Úlcera de pressão em pacientes internados em um hospital universitário em Natal/RN: condições predisponentes e fatores de risco

The pressure ulcers (PU), also known as decubitus ulcers, are defined as injuries caused by the constant pressure exerted on a particular point of the body, causing impairment of blood supply with a decrease or interruption of tissue irrigation, causing occlusion of blood vessels and capillaries, ischemia and cell death. This is a descriptive study with longitudinal design, and panel type, with quantitative approach that aimed to examine the association between predisposing conditions (PC), intrinsic factors (IF) and extrinsic factors (EF) with the occurrence of PU, in hospitalized patients in the Intensive Care Unit (ICU), pain clinical, surgical clinical and neurology wards of a university hospital. The study population was composed of all patients who were restricted to bed during the period from December 2007 to February 2008. The study was approved by the Ethics Committee of HUOL / UFRN (No 135/07). The data-collection took place through a structured formulary of observation, data from medical records and physical examination of patients skins. The results were organized in SPSS 15.0 software, tabulated, categorized and analyzed by descriptive and inferential statistics. Of the 30 patients studied, 43.3% had been hospitalized in the pain clinical and surgical clinic wards, 20.0% in the ICU, 20.0% in the ICU / ward and 16.7% in neurology, being the length of hospitalization in those units of 7 to 18 days (63.3%) and from 19 to 30 days (36.7%), predominantly female and aged ≥ 60 years (60.0%). 19 PU were diagnosed in 43.3% of patients monitored, being 38.5% with one PU between 7 to 18 days and 46.2% with two or more between 19 to 30 days of hospitalization, showing significant relationship (ρ-value = 0029) between length of hospital stay and the number of PU. Was found an association of 35.7% of the PC (cardio-respiratory, hematological, metabolic and psychogenic), IF (age group, oedema, skin changes in humidity and change of body temperature) and EF (type of mattress and strength of body pressure) for all patients studied, statistically significant (ρ-value = 0001), between the average scores in patients with and without PU, with reason chance to 12.0 for the development of PU and there was moderate correlation ( r = 0618) in the presence of this association. Results show the influence of the multiplicity of factors and conditions on the occurrence of PU, which brings us to reflect on the assistance focused on prevention and reduction of these injuries which will encourage the reduction of hospitalization length, physical and psychological suffering, and the possibility of improving the clinical condition of the patient.

O sofrimento do paciente na UTI : escutando a sua experiência

In tertiary care, the Intensive Care Unit (ICU) is nowadays one of the most complex settings in providing care to critically ill patients and could make the difference in favor of life. Nevertheless, the stigma of death which pervades the imagination when the ICU is mentioned and the excessive importance placed on machines rather than on the human being end up by causing distress to some extent. As the purpose of this investigation is to understand the distress caused to a patient in an ICU, it has been grounded on the following question: What kind of distress does a patient go through during his/her experience in an ICU? This study has, therefore, an analytical and reflexive character embedded in a qualitative dimension of a phenomenological approach based on narratives. To this purpose, five patients were interviewed from November to December 2008. Out of the empirical material gathered from these narratives we were able to identify several factors that cause distress to ICU patients. Among them were: the certainty that they are critically ill and fear death, a closed room, too much lighting, a typical loneliness arising from being isolated from family members and dear ones, lack of communication with the professional staff, and noise; besides having to undergo therapeutic procedures. In summary, although the ICU is seen as a place of distress, in many aspects and in accord with this research, such distress can and should be relieved. On the other hand, being near to death leads them to a redefinition of life, said the patients.

