Goal-directed therapy guided by the FloTrac sensor in major surgery: a systematic review and meta-analysis.

OBJECTIVE: To provide insights into the potential benefits of goal-directed therapy guided by FloTrac in reducing postoperative complications and improving outcomes. METHODS: We performed a systematic review and meta-analysis of randomized controlled trials to evaluate goal-directed therapy guided by FloTrac in major surgery, comparing goal-directed therapy with usual care or invasive monitoring in cardiac and noncardiac surgery subgroups. The quality of the articles and evidence were evaluated with a risk of bias tool and GRADE. RESULTS: We included 29 randomized controlled trials with 3,468 patients. Goal-directed therapy significantly reduced the duration of hospital stay (mean difference -1.43 days; 95%CI 2.07 to -0.79; I2 81%), intensive care unit stay (mean difference -0.77 days; 95%CI -1.18 to -0.36; I2 93%), and mechanical ventilation (mean difference -2.48 hours, 95%CI -4.10 to -0.86, I2 63%). There was no statistically significant difference in mortality, myocardial infarction, acute kidney injury or hypotension, but goal-directed therapy significantly reduced the risk of heart failure or pulmonary edema (RR 0.46; 95%CI 0.23 - 0.92; I2 0%). CONCLUSION: Goal-directed therapy guided by the FloTrac sensor improved clinical outcomes and shortened the length of stay in the hospital and intensive care unit in patients undergoing major surgery. Further research can validate these results using specific protocols and better understand the potential benefits of FloTrac beyond these outcomes.

RESUMO Objetivo Fornecer informações sobre os possíveis benefícios da terapia guiada por metas utilizando o sensor FloTrac na redução de complicações pós-operatórias e na melhoria dos desfechos. Métodos Realizamos uma revisão sistemática e uma metanálise de estudos controlados e randomizados para avaliar a terapia guiada por metas utilizando o sensor FloTrac em cirurgias de grande porte, comparando a terapia guiada por metas com os cuidados habituais ou o monitoramento invasivo em subgrupos de cirurgias cardíacas e não cardíacas. A qualidade dos artigos e das evidências foi avaliada com uma ferramenta de risco de viés e o GRADE. Resultados Incluímos 29 estudos controlados e randomizados com 3.468 pacientes. A terapia guiada por metas reduziu significativamente a duração da internação hospitalar (diferença média de -1,43 dia; IC95% 2,07 - -0,79; I2 81%), a internação na unidade de terapia intensiva (diferença média de -0,77 dia; IC95% -1,18 - -0,36; I2 93%) e a ventilação mecânica (diferença média de -2,48 horas, IC95% -4,10 - -0,86; I2 63%). Não houve diferença estatisticamente significativa na mortalidade, no infarto do miocárdio, na lesão renal aguda e nem na hipotensão, mas a terapia guiada por metas reduziu significativamente o risco de insuficiência cardíaca ou edema pulmonar (risco relativo de 0,46; IC95% 0,23 - 0,92; I2 0%). Conclusão A terapia guiada por metas utilizando o sensor FloTrac melhorou os desfechos clínicos e reduziu o tempo de internação no hospital e na unidade de terapia intensiva em pacientes submetidos a cirurgias de grande porte. Outras pesquisas podem validar esses resultados usando protocolos específicos e entender melhor os possíveis benefícios do FloTrac além desses desfechos.

Performance of High Mobility Protein Group 1 and Interleukin-6 as Predictors of Outcomes Resulting from Variceal Bleeding in Patients with Advanced Chronic Liver Disease.

Variceal bleeding is a serious complication in cirrhotic patients and is related to increased expression of inflammatory mediators that accentuate circulatory dysfunction. The study aims to evaluate the performance of high mobility protein group 1 (HMG1) and interleukin-6 (IL-6) as predictors of acute kidney injury (AKI), infection and death in these patients. Fifty patients who were diagnosed with advanced chronic liver disease with variceal bleeding were included. The mean age was 52.8 ± 10.8 years, and 33 (66%) were male. Twenty-one (42%) patients were classified as Child-Pugh C, 21 (42%) Child-Pugh B and 8 (16%) Child-Pugh A. The mean HMG1 serum level was 2872.36 pg/mL ± 2491.94, and the median IL-6 serum level was 47.26 pg/mL (0-1102.4). In AKI, the serum level of HMG1 that performed best on the ROC curve was 3317.9 pg/mL. The IL-6 serum level was not associated with AKI. HMG1 and IL-6 cut-off values that better predicted infection were 3317.9 pg/mL and 72.9 pg/mL, and for mortality, the values were 2668 pg/mL and 84.5 pg/mL, respectively. In multivariate analysis, the variables that were associated with AKI and infection outcomes were model for end-stage liver disease and HMG1. Infections were related to the risk of death. Clinical and laboratory variables related to the outcomes were identified. Serum levels of HMG1 were associated with AKI and infection and had good performance in the ROC curve. IL-6 levels were not maintained in logistic regression outcomes but had good performance in infection and death outcomes. Such data will be useful for comparisons and possible future validations.

Clinical Characteristics and In-Hospital Mortality of Cardiac Arrest Survivors in Brazil: A Large Retrospective Multicenter Cohort Study.

