BACKGROUND: Adequate feeding is a significant challenge for premature infants in the neonatal intensive care unit. These patients are often treated with glycerin suppositories to stimulate the passage of meconium and prevent feeding intolerance. Unfortunately, the evidence for this practice is limited and inconclusive. METHODS: We conducted a systematic review on the use of glycerin suppositories and enemas in premature infants. Following this, we conducted a pilot study for a multicenter randomized controlled trial of premature infants randomized to glycerin suppositories or a placebo procedure once daily. Outcomes included rate of recruitment, rate of reaching the primary endpoint of full enteral feeds, treatment-related adverse events, and cost. RESULTS: Twenty-two infants were recruited and randomized active treatment or the placebo procedure. Gestational age was 24-32 weeks and birth weight was 500-1500 grams. During the study period, 61 infants were screened, 46 (75%) were eligible and approached for consent, 25 (54%) consented to participate, 22 (48%) were randomized, and 19 reached the primary endpoint of full enteral feeds. Three infants (14%) experienced rectal bleeding 5 to 43 days after completing study treatments. An anal fissure was also noted in two of these patients (9%). There were no cases of rectal perforation or necrotizing enterocolitis. Protocol violations occurred during 14 of 130 (11%) treatment days. The total cost for running this pilot study was estimated to be $16,000. A revised sample size calculation for the multicenter study indicated that 72 infants would be required to detect a treatment effect of 2 days faster to full enteral feeds. CONCLUSIONS: This external pilot study suggested that conducting a multicenter randomized controlled trial of glycerin suppositories in premature infants is feasible and safe. In the multicenter trial, we recommend tolerating a lower platelet count in the exclusion criteria, using a fixed rather than variable treatment duration, conducting follow-up assessments at predefined time points, and conducting an interim analysis to ensure that treatment is not associated with increased risk of necrotizing enterocolitis. / Thesis / Master of Science (MSc) / Feeding is a significant challenge for premature babies in the neonatal intensive care unit. These infants have immature digestive tracts and may not have normal bowel movements until a week or more after birth. One way to help premature babies is by giving them a medication called glycerin suppositories. This treatment is already used in many hospitals around the world. Unfortunately, previous studies have not shown for sure that this medication is actually helpful. In fact, there are some signs that using glycerin suppositories in premature infants may be harmful. We conducted a small study involving 22 premature infants randomized to either glycerin suppositories or a placebo. We found that it is safe and practical to do a larger study on this treatment involving multiple hospitals and hundreds of premature babies. The larger study will have enough participants to full show the risks and benefits of using glycerin suppositories to treat these infants.

The diploma thesis is devoted to complications of enteral nutrition in patients with idiopathic inflammatory bowel diseases. The incidence of these diseases has increased in recent years. Nutritional support is an important part of the treatment and the possibility of improving the nutritional status of patients, which plays an important role in responding to other forms of treatment itself or in pre-operative preparation. All forms of artificial nutrition might also cause certain complications. The subject of this work is to observe the complications of enteral nutrition, their solutions and the possibilities of their prevention.

