No caleidoscópio o estresse da equipe de enfermagem da UTI de um Hospital Universitário em Natal-RN

This study aimed to analyze stress on nursing staff of intensive care at the Teaching Hospital Onofre Lopes. The study sample consisted of thirty-eight (38) nursing professionals, including technicians and nurses working in the ICU of the hospital Data were collected between September to November 2011 in two stages.The first was the application of the Lipp Stress Symptoms Inventory (LSSI), which allowed us to measure the stress phase in which each team member was. After that, data were tabulated in Microsoft Excel spreadsheets and analyzed according to the 2010 inventory guidelines proposed by the author. After this analysis it was possible to complete the second phase of the research, which consisted of a semi-structured interview designed for those workers who were in the second phase of stress, resistance. Data analysis was based on Bardin 2004 content analysis, enabling the creation of categories based on grouping the ideas present in the interviewees' statements. It was found that the study population was mostly female (78.9%) aged from 30 to 39 years (50%), married (52.3%) and with dual-employment (65.7%). The most predominant phase, according to the Lipp inventory, was the stress resistance, present in 44.7% of the team and having as most predominant physical symptoms the constant feeling of physical exhaustion, verified in 16.8% of the participants, and psychological, the excessive irritability and emotional sensitivity in 26.3%. Regarding the qualitative data it was possible to establish three categories and four subcategories, with the following categories: the stressors of the workplace, overwork and the interpersonal relationships of the nursing staff in the ICU. And as subcategories: Routine care in the ICU; Pressures and Individual Charges; double journey: professional reflections on daily life, the night shift nursing staff and the body suffers, the manifestations of stress; deficient communication between team members. Thus, this study allowed the visualization of the stress phenomenon on nursing staff of the Teaching Hospital Onofre Lopes as a kaleidoscope of thoughts, feelings and experiences perceived by these professionals in different areas of their lives. It was also verified that the strengthening of the stress theme among nursing professionals need to be exploited and stimulated in several nursing areas of discussion so these workers are encouraged to take better care of themselves so they can take care of others health

Qualidade de sono e qualidade de vida em trabalhadores submetidos a diferentes esquemas de trabalho de uma empresa petroquímica

One of the largest problems of the present time resulting from the economic globalization and the modern technology, of the point of view of the biological rhytms of our organism, it is offering services and production of goods available in 24 o'clock, that it demands organized workers in several work schedules besides the hours of the day. Those schedules cause a series of biopsychosocial consequences in the worker's health, in function of circadian, homeostatic and psychosocial alterations. Accordingly, the aim of this study was to accomplish an evaluation of the effects of several works schedules in the pattern of the sleep wake cycle, anxiety, stress and in the health. We counted with a sample of 274 workers subdivided in 49 daytime worker groups and 225 workers in different shift work schedules with different speeds (rotating shift group, slower day shift group, faster day shift group). From the results analysis it is verified irregularities of the daily activities, stress and alterations in the workers' health in all schedules. It was also verified thata the workers thata presented irregularities in the daily activities were the mroe stressed. On the other hand, the shift works were considered more ansious and associated with bad sleep quality. It was verified that the workers with bad sleep quality were those presented larger levels of dispocional anxiety. There was no statistically significant correlation between bad sleep quality and irregular daily lifestyle. However, it can be affirmed thata shift work schendules doesn't are the main determinant for the circadian alterations, but the answers of the individuals to the shifts work; and that the inadequate behavioural strategies to work with the effects of the shift schedules. In conclusion, individual strategies related to the coping of the work in shift (adaptation and tolerance) should be extolled as indispensable tool in the ergonomic evaluation of the work

