The incidence of NEC is inversely proportional to gestational age and birth weight, reaching 12% of children weighing less than 1500g and triggering death in 30% of casos.Tem up to analyze the occurrence of ECN and associated factors its development in newborns (NB) with low weight. It is an epidemiological case-control study, conducted from March 1, 2014 to June 30, 2015, in two NICUs in Sao Luis, MA. The sample size was calculated considering a case to three controls (1:3), establishing confidence level of 95% and power of 80% study, sufficient to detect an OR = 2.5, making 236 newborns (RN) underweight, and 59 infants with NEC diagnoses (case group) and 177 infants without NEC (control group). In analyzing the data maternal variables (gestational period and the type of delivery) and newborn (birth and hospitalization) were organized in six blocks, arranged in a hierarchical structure, and analyzed in STATA 11.0 program. The differences between means were assessed by Student's t-test, whereas the differences between the medians by Man Whitney test. It was considered as the dependent variable, the ECN, and as independent, maternal and neonatal variables. Univariate analysis was performed between independent variables of two groups: case and control, estimated the OR values, with reference category OR = 1, built the confidence intervals of 95% and certain values of p. In the hierarchical analysis was carried out by the group of variables in levels according to influence the outcome. Of the 59 cases of NEC, 61.02% were female, with a median of 45 days hospital stay; and 177 controls without ECN, 54.55% were male, with a median hospital stay of 19.5 days. As for the clinical outcome of cases of NEC, 40.68% progressed to death. At the end of hierarchical analysis remained statistically significant association, the use of antenatal corticosteroids (OR = 2.90; p <0.001), reduced amniotic fluid (OR = 2.03;p<0.001), resuscitation at birth (OR = 1, 35, p = 0.010), birth weight ≤1500g (OR = 3.32, p <0.001), transfusions (OR = 2.11, p = 0.040) and the use of surfactant (OR = 2.41, p = 0.020). It concludes that maternal aspects related to pregnancy and neonatal concerning the birth and hospitalization may be influencing the appearance of NEC. / A Enterocolite Necrosante(ECN) é uma grave enfermidade gastrintestinal, de causa multifatorial e está entre as principais causas de mortalidade neonatal no ambiente da Unidade de Terapia Intensiva Neonatal (UTIN). A incidência da ECN é inversamente proporcional à idade gestacional e o peso de nascimento, atingindo 12% das crianças com peso inferior a 1500g e desencadeando o óbito em 30% dos casos.Tem-se como objetivo analisar a ocorrência de ECN e os fatores associados ao seu desenvolvimento em recém-nascidos (RN)de baixo peso. Trata-se de um estudo epidemiológico tipo caso controle, realizado no período de 01 de março de 2014 a 30 de junho de 2015, em duas UTINs de São Luís-MA. O tamanho da amostra foi calculado considerando um caso para três controles (1:3), estabelecendo nível de confiança de 95% e poder do estudo de 80%,suficiente para detectar um OR=2,5, perfazendo 236 recém-nascidos (RN) de baixo peso, sendo 59 RN com diagnósticos de ECN (grupo caso) e 177 RN sem ECN (grupo controle). Na análise dos dados as variáveis maternas (período gestacional e o tipo de parto) e neonatais (nascimento e hospitalização) foram organizadas em seis blocos e dispostas em uma estrutura hierarquizada, e analisadas no programa STATA 11.0. As diferenças entre as médias foram avaliadas pelo teste T-Student, enquanto que as diferenças entre as medianas pelo teste de Man Whitney. Considerou-se como variável resposta, a ECN, e como independentes, as variáveis maternas e neonatais. Foi realizada análise univariada entre as variáveis independentes dos doisgrupos: caso e controle, estimados os valores das OR, tendo como categoria de referência OR=1, construídos os intervalos de confiança de 95% e determinados os valores de p. Na análise hierarquizada foi realizadoo agrupamento das variáveis em níveis segundo a influência no desfecho. Dos 59 casos de ECN, 61,02% eram do sexo feminino,com mediana do tempo de hospitalização de 45 dias; edos 177 controles sem ECN, 54,55% eram do sexo masculino, com mediana do tempo de hospitalização de 19,5 dias. Quanto ao desfecho clínico dos casos de ECN, 40,68% evoluíram a óbito. Ao final da análise hierarquizada mantiveram associação estatisticamente significante, o uso de corticóide antenatal (OR=2,90; p<0,001), líquido amniótico reduzido (OR=2,03;p<0,001), reanimação ao nascimento (OR=1,35; p=0,010), peso ao nascimento ≤1500g (OR=3,32;p<0,001), transfusão (OR=2,11;p=0,040) e uso de surfactante (OR=2,41;p=0,020). Conclui-se que os aspectos maternos relacionados ao período gestacional e os neonatais referentes ao nascimento e hospitalização podem estarinfluenciando no aparecimento da ECN.

