Evaluación de la validez de la escala llanto para el dolor en neonatos y menores de cinco años

Introducción: La escala LLANTO para dolor es una escala que hasta la fecha ha sido solo validada en población infantil española, actualmente no se conocen datos en población colombiana. Se pretende validar la escala de dolor LLANTO en pacientes neonatos y menores de 5 años, a través de su aplicación en pacientes atendidos en una de tres instituciones, además comparándola con las escalas FLACC y PIPP dependiendo de edad del paciente. Metodología: Se incluyeron niños con cualquier tipo de dolor, clasificándolos en dos grupos por edad: 1) neonatos y 2) niños entre 1 mes y 5 años de edad, que asistieron a la Fundación Cardioinfantil, Clínica Infantil Colsubsidio o al Hospital Universitario Mayor. Las escalas fueron aplicadas por dos residentes de pediatría y una enfermera especializada en el cuidado de población infantil. Para la prueba piloto se diseñó un cuestionario determinar dificultades en la aplicación de la escala LLANTO. Una vez corregidos los problemas identificados se procederá a la validación de la escala. Resultados: Se presentan los datos de la prueba piloto. Se incluyeron 8 neonatos y 8 niños entre 1 mes y 5 años, esta muestra fue obtenida en un periodo de un mes, con la encuesta se evaluó la aceptación y entendimiento de la escala LLANTO por parte de los evaluadores. La prueba piloto mostró resultados favorables en el 100% de los encuestados. Discusión: Se considera que la escala LLANTO no requiere cambios para continuar con su validación.

Trauma craneoencefálico severo en la UCIP del Hospital de la Misericordia, 2010-2013

El Trauma Craneoencefálico (TCE) infantil constituye un motivo frecuente de consulta en Urgencias y supone la primera causa de muerte en niños, llegando a ser hasta del 50% en trauma severo. En Colombia se conocen cifras de TCE por algunos estudios descriptivos, pero no existen reportes en Bogotá ni específicamente en TCE severo. Objetivo: Caracterizar el trauma craneoencefálico severo pediátrico en la Unidad de Cuidado intensivo del Hospital de la Misericordia entre los años 2010 y 2013. Materiales y métodos: Un estudio descriptivo retrospectivo fue realizado en el Hospital de la Misericordia mediante revisión de las historias clínicas de los pacientes que ingresaron a la Unidad de Cuidado Intensivo pediátrico con diagnóstico de trauma craneoencefálico severo entre el año 2010 al 2013. Resultados: Se incluyeron 63 pacientes (71,4% hombres) con una edad mediana de 4 años (RIQ 2-8). La mayoría de los traumas fueron originados por caída o accidente de tránsito (79,4%). La principal lesión fue fractura de cráneo (79%). Casi la mitad de los pacientes sufrieron algún tipo de secuela neurológica al egreso (47,1%). La mayoría de los pacientes que murieron (19%) sufrieron choque hipovolémico (83,3%) y presentaron trauma asociado (66,7%). Conclusión: Las características y epidemiología del trauma craneoencefálico en nuestra población muestran claras similitudes con lo reportados en otras series de la literatura mundial y de Colombia, excepto por la mortalidad, que se esperaba más alta al estudiar solo pacientes con TCE severo.

O significado de qualidade de vida para cuidadores de enfermagem de uma unidade de terapia intensiva adulto

Quality of life of nursing caregivers who work in the ICU has been the focus of several studies in recent decades. This study aimed to identify the meaning of quality of life given by nursing caregivers working in ICUs for adults. This was a descriptive exploratory study with a qualitative approach. There were five central themes that gave direction to the meaning of quality of life: QOL as biopsychosociospiritual welfare; time for family and social life; QOL related to leisure; professional achievement as a source of QOL; and financial stability. The findings suggest that the meaning of quality of life is subjective, because it depends on the importance of the factors that nursing caregivers attaches to their life, such as those related to personal needs, resources and training materials for their job performance and professional achievement, as well as being valued by means of economic stability.

