A presente tese explora aspectos importantes do suporte nutricional, no paciente crítico: método e vias de administração da nutrição enteral, determinação do gasto energético, monitorização da adequação do suporte nutricional e seu efeito sobre os desfechos em curto e longo prazo. Em face da evidência de benefícios significativos, a nutrição enteral é recomendada como a primeira opção para a maioria dos pacientes, quando comparada à nutrição parenteral. É comum a intolerância gástrica associada ao uso de opióides, choque e vasopressores, o que reduz a entrega de energia e talvez aumente a incidência de pneumonia hospitalar. A subalimentação parece estar associada com consequências indesejáveis, que incluem o risco aumentado de infecção, o desmame da ventilação prolongada, o tempo de internação na UTI e as taxas elevadas de mortalidade, na UTI e no hospital. A determinação do gasto energético é alvo de debates, pois vários são os fatores que influenciam diretamente o gasto energético do paciente crítico. O método calorimetria indireta é apontado como o mais preciso para adequar o suporte nutricional, quando comparado com as equações preditivas. Vale destacar, porém, que ainda é necessária maior evidência clínica sobre a real influência da calorimetria indireta nos desfechos clínicos (Tempo em VM, tempo de UTI e mortalidade em UTI, mortalidade hospitalar). Os estudos avaliam os desfechos clínicos mais relevantes, em curto prazo, e há uma escassez de estudos que avaliam a qualidade de vida dos sobreviventes, em médio ou longo prazo. Para a realização da tese, foram desenvolvidos três estudos, um ensaio clínico randomizado, em que foi definida a incidência de pneumonia e avaliada a taxa de mortalidade na UTI, comparando a nutrição por sonda gástrica com a por sonda jejunal. Não encontramos diferença na taxa de pneumonia, quando é utilizada a sonda em posição gástrica ou jejunal. Não observamos diferenças na sobrevida na UTI e hospitalar. Em nossa revisão sistemática, analisamos quatro artigos da literatura sobre paciente crítico adulto e adequação do suporte nutricional guiado pela calorimetria indireta, de 1950 a maio de 2014. Não encontramos estudos suficientes para evidenciar o impacto da utilização da calorimetria indireta, como método de adequação do suporte nutricional sobre os desfechos clínicos. Realizamos estudo observacional, onde procuramos definir as relativas contribuições da adequação nutricional maior ou igual a 70%, em relação ao previsto nas primeiras 72 horas de internação na UTI, para os desfechos clínicos em curto e longo prazo (capacidade de realizar atividades da vida diária). Os pacientes que receberam um aporte calórico igual ou superior a 70%, nas primeiras 72 horas de internação, não apresentaram melhores desfechos em curto prazo (tempo em VM, tempo de UTI e mortalidade em UTI), bem como melhora da capacidade funcional em um ano. Esta tese se justifica por buscar melhor entendimento dos principais aspectos do suporte nutricional enteral, no paciente crítico, mecanicamente ventilado e submetido à terapia intensiva. Como aspectos da terapia nutricional, destacamos a importância de investigar evidências clínicas do impacto do suporte nutricional enteral sobre desfechos clínicos. / This thesis explores important aspects of nutritional support in critically ill patients: method and routes for enteral nutrition administration; determining energy expenditure; monitoring the optimal nutritional support and its effect on short- and long-term outcomes. Given the evidence of significant benefits, enteral nutrition is recommended as the first choice for most patients compared to parenteral nutrition. Gastric intolerance associated with opioid use, shock, and vasopressors is common, which reduces energy delivery and may increase the incidence of hospital-acquired pneumonia. Malnutrition appears to be associated with undesirable consequences, including increased risk of infection; weaning from prolonged ventilation; length of stay in ICU; and high mortality rates in ICU and hospital. Determining energy expenditure is subject to debate because several factors directly influence it for critically ill patients. The method of indirect calorimetry is pointed out as the most accurate for establishing adequate nutritional support compared with predictive equations. It is worth noting, however, that more clinical evidence is needed on the real influence of indirect calorimetry on clinical outcomes (length of ventilation; length of stay in ICU and mortality in ICU; hospital mortality). The studies evaluate the most relevant clinical outcomes in the short term, and there is shortage of works assessing survivors’ quality of life in the medium or long term. Three studies were developed for the thesis: a randomized clinical trial where the incidence of pneumonia was established and the mortality rate in ICU was evaluated, comparing nutrition by gastric gavage with a jejunal probe. No difference was found in the rate of pneumonia when using the gavage in gastric or jejunal position. No differences in survival in ICU and hospital were found. In our systematic review, we analyze four articles on critically ill adult patients and optimization of nutritional support guided by indirect calorimetry, from 1950 to May 2014. We did not find enough studies to show the impact of using indirect calorimetry for optimizing nutritional support on clinical outcomes. We conducted an observational study to define the relative contributions of nutritional optimization higher or equal to 70% relative to predictions in the first 72 hours of ICU admission for clinical outcomes in the short and long term (ability to perform daily activities). Patients who received caloric intake equal to or higher than 70% in the first 72 hours of admission did not show better outcomes in the short term (time under MV, ICU stay, and ICU mortality) as well as improved functional capacity within one year. This thesis is justified for seeking to improve understanding of the key aspects of enteral nutritional support in critically ill, mechanically ventilated patients who have underwent intensive therapy. Important aspects of nutrition therapy include investigating clinical evidence of the impact of enteral nutritional support on clinical outcomes.

