Qualidade de vida de pessoas com úlcera venosa: associação dos aspectos sociodemográficos, de saúde, assistência e clínicos da lesão

Venous ulcer (VU) is a lower limbs injury resulting from inadequate return of venous blood in feet or legs. Although it is not a deadly disease, it causes chronic wounds, which seriously undermine patients´ quality of life (QOL) and sometimes leads to drastic family, social, economic and psychological changes. In this sense, there are several aspects that may influence the venous ulcers patients´ QOL. The study´s objective aimed on the association of socio-demographic and health, health care and clinical injury on UV patients‟ QOL. Analytical studies, which consider the complexity of factors involved in changes in UV patients‟ QOL has a cross-sectional and quantitative approach. The HUOL Ethics Committee approved this project (n.279/09). The collection of data lasted a period of 3 months in 2010 and it took place at the clinic of Angiology at Hospital Universitário Onofre Lopes (HUOL). The data sample consisted of 60 patients treated by UV angiologists in the HUOL Surgical Clinic. The results were analyzed with SPSS 15.0 by descriptive and inferential statistics. The study was based on UV patients that were predominantly female, average age of 61.4 years, that had low education level and low family income, with occupations requiring long periods of standing or sitting, but mostly retired, unemployed or laid off due to the disease and/or due to chronic diseases associated with the UV. The study took also into consideration patients that used inappropriate products, that were improperly treated by a professional caregiver, that lacked of adequate guidance and compression therapy, that performed no lifting of the lower limbs and regular exercise, that the time of injury were greater than or equal to six months, that were missing specific laboratory tests. The study‟s reference were on recurrent lesions, medium to large lesions area, bed of the lesion (injuries) with fibrin and/or necrosis, with amount of exudate with medium to large, odorless and no signs of infection, with tissue loss between 1st and 2nd degree, without collecting swab or biopsy and with pain. In general, QOL of researched individuals were considered low, the maximum score was 69 points, which the areas that were mostly influenced were the total scores of QOL functional capacity (0.021), emotional (0.000) and social functioning (0.080). Of the 60 individuals, 53.3% had scores between 40 and 69 points in SF-36, and they had the best scores in sociodemographic and health variables (ρ = 0.049). In respect to the assistance and injury characteristics, patients who scored between 40 and 69 points in SF-36 had better scores on these characteristics. By combining the socio-demographic variables, health, and handling characteristics of the injury, we observed a significant difference (ρ = 0.032) when linking them with the QOL total scores. When analyzing separately the domains of the SF-36 scores on the quality of life, we find that the areas that showed statistical significance were functional ability (ρ = 0.035), appearance (ρ = 0.019), emotional (ρ = 0.000), and mental health (ρ = 0.050). Among the socio-demographic characteristics studied, gender and marital status contributed more to the reduction of QOL and among the variables of assistance and the injury, orientation, reference and area of UV contributed the most. By analyzing these five variables all together in accordance with the overall score obtained in the quality of life, we found a significant correlation (ρ = 0.002); with 6.23 times more chances of patients have better QOL in the presence of these five positive factors. By conducting the Mann Whitney U test between all the five demographic variables, health, and clinical care, we found that this combination also proved to be significant (ρ = 0.006). Therefore, patients with these five variables positive tend to have a better QOL. Based on these results, we reject the null hypothesis (H0) and accept the alternative hypothesis (H1) proposed in this study because we noted that the QOL of patients with UV is associated with sociodemographic and health, health care and clinical aspects of the injury

Validação de protocolo de assistência para pessoas com úlcera venosa na atenção primária

