No. of bitstreams: 1 André Gustavo Moura Guimarães.pdf: 1691381 bytes, checksum: b4f575802538a0af96f868e24171236c (MD5) Previous issue date: 2018-03-06 / Introduction: neonatal pain results in neurobiological effects, and changes in behavioral reactions of children who were born prematurely. There is no clear description about the pain caused by chest physiotherapy technique, nor about the possible non-pharmacological interventions to prevent it. Objective: to evaluate neonatal pain and physiological parameters during the chest physiotherapy in premature neonates (PTNB) in neonatal intensive care. Method: a randomized controlled trial, not blinded, in which 120 PTNB in mechanical ventilation were studied. They were randomized into four groups: control group (CG), diaphragmatic stimulation group (EDG), manual hyperinflation group (MHG), thoracic vibration group (VTG), containing 30 individuals in each one. The protocol consisted of 3 phases, the first phase being considered the control, and the other associated with non-pharmacological techniques to reduce pain: application of the technique (phase 1), application of technique + facilitated tucking (phase 2), application of technique + glucose (phase 3). Heart rate (HR), respiratory rate (RR), SpO2, Behavioral pain scale Indicators of Infant Pain (BIIP, ranges from 0 to 10) and Neonatal Infant Pain Scale (NIPS, ranges from 0 -7) were recorded at pre, during and after (15 minutes) the procedures described. Results: 62 (51.66%) RNPT were female, and most considered small for gestational age (83, 69%). Physiological variables (HR, FR, and SpO2) behaved in a similar manner in all groups (CG, MHG, EDG, VTG), being greater in phase 1, however these variables were reduced at phase 2 and 3 (p < 0.05). This means that during the application of non-pharmacological intervention (facilitated tucking or glucose) there was reduction of those variables. BIIP and NIPS scales showed increased in all of the groups in the phase 1 during the application of the techniques, however, similar to the physiological variables, these scales had reduced scores when applied to facilitated tucking (phase 2) or glucose (phase 3), p < 0.05. The number of individuals who have had pain assessed by BIIP (> 3 points) at the moment after in the phase 1 was 83 (69%), in phase 2 was 22 (18%), and in phase 3 of 34 (28%), p < 0.001. Conclusions: The chest physiotherapy techniques can increase the pain in PTNB, however, the non-pharmacological techniques, such as facilitated tucking and glucose, were able to reduce it. / Introdução: A dor neonatal desencadeia efeitos neurobiológicos agudamente, e alterações nas reações comportamentais da criança nascida prematuramente. Não há descrição clara sobre a dor ocasionada por técnicas manuais de fisioterapia respiratória, tampouco sobre as possíveis intervenções não farmacológicas na prevenção da mesma. Objetivo: Avaliar a dor neonatal e parâmetros fisiológicos durante a fisioterapia respiratória em neonatos prematuros na UTI neonatal. Metodologia: ensaio clínico randomizado controlado, não cego, no qual foram estudados 120 recém-nascidos prematuros (RNPT), de ambos os sexos, em ventilação mecânica. Foram randomizados em quatro grupos: grupo controle (GC), grupo estimulação diafragmática (GED), grupo hiperinsuflação manual (GHM), grupo vibração torácica (GVT), contendo 30 indivíduos em cada. O protocolo constou de 3 fases, sendo a primeira fase considerada a controle, e as demais associadas a técnicas não farmacológicas de redução da dor: aplicação da técnica (fase 1), aplicação da técnica e contenção (fase 2), aplicação da técnica e glicose (fase 3). A frequência cardíaca (FC), respiratória (FR), SpO2, escala de dor Behavioral Indicators of Infant Pain (BIIP, varia de 0 a 10) e Neonatal Infant Pain Scale (NIPS, varia de 0 -7) foram registradas pré, durante e após (15 minutos) dos procedimentos em cada fase descrita. Resultados: 62 (51,66%) dos RNPT do sexo feminino, e a maioria considerados pequenos para idade gestacional (83 69%). As variáveis fisiológicas (FC, FR, e SpO2) se comportaram de maneira semelhante, em todos os grupos, sendo maior na fase 1, reduzindo nas fases 2 e 3 (p<0,05). Durante a aplicação de intervenção não farmacológica (contenção ou glicose) houve redução daquelas variáveis. As escalas BIIP e NIPS mostraram aumento em todos dos grupos na fase 1 durante a aplicação das técnicas, sendo reduzida a dor quando aplicado a contenção (fase 2) ou a glicose (fase 3), p< 0,05. O número de indivíduos que tiveram dor avaliado pela BIIP (> 3 pontos) no momento após na fase 1 foi 83 (69%), na fase 2 foi 22 (18%), e na fase 3 de 34 (28%) p< 0,001. Conclusões: As técnicas de manuais de fisioterapia respiratória demonstraram gerar dor nos RNPT, entretanto, técnicas não farmacológicas como contenção e glicose foram capazes de reduzi-la.

