Paracetamol vs ibuprofeno para el dolor de la episiotomía en las 42 horas postparto

Objetivo: Evaluación de la eficacia analgésica para el dolor de la episiotomía entre el paracetamol y el Ibuprofeno, en las primeras 42 horas postparto. Método: Estudio cuasi-experimental (prospectivo y simple ciego) en mujeres que dieron a luz en el HOSPITAL UNIVERSITARIO CENTRAL DE ASTURIAS (OVIEDO), excluyendo alérgicas, patologías asociadas ó aquellas que el idioma impidiese un correcto entendimiento. Dos grupos: 1) Paracetamol 1 gr; 2) Ibuprofeno 600 mg. Tamaño de muestra: 110 por grupo para alcanzar mínimo de 80. Variable principal: grado de dolor según puntuación de escala (0 a 3). Otras variables: edad de paciente, semanas de gestación, peso neonatal, paridad, inicio del parto, anestesia epidural, tipo de parto, desgarro, inflamación y enrojecimiento, hematoma, hemorroides, necesidad de sondaje evacuador, aplicación de hielo y solicitud de analgesia. Tamaño final de la muestra: 88 grupo paracetamol y 97 grupo ibuprofeno. La escala de dolor se midió a las 2 horas postparto (previo al tratamiento) y, posteriormente, cada 8 hasta 42 horas. Se realizó análisis descriptivo y comparación entre grupos. Resultados: No encontramos diferencias significativas en la escala de dolor entre ambos fármacos, ni en los subgrupos analizados, salvo en el subgrupo de partos eutócicos, donde el ibuprofeno fue superior al paracetamol. En el global de la serie, el grupo de paracetamol solicitó hielo y otra medicación con mayor frecuencia que el grupo de ibuprofeno. Conclusiones: El ibuprofeno 600 mg y el paracetamol de 1 gr obtienen una respuesta similar en las primeras 42 horas postparto, si bien el ibuprofeno parece tener algunas ventajas adicionales.

Preliminary interpretation of shaking-table response of a full-scale 3-storey building composed of thin reinforced concrete sandwich walls

In the last few decades, the use of cast in situ reinforced concrete sandwich panels for the construction of low- to mid-rise buildings has become more and more widespread due to several interesting properties of this construction technique, such as fast construction and high thermal and acoustic performances. Nonetheless the level of knowledge of the structural behavior of systems made of squat reinforced concrete sandwich panels is still not so consolidated, especially with reference to the seismic response, due to the lack of experimental studies. In recent years, while various experimental tests have been conducted on single panels aimed at assessing their seismic capacity, only few tests have been carried out on more complex structural systems. In this paper, the experimental results of a series of shaking-table tests performed on a full-scale 3-storey building are presented in detail. The main goal is to give to the scientific community the possibility of develop independent interpretation of these experimental results. An in-depth interpretation of the discrepancies between the analytical predictions and the experimental results is beyond the objective of this paper and is still under development. Nonetheless, preliminary interpretations indicate that both the stiffness and the strength of the building under dynamic excitation appear quite superior with respect to those expected from the results of previous pseudo-static cyclic tests conducted on simple specimens.

How buildings visualise client and architect: The problem that today’s user is typically not the client

An article presented at the last ICAT- conference stated at the end that buildings at all times tend to picture the people who had them erected. This paper aims to show the correctness of that statement. To this end, it will examine a number of typical residential buildings dating from the beginning of the seventeenth century up to today, investigate who had the buildings erected, and relate that to the performance of the buildings. This relation analysis will mainly use the scale but also the degree of diversity in function and appearance as factors. Furthermore, using economic data and data on the buildings to identify patterns, it will investigate how size of the property and relative size of the capital interest behind the building has developed. Since the authors live in Copenhagen and Copenhagen is very typical in its historical development, buildings and environments in and around the centre of Copenhagen are used as examples.