People with venous ulcers constitute as an important public health problem, its treatment is onerous and require assistance provided by trained professionals, systematized through protocols, however what lies in the assistance is that the management of this group of people differs from that preconized in the scientific literature, interfering with wound healing and quality of life of affected. In this sense, the construction of a assistance protocol specific to people with venous ulcers (VU) can help professionals of the Family Health Strategy both in patient assessment as and in establishment of quality assistance. Thus, this study aimed to analyse the validity of a multiprofessional assistance protocol for people with venous ulcers in primary care by health professionals using Delphi technique. This is a quantitative study, the methodological type conducted in two steps: first step related to integrative literature review to subsidize the development of the protocol, then these aspects were organized and proposed to the judges of the study through the Delphi technique. The study was initiated after approval by the Research Ethics Committee. The first step was performed between August and September 2012, in the virtual library of health, in the page of the Coordination of Improvement of Higher Education Personnel, of Municipal Health Secretariat and international guidelines of associations and in the subsequent step carried out between September 2012 to January 2013, was performed search by Lattes platform of the National Council of Technological and Scientific Development, in order to identify health professionals in Brazil who act as judges of the instrument and then, via online, the form was submitted to them.The sample for the second step was 51 judges in the first round and 35 for the second round Delphi. The analysis was done by adopting Kappa index ≥ 0.81 and Content Validity Index (CVI)> 0.80. In the first submission for the judges, items that did not reach Kappa and CVI established were: request / realization / test results, demographic data, medical history, risk factors, verification of pain / vital signs / pulse / infection signs / lesion location/ edema and pain treatment. After removal of items which have not obtained Kappa or CVI index established, it was found achieving optimal levels of these index for the categories. In the next step was the ressubmissão of protocol to judges through the Delphi technique in it was found that, of the 15 categories of the protocol, 12 presented higher scores in Delphi 2 phase and the other three categories remained the same Kappa and IVC of the previous phase. As for the average of evaluation requirements of the protocol was found that the scores assigned by the judges were higher in the second phase in nine of the 10 items, remaining the same in only one of the items indicating validity of the instrument before the consensus of the judges. Thus, we accepted the alternative hypothesis in this study, as they were obtained in the second Delphi phase the validity index greater than or equal to the Delphi 1 phase. The formulation of this assistance protocol valid and reproducible will enable a reorganization and redesign of assistance, with standardization of actions and continuity of care for persons with venous ulcers in primary health care

Qualidade da assistência e o conhecimento sobre o direito à saúde das pessoas com úlcera venosa crônica

The study aimed to identify the quality of care and knowledge of health rights of people with chronic venous ulcers (VU) in Brasilian National Health Care System (SUS). It is a cross-sectional study, with quantitative approach, performed at the University Hospital Onofre Lopes (HUOL). The study was approved by the Ethics Committee of HUOL (CAAE nº 0148.0.051.000-10). The sample by accessibility was composed for 30 people with VU treated at the outpatient surgical clinic of HUOL. For data collection we used a structured questionnaire composed of two parts: sociodemographic characteristics and of health, of care and the clinical course of VU; and knowledge of people with VU about the rights of health. The results were processed using SPSS 15.0 and analyzed by descriptive statistics. Given the characterizations sociodemographic and health presented, we identified a clientele of users with VU predominantly female (76,7%), aged from 60 years (66,7%), married/ stable union (60,0%), low education level (83,3%), family income lower than a minimum wage (73,3%), unemployeds and with chronic diseases (53,3%), sleep greater than or equal to 6 hours (76,7%) and were not alcoholics or smokers (93,3%). In relation to clinical conditions, were shown the presence of one or more relapses of VU (73,3%), predominance of granulation tissue/epithelialization in the bed of VU (60,0%), exudate serosanguineous (43,3%), in quantity medium/large (60,0%), with no predominance of presence or absence of odor (50,0%), all patients with tissue loss in grade III / IV, no signs of infection (73,3%) and presence of intense pain (50,0%). In the last 30 days the main venue of achievement of dressing was the HUOL (100,0%), the main compression therapy used was the Unna boot (60,0%) and on inability to perform the dressing on the unit were the own patients who made the exchange at home (40,0%). The majority of respondents listed out more positive factors associated with quality of care (56,7%) were satisfied with the care of SUS (76,7%), claimed to have knowledge about their rights (70,0%), but at the same time did not know the meaning of the acronym SUS (90,0%) and classified their level of information as inappropriate (70,0%). We realize that people with VU identified as good the quality of care and demonstrated inadequate knowledge about their rights to health in the SUS, but showed interest in acquiring more information. The basic rights to entry in the SUS are constitutionally guaranteed and need to be disseminated in order to make them known to the population, so it can be implemented and ensured a greater resolution assistance in treating this type of injury

