We observed a tendency to invest in therapeutical and in studies about the production of sophisticated new bandages. Few, however, are the investments in research on preventive measures in order to prevent or at least slow down the development of lesions. In this sense, the study aimed to analyze the correlation between nursing care and the risk of developing UP measured by the Braden scale in ICU patients. This is a descriptive study of longitudinal quantitative approach. The project obtained a favourable opinion from the Ethics Committee of HUOL (no 486/10). Data collection was carried out in the Hospital of Unimed in Natal during six months in 2011. The sample was of 32 patients hospitalized in ICU for over four days. The results were processed in SPSS 15.0 for descriptive statistics and inferential statistics. We identified that, only 9.4% of our sample developed UP, being predominantly male, elderly people aged above 60 years, Caucasian, with diagnostic hypothesis at the time of hospitalization of sepsis, were clinical patients, who presented hemodynamic instability, using orotracheal tube (TOT), enteral probe (SNE), vesical probe delay (SVD) and had values of albumin and hemoglobin levels below normal. In addition, these patients had a longer hospital stay, longer usage of TOT, SNE, SVD, increased use of sedation and drain than those who did not develop UP and were all at risk for developing these injuries second Braden scores. 66.7% of the lesions developed were located in the sacral region, limiting the degree I and all patients that developed were considered serious, 100.0% of them have evolved since the death. Small were the differences between the averages of Braden scores between patients with and without UP, 11,9+2,4 against 12,4+2,6 with p = 0.627. The clinical aspects of the patients in the study were instrumental in the development of UP, once, these findings were statistically significant through the Mann-Whitney test, and appropriateness of nursing conduct was decisive for the prevention of pressure ulcers in critical patients, since many were those classified as at risk (28) and few who have developed lesions (03) / A problem?tica frente ? incid?ncia de ?lcera de press?o (UP) no ambiente hospitalar, especialmente na Unidade de Terapia Intensiva (UTI), embora seja evento antigo e frequente, se observado em nossa pr?tica profissional, ? fato pouco notificado e com escassos estudos. Observamos uma tend?ncia em investir em condutas terap?uticas e em estudos para produ??o de novas coberturas sofisticadas. Poucos, por?m, s?o os investimentos em pesquisas sobre medidas preventivas com intuito de evitar ou pelo menos retardar o desenvolvimento das les?es. Nesse sentido, o estudo teve como objetivo analisar a correla??o entre a assist?ncia de enfermagem e o risco de desenvolvimento de UP medido pela escala de Braden em pacientes de UTI. Trata-se de um estudo descritivo longitudinal de abordagem quantitativa. O projeto obteve parecer favor?vel do Comit? de ?tica do HUOL (n.486/10). A coleta de dados realizou-se no Hospital da Unimed Natal, num per?odo de seis meses, em 2011. A amostra foi de 32 pacientes internados na UTI por mais de quatro dias. Os resultados foram processados no programa SPSS 15.0 por estat?stica descritiva e inferencial. Identificamos queapenas 9,4% de nossa amostra desenvolveram UP, sendo predominantemente do sexo masculino, idosos com faixa et?ria acima de 60 anos, de ra?a branca, com hip?tese diagn?stica no momento da interna??o de sepse; eram pacientes cl?nicos, que apresentaram instabilidade hemodin?mica, utilizando tubo orotraqueal (TOT), sonda enteral (SNE), sonda vesical de demora (SVD) e tinham valores de albumina e hemoglobina abaixo do normal. Al?m disso, estes pacientes apresentaram um maior tempo de internamento, maior tempo de uso de TOT, de SNE, de SVD, maior tempo de uso de seda??o e de dreno do que aqueles que n?o desenvolveram UP, e eram todos de risco para o desenvolvimento destas les?es segundo escores de Braden. Das les?es desenvolvidas, 66,7% localizavam-se na regi?o sacral, limitando-se a grau I, e todos os pacientes que as desenvolveram eram considerados graves, visto que 100,0% deles evolu?ram a ?bito. Pequenas foram as diferen?as entre as m?dias dos escores de Braden entre os pacientes com UP e os sem UP, 11,9+2,4 contra 12,4+2,6 com p=0,627. Os aspectos cl?nicos dos pacientes do estudo foram determinantes para o desenvolvimento de UP, uma vez que esses achados foram significantes estatisticamente atrav?s do teste de Mann-Whitney, e a adequa??o das condutas de enfermagem foi decisiva para a preven??o das ?lceras por press?o em pacientes cr?ticos, uma vez que muitos eram aqueles classificados como de risco (28) e poucos os que desenvolveram les?es (3)