A terapia nutricional mostra-se de grande importância no tratamento do doente crítico, por apresentar impacto favorável em seu desfecho clínico. No entanto, até 70% dos pacientes em unidade de terapia intensiva podem não receber terapia nutricional adequada. Isso ocorre, em parte, pela falta de formação e de conhecimento dos profissionais de saúde sobre princípios de nutrição clínica. O objetivo do presente estudo foi avaliar o impacto da introdução de um programa de educação médica em terapia nutricional em uma unidade de terapia intensiva sobre a qualidade da terapia nutricional e os resultados clínicos de seus pacientes. O presente estudo foi desenvolvido em três fases distintas: 1) Pré-programa educacional (PP): 50 pacientes recém-admitidos em unidade de terapia intensiva foram selecionados consecutivamente para avaliação da qualidade da terapia nutricional a eles oferecida e seus desfechos clínicos, através de visitas periódicas. 2) Programa Educacional (PE): foram criados protocolos nutricionais específicos. Um programa de educação em terapia nutricional baseado nesses protocolos (palestras, workshops e discussões à beira leito) foi introduzido nessa unidade de terapia intensiva. 3) Pós-programa educacional (PO): a qualidade da terapia nutricional e os desfechos clínicos de um segundo grupo de 50 pacientes foram avaliados, utilizando-se a mesma metodologia da fase 1 (PP). Os marcadores utilizados para avaliação da qualidade da terapia nutricional foram: avaliação nutricional, adequação da oferta de energia, tempo de jejum e introdução de nutrição enteral precoce. Tempo de permanência na unidade de terapia intensiva e tempo de internação hospitalar foram registrados e avaliados como desfechos clínicos principais. Os pacientes da fase PP e PO não diferiram em idade, APACHEII, sexo, tipo de diagnóstico na admissão e avaliação nutricional. Observou-se redução no tempo de jejum (PP 3,8 dias ± 3,1 vs PO: 2,2 dias ± 2,6; p = 0,002), melhora na adequação calórica (PP 74,2% ± 33,3 vs PO 96,2 ± 23,8%; p <0,001) e aumento da indicação de nutrição enteral precoce (PP 24% vs PO 60%; p = 0,001) nos pacientes da fase PO, em comparação com os pacientes da fase PP. Além disso, o tempo de permanência na unidade de terapia intensiva foi menor (PP: 21,9 dias ± 15,2 vs PO: 12,2 dias ± 8,0; p <0,001) nos pacientes da fase PO, em comparação com os pacientes da fase PP. Não houve alteração significativa no tempo de internação hospitalar. A introdução de um modelo de educação em terapia nutricional em uma unidade de terapia intensiva melhorou a qualidade da terapia nutricional e diminuiu o tempo de permanência de seus pacientes / In critically ill patients, nutritional therapy favorably impacts clinical outcomes. However, up to 70% of patients in the intensive care unit do not receive adequate nutritional therapy, due, partially, to the lack of training and knowledge regarding nutrition principles among healthcare providers. The aim of this study was to evaluate the impact of a medical educational program in an intensive care unit on the quality of the nutritional therapy and clinical outcomes. The study protocol was developed among three distinct phases: 1) Pre-educational program (Pre-EP): 50 patients newly admitted to the intensive care unit were consecutively selected to assess their regular performed nutritional therapy and clinical end-points. 2) Educational program (EP): specific nutritional protocols were created and an education program (lectures, workshops and bedside discussions) were implemented. 3) Post educational program (Post-EP): a second group of 50 patients was enrolled and observed using the same phase 1 (Pre-EP) methodology. Nutritional therapy practice was evaluated through the application of specific quality indicators and the evaluation of nutritional therapy-related complications, considering as main markers the nutritional assessment, adequacy of energy requirement, duration of fasting and use of early enteral nutrition. Intensive care unit length of stay and hospital length of stay were recorded and measured as primary end-points. The Pre-EP and Post-EP patients did not differ in age, APACHEII, gender, admission diagnosis (surgery x medical) and nutritional assessment. Duration of fasting decreased (Pre-EP 3.8 days ±3.1 vs. Post-EP: 2.2 days ±2.6; p=0.002), the adequacy of nutritional therapy improved (Pre-EP 74.2% ±33.3 vs. Post-EP 96.2%±23.8; p<0.001) and enteral nutrition was earlier initiated (Pre-EP 24% vs. Post-E 60%; p=0.001). Intensive care unit length of stay also decreased (Pre-EP: 21.9 days±15.2 vs Post-EP: 12.2 days ±8.0; p<0.001). No changes were observed in hospital length of stay. Conclusion: Implementing a medical nutrition educational model in an intensive care unit improved the quality of nutritional therapy and decreased the length of stay of their patients