O efeito da dessincronização circadiana sobre o metabolismo

The lost of phase relationship between rhythms and behaviour can, and often do, undesirable consequences. The purpose os study was to ascertain the effect of circadian desynchronization in T22 about metabolism of wistar rats. The subjects consisted of 24 animals separated in two groups: control (n=12) T24 with 8 weeks of aged and experimental group (n=12) T22, also with 8 weeks of aged. Both the groups were subject to register of locomotor actitivity, body temperature, body weight and food intake in all the experiment. And more, both the groups were subject to food deprivation, running in treadmill and forced swimming. The results show rhythm of locomotor activity and body temperature desynchronized. Dont exist diference in body weight between both the groups (T24 = 386,75±40,78g e T22 380,83±44,28g) . However, the food intake was different between the phases, light and dark, in intergroup and intragroup. The body temperature was not different in food deprivation. The same ocurred for running in treadmill and forced swimming. Since similar alterations occur in shift workers, it is proposed that the experimental paradigm presented in this manuscript is a useful model of shift work. That is, alterations in activity/rest cycles and consummatory behavior can affect the health of organism

Percepção dos efeitos do trabalho em turnos sobre a saúde e a vida social em funcionários da enfermagem em um hospital universitário do Estado de São Paulo

O trabalho em turnos existe desde o início da vida social dos homens, sendo utilizado em diferentes setores, como na indústria de produção de bens de consumo e de serviços. A área da saúde exige o sistema em turnos para manutenção de atividades durante 24 horas. Teve-se como objetivo identificar os sistemas de turnos em funcionários de enfermagem em um hospital universitário, avaliar a percepção sobre os prováveis efeitos do trabalho em turnos em sua saúde e vida social e o grau de participação desses funcionários na forma de organização de sua jornada. Trata-se de uma pesquisa descritiva e exploratória, cujos resultados foram obtidos mediante questionário aplicado a 348 funcionários da enfermagem do Hospital de Clínicas da Faculdade de Medicina de Botucatu, São Paulo. Dentre os resultados, observou-se que, em sua maioria, eles tinham menos de 40 anos, eram casados, do sexo feminino, com um filho pelo menos, cumprindo uma escala de turnos alternados, com freqüência de revezamento superior a quinze dias e referindo queixas de caráter neuro-psíquico, gastrintestinal e cardiovascular. Houve ainda queixas sobre relacionamento e tempo de convivência. Na maioria das vezes, era pouca a participação do funcionário na forma de organização de sua escala de trabalho.

Eventos adversos em terapia medicamentosa em Unidade de Terapia Intensiva - UTI

Due to the complexity and instability of clinical conditions of ICU patients, the drug therapy applied in this type of environment requires a combination of several prescribed drugs, which is a favorable condition for drug interaction, toxic synergism and possible iatrogenia. In the possible universe of ICU occurrences, this study aimed at identifying and evaluating the incidence of adverse events in drug therapy at the Intensive Care Therapy Service (SETI) in wards I and II. It is a cross-sectional, descriptive, prospective and quantitative study conducted from August to September, 2011 in the Intensive Care Service of the Botucatu School of Medicine University Hospital - UNESP. The population consisted of fifteen clinical nurses, including those in the Improvement and Volunteer Internship Programs, who contributed to the investigation after signing an informed consent form and according to approval by the Research Ethics Committee number 10711/CE - FMB. The data were entered on a form and analyzed. Results showed that, on average, 8.9% of events/day occurred, and the highest frequency was observed on August 04, 2011. 63% and 22% were respectively observed in the morning and afternoon shifts, and 15% in the night shift. 48% of these were due to administration time errors, followed by drug prescription and dispensation errors, with percentages of 22% and 18%, respectively. Antibiotics showed the highest frequency of adverse events - 18%, which was followed by 13% for anticoagulant, 11% for antiemetic and 10% for antiulcerative drugs. As regards the occurrence of adverse events related to hospitalization time, the highest frequency occurred in patients who were hospitalized for 10 days. Concerning the ratio between reported events and the number of items in the prescription, the highest frequency of events was related to prescriptions with 20 items...