Ao se considerar a importância da busca de indicadores que determinam, tanto a alta dos pacientes das unidades de terapia intensiva (UTIs) como o risco de óbito e readmissão dos internados nessa unidade, este estudo teve como objetivos: caracterizar os pacientes internados em UTIs de hospitais que tenham unidades intermediárias quanto aos dados demográficos e clínicos; descrever a mortalidade e a unidade de destino após a alta da UTI e a freqüência de readmissão nessas unidades; comparar as médias do Nursing Activities Score (NAS), Simplified Acute Physiology (SAPS II) e Logistic Organ Dysfunction (LODS) no primeiro e último dia de internação na UTI; identificar os fatores associados com a alta, óbito e readmissão dos pacientes em UTI na mesma internação hospitalar. Trata-se de um estudo prospectivo longitudinal de pacientes adultos internados em UTIs gerais de dois hospitais governamentais e dois não governamentais do Município de São Paulo que possuíam unidades intermediárias. A casuística compôs-se de 500 pacientes adultos admitidos nessas UTIs. Os dados coletados foram referentes as primeiras e últimas 24 horas de permanência na UTI, porém os pacientes foram acompanhados até a alta hospitalar para identificação das readmissões. Os resultados mostraram predomínio de indivíduos idosos (55,80%), do sexo feminino (56,60%), a maior parte procedente do Pronto-Socorro/Atendimento (37,60%) e tempo de permanência na UTI entre um e dois dias (36,60%). Os antecedentes e os motivos de internação mais freqüentes foram relacionados às doenças do aparelho circulatório. As médias dos escores, no primeiro dia de internação na UTI, foram SAPS II, 37,41, LODS, 4,32 e NAS, 62,13. No último dia de internação, o valor médio do SAPS II foi de 36,15, do LODS, 4,2 e do NAS, 52,17. Os pacientes com alta da UTI apresentaram no último dia de internação, a média desses escores inferior à de admissão. Nos indivíduos que morreram, as médias dos escores SAPS II e LODS foram superiores no último dia de internação na UTI em relação aos valores de admissão; já as médias do NAS foram similares. Os pacientes readmitidos apresentaram na alta da UTI diminuição da média dos escores, porém essa diferença só alcançou níveis significativos quando o NAS foi o indicador utilizado. A mortalidade foi 20,60% durante a internação na UTI, a maioria dos pacientes foi transferida para unidade intermediária e aproximadamente, 9% foram readmitidos. Os pacientes que foram encaminhados à unidade intermediária diferiram dos que foram para unidade de internação em relação à idade, procedência, antecedentes, motivo de internação, SAPS II na admissão e NAS na admissão e alta. Os pacientes que morreram, apresentaram maior tempo de internação, escores de gravidade mais altos na admissão e, imediatamente, antes do óbito. No último dia de internação na UTI, o NAS foi mais elevado entre os que morreram. Para o grupo de readmitidos, somente antecedentes relacionados a doenças infecciosas e parasitárias, doenças do aparelho geniturinário e o LODS na admissão foram diferentes se comparados aos não readmitidos / Considering the relevance of collecting indicators to define either the discharge of patients from the Intensive Care Units (ICUs) or risk of death and readmission of interned patients into these units, this study had as objectives: - to characterize the patients interned in ICUs in hospitals with intermediate care units according to demographical and clinical data; - to describe mortality, unit of destination after ICU discharge and frequency of readmission into these units - to compare the averages of the Nursing Activities Score (NAS), Simplified Acute Physiology (SAPS II) and Logistic Organ Dysfunction (LODS) during the first and the last day of internment in the ICU; - to identify the factors associated with the discharge, death and readmission of patients into the ICU, during the same hospital internment. This is a longitudinal prospective study of adult patients interned in general ICUs of two public hospitals and two private hospitals of the City of São Paulo, which had intermediate care units. The casuistry was composed of 500 adult patients who were interned in these ICUs. The collected data referred to the first and the last 24 hours spent in the ICU, however, a follow-up of the patients was made until their discharge in order to identify readmissions. The results show a predominance of elderly individuals (55.8%), of female gender (56.6%), with the larger number coming from the Emergency Room (37.6%) and patients who spent between one and two days in the ICU (36.6%). The previous problems and the main motives for internment were related to circulatory system diseases. The average scores during the first day in the ICU were SAPS II (37.41), LODS (4.32) and NAS (62.13%). During the last day of internment, the average scores were SAPS II (36.15), LODS (4.2), and NAS (52.17%). Patients who had been discharged from the ICU presented, during the last day of internment, an average in these scores inferior to those registered on their entry day. For the individuals who died, the average SAPS II and LODS scores were superior to those of the entry day in the ICU, nevertheless, the NAS averages were similar. The readmitted patients had, at the time of discharge from the ICU, less than average scores in SAPS II, LODS and NAS. This difference, however, only reached significant levels when the NAS indicator was applied. The death rate was 20.6% during the ICU internment, the majority of the patients were transferred to an intermediate care unit and approximately 9% were readmitted. Patients, who were transferred to the intermediate care unit, differed from those who went to a general nursing unit according to age, origin, antecedents, motive for internment, SAPS II during their entry, NAS during their entry and discharge. Patients who died presented longer internment time and had more severe scores at their entry into the ICU and immediately before death. The NAS during the last internment day in the ICU was higher for those who died. For the readmitted group, only antecedents related to contagious and parasitic diseases, genitourinary system diseases, and LODS at entry were different when compared to those of patients who were not readmitted into the ICU

