Modelagem do desempenho ambiental dos projetos de exploração e produção aplicando equações estruturais

A legislação ambiental e os principais agentes que se relacionam com a empresa se constituem em fatores exógenos que não podem ser negligenciados ao formular-se e avaliar-se a política ambiental corporativa. As influências exógenas e seus efeitos sobre a gestão ambiental e o gerenciamento de projetos de exploração e produção (E&P) e, por essa via, sobre o desempenho ambiental, foram objetos de estudo desta tese. Embora o desempenho ambiental seja um assunto relevante, a pesquisa sobre esse tema ainda é escassa. Tal carência desponta ainda mais acentuada quando se aborda o desempenho ambiental de projetos na indústria de petróleo e gás. O principal objetivo deste estudo foi avaliar a relação entre a legislação ambiental vigente, as ações de órgãos reguladores, fornecedores, empresas terceirizadas e comunidades locais e o desempenho ambiental dos projetos de E&P na indústria de petróleo e gás e, também, analisar os efeitos do sistema de gestão ambiental e o gerenciamento dos projetos sobre tal desempenho. Na fase abdutiva, foi conduzido um estudo de caso com abordagem qualitativa em uma grande empresa brasileira do setor de petróleo e gás, na fase dedutiva, foi realizada uma pesquisa survey explanatória de corte transversal com abordagem quantitativa, incluindo 113 projetos de E&P de cinco unidades executoras da empresa. Foi formulado um modelo conceitual, com cinco construtos e sete hipóteses de pesquisa, representativo dos efeitos de fatores externos sobre o desempenho ambiental dos projetos de E&P. Os dados foram tratados aplicando a Análise Fatorial Exploratória e a Modelagem de Equações Estruturais com aplicação dos softwares IBM® SPSS® Statistics 20.0 e IBM® SPSS® Amos 18.0. O modelo de equações estruturais foi reespecificado e estimado utilizando o método de Máxima Verossimilhança e o procedimento bootstrap com 2000 reamostragens, até alcançar adequados valores dos índices de ajustamento. O modelo mostrou boa aderência às evidências empíricas, representando uma teoria explicativa dos fatores que influenciam o desempenho ambiental dos projetos de E&P na empresa estudada. As estatísticas descritivas apontaram adequado desempenho dos projetos de E&P com relação aos efluentes descartados, volume de água reutilizada, redução de resíduos e práticas de reciclagem. Identificou-se que projetos de maior porte alcançam melhor desempenho ambiental em relação aos de menor tamanho. Não foram achadas diferenças significativas entre os desempenhos de projetos executados por unidades operacionais distintas. Os resultados da modelagem indicaram que nem a legislação ambiental, nem os agentes externos exercem influência significativa sobre a sistemática da gestão dos projetos de E&P. Os agentes externos atuam sobre a gestão ambiental da empresa exercitando capacidades colaborativas, obstrutivas e propositivas. A legislação ambiental é percebida como entrave ao desenvolvimento dos projetos ao longo de seu ciclo de vida, principalmente, pelas deficiências dos órgãos ambientais. Identificou-se que o sistema de gestão ambiental influencia diretamente o Programa de Desenvolvimento e Execução de Projetos de E&P, que, por sua vez, provoca efeitos diretos e indiretos sobre o desempenho ambiental. Finalmente, comprovou-se que o Sistema de Gestão Ambiental da empresa é determinante para o desempenho ambiental dos projetos de E&P, tanto pelos seus efeitos diretos, como pelos indiretos, estes últimos mediados pela sistemática de gestão dos projetos de E&P