O trabalho em saúde como espaço pedagógico: desafios e possibilidades

The ongoing transformations in brazilian society, arising from technical and organizational changes in the working world, are making, with much emphasis, heated debates resurge related to themes and issues that refer to the relationship between work, skills and education. Thus, this study is inserted in the link between education and work, pointing to the work as an educational principle according to Antonio Gramsci. This paper aims to discuss the interfaces between education and work in the everyday health care teams and learn about the activities developed by health teams related to the learning processes in and with the work to analyze the opportunities and challenges of transforming spaces of health work in an environment of lifelong learning. This is a descriptive, exploratory with a qualitative approach case study developed from semi-structured interviews with the health staff professionals of the Unidade de Terapia Intensiva da Casa de Saúde Dix-Sept Rosado in Mossoró / RN , who answered open questions about the relationship between education and work. The interviews were conducted during the month of January 2010, the same being recorded, transcribed and analyzed, culminating in the production of new knowledge on the subject. It is understood that work and education activities are eminently human, therefore only the human being works and educates. Given the statements of participants, it is noticed that all work processes in health are learning moments. This happens through new demands imposed by the everyday of the services, by interaction with a multidisciplinary team, participation in educational activities and individual study. It was noticed that the institution in this case does not promote study courses related to Intensive Care and that there are obstacles to the realization of educational activities on and with the work, such as: excessive workload, inability to release staff to participate in events, low pay, which leads the worker to have more than one employment, rejection of new knowledge by some workers and lack of physical infrastructure and incentives for the activities. The daily situations must be transformed in learning, selfanalyzing the problems of practice and valuing the work process itself in its intrinsic context. We conclude that dealing with the web of relationships between educational processes and production processes of health services, unraveling the intricacies of the world of work and education requirements in this sector are increasingly on the agenda of Sistema Único de Saúde workers and managers. The continuing consideration of this issue becomes an essential condition for the proper discharge of their responsibilities. We consider that bringing the education to everyday life is the result of recognition of the educational potential of the work situation

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

Atendimento Pré-hospitalar Móvel. Mapeando Riscos e Prevenindo Erros

The attention with safety of the patients is important in the quality of the nursing and health care. In the pre-hospital care, such care is essential on site with the purpose of avoiding possible consequences to the individual, ensuring a fast and appropriate care, with improvement of the morbidity and reduction of the mortality. This medical attention is equally associated with the significant risks of adverse events and serious mistakes, which can be reduced with the awareness of the professionals, organization and quality management. It is a descriptive, transversal research, of quantitative approach, with the objective of identifying the risks for the safety of the patient during the mobile pre-hospital care under the view of the nurses, in a city of the Brazilian Northeast. The sample was formed by 23 nurses. The inclusion criteria: to have at least two years of experience and accept to participate on the research. The data collection was done in two steps, first photo collection, through the adapted method of photographic analysis, and the second with the application of questionnaire, divide in two parts: socio-professional data and digital photo punctuation instrument of the patient s safety. The majority of the nurses had an average working time in the mobile pre-hospital care of six years and six months, in the age group of 38 to 53 years old (69,56%) and with Lato sensu specialization (73,91%), being (29,41%) emergency and (29,41%) in intensive care. The (74%) have the Advance Cardiac Life Support (ACLS) and (100%) have the Pre-Hospital Trauma Life Support (PHTLS); (91, 30%) know the thematic safety of the patient. On the pictures it was observed a bigger variability of the categories (risks) where 44% of variance emerged on the first picture of the research. The pictures 4 and 9 with the average below 5 were classified as very insecure, while pictures 7 and 3 with an average above 7, very secure. On the results of risks observed for the patient s safety in the mobile pre-hospital care five categories emerged: organization and packaging of the equipment and materials, routines and specificities in the mobile pre-hospital care, risks on the management of medications, for traumas and infections. Starting from the analysis of these risks, it was proposed ten steps for the safety in the mobile pre-hospital care: 1- Identify the patient; 2- Safety related to prevention of infection; 3- Safety in the management of medications; 4- Safety and standardization of the packaging of equipment and materials; 5- Attention to the specificities of the mobile pre-hospital care; 6- Incentive and value the participation of the patient and family; 7- Promote the communication with the central of regulation; 8- Prevention of traumas and falls; 9- Protect the skin from additional injuries; 10- Understand the benefit of all the equipment in the ambulance. The multiple risks and their emerged combinations on the research indicate a variety of actions to be developed and stimulated, like the use of steps for the patient s safety in the mobile pre-hospital care which contributes with the aid and management of risks, reduction of mistakes, disabilities and death

