RESUMENEstudio descriptivo, transversal y retrospectivo de abordaje cuantitativo, cuyo objetivo fue relacionar el Índice de Masa Corporal (IMC) a los eventos ocurridos en el postoperatorio de la cirugía de revascularización miocárdica. La recolección de datos se realizó entre abril y junio del 2012. Los participantes fueron divididos según su IMC en tres grupos: aquellos con estado nutricional normal, con sobrepeso y obesos. El análisis de datos se basó en la estadística descriptiva. Se encontró que los participantes eutróficos tuvieron más complicaciones, especialmente pulmonares. Ente los individuos con sobrepeso y obesidad destacaron las complicaciones cardiovasculares, teniendo los sujetos con obesidad peor pronóstico. Se concluyó que no existe asociación estadísticamente significativa entre la obesidad y el sobrepeso con la mayor frecuencia de complicaciones postoperatorias a pesar de la ocurrencia de complicaciones cardiovasculares en esos grupos. El conocimiento de esas posibles complicaciones posibilita la planificación adecuada de los cuidados de enfermería a partir de la práctica basada en la evidencia. DESCRIPTORES ABSTRACTThis is a descriptive, retrospective study with cross-sectional quantitative approach, which aimed to relate the body mass index with events in the postoperative period of the myocardial revascularization surgery with use of extracorporeal circulation. The data collection period was between April and June/2012. Patients were divided according to the body mass index and classified as without excess of weight, overweight or obese. The data analysis was based on the descriptive statistics. The patients without excess of weight had more complications, especially those related to the lungs. Among overweight and obese individuals, the cardiovascular complications stood out. The obese subjects had the worse prognostic. Obesity and overweight did not have statistically significant association with a higher frequency of postoperative complications, in spite of the occurrence of cardiovascular complications in this group. The patients without excess of weight had higher risks of developing neurological events.

This study aimed to verify the presence of chest pain in a reference emergency cardiac unit of Recife, PE, Brazil. This is a cross-sectional, descriptive-exploratory study, with a quantitative approach. Between December 2012 and February 2013, data from 39 patients admitted to the unit with chest pain were collected. For comparison between the averages, the Mann-Whitney test was used and the Pearson correlation was used to verify the association between numerical variables and pain scores and time between symptoms' onset and attendance (delta t). The main presentations were retrosternal chest pain isolated (51.3%) and combined with radiation (33.3%). The average scores reported for pain was 5.15±1.63 and the delta t of the sample was 14.95±8:48h. The delay to arrive at the reference unit harms the diagnosis and the possibility of initiating reperfusion therapy in pre-hospital care should be considered.

Objetivou-se verificar a apresentação da dor torácica em uma unidade de referência em emergência cardiológica do Recife, PE, Brasil. Trata-se de um estudo de corte transversal, descritivo-exploratório, de abordagem quantitativa. Foram coletados entre dezembro de 2012 e fevereiro de 2013, dados de 39 pacientes admitidos na unidade com dor torácica. Para a comparação entre as médias foi utilizado o teste de Mann-Whitney e a correlação de Pearson foi utilizada para verificar a associação entre variáveis numéricas com os escores de dor e tempo entre início dos sintomas e atendimento (delta t). As principais apresentações foram a dor retroesternal isolada (51,3%) e combinada à irradiações (33,3%). O escore médio referido para dor foi de 5,15±1,63 e o delta t da amostra foi de 14,95±8,48h. A demora até a unidade de referência prejudica o diagnóstico e deve-se considerar a hipótese de a terapia de reperfusão iniciar no atendimento pré-hospitalar.

Estudio de corte transversal, descriptivo, exploratorio, cuantitativo. Fueron recogidos entre diciembre de 2012 y febrero de 2013 los datos de 39 pacientes ingresados en la unidad de dolor torácico. Para comparación entre las medias, fue utilizado test de Mann-Whitney y correlación de Pearson para verificar asociación entre variables numéricas con puntuaciones de dolor y tiempo entre el inicio de los síntomas y atendimiento (delta t). Las principales presentaciones fueron dolor retro esternal solo (51,3%) y combinada con la irradiación (33,3%). La puntuación promedia para dolor retro esternal solo fue de 5,15 ± 1,63 y el delta T de la muestra fue de 14,95 ± 8,48 h. El retraso de la unidad de referencia perjudica el diagnóstico y debe considerarse la posibilidad de iniciar la terapia de reperfusión en la atención prehospitalaria.

Objective: To analyze the retention of knowledge and skills of nursing professionals following training and retraining on cardiopulmonary resuscitation. Method: This is an intervention, prospective, and analytical study in which 56 nursing professionals received theoretical and practical training in in-service cardiopulmonary resuscitation. Nine months after the first training (T1), these professionals participated in a retraining (T2). They were followed up for 18 months. The linear trend of knowledge and skills in the period following training was calculated and the Wilcoxon test was applied. Results: Interventions increased the knowledge and skills of professionals significantly; however, in the subsequent period, skills decreased. Despite this, after a period of nine months, they were still higher than those identified before the study. There was a reduction of 18.2% in knowledge in the theoretical test after T1 vs 13.0% after T2 (p < 0.01) and a reduction of 7.6% in skills on the practical test after T1 vs 5.3% after T2 (p < 0.01). Conclusion: Nurses were able to retain more knowledge and skills on cardiopulmonary resuscitation after retraining, which stresses the importance of regular training and continuing education in health.

Background: Health professionals are expected to be competent in cardiopulmonary resuscitation (CPR), thus requiring acquisition and maintenance of knowledge and practice. If time is an important factor associated with the loss of these competencies, acting in CPR situations more frequently may contribute to greater retention. Thus, this study aimed to compare the retention of knowledge and skills in CPR among health professionals in clinical and intensive care after educational intervention. Methods: Intervention, prospective and analytical study. Nursing professionals from the clinical care unit (CCU) and intensive care unit (ICU) received a first theoretical and practical CPR training, called T1, and a retraining nine months later, called T2, being followed for a total period of 18 months. The comparison of the percentage score of knowledge and practice between the evaluations was made by the Wilcoxon test and Friedman's test, considered significant for p<0.05. Results: 56 professionals participated in all stages of the study, 34 CCU professionals and 22 ICU professionals. Soon after T1, the ICU group showed a greater ease of learning (p=0.032), which disappeared after T2, showing a leveling of the groups. Regarding skills, they also reduced with time in a similar way between groups. However, nine months after T2, even reducing practical skills, they were significantly higher in ICU professionals compared to those in the CCU (p=0.018). Knowledge retention nine months after T1 and T2 was similar between groups. However, nine months after T2 the ICU professionals were able to retain more practical skills in CPR (p=0.030). Conclusions: The retraining improved knowledge in both groups in a similar way, but the ICU group retained more practical skills, reinforcing the thesis that a higher frequency of action in CPR situations favors the retention of skills.