Acurácia dos indicadores clínicos do diagnóstico de enfermagem volume de líquidos excessivo em pacientes submetidos à hemodiálise

Trasnversal study, with the objective of evaluating the accuracy of clinical indicators of nursing diagnosis excessive fluid volume in patients undergoing hemodialysis. The study occurred in two stages, the first consisted of the evaluation of the diagnostic indicators in study; and the second, the diagnostic inference conducted by nurse diagnosticians. The first stage occurred from december 2012 to april 2013, in a University Hospital and a Hemodialysis Clinic in Northeastern of Brazil, with a sample of 100 chronic renal failure patients on hemodialysis. The data were selected through an interview form and a physical examination, organized into spreadsheets and analyzed as to the presence or absence of the indicators of diagnosis excessive fluid volume. In the second step, the spreadsheets were sent to three nurses diagnosticians, who judged the presence or absence of diagnosis in the clientele searched. This step was conducted from july to september 2013. For analysis of the data, we used descriptive and inferential statistics. In the descriptive analysis, we used measures of central tendency and dispersion. In inferential analysis, we used the tests Chi- square, Fisher and prevalence ratios. The accuracy of the clinical indicators pertaining to the diagnosis were measured as to the specificity, sensitivity, predictive values, likelihood ratios and Diagnostic Odds Ratio. Also developed a logistic regression. The results were organized in tables and discussed with literature. This study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte, with Presentation Certificate for Ethics Appreciation nº 08696212.7.0000.5537. The results revealed that the diagnosis studied was present in 82% of patients. The characteristics with prevalence above 50 % that stood out were: azotemia, decreased hematocrit, electrolyte imbalance, intake exceeds output, anxiety, edema, decreased hemoglobin, oliguria and blood pressure changes. Eight defining characteristics were presented statistically significant association with the nursing diagnosis investigated: pulmonary congestion, intake exceeds output, electrolytes imbalance, jugular vein distension, edema, weight gain over short period of time, agitation and adventitious breath sounds. Among these, the 10 characteristics which showed higher prevalence ratios were: edema and weight gain over short period of time. The features with the highest sensitivity were edema, electrolytes imbalance and intake exceeds output and the standing out with greater specificity were: anasarca, weight gain over short period of time, change in respiratory pattern, adventitious breath sounds, pulmonary congestion, agitation and jugular vein distension. The indicators jugular vein distension, electrolytes imbalance, intake exceeds output, increased central venous pressure and edema, together, were identified in the logistic regression model as the most significant predictors. It is concluded that the identification of accurate clinical indicators allow a good prediction of the nursing diagnosis of excessive fluid volume in patients undergoing hemodialysis in order to assist the nurse in the inference process, which will contribute to the success of patient care. In addition, nurses will consider for diagnostic inference not only his clinical experience, but also scientific evidence of the occurrence of excessive fluid volume, contributing to the control of volemia in these patients

Autoestima e qualidade de vida de pessoas com úlcera venosa atendidas na atenção primária

