II, registro prospectivo, consecutivo, multicêntrico que incluiu cirurgias de revascularização miocárdica realizadas entre agosto de 2017 e julho de 2019. O desfecho principal foi o tempo de internação prolongado, definida como período de pós-operatório superior a 14 (quatorze) dias. Para a identificação dos preditores foram realizadas análises de regressão logística uni- e multivariada. Os valores de p menores de 0,05 foram considerados significativos. Resultados: A mediana de idade foi de 63 (57-70) anos e 26,55% eram do sexo feminino. Dos 3703 pacientes analisados, 228 (6,16%) apresentaram longa permanência hospitalar (LPH) após a CRM e a mediana da internação foi de 17 (16-20) dias. Foram preditores da LPH após a CRM: idade >60 anos (OR 2,05; IC95% 1,43 - 2,87; p<0,001); insuficiência renal (OR 1,73; IC95% 1,29 - 2,32; p<0,001) e transfusão de hemácias no intraoperatório (OR 1,32; IC 1,07 - 2,06; p=0,01). Conclusão: Nesta análise, a idade > 60 anos, insuficiência renal e a transfusão de hemácias no intraoperatório foram preditores independentes de LPH após a CRM. A identificação destas variáveis pode ajudar no planejamento estratégico multiprofissional visando melhoria de resultados e otimização de recursos no estado de São Paulo.

Abstract Background: Identifying risk factors in cardiovascular surgery assists in predictability, resulting in optimization of outcomes and cost reduction. Objective: This study aimed to identify preoperative and intraoperative risk predictors for prolonged hospitalization after coronary artery bypass grafting (CABG) surgery in the state of São Paulo, Brazil. Methods: A cross-sectional analysis using data from the REPLICCAR II database, a prospective, consecutive, multicenter registry that included CABG surgeries performed between August 2017 and July 2019. The primary outcome was a prolonged hospital stay (PHS), defined as a postoperative period exceeding 14 days. Univariate and multivariate logistic regression analyses were performed to identify the predictors with significance set at p <0.05. Results: The median age was 63 (57-70) years and 26.55% of patients were female. Among the 3703 patients analyzed, 228 (6.16%) had a PHS after CABG, with a median hospital stay of 17 (16-20) days. Predictors of PHS after CABG included age >60 years (OR 2.05; 95% CI 1.43-2.87; p<0.001); renal failure (OR 1.73; 95% CI 1.29-2.32; p <0.001) and intraoperative red blood cell transfusion (OR 1.32; 95% CI 1.07-2.06; p=0.01). Conclusion: Age >60 years, renal failure, and intraoperative red blood cell transfusion were independent predictors of PHS after CABG. The identification of these variables can help in multiprofessional strategic planning aimed to enhance results and resource utilization in the state of São Paulo.

ABSTRACT Introduction: Atrial fibrillation is the main complication in the postoperative period of cardiovascular surgery. Its genesis is multifactorial, so its rapid identification to mitigate the associated risks is essential. Objective: To evaluate the incidence of atrial fibrillation in patients undergoing coronary artery bypass grafting (CABG) and its relationship with other complications in our setting. Methods: This is a multicenter, observational study involving patients undergoing isolated CABG between 2017 and 2019 with data from the Registro Paulista de Cirurgia Cardiovascular (or REPLICCAR II). Variables were prospectively collected in REDCap following the definitions given by version 2.73 of the Society of Thoracic Surgeons Adult Cardiac Surgery Database. Data were collected with prior authorization from the local ethics committee and analyses performed in R software. Results: A total of 3,803 patients were included, of these 605 had postoperative atrial fibrillation (POAF). In order to adjust the groups, propensity score matching was used. Such analyses resulted in 605 patients in each group (without POAF vs. with POAF). Among patients with POAF, the mean age was 67.56 years, with a prevalence of males (73.6%, 445 patients). Patients belonging to the group with POAF had a mortality rate of 9.26% (P=0.007), longer ventilation time (P<0.001), pneumonia (P<0.001), and sepsis (P<0.001). In multiple analysis, acute renal dysfunction (P=0.032) and longer intensive care unit stay (P<0,001) were associated with the presence of POAF. Conclusion: POAF in CABG is associated with longer intensive care unit and hospital stay, as well as renal dysfunction, pneumonia, and in-hospital mortality.

