Protocolo gerenciado de tratamento do potencial doador falecido reduz incidência de parada cardíaca antes do explante dos órgãos / A managed protocol for treatment of deceased potential donors reduces the incidence of cardiac arrest before organ explant

OBJETIVO: Avaliar o efeito da aplicação de um protocolo gerenciado de manutenção de potenciais doadores falecidos de múltiplos órgãos em duas unidades hospitalares. MÉTODOS: Estudo antes (Fase 1)/depois (Fase 2) realizado em dois hospitais gerais que incluiu, consecutivamente, os potenciais doadores ingressados em duas unidades de terapia intensiva. Na Fase 1 (16 meses), os dados foram coletados retrospectivamente e as medidas de manutenção do potencial doador foram instituídas a critério do intensivista. Na Fase 2 (12 meses), a coleta de dados foi prospectiva e a manutenção foi guiada por um protocolo gerenciado. As duas fases foram comparadas entre si de acordo com variáveis demográficas, variáveis fisiológicas no diagnóstico da morte encefálica e ao final do processo, tempo necessário para realização do exame confirmatório de morte encefálica e final do processo, aderência aos conjuntos de medidas essenciais de manutenção (pacotes), perdas por parada cardíaca, perdas por negativa familiar, perdas por contraindicação e taxa de conversão de potenciais doadores em doadores reais. Foram aplicados os testes de t-Student e do qui-quadrado, e o valor de p<0,05 foi considerado significativo. RESULTADOS: Identificaram-se 42 potenciais doadores (18 na Fase 1 e 24 na Fase 2). Houve diminuição do tempo entre a primeira exploração clínica e o explante (Fase 1: 35,0±15,5 horas versus Fase 2: 24,6±6,2 horas; p=0,023). Houve aumento na aderência em 10 dos 19 itens essenciais de manutenção, e redução nas perdas por parada cardíaca (Fase 1: 27,8 versus 0% na Fase 2; p=0,006) com aumento de doadores reais (Fase 1: 44,4 versus 75% na Fase 2; p=0,044). Não houve mudança nas perdas por negativa familiar ou por contraindicação médica. CONCLUSÃO: A adoção de um protocolo gerenciado promove a aplicação de medidas essenciais no cuidado do potencial doador falecido e pode reduzir as perdas de potenciais doadores por parada cardíaca.

OBJECTIVE: To assess the effect of the application of a managed protocol for the maintenance care of deceased potential multiple organ donors at two hospitals. METHODS: A before (Phase 1)/after (Phase 2) study conducted at two general hospitals, which included consecutively potential donors admitted to two intensive care units. In Phase 1 (16 months), the data were collected retrospectively, and the maintenance care measures of the potential donors were instituted by the intensivists. In Phase 2 (12 months), the data collection was prospective, and a managed protocol was used for maintenance care. The two phases were compared in terms of their demographic variables, physiological variables at diagnosis of brain death and the end of the process, time to performance of brain death confirmatory test and end of the process, adherence to bundles of maintenance care essential measures, losses due to cardiac arrest, family refusal, contraindications, and the conversion rate of potential into actual donors. Student's t- and chi-square tests were used, and p-value < 0.05 was considered to be significant. RESULTS: A total of 42 potential donors were identified (18 in Phase 1 and 24 in Phase 2). The time interval between the first clinical assessment and the recovery decreased in Phase 2 (Phase 1: 35.0±15.5 hours versus Phase 2: 24.6±6.2 hours; p = 0.023). Adherence increased to 10 out of the 19 essential items of maintenance care, and losses due to cardiac arrest also decreased in Phase 2 (Phase 1: 27.8 versus 0% in Phase 2; p = 0.006), while the convertion rate increased (Phase 1: 44.4 versus 75% in Phase 2; p = 0.044). The losses due to family refusal and medical contraindication did not vary. CONCLUSION: The adoption of a managed protocol focused on the application of essential measures for the care of potential deceased donors might reduce the loss of potential donors due to cardiac arrest.

[Analysis of quality of life following hospital discharge among survivors of severe sepsis and septic shock]. / Análise da qualidade de vida após a alta hospitalar em sobreviventes de sepse grave e choque séptico.

OBJECTIVE: Describe the impact of severe sepsis and septic shock on patients' quality of life following hospital discharge. METHODS: A controlled study conducted in two general hospitals of Joinville, Santa Catarina, Brazil, of in-patients with severe sepsis or septic shock during the period of August 2005 through November 2007. The patients were contacted by telephone between June and November 2009. The study group responded to Short Form-36, a questionnaire on the quality of life, two years after being discharged from hospital. The questionnaire was also answered by a control group composed of people who lived at the same residence as the study subjects, had no recent hospitalization, and were close in age. RESULTS: Of 217 patients with severe sepsis or septic shock, 112 (51.6%) survived hospitalization. The survival rate after hospital discharge was 41.02% at 180 days, 37.4% at one year, 34.3% at 18 months, and 32.3% in two years. Thirty-six survivors responded to Short Form-36. There were declines in the quality of life for survivors (No. = 36) in comparison to the control group (No. = 36) in the following areas: physical functioning (59 ± 32 versus 91 ± 18; P < 0.001), vitality (48 ± 13 versus 59 ± 14; P < 0.008), mental health (48 ± 13 versus 59 ± 14; P < 0.03), bodily pain (50 ± 26 versus 76 ± 16; P < 0.001), general health perceptions (53 ± 18 versus 67 ± 13; P < 0.004), physical role functioning (67 ± 45 versus 85 ± 34; P < 0.05), and social role functioning (70 ± 28 versus 90. ± 16; P < 0.05). CONCLUSIONS: Severe sepsis or septic shock can result in significant negative effects on the quality of life, in addition to reducing long-term survival probability.