Venous ulcers (VU) is a chronic injury of the lower extremities and because of its high incidence and recurrence implies long and complex treatments, damaging the quality of life (QOL) and self-esteem (SE) of the people. This study aimed to analyze the association between self-esteem with the quality of life of people with venous ulcers treated in primary care. Cross sectional analytical study with a quantitative approach conducted with 44 people met with VU at 13 primary care units 2 and Mixed units in Natal/RN. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte (UFRN), CAAE: 07556312.0.0000.5537. Held data collection from February to April 2014 and used three instruments: a structured form covering sociodemographic, health care and clinical variables, the Rosenberg Self-Esteem Scale and the SF-36. The collected data were entered into a database and processed on computerized software for descriptive and inferential analyzes. The results showed a predominance of people with UV females (65,9%), with more than 60 years (59,1%), married or in a stable relationship (52,3%), low education (86,4%) without occupation (68,2%) and less than one minimum wage income (81,8%). Regarding assistance characteristics was observed that most patients performed the dressing with appropriate material (72,7%), professional or trained caregiver (61,4%) did not use compression therapy (81,8%), treating the injury for more than 6 months (77,3%), lack of guidelines for the use of compression therapy, elevation of legs, and regular exercise (77,3%) and consulting the angiologist last year (52,3% ). Regarding clinical features of the lesion was found that most of the recurrent lesions are (77,3%), over one year of current lesion (52,3%) medium to large lesions (54,8%), without signs of infection (61,3%) and pain (79,5%). The mean SE of respondents was 9,3 (± 5,1). The relations between the SE and the sociodemographic variables, health care and clinics showed that individuals without a partner (a) (p = 0,01), who did not wear compression therapy (p = 0,04), with more 6 months of treatment (p = 0,01) and larger lesions (p = 0,01) had a lower SE. The mean domain and the dimensions of the SF-36 were lower emphasizing the functional capacity 36.5 (± 27,6) and the physical aspects of 15.3 (± 30,6). There were significant correlations between AE people with VU and the domains and dimensions of the SF-36: physical functioning (r = -0,432), general health (r = -0,415), vitality (r = -0,573), aspects social (r = -0,517), mental health (r = -0,612) and mental health dimensions (r = -0,612) and physical health (r = -0,473). Based on these results it is concluded by rejecting the null hypothesis and accept the alternative proposed in the study in which it was found that there is a negative correlation between the SE and the QOL of people with venous ulcers

Análise da adesão ao tratamento e da qualidade de vida de pessoas com úlcera venosa

The therapeutic adherence is still a big problem among people with venous ulcers (VU) because the treatment is long, expensive and demand changes in lifestyle. In this context, this study aims to examine treatment adherence and quality of life (QOL) of people with VU assisted at primary health care. This is an analytical, cross-sectional study with a quantitative approach to treatment and data analysis. The study had the scenario 13 Family Health Units and 02 Units Mixed of Natal. The target population consisted of 44 persons with UV indicated by the teams of the Family Health Strategy between February and April 2014. Three instruments were used: an instrument to characterize the sociodemographic, health and care aspects, the Multidimensional Scale of Adherence Therapy composed of the dimensions: healthy lifestyle, compressive therapy and neurovascular monitoring and the Charing Cross Venous Ulcer Questionnaire (CCVUQ) that evaluates QOL in persons with VU composed by the domains: Total Score, Social Interaction, Domestic Activities, Aesthetics and Emotional State. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte, CAAE: 07556312.0.0000.5537. The data concerning the sociodemographic characteristics showed that there was a predominance of females (65.9%), age range as of 60 years (59.1%) and income of up to 1 minimum wage (81.8%). With the characterization of health, it was evident that most people reported chronic diseases (63.6%), sleep more than 6 hours (81.8%), present pain (81.8%), denying alcoholism (86 4%) and smoking (77.3%) and showed a number greater than or equal to 1 (77.3%) recurrences. Concerning the therapeutic adherence was found that in the dimension compressive therapy there poor adherence. No associations between the domains of adherence and sociodemographic and health variables were found. Was observed, however, better adherence among individuals without pain and with higher schooling. When analyzed the averages of the dimensions of therapeutic adherence with the care characteristics there was statistical significance between: adherence to compression therapy and guidance for use of compressive therapy (p = 0.002) and guidance for regular exercise (p = 0.026). Considering the mean of total score of CCVUQ (mean 51.47, SD 18.33) it is observed that the overall QOL of respondents has approximate value of the median of the scale (50). The mean of the domain Social Interaction (mean 44.23, SD 21.38) and Domestic Activities (mean 45.70, SD 23.21) were those who reported better QOL. There were weak correlations but significant between adherence to healthy lifestyle and Domains Total Score (p = 0.012), social interaction (p-value = 0.048), Aesthetics (p-value = 0.025) and Emotional State (0.017) of CCVUQ. From the data analysis it is concluded that among people with UV, there poor adherence to compressive therapy. Furthermore, we found no statistically significant association between treatment adherence and sociodemographic and health characteristics. It is added that there was a correlation between the healthy lifestyle dimension and domains CCVUQ