A actuação do enfermeiro como gestor na unidade de terapia intensiva do Hospital Regional do Baixo Amazonas-Santarém-Pará-Brasil : um estudo de caso

Estudo descritivo que teve como objetivo avaliar a atuação do enfermeiro como gestor da Unidade de Terapia Intensiva do Hospital Regional do Baixo Amazonas Dr. Waldemar Pena – HRBA, o qual obteve o selo de Acreditado em Nível 1 em 2012. Para a obtenção dos dados utilizou-se um questionário elaborado com 10 perguntas subjetivas e aplicado aos enfermeiros gerentes que atuam nas Unidades de Terapia Intensiva e CTI do HRBA. Verificou-se nesse estudo que são indivíduos na faixa etária de 25 a 45 anos, com predominância do gênero feminino, com especialização em áreas diversas da enfermagem. Na atuação no setor de gerência, os enfermeiros estabelecem prioridades, direcionando sua equipe para os atendimentos assistenciais complexos aos pacientes, ficando o trabalho burocrático para ser realizado por último. Os entraves relatados são a insatisfação e o desgaste no exercício da função de gerente da unidade devido ao excesso de funcionários sem experiência em UTI, falta de autonomia, dupla jornada de trabalho, excesso de burocracia entre outras situações que se tornam motivos de estresse. Concluiu-se que a atuação do enfermeiro como gerente se respalda na função assistencial ao paciente através de cuidados diretos e indiretos e na organização dos trabalhos burocráticos na Unidade de Terapia Intensiva.

The effect of selective decontamination of the digestive tract on mortality in multiple trauma patients: a multicenter randomized controlled trial

Objective: Evaluation of selective decontamination of the digestive tract (SDD) on late mortality in ventilated trauma patients in an intensive care unit (ICU). Methods: A multicenter, randomized controlled trial was undertaken in 401 trauma patients with Hospital Trauma Index-Injury Severity Score of 16 or higher. Patients were randomized to control (n = 200) or SDD (n = 201), using polymyxin E, tobramycin, and amphotericin B in throat and gut throughout ICU treatment combined with cefotaxime for 4 days. Primary endpoint was late mortality excluding early death from hemorrhage or craniocerebral injury. Secondary endpoints were infection and organ dysfunction. Results: Mortality was 20.9% with SDD and 22.0% in controls. Overall late mortality was 15.3% (57/372) as 29 patients died from cerebral injury, 16 SDD and 13 control. The odds ratio (95% confidence intervals) of late mortality for SDD relative to control was 0.75 (0.40-1.37), corresponding to estimates of 13.4% SDD and 17.2% control. The overall infection rate was reduced in the test group (48.8% vs. 61.0%). SDD reduced lower airway infections (30.9% vs. 50.0%) and bloodstream infections due to aerobic Gram-negative bacilli (2.5% vs. 7.5%). No difference in organ dysfunction was found. Concluson: This study demonstrates that SDD significantly reduces infection in multiple trauma, although this RCT in 401 patients was underpowered to detect a mortality benefit.

Characteristics of Acute Kidney Injury in Patients Infected with the 2009 Influenza A (H1N1) Virus

Background and objectives: There have been few studies investigating acute kidney injury (AKI) in patients infected with the 2009 pandemic influenza A (H1N1) virus. Therefore, the objective of this study was to identify the factors associated with AKI in H1N1-infected patients. Design, setting, participants, & measurements: This was a study of 47 consecutive critically ill adult patients with reverse transcriptase-PCR-confirmed H1N1 infection in Brazil. Outcome measures were AKI (as defined by the Risk, Injury, Failure, Loss, and End-stage renal failure [RIFLE] criteria) and in-hospital death. Results: AKI was identified in 25 (53%) of the 47 H1N1-infected patients. AKI was associated with vasopressor use, mechanical ventilation, high Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, and severe acidosis as well as with higher levels of C-reactive protein and lactic dehydrogenase upon intensive care unit (ICU) admission. A nephrology consultation was requested for 16 patients (64%), and 8 (50%) required dialysis. At ICU admission, 7 (15%) of the 25 AKI patients had not yet progressed to AKI. However, by 72 hours after ICU admission, no difference in RIFLE score was found between AKI survivors and nonsurvivors. Of the 47 patients, 9 (19%) died, all with AKI. Mortality was associated with mechanical ventilation, vasopressor use, dialysis, high APACHE II score, high bilirubin levels, and a low RIFLE score at ICU admission. Conclusions: Among critically ill H1N1-infected patients, the incidence of AKI is high. In such patients, AKI is mainly attributable to shock.