Bakgrund: Intensivvården karaktäriseras av högteknologisk utrustning och specialistdriven vård för patienter i kritiskt tillstånd. Arbetet med kritiskt sjuka patienter är komplext och utförs i en ansträngd miljö med hög risk för mortalitet. Samverkan i team är avgörande för att säkerställa kontinuitet och patientsäkerhet. Intensivvårdssjuksköterskan har en central funktion i arbetet med både medicinska och omvårdnadsrelaterade uppgifter. Syfte: Syftet var att belysa intensivvårdssjuksköterskors erfarenhet av att vårda en kritiskt sjuk patient på en intensivvårdsavdelning. Metod: Kvalitativ innehållsanalys med induktiv ansats. Tio intensivvårdssjuksköterskor intervjuades genom en semistrukturerad metod. Resultat: Analysen resulterade i fyra kategorier, “samarbetet är centralt”, “omvårdnaden omprioriteras”, “erfarenheten har betydelse” och “stimulerande arbete” samt åtta subkategorier. Konklusion: Studiens resultat visar att intensivvårdssjuksköterskor erfar många utmaningar inom arbetet. Trots svårigheter framträder en gemensam känsla av ansvar och tillfredsställelse. Teamarbete är essentiellt för att säkerställa bästa möjliga vård. Studien belyser även behovet av stöd för främst nya men också erfarna intensivvårdssjuksköterskor för att hantera den komplexa arbetsmiljön. I den mångfacetterade utmaningen kan omvårdnaden behöva omprioriteras för akuta medicinska åtgärder. / Background: The intensive care is characterized by high-tech equipment and specialist-driven care for critically ill patients. The care for critically ill patients is complex and performed in a stressful environment with a high risk of mortality. Team collaboration is essential to secure continuity and patient safety. The intensive care nurse has a key role with both medical intervention and care-related duties. Aim: The aim was to illustrate intensive care nurses' experience in caring for a critically ill patient in an intensive care unit. Method: A qualitative content analysis with an inductive approach. Ten intensive care nurses were interviewed using a semi-structured method. Results: The analysis resulted in four categories: “collaboration is central”, “care is reprioritized”, “experience matter” and “stimulating work” along with eight subcategories. Conclusion: The study’s findings indicate that intensive care nurses face many challenges in their work. Despite these difficulties, a common feeling of responsibility and satisfaction emerges. Teamwork is essential to ensure the best possible care. The study also highlights the need for support, primarily for new but also experienced intensive care nurses, to manage the complex work environment. In the multifaceted challenge, care may need to be reprioritized for urgent medical interventions.

BACKGROUND:Anticoagulation with vitamin K antagonists such as warfarin has historically been used for the long term management of patients with thromboembolic disease. However, these agents have a slow onset of action which requires bridging therapy with heparin and its analogues, which are available only in parenteral route. To overcome these limitations, new oral anticoagulants such as factor Xa inhibitors and direct thrombin inhibitors have been developed. The aim of this article is to systematically review the phase 3 clinical trials of new oral anticoagulants in common medical conditions.METHODS:We searched PubMed (Medline) from January 2007 to February 2013 using "Oral anticoagulants", "New oral anticoagulants", "Randomized controlled trial", "Novel anticoagulants", "Apixaban", "Rivaroxaban", "Edoxaban", "Dabigatran etexilate", "Dabigatran" and a combination of the above terms. The available evidence from the phase 3 RCTs was summarized on the basis of individual drug and the medical conditions categorized into "atrial fibrillation", "acute coronary syndrome", "orthopedic surgery", "venous thromboembolism" and "medically ill patients".RESULTS:Apixaban, rivaroxaban and dabigatran have been found to be either non-inferior or superior to enoxaparin in prophylaxis of venous thromboembolism in knee and hip replacement with similar bleeding risk, superior to warfarin for stroke prevention in atrial fibrillation with significant reduction in the risk of major bleeding, non-inferior to aspirin for reducing cardiovascular death and stroke in acute coronary syndrome with significant increase in the risk of major bleed. Rivaroxaban and dabigatran are also superior to the conventional agents in the management of symptomatic venous thromboembolism. However, compared to enoxaparin, apixaban and rivaroxaban use lead to significantly increased bleeding risk in medically ill patients. Additional studies evaluating the specific reversal agents of these new drugs for the management of life-threatening bleeding or other adverse effects are necessary.CONCLUSION:Considering their pharmacological properties, their efficacy and bleeding complications, the new oral agents offer a net favourable clinical profile in orthopedic surgery, atrial fibrillation, acute coronary syndrome and increase the risk of bleeding in critically ill patients. Further studies are necessary to determine the long term safety and to identify the specific reversal agents of these new drugs.