Influência do tratamento periodontal sobre os níveis da proteína c-reativa ultrassensível em pacientes com insuficiência renal crônica em fase de prétransplante

The present study evaluated the influence of non-surgical periodontal treatment on the levels of C- reactive protein (hsCRP) in patients with chronic renal failure (CRF) in pretransplant. We conducted a controlled and randomized trial to evaluate the periodontal condition and plasma concentrations of hsCRP, albumin and transferrin in 56 dialysis patients divided into two groups: experimental and control. The study was conducted at the dental clinic of Family and Community Health s Unit (USFC), located in Onofre Lopes University Hospital (HUOL), Federal University of Rio Grande do Norte (UFRN), from December 2010 to November 2011. Severe periodontitis was the type of periodontal disease more common, affecting 78.6% of patients. Periodontal conditions, evaluated through the means of probing depth, clinical attachment level, bleeding index and plaque index, proved to be uniform for both groups at the initial examination. There were no differences in levels of inflammatory markers between the two groups. The analysis of the concentrations of hsCRP allowed classifying study participants as at high risk of developing cardiovascular disease. After completion of periodontal treatment in the experimental group, there was a statistically significant reduction of the mean of all periodontal parameters assessed; however this improvement of periodontal health was not accompanied by changes in the levels of hsCRP, albumin and transferrin in the evaluation time. Given this, the periodontal treatment did not promote the reduction of systemic inflammatory burden and risk of cardiovascular complications in patients with CRF

Fatores de risco pré-operatórios para o desenvolvimento de Insuficiência Renal Aguda em cirurgia cardíaca

OBJETIVO:Avaliar os fatores de risco clínicos pré-cirurgicos para o desenvolvimento de Insuficiência Renal Aguda (IRA) em pacientes submetidos à cirurgia cardíaca. MÉTODO: Foram estudados, de modo prospectivo, 150 pacientes submetidos à cirurgia cardíaca, durante 21 meses consecutivos, havendo um leve predomínio de homens (57%), idade média de 56 ± 15 anos, sendo que 66% apresentavam insuficiência coronariana como principal diagnóstico e 34% valvulopatias. A mediana da creatinina sérica no período pré-operatório foi de 1,1 mg/dl. IRA foi definida como elevação de 30% da creatinina sérica basal. O protocolo de variáveis clínicas teve seu preenchimento iniciado 48 horas antes do procedimento cirúrgico e encerrado 48 horas após o mesmo, incluindo variáveis cardiológicas e não-cardiológicas, além de resultados laboratoriais. RESULTADOS: A IRA esteve presente em 34% dos casos. Após análise multivariada, presença de doença vascular periférica foi fator pré-operatório identificado. CONCLUSÃO: Os resultados obtidos nesse estudo permitiram sinalizar alguns fatores contributivos para o desenvolvimento de IRA em cirurgia cardíaca, o que pode possibilitar condutas clínicas simples para evitar a disfunção renal nestas situações e, conseqüentemente, redução da taxa de mortalidade. No presente trabalho, o tamanho da amostra talvez tenha impedido a identificação de outros fatores de risco significativos.