Abstract This study investigated the spatial distribution, parasite interactions, and affinities of Branchiura parasites according to macrohabitat and surface type on fish from the Araguari River, Amapá State, in the Brazilian Amazon. This study presents novel information on the interactions of branchiuran species with host fish, and how the morphology of their attachment structures is associated with different host surface morphologies, with and without scales. A total of 558 fish specimens of 26 species were collected, of which 109 fish (10 species) were parasitized by at least one branchiuran parasite; these were selected for further study. The parasites were collected from the buccal cavity, gills, fins, and integument of the host fish. Parasites with suction discs (Argulus) were mainly associated to hosts with small scales and no scales, while parasites with hooks (Dolops) were mainly associated to hosts with large scales. Overall, parasites with suction discs were more specialized per site than those with hooks. distribution River State Amazon morphologies 55 2 10 (1 cavity gills fins Argulus (Argulus Dolops (Dolops Overall 5 1 (

Abstract Background The short-term results after using arterial grafts still raise questions and doubts for medical society. Objective To compare the immediate outcomes of patients undergoing single arterial graft versus multiple arterial grafts coronary artery bypass grafting surgery. Methods Cross-sectional cohort study in the São Paulo Registry of Cardiovascular Surgery II (REPLICCAR II). Perioperative data from 3122 patients were grouped by the number of arterial grafts used, and their outcomes were compared: reoperation, deep sternal wound infection (DSWI), stroke, acute kidney injury, prolonged intubation (>24 hours), short hospital stay (<6 days), prolonged hospital stay (>14 days), morbidity and mortality. Propensity Score Matching (PSM) matched 1062 patients, adjusted for the mortality risk. Results After PSM, the single arterial graft group showed patients with advanced age, more former smokers, hypertension, diabetes, stable angina, and previous myocardial infarction. In the multiple arterial grafts, there was a predominance of males, recent pneumonia, and urgent surgeries. After the procedure, there was a higher incidence of pleural effusion (p=0.042), pneumonia (p=0.01), reintubation (p=0.006), DSWI (p=0.007), and sternal debridement (p=0.015) in the multiple arterial grafts group, however, less need for blood transfusion (p=0.005), extremity infections (p=0.002) and shorter hospital stays (p=0.036). Bilateral use of the internal thoracic artery was not related to increased DSWI rate, but glycosylated hemoglobin >6.40% (p=0.048). Conclusion Patients undergoing the multiarterial technique had a higher incidence of pulmonary complications, and DSWI, where glycosylated hemoglobin ≥6.40%, had a greater influence on the infectious outcome than the choice of grafts. shortterm term society surgery Crosssectional Cross sectional REPLICCAR II. .

Resumo Fundamento Os resultados a curto prazo após o uso de enxertos arteriais ainda suscitam questionamentos e dúvidas na sociedade médica. Objetivo Comparar os resultados imediatos de pacientes submetidos à cirurgia de revascularização do miocárdio com enxerto arterial único versus enxertos arteriais múltiplos. Métodos Estudo de coorte transversal no Registro Paulista de Cirurgia Cardiovascular II (REPLICCAR II). Os dados perioperatórios de 3122 pacientes foram agrupados pelo número de enxertos arteriais utilizados e seus desfechos foram comparados: reoperação, infecção profunda da ferida torácica (IPFT), acidente vascular cerebral, lesão renal aguda, intubação prolongada (>24 horas), tempo de internação curta (<6 dias), tempo de internação prolongada (>14 dias), morbidade e mortalidade. O Propensity Score Matching (PSM) correspondeu a 1062 pacientes, ajustado para o risco de mortalidade. Resultados Após PSM, o grupo enxerto arterial único apresentou pacientes com idade avançada, mais ex-fumantes, hipertensos, diabéticos, portadores de angina estável e infarto do miocárdio prévio. Nos enxertos arteriais múltiplos houve predomínio do sexo masculino, pneumonia recente e cirurgias de urgência. Após o procedimento, houve maior incidência de derrame pleural (p=0,042), pneumonia (p=0,01), reintubação (p=0,006), IPFT (p=0,007) e desbridamento esternal (p=0,015) no grupo de enxertos multiarteriais, porém, menor necessidade de hemotransfusão (p=0,005), infecções de extremidades (p=0,002) e menor tempo de internação (p=0,036).