Introdução: A unidade de terapia intensiva (UTI) é conhecida por ser um setor de alta complexidade dos pacientes e por seu alto custo ao sistema hospitalar. A gravidade da doença, o tempo de internação na UTI e a necessidade de ventilação mecânica invasiva (VMI) são fatores conhecidos como influenciadores no custo destas unidades, sendo que aproximadamente 30% dos pacientes internados em UTI necessitam de VMI. Os objetivos deste estudo foram avaliar os custos de internação em UTI comparando unidades com assistência de fisioterapia 24 horas e unidades com assistência de fisioterapia 12 horas e analisar o impacto da fisioterapia nos referidos custos. Método: Este é um estudo observacional, prospectivo, realizado em um hospital geral, público e de grande porte, localizado na cidade de São Paulo. Foram incluídos pacientes clínicos e cirúrgicos com 18 anos de idade ou mais, que estiveram em VMI por um período >= 24 horas e que receberam alta da UTI para a enfermaria. A coleta de dados incluiu diagnóstico de internação hospitalar, diagnóstico de admissão na UTI, gravidade do paciente no momento da admissão na UTI através do Acute Physiology and Chronic Health Disease Classification (APACHE II), tempo de VMI e tempo de internação na UTI; para a análise de custos utilizamos a ferramenta Omega French Score. Um modelo de regressão linear múltipla foi construído para verificar a associação entre o custo de internação em UTI com o turno diário de assistência fisioterapêutica. Resultados: Foram incluídos na amostra 815 pacientes, distribuídos em dois grupos conforme o turno de fisioterapia existente na UTI: 332 pacientes em UTI\'s com 24 horas de assistência fisioterapêutica (PT-24) e 483 pacientes em UTI\'s com 12 horas de assistência fisioterapêutica (PT-12). Os grupos não apresentaram diferença quanto ao APACHE II (p=0,65); comparado ao grupo PT-12 o grupo PT-24 era mais velho (p < 0,001), apresentou menor tempo de VMI (p < 0,001) e de internação na UTI (p=0,013). Quanto a análise de custos o grupo PT-24 apresentou custos menores indicados pela menor pontuação no Omega 3 (p=0,005) e Omega Total (p=0,010), menor custo direto, custo com equipe médica e enfermagem (p=0,010). A análise de regressão linear múltipla indicou associação do custo da internação em UTI com as variáveis APACHE II (p < 0,001), tempo de internação da UTI (p < 0,001) e assistência fisioterapêutica em turnos de 24 horas (p=0,05). Conclusão: O grupo com assistência de fisioterapia em turnos de 24 horas apresentou custos menores sendo que a severidade da doença, o tempo de internação na UTI e a assistência de fisioterapia foram variáveis preditoras para redução de custo de internação na UTI / Background: Intensive care unit (ICU) is considered a complex and expensive hospital department. The severity of illness, the length of ICU stay and the need for invasive mechanical ventilation (IMV) are known as influencing factors of costs to these units and approximately 30% of patients admitted at ICU will need IMV. Our aim is to address the costs related to ICU stay by comparing units with the provision of a daily 24-hour physiotherapy shift to a regular 12-hour PT shift and to analyze the impact of physical therapy in ICU costs. Method: This is a prospective, observational study, carried out in a general, public and large hospital, located in the city of São Paulo. Were included in the sample clinical and surgical patients, aged >=18 years old, invasive mechanically ventilated (IMV) >= 24 hours and discharged to ward were included. Data collection included reason of hospital admission and reason of ICU admission; Acute Physiology and Chronic Health Disease Classification System II (APACHE II); IMV duration; ICU-LOS; for cost analysis we use the Omega French Score. A multiple linear regression model was constructed to verify the association between costs of ICU stay and daily shift of physiotherapy. Results: 815 patients were included, distributed into two groups: 332 patients at ICUs with 24-hour physiotherapy shift (PT-24) and 483 patients in ICUs with 12-hour physiotherapy shift (PT-12). There was no statistical difference between the groups regarding the APACHE II (p=0,65); the PT-24 group was older (p < 0,001), and featured better clinical outcome when compared to the PT-12 group with shorter IMV (p < 0,001) and duration of stay in the ICU (p=0,013). About cost analysis the PT-24 group showed lower scores on Omega 3 (p=0,005) and Omega (p=0,010), lower direct cost, cost of medical and nursing staff (p=0,010). Multiple linear regression reveal that costs of ICU hospitalization to be associated to APACHE II (p < 0,001), length of ICU stay (p < 0,001) and 24-hour physiotherapy assistance (p=0,05). Conclusion: Patients in the group with the assistance of physiotherapy in 24-hour shifts presented decreased total and staff costs, physiotherapy assistance were considered predictor for cost reduction.