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 / Identificar a incid?ncia de UP em pacientes internados nas UTIs, segundo sexo, faixa et?ria, tempo de interna??o, hip?tese diagn?stica e localiza??o de ?lcera de press?o; identificar a incid?ncia de ?lcera de press?o (UP) nas Unidades de Terapias Intensivas (UTIs); identificar as condi??es predisponentes, fatores intr?nsecos e extr?nsecos presentes nos pacientes internados nas UTIs e verificar a exist?ncia de associa??o entre as condi??es predisponentes e os fatores intr?nsecos e extr?nsecos na ocorr?ncia de UP. M?todos: Trata-se de um estudo descritivo, com delineamento longitudinal do tipo painel, com abordagem quantitativa, realizado em duas UTIs de um hospital privado localizado em Natal/RN, com 40 pacientes internados nessas unidades. A coleta dos dados foi realizada nos tr?s turnos por meio de um formul?rio estruturado de observa??o e exame f?sico da pele dos pacientes buscando identificar a presen?a de UP. Resultados: A maior ocorr?ncia de UP foi em indiv?duos do sexo masculino (70%) em rela??o ao feminino (30%), sendo esta diferen?a, estatisticamente significante (p= 0,0267), com sexo masculino apresentando 4,3 vezes mais chance de desenvolver UP do que o feminino; a faixa et?ria predominante foi a partir de 60 anos (85%), 60,0% apresentaram de 1 a 2 UPs ap?s 7 (sete) dias de perman?ncia nas UTIs, a hip?tese diagn?stica predominante nos pacientes com UP, foram as doen?as respirat?rias (42,3%) e as localiza??es mais freq?entes de UP foram ? regi?o sacral (40,0%) e calc?neos (36,0%). Foram diagnosticadas 25 UPs em est?gio I em 50,0% dos pacientes acompanhados, com incid?ncia geral de 50% nas duas UTIs. Das 88 vari?veis pesquisadas, 75 foram identificadas nos pacientes do estudo, sendo que as condi??es predominantes (anemia, hipotens?o, leucocitose, outra doen?as (HAS, ICO, PNM) e ansiol?tico), os fatores intr?nsecos (a for?a e/ou massa muscular diminu?da, edema discreto, coordena??o motora totalmente prejudicada e inabilidade total para movimenta??o no leito) e os fatores extr?nsecos (tipo de colch?o inadequado, posicionamento em um mesmo dec?bito por >2 horas, for?a de cisalhamento/fric??o, roupas de cama com dobras deixando marcas no corpo, for?a de press?o) predominaram nos pacientes com UP. As vari?veis como sexo masculino (p=0,0267, RC=4,3), seda??o (p=0,0015, RC=9,3), for?a de cisalhamento/fric??o (p=0,0393, RC=3,3), for?a de press?o (p=0,0006, RC=4,1), agita??o psicomotora (p=0,0375, RC=5,8) e leucocitose (p=0,0285, RC=5,0) apresentaram diferen?a estat?stica significante quando analisadas isoladamente. Verificamos uma associa??o de 17,3%, estatisticamente significante (p=0,0384), entre as condi??es predisponentes (anemia, leucocitose e hipotens?o), os fatores intr?nsecos (idade maior ou igual a 60 anos, sensibilidade dolorosa diminu?da/ausente e pele lisa, fina ou delicada) e os fatores extr?nsecos (colch?o inadequado, for?as de press?o, for?a de cisalhamento/fric??o, posicionamento em um mesmo dec?bito por mais de 2 horas, eleva??o de 30 a 45 graus e condi??es de roupas de cama inadequadas), com uma raz?o de chance de 4,6 vezes o risco de ocorr?ncia de UP nos pacientes que apresentaram a referida associa??o. Conclus?o: A incid?ncia de UP detectada nos pacientes internados nas UTIs foi elevada e evidenciamos a exist?ncia de associa??o entre as condi??es predisponentes, os fatores intr?nsecos e extr?nsecos na ocorr?ncia de UPs nos pacientes internados nas UTIs, portanto aceitamos a hip?tese alternativa proposta no estudo