Introdução: Há poucos estudos avaliando qualidade de vida relacionada à saúde (QVRS) e anos de vida ajustados para qualidade de vida (QALY) em pacientes com câncer que necessitam internação em unidades de terapia intensiva. O objetivo deste estudo foi avaliar sobrevida, QVRS e QALY durante o seguimento a longo prazo de pacientes com câncer internados em UTI. Métodos: Realizamos uma coorte prospectiva de pacientes com câncer admitidos em duas UTIs do estado de São Paulo. Coletamos dados na admissão da UTI, incluindo QVRS antes da doença aguda que motivou internação em UTI e no seguimento em 15 dias, 3 meses, 6 meses, 12 meses e 18 meses para avaliar a QVRS e status vital. Adicionalmente, o status vital foi avaliado em 24 meses. QVRS foi determinada com o questionário EQ-5D-3L. A sobrevida foi calculada com o estimador de Kaplan-Meier e o QALY com uma adaptação do estimador Zhao e Tsiatis. Resultados: Foram incluídos 792 pacientes. A média de idade foi 61,6±14,3 anos, 42,5% dos pacientes eram do sexo feminino e metade foi admitida após cirurgia eletiva. A média do escore SAPS3 foi 47,4±15.6. A probabilidade de sobreviver 12 e 18 meses foi 42.4% e 38.1%, respectivamente. A média do índice de utilidade da QVRS antes da internação na UTI foi 0,47±0,43, aos 15 dias pós-admissão a UTI 0,41±0,44, aos 3 meses 0,56±0,42, aos 6 meses 0,60±0,41, aos 12 meses 0,67±0,35 e aos 18 meses 0,67±0,35. A probabilidade de atingir 12 e 18 meses de vida ajustados para qualidade de vida foi de 30.1% e 19.1%, respectivamente. Houve diferenças estatisticamente significativas do tempo de sobrevida e QALY conforme as características de base consideradas (admissão após cirurgia eletiva, cirurgia de urgência ou clínica; SAPS3; extensão do câncer; status do câncer; cirurgia prévia; quimioterapia prévia; radioterapia prévia; capacidade funcional; e QVRS prévia). No entanto, apenas QVRS prévia e capacidade funcional foram associados a QVRS ao longo do seguimento de 18 meses. Conclusão: Em pacientes com câncer admitidos em UTI, a sobrevida, QVRS e QALY a longo prazo são limitados. Entretanto, há bastante variabilidade entre os pacientes nestes desfechos clínicos que é associada a características simples presentes na admissão à UTI e que podem auxiliar a equipe de saúde a avaliar o prognóstico / Introduction: Only few studies assessed health-related quality of life (HRQOL) and quality-adjusted life years (QALY) of cancer patients admitted to intensive care units (ICU). We aimed to assess the long-term HRQOL and QALY of cancer patients admitted to ICUs. Methods: We conducted a prospective cohort study of cancer patients admitted to two ICUs from the state of São Paulo, Brazil. We assessed the HRQOL with the EQ-5D-3L before ICU admission, 15 days, 3, 6, 12 and 18 months. In addition, the vital status was assessed at 24 months. Survival was calculated with the Kaplan-Meier estimator and QALY with the adapted Zhao and Tsiatis estimator. Results: The mean age of the subjects was 61.6 ± 14.3 years, 42.5% were female and half were admitted after elective surgery. The mean Simplified Acute Physiology Score (SAPS) 3 was 47.4 ± 15.6. Survival at 12 and 18 months was 42.4% and 38.1%, respectively. The mean EQ5D utility measure before admission to the ICU was 0.47±0.43, at 15 days it was 0.41±0.44, at 90 days 0.56±0.42, at 6 months 0.60±0.41, at 12 months 0.67±0.35 and at 18 months 0.67±0.35. The probabilities for attaining 12 and 18 months of quality-adjusted survival were 30.1% and 19.1%, respectively. There were statistically significant differences in survival time and QALYs according to all assessed baseline characteristics (ICU admission after elective surgery, emergency surgery or medical admission; SAPS3; cancer extension; cancer status; previous surgery; previous chemotherapy; previous radiotherapy; performance status; and previous HRQOL). Only the previous HRQOL and performance status were associated with the HRQOL during the 18-month follow-up. Conclusion: Long-term HRQOL, survival and QALY expectancy of cancer patients admitted to the ICU are limited. Nevertheless, these clinical outcomes exhibit wide variability among patients and are associated with simple characteristics present at the time of ICU admission, which may help healthcare professionals estimate patients\' prognose

