ABSTRACT
ABSTRACT Background: Children presenting enuresis are more likely to be asthmatics. The association between enuresis and sleep-disordered breathing has already been demonstrated and several studies have shown at least partial improvement of two thirds or more of the cases of enuresis adenoidectomy. Studies have already described associations between enuresis and allergies but do not assess the repercussions of allergy treatment in enuretics. Objective: This study aims to evaluated whether asthma treatment alters the course of enuresis and whether there is any predictive factor associated with this improvement. Materials and Methods: Twenty patients (5 - 12 years old) with uncontrolled enuresis and asthma, received treatment for asthma. Children were also assessed for the presence of rhinitis and other allergies. The control of asthma was confirmed by a validated questionnaire and primary enuresis by clinical history and wet night diaries. Patients received only asthma treatment. Results: At least partial improvement of enuresis was observed in 55% of the patients with an increase in 64.4% in the number of dry nights at the end of the study (p=0.01). The "presence of other allergies" and "obstruction seen in nasal endoscopy" positively influenced the improvement of urinary symptoms (OR = 3.350; CI 0.844-13.306) and (OR=1.272; CI 0.480-3.370), respectively. Discussion: Until now, only patients presenting upper airway obstruction were known to benefit from the improvement of urinary symptoms when undergoing treatment for their respiratory problems. In our study, we found at least partial improvement in enuresis in 55% of our patients, with only clinical asthma treatment. Conclusion: Controlling asthma in children with primary enuresis resulted in a significant increase in dry nights.

BACKGROUND: The hammock positioning within the incubators simulates the intrauterine environment, however, there is little evidence of its benefits and possible risks. OBJECTIVES: The aim of this study was to assess the effects of hammock positioning on behavioral status, vital signs, and pain in very low birth weight preterm newborns. METHODS: This is a quasi-experimental/case series study in which premature infants (<1500g) were positioned in supine for one hour in a hammock. The preterm newborns were assessed 10min before, during (2, 20, 40, and 60min), and 10min after hammock positioning with the Brazelton Neonatal Behavioral Assessment Scale, vital signs and pain by the Neonatal Facial Coding System. RESULTS: 28 preterm infants between 28 and 36 weeks of gestational age were evaluated. Regarding the behavioral state, the preterm newborns progressively evolved to light or deep sleep during hammock positioning. There was a statistically significant reduction of the heart and respiratory rate from 2 to 60th minute in a hammock, which was maintained after the positioning. The oxygen saturation remained within normal values. No changes in pain scores were observed. CONCLUSION: The hammock positioning can be considered a safe method of positioning that can be used to reduce the stress levels in very low birth weight preterm newborns. We did not observe worsening in either pain or vital signs.

O uso da ventilação não invasiva (VNI) como recurso na fisioterapia respiratória já está bem documentado em adultos, porém pouco se sabe sobre o seu uso em crianças e adolescentes. O objetivo desse estudo foi revisar e sintetizar a literatura sobre o uso da VNI como recurso de auxílio à fisioterapia respiratória pediátrica. Realizou-se revisão sistemática de artigos indexados nas bases de dados do Medline e Scielo de 2004 a 2014, utilizando as palavras chave: ventilação não-invasiva, fisioterapia ou terapia respiratória e pressão positiva. Foram selecionados 15 artigos separados em três categorias: VNI como terapia de reexpansão pulmonar, VNI para otimizar a desobstrução de vias aéreas e VNI durante o treinamento muscular e cardiorrespiratório. Os artigos analisados relatam a eficácia da VNI como recurso adicional à fisioterapia respiratória em pediatria, principalmente no auxílio da reexpansão pulmonar e da depuração mucociliar. A VNI pode ser uma alternativa ou complemento às técnicas de fisioterapia respiratória convencional. As doenças mais comuns a receberem auxílio da VNI na terapia respiratória foram as doenças neuromusculares e a fibrose cística. A VNI também pode melhorar a tolerância ao exercício, principalmente em pacientes de desmame da ventilação mecânica difícil. Porém, ensaios avaliando as diferentes modalidades de VNI como recurso adicional à fisioterapia respiratória pediátrica à longo prazo são necessários.

BACKGROUND: Although self-inflating bags are widely used for manual hyperinflation, they do not allow ventilation parameters, such as pressure or volume, to be set. We studied the ventilation performance of neonatal and pediatric self-inflating bags. METHODS: We asked 22 physiotherapists to manually hyperinflate 2 lung models (neonatal and pediatric), using self-inflating bags from 3 manufactures (Hudson, Laerdal, and JG Moriya), with flows of 0, 5, 10, and 15 L/min. A pneumotachograph recorded tidal volume (V(T)), peak inspiratory pressure (PIP), peak inspiratory flow (PIF), peak expiratory flow (PEF), and inspiratory time. RESULTS: The V(T), PIP, and inspiratory time delivered by the Hudson, Laerdal, and JG Moriya bags, in both neonatal and pediatric self-inflating bags, were significantly different (P < .001). The PEF and PIF delivered were different only when using the neonatal self-inflating bags (P < .001). The V(T), PIP, and PIF delivered with a flow of 0 L/min were lower than with 15 L/min (P < .05) with all the tested bags, in both the neonatal and pediatric sizes. CONCLUSIONS: The performance of the tested neonatal and pediatric bags varied by manufacturer and oxygen flow. There was an increase in VT, PIP, and PIF related to the increase of oxygen flow from 0 L/min to 15 L/min. The neonatal bags showed higher ventilation parameters variation than the pediatric bags.