O objetivo do presente trabalho foi identificar a frequência de inadequação entre a quantidade de Terapia Nutricional Enteral (TNE) prescrita e aquela recebida por pacientes internados em hospital geral, e estudar as condições associadas que podem levar a essa inadequação. Adultos hospitalizados (201), que receberam exclusivamente TNE, foram acompanhados por até 21 dias por equipe de especialistas em Terapia Nutricional, que registrou o processo em fichas específicas. Todos os doentes receberam fórmulas enterais industrializadas por sondas enterais ou nasoenterais, gastrostomias ou jejunostomias em sistema aberto. As causas de discordância entre prescrição e recebimento de NE não foram mutuamente excludentes. A análise estatística foi feita através de regressão logística pelo modelo de Cox. Dos 152 pacientes considerados na análise, 36 (23,5%) ficaram internados em enfermarias e 116 (76,5%) em UTI. Oitenta por cento dos pacientes receberam mais de 80% das necessidades energéticas diárias, a partir do quarto dia do acompanhamento. Existe inadequação entre a quantidade de TNE prescrita e aquela recebida em 20% dos pacientes. As causas de não recebimento de NE foram: atraso na administração de TNE (3,1%), distensão abdominal (5,6%), recusa do paciente (6,8%), obstrução de acesso enteral (8,6%), vômitos (10,5%), diarreia (17,9%), causa desconhecida (17,9%), suspensão de TNE por interferência de profissional não integrante da equipe especializada em TN (25,9%), perda acidental de acesso enteral (34%), estase gástrica (34%) e problemas logísticos (99,4%). A análise univariada apontou associação entre o grupo de pacientes que recebeu menos que 60% da energia prescrita e suspensão de TNE por interferência de profissional não integrante da equipe especializada em TN (p=0,016). Houve associação linear (p=0,025) entre o tipo de leito hospitalar e percentual de adequação no recebimento de dieta quanto maior a adequação entre prescrição e recebimento de dieta, menor foi o número de pacientes em UTI. A regressão logística apontou que pacientes com doenças neurológicas têm maior chance de receber mais que 80% da dieta prescrita que pacientes com doenças cardiológicas (OR=3,75; p<0,01). Pacientes com doenças cardiológicas e pacientes em UTIs estão mais sujeitos a receber menos que o total de NE prescrita / We investigated factors leading to a reduction in enteral nutrition (EN) prescribed by a nutritional support team (NST) at a general hospital in Brazil. In this prospective, observational study, hospitalized adults receiving only EN therapy via tube feeding were followed for up to 21 days between July and October 2008. The 152 subjects analyzed included 36 (23.5%) ward patients and 116 (76.5%) intensive care unit (ICU) patients. Eighty percent of the targeted feeding volume was achieved on day 4 by 80% of the patients. Inadequacy between prescription and intake of EN was 20%. Reasons for not receiving the total amount of EN prescribed included delay in the EN administration (3.1%), abdominal distention (5.6%), patient refusal to treatment (6.8%), feeding tube obstruction (8.6%), vomiting (10.5%), diarrhea (17.9%), unknown causes (17.9%), interference by a non-NST physician (25.9%), accidental feeding tube loss (34%), presence of high gastric residual (34%), and operational logistics at the hospitals Nutrition and Dietetics Service (99.4%). There was a significant association between patients who received less than 60% of the prescribed EN and external physician interference (p=0.016). Patients in ICU also received inadequate EN (p=0.025). Neurologic patients had a greater chance of receiving more than 80% of the prescribed EN amount than cardiac patients (Odds Ratio=3.75, p<0.01). Cardiologic patients and ICU patients are at a higher risk of inadequacy between prescription and intake of EN

Les patients de réanimation sont des patients à très haut risque de survenue de candidoses invasives associées à une importante mortalité. Les espèces du genre Candida sont retrouvées en troisième position des agents infectieux les plus fréquemment isolés au cours des septicémies. Le diagnostic reste difficile en raison d’une clinique aspécifique et d’une sensibilité médiocre des hémocultures. Des scores prédictifs, des biomarqueurs ou encore des PCR ont été développés de manière à améliorer le diagnostic et l’identification des patients à risque. Dans ce travail, la première partie présente les données de l’évolution de l’écologie fongique, des candidoses invasives, des prescriptions d’antifongiques et des sensibilités aux antifongiques sur une période de dix ans dans un service de réanimation. Au cours de cette période, les