Le pronostic à court terme des patients d'oncohématologie admis en réanimation s'est notablement amélioré au cours des deux dernières décennies. Ces progrès sont le fait d'une diversification importante de l'arsenal thérapeutique relatif à l'oncologie et l'hématologie mais aussi d'une meilleure prise en charge de ces patients au sein des réanimations. Notre travail de recherche s'est centré sur la devenir de ces malades et les facteurs associés à celui-ci.Dans ce cadre, nous avons conduit plusieurs études observationnelles pronostiques portant sur des patients neutropéniques admis en réanimation. Nous avons montré que les facteurs indépendamment associés à la mortalité hospitalière étaient une allogreffe de moelle, le recours à la ventilation mécanique invasive, le recours à l'épuration extra-rénale ainsi qu'une documentation microbiologique positive. De plus, chez les patients neutropéniques admis en réanimation pour sepsis sévère/choc septique, les facteurs indépendamment associés à la mortalité en réanimation étaient une antibiothérapie initiale inappropriée, un délai d'initiation de l'antibiothérapie en réanimation > 1h, une documentation microbiologique positive à bacille gram négatif non fermentant et à un score SOFA élevé dès l'admission en réanimation. La désescalade du traitement antibiotique initial, réalisable dans 44% des cas,était sans répercussion significative sur le pronostic à court et long-terme. Enfin, chez les patients neutropéniques admis en réanimation pour détresse respiratoire aiguë, le seul facteur indépendant associé à la mortalité hospitalière était le recours à la ventilation mécanique alors que l'utilisation de corticostéroïdes les jours précédant l'admission en réanimation et l'une admission dans un contexte de sortie d'aplasie étaient protecteurs.Finalement, nous avons montré dans une récente revue de la littérature que le pronostic du patient d'oncohématologie admis en réanimation s'était amélioré au cours du temps et que la neutropénie ne semblait pas être un facteur pronostique dans ce contexte.En conclusion, nous avons montré que le patient neutropénique est à haut risque de complications sévères infectieuses, respiratoires et immunologiques. Ces complications impactent le pronostic des patients de manière significative. Nos résultats vont donner lieu à plusieurs essais randomisés chez le patient neutropénique admis en réanimation notamment autour de la désescalade antibiotique au cours du sepsis et des stratégies d'oxygénothérapie en cas de détresse respiratoire. / The short-term prognosis of patients with onco-hematological diseases and neutropenia admitted to intensive care has significantly improved over the last two decades. This progress is the fact of a significant diversification of the armamentarium on oncology and hematology but also a better management of these patients in the ICUs. Our research has focused on the outcome of these patients and its prognostic factors. In this context, we have conducted several prognostic observational studies of neutropenic patients admitted to intensive care units. We showed that factors independently associated with hospital mortality were the bone marrow transplantation, the use of invasive mechanical ventilation, the use of renal replacement therapy and a positive microbiological documentation. Moreover, in neutropenic patients admitted to intensive care for severe sepsis / septic shock, factors independently associated with ICU mortality were inappropriate initial antibiotic therapy, a delay of antibiotic treatment > 1h, a positive microbiological documentation with non-fermenting gram negative bacilli, a high SOFA score on admission in ICU. The de-escalation of initial antibiotic treatment feasible in 44% of cases had no significant impact on the short and long-term outcomes. Otherwise, in neutropenic patients admitted to intensive care for acute respiratory failure, the only independent factor associated with hospital mortality was the need for mechanical ventilation, while the use of corticosteroids in the days before ICU admission and a admission during neutropenia recovery period were protective. Finally, we have shown in a recent review of the literature that the outcome of hematology-oncology patient admitted to intensive care had improved over time and that neutropenia did not seem to be a prognostic factor in this context. In conclusion, we have shown that the neutropenic patient is at high risk of severe infectious,respiratory and immunological complications. These complications significantly impact the outcome of these patients. Our results could lead to the planning of several randomized trials in neutropenic patients admitted to intensive care in particular about the escalation antibiotic in sepsis and oxygentherapy strategies for respiratory distress.