Trombose venosa profunda de membros superiores: estudo coorte retrospectivo de 52 casos

OBJETIVO: Rever os fatores predisponentes e a evolução em série de casos de trombose venosa profunda dos membros superiores de nossa instituição. MÉTODOS: Cinqüenta e dois pacientes consecutivos, com trombose venosa profunda dos membros superiores (29 homens e 23 mulheres), idade média de 52,3 anos, documentados por mapeamento dúplex (71,1%), flebografia (11,1%) ou clinicamente (15,6%), foram incluídos no presente estudo. RESULTADOS: As manifestações clínicas foram: dor no antebraço (24 casos - 46,1%), dor no braço (27 casos - 51,9%), edema do membro superior (45 casos - 86,5%), dor à compressão do membro superior (36 casos - 70,2%) e dor à movimentação do mesmo (32 casos - 61,7%). Os principais fatores de risco foram: punção ou acesso venoso (20 casos - 39,1%) e câncer (16 casos - 32,6%). As veias envolvidas foram: umeral (n = 18), axilar (n = 27), subclávia (n = 15) e jugular (n = 11). A embolia pulmonar estava inicialmente presente em quatro casos (7,6%). O tratamento inicial foi feito com heparina não-fracionada intravenosa (64,3%), subcutânea (16,7%), ou heparina de baixo peso molecular (17,1%), seguido de varfarina. Doze pacientes morreram antes da alta, em função de causas não relacionadas à embolia pulmonar. Foram acompanhados os 40 pacientes restantes por período de 3 meses a 10 anos, sendo que dois morreram de causas não relacionadas à embolia pulmonar, um paciente desenvolveu seqüelas pós-trombóticas, como edema residual e limitações aos movimentos, e seis ficaram com discretos sintomas residuais (edema e dor). CONCLUSÕES: A trombose venosa profunda dos membros superiores foi mais freqüente em pacientes submetidos a acessos venosos e com neoplasia em atividade. Comparando com dados da literatura, a evolução dos pacientes sob tratamento exclusivo com anticoagulantes foi, no mínimo, similar a outros tratamentos propostos.

O papel do mapeamento dúplex no diagnóstico da trombose venosa profunda assintomática dos membros inferiores

O diagnóstico da trombose venosa profunda sintomática está bem estabelecido com o uso do mapeamento dúplex, que apresenta sensibilidade de 100% e especificidade de 98%, para trombose venosa profunda proximal, e sensibilidade de 94% e especificidade de 75%, para distal. Na trombose venosa profunda recente e assintomática, o diagnóstico com o mapeamento dúplex ainda não está bem estabelecido, mostrando uma queda na acurácia desse método diagnóstico. Essa queda é devida ao fato de o trombo recente não ser oclusivo, apresentar a mesma ecogenicidade do sangue e uma consistência diminuída, prejudicando o teste da compressibilidade, que é o mais sensível para diagnóstico da trombose venosa profunda. Nesta revisão, serão revistos artigos publicados que avaliaram a acurácia do mapeamento dúplex no diagnóstico da trombose venosa profunda assintomática.

Acesso vascular para hemodiálise com cateter temporário de duplo lúmen em cães com insuficiência renal aguda

