RESUMEN
Abstract Objective To analyze the effects of an ERAS program on complication rates, readmission, and length of stay in patients undergoing pulmonary resection in a tertiary university hospital. Methods Ambispective cohort study with a prospective arm of 50 patients undergoing thoracic surgery within an ERAS program (ERAS group) versus a retrospective arm of 50 patients undergoing surgery before the protocol was implemented (Standard group). The primary outcome was the number of patients with 30-day surgical complications. Secondary outcomes included ERAS adherence, non-surgical complications, mortality, readmission, reintervention rate, pain, and hospital length of stay. We performed a multivariate logistic analysis to study the correlation between outcomes and ERAS adherence. Results In the univariate analysis, we found no difference between the two groups in terms of surgical complications (Standard 18 [36%] vs. ERAS 12 [24%], p = 0.19). In the ERAS group, only the readmission rate was significantly lower (Standard 15 [30%] vs. ERAS 6 [12%], p = 0.03). In the multivariate analysis, ERAS adherence was the only factor associated with a reduction in surgical complications (OR [95% CI] = 0.02 [0.00, 0.59], p = 0.03) and length of stay (HR [95% CI] = 18.5 [4.39, 78.4], p < 0.001). Conclusions The ERAS program significantly reduced the readmission rate at our hospital. Adherence to the ERAS protocol reduced surgical complications and length of stay.

One of the most used painkillers is acetaminophen (APAP), which is safe at the right dose. However, several studies have described populations susceptible to APAP-induced liver damage, mainly in livers with steatosis. Thus, clinicians should consider the presence of obesity and other chronic liver diseases like nonalcoholic fatty liver disease (NAFLD) when indicating treatment with APAP. Liver damage from this drug is generated through its metabolite N-acetyl-p-benzoquinone imine, which is detoxified with glutathione (GSH). Prior depletion of GSH in steatotic hepatocytes plays a key role in APAP-induced hepatotoxicity in people with obesity and NAFLD. The knowledge about the damage to the liver or APAP in susceptible people like the obese and those with NAFLD is of great relevance for the sanitary sector because it would imply strategies of different therapeutic approach in such patients. This paper reviews the role of APAP in liver damage in the presence of obesity, NAFLD, and nonalcoholic steatohepatitis.

Abstract Background Enhanced recovery after surgery (ERAS) protocols consist of a set of perioperative measures aimed at improving patient recovery and decreasing length of stay and postoperative complications. We assess the implementation and outcomes of an ERAS program for colorectal surgery. Methods Single center observational study. Data were collected from consecutive patients undergoing open or laparoscopic colorectal surgery during 2 time periods, 3 years before (Pre-ERAS) and 2 years after (Post-ERAS) the implementation of an ERAS protocol. Baseline characteristics of both groups were compared. The primary outcome was the number of patients with 180 days follow-up with moderate or severe complications; secondary outcomes were postoperative length of stay, and specific complications. Data were extracted from patient records. Results There were 360 patients in the Pre-ERAS group and 319 patients in the Post-ERAS Group. 214 (59.8%) patients developed at least one complication in the pre ERAS group, versus 163 patients in the Post-ERAS group (51.10%). More patients in the Pre-ERAS group developed moderate or severe complications (31.9% vs. 22.26%, p = 0.009); and severe complications (15.5% vs. 5.3%; p < 0.0001). The median length of stay was 13 (17) days in Pre-ERAS Group and 11 (10) days in the Post-ERAS Group (p = 0.034). No differences were found on mortality rates (4.7% vs. 2.5%; p = 0.154), or readmission (6.39% vs. 4.39%; p = 0.31). Overall ERAS protocol compliance in the Post-ERAS cohort was 88%. Conclusions The implementation of ERAS protocol for colorectal surgery was associated with a significantly reduction of postoperative complications and length of stay.
Resumo Justificativa O protocolo ERAS - do Inglês Enhanced Recovery After Surgery - consiste em um conjunto de medidas perioperatórias destinadas a melhorar a recuperação do paciente e diminuir o tempo de internação e as complicações pós-operatórias. Avaliamos a implantação e os resultados de um protocolo ERAS para cirurgia colorretal. Métodos Estudo observacional em centro único. Os dados foram coletados de pacientes consecutivos submetidos à cirurgia colorretal aberta ou laparoscópica durante dois períodos: três anos antes (pré-ERAS) e dois anos após (pós-ERAS) a implantação de um protocolo ERAS. As características basais de ambos os grupos foram comparadas. O desfecho primário foi o número de pacientes com 180 dias de acompanhamento com complicações moderadas ou graves. Os desfechos secundários foram tempo de internação pós-cirurgia e complicações específicas. Os dados foram extraídos de prontuários dos pacientes. Resultados O grupo pré-ERAS foi composto por 360 pacientes e o grupo pós-ERAS por 319. No grupo pré ERAS, 214 pacientes (59,8%) desenvolveram pelo menos uma complicação versus 163 (51,10%) no grupo pós-ERAS. Um número maior de pacientes do grupo pré-ERAS desenvolveu complicações moderadas ou graves (31,9% vs. 22,26%, p = 0,009); e complicações graves (15,5% vs. 5,3%; p < 0,0001). A mediana do tempo de internação foi de 13 (17) dias no grupo pré-ERAS e de 11 (10) dias no grupo pós-ERAS (p = 0,034). Não houve diferença nas taxas de mortalidade (4,7% vs. 2,5%; p = 0,1554) ou de reinternação (6,39% vs. 4,39%; p = 0,31). A conformidade geral do protocolo ERAS na coorte pós-ERAS foi de 88%. Conclusões A implantação do protocolo ERAS para cirurgia colorretal foi associada a uma redução significativa das complicações pós-operatórias e do tempo de internação.