Metabolic acidosis in patients with severe sepsis and septic shock: A longitudinal quantitative study

Objective: To describe the composition of metabolic acidosis in patients with severe sepsis and septic shock at intensive care unit admission and throughout the first 5 days of intensive care unit stay. Design: Prospective, observational study. Setting: Twelve-bed intensive care unit. Patients: Sixty patients with either severe sepsis or septic shock. Interventions: None. Measurements and Main Results: Data were collected until 5 days after intensive care unit admission. We studied the contribution of inorganic ion difference, lactate, albumin, phosphate, and strong ion gap to metabolic acidosis. At admission, standard base excess was -6.69 +/- 4.19 mEq/L in survivors vs. -11.63 +/- 4.87 mEq/L in nonsurvivors (p < .05); inorganic ion difference (mainly resulting from hyperchloremia) was responsible for a decrease in standard base excess by 5.64 +/- 4.96 mEq/L in survivors vs. 8.94 +/- 7.06 mEq/L in nonsurvivors (p < .05); strong ion gap was responsible for a decrease in standard base excess by 4.07 +/- 3.57 mEq/L in survivors vs. 4.92 +/- 5.55 mEq/L in nonsurvivors with a nonsignificant probability value; and lactate was responsible for a decrease in standard base excess to 1.34 +/- 2.07 mEq/L in survivors vs. 1.61 +/- 2.25 mEq/L in nonsurvivors with a nonsignificant probability value. Albumin had an important alkalinizing effect in both groups; phosphate had a minimal acid-base effect. Acidosis in survivors was corrected during the study period as a result of a decrease in lactate and strong ion gap levels, whereas nonsurvivors did not correct their metabolic acidosis. In addition to Acute Physiology and Chronic Health Evaluation 11 score and serum creatinine level, inorganic ion difference acidosis magnitude at intensive care unit admission was independently associated with a worse outcome. Conclusions: Patients with severe sepsis and septic shock exhibit a complex metabolic acidosis at intensive care unit admission, caused predominantly by hyperchloremic acidosis, which was more pronounced in nonsurvivors. Acidosis resolution in survivors was attributable to a decrease in strong ion gap and lactate levels. (Crit Care Med 2009; 37:2733-2739)

Clustering Lab value working with medical data

Data mining is a relatively new field of research that its objective is to acquire knowledge from large amounts of data. In medical and health care areas, due to regulations and due to the availability of computers, a large amount of data is becoming available [27]. On the one hand, practitioners are expected to use all this data in their work but, at the same time, such a large amount of data cannot be processed by humans in a short time to make diagnosis, prognosis and treatment schedules. A major objective of this thesis is to evaluate data mining tools in medical and health care applications to develop a tool that can help make rather accurate decisions. In this thesis, the goal is finding a pattern among patients who got pneumonia by clustering of lab data values which have been recorded every day. By this pattern we can generalize it to the patients who did not have been diagnosed by this disease whose lab values shows the same trend as pneumonia patients does. There are 10 tables which have been extracted from a big data base of a hospital in Jena for my work .In ICU (intensive care unit), COPRA system which is a patient management system has been used. All the tables and data stored in German Language database.

The effectiveness of proactive telephone support provided to breastfeeding mothers of preterm infants : study protocol for a randomized controlled trial

Background: Although breast milk has numerous benefits for infants' development, with greater effects in those born preterm (at < 37 gestational weeks), mothers of preterm infants have shorter breastfeeding duration than mothers of term infants. One of the explanations proposed is the difficulties in the transition from a Neonatal Intensive Care Unit (NICU) to the home environment. A person-centred proactive telephone support intervention after discharge from NICU is expected to promote mothers' sense of trust in their own capacity and thereby facilitate breastfeeding. Methods/design: A multicentre randomized controlled trial has been designed to evaluate the effectiveness and cost-effectiveness of person-centred proactive telephone support on breastfeeding outcomes for mothers of preterm infants. Participating mothers will be randomized to either an intervention group or control group. In the intervention group person-centred proactive telephone support will be provided, in which the support team phones the mother daily for up to 14 days after hospital discharge. In the control group, mothers are offered a person-centred reactive support where mothers can phone the breastfeeding support team up to day 14 after hospital discharge. The intervention group will also be offered the same reactive telephone support as the control group. A stratified block randomization will be used; group allocation will be by high or low socioeconomic status and by NICU. Recruitment will be performed continuously until 1116 mothers (I: 558 C: 558) have been included. Primary outcome: proportion of mothers exclusively breastfeeding at eight weeks after discharge. Secondary outcomes: proportion of breastfeeding (exclusive, partial, none and method of feeding), mothers satisfaction with breastfeeding, attachment, stress and quality of life in mothers/partners at eight weeks after hospital discharge and at six months postnatal age. Data will be collected by researchers blind to group allocation for the primary outcome. A qualitative evaluation of experiences of receiving/providing the intervention will also be undertaken with mothers and staff. Discussion: This paper presents the rationale, study design and protocol for a RCT providing person-centred proactive telephone support to mothers of preterm infants. Furthermore, with a health economic evaluation, the cost-effectiveness of the intervention will be assessed. Trial registration: NCT01806480