Influência da dor na capacidade funcional de idosos institucionalizados

The aim of this study was to evaluate the pain influence regarding location, intensity and duration over functional capacity in institutionalized elderly (Fundacao Leur Brito). This is a descriptive exploratory study with a transversal design and quantitative approach. The population of the study was composed of 60 elderly, being 50% males with 60 years-old minimum age and 104 years-old maximum age, with mean age 77,6 (?}11,64) years-old. Data was collected by a structured query formulary divided in four parts: 1) Social, health and demographic characterization; 2) Pain related aspects (time and location); 3) Pain evaluation by numeric scale and 4) Functional capacity measured by Barthel Index. It was observed after evaluation by Squared-chi test (x2) statistical significant difference between pain presence and Barthel Index activities: bath (pvalue=0,015), dressing (p-value= 0,041), intimal hygiene transference (p-value=0,001), chair and bed transference (p-value=0,032), walking (p-value=0,010) and go upstairs (p-value=0,008). It was also observed statistical difference between total Barthel score (dependent/independent) and pain presence, p-value<0, 000. Through data obtained by this study, a multiprofessional approach is necessary to proper pain control and maintenance and/or regain of functional capacity, leading to an increase in life quality with more independence and autonomy to elderly

Quali/quantitative characterization of biogas produced in batch digesters supplied with six distinct substrates

Com a finalidade de se analisar quali/quantitativamente o biogás produzido por 6 tipos de substratos, efetuou-se a presente pesquisa no DER/FCAV/UNESP- SP, Brasil. Os substratos utilizados na digestão anaeróbia foram caracterizados como: 1- Esterco de aves de postura (EAP); 2- Esterco de aves de postura triturado (EAPT); 3- Esterco de aves de corte com cama de maravalha (EACM); 4- Esterco de aves de corte com cama de maravalha triturado (EACMT); 5- Esterco de aves de corte com cama de casca de amendoim (EACA), e 6- Esterco de aves de corte com cama de casca de amendoim triturado (EACAT). Dos resultados obtidos, concluiu-se que, em relação à produção acumulada de biogás, o substrato EAPT foi superior aos demais, enquanto EACM apresentou produção acumulada inferior. em geral, os substratos triturados apresentaram maior quantidade de biogás acumulado em relação aos não triturados, exceto o EACAT, com 20,9 m³ inferior ao EACA. O período de produção máxima de biogás teve início entre 45 e 60 dias, começando a decair a partir dos 120 dias. Aos 57 dias após o enchimento dos biodigestores, o gás produzido possuía teores de CH4 superiores a 53%, e a partir dos 99 dias, todos produziram biogás com teores de CH4 superiores a 70%. Os substratos EAP e EAPT apresentaram maiores concentrações de metano no biogás.

Efeito do isolamento térmico de telhado sobre o desempenho de frangos de corte alojados em diferentes densidades

O objetivo deste trabalho foi avaliar o efeito do uso de isolante térmico de telhado instalado como forro sob a cobertura no desempenho de frangos alojados em diferentes densidades (10, 16 e 22 aves/m²) e nas características da cama de aviário em galpão convencional. O experimento foi realizado durante o verão, utilizando 3328 aves da linhagem Hubbard, distribuídas em um delineamento inteiramente casualizado, em um esquema fatorial 3x2 (densidade e sexo), com quatro repetições dentro de cada ambiente. Para a comparação dos ambientes, utilizou-se a análise conjunta. Durante o período experimental, registraram-se dados de temperatura ambiente em vários pontos do galpão e em diversos horários, umidade relativa e carga térmica radiante. O teor de nitrogênio e matéria seca e a temperatura da cama foram determinados. No ambiente com isolante térmico, as temperaturas ambientais médias e a amplitude térmica diária foram menores e a umidade relativa do ar, maior. O desempenho das aves foi melhor no ambiente com isolante térmico, no qual as aves tiveram maior consumo de ração, maior ganho de peso, melhor conversão alimentar, menor mortalidade e maior produção por área. A temperatura retal das aves do ambiente sem isolante térmico foi mais elevada. À medida que se elevou a densidade, a mortalidade aumentou, porém a produção por área foi maior. O uso do isolante não influenciou a produção de cama, mas diminuiu a porcentagem de nitrogênio na cama. Com o aumento da densidade, a produção de cama elevou-se, pelo maior volume de excretas, mas não influenciou sua porcentagem de nitrogênio. O uso do isolante térmico permitiu aumento da densidade de criação dos frangos.

