RESUMEN
Since allogeneic blood transfusion (ABT) is not harmless, multiple alternatives to ABT (AABT) have emerged, though there is great variability in their indications and appropriate use. This variability results from the interaction of a number of factors, including the specialty of the physician, knowledge and preferences, the degree of anemia, transfusion policy, and AABT availability. Since AABTs are not harmless and may not meet cost-effectiveness criteria, such variability is unacceptable. The Spanish Societies of Anesthesiology (SEDAR), Hematology and Hemotherapy (SEHH), Hospital Pharmacy (SEFH), Critical Care Medicine (SEMICYUC), Thrombosis and Hemostasis (SETH) and Blood Transfusion (SETS) have developed a Consensus Document for the proper use of AABTs. A panel of experts convened by these 6 Societies have conducted a systematic review of the medical literature and have developed the 2013 Seville Consensus Document on Alternatives to Allogeneic Blood Transfusion, which only considers those AABT aimed at decreasing the transfusion of packed red cells. AABTs are defined as any pharmacological or non-pharmacological measure aimed at decreasing the transfusion of red blood cell concentrates, while preserving patient safety. For each AABT, the main question formulated, positively or negatively, is: « Does this particular AABT reduce the transfusion rate or not?¼ All the recommendations on the use of AABTs were formulated according to the Grades of Recommendation Assessment, Development and Evaluation (GRADE) methodology.

La anemia es muy frecuente en los pacientes médicos y quirúrgicos ingresados en la Unidad de Cuidados Intensivos (UCI), siendo generalmente de origen multifactorial. Para evitar los efectos deletéreos de la anemia, un 40% de estos pacientes suele ser transfundido, elevándose esta cifra al 70% si la estancia en UCI supera los 7 días. Sin embargo, la transfusión de sangre alogénica se asocia con un aumento dosis-dependiente de la morbilidad y mortalidad. Por el contrario, la administración de eritropoyetina recombinante junto con suplementos de hierro, especialmente hierro endovenoso, estimula la eritropoyesis y disminuye la necesidad de transfusión, aunque no desciende la mortalidad. Es necesario por tanto realizar más estudios, con poder estadístico suficiente y período de seguimiento adecuado, para conocer si el tratamiento de la anemia del paciente crítico con eritropoyetina y con hierro endovenoso mejora el pronóstico de estos pacientes, así como para optimizar las pautas y dosis de dichos tratamientos
Anemia is a common condition among medical and surgical patients admitted to the intensive care unit (ICU) and generally has a multifactorial origin. In order to avoid the deleterious effects of anemia, 40% of ICU patients receive allogenic blood transfusion (ABT). This figure increases up to 70% if the ICU stay is longer than 7 days. However, ABT is associated with a dose-dependent increase in morbidity and mortality. In contrast, the administration of exogenous erythropoietin plus iron supplements, especially iv iron, improves anemia and reduces ABT requirements, although it does not reduce mortality. To ascertain whether treatment of anemia in the critically ill with exogenous erythropoietin and iron might improve outcomes and to optimize drug administration schedules and dosage, further studies with sufficient statistical power and adequate follow-up are warranted

BACKGROUND: A prospective multicentre study was undertaken to compare the efficacy of intravenous ciprofloxacin or imipenem in the treatment of severe nosocomial pneumonia requiring mechanical ventilation. METHODS: Patients with a clinical suspicion of pneumonia were randomised to receive either ciprofloxacin (800-1200 mg/day) or imipenem (2-4 g/day) in doses adjusted for renal function and specimens of the lower respiratory tract were taken. Patients were included in the study when specimens showed significant growth for potentially pathogenic microorganisms in quantitative bacterial cultures (n = 75, ciprofloxacin 41/75 (55%); imipenem 34/75 (45%)). The clinical and bacteriological success rates were the primary and secondary efficacy variables. An intent-to-treat analysis was performed for all randomised patients who received at least one dose of the study medication (n = 149, ciprofloxacin 72/149 (48%), imipenem 77/149 (52%)). RESULTS: The success rates were generally good, but neither the clinical success rates (ciprofloxacin, 29/41 (71%), imipenem, 27/34 (79%); 95% CI -10.8 to 28.1; p = 0.435) nor the bacteriological response rate (ciprofloxacin, 20/41 (49%), imipenem, 17/34 (50%); 95% CI -21.5 to 23.9; p = 1.0) were significantly different between the study arms. Pseudomonas aeruginosa was recovered in 26/75 patients (35%) and clinical (ciprofloxacin, 10/14 (71%), imipenem, 8/12 (67%); 95% CI -40.4 to 30.9; p = 1.0) and bacteriological response rates (ciprofloxacin, 7/14 (50%), imipenem, 3/12 (25%), 95% CI -60.9 to 10.9, p = 0.247) were not significantly different in this subgroup of patients. Resistance of Pseudomonas aeruginosa developed in 5/26 cases (19%), 1/14 (7%) to ciprofloxacin and 4/12 (33%) to imipenem (p = 0.147), and the mortality was 12/75 (16%) with no difference between treatment groups (ciprofloxacin, 8/41(24%), imipenem 4/34 (17%); p = 0.362). The clinical response was evaluable in 109/149 patients (73%) in the intent-to-treat analysis and was successful in 74/109 patients (68%). The clinical response rates were also not significantly different in the intent-to-treat analysis (ciprofloxacin, 34/52 (65%), imipenem, 40/57 (70%); 95% CI -12.8 to 22.3; p = 0.746). CONCLUSIONS: Treatment with either ciprofloxacin or imipenem was effective in a selected group of patients with microbiologically confirmed, severe nosocomial pneumonia requiring mechanical ventilation. Although no differences between the study medication could be documented in this trial, smaller differences between treatment arms may have been missed because of sample size limitations.