Parent’s experiences of feeding their preterm infant in Neonatal Units in Sweden. : Ethnographic design

Introduction: Studies have shown that having a preterm infant may cause stress and powerlessness for parents. It is important to support parents around the feeding situation, and that the Neonatal Intensive Care Unit (NICU) has appropriate space and place to help the family to bond to each other. For the healthcare professionals it is important to promote skin-to-skin contact and breastfeeding; particularly for preterm infants. There are many studies on parent’s experiences of NICUs and a few studies on parent’s experiences of feeding their infant in the NICU. Objective: The objective of this study was to explore parents experiences of feeding their infant in the NICU. Design: The study was conducted using an ethnographic design. Results: A global theme of ‘The journey in feeding’ was developed from four organising themes: ‘Ways of infant feeding’; ‘Environmental influences’; ‘Relationships’ and ‘Emotional factors’. These themes illustrate the challenges mothers reported with different methods of feeding. The environment had a big impact on parent’s experiences of infant feeding. Some mothers felt that breastfeeding seemed unnatural because their infant was so tiny but breastfeeding and skin-to-skin contact helped them to bond to their infant. The mothers thought it was difficult to keep up with the milk production by only pumping. Routines were not inviting parents to find their own rhythm. They also felt stressed about the weighing. Healthcare professionals had positive and negative influences on the parents. Conclusions: This study demonstrates that while all parents expressed the wish to breastfeed, their ‘journey in feeding’ was highly influenced by method of feeding, environmental, relational and emotional factors. The general focus upon routines and assessing milk intake generated anxiety and reduced relationality. Midwives and neonatal nurses need to ensure that they emphasise and support the relational aspects of parenting and avoid over-emphasising milk intake and associated progress of the infant

Facilitation of learning in specialist nursing training in the PICU : the supervisors´ concerns in the learning situation

With the aim to unfold nurses’ concerns of the supervision of the student in the clinical caring situation of the vulnerable child, clinical nurses situated supervision of postgraduate nursing students in the Pediatric Intensive Care Unit (PICU) are explored. A qualitative approach, interpretive phenomenology, with participant observations and narrative interviews, was used. Two qualitative variations of patterns of meaning for the nurses’ clinical facilitation were disclosed in this study. Learning by doing theme supports the students learning by doing through performing skills and embracing routines. The reflecting theme supports thinking and awareness of the situation. As the supervisor often serves as a role model for the student this might have an immediate impact on how the student applies nursing care in the beginning of his or her career. If the clinical supervisor narrows the perspective and hinders room for learning the student will bring less knowledge from the clinical education than expected, which might result in reduced nursing quality.

Prevalência de perda auditiva em recém-nascidos de muito baixo peso

Objetivos: avaliar a prevalência de alterações auditivas em recém-nascidos de muito baixo peso na Unidade de Tratamento Intensivo Neonatal do Hospital de Clínicas de Porto Alegre e estudar as variáveis que possam estar relacionadas com as alterações da acui-dade auditiva. Métodos: foi realizado um estudo transversal que incluiu todos os recém-nascidos de muito baixo peso admitidos na Unidade de Tratamento Intensivo Neonatal do Hospital de Clínicas de Porto Alegre no período de 1o de setembro de 2001 a 31 de janeiro de 2002. To-dos os pacientes foram submetidos ao exame de otoemissão acústica evocada por produto de distorção no momento da alta hospitalar. O exame foi repetido em 30 dias quando havia alte-ração no primeiro exame. Quando o paciente apresentava o exame de otoemissão acústica al-terada em duas ocasiões, era realizado o potencial auditivo evocado cerebral, considerado al-terado a partir de 35 dB NA. Resultados: foram estudados 96 recém-nascidos. Seis tiveram tanto o exame de otoemissão acústica quanto o potencial auditivo evocado cerebral alterados. A média da idade gestacional foi de 31,5 ± 2,6 semanas, o peso de nascimento variou de 640 a 1.500 g e 57,3% dos pacientes eram do sexo feminino. A idade gestacional e o índice de Apgar no 5o minuto foram inferiores no grupo otoemissão acústica e potencial auditivo evocado cerebral alterados em relação aos demais grupos, atingindo significância limítrofe. Conclusões: a prevalência de perda auditiva nos recém-nascidos de muito baixo peso da Unidade de Tratamento Intensivo Neonatal do Hospital de Clínicas de Porto Alegre foi de 6,3%, tendo sido observadas associações de significância limítrofe com idade gestacional e índice de Apgar no 5o minuto.