Achieving energy and protein targets in these patients is a daily challenge for the care team in the intensive care setting. Objective: To monitor the energy and protein delivery and the inadequacies of ENT in critically ill patients admitted to an intensive care unit (ICU). Method: In this prospective longitudinal study, 82 patients admitted in the ICU of an university hospital were studied. The following variables were evaluated: energetic and protein goals of ENT, the prescribed and delivered ENT, the causes and frequencies of the insufficient delivery and enteral nutrition outcomes. These patients had their nutritional diagnosis defined by anthropometric parameters, laboratory tests and nutritional risk screening tools (NUTRIC score and nutritional risk screening). For the statistical analysis, the Wilcoxon test, the Chi-square test or the Fisher exact test and the Mann-Whitney test were used. Results: The average energy goal was 2132.91 kcal and protein goal was 113.96 g per day. The average energy delivery was 53.44% of the target and protein was 43.72% of the target, a statistically significant difference for both variables (p<0.0001). There was a statistically significant difference (p<0.0001) for all comparisons made between the goal, prescription and infusion of ENT. The average energy prescribed was 68% (p<0,0001) of the target, and 53% (p<0,0001) of the energy target was delivered. The average protein prescribed was 58% (p<0,0001) of the target, and only 43% (p<0,0001) of was delivered. The patients received 72% of what was prescribed for both, energy and protein. All patients presented an inadequacy of the ENT delivery and for 90%, there was no justification for the delay of the ENT delivery. Half (50%) of the patients in ENT were at nutritional risk. Conclusion: The ENT does not meet entirely the critically ill patients energy and protein needs. The complications that affect these patients interrupts the delivery of the ENT, as well as preventable delays. Such findings consolidate the importance of adequate and careful monitoring of ENT in critically ill patients. / Introdu??o: A terapia nutricional enteral (TNE) ? a via de escolha preferencial para nutrir pacientes graves e tem como principal objetivo prevenir e tratar as defici?ncias nutricionais e a desnutri??o hospitalar. Atingir as metas energ?ticas e proteicas nestes pacientes ? um desafio di?rio para a equipe de cuidados no ambiente da terapia intensiva. Objetivo: Monitorar a oferta energ?tica e proteica e as inadequa??es da TNE em pacientes cr?ticos internados em uma unidade de terapia intensiva. M?todo: Em um estudo longitudinal prospectivo, foram estudados 82 pacientes internados em uma unidade de terapia intensiva de um hospital universit?rio. Foram avaliadas as seguintes vari?veis: metas energ?tica e proteica da (TNE), os valores prescritos e administrados da (TNE), as causas e frequ?ncias das inadequa??es na infus?o da dieta, e os desfechos da terapia nutricional. O diagn?stico nutricional foi definido por meio de par?metros antropom?tricos, exames laboratoriais e instrumentos de rastreamento nutricional (nutric score e nutritional risk screening). Para a an?lise estat?stica foi utilizado o teste de Wilcoxon, o teste Qui-quadrado ou teste Exato de Fisher e o teste de Mann-Whitney. Resultados: A m?dia da meta energ?tica foi de 2.132,91 kcal e a proteica foi de 113,96 g por dia. A infus?o m?dia de energia foi de 53,44% da meta e de prote?na foi de 43,72% da meta, diferen?a estatisticamente significante para ambas as vari?veis (p<0,0001). Verificou-se diferen?a estatisticamente significante (p<0,0001) para todas as compara??es efetuadas entre a meta, prescri??o e infus?o da TNEE. Para a caloria, a prescri??o foi em m?dia 68% (p<0,0001) do valor da meta calculada, sendo infundido 53% (p<0,0001) do valor da meta energ?tica. Para a prote?na, a prescri??o foi em m?dia 58% (p<0,0001) do valor da meta, sendo infundido em m?dia 43% (p<0,0001) do valor da meta proteica. Foi infundido 72% do que foi prescrito tanto para caloria como para prote?na. Todos os pacientes avaliados apresentaram algum tipo de intercorr?ncia na infus?o e para 90% dos pacientes n?o houve justificativa para o atraso na infus?o. Cinquenta por cento (50%) dos pacientes em TNE apresentavam risco nutricional. Conclus?o: A TNE n?o supre totalmente as necessidades energ?ticas e proteicas dos pacientes cr?ticos. As complica??es que acometem o paciente grave interrompem a infus?o da dieta, bem como atrasos evit?veis. Tais achados refor?am a import?ncia do monitoramento adequado e cuidadoso da terapia nutricional enteral no paciente grave.