Arquitetura inteligente fuzzy para monitoramento de sinais vitais de pacientes: um estudo de caso em UTI

The area of the hospital automation has been the subject a lot of research, addressing relevant issues which can be automated, such as: management and control (electronic medical records, scheduling appointments, hospitalization, among others); communication (tracking patients, staff and materials), development of medical, hospital and laboratory equipment; monitoring (patients, staff and materials); and aid to medical diagnosis (according to each speciality). This thesis presents an architecture for a patient monitoring and alert systems. This architecture is based on intelligent systems techniques and is applied in hospital automation, specifically in the Intensive Care Unit (ICU) for the patient monitoring in hospital environment. The main goal of this architecture is to transform the multiparameter monitor data into useful information, through the knowledge of specialists and normal parameters of vital signs based on fuzzy logic that allows to extract information about the clinical condition of ICU patients and give a pre-diagnosis. Finally, alerts are dispatched to medical professionals in case any abnormality is found during monitoring. After the validation of the architecture, the fuzzy logic inferences were applied to the trainning and validation of an Artificial Neural Network for classification of the cases that were validated a priori with the fuzzy system

Monitoramento de fungos anemófilos e de leveduras em unidade hospitalar

OBJETIVO: Monitorar e caracterizar fungos anemófilos e leveduras de fontes bióticas e abióticas de uma unidade hospitalar. MÉTODOS: As coletas foram realizadas mensalmente e em dois períodos, do centro cirúrgico e unidades de terapia intensiva adulto e neonatal em hospital de Araraquara, Estado de São Paulo. Para coleta de fungos anemófilos foi utilizado amostrador tipo Andersen de simples estágio. A pesquisa de leveduras foi feita das mãos e de orofaringe de profissionais de saúde, bem como de superfícies de leitos e de maçanetas das áreas críticas. RESULTADOS: Foram recuperados do centro cirúrgico 32 gêneros de fungos anemófilos e 31 das unidades de terapia intensiva. Os gêneros mais freqüentemente isolados foram Cladophialophora spp., Fusarium spp., Penicillium spp., Chrysosporium spp. e Aspergillus spp. Durante o período de estudo, houve reforma e implantação de uma unidade dentro do hospital, que coincidiu com o aumento na contagem de colônias de Cladophialophora spp., Aspergillus spp. e Fusarium spp. Leveduras foram encontradas em 39,4% dos profissionais de saúde (16,7% das amostras dos espaços interdigitais, 12,1% do leito subungueal e 10,6% da orofaringe) e, em 44% das amostras do mobiliário, com predomínio do gênero Candida (C. albicans, C. guilliermondii, C. parapsilosis e C. lusitaniae) seguido por Trichosporon spp. CONCLUSÕES: Observou-se número relativamente elevado de fungos anemófilos (potencialmente patogênicos) em áreas especiais e níveis expressivos de leveduras em fontes bióticas e abióticas. O monitoramento microbiológico ambiental deve ser realizado, principalmente em salas especiais com pacientes imunocomprometidos, sujeitos à exposição de patógenos do meio ambiente, assim como, advindos de profissionais de saúde.