changements observés dans la prescription d’antifongiques n’ont pas entrainé de modifications significatives de l’écologie fongique ni d’apparition de résistances. Dans une deuxième partie, nous présentons les résultats d’une étude prospective observationnelle bicentrique réalisée chez 435 patients non neutropéniques de réanimation. L’analyse de plusieurs variables (facteurs de risque de candidose invasive, colonisation à Candida sp., dosages d’antigène mannane et d’anticorps anti-mannane) a permis l’élaboration d’un score prédictif de survenue de candidose invasive. Finalement, la dernière partie du travail présente la mise au point de PCR Candida en temps réel dans le sang ainsi qu’une évaluation de la technologie de digital PCR. / Patients in intensive care units (ICU) are at very high risk of invasive candidiasis associated with high mortality rate. Candida species are the third cause of septicemia. Clinical signs lack of specificity and blood cultures lack of sensitivity, and therefore the diagnosis remains a challenge. In order to improve the identification of patients with invasive candidiasis, predictive rules, biomarkers and PCR have been developed. The first part of this work describes the evolution over a ten years period in one ICU in Candida species distribution, susceptibility to antifungal drugs and consumption of antifungal agents. Changes in antifungal drug consumption were observed but they were not associated with significant changes in fungal ecology or with the emergence of resistant species. In a second part, we present a prospective, observational and bicentric study performed in 435 non-neutropenic patients in ICU. Several variables (risk factors of invasive candidiasis, Candida colonization, mannan antigen and anti-mannan antibodies) were analyzed and a predictive score of invasive candidiasis has been developed. Finally, the last part presents the development of Candida real-time PCR in blood, as well as the evaluation of a digital PCR.

Bakgrund: 100 000 vårdskador uppstår i Sverige varje år. Patienter som vårdas på intensivvårdsavdelningar löper störst risk att drabbas. För att minska riskerna och höja patientsäkerheten krävs kunskap om vilka risker som finns och vilka misstag som begås. Syfte: att beskriva i vilka sammanhang intensivvårdssjuksköterskor upplever att patientsäkerheten brister. Metod: en empirisk studie med kvalitativ design har utförts. Datainsamlingen har skett i två fokusgrupper med intensivvårdssjuksköterskor. Materialet analyserades och presenteras i form av teman och kategorier. Resultat: brister sågs i organisationen och sjuksköterskorna. Sjuksköterskorna upplevde även att brister i samarbetet och kommunikationen uppstod mellan individer samt mellan individer och organisationen. Slutsats: organisationen måste bistå med patientsäkra lokaler och lyfta patientsäkerheten på avdelningen. Sjuksköterskorna i sin tur måste följa författningar och lokala rutiner. Detta för att skydda patienter och för att inte själva straffas för vårdskador. Organisationen och sjuksköterskorna måste därtill tillsammans förbättra samarbetet och kommunikationen dem emellan. Klinisk betydelse: studien kan användas i ett förbättringsarbete på den undersökta avdelningen samt stärka gruppsamhörigheten för intensivvårdssjuksköterskorna. / Background: 100 000 adverse events occur annually in Swedish hospitals. Patients being treated in intensive care units are most at risk. To reduce risks and improve patient safety requires knowledge of the risks involved and the mistakes made. Aim: to describe in which context intensive care nurses experience that patient safety fails. Method: an empirical study with a qualitative design has been made. Data has been collected in two focus groups with intensive care nurses. The material was analyzed and presented in terms of themes and categories. Results: patient safety deficiencies were found in the organization and among the nurses. The nurses also described deficiencies in the cooperation and communication between individuals and between individuals and the organization. Conclusion: the organization must give priority to patient safety issues and provide facilities well adapted to carry out safe care. As for the nurses, they must follow regulations and local procedures in order to prevent harm to patients and to avoid being punished for adverse events. The organization and the nurses must together improve cooperation and communication to promote patient safety. Clinical importance: this study can be used to improve patient safety at the investigated intensive care unit and strengthen the group cohesion among the critical care nurses.