La diversité des maladies des patients de réanimation fait que l’environnement technologique de soins intensifs est composé de nombreux systèmes de monitorage de constantes physiologiques, permettant à l’équipe soignante de déterminer un traitement adapté au patient. De plus en plus de systèmes ont une fonction d’assistance à la prescription ou aux soins afin de réduire la charge de travail et mentale des infirmières exigées par certains traitements ou protocoles. Ces systèmes informatisés facilitent l’intégration du protocole et de l’information disponible dans les signaux et peuvent aboutir à des systèmes de complexité élevée. La question de l’évaluation de la qualité de la réalisation et de la balance bénéfice/risque pour les patients liée à l’usage de nouveaux systèmes d’assistance se pose alors. Un problème consiste à mener cette évaluation a priori dès la conception du protocole ou de l’algorithme. Ce travail de thèse donne un exemple de méthode pour un système d’assistance au contrôle de la glycémie des patients de réanimation : l’évaluation est menée depuis la conception de l’algorithme de contrôle jusqu’à une étude clinique de grande ampleur. L’origine du dispositif étudié vient de ce que les patients présentent souvent une hyperglycémie liée au stress à leur arrivée en réanimation (l’augmentation de l’insulino-résistance, l’administration de certaines de drogues ou la déficience en insuline inhibent la réponse physiologique à l’augmentation de la glycémie). Un problème vient alors de ce que, d’une part, l’hyperglycémie prolongée étant associée à une morbidité voire une mortalité accrue, contrôler la glycémie est bénéfique, et d’autre part réduire la glycémie fait courir le risque d’épisodes hypoglycémiques pendant le séjour en réanimation. Dans ce cas, optimiser la balance bénéfice/risque est encore un problème ouvert. Bien qu’il existe de nombreux travaux sur la modélisation de la pharmacodynamique du système glucose-insuline, peu de travaux exploitent ces modèles pour fournir un système de contrôle fonctionnel, testé et industrialisable. La thèse présente un système de contrôle glycémique ainsi qu’une méthode d’évaluation généralisable à d’autres systèmes, qui teste numériquement les performances techniques et cliniques de ce type de systèmes sur des patients virtuels. Les résultats d’une étude clinique réelle sont aussi présentés. / The variety of ICU patients diseases implies that technological environment of critical care is composed of many vital signs monitoring systems, allowing the medical team to determine appropriate treatment to the patient. More and more systems have a decision-making support function to reduce the mental and physical workload of nurses required for certain treatments or protocols. These computerized systems facilitate the integration of the protocol and the information available in the signals and can lead to systems of high complexity. The issue of assessing the performances and the benefit/risk balance for the patient related to the use of new support systems arises. The problem is to conduct this evaluation a priori, during the design process of the protocol or algorithm. This work provides an example of a method to support the control of blood glucose in the ICU system evaluation is conducted for the design of the control algorithm to a large-scale clinical study.The origin of the studied device comes from the fact that patients often experience hyperglycemia due to stress upon their arrival in the ICU (increased insulin resistance, administration of interacting drugs or insulin deficiency inhibit the physiological response to the blood sugar increase). A problem then is that, on the one hand, as sustained hyperglycemia is associated with an increased morbidity or mortality, controlling glycaemia reduces risks, but, on the other hand, reducing blood sugar exposes to the risk of hypoglycemia during the ICU stay. In this case, optimizing benefit/risk ratio is still an open problem.Although there are many studies on modeling the pharmacodynamics of glucose-insulin system, few works use these models to provide a functional, tested and industrialized control system. The thesis presents a glycemic control system and a generalized method of evaluation with other systems, which tests digitally technical and clinical performances of such systems on virtual patients. The results of a real clinical trial are also presented.