Detection of mixed microbial biofilms on central venous catheters removed from Intensive care Unit Patients

Cateteres venosos centrais inseridos em pacientes internados em unidade de terapia intensiva foram avaliados por métodos microbiológicos (cultura semi-quantitativa) e microscopia eletrônica de varredura a fim de detectar adesão microbiana e correlacionar com a cultura de sangue. Durante o período de estudo, foram avaliados 59 pacientes com cateter venoso central. A idade dos pacientes, sexo, sítio de inserção e tempo de permanência do cateter foram anotados. O cateter era de poliuretano não tunelizado e de único lúmen. O sangue para cultura foi coletado no momento da remoção do cateter. de 63 pontas de cateteres, 30 (47,6%) foram colonizadas e a infecção encontrada em 5 (23,8%) cateteres. A infecção foi mais prevalente em 26 pacientes (41,3%) com cateteres inseridos em veia subclávia do que nos 3 (3,2%) inseridos em veia jugular. A infecção foi observada com mais freqüência em cateteres com tempo de permanência maior do que sete dias. Os microrganismos isolados incluíram 32 estafilococos coagulase-negativa (29,7%), 61 bactérias Gram-negativas (52,9%), 9 estafilcocos coagulase-positiva (8,3%) e 3 leveduras (2,7%). Como agentes causais de infecções em unidade de terapia intensiva foram isolados E. aerogenes, P. aeruginosa, A. baumannii. Os antimicrobianos com maior atividade in vitro contra as bactérias Gram-negativas foram o imipenem e contra as Gram-positivas vancomicina, cefepime, penicilina, rifampicina e tetraciclina. As análises por microscopia eletrônica de varredura revelaram biofilmes sobre a superfície de todos os cateteres examinados.

Anestesia para separação de gêmeos isquiópagos no período neonatal: relato de caso

JUSTIFICATIVA E OBJETIVOS: A separação de gêmeos unidos causa grande interesse devido à complexidade da anestesia e cirurgia, à raridade da patologia e às poucas chances de sobrevida. O objetivo desta descrição é o de contribuir para a literatura existente, relatando os desafios encontrados por nossa equipe no atendimento à cirurgia-anestesia de separação de gêmeos isquiópagos. RELATO do CASO: Pacientes gêmeos, nascidos a termo, de parto cesariano, pesando juntos 5.100 g, classificados como isquiópagus tetrapus. Duas equipes anestésico-cirúrgicas estavam presentes, sendo o procedimento anestésico esquematizado com aparelho de anestesia, cardioscópio, capnógrafo, oxímetro de pulso, termômetro elétrico, estetoscópio esofágico, todos em dobro. Realizou-se indução anestésica com halotano e fentanil, com os gêmeos em posição lateral e com rotação da cabeça em 45º para facilitar a intubação traqueal. Os recém-nascidos foram mantidos em ventilação controlada manualmente, utilizando o sistema de Rees-Baraka. A anestesia foi mantida com halotano, oxigênio e fentanil. Durante o per-operatório, foram encontrados órgãos abdominais duplos, com exceção do cólon, que era único. As bexigas e os ísquios estavam ligados. Ao final da cirurgia as duas crianças apresentavam-se com sinais vitais estáveis. Os gêmeos permaneceram na Unidade de Terapia Intensiva (UTI) Neonatal por quatro semanas e receberam alta em bom estado geral. CONCLUSÕES: Ressalta-se a importância do entrosamento da equipe, do estudo retrospectivo multidisciplinar, da monitorização adequada e acurada observação clínica; todos esses fatores contribuíram para a boa evolução e alta dos gêmeos.

Avaliação do desempenho diagnóstico e do valor de corte para o índice de respiração rápida e superficial na predição do insucesso da extubação