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

Introdução: No acompanhamento diário de pacientes que realizam troca de sonda de gastrostomia endoscópica percutânea (GEP), observa-se a preco- cidade com que ocorrem essas trocas devido à curta durabilidade da sonda, especialmente decorrente da ruptura do balão interno da sonda. Objetivo: Este estudo prospectivo visou à avaliação da durabilidade de cinco diferen- tes marcas de sondas de troca de GEP. Método: Cem procedimentos con- secutivos de troca de sonda de GEP (realizados em 65 pacientes) foram dis- tribuídos, a cada grupo de 20 procedimentos, em cinco grupos determinados pelas marcas de sondas avaliadas (Kangaroo®, Wilson Cook®, Silmag®, Fre- ka® e Bard®). Conforme o protocolo proposto, após a troca, os pacientes fo- ram seguidos ao longo de seis meses, e, nesse período, foram realizadas três avaliações para verificação de eventuais intercorrências. Para avaliação da durabilidade das sondas, foi considerado o período de permanência dos pacientes no protocolo, determinada pelo término do período de estudo ou pela necessidade de troca da sonda por ruptura do balão ou desgaste do tubo ou da tampa. As curvas de durabilidade das sondas foram determina- das pelo Método de Kaplan Meier e pelo Modelo de Regressão de Cox. Resultados: Houve variações importantes na durabilidade das sondas quando considerados os três motivos de troca da sonda associados. Essa diferença não foi observada quando se considerou apenas a ruptura do balão, cujas ocorrências se mostraram associadas com pacientes em uso de GEP por distúrbios neurológicos sem diagnóstico. A durabilidade das sondas foi tanto menor, quanto maior o número de trocas anteriores. Conclusões: A marca da sonda de troca de GEP não influenciou a sua durabilidade quando deter- minada pela ruptura do balão, mas, quando determinada também por des- gaste em tubo e tampa, as sondas Wilson Cook® apresentaram durabilidade significativamente maior do que as sondas Silmag® e Bard®. O número de trocas anteriores se mostrou fator determinante de menor durabilidade das sondas / Introduction: During the follow-up of patients after replacement of percuta- neous endoscopic gastrostomy (PEG) tubes, the early need of new replace- ments seems to be consequence of the short durability of the tubes, espe- cially due to the rupture of their internal balloon. Objectives: In this prospec- tive study, the durability of five different PEG tubes was estimated. Methods: One hundred consecutive procedures (in 65 patients) for replacing PEG tubes were divided into five groups determined by the tubes model: Kanga- roo®, Wilson Cook®, Silmag®, Freka® and Bard®. According to the protocol developed for the study, patients were followed up along six months, and three evaluations for verifying eventual outcomes were carried out during this period. Estimation of the tubes durability considered the time patients re- mained in the protocol, which was determined by the termination of the follow up period or by the need for replacing the tubes due to the balloon rupture or to the loss of use of tube or cover. Curves of tubes durability were estab- lished by applying the Kaplan-Meier Method and the Cox Regression Model. Results: Important variations of the tubes durability were observed when the three causes for replacement were considered all together. Differences were not observed when considered only the balloon rupture, which was associated with patients using PEG in virtue of not specified neurologic disorders. Shorter tubes durability was associated with more previous replacements. Spontaneous opening of the cover and slipping of the external protection were significantly less frequent in the Freka® tubes, although such outcomes did not determined the tubes durability. Conclusion: The model of PEG re- placement tubes did not influence their durability regarding the balloon rup- ture alone. Considering such occurrence associated with problems in tubes or covers, the longest durability was observed in Wilson Cook®, followed by Freka, ® Kangaroo®, Silmag® and Bard® tubes. The number of previous re- placements showed to be determining factor for the tubes durability

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.