Avaliação do impacto de uma intervenção restritiva do emprego de antimicrobianos para o controle de infecção hospitalar em pacientes internados em Unidade de Terapia Intensva

Medidas restritivas de controle de antimicrobianos têm sido propostas para controlar surtos epidêmicos de infecção por germes multirresistentes em hospitais, mas são escassas as publicações a respeito de sua eficácia. Em um estudo quaseexperimental com controles históricos, avaliou-se a efetividade de uma intervenção restritiva ao uso de antimicrobianos para controlar a emergência de germes multirresistentes em uma unidade de cuidados intensivos (UTI) de um hospital geral. Os Serviços de Controle de Infecção e Comissão de Medicamentos restringiu o uso de drogas antimicrobianas em pacientes hospitalizados na UTI a não mais que dois agentes simultaneamente, exceto em casos autorizados por aqueles serviços. A incidência de eventos clínicos e bacteriológicos foi comparada entre o ano que precedeu a intervenção e o ano que a seguiu. No total, 225 pacientes com idade igual ou maior de 15 anos , com infecção, internados na UTI por pelo menos 48 horas, foram estudados no ano precedente a intervenção e 263 no ano seguinte a ela. No ano seguinte à intervenção, um percentual menor de pacientes foi tratado simultaneamente com mais de dois antimicrobianos, mas não houve modificação no número total de antimicrobianos prescritos, na duração e no custo do tratamento. Mortalidade e tempo de internação foram similares nos dois períodos de observação. O número de culturas positivas aumentou depois da intervenção, tanto para germes Gram positivos, quanto para germes Gram negativos, principalmente devido ao aumento do número de isolados do trato respiratório. A maioria dos isolados foi Staphylococcus aureus dentre os Gram positivos e Acinetobacter sp dentre os germes Gram negativos. No ano seguinte à intervenção, a sensibilidade dos microorganismos Gram negativos para carbenicilina, ceftazidima e ceftriaxona aumentou, e para o imipenem diminuiu. A ausência de resposta dessa intervenção sobre desfechos clínicos pode ser em conseqüência da insuficiente aderência ou a sua relativa ineficácia. A melhora da sensibilidade microbiana de alguns germes, semaumento de custos ou a incidência de efeitos adversos, encoraja o uso de protocolos similares de restrição de drogas antimicrobianas para reduzir a taxa de resistência bacteriana na UTI.

Avaliação do risco de exposição ao mercúrio elementar em uma Unidade de Terapia Intensiva

O metal mercúrio é conhecido pela sua grande toxidade apesar de seu emprego difundido. Desde a Antigüidade, se reconhece sua ação tóxica na exposição ocupacional. Em alguns ambientes laborais, os riscos são maiores, como é o caso de hospitais, que utilizam o mercúrio elementar em vários equipamentos, especialmente em termômetros de verificação da temperatura corporal, largamente empregados. Como na instituição objeto deste estudo foram quebrados 148 termômetros em uma Unidade de Terapia Intensiva no período de um ano, esta pesquisa objetivou a realização de uma avaliação de alguns indicadores ambientais neste espaço de trabalho e de alguns indicadores biológicos e psicológicos em uma amostra de trabalhadores desta unidade, que se dispuseram a participar da pesquisa. A avaliação de tais indicadores são recomendados como pertinentes pela literatura (ATSDR, 1989). Não se detectou em nenhuma das avaliações realizadas, índices acima das normas estabelecidas. Interpreta-se que a temperatura da unidade (20ºC) reduz a possibilidade do mercúrio se volatizar e intoxicar os trabalhadores. As regras de higiene, típicas do contexto hospitalar, e a rotina de rápido recolhimento dos resíduos dos termômetros quebrados e seu acondicionamento em recipientes com tampa são os principais fatores explicativos para os índices encontrados.