Införandet av en mobil intensivvårdsgrupp (MIG) har visat sig ha goda resultat utomlands med minskade andningsstopp och mortalitet inom pediatrisk vård. Vid Astrid Lindgrens Barnsjukhus i Solna, Sverige (ALB) finns långt framskridna planer på att starta en MIG-verksamhet. Syftet med denna studie var att beskriva pediatriska patienter som faller in under potentiella MIG-kriterier innan inläggning på barnintensivvårdsavdelningen/barnintermediäravdelningen (BIVA/BIMA) på ALB. Studien gjordes retrospektivt genom journalgranskning av inskrivna pediatriska patienter på BIVA/BIMA under 2009. Totalt inkluderades 148 pediatriska patienter i åldern 0-18 år i studien. Resultat visade att Andningsbesvär var den vanligaste inskrivningsorsaken och att Andning var den vanligast förekommande kontaktorsaken. Provtagning var den mest förekommande åtgärden som utfördes på akutmottagningen/vårdavdelningen innan förflyttning till BIVA/BIMA. Slutsatsen blev att det skulle kunna finnas cirka 300 pediatriska patienter per år på ALB som skulle kunna vara aktuella för MIG-uppdrag. Det är en klar indikation för att starta en MIG-verksamhet på ALB för att minska inläggningar på BIVA/BIMA samt identifiera dessa pediatriska patienter i ett tidigt skede innan akut försämring. / The implementation of Pediatric Medical Emergency Team (PMET) has proven to reduce respiratory arrest and mortality in Pediatric hospitals worldwide. At Astrid Lindgrens Barnsjukhus in Solna, Sweden (ALB) there are advanced plans to start a PMET. The aim of this study was to describe pediatric patients that met potential PMET-criteria before being admitted to pediatric intensive care unit/high demand unit (PICU/HDU) at ALB. The study was a retrospective chart review of admitted pediatric patients at PICU/HDU during 2009. Totally 148 pediatric patients between the age of 0 to 18 years were included in the study. The result showed that respiratory problems were the most common reason for being admitted to the hospital and problems with breathing was the most frequent PMET-criteria. Before the patient moved to the PICU/HDU the most common intervention performed in the emergency department/wards was sample-taking. The conclusion was that around 300 pediatric patients a year could benefit from a PMET at ALB. That is a clear indication that a PMET should be started at ALB to reduce admitted patients to PICU/HDU and identify the patients at risk for acute worsening.

Mötet med närstående till patienter som avlidit är ett stressfyllt möte, både för närstående och sjuksköterskan. Tidigare forskning visade att närstående önskade få tydlig information och söker trygghet hos varandra. Närstående upplevde sjuksköterskan som en stor källa för trygghet och stöd i sorgprocessen. Den professionalitet och säkerhet hon förmedlar var av stor vikt för närståendes upplevelse av hela vårdtiden. Syftet med studien var att beskriva erfarna intensivvårdssjuksköterskors reflektioner från möten med närstående till patienter som avlidit. En intervjustudie med kvalitativ ansats gjordes. Informanterna i denna studie kunde alla klassificeras som skickliga och expertsjuksköterskor enligt Benners utvecklingsstadier för sjuksköterskan. Informanterna beskrev möten som kunde delas in i följande huvudteman för att ge stöd till de närstående som, trygghet, lyhördhet, stillhet och lugn. Med hjälp av dessa huvudteman upplevde informanterna att de kunde skapa optimala förutsättningar för att skapa stillhet och lugn. / Meeting patient’s next of kin after decease is a stressful meeting for both the next of kin and the advanced practice nurse. Preceding research showed that the next of kin sought to receive information that was easy to understand and that they seek solace from each other. The advanced practice nurse was experienced as a great source of comfort and support in the grieving process by next of kin. Professionalism and support mediated by the advanced practice nurse was of great importance for the next of kin’s experience of the hospitalization period. The aim of this study was to describe experienced intensive care unit nurses reflections of meeting next of kin to patients who are diseased. An interview study with a qualitative approach was done. The informants in this study could all be classified as the skilful and the expert nurse according to Benners stages of progression for the nurse. The informants described main themes to support and comfort the next of kin, they were; feeling secure, attentiveness, stillness. With the aid of these categories the informants experienced that they could create the optimal conditions in creating stillness in the storm that the next of kin are in after death has occurred.