RESUMEN
Abstract Background: The goal directed hemodynamic therapy is an approach focused on the use of cardiac output and related parameters as end-points for fluids and drugs to optimize tissue perfusion and oxygen delivery. Primary aim: To determine the effects of intraoperative goal directed hemodynamic therapy on postoperative complications rates. Methods: A meta-analysis was carried out of the effects of goal directed hemodynamic therapy in adult noncardiac surgery on postoperative complications and mortality using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. A systematic search was performed in Medline PubMed, Embase, and the Cochrane Library (last update, October 2014). Inclusion criteria were randomized clinical trials in which intraoperative goal directed hemodynamic therapy was compared to conventional fluid management in noncardiac surgery. Exclusion criteria were trauma and pediatric surgery studies and that using pulmonary artery catheter. End-points were postoperative complications (primary) and mortality (secondary). Those studies that fulfilled the entry criteria were examined in full and subjected to quantifiable analysis, predefined subgroup analysis (stratified by type of monitor, therapy, and hemodynamic goal), and predefined sensitivity analysis. Results: 51 RCTs were initially identified, 24 fulfilling the inclusion criteria. 5 randomized clinical trials were added by manual search, resulting in 29 randomized clinical trials in the final analysis, including 2654 patients. A significant reduction in complications for goal directed hemodynamic therapy was observed (RR: 0.70, 95% CI: 0.62-0.79, p < 0.001). No significant decrease in mortality was achieved (RR: 0.76, 95% CI: 0.45-1.28, p = 0.30). Quality sensitive analyses confirmed the main overall results. Conclusions: Intraoperative goal directed hemodynamic therapy with minimally invasive monitoring decreases postoperative complications in noncardiac surgery, although it was not able to show a significant decrease in mortality rate.
Resumo Justificativa: A terapia hemodinâmica alvo-dirigida (THAD) é uma abordagem focada no uso do débito cardíaco (DC) e parâmetros relacionados, como desfechos para fluidos e medicamentos para aprimorar a perfusão tecidual e o fornecimento de oxigênio. Objetivo primário: determinar os efeitos da THAD sobre as taxas de complicações no pós-operatório. Métodos: Metanálise dos efeitos da THAD em cirurgias não cardíacas de adultos sobre as complicações pós-operatórias e mortalidade, com a metodologia PRISMA. Uma busca sistemática foi feita no Medline PubMed, Embase e Biblioteca Cochrane (última atualização, outubro de 2014). Os critérios de inclusão foram estudos clínicos randômicos (ECRs) nos quais a THAD no intraoperatório foi comparada com a terapia convencional de reposição de líquidos em cirurgia não cardíaca. Os critérios de exclusão foram traumatismo e estudos de cirurgia pediátrica e aqueles que usaram cateter de artéria pulmonar. Os desfechos, primário e secundário, foram complicações pós-operatórias e mortalidade, respectivamente. Os estudos que atenderam aos critérios de inclusão foram examinados na íntegra e submetidos à análise quantitativa, análise de subgrupo pré-definido (estratificada por tipo de monitor, terapia e objetivo hemodinâmico) e análise de sensibilidade pré-definida. Resultados: 51 ECRs foram identificados inicialmente, 24 atenderam aos critérios de inclusão. Cinco ECRs foram adicionados por busca manual, resultando em 29 ECRs para análise final, incluindo 2.654 pacientes. Uma redução significativa das complicações para a THAD (RR: 0,70, IC de 95%: 0,62-0,79, p < 0,001). Nenhuma diminuição significativa na mortalidade foi observada (RR: 0,76, IC de 95%: 0,45-1,28, p = 0,30). Análises de sensibilidade qualitativa confirmaram os principais resultados gerais. Conclusões: THAD no intraoperatório com monitoração minimamente invasiva diminui as complicações no pós-operatório de cirurgia não cardíaca, embora não tenha mostrado uma redução significativa da taxa de mortalidade.