O estudo permitiu explorar e conhecer os termos utilizados pelos enfermeiros na assist?ncia prestada ao paciente com les?o por press?o, possibilitando o desenvolvimento futuro dos enunciados de diagn?sticos / resultados e interven??es de enfermagem e tamb?m a unifica??o da linguagem profissional do enfermeiro. / Pressure injury is the result of prolonged pressure on an area of the patient's body by decreasing blood circulation, minimizing the distribution of blood, nutrients, and oxygen in this area, triggering destruction and tissue death, as the soft tissue is compressed between a bone prominence and a hard surface for an extended period of time. The terms bank of the special nursing language identifies concepts that contribute to the construction of nursing diagnoses, results and interventions. The use of this bank aimed at patients with pressure lesions allows the development of a pyramidal identification of an own vocabulary directed to nursing care. The aim of the study was to construct a bank of terms of the special nursing language for patients with pressure injury, using the International Classification for Nursing Practice version 2017. This is a terminological study in a private hospital in the northeast capital of the Brazil developed in six steps: 1) Identification and collection of terms relevant to the practice of Nursing related to pressure injury; 2) Extraction of the terms of the medical records and elimination of repetitions; 3) Standardization of terms; 4) Cross-mapping between extracted terms and the terms in CIPE? version 2017; 5) Refinement of terms; 6) Validation of the terms bank statements. Approval was obtained from the Research Ethics Committee of the Federal University of Rio Grande do Norte, under opinion no. 2.356.736 and Certificate of Presentation for Ethical Appreciation n? 76777017.20000.5537. It was identified 391 terms that were submitted to the process of cross-mapping and validation of specialists that resulted in 370 terms, being 225 constant terms and 145 terms not included in the International Classification for Nursing Practice, version 2017. The study allowed to explore and to know the terms used by nurses in the care provided to the patient with pressure injury, allowing the development of statements of diagnosis/results and nursing interventions and also the unification of nurses' professional language.

Diante da gravidade, complexidade e grau de depend?ncia dos pacientes cr?ticos, surge a necessidade da enfermagem avaliar a presen?a desse diagn?stico para atuar na preven??o dos fatores de risco e na manuten??o da qualidade nos servi?os ofertados. Tratou-se de um estudo metodol?gico, desenvolvido em tr?s etapas: an?lise de conceito, an?lise do conte?do por especialistas e valida??o cl?nica. A primeira etapa foi baseada no modelo de Walker e Avant e operacionalizada atrav?s de revis?o da literatura, que aconteceu nos meses de fevereiro e mar?o de 2015. Utilizaram-se as bases de dados: Scopus, Literatura Latino-Americana e do Caribe em Ci?ncias da Sa?de, Cumulative Index to Nursing and Allied Health Literature, National Library of Medicine and Nattional Institutes of Health e Web of Science, e os descritores: ?lcera por press?o, fatores de risco e unidades de terapia intensiva e suas respectivas sinon?mias em ingl?s. Obteve-se uma amostra de 22 artigos. Ap?s a an?lise do conceito, identificaram-se 42 antecedentes e os seguintes atributos essenciais: Press?o; Press?o em combina??o com cisalhamento; e Isquemia tecidual. Na segunda etapa, foram solicitadas as opini?es dos especialistas com rela??o ? an?lise de conceito e de conte?do, por meio de grupo focal, composto por sete enfermeiras, em quatro encontros, durante os meses de maio a julho de 2015. Ap?s a discuss?o no grupo focal, resultou-se um total de 29 antecedentes e na seguinte defini??o conceitual para o diagn?stico estudado: Vulnerabilidade de rompimento da integridade da pele como resultado da isquemia tecidual ocasionada por press?o ou press?o em combina??o com cisalhamento. Na terceira etapa, foi realizado um estudo de caso-controle, com intuito de avaliar, na pr?tica cl?nica, a precis?o dos fatores de risco do diagn?stico de enfermagem identificados e validados nas etapas anteriores. Esta etapa ocorreu na unidade de terapia intensiva do Hospital Universit?rio Onofre Lopes, atrav?s de um formul?rio. A amostra consistiu de 180 participantes, sendo 90 no grupo caso e 90 no grupo controle. O projeto de pesquisa foi submetido e aprovado pelo Comit? de ?tica em Pesquisa do referido hospital, sob n?mero de protocolo 848.997 e Certificado de Apresenta??o para Aprecia??o ?tica 36883714.5.0000.5292. Os resultados mostram que, atrav?s da aplica??o do modelo de regress?o log?stica hier?rquica, um