Qualidade de vida do trabalhador de enfermagem de um hospital Estadual

The search for quality of life (QOL) is now an ideal among thousands of people worldwide and is currently the subject has been studied in different areas of knowledge. Thus, one can perceive it in different dimensions, each with its due importance to people's lives. The verification of quality indexes of work life (QWL) may provide information on factors that directly interfere with the satisfaction and personal motivation and collective, with reflections on the structure and excellent service. To this end, we carried out a study to know the characacteristics of quality of life of nursing professionals in a state hospital in São Paulo State, based on short range of quality of life of the World Health Organization (WHOQOL-BREF). This work is a study with a quantitative approach, cross-sectional descriptive and exploratory data analysis using descriptive statistics, involving a sample of 281 nurses who answered the scale for measuring quality of life, composed of four areas: physical, psychological, social relationships and environment. In the study, these areas were related to the professional position, and shift work. There was a satisfactory quality of life in the study population in different areas of WHOQOL-BREF. There was no statistically significant changes in quality of life among the variables. It follows that the population presented data consistent with an adequate quality of life, thus making relevant to addressing the quality of life of nursing in a healthcare organization which has as fundamental to the pursuit of quality through the accreditation process second hospital established by the National Accreditation Organization (ONA) that aims at establishing and implementing a process of improving health care, thereby stimulating the services to achieve higher standards of quality

Forced Desynchronization of Activity Rhythms in a Model of Chronic Jet Lag in Mice

We studied locomotor activity rhythms of C57/Bl6 mice under a chronic jet lag (CJL) protocol (ChrA(6/2)), which consisted of 6-hour phase advances of the light-dark schedule (LD) every 2 days. Through periodogram analysis, we found 2 components of the activity rhythm: a short-period component (21.01 +/- 0.04 h) that was entrained by the LD schedule and a long-period component (24.68 +/- 0.26 h). We developed a mathematical model comprising 2 coupled circadian oscillators that was tested experimentally with different CJL schedules. Our simulations suggested that under CJL, the system behaves as if it were under a zeitgeber with a period determined by (24 -[phase shift size/days between shifts]). Desynchronization within the system arises according to whether this effective zeitgeber is inside or outside the range of entrainment of the oscillators. In this sense, ChrA(6/2) is interpreted as a (24 - 6/2 = 21 h) zeitgeber, and simulations predicted the behavior of mice under other CJL schedules with an effective 21-hour zeitgeber. Animals studied under an asymmetric T = 21 h zeitgeber (carried out by a 3-hour shortening of every dark phase) showed 2 activity components as observed under ChrA(6/2): an entrained short-period (21.01 +/- 0.03 h) and a long-period component (23.93 +/- 0.31 h). Internal desynchronization was lost when mice were subjected to 9-hour advances every 3 days, a possibility also contemplated by the simulations. Simulations also predicted that desynchronization should be less prevalent under delaying than under advancing CJL. Indeed, most mice subjected to 6-hour delay shifts every 2 days (an effective 27-hour zeitgeber) displayed a single entrained activity component (26.92 +/- 0.11 h). Our results demonstrate that the disruption provoked by CJL schedules is not dependent on the phase-shift magnitude or the frequency of the shifts separately but on the combination of both, through its ratio and additionally on their absolute values. In this study, we present a novel model of forced desynchronization in mice under a specific CJL schedule; in addition, our model provides theoretical tools for the evaluation of circadian disruption under CJL conditions that are currently used in circadian research.