Introdução: O reconhecimento da importância da nutrição enteral em pacientes hospitalizados gerou novos métodos de administração, o que leva a muitas perguntas: quais são os efeitos cronobiológicos da terapia nutricional contínua ou intermitente? Objetivo: O objetivo deste estudo foi avaliar o efeito do horário de administração da nutrição enteral como Zeitgeber do ritmo biológico no gasto energético e consumo de oxigênio, mensurados por calorimetria indireta. Métodos: Ensaio clínico randomizado, realizado de dezembro de 2009 a novembro de 2010, em 34 pacientes com doença neurológica, com idade entre 52 e 80 anos, alimentados através de uma sonda nasoenteral, 15 através de infusão contínua por 24 horas/dia e 19 em quantidades comparáveis de forma intermitente, a cada 4 horas, dás 8 às 20 horas. Foram realizadas 4 medidas de calorimetria indireta nas 24 horas (A: 07:30 h, B: 10:30 h, C: 14:30 h e D :21:30 horas), durante 3 dias, para cada paciente. Resultados: A idade média foi de 69,5±8,50% eram do sexo masculino, IMC 22 ±3,9 kg/m²(homens) e 25±5,6 kg/m²(mulheres). O gasto energético e o consumo de oxigênio mostrou diferença significativa entre os grupos contínuo e intermitente: 1478±817 kcal/24h, (IC: 1249 – 1706), 1782±862 kcal/24h (IC: 1579 – 1984) (p=0.05); 212±117 ml/min (IC: 179 – 245); 257±125 ml/min (IC: 227 – 286) (p=0.048), respectivamente. No gasto energético e consumo de oxigênio diferenças estatisticamente significativas foram encontradas entre as mensurações A, B, C e D em ambos os grupos. Comparando o gasto energético e consumo de oxigênio entre os grupos por Mann-Whitney, houve uma diferença estatisticamente significativa em tempo B e C (p = < 0,01). Conclusão: Foi observado neste estudo uma variação circadiana do gasto energético e consumo de oxigênio nos dois métodos de administração da nutrição enteral, sugerindo que apenas uma medida de calorimetria indireta no dia não é capaz de mostrar a verdadeira necessidade do paciente. Observamos também que o gasto energético foi mais elevado à noite nos dois métodos de administração da alimentação. Além disso, o gasto energético e o consumo de oxigênio foi maior no método de administração intermitente em todos os tempos. / Introduction: The importance of enteral nutrition has grown in recognition resulting in new methods of administration. That leads to many questions such as: what are the chronobiologic effects of continuous or intermittent nutrition therapy? Objectives: The aim of this study was to evaluate the use of enteral nutrition as a Zeitgeber of biological rhythm. Energy expenditure and oxygen consumption were measured by indirect calorimetry in continuous or intermittent nutrition patterns. Methods: A randomized clinical trial was conducted from December 2009 to November 2010. Thirty four neurological patients received through the same kind of calibrated nasogastric tube the standard protein and energy intakes calculated for each subject, 15 through continuous infusion for 24 hours/day and 19 intermittently in comparable quantities, every 4 hours, from 8:00 to 20:00 h. Four indirect calorimetry measures were carried out during the 24 hours (A: 07:30h, B: 10:30h, C: 14:30h and D: 21:30h), for 3 days, for each patient. Results: The mean age was 69.5±8, 50% were male; BMI 22±3.9kg/m² (men), 25±5.6 kg/m² (women). Energy expenditure end oxygen consumption presented a significant difference between the continuous and intermittent groups (1478±817 kcal/24h, (CI: 1249 – 1706), 1782±862kcal/24h (CI: 1579 – 1984) (p=0.05); 212±117 ml/min (CI: 179 – 245); 257±125 ml/min (CI: 227 – 286) (p= 0.048), respectively). In the energy expenditure and oxygen consumption, statistically significant differences were found between the A, B, C and D measures in both groups. By comparing the energy expenditure and the oxygen consumption between the groups by the Mann-Whitney test a statistically significant difference was observed for times B and C (p=< 0.01). Conclusion: A circadian variation of energy expenditure and oxygen consumption was observed in both enteral nutrition administration methods used in this work, suggesting that only one indirect calorimetry measure per day is not able to show the patient’s true needs. It was also observed that the energy expenditure was higher at night in both food administration methods. Moreover, the energy expenditure and oxygen consumption was higher in the intermittent administration method in all times.