O corpo como matriz pedagógica

The contemporary conjuncture based on the capitalistic knowledge converges to the corporal consciousness that makes us see, feel, taste and hear, be in/to pieces. Disembodied reason legitimate and legislate ways of being and living socially and its development is the dehumanization of human relations causing pain and suffering. The objective of this work is to discuss the body as pedagogical matrix through imagistic/artistic elements: music, painting and literature. Metaphors lead to self knowledge of human subjectivity and approach us to the kaleidoscope of sensitive knowledge and enables learning to learn with the infinite combinations of images, knowledge, feelings and worldviews. The song Memória da Pele comes in the voice of Maria Betânia speak of the memories that are not mine, but are tattooed in me in the memory of skin, singing the memories of a love lived by who tries to forget rationally, but the body insists on remembering. It is password to think about what we are. The short story by Clarice Lispector, entitled Miss Algarve, narrates the life story of an unmarried and virgin woman, and her encounter with an alien called Ixtlan. Until then, she who lived as if every day were a Monday, found herself seduced by the pleasure of having a body in contact with another body, which also allowed her to give visibility to the bodies of others. She had repudiation by the immorality that her body and the other s perspired. The discovery of the body brings important lessons for nursing, involving our body and the others'. The painting the flying bed or Henry Ford Hospital, by Frida Kahlo, is our final metaphor. The traumatic experience of abortion is shown in this painting trough the picture of the artist naked in a hospital bed. This painting invites us to reflect on our work process. We need to think in multiple dimensions of the being and accept the invitation of art, so that the lightness confronts us with the weight imposed by the hegemonic ideology. I believe it is not a single view, but the many views that should justify the knowledge and practices of nursing; what matters is that they are woven into the dialogue, democracy, provided that protagonism of those individuals involved in this process, in the wandering and uncertainty, in the rewiring, solidarity, plurality. To this end, the body must be the great pedagogue that is able to be viewed not as a tapestry seen by the right view, as the logical knowledge sees, but seen by the opposite side in its singular, irregular, discontinuous weavings

Úlceras de pressão: um estudo com pacientes de unidade de terapia intensiva

To characterize patients according to gender, age category, internment time, diagnostical hypothesis and location of the pressure ulcer; to identify the susceptibility conditions, intrinsical and extrinsical factors present on ICU patients and to verify on the existence of association between the susceptibility conditions and the intrinsecal and extrinsecal factors on the occurrence of PU. Methods: It is a descriptive study, of longitudinal design of the panel type, with quantitative approach, performed on two ICU s of a private hospital located in Natal/RN, with 40 patients interned at these units. The data collection was performed on all three shifts through a structured observation and physical exam of the patients' skin form seeking to identify the presence of PU. Results: The greatest occurence of PU was on individuals of the male gender (70%) when compared to the female gender (30%), that difference being statistically significant (p=0,0267), with the male gender presenting 4,3 times greater chance of developing PU than the female; the predominant age category was from 60 years of age on (85%), 60,0% presented 1 to 2 PU s after 7 (seven) days of permanence in the ICU s, the predominant diagnostical hypothesis on the patients with PU were the respiratory diseases (42,3%) and the most frequent locations of PU were the sacral region (40,0%) and heels (36,0%). 25 PU s of stage I were diagnosed on 50,0% of the followed patients, with general incidence of 50,0% on both ICUs. from the 88 variables researched, 75 were identified on the patients from the study, being the predominant conditions (anemia, hypotension, leukocytosis, other diseases hypertension blood pressure, cardiac insuffience, pneumonia - and ansiolythic), the intrinsecal factors (diminished muscular strenght and/or mass, discrete edema, totally compromised mobile coordination and total inability for movement on the bed) and the extrinsecal factors (inadequate mattress type, permanence on a single position for >2 hours, shearing/friction force, bed clothes with folds that leave marks on the body, pressure force) predominated on patients with PU. The male gender variables (p=0,0267,OR=4,3), sedation (p=0,0006,OR=4,1), psychomotive agitation (p=0,0375,OR=5,8) and leukocytosis (p=0,0285,OR=5,0) presented a significant statistical diference when analyzed independently. We verified an association of 17,3%, statistically significant (p=0,0384), between the susceptibility conditions (anemia, leukocytosis and hypotension), the intrinsecal factors (age equal or above 60 years, diminished/absent pain sensibility and smooth, fine or delicate skin) and the extrinsecal factors (inadequate mattress, pressure forces, shearing/friction force, permanence on a single position for more than 2 hours, elevation between 30 to 45 degrees and inadequate bed clothes' conditions), with a chance ratio of 4,6 times the risk of occurrence of PU on the patients that presented the referred association. Conclusion: The incidence of PU detected on the ICU-interned patients was high and we made evident the existence of association between the susceptibility conditions, the intrinsecal and extrinsecal factors on the occurrence of PU s on the ICUinterned patients, and thus we accept the alternative hypothesis proposed on the study

