Transfusão de eritrócitos em crianças internadas em unidade de terapia intensiva pediátrica

JUSTIFICATIVA E OBJETIVOS: As indicações de transfusão de eritrócitos não estão bem estabelecidas em crianças gravemente enfermas. O objetivo deste estudo foi descrever a prática da transfusão de eritrócitos na UTI Pediátrica do Hospital de Clínicas da Universidade Estadual Paulista (HC-UNESP). MÉTODO: Estudo retrospectivo observacional realizado durante o ano de 2003. RESULTADOS: Setenta e cinco pacientes receberam transfusão, havendo registro de 105 indicações. Mais da metade dos pacientes (53,3%) tinha menos que um ano de idade. Taquipnéia (75,2%), palidez (65,7%) e hipotensão (51,4%) foram os registros mais freqüentemente observados antes da transfusão. Além disso, a gasometria evidenciou acidose metabólica (68,08%) e hipoxemia (63,8%). Dos 93 registros de valores de hemoglobina (Hb), 54 (58,1%) estavam entre 7 e 10 g/dL e dos 90 registros de hematócrito (Ht) observou-se que 66 (73,3%) apresentavam valores entre 21% e 30%. As principais indicações de transfusão foram anemia em 75 crianças (71,4%) e sangramento ativo em 26 (24,7%). O valor médio de Hb antes da transfusão foi de 7,82 ± 2,82 g/dL. Sete transfusões foram indicadas para pacientes com valores de Hb > 10 g/dL, crianças estas em pós-operatório imediato de intervenção cirúrgica cardíaca e casos de choque séptico. CONCLUSÕES: A transfusão de eritrócitos vem sendo utilizada criteriosamente, com indicações restritivas (Hb entre 7 e 10 g/dL). Nem sempre há anotação dos valores de Hb imediatamente antes da transfusão. A partir deste estudo, foi elaborado um protocolo de indicação de transfusão na unidade.

Comparison between intermittent mandatory ventilation and synchronized intermittent mandatory ventilation with pressure support in children

Objective: To compare intermittent mandatory ventilation (IMV) with synchronized intermittent mandatory ventilation plus pressure support (SIMV+PS) in terms of time on mechanical ventilation, duration of weaning and length of stay in a pediatric intensive care unit (PICU).Methods: This was a randomized clinical trial that enrolled children aged 28 days to 4 years who were admitted to a PICU between October of 2005 and June of 2007 and put on mechanical ventilation (MV) for more than 48 hours. These patients were allocated to one of two groups by drawing lots: IMV group (IMVG; n = 35) and SIMV+PS group (SIMVG; n = 35). Children were excluded if they had undergone tracheotomy or had chronic respiratory diseases. Data on oxygenation and ventilation were recorded at admission and at the start of weaning.Results: There were no statistical differences between the groups in terms of age, sex, indication for MV, PRISM score, Comfort scale, use of sedatives or ventilation and oxygenation parameters. The median time on MV was 5 days for both groups (p = 0.120). There were also no statistical differences between the two groups for duration of weaning [IMVG: 1 day (1-6) vs. SIMVG: 1 day (1-6); p = 0.262] or length of hospital stay [IMVG: 8 days (2-22) vs. SIMVG: 6 days (3-20); p = 0.113].Conclusion: Among the children studied here, there was no statistically significant difference between IMV and SIMV+ PS in terms of time on MV, duration of weaning or time spent in the PICU.ClinicalTrials.govID: NCT00549809.