Abstract A new species of Rineloricaria is described from the Iguaçu, Magé, Saracuruna, Guapiaçu, Macacu, Macaé, and Paraíba do Sul River basins in southeastern Brazil based on morphological and molecular data. The new species is diagnosed among congeners by the combination of the following characters: absence of plates in most of the ventral surface of pectoral girdle; snout tip with elliptical naked area reaching posteriorly the anteriormost pore of the infraorbital ramus of sensory canal; dorsal-fin spinelet present; supraoccipital and predorsal plates with smooth keels; five series of lateral plates below the dorsal fin; median and mid-ventral series of plates with well-developed keels. The new species is distinguished from congeners that inhabit the rivers draining the Serra do Mar in Rio de Janeiro state by the partial plate coverage of the ventral surface of the pectoral girdle and the abdomen (vs. pectoral girdle and abdomen completely covered by plates in Rineloricaria nigricauda, R. steindachneri, and R. zawadzkii). The new species shares the absence of plates on the abdominal surface with other species from the Paraná, Uruguay, and other Brazilian coastal river basins.

ABSTRACT Introduction: Deep sternal wound infections (DSWI) are so serious and costly that hospital services continue to strive to control and prevent these outcomes. Microcosting is the more accurate approach in economic healthcare evaluation, but there are no studies in this field applying this method to compare DSWI after isolated coronary artery bypass grafting (CABG). This study aims to evaluate the incremental risk-adjusted costs of DSWI on isolated CABG. Methods: This is a retrospective, single-center observational cohort study with a propensity score matching for infected and non-infected patients to compare incremental risk-adjusted costs between groups. Data to homogeneity sample was obtained from a multicentric database, REPLICCAR II, and additional sources of information about costs were achieved with the electronic hospital system (Si3). Inflation variation and dollar quotation in the study period were corrected using the General Market Price Index. Groups were compared using analysis of variance, and multiple linear regression was performed to evaluate the cost drivers related to the event. Results: As expected, infections were costly; deep infection increased the costs by 152% and mediastinitis by 188%. Groups differed among hospital stay, exams, medications, and multidisciplinary labor, and hospital stay costs were the most critical cost driver. Conclusion: In summary, our results demonstrate the incremental costs of a detailed microcosting evaluation of infections on CABG patients in São Paulo, Brazil. Hospital stay was an important cost driver identified, demonstrating the importance of evaluating patients’ characteristics and managing risks for a faster, safer, and more effective discharge.

ABSTRACT Objective To describe the clinical, bronchoscopic, diagnostic, and therapeutic aspects between children and adults. Methods This retrospective study compared the clinical and bronchoscopic characteristics of adults and children who underwent bronchoscopy for suspected foreign body aspiration. Data on sex, outpatient or emergency origin, bronchoscopy results, characteristics of the aspirated foreign body, and complications were analyzed. Results In total, 108 patients were included in the analysis, with foreign body aspiration diagnosed in 69% of patients (30 children and 44 adults). In 91% of patients, there was a clinical history suggestive of aspiration. The mean age of the adults was 65.89 (±19.75) years, and that of the children was 2.28 (±1.78) years. Most of the children were under 3 years of age (80%), while adults were mostly 70 years of age or older (54.5%). Emergency care was more common among children than adults. The most common foreign bodies found in both age groups were organic bodies, primarily seeds. The most frequent locations of foreign bodies were the lobar bronchi in adults and the main bronchi in children. Flexible bronchoscopy is the primary method for diagnosis and treatment. Transient hypoxemia occurred particularly frequently in children (5%). Conclusion Foreign body aspiration, particularly that involving seeds, is more common in the extremes of age. A clinical history suggestive of aspiration is crucial in determining the need for bronchoscopy, which should be performed as early as possible. Flexible bronchoscopy is an effective and safe diagnostic technique. sex origin results analyzed total 10 analysis 69 30 (3 4 . adults) 91 6589 65 89 65.8 ±19.75 1975 19 75 (±19.75 228 2 28 2.2 ±1.78 178 1 78 (±1.78 80%, 80 80% , (80%) 7 54.5%. 545 54.5% 54 5 (54.5%) seeds treatment 5%. 5% (5%) possible technique 6 ( 9 658 8 65. ±19.7 197 (±19.7 22 2. ±1.7 17 (±1.7 (80% 54.5 (54.5% (5% ±19.