L’aérosolthérapie est une pratique ancienne de plusieurs siècles. Progressivement l’administration inhalée de bronchodilatateurs et de corticoïdes s’est imposé comme le traitement au long cours de référence des maladies pulmonaires obstructives. Plus récemment de nouvelles molécules, comme les antibiotiques ou les mucomodulateurs, ont été administrées avec succès par voie inhalée, particulièrement chez les patients atteints de mucoviscidose. Alors que ces succès de l’aérosolthérapie ont été obtenus chez les patients en ventilation spontanée et traités essentiellement dans le contexte ambulatoire, les données sont beaucoup plus parcellaires concernant l’aérosolthérapie chez les patients admis en réanimation et plus particulièrement ceux soumis à la ventilation artificielle. Néanmoins, l’effet physiologique des bronchodilatateurs et des corticoïdes a été documenté chez les patients soumis à la ventilation artificielle et plusieurs études expérimentales et de recherche clinique [ont] documenté la faisabilité de l’antibiothérapie inhalée chez ces patients. Cinq travaux ont été réalisés dans le cadre de la thèse, faisant appel à des méthodes de recherche expérimentale sur banc, d’expérimentation animale, de recherche clinique et épidémiologique concernant l’aérosolthérapie en réanimation. Les deux premiers travaux ont consisté en une enquête internationale par voie électronique auprès des huit cents médecins exerçant en réanimation et d’une étude prospective observationnelle durant deux semaines dans quatre-vingts services de réanimation. Les résultats principaux de ces travaux sont que l’aérosolthérapie était très fréquente en réanimation et concernait près d’un quart des patients. Les molécules administrées étaient essentiellement des bronchodilatateurs et des corticoïdes, mais l’antibiothérapie inhalée était également pratiquée. […] L’aérosolthérapie est apparue comme bien tolérée à court terme […]. Le troisième travail a consisté en une évaluation sur banc des systèmes de nébulisation pneumatique synchronisée intégrés dans quatre ventilateurs de réanimation. Les résultats principaux de ce travail sont que ces systèmes permettaient un bon contrôle du volume courant délivré au patient durant la nébulisation ; en revanche la synchronisation inspiratoire n’était pas optimale […]. Le quatrième travail a consisté en une étude clinique évaluant la pharmacocinétique sérique de l’amikacine après son administration inhalée à forte dose chez vingt-deux patients soumis à la ventilation artificielle et atteints de pneumonie nosocomiale. L’administration était réalisée à l’aide d’un système de nébulisation pneumatique innovant, adapté à la ventilation artificielle. Le résultat principal de ce travail a été que la nébulisation de 60 mg/Kg d’amikacine s’est avéré faisable chez le patient sous ventilation artificelle et que les concentrations sériques observées étaient inférieures à celles observées après perfusion intraveineuse. […] Enfin, le dernier travail a consisté en une étude animale comparant la pharmacocinétique sérique de l’amikacine après administration intraveineuse, nébulisation et aérosolisation in situ à l’extrémité de la sonde d’intubation de porcelets soumis à la ventilation artificielle avec des poumons non infectés. Le principal résultat est que l’aérosolisation in situ a permis d’administrer de grandes quantitiés d’amikacine en très peu de temps. Néanmoins, les concentrations intra-parenchymateuses étaient très hétérogènes après aérosolisation in situ et fréquemment faibles […]. / Aerosoltherapy is a centuries-old practice. Inhaled bronchodilatators and corticosteroids have become the long-term treatment of choice for obstructive lung diseases. More recently, new molecules, such as antibiotics or mucus modulators have been successfully administrated by inhalation, particularly in patients with cystic fibrosis. While the success of aerosoltherapy were obtained in patients breathing spontaneously and essentially treated in the outpatient setting, data are much scarcer concerning aerosoltherapy in patients admitted to intensive care and especially those undergoing mechanical ventilation. Nevertheless, the physiological effects of bronchodilators and corticosteroids have been documented in patients undergoing mechanical ventilation and several experimental and clinical researches documented the feasibility of inhaled antibiotic therapy in these patients. The thesis comprises five works carried out using methods of experimental bench research, animal experimentation so as clinical and epidemiological research concerning aerosoltherapy in the intensive care setting. The first two works consisted of an international electronic survey among eight hundred physicians working in intensive care and a two-week prospective cross-sectional study in eighty intensive care units. The main results of those works are that aerosoltherapy appeared very common in the intensive care unit and concerned about a quarter of all admitted patients. The molecules administrated were essentially bronchodilatators and corticosteroids, but inhaled antibiotic therapy was also practiced. Although implementation of aerosoltherapy, especially during mechanical ventilation, appeared frequently at odds with optimal practice, or even dangerous, it was well