Syftet med denna systematiska litteraturstudie som inkluderar 18 artiklar, har varit att belysa vilka nutritionsstöd som kan förebygga och behandla malnutrition hos barn med cancer samt vilka omvårdnadsbehov som finns i samband med nutritionsbehandling. Resultatet visade att barn med cancer som behandlas med strålning och/eller cytostatika ofta drabbas av olika biverkningar som påverkar nutritionen. Cirka 46 % av barnen utvecklade malnutrition. Näringsintaget försämrades ofta på grund av biverkningarna vilket fick till följd att behandlingen försämrades samt tillväxt och utveckling påverkades negativt. Olika sätt fanns för att upprätthålla gott nutritionsstatus. Oralt intag förordades för att upprätthålla mag- tarmkanalens struktur och funktion. Alternativ för kostbehandling när barnet inte klarade att inta oral kost var nasogastrisk sond (NS), Perkutan Endoskopisk Gastrostomi (PEG) och Total Parenteral Nutrition (TPN). NS visade sig vara relativt biverkningsfritt och ett alternativ att tillgå under kortare nutritionsbehandlingar. PEG var ett gott alternativ med relativt få biverkningar då barnet behöver nutritionsstöd under längre tid. TPN var ett alternativ enbart då barnet inte kunde äta relaterat till bristande upptag i mag- tarmkanalen. Försämrat näringsintag påverkade barnets livskvalitet. Familjen påverkades genom att ätandet var en stark källa till konflikt mellan barnet och föräldrarna. Det var viktigt att barnet och familjen fick stöd i barnets förmåga att kunna äta samt att erbjudas näringsrik kost. Bedömning av nutritionsstatus och dokumentation av oralt intag, parenteralt intag och effekter av nutritionsbehandlingen var av stor vikt för att kunna ge barnet optimal omvårdnad.

Background: Ventilator associated pneumonia (VAP) is a major cause of morbidity, longer intensive care unit (ICU) stay, increased duration of mechanical ventilation, and increased healthcare cost in critically ill patients. Critically ill patients are at increased risk for malnutrition, which is associated with impaired immune function, impaired ventilator drive and weakened respiratory muscles. Malnutrition has been thought to increase the risk of VAP due to bacterial translocation from the gastrointestinal tract to the lungs. Previous research that has evaluated the effect of enteral nutrition on malnutrition associated with VAP has been inconsistent in part because of the subjectivity of the old definition of VAP. In 2013, the Center for Disease Control and Prevention (CDC) developed a new definition for the diagnosis of VAP, which includes three tiers of a ventilator associated event (VAE); ventilator associated condition, infection-related ventilator-associated complication, or possible or probable VAP). The purpose of this study is to retrospectively examine the relationship between enteral formula, tube-feeding placement site, time of tube feeding initiation and the incidence of VAE using this new CDC definition. Objective: The aim of the study was to retrospectively examine the relationship between enteral formula, tube-feeding placement site, time of tube feeding initiation and the incidence of VAE using this new CDC definition. Participants/setting: The medical records of 162 adult patients admitted to one of the ICUs (Medical ICU, Surgical ICU, Neurological ICU, Burn ICU) at Grady Memorial Hospital (GMH) in Atlanta, GA in 2013 Main outcome measures: Demographic and baseline medical characteristics including the type of enteral formula used (standard, immune-modulating, hydrolyzed, immune-modulating and hydrolyzed, or mixed), enteral tube feeding placement (gastric or small bowel), and timing of enteral nutrition (never fed, fed48 hours after admission) were collected. Statistical analysis: Demographic and baseline medical characteristics were described using frequency statistics and compared by VAE status using the Mann-Whitney U and Kruskal-Wallis tests. The relationship between tube placement, enteral formula, timing of feeding and the diagnosis of a VAE was evaluated using the Chi-square test. Results: In 2013, 81 patients admitted to the ICU at GMH were diagnosed with a VAE. The median age of the study population (n=162) was 50 years (range, 19 to 88 years) and the median BMI was 27.6 kg/m2 (range, 13.2 to 83.2 kg/m2). The majority of the population was African American (53.1%) and male (64.2%). Most patients were fed through a gastric tube (86.4%), were given an immune-modulating enteral formula (32.1%) and were fed after 48 hours of admission (44.4%). After subdividing by ICU location, 12 of 14 patients (86%) in the Medical ICU who were diagnosed with a VAE were either never fed or fed >48 hours after admission vs. 7 of 13 (54%) of patients in the Medical ICU who were not diagnosed with a VAE (p=0.031). No other relationships between the type of feeding initiation, tube placement, and enteral formula were found by VAE status for the population or by ICU location. Conclusion: Adults admitted to the Medical ICU may have a reduced risk of developing a VAE if fed within 48 hours of admission. The type of enteral formula provided and the route of administration was not associated with the diagnosis of VAE. Future prospective studies should include all critical care patients to further evaluate the effect of nutrition on VAE outcome.