Abstract Introduction: Anemia and blood transfusion are risk factors for morbidity/mortality in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). The objective of this study is to analyze the association of blood transfusion with morbidity/mortality in patients undergoing coronary artery bypass grafting (CABG) under CPB in the state of São Paulo, Brazil. Methods: This is a retrospective analysis using the State of São Paulo Registry of Cardiovascular Surgery from November 2013 to August 2014. Blood transfusion was only considered during surgery or within six hours after surgery. Anemia was defined as hematocrit ≤ 37.5%. Patients < 18 years old were excluded. The sample was divided in four groups - Group I (851, no anemia), Group II (200, anemia without blood transfusion), Group III (181, no anemia and transfusion), and Group IV (258, anemia and transfusion). Results: A total of 1,490 patients were included; 639 (42.9%) were anemic and 439 (29.5%) underwent blood transfusion. Group II showed lower composite morbidity (odds ratio [OR] −0.05; confidence interval [CI] −0.27-0.17; P=0.81) than Group III (OR 0.41; CI 0.23-0.59; P=0.018) or Group IV (OR 0.54; CI 0.31-0.77; P=0.016). Group III was at greater risk of mortality (OR 0.73; CI 0.43-1.03; P=0.02) than Group II, which was exposed only to anemia (OR −0.13; CI −0.55-0.29; P=0.75), or Group IV (OR 0.29; CI −0.13-0.71; P=0.539). Conclusion: Anemia in patients undergoing CABG with CPB is bad, but blood transfusion can be worse, increasing at least 50% the risk for mortality and/or morbidity.

Resumo Fundamento Resultados prévios com o uso de circulação extracorpórea (CEC) geram dificuldades na escolha do melhor tratamento para cada paciente na cirurgia de revascularização miocárdica (CRM) no contexto atual. Objetivo Avaliar o impacto da CEC no cenário atual da CRM no estado de São Paulo. Métodos Foram analisados 2.905 pacientes submetidos à CRM de forma consecutiva em 11 centros do estado de São Paulo pertencentes ao Registro Paulista de Cirurgia Cardiovascular (REPLICCAR) I. Dados perioperatórios e de seguimento foram colocados via on-line por especialistas treinados e capacitados em cada hospital. Foram analisadas as associações das variáveis perioperatórias com o tipo de procedimento (com ou sem CEC) e com os desfechos. A mortalidade esperada foi calculada por meio do EuroSCORE II (ESII). Os valores de p menores de 5% foram considerados significativos. Resultados Não houve diferença significativa em relação à idade dos pacientes entre os grupos (p=0,081). Dentre os pacientes, 72,9% eram de sexo masculino; 542 pacientes foram operados sem CEC (18,7%). Das características pré-operatórias, pacientes com infarto agudo do miocárdio (IAM) prévio (p=0,005) e disfunção ventricular (p=0,031) foram operados com CEC; no entanto, pacientes de emergência ou em classe funcional New York Heart Association (NYHA) IV foram operados sem CEC (p<0,001). O valor do ESII foi semelhante para ambos os grupos (p=0,427). Na CRM sem CEC, houve preferência pelo uso do enxerto radial (p<0,001) e com CEC pela artéria mamária direita (p<0,001). No pós-operatório, o uso de CEC esteve associado com reoperação por sangramento (p=0,012). Conclusão Atualmente, no REPLICCAR, reoperação por sangramento foi o único desfecho associado ao uso da CEC na CRM. (Arq Bras Cardiol. 2020; 115(4):595-601)