Diretrizes para manutenção de múltiplos órgãos no potencial doador adulto falecido: Parte III. Recomendações órgãos específicas / Guidelines for potential multiple organ donors (adult). Part III: organ-specific recommendations

A morte encefálica induz várias alterações fisiopatológicas que podem causar lesões em rins, pulmões, coração e fígado. Portanto, a atuação do intensivista durante a manutenção do potencial doador falecido exige cuidados específicos com estes órgãos visando sua maior viabilidade para transplantes. O manejo hemodinâmico cuidadoso, os cuidados ventilatórios e de higiene brônquica minimizam a perda de rins e pulmões para o transplante. A avaliação da condição morfológica e funcional do coração auxilia na avaliação do potencial transplantável deste órgão. Por fim, a avaliação da função hepática, assim como o controle metabólico e a realização de sorologias virais são fundamentais para a orientação das equipes transplantadoras na seleção do órgão a ser doado e no cuidado com o receptor.

Brain death (BD) alters the pathophysiology of patients and may damage the kidneys, the lungs, the heart and the liver. To obtain better quality transplant organs, intensive care physicians in charge of the maintenance of deceased donors should attentively monitor these organs. Careful hemodynamic, ventilatory and bronchial clearance management minimizes the loss of kidneys and lungs. The evaluation of cardiac function and morphology supports the transplant viability assessment of the heart. The monitoring of liver function, the management of the patient's metabolic status and the evaluation of viral serology are fundamental for organ selection by the transplant teams and for the care of the transplant recipient.

A desproporção entre a grande demanda por transplantes de órgãos e a baixa realização de transplantes é um grave problema de saúde pública. O reconhecimento da morte encefálica, a adequada abordagem da família e a manutenção clínica do doador falecido são fundamentais para a diminuição desta desproporção. Neste cenário, o intensivista tem importância central e a aplicação do conjunto de informações disponíveis para manutenção do potencial doador falecido está claramente associada à redução de perdas de doadores e ao aumento da qualidade e da efetivação de transplantes.

There is a relative shortage of appropriate organs available for transplantation. The appropriate diagnosis of brain death, a suitable family approach and the maintenance of the deceased donor are fundamental in addressing this issue. The intensive care physician plays a key role in the maintenance of the deceased donor, thereby reducing losses and increasing the number of successful transplants.

Ventilação mecânica, controle endócrino metabólico e aspectos hematológicos e infecciosos / Guidelines for potential multiple organ donors (adult): part II. Mechanical ventilation, endocrine metabolic management, hematological and infectious aspects

A atuação do intensivista durante a manutenção do potencial doador falecido na busca da redução de perdas de doadores e do aumento da efetivação de transplantes não se restringe aos aspectos hemodinâmicos. O adequado controle endócrino-metabólico é essencial para a manutenção do aporte energético aos tecidos e do controle hidro-eletrolítico, favorecendo inclusive a estabilidade hemodinâmica. A abordagem das alterações hematológicas é igualmente importante considerando as implicações da prática transfusional inapropriada. Ressalta-se ainda o papel da ventilação protetora na modulação inflamatória e conseqüente aumento do aproveitamento de pulmões para transplante. Por fim, assinala-se a relevância da avaliação criteriosa das evidências de atividade infecciosa e da antibioticoterapia na busca do maior utilização de órgãos de potenciais doadores falecidos.

The role of intensive care specialists in the maintenance of deceased potential donors is not restricted to hemodynamics. Appropriate endocrine-metabolic management is fundamental to maintaining energy support and hydroelectrolytic control, which cooperate for hemodynamic stability. Hematological changes are also important, especially considering the issues caused by inappropriate transfusions. In addition, this article discusses the role of appropriate protective ventilation to prevent inflammatory responses and to provide more transplantable lungs. Finally, judicious assessment of infections and antibiotic therapy is discussed.

[Assessment of patients with pressure sores admitted in a tertiary care center]. / Avaliação dos pacientes portadores de lesão por pressão internados em hospital geral.

BACKGROUND: To determine the prevalence and analyze the profile of patients with pressure sores, focusing on risk factors, the patients' clinical characteristics at a tertiary care center, as well as stage and location of the lesions on the body. METHODS: This was a cross sectional not controlled observational study, all patients admitted from April to June of 2005 were observed daily to identify all cases of pressure sores. The affected patients were evaluated by a standard questionnaire and the Scale of Braden was applied to define the risk of developing ulcers. RESULTS: Of the 690 patients admitted during the referred period, a prevalence of 5.9% of patients with lesions was observed, equivalent to 41 patients 63.9% of which were elderly and the average length of stay was 18 days. In the sample studied 41.5% of patients were found in the internal medicine section and the intensive care unit, ICU. The most common location for sores was the sacral area, corresponding to 73.1% of the patients, and stage II was the most frequent, observed in 58.5% of those patients. According to the Braden scale, most patients, 80.4%, had a high risk of developing pressure ulcers, compared to 9.7% of patients with moderate risk and 7.4% with low risk. CONCLUSION: The affected patients were at high risk of developing pressure sores. Prevalence of these lesions and the clinical and demographic profile of the affected patients are in accordance with the data in literature.
