Avaliação dos fatores de risco para morbimortalidade após cirurgia abdominal em pacientes oncológicos / Perioperative morbimortality risk factors for abdominal surgery in cancer patients

Claudia Marquez Simões 08 December 2014 (has links)
Introdução: Os pacientes oncológicos, frequentemente, apresentam complicações graves após cirurgia abdominal. No entanto, existem poucos dados sobre fatores preditores de morbimortalidade neste grupo. O objetivo deste estudo foi identificar fatores preditores de complicações graves e óbitos após cirurgia abdominal em pacientes oncológicos. Métodos: Após aprovação pela comissão de ética institucional, 308 pacientes com câncer submetidos a cirurgias abdominais foram avaliados durante 30 dias de pós-operatório quanto à mortalidade ou a complicações infecciosas, cardiovasculares, respiratórias, neurológicas, renais e cirúrgicas. Também foram avaliados o tempo de internação hospitalar e em unidade de terapia intensiva. Foi realizada análise univariada e multivariada com bootstrap para identificação dos fatores independentes preditores de risco. Resultados: De 308 pacientes operados, 106 pacientes (34,4%) desenvolveram complicações graves durante o período de acompanhamento, sendo que 7 (2,27%) evoluíram para óbito. Em um modelo de regressão logística, os fatores idade (odds ratio [OR] 1.03 IC 95% 1.01-1.06], p = 0.012), estado físico da Sociedade Americana de Anestesiologistas >= 3 (OR 2.61 [IC 95% 1.33-5.17], p = 0.003), hemoglobina pré-operatória inferior a 12 g/dL (OR 2.13 [IC 95% 1.21-4.07], p = 0.014), uso de coloides intra-operatórios (OR 1.89, [IC 95% 1.03-4.07], p = 0.047), volume total de fluidos intra-operatórios (OR 1.22 [IC 95% 0.98-1.59], p = 0.106 por litro), sangramento cirúrgico superior a 500 mL (2.07 [IC 95% 1.00-4.31], p = 0.043) e o uso de vasopressores contínuos no intra-operatório (OR 4.68 [IC 95% 1.55-27.72], p = 0.004) foram identificados como fatores de risco independentes. Conclusões: Os resultados sugerem que estratégia perioperatória baseada no tratamento da anemia pré-operatória, técnica cirúrgica hemostática, uso conservador de hemoderivados, reposição cautelosa de fluidos e prevenção do uso de coloides podem reduzir as complicações pós-operatórias em pacientes com câncer submetidos a cirurgia abdominal. Estes fatores de risco apontados podem ser úteis para futuros estudos com a aplicação de estratégias préoperatórias para otimização dos desfechos / Background: Patients undergoing abdominal surgery for solid tumours frequently develop severe postoperative complications, with impact on quality of life, costs and survival. There are only few studies describing predictive factors for complications in this group. The aim of this study was to identify factors predictive of severe complications, including mortality, in cancer patients undergoing abdominal surgery. Methods: After Institutional Review Board approval, we prospectively evaluated 308 cancer patients following abdominal surgery for 30 days in regard to major complications, including all-cause mortality and infectious, cardiovascular, respiratory, neurologic, renal and surgical complications. The need for treatment in the intensive care unit (ICU), length of the hospital and ICU stay were also evaluated. Univariate and multivariate analyses with bootstrap were performed to determine risk factors for major complications including 30-day mortality. Results: One hundred and six patients (34.4%) developed a severe complication and 7 (2,27%) died during the 30-day follow-up period. Logistic regression identified age (odds ratio [OR] 1.03 [95% CI 1.01-1.06], p=0.012), ASA physical status greater than or equal to 3 (OR 2.61 [95% CI 1.33-5.17], p=0.003), a preoperative hemoglobin level lower than 12 g/dL (OR 2.13 [95% CI 1.21-4.07], p=0.014), intraoperative use of colloids (OR 1.89, [95% CI 1.03-4.07], p=0.047), increased amounts of intravenous fluids (OR 1.22 [95% CI 0.98-1.59], p=0.106 per litre), intraoperative blood losses greater than 500 mL (2.07 [95% CI 1.00-4.31], p=0.043), and the use of continuous vasopressors (OR 4.68 [95% CI 1.55-27.72], p=0.004) as independent risk predictors. Conclusions: Our findings suggest that a perioperative strategy based on the treatment of preoperative anemia, implementation of haemostatic surgical techniques, conservative blood management, inflammation control and the avoidance of colloids may reduce postoperative complications in cancer patients after abdominal surgery. These markers may be useful for further studies to develop perioperative optimization strategies for this population