OBJECTIVES: Data on cardiac arrest survivors from developing countries are scarce. This study investigated clinical characteristics associated with in-hospital mortality in resuscitated patients following cardiac arrest in Brazil. DESIGN: Retrospective analysis of prospectively collected data. SETTING: Ninety-two general ICUs from 55 hospitals in Brazil between 2014 and 2015. PATIENTS: Adult patients with cardiac arrest admitted to the ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We analyzed 2,296 patients (53% men; median 67 yr (interquartile range, 54-79 yr]). Eight-hundred patients (35%) had a primary admission diagnosis of cardiac arrest suggesting an out-of-hospital cardiac arrest; the remainder occurred after admission, comprising an in-hospital cardiac arrest cohort. Overall, in-hospital mortality was 83%, with only 6% undergoing withholding/withdrawal-of-life support. Random-effects multivariable Cox regression was used to assess associations with survival. After adjusting for age, sex, and severity scores, mortality was associated with shock (adjusted odds ratio, 1.25 [95% CI, 1.11-1.39]; p < 0.001), temperature dysregulation (adjusted odds ratio for normothermia, 0.85 [95% CI, 0.76-0.95]; p = 0.007), increased lactate levels above 4 mmol/L (adjusted odds ratio, 1.33 [95% CI, 1.1-1.6; p = 0.009), and surgical or cardiac cases (adjusted odds ratio, 0.72 [95% CI, 0.6-0.86]; p = 0.002). In addition, survival was better in patients with probable out-of-hospital cardiac arrest, unless ICU admission was delayed (adjusted odds ratio for interaction, 1.63 [95% CI, 1.21-2.21]; p = 004). CONCLUSIONS: In a large multicenter cardiac arrest cohort from Brazil, we found a high mortality rate and infrequent withholding/withdrawal of life support. We also identified patient profiles associated with worse survival, such as those with shock/hypoperfusion and arrest secondary to nonsurgical admission diagnoses. Our findings unveil opportunities to improve postarrest care in developing countries, such as prompt ICU admission, expansion of the use of targeted temperature management, and implementation of shock reversal strategies (i.e., early coronary angiography), according to modern guidelines recommendations.

Avaliação do comportamento dos níveis séricos de HMGB1 e IL-6 como preditores de infecção, injúria renal aguda e mortalidade em pacientes cirróticos com varizes sangrantes / Evaluation of the behavior of levels of hmgb1 and il6 as predictors of infection, acute kidney injury and mortality in cirrhotic patients with variceal bleeding

ABSTRACT BACKGROUND: Gastroesophageal varices and associated bleeding are a major cause of morbidity and mortality in cirrhotic patients. OBJECTIVE: To evaluate the potential role of the biomarkers HMGB1 (High Mobility Group Box 1) and IL-6 (Interleukin-6) as predictors of infection, acute kidney injury and mortality in these patients. METHODS: It is a prospective, observational study that included 32 cirrhotic patients with variceal bleeding. RESULTS: The subjects'mean age was 52±5 years and 20 (62.5%) were male. The average MELD was 17.53±5 and the average MELD-Na was 20.63±6.06. Thirty patients (93.3%) patients were Child-Pugh class B or C. Infection was present in 9 subjects (28.1%), acute kidney injury was present in 6 (18.1%) and 4 (12.5%) patients died. The median serum levels of HMGB1 were 1487 pg/mL (0.1 to 8593.1) and the median serum level of IL-6 was 62.1 pg/mL (0.1 to 1102.4). The serum levels of HMGB1 and IL-6 were significantly higher in patients who developed infection, acute kidney injury and death (P<0.05). The Spearman's correlations for HMGB1 and IL-6 were 0.794 and 0.374 for infection, 0.53 and 0.374 for acute kidney injury and 0.467 and 0.404 for death, respectively. CONCLUSION: Serum levels of HMGB1 and IL-6 were higher in patients with the three studied outcomes. HMGB1 serum levels showed a high correlation with infection and a moderate correlation with acute kidney injury and death, while IL-6 showed a moderate correlation with infection and death and a low correlation with acute kidney injury.

RESUMO CONTEXTO: Varizes esofagogástricas são a maior causa de morbimortalidade em pacientes cirróticos. OBJETIVO: Avaliar o papel de biomarcadores, High Mobility Group Box 1 (HMGB 1) e interleucina-6 (IL-6) como preditores de infecção, injúria renal aguda e mortalidade nestes pacientes. MÉTODOS: Estudo prospectivo, observacional que incluiu 32 pacientes com cirrose hepática na fase aguda do sangramento. RESULTADOS: A média de idade dos pacientes foi de 52±5 anos sendo 20 (62,5%) do gênero masculino. A média do MELD foi de 17,53±5 e a média do MELD-Na 20,63±6,06. Trinta (93,3%) pacientes foram classificados como Child B ou C. Complicação infecciosa esteve presente em 9 (28,1%) pacientes, injúria renal aguda em 6 (18,1%) e 4 (12,5%) evoluíram para o óbito. A mediana do nível sérico de HMGB 1 foi de 1487 pg/mL (0,1- 8593,1) e da IL-6 foi de 62,1pg/mL (0,1-1102,4). Os níveis séricos de HMGB 1 e IL-6 foram significativamente maiores nos pacientes que evoluíram com infecção, injúria renal aguda e óbito (P<0,05). Os valores da correlação de Spearman para os níveis séricos de HMGB 1 e IL-6 foram de 0,794 e 0,374 para infecção, 0,53 e 0,374 para injuria renal aguda e 0,467 e 0,404 para óbito, respectivamente. CONCLUSÃO: Níveis séricos de HMGB 1 e IL-6 foram maiores nos três desfechos estudados. Níveis séricos de HMGB 1 apresentaram alta correlação para com o desfecho infecção e moderada correlação para com injúria renal aguda e óbito, enquanto os níveis séricos de IL-6 apresentaram moderada correlação para com infecção e óbito e baixa correlação para com injúria renal aguda.