Abstract Background Previous results on the use of cardiopulmonary bypass (CPB) have generated difficulties in choosing the best treatment for each patient undergoing myocardial revascularization surgery (CABG) in the current context. Objective Evaluate the current impact of CPB in CABG in São Paulo State. Methods A total of 2905 patients who underwent CABG were consecutively analyzed in 11 São Paulo State centers belonging to the São Paulo Registry of Cardiovascular Surgery (REPLICCAR) I. Perioperative and follow-up data were included online by trained specialists in each hospital. Associations of the perioperative variables with the type of procedure and with the outcomes were analyzed. The study outcomes were morbidity and operative mortality. The expected mortality was calculated using EuroSCORE II (ESII). The values of p <5% were considered significant. Results There were no significant differences concerning the patients’ age between the groups (p=0.081). 72.9% of the patients were males. Of the patients, 542 underwent surgery without CPB (18.7%). Of the preoperative characteristics, patients with previous myocardial infarction (p=0.005) and ventricular dysfunction (p=0.031) underwent surgery with CPB. However, emergency or New York Heart Association (NYHA) class IV patients underwent surgery without CPB (p<0.001). The ESII value was similar in both groups (p=0.427). In CABG without CPB, the radial graft was preferred (p<0.001), and in CABG with CPB the right mammary artery was the preferred one (p<0.001). In the postoperative period, CPB use was associated with reoperation for bleeding (p=0.012). Conclusion Currently in the REPLICCAR, reoperation for bleeding was the only outcome associated with the use of CPB in CABG. (Arq Bras Cardiol. 2020; 115(4):595-601)

Resumo Fundamento: O desafio atual da cirurgia cardiovascular (CCV) é melhorar resultados em pacientes cada vez mais graves. Nesse sentido, Programas de Melhoria Contínua da Qualidade (PMCQ) tem impactado os resultados. Objetivo: Avaliar a evolução da incidência e mortalidade das CCV, assim como os resultados atuais do Instituto do Coração do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (InCor). Métodos: Análise dos resultados das CCV realizadas no InCor entre jan-1984 e jun-2019. Foram observadas as tendências dos volumes cirúrgicos e da mortalidade em 5 períodos 1º (1984-1989), 2º (1990-1999), 3º (2000-2007), 4º (2008-2015) e 5º (2016-2019). O PMCQ foi estabelecido entre 2015-2016. A análise incluiu o total de cirurgias e a evolução dos procedimentos mais frequentes. Resultados: Foram realizadas 105.599 CCV, com uma média anual de 2.964 procedimentos e mortalidade de 5,63%. Comparando o 4º com o 5º período, o volume global médio de cirurgias foi de 2.943 para 3.139 (p = 0,368), cirurgias de revascularização miocárdica (CRM) de 638 para 597 (p = 0,214), valvas cardíacas de 372 para 465 (p = 0,201) e cardiopatias congênitas de 530 para 615 (p = 0,125). A mortalidade média global passou de 7,8% para 5% (p < 0,0001), nas cirurgias de revascularização miocárdica de 5,8% para 3,1% (p < 0,0001), nas cirurgias valvares de 14% para 7,5% (p < 0,0001) e nas cirurgias de cardiopatias congênitas de 12,1% para 9,6% (p < 0,0001). Conclusão: Embora haja uma tendência recente ao aumento dos volumes cirúrgicos, houve uma diminuição significativa da mortalidade cirúrgica nos grupos analisados. Após o estabelecimento do PMCQ, as taxas de mortalidade se aproximaram a dos padrões internacionais.