Maternal Melatonin Programs the Daily Pattern of Energy Metabolism in Adult Offspring

Background: Shift work was recently described as a factor that increases the risk of Type 2 diabetes mellitus. In addition, rats born to mothers subjected to a phase shift throughout pregnancy are glucose intolerant. However, the mechanism by which a phase shift transmits metabolic information to the offspring has not been determined. Among several endocrine secretions, phase shifts in the light/dark cycle were described as altering the circadian profile of melatonin production by the pineal gland. The present study addresses the importance of maternal melatonin for the metabolic programming of the offspring. Methodology/Principal Findings: Female Wistar rats were submitted to SHAM surgery or pinealectomy (PINX). The PINX rats were divided into two groups and received either melatonin (PM) or vehicle. The SHAM, the PINX vehicle and the PM females were housed with male Wistar rats. Rats were allowed to mate and after weaning, the male and female offspring were subjected to a glucose tolerance test (GTT), a pyruvate tolerance test (PTT) and an insulin tolerance test (ITT). Pancreatic islets were isolated for insulin secretion, and insulin signaling was assessed in the liver and in the skeletal muscle by western blots. We found that male and female rats born to PINX mothers display glucose intolerance at the end of the light phase of the light/dark cycle, but not at the beginning. We further demonstrate that impaired glucose-stimulated insulin secretion and hepatic insulin resistance are mechanisms that may contribute to glucose intolerance in the offspring of PINX mothers. The metabolic programming described here occurs due to an absence of maternal melatonin because the offspring born to PINX mothers treated with melatonin were not glucose intolerant. Conclusions/Significance: The present results support the novel concept that maternal melatonin is responsible for the programming of the daily pattern of energy metabolism in their offspring.

Irregular working times and metabolic disorders among truck drivers: a review

A number of studies to better understand the complex physiological mechanism involved in regulating body weight have been conducted. More specifically, the hormones related to appetite, leptin and ghrelin, and their association to obesity have been a focus of investigation. Circadian patterns of these hormones are a new target of research. The behaviour of these hormones in individuals subject to atypical working times such as shiftwork remains unclear. Shiftwork is characterized by changes in biological rhythms and cumulative circadian phase changes, being associated with high rates of obesity and metabolic syndrome. Truck drivers, who work irregular shifts, frequently present a high prevalence of obesity, which might be associated with work-related factors and/or lifestyle. In this context, the aim of this paper was to discuss the relationship of body mass index, appetite-related hormones and sleep characteristics in truck drivers who work irregular shifts compared with day workers.

Desigualdades de género en salud laboral en España

Objetivos: Analizar las desigualdades de género en las condiciones de empleo, trabajo, conciliación de la vida laboral y familiar, y en los problemas de salud relacionados con el trabajo en una muestra de la población ocupada en España en el año 2007 teniendo en cuenta la clase social y el sector de actividad. Métodos: Las desigualdades de género se analizaron mediante 25 indicadores en los 11.054 trabajadores entrevistados en la VI Encuesta Nacional de Condiciones de Trabajo. Se calcularon las odds ratio (OR) y sus intervalos de confianza del 95% (IC95%) mediante modelos de regresión logística multivariados, estratificando por clase social ocupacional y sector de actividad. Resultados: Más mujeres que hombres trabajaban sin contrato (OR = 1,83; IC95%: 1,51-2,21), con alto esfuerzo o baja recompensa (1,14:1,05-1,25) y sufriendo acoso sexual (2,85:1,75-4,62), discriminación (1,60:1,26-2,03) y más dolores osteomusculares (1,38:1,19-1,59). Más hombres que mujeres trabajaban a turnos (0,86:0,79-0,94), con altos niveles de ruido (0,34:0,30-0,40), altas exigencias físicas (0,58:0,54-0,63) y sufriendo más lesiones por accidentes de trabajo (0,67:0,59-0,76). Las trabajadoras no manuales mostraron trabajar con un contrato temporal (1,34:1,09-1,63), expuestas a más riesgos psicosociales y sufriendo mayor discriminación (2,47:1,49-4,09) y enfermedades profesionales (1,91:1,28-2,83). En el sector de la industria las desigualdades de género fueron más marcadas. Conclusiones: En España existen importantes desigualdades de género en las condiciones de empleo, trabajo y en los problemas de salud relacionados con el trabajo, que se ven influenciadas por la clase social y el sector de actividad, y que sería necesario tener en consideración en las políticas públicas de salud laboral.