This review will focus on the therapeutic uses of antioxidant liposomes. Antioxidant liposomes have a unique ability to deliver both lipid- and water-soluble antioxidants to tissues. This review will detail the varieties of antioxidants which have been incorporated into liposomes, their modes of administration, and the clinical conditions in which antioxidant liposomes could play an important therapeutic role. Antioxidant liposomes should be particularly useful for treating diseases or conditions in which oxidative stress plays a significant pathophysiological role because this technology has been shown to suppress oxidative stress. These diseases and conditions include cancer, trauma, irradiation, retinotherapy or prematurity, respiratory distress syndrome, chemical weapon exposure, and pulmonary infections.

Acute respiratory distress syndrome (ARDS) is in the center of the scientific debate both for its complex pathophysiology and for the discussion about the remedies that could contribute to its healing. The intricate interplay of different body systems that characterizes ARDS is mirrored by two main research threads, one centered on the pathophysiological mechanisms of the disease and the other on the new approaches to lung imaging. In this Special Issue of the Journal of Clinical Medicine are presented studies using imaging technologies based on electrical impedance tomography, synchrotron radiation computed tomography and intravital probe-based confocal laser endomicroscopy. The studies on the pathophysiological mechanisms pertain to the evaluation of the biomarkers of the disease and the platelet disfunction during extracorporeal membrane oxygenation. These contributions witness the intensity of ARDS research as many of the key problems of the disease are only in part resolved.

Enteral nutrition (EN) is often delayed in critically ill patients despite strong evidence to support that early enteral nutrition feeding is beneficial in this population. Adverse outcomes in critically ill patients in which nutrition is delayed include a longer length of stay and time on the ventilator, and a higher incidence of pneumonia and hospital mortality. The purpose of this literature review was to evaluate the current evidence regarding trophic enteral feeds in mechanically ventilated adult patients with acute respiratory distress syndrome (ARDS)/acute lung injury (ALI) and associated clinical outcomes. A retrospective literature review was performed to identify articles published on the topic of trophic feeds in mechanically ventilated adult patients with ALI/ARDS, with a focus on associated clinical outcomes. The studies included in this literature review indicated that the dose and timing of enteral nutrition in critically ill patients with ARDS/ALI had an effect on clinical outcomes. It is possible that additional variables such as the level of organ dysfunction and varying definitions for trophic enteral nutrition also influenced clinical outcomes. The United States (U.S.) and Canadian guidelines for nutrition supportrecommend either trophic or full EN for patients with ARDS/ALI on the basis that these two feeding strategies have similar patient outcomes over the first week of hospitalization. After reviewing the literature, we conclude that caution is warranted when following this recommendation. Regressions suggest full calorie enteral nutrition administered early in the course of critical illness significantly increased the odds of mortality, whereas full calorie enteral nutrition administered later reduced the odds of mortality.