Mananoligossacarídeos e complexo enzimático em dietas para frangos de corte

Avaliou-se o efeito de dietas com mananoligossacarídeos e complexo enzimático (CE) sobre o desempenho, a morfologia intestinal e a qualidade da cama de frangos aos 42 dias de idade. Foram utilizadas 750 aves em delineamento inteiramente casualizado em esquema fatorial 2 × 2 + 1, com dois níveis de mananoligossacarídeos (0 e 0,1% de 1 a 21 dias e 0,05% de 22 a 42 dias de idade), dois níveis de complexo enzimático (0 e 0,05%) e uma dieta com antibióticos (CP), totalizando cinco dietas com cinco repetições. Aos 42 dias de criação, o desempenho foi avaliado e, após o abate das aves, foram coletadas amostras de intestino e de cama e avaliado o desempenho. A inclusão de mananoligossacarídeos e/ou complexo enzimático na dieta não afetou o desempenho das aves, o perímetro e a altura dos vilos duodenais, a profundidade de criptas, a densidade de vilos no duodeno, jejuno e íleo, os teores de matéria seca e nitrogênio total e o pH das camas. A interação mananoligossacarídeos × complexo enzimático foi significativa para perímetro e altura de vilos no jejuno, que foram maiores nas aves alimentadas com as rações sem complexo enzimático e mananoligossacarídeos, mesmo comportamento observado para perímetro e altura de vilos ileais. Entretanto, quando adicionados mananoligossacarídeos e complexo enzimático, os valores dessas variáveis reduziram. A volatilização de amônia aumentou em camas de frango tratados com antibióticos e diminuiu com a adição de mananoligossacarídeos à dieta. A adição de mananoligossacarídeos ou complexo enzimático às dietas aumentou o perímetro e altura de vilos da mucosa do jejuno e do íleo e reduziu a volatilização de amônia da cama.

Fontes de Sódio e Relação Sódio: Cloro para Frangos de Corte

Foram utilizados 2.880 pintos de corte, para avaliar os efeitos de diferentes fontes de sódio (Na+) e relações sódio:cloro (Na+:Cl-) na ração. As aves receberam ração e água ad libtum. O delineamento experimental foi inteiramente casualizado, com quatro tratamentos e seis repetições. O ganho de peso, consumo de ração, conversão alimentar e mortalidade não foram influenciados (p>0,05) pela substituição da fonte tradicional de Na e pelas diferentes relações Na:Cl. A umidade da cama foi afetada pela fonte e níveis de Na na ração. Os resultados mostraram que pode-se utilizar o NaHCO3 como fonte parcial à exigência de Na para frangos de corte de 1 a 47 dias de idade.