tolerated in the short term since only a hundred side effects were observed during the nine thousand aerosol administrations collected in the prospective study. The third work evaluated, in a bench model of mechanical ventilation, synchronized pneumatic nebulization systems integrated in four intensive care ventilators. The main results of this work are that these systems provided good control of the tidal volume during nebulization ; however inspiratory synchronization was not optimal since a significant proportion of nebulization occurred during expiration, due ti gas compression/decompression upstream of the nebulizer. The fourth work consisted of a clinical study evaluating serum pharmacokinetics of amikacin after high dose inhalation in twenty-two patients undergoing mechanical ventilation and suffering nosocomial pneumonia. Administration was carried out using an innovative pneumatic nebulization system adapted to mechanical ventilation. The main result of this work was that nebulization of 60 mg / kg of amikacin proved feasible in patients on mechanical ventilation and serum concentrations observed were lower than those observed after intravenous infusion. An increase in the dose and / or the yield of the nebulization system may be considered to promote greater lung deposition in order to favour improved efficacy. The presence or absence of a heated humidifier did not influence the results, thus allowing considering active humidification during prolonged nebulization within a high-dose strategy. Finally, the last work was an animal study comparing serum pharmacokinetics of amikacin after intravenous administration, nebulization and in situ aerosolisation at the end of the endotracheal tube in piglets with healthy lungs undergoing mechanical centilation. The main results are that in situ aerosolisation allowed administrating large amounts of amikacin in a very short time. Nevertheless, intra-parenchymal concentrations were very heterogeneous after in situ aerosolisation and often low, while nebulization allowed observing globally more homogeneous concentrations. Immuno-histological amikacin staining allowed observing lung deposition of amikacin at the tissue level.

Drug-drug interactions (DDI) represent a growing concern for the health units. Therefore, monitoring of pharmaceutical prescriptions in hospitals can rationalize pharmacotherapy. To evaluate the effect of pharmaceutical intervention in identifying and managing drug interactions in an intensive care unit (ICU), in Northeastern of Brazil. Methods: Initially, we performed a systematic review from the search of electronic databases, Jan. 1960 to Aug 2010. After that, we realized a longitudinal study in the ICU, in a private hospital in the city of Aracaju-SE, between 2008 and 2009, which was identified in the prevalence and clinical relevance of the DDI. During the study pharmaceutical interventions were aimed at the management of DDI. The systematic review, only seven articles met all inclusion criteria and the specific sample sizes ranged from 200 to 1785 patients. As for the longitudinal study, 6085 prescriptions were collected, of which 213 contained DDI clinically relevant. Of these 178 were moderate and 35 major severity. The clinical pharmacy interventions consisted in the preparation of reports for physicians, allowing the reduction of 40% of all DDI. The data obtained allow inferring that the participation of clinical pharmacists in the DDIs identification and management may have been essential to promote the safety of ICU patients. / As interações medicamentosas (IM) representam uma crescente preocupação para as unidades de saúde. Por isso, o acompanhamento farmacêutico das prescrições nos hospitais pode racionalizar a farmacoterapia. Avaliar o efeito da intervenção farmacêutica na identificação e manejo de interações medicamentosas em uma unidade de terapia intensiva (UTI), no nordeste do Brasil. Inicialmente, foi realizada uma revisão sistemática sobre a qualidade dos estudos que envolvem o papel do farmacêutico na identificação de IM em hospitais, a partir da busca nos bancos de dados eletrônicos, janeiro de 1960 a agosto de 2010. A revisão utilizou como critérios de inclusão: (i) estudos realizados em hospitais; (ii) identificação de IM com a participação do farmacêutico; (ii) texto em língua inglesa. Em seguida, foi realizado um estudo longitudinal, na UTI, em um hospital privado do município de Aracaju-SE, entre 2008 e 2009, no qual foi identificada a prevalência e relevância clínica das IM do tipo fármaco-fármaco. Durante o estudo foram realizadas intervenções farmacêuticas que visavam o manejo da IM. Na revisão sistemática, apenas seis artigos atenderam a todos os critérios de inclusão específicos e o tamanho das amostras variou de 200 a 1785 pacientes. Quanto ao estudo longitudinal, foram coletadas 6.085 prescrições, sendo que 213 continham IM clinicamente relevantes. Destas 178 apresentaram severidade moderada e 35grave. As intervenções da farmácia clínica consistiram na elaboração de laudos para os médicos, que possibilitaram a redução de 40% de todas as interações. Os dados obtidos permitem inferir que a participação do farmacêutico clínico na identificação e manejo de IM, pode ter sido essencial para promover a segurança de pacientes da UTI.
