Plan de Cuidados Estandarizado en Pacientes con Amputación Traumática de Miembro Inferior

La amputación traumática de miembro inferior constituye un proceso complicado de adaptación y superación en el que se producen repercusiones en la persona tanto a nivel físico como psicológico y social. Este tipo de cirugía supone un cambio drástico en la vida de quienes las padecen y sus familias, siendo a menudo adultos jóvenes. En consecuencia, todo el equipo multidisciplinar, pero la enfermera de atención domiciliaria especialmente, juega un papel decisivo a la hora de realizar un seguimiento, estabilizar emocionalmente al paciente e integrarle con el entorno, alcanzando el mayor nivel posible de independencia y autonomía (Modelo de Virginia Henderson). Ésta, garantiza la continuidad de cuidados mediante la supervisión, realización de intervenciones y apoyo a la persona y a la familia, tarea que quizás queda relegada por la actuación inicial de la enfermera hospitalaria. Con el objetivo de brindar unos cuidados integrales y de calidad en el domicilio, se elabora un Plan de Cuidados Estandarizado (PCE) específico para este grupo de pacientes. Se utiliza el Lenguaje Enfermero Estandarizado (LEE) a través de las taxonomías NANDA-NOC-NIC, tal y como se recoge en el Real Decreto 1093/2010 del Boletín Oficial del Estado y se adapta en el 2012 al Boletín Oficial del País Vasco.

The propagation of nerve pulses: From the Hodgkin-Huxley model to the soliton theory

The present project aims to describe and study the nature and transmission of nerve pulses. First we review a classical model by Hodgkin-Huxley which describes the nerve pulse as a pure electric signal which propagates due to the opening of some time- and voltage-dependent ion channels. Although this model was quite successful when introduced, it fails to provide a satisfactory explanation to other phenomena that occur in the transmission of nerve pulses, therefore a new theory seems to be necessary. The soliton theory is one such theory, which we explain after introducing two topics that are important for its understanding: (i) the lipid melting of membranes, which are found to display nonlinearity and dispersion during the melting transition, and (ii) the discovery and the conditions required for the existence of solitons. In the soliton theory, the pulse is presented as an electromechanical soliton which forces the membrane through the transition while propagating. The action of anesthesia is also explained in the new framework by the melting point depression caused by anesthetics. Finally, we present a comparison between the two models.

Alveolar nitric oxide and its role in pediatric asthma control assessment

Resumen Background: Nitric oxide can be measured at multiple flow rates to determine proximal (maximum airway nitric oxide flux; Jaw(NO)) and distal inflammation (alveolar nitric oxide concentration; CA(NO)). The main aim was to study the association among symptoms, lung function, proximal (maximum airway nitric oxide flux) and distal (alveolar nitric oxide concentration) airway inflammation in asthmatic children treated and not treated with inhaled glucocorticoids. Methods: A cross-sectional study with prospective data collection was carried out in a consecutive sample of girls and boys aged between 6 and 16 years with a medical diagnosis of asthma. Maximum airway nitric oxide flux and alveolar nitric oxide concentration were calculated according to the two-compartment model. In asthmatic patients, the asthma control questionnaire (CAN) was completed and forced spirometry was performed. In controls, differences between the sexes in alveolar nitric oxide concentration and maximum airway nitric oxide flux and their correlation with height were studied. The correlation among the fraction of exhaled NO at 50 ml/s (FENO50), CA(NO), Jaw(NO), forced expiratory volume in 1 second (FEV1) and the CAN questionnaire was measured and the degree of agreement regarding asthma control assessment was studied using Cohen's kappa. Results: We studied 162 children; 49 healthy (group 1), 23 asthmatic participants without treatment (group 2) and 80 asthmatic patients treated with inhaled corticosteroids (group 3). CA(NO) (ppb) was 2.2 (0.1-4.5), 3 (0.2-9.2) and 2.45 (0.1-24), respectively. Jaw(NO) (pl/s) was 516 (98.3-1470), 2356.67 (120-6110) and 1426 (156-11805), respectively. There was a strong association (r = 0.97) between FENO50 and Jaw(NO) and the degree of agreement was very good in group 2 and was good in group 3. There was no agreement or only slight agreement between the measures used to monitor asthma control (FEV1, CAN questionnaire, CA(NO) and Jaw(NO)). Conclusions: The results for CA(NO) and Jaw(NO) in controls were similar to those found in other reports. There was no agreement or only slight agreement among the three measure instruments analyzed to assess asthma control. In our sample, no additional information was provided by CA(NO) and Jaw(NO).
