A segurança do paciente e a avaliação do risco de quedas / Patient safety and fall-risk assessment / Seguridad del paciente y evaluación de riesgo de caída

Objetivo: Avaliar os pacientes hospitalizados quanto ao risco de quedas. Métodos: Estudo transversal, realizado por meio da aplicação da escala de Morse e registros de prontuários. Realizou-se estatísticas descritivas e Teste Qui-quadrado de Pearson, adotando-se o nível de 5%. Resultados: Dos 244 participantes, 139 (57%) eram do sexo masculino, 86 (47,5%) idosos, 116 (47,5%) com companheiro, 112 (45,9%) pardos e 173 (70,9%) com baixa escolaridade. O risco de quedas foi associado ao histórico de quedas (p=0,000), diagnóstico secundário (p<0,001), deambulação (p=0,002), marcha (p<0,001) e estado mental (p<0,000). A maioria dos entrevistados 194 (79,5%) estão sob um risco moderado a alto de sofrer quedas da própria altura 37 (15,2%), ocorridas no quarto ou na enfermaria 38 (15,6%). Conclusão: Observou-se um risco moderado a alto para quedas nos pacientes hospitalizados, o que aponta para a necessidade de implementação de políticas de segurança do paciente para garantir a qualidade da assistência.

Objective: Assess hospitalized patients for the risk of falls. Methods: Cross-sectional study, carried out through the application of the Morse scale and medical records. Descriptive statistics and Pearson's Chi-square test were performed, adopting the 5% level. Results: Of the 244 participants, 139 (57%) were male, 86 (47.5%) elderly, 116 (47.5%) with a partner, 112 (45.9%) brown and 173 (70.9%) with low education level. The risk of falls was associated with a history of falls (p = 0.000), secondary diagnosis (p <0.001), walking (p = 0.002), gait (p <0.001) and mental status (p <0.000). Most respondents 194 (79.5%) are at moderate to high risk of suffering falls from their own height 37 (15.2%), in their bedroom or in the ward 38 (15.6%). Conclusion: There was a moderate to high risk for falls in hospitalized patients, which points to the need of implementing patient safety policies in order to guarantee quality of care. (AU)

Se realizaron estadísticas descriptivas y la prueba de Chi-cuadrado de Pearson, adoptando el nivel del 5%. Resultados: De los 244 participantes, 139 (57%) eran hombres, 86 (47.5%) ancianos, 116 (47.5%) con una pareja, 112 (45.9%) marrones y 173 (70.9%) con baja educacion. El riesgo de caídas se asoció con antecedentes de caídas (p = 0.000), diagnóstico secundario (p <0.001), caminar (p = 0.002), marcha (p <0.001) y estado mental (p <0.000). La mayoría de los encuestados 194 (79.5%) tienen un riesgo moderado a alto de sufrir caídas desde su propia altura 37 (15.2%), ocurriendo en el dormitorio o en la sala 38 (15.6%). Conclusión: Hubo un riesgo moderado a alto de caídas en pacientes hospitalizados, lo que apunta a la necesidad de implementar políticas de seguridad del paciente para garantizar la calidad de la atención.

Intra-dorsal periaqueductal gray administration of cannabidiol blocks panic-like response by activating 5-HT1A receptors.

Activation of 5-HT1A receptors in the dorsal periaqueductal gray (dPAG) impairs escape behavior, suggesting a panicolytic-like effect. Cannabidiol (CBD), a major non-psychotomimetic compound present in Cannabis sativa, causes anxiolytic-like effects after intra-dPAG microinjections by activating 5-HT1A receptors. In the present work we tested the hypothesis that CBD could also impair escape responses evoked by two proposed animal models of panic: the elevated T-maze (ETM) and electric stimulation of dPAG. In experiment 1 male Wistar rats with a single cannula implanted in the dPAG received a microinjection of CBD or vehicle and, 10 min later, were submitted to the ETM and open field tests. In experiment 2 escape electrical threshold was measured in rats with chemitrodes implanted in the dPAG before and 10 min after CBD microinjection. In experiment 3 similar to experiment 2 except that the animals received a previous intra-dPAG administration of WAY-100635, a 5-HT1A receptor antagonist, before CBD treatment. In the ETM microinjection of CBD into the dPAG impaired inhibitory avoidance acquisition, an anxiolytic-like effect, and inhibited escape response, a panicolytic-like effect. The drug also increased escape electrical threshold, an effect that was prevented by WAY-100635. Together, the results suggest that CBD causes panicolytic effects in the dPAG by activating 5-HT1A receptors.
