    Introduction: The phase angle has been listed as a nutritional marker and its useful role in critically ill patients, but its role as a patient-to-patient tool has not yet been tested. This study sought to evaluate the phase angle as a proposal to determine nutritional risk in critically ill patients hospitalized in cardiac intensive care units. Methods: Transversal study, coupled to a prospective analysis variable (hospitalization outcome) and involving adult and elderly male and female patients in cardiac intensive care units. The nutritional risk was determined by using the NUTRICscore, the phase angle was obtained through bioelectrical impedance analysis and other data, through the clinical record. A significance level of p <0.05 was used for all statistical analysis. Results: 79 patients were included and resulted in homogeneous distribution among the sexes and an average age of 67.2 ± 13.7 years. Most of the sample had malnutrition according to the body mass index (BMI) (46.7%; CI: 36.0-57.8) and due to the adequacy of the arm circumference (40.8%; CI: 34.0-52.0). According to the NUTRIC score, 59.5% (CI: 48.5-69.3) had a high nutritional risk, and 68.4% (CI: 57.4-77.6) had a low phase angle (≤5.5 °). Correlation between the phase angle and age (p = 0.010) and BMI (p = 0.023) was verified. A good sensitivity (72%; CI: 55.6-81.9) and specificity (68%; CI: 42.5-77.5) of the low phase angle were obtained to detect nutritional risk by NUTRIC. Conclusions: The PhA had good results of sensitivity and specificity but should be used with caution to determine the nutritional risk in critically ill cardiac patients.Introducción: El ángulo de fase se ha catalogado como un marcador nutricional y su papel útil en pacientes críticos, pero aún no se ha probado su papel como herramienta de paciente a paciente. Este estudio buscó evaluar el ángulo de fase como propuesta para determinar el riesgo nutricional en pacientes críticos hospitalizados en unidades de cuidados intensivos cardíacos. Metodología: Estudio transversal, acoplado a una variable de análisis prospectivo (resultado de hospitalización);participaron pacientes adultos y adultos mayores del sexo masculino y femenino en unidades de cuidados intensivos cardíacos. El riesgo nutricional se determinó mediante el NUTRICscore, el ángulo de fase se obtuvo a través del análisis de impedancia bioeléctrica y otros datos, a través de la historia clínica. Se utilizó un nivel de significación de p <0,05 para todos los análisis estadísticos. Resultados: Se incluyeron 79 pacientes y resultó una distribución homogénea entre los sexos y una edad promedio de 67,2±13,7 años. La mayor parte de la muestra presentaba desnutrición según índice de masa corporal (IMC) (46.7%; CI: 36.0-57.8) y por adecuación del perímetro braquial (40,8%; CI: 34.0-52.0). De acuerdo con el puntaje NUTRIC, el 59,5% (CI: 48.5-69.3) tenía un riesgo nutricional alto y el 68,4% (CI: 57.4-77.6) tenía un ángulo de fase bajo (≤ 5,5°). Se verificó correlación entre el ángulo de fase y la edad (p = 0,010) y el IMC (p = 0,023). Se obtuvo una buena sensibilidad (72%; CI: 55.6-81.9) y especificidad (68%; CI: 42.5-77.5) del ángulo de fase bajo para detectar riesgo nutricional por NUTRIC. Conclusiones: El PhA tuvo buenos resultados de sensibilidad y especificidad, pero debe ser utilizado con precaución para determinar el riesgo nutricional en pacientes cardíacos críticos

    Objective: Analyze the publications focusing on the administration of drugs in nursing care which were made available in the databases within the period from 2007 to 2011. Method: This is an integrative review study carried out in databases of the Virtual Health Library (LILACS and SciELO), in May and June 2011. Results: In the discussions stood out: training with the aid of the virtual learning environment through distance education, errors in prescriptions which led to errors in drug administration, and importance of prevention to avoid mistakes. Conclusion: If the prescriptions are prepared having guidelines, recommendations, and team training as a basis, besides communication between the professionals, one may say that the risks related to errors in drug administration tend to sharply decrease