Fatores de risco em saúde mental : contributos para o bem-estar biopsicossocial dos profissionais da saúde

CONTEXTO: A nossa investigação estuda o stress no trabalho e a sua relação com a saúde mental. Descrevemos fatores específicos e de risco psicossocial no trabalho, particularmente no trabalho dos enfermeiros, e as suas implicações para a saúde mental e para o bem-estar biopsicossocial, tais como: Tipo de trabalho; Conteúdo do trabalho; Desempenho de papel; Relações interpessoais e grupais; Desenvolvimento da carreira; Novas tecnologias e Aspetos organizacionais. OBJETIVO(S): O objetivo fundamental foi estudar a influência de algumas variáveis pessoais e situacionais de risco biopsicossocial na saúde mental e no bem-estar dos profissionais de saúde, em contexto hospitalar METODOLOGIA: Trata-se de um estudo quantitativo, transversal e descritivo, do tipo correlacional. A recolha de informação obedeceu a um protocolo constituído por dados pessoais e as escalas: Satisfação geral do trabalho, Questionário geral de saúde, Questionário de saúde, Escala de fadiga crónica, Escala de ansiedade cognitiva-somática, Inventário de personalidade de Eysenck, Inventário clínico de autoconceito, Inventário de resolução de problemas, Questionário de vulnerabilidade ao stress e Questionário de stress ao trabalho. A amostra foi não probabilística intencional, constituída por 570 enfermeiros, a laborarem por turnos e em regime normal, no contexto hospitalar, perfazendo, no final, 360 enfermeiros. RESULTADOS: Os principais resultados apontam o seguinte: Os enfermeiros manifestam algum descontentamento com o ambiente de trabalho; A globalidade da amostra demonstra índices de saúde baixos; Regra geral, todos os enfermeiros estão vulneráveis ao stress; Em relação ao stress produzido pelas circunstâncias organizacionais, a totalidade da amostra revela elevados índices de stress e o seu bem-estar biopsicossocial, manifestamente afetado. CONCLUSÕES: Destes resultados fomos levados a concluir que quanto maior for a fadiga crónica, o neuroticíssimo e a ansiedade cognitiva, maior será a tendência dos enfermeiros para diminuírem a autorresponsabilização e o medo. Esta relação pode tornar-se circular e levar a comportamentos desajustados como, por exemplo, indiferença, desinteresse, relações interpessoais conflituosas, entre outros aspetos. As consequências de tais comportamentos poderão traduzir-se em absentismo, erros de desempenho ou vontade de abandonar a instituição.

Opiniões sobre a visita de enfermagem em unidades de cirurgia: tradução, adaptação e validação de questionários

Enquadramento: Apesar da visita de enfermagem ou passagem de turno junto dos doentes garantir a continuidade dos cuidados de enfermagem, origina diversas questões éticas. Objetivos: Traduzir, adaptar e validar 2 questionários de colheita de dados sobre a visita de enfermagem em unidades cirúrgicas para a cultura portuguesa; identificar a opinião dos doentes e dos enfermeiros sobre a visita de enfermagem. Metodologia: Tradução, retroversão e adaptação dos questionários aplicados em 7 unidades cirúrgicas de um hospital central em Portugal de 22/08/2008 a 28/06/2009. A amostragem não probabilística acidental foi constituída por 137 enfermeiros e 96 doentes. Resultados: A visita de enfermagem promove a relação empática e de ajuda; a observação do doente e o planeamento de cuidados, no entanto é necessário clarificar o seu objetivo; incentivar à participação e ao envolvimento dos doentes; utilizar um discurso compreensível e garantir a privacidade da informação. Conclusão: Os questionários revelaram-se fidedignos e válidos na identificação das opiniões dos doentes e dos enfermeiros sobre a visita de enfermagem nas unidades de cirurgia em estudo.