OBJETIVO: Avaliar o desempenho diagnóstico do índice de respiração rápida e superficial (IRRS) na predição do insucesso da extubação de pacientes adultos em terapia intensiva e verificar a adequação do valor de corte clássico para esse índice. MÉTODOS: Estudo prospectivo realizado na unidade de terapia intensiva de adultos do Hospital das Clínicas da Faculdade de Medicina de Botucatu, através da avaliação do IRRS em 73 pacientes consecutivos considerados clinicamente prontos para extubação. RESULTADOS: O IRRS com valor de corte clássico (105 ciclos/min/L) apresentou sensibilidade de 20% e especificidade de 95% (soma = 115%). A análise da curva receiver operator characteristic (ROC) demonstrou melhor valor de corte (76,5 ciclos/min/L), o qual forneceu sensibilidade de 66% e especificidade de 74% (soma = 140%), e a área sob a curva ROC para o IRRS foi de 0,78. CONCLUSÕES: O valor de corte clássico do IRRS se mostrou inadequado nesta casuística, prevendo apenas 20% dos pacientes com falha na extubação. A obtenção do novo valor de corte permitiu um acréscimo substancial de sensibilidade, com aceitável redução da especificidade. O valor da área sob a curva ROC indicou satisfatório poder discriminativo do índice, justificando a validação de sua aplicação.

Comparação entre dois testes de rastreamento do diabetes gestacional e o resultado perinatal

OBJETIVO: comparar dois testes de rastreamento para diabetes e seus resultados com o resultado da gestação. MÉTODOS: no total, 279 pacientes foram submetidas a dois testes de rastreamento do diabetes gestacional - associação glicemia de jejum e fatores de risco (GJ + FR) e o teste de tolerância à glicose simplificado (TTG50g). O rastreamento pela associação GJ + FR caracterizou-se pela dosagem da glicemia de jejum e anamnese para identificação dos fatores de risco na primeira consulta de pré-natal. O TTG50g foi realizado entre a 24ª e a 28ª semana de gestação e caracterizou-se pela dosagem das glicemias plasmáticas em jejum e uma hora após a sobrecarga oral com 50 g de glicose. Os resultados, positivo e negativo, foram relacionados ao resultado da gestação. Foram consideradas variáveis dependentes: via de parto, idade gestacional, peso e índice ponderal ao nascimento, índices de Apgar <7 no 1º e 5º minutos, necessidade de Unidade de Terapia Intensiva (UTI), tempo de permanência hospitalar e óbito neonatal. Empregou-se o teste t de Student, admitindo-se 5% como limite de significância para calcular a diferença de proporção de das médias. RESULTADOS: apenas dois resultados perinatais estudados foram diferenciados pelos testes. O TTG50g alterado esteve associado à maior proporção de cesárea (58,7 versus 34,3%) e a associação GJ + FR positiva, maior taxa de prematuridade (15,4 versus 5,4%). As demais variáveis não foram diferentes nas pacientes com testes de rastreamento positivo e negativo. CONCLUSÕES: Apesar da relação entre a prematuridade e associação GJ + FR positiva e aumento de cesárea e TTG50g alterado, seria falha crítica aceitá-los como definitivos. Entre outras explicações, múltiplos fatores intercorrentes e as características próprias dos testes de rastreamento devem ser consideradas.

Óxido nítrico inalatório para crianças com síndrome do desconforto respiratório agudo

JUSTIFICATIVA E OBJETIVOS: O objetivo desse estudo foi rever a literatura sobre a utilização de óxido nítrico inalatório em crianças com síndrome do desconforto respiratório agudo. CONTEÚDO: Revisão bibliográfica e seleção de publicações mais relevantes sobre óxido nítrico inalatório, utilizando a base de dados MedLine e Cochrane de Revisões Sistemáticas. A revisão incluiu descrição de aspectos da definição, fisiopatologia e tratamento ventilatório da síndrome do desconforto respiratório agudo, assim como o metabolismo, efeitos biológicos e aplicação clínica do óxido nítrico inalatório, comentando dose, administração e retirada do gás, precações, efeitos adversos e contra-indicações. CONCLUSÕES: O óxido nítrico, vasodilatador pulmonar seletivo, tem efeitos benéficos sobre as trocas gasosas e ventilação em crianças com hipóxia grave. É seguro quando administrado em ambiente de tratamento intensivo sob rigorosa monitorização. Estudos aleatórios e controlados devem enfocar a administração precoce do gás na síndrome do desconforto respiratório agudo, quando essa é potencialmente reversível.