Opinião de familiares sobre a internação de crianças em uma Unidade de Terapia Intensiva Pediátrica

A Pediatric Intensive care Unit (PICU) is an environment where care is provided to seriously ill children. Hospitalization is regarded as an unpleasant experience that requires adaptation and routine change. To assess the opinion of relatives of children hospitalized at a PICU concerning tie breakage and/or separation between children and their families. It is a descriptive, cross-sectional, quantitative study. A structured interview was conducted with the families of hospitalized children from July to September, 2010. The data were statistically analyzed. RESULTS: Twenty relatives were interviewed, 80% of whom believed that children’s behavior changes when they are present in the unit, and 85% considered the visitation time established to be sufficient. All the respondents reported to be satisfied about the care provided. The feelings prevailing in 50% of the relatives were fear and hope. Change in the family’s union after hospitalization occurred in 85% of the families. The most fearful aspect concerning the ICU is the equipment (25%), and the most worrisome, as regards personal life, is the separation from other children (65%). Health care professionals must pay more attention to relatives by including them in their health care plan so that the health care team and the family, who are essential in children’s recovery, can interact in a congenial fashion. It is also necessary to improve the knowledge related to that subject so that the health care team and families can work together towards children’s recovery

Comparison between noninvasive mechanical ventilation and standard oxygen therapy in children up to 3 years old with respiratory failure after extubation: a pilot prospective randomized clinical study

Objectives: The effectiveness of noninvasive positive-pressure ventilation in preventing reintubation due to respiratory failure in children remains uncertain. A pilot study was designed to evaluate the frequency of extubation failure, develop a randomization approach, and analyze the feasibility of a powered randomized trial to compare noninvasive positive-pressure ventilation and standard oxygen therapy post extubation for preventing reintubation within 48 hours in children with respiratory failure.Design: Prospective pilot study.Setting: PICU at a university-affiliated hospital.Patients: Children aged between 28 days and 3 years undergoing invasive mechanical ventilation for greater than or equal to 48 hours with respiratory failure after programmed extubation.Interventions: Patients were prospectively enrolled and randomly assigned into noninvasive positive-pressure ventilation group and inhaled oxygen group after programmed extubation from May 2012 to May 2013.Measurements and Main Results: Length of stay in PICU and hospital, oxygenation index, blood gas before and after tracheal extubation, failure and reason for tracheal extubation, complications, mechanical ventilation variables before tracheal extubation, arterial blood gas, and respiratory and heart rates before and 1 hour after tracheal extubation were analyzed. One hundred eight patients were included (noninvasive positive-pressure ventilation group, n = 55 and inhaled oxygen group, n = 53), with 66 exclusions. Groups did not significantly differ for gender, age, disease severity, Pediatric Risk of Mortality at admission, tracheal intubation, and mechanical ventilation indications. There was no statistically significant difference in reintubation rate (noninvasive positive-pressure ventilation group, 9.1%; inhaled oxygen group, 11.3%; p > 0.05) and length of stay (days) in PICU (noninvasive positive-pressure ventilation group, 3 [116]; inhaled oxygen group, 2 [1-25]; p > 0.05) or hospital (noninvasive positive-pressure ventilation group, 19 [7-141]; inhaled oxygen group, 17 [8-80]).Conclusions: The study indicates that a larger randomized trial comparing noninvasive positive-pressure ventilation and standard oxygen therapy in children with respiratory failure is feasible, providing a basis for a future trial in this setting. No differences were seen between groups. The number of excluded patients was high.

Perfil dos pacientes internados em uma unidade de terapia intensiva pediátrica de um hospital escola do interior de São Paulo

The purpose of the study was to outline the profile of patients hospitalized at the Pediatric Intensive Care Unit of the Hospital das Clínicas de Botucatu - UNESP. This is a descriptive, cross-sectional and quantitative study. The data were extracted from the “Discharge, Admission and Death Register” of the unit of the patients hospitalized between January and December 2011. There was predominance of male children (54.4%) under one year of age (40,7%) were, with a mean length of stay of 5.46 days. Most of these children came from cities included in the DIR XI/SP in Botucatu (78.2%). The discharge contributed with 91.1% of the total discharges from the unit. Most admissions happened during the fall and winter, with the Immediate Post-Operative (IPO - 32.3%) and respiratory diseases (24.2%) as the most frequent causes. The profile of patients at the PICU makes it possible to elucidate individual aspects, family, social, demographic, seasonal, climatic, and, also, the clinical conditions, and, thus, comprehend the context of hospitalizations, in order to propose improvements on assistance, in an individualized and integral manner, for patients and their families.