conjunto de cinco fatores de risco e um aspecto cl?nico deve ser visto como um forte indicativo do aumento do risco para ?lcera por press?o. Os fatores de risco foram: Hist?ria de ?lcera por press?o, Tempo prolongado de perman?ncia na UTI; Fric??o, Desidrata??o e Temperatura elevada da pele em torno de 1 a 2 ?C. E o aspecto cl?nico foi: Tratamento das comorbidades. Conclui-se que o diagn?stico de enfermagem Risco de ?lcera por press?o p?de ser validado em seus aspectos de conceito, de conte?do e cl?nicos e que existe um conjunto de vari?veis que aumentam a chance da ocorr?ncia do diagn?stico de enfermagem Risco de ?lcera por press?o em pacientes internados em unidade de terapia intensiva. Assim, acredita-se que o estudo contribuiu para o aperfei?oamento da linguagem diagn?stica, com vistas a ado??o de medidas preventivas, aplica??o de interven??es mais eficazes, alcance de resultados positivos e melhoria da qualidade do cuidado prestado pelo enfermeiro. / The objective of this study was to validate the nursing diagnosis ?Pressure ulcer risk? in patients admitted to the intensive care unit. Faced with the severity, complexity and degree of dependence of the critical patients, nursing needs to assess the presence of this diagnosis to act in the prevention of risk factors and maintenance of quality in the services offered. This was a methodological study, conducted in three steps: concept analysis, content analysis by experts and clinical validation. The first step was based on the model of Walker and Avant and performed through literature review, which occurred in the months of February and March 2015. We used the databases: Scopus, Latin American and Caribbean Health Sciences Literature, Cumulative Index to Nursing and Allied Health Literature, National Library of Medicine and National Institutes of Health, and Web of Science, and the descriptors: pressure ulcer, risk factors and intensive care units, and their respective synonyms in the English language. We obtained a sample of 22 papers. After completing the concept and content analysis, we identified 42 backgrounds and the following essential attributes: Pressure; Pressure combined with shearing; and Tissue ischemia. In the second step, we asked the experts to give opinions about the concept analysis, by means of a focus group, composed of seven nurses, in four meetings, which were held from May to July 2015. After finishing the discussion in the focus group, we had a total of 29 backgrounds, besides the following conceptual definition for the diagnosis under study: Vulnerability of rupture of the skin integrity as a result of the tissue ischemia provoked by pressure or pressure combined with shearing. In the third step, we conducted a case-control study with the aim of assessing, in clinical practice, the accuracy of the risk factors of the nursing diagnosis identified and validated in the preceding steps. This step took place in the intensive care unit of the Onofre Lopes University Hospital, through a form. The sample was composed of 180 participants, with 90 in the case group and 90 in the control group. The research project was submitted and approved by the Research Ethics Committee of the aforementioned hospital, under Protocol number 848.997 and Presentation Certificate for Ethics Assessment number 36883714.5.0000.5292. The results show that, through the application of the hierarchical logistic regression model, a set of five risk factors and one clinical aspect must be regarded as a strong indicator of the increased risk for pressure ulcer. The risk factors were: History of pressure ulcer; Extended period of stay in the ICU; Friction, Dehydration and High skin temperature around 1 to 2 ? C. As for the clinical aspect, it was: Treatment of comorbidities. We conclude that the nursing diagnosis of pressure ulcer risk could be validated in aspects of concept, content and clinical and that there is a set of variables that increase the chance of occurrence of the nursing diagnosis ?Pressure ulcer risk? in patients admitted to the intensive care unit. Accordingly, we believe that this study has contributed to the improvement of the diagnostic parlance, with regard to adopting preventive measures, applying more effective interventions, achieving positive results and improving the quality of the health care provided by the nursing professional.