Abstract Background: The current challenge of cardiovascular surgery (CVS) is to improve the outcomes in increasingly severe patients. In this respect, continuous quality improvement (CQI) programs have had an impact on outcomes. Objective: To assess the evolution of the incidence and mortality due to CVS, as well as the current outcomes of the Hospital das Clínicas Heart Institute of the University of São Paulo Medical School (InCor-HCFMUSP). Methods: An outcome analysis of CVSs performed at the InCor, between January 1984 and June 2019. We observed the surgical volume and mortality rates in 5 time periods: 1st (1984-1989), 2nd (1990-1999), 3rd (2000-2007), 4th (2008-2015) and 5th (2016-2019). The CQI program was implemented between 2015 and 2016. The analysis included the total number of surgeries and the evolution of the most frequent procedures. Results: A total of 105,599 CCVs were performed, with an annual mean of 2,964 procedures and mortality of 5,63%. When comparing the 4th and the 5th periods, the average global volume of surgeries was increased from 2,943 to 3,139 (p = 0.368), bypass graft (CABG), from 638 to 597 (p = 0.214), heart valve surgery, from 372 to 465 (p = 0.201), and congenital heart disease surgery, from 530 to 615 (p = 0.125). The average global mortality went from 7.8% to 5% (p < 0.0001); in CABG surgery, from 5.8% to 3.1% (p < 0.0001); in heart valve surgery, from 14% to 7.5% (p < 0.0001) and in congenital heart disease surgery, from 12.1% to 9.6% (p < 0.0001). Conclusion: In spite of a recent trend towards increased surgical volume, there was a significant decrease in operative mortality in the groups studied. After the implementation of the CQI program, the mortality rates were closer to international standards.

RESUMO Objetivo: Analisar as complicações relacionadas à broncoscopia flexível (BF) e a seus procedimentos de coleta em diferentes doenças pulmonares e de vias aéreas em pacientes ambulatoriais e internados em um hospital universitário. Métodos: Foram analisadas retrospectivamente complicações precoces que ocorreram durante e após BF (em até 2 h) registrados no banco de dados do Serviço de Endoscopia Respiratória de um complexo hospitalar localizado na cidade de São Paulo (SP) entre janeiro de 2012 e dezembro de 2013. Resultados: Foram analisadas 3.473 BF. Complicações ocorreram em 185 procedimentos (5,3%): sangramento moderado a acentuado, em 2,2%; pneumotórax, em 0,7%; broncoespasmo grave, em 0,8%; complicações gerais (hipoxemia, agitação psicomotora, arritmias, vômitos e hipotensão), em 1,6%; e parada cardiorrespiratória, em 0,03%. Não houve óbitos relacionados aos procedimentos. Especificamente, nos 1.728 pacientes submetidos a biópsias, escovado brônquico e punção aspirativa por agulha fina, houve sangramentos em 75 (4,3%.) Entre os 1.191 pacientes que realizaram biópsia transbrônquica, pneumotórax (com necessidade de drenagem torácica) ocorreu em 24 (2,0%). Conclusões: Neste grupo de pacientes, a BF se mostrou um método seguro com baixo índice de complicações. A formação adequada e continuada dos médicos especialistas e da equipe de enfermagem, bem como a elaboração de protocolos de atendimento padronizados, são importantes nesse sentido.

ABSTRACT Objective: To analyze the complications related to flexible bronchoscopy (FB) and its collection procedures in outpatients and inpatients with various lung and airway diseases treated at a university hospital. Methods: This was a retrospective analysis of complications occurring during or within 2 h after FB performed between January of 2012 and December of 2013, as recorded in the database of the respiratory endoscopy department of a hospital complex in the city of São Paulo, Brazil. Results: We analyzed 3,473 FBs. Complications occurred in 185 procedures (5.3%): moderate to severe bleeding, in 2.2%; pneumothorax, in 0.7%; severe bronchospasm, in 0.8%; general complications (hypoxemia, psychomotor agitation, arrhythmias, vomiting, or hypotension), in 1.6%; and cardiopulmonary arrest, in 0.03%. There were no deaths related to the procedures. Specifically, among the 1,728 patients undergoing biopsy, bronchial brushing, or fine-needle aspiration biopsy, bleeding occurred in 75 (4.3%). Among the 1,191 patients undergoing transbronchial biopsy, severe pneumothorax (requiring chest tube drainage) occurred in 24 (2.0%). Conclusions: In our patient sample, FB proved to be a safe method with a low rate of complications. Appropriate continuing training of specialist doctors and nursing staff, as well as the development of standardized care protocols, are important for maintaining those standards.