Aplicação de tensoativos não iônicos na recuperação de fluidos de perfuração poliméricos

The drilling fluid used to assist in the drilling operation of oil wells, accumulates solids inherent in the formation as it is circulated in the well, interfering in the fluid performance during operation. It is discarded after use. The disposal of these fluids causes one of the most difficult environmental problems in the world. This study aims to promote liquid phase separation of drilling fluids, which have circulated in oil wells, and enable this recovered liquid to formulate a new fluid. For this, non-ionic surfactants were used in order to select the best outcome in phase separation. Five real water-based drilling fluids were utilized, which were collected directly from the fields of drilling oil wells, classified as polymeric fluids. The methodology used consisted in combining the fluid with surfactant and then subjecting it to a process of centrifugation or decantation. The decantating tests were scheduled through experimental planning 23 and 32, using as variables the percentage (%) of surfactant utilized and the stirring time in minutes. The surfactants used were ethoxylated nonylphenol and lauryl alcohol ethoxylated with different degrees of ethoxylation. Phase separation was monitored first by tests of stability, and subsequently by the height of the interface in beakers of 100 mL. The results showed that from the surfactants studied, the lauryl alcohol ethoxylated with 3 ethoxylation units has been the most effective in the phase separation process of the drilling fluids tested. The statistical tool used was of great industrial value regarding the programming phase separation in drilling fluids. In conclusion, the liquid phase separated using surfactant can be reused for a new formulation of drilling fluid with similar properties of a new fluid, assuring its efficiency. And in the resulting analysis it is also suggested that the adsorption is the mechanism that leads the phase separation, with surfactant adsorbing in the active solids

Investigação da relação entre conteúdo onírico e aprendizado de uma tarefa cognitiva complexa

Several lines of evidence indicate that sleep is beneficial for learning, but there is no experimental evidence yet that the content of dreams is adaptive, i.e., that dreams help the dreamer to cope with challenges of the following day. Our aim here is to investigate the role of dreams in the acquisition of a complex cognitive task. We investigated electroencephalographic recordings and dream reports of adult subjects exposed to a computer game comprising perceptual, motor, spatial, emotional and higher-level cognitive aspects (Doom). Subjects slept two nights in the sleep laboratory, a completely dark room with a comfortable bed and controlled temperature. Electroencephalographic recordings with 28 channels were continuously performed throughout the experiment to identify episodes of rapid-eye-movement (REM) sleep. Behaviors were continuously recorded in audio and video with an infrared camera. Dream reports were collected upon forced awakening from late REM sleep, and again in the morning after spontaneous awakening. On day 1, subjects were habituated to the sleep laboratory, no computer game was played, and negative controls for gamerelated dream reports were collected. On day 2, subjects played the computer game before and after sleep. Each game session lasted for an hour, and sleep for 7-9 hours. 9 different measures of performance indicated significant improve overnight. 81% of the subjects experienced intrusion of elements of the game into their dreams, including potentially adaptative strategies (insights). There was a linear correlation between performance and dream intrusion as well as for game improval and quantity of reported dreaming. In the electrophysiological analysis we mapped the subjects brain activities in different stages (SWS 1, REM 1, SWS 2, REM 2, Game 1 and Game 2), and found a modest reverberation in motor areas related to the joystick control during the sleep. When separated by gender, we found a significant difference on female subjects in the channels that indicate motor learning. Analysis of dream reports showed that the amount of gamerelated elements in dreams correlated with performance gains according to an inverted-U function analogous to the Yerkes-Dodson law that governs the relationship between arousal and learning. The results indicate that dreaming is an adaptive behavior

