    OBJECTIVE: To evaluate associations between post-operative complications in patients who survive surgery and in-hospital deaths and lengths of hospital stays of patients who undergo coronary artery bypass graft surgery METHODS: Patients who underwent coronary artery bypass graft surgery and survived the operating theater were randomly selected. Information on complications and hospital lengths of stay until hospital discharge or death were retrospectively collected based on medical records and declarations of death. These aspects were estimated according to the presence of complications, frequency of complications, mortality, relative risk and attributable population risk. Mean hospital lengths of stay were compared using Wald’s statistics. RESULTS: Medical records indicating deaths in the operating theater were excluded, and 86.9% of the included records reported complications; the greatest loss of information (43.9%) was related to kidney failure. Hyperglycemia was estimated as the most frequent complication (74.6%), with an attributable risk of 31.6%. The population’s attributable risks were greater than 60% for low cardiac output (77.0%), kidney failure (64.3%) and cardiorespiratory failure (60.4%). Twelve different situations were identified for paired combinations of significant differences between average post-operative hospitalization times and complications, according to the outcome of discharge or death. CONCLUSION: Several complications were identified during the postoperative period of coronary artery bypass graft surgery, with different frequencies and impacts on mortality. Control of the myocardium at the risk of ischemia, hemodynamic stabilization and volume replacement strategies may be effective for controlling mortality rates and shortening hospital lengths of stay.

    OBJECTIVES: The objective of this study was to evaluate variables related to intra hospital mortality at 28 days, of aged persons with severe sepsis and septic shock in a clinical ICU. METHODS: One hundred and fifty-two patients aged > 65 years with severe sepsis and septic shock were followed for 28 days and the variables were collected on days 1, 3, 5, 7, 14 and 28 of stay. To compare categorical variables the Chi-square test was used and the Mann-Whitney or t test for continuous variables. All tests were double-tailed, alpha error of 0.05. RESULTS: Mean age was 82.0 ± 9.0 years and 64.5% were female. Mortality was of 47.4%. Related to death were the following: Acute Physiological and Chronic Heath Evaluation II score (p < 0.001), Sequential Organ Failure Assessment score on days 1, 3, 5, 7 (p < 0.001), length of stay in intensive care (p < 0.001), number of organ failures (p < 0.001), high serum lactate on day 3 (p = 0.05), positive troponin I (p < 0.01), echocardiographic variables (systolic diameter p = 0.005; diastolic diameter p = 0.05; shortening fraction p = 0.02), previous renal disease (p = 0.03), shock (p < 0.001), mechanical ventilation (p < 0.001) and Lawton scale (p = 0.04). CONCLUSIONS: Shock, elevated lactate, organ failure, especially respiratory were more prevalent in non-survivors. Heart dysfunction detected by echocardiographic variables and positive troponin I may play an important role in the mortality of aged patients with sepsis.