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. / As ?lceras de press?o (UP), denominadas tamb?m ?lcera de dec?bito, s?o definidas como les?es causadas pela constante press?o exercida sobre um determinado ponto do corpo, ocasionando comprometimento do aporte sangu?neo com diminui??o ou interrup??o da irriga??o tissular, ocasionando oclus?o de vasos e capilares, isquemia e morte celular. Trata-se de um estudo descritivo com delineamento longitudinal, tipo painel, com abordagem quantitativa que objetivou analisar a associa??o existente entre condi??es predisponentes (CP), fatores intr?nsecos (FI) e fatores extr?nsecos (FE) com a ocorr?ncia de UP, em pacientes internados em Unidade de Terapia Intensiva (UTI), enfermarias de cl?nicas m?dica, cir?rgica e neurologia de um hospital universit?rio. A popula??o do estudo foi composta por todos os pacientes que estiveram acamados durante o per?odo de dezembro de 2007 a fevereiro de 2008. O estudo foi aprovado pelo Comit? de ?tica do HUOL/UFRN (no 135/07). A coleta de dados realizou-se por meio de um formul?rio estruturado de observa??o, dados dos prontu?rios e exame f?sico da pele dos pacientes. Os resultados foram organizados no programa SPSS 15.0, tabulados, categorizados e analisados por meio de estat?stica descritiva e inferencial. Dos 30 pacientes pesquisados, 43,3% encontravam-se internados na enfermaria de cl?nica m?dica e cl?nica cir?rgica, 20,0% na UTI, 20,0% na UTI/enfermaria e 16,7% na neurologia, sendo o tempo de interna??o nessas unidades de 7 a 18 dias (63,3%) e de 19 a 30 dias (36,7%), com predomin?ncia do sexo feminino e faixa et?ria ≥ 60 anos (60,0%). Foram diagnosticadas 19 UP em 43,3% dos pacientes acompanhados, 38,5% com uma UP entre 7 a 18 dias e 46,2% com duas ou mais entre 19 a 30 dias de interna??o, mostrando rela??o significativa (ρ-valor = 0,029) entre tempo de interna??o e o n?mero de UP. Verificou-se associa??o de 35,7% das CP (cardio-respirat?rias, hematol?gicas, metab?licas e psicog?nicas), FI (faixa et?ria, edema, altera??o na umidade da pele e altera??o da temperatura corporal) e FE (tipo de colch?o e for?a de press?o do corpo) no conjunto dos pacientes pesquisados, estatisticamente significante (ρ-valor = 0,001), entre as m?dias dos escores nos pacientes com e sem UP, com raz?o de chance de 12,0 de desenvolvimento de UP e exist?ncia de moderada correla??o (r = 0,618) na presen?a dessa associa??o. Os resultados denotam a influ?ncia da multiplicidade de fatores e condi??es na ocorr?ncia de UP, o que nos remete a refletir acerca da assist?ncia voltada para preven??o e diminui??o dessas les?es o que ir? favorecer a redu??o do tempo de internamento, sofrimento f?sico e psicol?gico, bem como a possibilidade de melhora do estado cl?nico do paciente.