A hemodiálise é uma modalidade terapêutica que pode sustentar a vida do paciente com insuficiência renal aguda (IRA), enquanto este recupera a função renal. Para sua realização, é necessário estabelecer circulação extracorpórea, para que seja realizada a filtração do sangue, impondo a necessidade de um acesso vascular viável e eficiente. O objetivo deste estudo foi avaliar a eficiência e as complicações do acesso vascular para hemodiálise (HD), com cateter temporário de duplo lúmen inserido na veia jugular externa. Foram estudados 10 cães com IRA induzida por gentamicina, submetidos a sessões diárias de HD, com duração de uma hora, até a recuperação da função renal ou óbito. Foram realizadas 104 sessões de HD nos animais estudados, observando-se necessidade de troca do cateter em sete sessões (6,7%), devido à obstrução do lúmen do cateter em seis sessões (5,8%) ou por saída acidental do mesmo em uma sessão (1,0%). Não se observou migração do cateter, infecção, hemorragia ou hematoma no local de entrada do cateter na pele, obtendo-se fluxo sanguíneo patente em 90,4% das sessões. Concluiu-se que o acesso vascular na veia jugular externa com cateter temporário de duplo-lúmen mostrou-se viável, com ocorrência de poucas complicações, sendo, portanto, indicado como forma de acesso para a circulação extracorpórea para HD em cães com IRA.

Avaliação do modelo de predição clínica de Wells et al. no diagnóstico da trombose venosa profunda dos membros inferiores

CONTEXTO: A aplicação de uma estratégia baseada em um modelo clínico associado ao mapeamento dúplex (MD) pode permitir um diagnóstico da trombose venosa profunda (TVP) mais seguro, eficaz e custo-efetivo. OBJETIVO: Testar o modelo clínico de Wells et al. associado ao MD e verificar a ocorrência de TVP nos pacientes categorizados quanto à probabilidade de apresentar a doença, e determinar se, a partir dos resultados obtidos, seria possível reduzir o número de exames seriados com o MD. MÉTODOS: Os pacientes com suspeita clínica de TVP foram categorizados quanto à apresentação de TVP em baixa, moderada e alta probabilidade (BP, MP, AP) e, em seguida, submetidos ao MD. Pacientes com MD negativo repetiram o exame em 24-48 horas e em 7 dias. Pacientes com exame positivo para TVP foram tratados. Todos os pacientes sem TVP foram convocados para reavaliação clínica em 3 meses. RESULTADOS: A ocorrência de TVP entre os 489 pacientes avaliados foi de 39,1% (191), sendo 35,6% identificados no exame inicial e 3,5% no exame seriado. Os índices de pacientes que apresentaram TVP foram de 6,1% no grupo de BP, 26,9% no grupo de MP e 79,5% no grupo de AP. No exame seriado, o percentual de TVP foi de 2,4, 7,8 e 15,1% nos grupos BP, MP e AP, respectivamente. Dos pacientes com MD negativo, 62,4% compareceram após 3 meses, e piora dos sintomas foi apresentada por apenas um paciente. Neste, o MD mostrou TVP de veia poplítea. CONCLUSÃO: Os resultados obtidos sugerem que, para os pacientes com BP para TVP e MD negativo, seria possível prescindir do exame seriado, devido à baixa ocorrência de TVP neste grupo, tornando, assim, a abordagem diagnóstica mais simples.

Estudo comparativo entre protocolos para profilaxia da trombose venosa profunda: uma nova proposta

INTRODUÇÃO: O artigo compara os protocolos Davison-Caprini (americano) e Sandri (brasileiro) para profilaxia da trombose venosa profunda (TVP), buscando a elaboração de um novo protocolo, mais abrangente e aplicável. MÉTODO: Foi realizado um estudo prospectivo, durante um ano, abrangendo 212 pacientes, comparando os protocolos quanto à estratificação de risco de TVP, e ao tipo de profilaxia indicado. Um novo protocolo foi proposto, aplicado e comparado aos anteriores. RESULTADOS: Obteve-se um novo protocolo, denominado Sandri modificado, que restringe a heparina a um grupo seleto de pacientes, semelhante ao americano, mantendo-se adequado tanto para cirurgias estéticas quanto reparadoras. CONCLUSÕES: A baixa adesão, por parte dos cirurgiões plásticos, ao uso rotineiro da profilaxia de TVP, espelha a escassez de informação sobre o tema. O protocolo Sandri modificado busca melhorar a compreensão e a aplicabilidade da profilaxia da TVP na cirurgia plástica.