Caracterização do ciclo sono/vigília de professores do ensino médio em natal/rn

In the school environment is fundamental the knowledge about the sleep-wake cycle (SWC), because we find children and adolescents with excessive sleepiness and learning difficulties. Furthermore, teachers with high demand and with different work schedule, which may contribute to changes in SWC. The aim of this study was to describe the SWC of high school teachers in Natal/RN. Habits and knowledge about sleep, chronotype, SWC, daytime sleepiness, sleep quality and job satisfaction were described in 98 high school teachers from public and private school. These parameters were compared according to the characteristics of work, family structure and gender. Data collection was performed with the use of questionnaires in two stages: 1) "health and sleep" (general characterization of sleep habits), Horne & Ostberg questionnaire (characterization of chronotype), Epworth Sleepiness Scale and the Index of Pittsburg Sleep Quality, 2) The sleep diary for 14 days. From the results, we observe that the teachers woke up and went to bed earlier in the week and showed a reduction of time in bed around 42min comparing to weekend. This reduction in time in bed during the week was accompanied by an increase in nap duration on weekend. In addition the teachers woke up earlier on Saturdays than on Sundays, probably due to housework and leisure. The teachers' knowledge about sleep was low in relation to individual differences and effect of alcoholic beverages on sleep, and high in the consequences of sleep deprivation. The differences found in comparisons on the characteristics of work, family structure and gender were punctual, except concerning the work schedule. The teacher who started work in the morning and finished in the night, woke up earlier, went to bed later and had less time in bed, when compared to teachers who work only in two shifts. In addition, teachers with late chronotypes who begin the work in the morning had a greater irregularity in the wake up time compared to teachers with earlier and intermediate chronotypes. Half of teachers have excessive sleepiness, which was positive correlated with work dissatisfaction. In general, teachers showed IPSQ averages equivalent to poor sleep quality and the women showed worst averages. From the results, it is suggested that the SWC of teachers varies according to work schedule, leading to irregularity and partial sleep deprivation in the week, although these responses vary according to chronotype. These changes are accompanied by excessive daytime sleepiness and poor sleep quality. However, it is necessary to expand the sample to clarify the influence of variables related to work, family structure and gender together

Avaliação do padrão do ciclo sono-vigília e a cognição em estudantes de medicina com diferentes esquemas de horários de aulas

The sleep patterns of students entering the university, is accompanied by many factors that can lead to changes in sleep habits, such as academic demands, new social opportunities, reduced parental care and irregular teaching schedules. The irregular pattern of sleep-wake cycle is usually accompanied by several daytime consequences, for example, reduced levels of motivation, performance, concentration, alertness and mood as well as increased fatigue and sleepiness.Thus, there are numerous reasons to support the fact that these students may suffer damage in their academic performance. The aim of this study was to evaluate the sleep-wake cycle (SWC) and cognition in medical students with different schemes teaching schedules. One group started classes at 08am, while the other started at 07am. We analyzed the data from 88 volunteers, 39 from each group. However, only those who participated in both stages of the study (n = 78) underwent cognitive testing. For subjective evaluation of the SWC was used questionnaires to check the quality of sleep, chronotype, daytime sleepiness and sleep habits. For objective evaluation was used actigraphy. For cognitive assessment was used the test MoCA (Montreal Cognitive Assessment). The results indicate that the group has class earlier had a greater irregularity of the SWC and a worse performance in cognitive testing. There was a difference between the schedules the week and weekend in the subjective variables, bedtime, wake up and sleep duration in both groups. The objective variables, time in bed showed difference between the schedules the week and weekend to the group started class at 08am and the variables bedtime, get up time, actual sleep time, time in bed and wake bouts in the class at 07am. In the cognitive test, there were differences between the groups in overall score and in the areas of executive function and memory recall. Thus, it is suggested that the class starting time may cause irregularity of the SWC and the irregularity may cause mild cognitive impairment. Moreover, cognitive testing MoCA was sensitive to detect differences among students, although the difference between the schedules is small

Utilização de microemulsão na remoção da cor de efluentes têxteis contendo corantes dispersos

