OBJECTIVE: Anemia is common in severely ill patients, and blood sampling plays a relevant causative role. Consequently, blood transfusions are frequent an related to several complications. Trying to reduce the transfusion-related risk, minimizing blood loss is mandatory. Thus, this work aimed to evaluate a closed blood sampling system as a strategy to spare unnecessary blood losses and transfusions. METHODS: This was a prospective, randomized, controlled, multicenter, 6 months, clinical trial. The patients were assigned to either VAMP (Venous Arterial Blood Management Protection) group, using a closed blood sampling system, or control group. The groups' transfusion rate, as well as hemoglobin (Hb) and Hematocrit (Ht) changes were compared for 14 days. RESULTS: Were included 127 patients, 65 assigned to the control group, and 62 to VAMP. During the intensive care unit stay, both groups experienced both hemoglobin and hematocrit drops. However, when the final Ht and Hb were compared between the groups, a difference was identified with higher values in the VAMP group (p=0.03; p=0.006, respectively). No statistical difference was found for both groups transfusion rates, although the VAMP group had an absolute 12% blood transfusion reduction. CONCLUSION: The use of a closed blood sampling system was able to minimize blood count values changes, however failed to reduce transfusions rate.

Currently, aging of the population is a widespread global phenomenon. Therefore, the assessment of prognosis in elderly patients is needed. This study aims to identify risk factors in a population of elderly patients admitted in the intensive care unit METHODS: A prospective study in the intensive care unit of a general tertiary hospital was carried out for five months. Patients with 65 years or more of age, who stayed in the intensive care unit for 24 hours or more were included and those at the-end-of-life, patients readmitted to intensive care unit during the same hospital stay were excluded. RESULTS: In this study 199 patients were involved, with a mean age of 75.4±6.8 years, and 58.8% were female. Mortality was 57.3%. The mean APACHE II, SOFA, MODS and Katz index (assessment of daily activities) were respectively 20.0±5.8, 6.8±3.9, 2.4±1.9 and 5.3±1.6. Most patients were postoperative 59.3% and 41.6% were under invasive mechanical ventilation. At regression analysis, the independent determinants of higher mortality were: older age (76.9±6.7 years death versus 73.3±6.5 years discharge, P<0.001, OR=1.08, CI 95% 1.01-1. 16), the Katz index (4.9±1.9 deaths versus 5.7±0.9 discharge, p=0.001, OR=0.66, CI 95% 0.45-0.98), hyperglycemia (158.1±69.0 death versus 139.6±48.5 discharge p=0.041; OR=1.02; CI 95% 1.01-1.03) and need for mechanical ventilation at admission to the intensive care unit (57.0% death versus 20.5% discharge p <0.001, OR=3.57, CI 95% 1.24-10.3). CONCLUSION: Elderly patients admitted to the intensive care unit that have difficulties in performing daily activities, hyperglycemia and who are under invasive mechanical ventilation had a worse hospital prognosis.