BACKGROUND: Manual hyperinflation (MH) is used to improve mucociliary clearance and alveolar expansion in mechanically ventilated patients. Despite the popularity of MH, studies with adults have shown considerable variability in the results from its use. This study assessed if professional training on the application of MH influences its performance. METHODS: An experimental study was conducted with physiotherapists, including 11 with previous professional experience (experienced) and 11 without previous experience (inexperienced). They applied MH in a test lung model using self-inflating bags in 2 sizes (infant and pediatric) from 3 manufacturers (Hudson, Laerdal, and JG Moriya). The test lung simulated the lung mechanics of a newborn and a pediatric patient in 2 different clinical situations: at normal and reduced compliance. The professionals were instructed to perform MH as described in the literature. Measurements of inspiratory volume, peak inspiratory pressure, peak inspiratory flow, and peak expiratory flow were recorded using a pneumotachograph in each condition. RESULTS: The delivered peak inspiratory flow was higher in the experienced group (P = .03) than in the inexperienced group. This result was observed in both neonatal and pediatric self-inflating bags. There was no difference in the parameters delivered between the experienced and inexperienced groups. CONCLUSIONS: The experienced and inexperienced groups were similar in their overall MH performance; the only difference was the observation of the highest PIF in the results from the experienced group.

OBJETIVO:O reanimador manual autoinflável é um dispositivo que fornece ventilação com pressão positiva. Pesquisas mostram que, apesar da padronização dos reanimadores manuais autoinfláveis pela American Society for Testing and Materials, diversos fatores afetam o desempenho da ventilação, porém, os resultados são conflitantes. O objetivo desse estudo foi verificar as evidências dos fatores que influenciam a ventilação pulmonar com reanimadores manuais infantil/adulto por meio de uma revisão sistemática da literatura. FONTES DE DADOS: Foram incluídos artigos indexados nas bases Medline, Lilacs e SciELO publicados entre janeiro de 1986 e março de 2011. Utilizaram-se as palavras-chaves: "reanimador manual", "ressuscitador manual", "ventilação manual", "ventilação com pressão positiva", em inglês e português, além de "bag-valve". SÍNTESE DOS DADOS: Foram selecionados 45 artigos, sendo a maioria experimental. Os trabalhos compararam os reanimadores manuais por marcas, modelos e analisaram as características dos profissionais que os utilizam. Estudos verificaram que a eficácia da ventilação com os reanimadores manuais depende da marca, modelo e características funcionais do aparelho utilizado, assim como formação, treinamento e experiência do profissional que os manipula. Outros fatores que podem influenciar são a forma de compressão dos reanimadores manuais, o uso da válvula limitadora de pressão e o fluxo de oxigênio fornecido aos aparelhos. CONCLUSÕES: A variabilidade nos parâmetros ventilatórios fornecidos durante a ventilação com reanimadores manuais não permite uniformizar a técnica, o que prejudica a reanimação cardiopulmonar. Apesar da maioria dos reanimadores manuais parecer estar de acordo com padrões internacionais, os equipamentos devem ser avaliados antes de utilizados no ambiente clínico. Pouco se sabe sobre os modelos pediátricos e neonatais.
OBJECTIVE:The manual resuscitator (RM) is a device that provides positive pressure ventilation. Surveys conducted to assess the adequacy of manual resuscitators to American Society for Testing and Materials standards show that several factors affect manual ventilation. However, results are conflicting. The aim of this study was to verify evidence of factors that influence pediatric/adult pulmonary ventilation with manual resuscitator by a systematic review. DATA SOURCE: Original articles indexed in Medline, Lilacs and SciELO published from January 1986 to March 2011. The key-words used were: "manual resuscitator", "manual ventilation", "positive pressure ventilation" in Portuguese and English, as well as "bag-valve". DATA SYNTHESIS: 45 articles were selected, most of them experimental. The studies compared manual resuscitator brands and models, and analyzed the physical characteristics of professionals. The effectiveness of ventilation with manual resuscitator depends on the brand, model and functional characteristics of the equipment. Ventilation also varies with the education, training and experience of the professional who handles the equipment. Other factors that can influence effectiveness are the manual resuscitator compression form, the use of a pressure relief valve and the flow of oxygen provided to the manual resuscitator. CONCLUSIONS: The variability of ventilatory parameters during manual resuscitation does not allow a standardization of the technique, being harmful to cardiopulmonary resuscitation. Although most manual resuscitator seem to follow international standards, the equipment must be evaluated in the clinical settings. There are few studies about pediatric and neonatal manual resuscitator models.