Polyester fibers are the most used fibers in the world and disperse dyes are used for dyeing these fibers. After dyeing, the colorful dyebath is discharged into effluent streams, which needs a special treatment for color removal. Surfactants interaction with dyes has been evaluated in several studies, including the textile area, specifically in the separation of dyes from textile wastewater. In this work a cationic surfactant was used in a microemulsion system for the extraction of anionic dyes (disperses dyes) from textile wastewater. These microemulsion system was composed by dodecylamonium chloride (surfactant), kerosene oil (organic phase), isoamyl alcohol (cosurfactant) and the wastewater (aqueous phase). The wastewater that results after the dyeing process is acid (pH 5). It was observed that changing the pH value to above 12.8 the extraction could be made, resulting in an aqueous phase with low color level. The Scheffé net experimental design was used for the extraction process optimization, and the obtained results were evaluated using the program "Statistica 7.0". The optimal microemulsion system was composed by 59.8wt.% of wastewater, 30.1wt.% of kerosene, 3.37wt.% of surfactant and 6.73wt.% of cosurfactant, providing extraction upper than 96%. A mix of reactive dyebath (50%) and disperse dyebath (50%) was used as aqueous phase and it presented extraction upper than 98%. The water phase after extraction process can be reused in a new dyeing, being obtained satisfactory results, according to the limits established by textile industry for a good dyeing. Tests were accomplished seeking to study the influence of salt addition and temperature. An experimental design was used for this purpose, which showed that the extraction doesn't depend on those factors. In this way, the removal of color from textile wastewater by microemulsion is a viable technique (that does not depend of external factors such as salinity and temperature), being obtained good extraction results even with in wastewater mixtures

Comunicação em saúde: algumas reflexões a partir da percepção de pacientes acamados em uma enfermaria

Investigam-se imagens e significados sobre experiências vivenciadas por pacientes no processo de atendimento/tratamento em uma enfermaria, visando problematizar questões éticas no cotidiano das práticas de saúde, que possam contribuir para refletir, no espaço da formação profissional, sobre situações que, muitas vezes, se naturalizam pela urgência da rotina. O trabalho consistiu em entregar câmaras fotográficas a cinco pacientes acamados, internados em uma Enfermaria de Ortopedia de um hospital universitário, no segundo semestre do ano de 2001, para que registrassem, pela fotografia, experiências que vivenciavam na condição de pacientes, procurando responder às perguntas: o que significa estar na cama sem poder sair dela? O que é bom e o que é ruim em sua rotina na Enfermaria? Buscando compreender o material pela ótica dos pacientes, apresenta-se aqui parte da experiência registrada e relatada. Os resultados obtidos apontam que entre as maiores dificuldades enfrentadas pelos pacientes entrevistados estão a dependência, gerando constrangimento e desconforto, e a falta de informação, gerando insegurança e ampliando a dependência.

Caracterização das quedas de pacientes segundo notificação em boletins de eventos adversos

Este estudo foi desenvolvido com o objetivo de caracterizar as quedas de pacientes internados ocorridas em hospital terciário. Foram analisados 826 Boletins de Notificação de Eventos Adversos, de um período de 30 meses, que registraram 0,30 quedas por 1000 pacientes/dia. Quedas do leito foram mais frequentes (55%), com maior prevalência na enfermaria de neurologia. Maior frequência de quedas foi verificada no período noturno (63,7%), nos primeiros cinco dias da admissão (61,7%), nos pacientes de sexo masculino (57,5%) e na faixa etária maior de 60 anos (50%). Nos casos de quedas do leito, os diagnósticos relacionaram-se a doenças infecciosas e parasitárias (18,2%), doenças do sistema nervoso (18,2%) e doenças do aparelho circulatório (13,7%). Nas quedas da própria altura, os diagnósticos relacionaram-se a neoplasias (19,4%) e doenças do aparelho geniturinário (16,1%). A caracterização desses eventos adversos auxilia no reconhecimento dos grupos de maior risco e na elaboração de propostas preventivas.
