ABSTRACT
ABSTRACTINTRODUCTION:Flexible fiber optic bronchoscopy is a valuable intervention for evaluation and management of respiratory diseases in both infants, pediatric and adult patients. The aim of this study is to investigate the influence of the airway supporting maneuvers on glottis view during pediatric flexible fiberoptic bronchoscopy.MATERIALS AND METHODS:In this randomized, controlled, crossover study; patients aged between 0 and 15 years who underwent flexible fiberoptic bronchoscopy procedure having American Society of Anesthesiologists I---II risk score were included. Patients having risk of difficult intubation, intubated or patients with tracheostomy, and patients with reduced neck mobility or having cautions for neck mobility were excluded from this study. After obtaining best glottic view at the neutral position, patients were positioned jaw trust with open mouth, jaw trust with teeth prottution, head tilt chin lift and triple airway maneuvers and best glottis scores were recorded.RESULTS:Total of 121 pediatric patients, 57 girls and 64 boys, were included in this study. Both jaw trust with open mouth and jaw trust with teeth prottution maneuvers improved the glottis view compared with neutral position (p < 0.05), but we did not observe any difference between jaw trust with open mouth and jaw trust with teeth prottution maneuvers (p > 0.05). Head tilt chin lift and triple airway maneuvers improved glottis view when compared with both jaw trust with open mouth and jaw trust with teeth prottution maneuvers and neutral position (p < 0.05); however we found no differences between head tilt chin lift and triple airway maneuvers (p > 0.05).
RESUMOINTRODUÇÃO: A broncofibroscopia flexível (BF) é uma valiosa intervenção para o manejo eavaliação de doenças respiratórias em pacientes tanto pediátricos quanto adultos. O obje-tivo deste estudo foi investigar a influência das manobras de apoio das vias aéreas sobre avisibilidade da glote durante a BF pediátrica.MATERIAL E MÉTODO: Estudo cruzado, randômico e controlado, incluindo pacientes com idadesentre 0-15 anos, ASA I-II, que foram submetidos à BF. Pacientes com risco de intubação difí-cil, entubados ou com traqueostomia e aqueles com mobilidade reduzida do pescoço ou queexigissem cuidados para a mobilidade do pescoço foram excluídos do estudo. Depois de obter amelhor visibilidade da glote na posição neutra, os pacientes foram posicionados com elevaçãoda mandíbula e abertura da aberta (EMBA), com elevação da mandíbula e protrusão dos dentes(EMPD), com inclinação da cabeça elevação do queixo (ICEQ) e com a tripla manobra das viasaéreas (TMVA). Os melhores escores da glote foram registrados.RESULTADOS: No total, 121 pacientes pediátricos foram incluídos no estudo: 57 pacientes do sexofeminino e 64 do sexo masculino. Ambos as manobras EMBA e EMPD melhoraram a visibilidadeda glote em comparação com a posição neutra (p < 0,05), mas não observamos diferença entreas manobras EMBA e EMPD (p > 0,05). As manobras ICEQ e TMVA melhoraram a visibilidade daglote em comparação com as manobras EMBA e EMPD e a posição neutra (p < 0,05); porém, nãoencontramos diferenças entre a ICEQ e a TMVA (p > 0,05).CONCLUSÃO: Todas as manobras de acesso às vias aéreas melhoraram a visibilidade da glotedurante a BF pediátrica; porém, a inclinação da cabeça e elevação do queixo e a tripla manobradas vias aéreas foram consideradas as manobras mais eficazes.

Certain occupational groups are known to be at particularly high risk of developing allergic diseases. The objective of the present study was to evaluate the prevalence of allergic diseases among working adolescents. The International Study of Asthma and Allergies in Childhood questionnaire was used. Four hundred and thirty six adolescents working in motor, lathe-finish, coiffure and textile and 366 high school students as control group were enrolled to the study. Mean age was 16.8 ± 1.2 years and 82.9% of them were male. There was no significant difference among groups for ever and current wheezing while doctor diagnosed asthma was higher in lathe- finish group (p = 0.036). Family history of allergy, history of allergic rhinitis, and active smoking were found to be risk factors for asthma and related symptoms. Working in coiffure (p = 0.054), and textile (p = 0.003) were significant risk factors for ever allergic rhinitis. Working in lathe finish (p = 0.023), coiffure (p = .002), and textile (p < 0.001) were associated with a higher risk for current allergic rhinitis. Working in coiffure was a risk factor for ever eczema (p = 0.008) and doctor diagnosed eczema (p = 0.014). It was concluded that working in lathe-finish was associated with doctor diagnosed asthma and active smoking was a risk factor for asthma and related symptoms. Working in coiffure, textile and lathe- finish were risk factors for rhinitis, and working in coiffure was a risk factor for eczema. Preventive measures should be taken at the onset of employment in order to prevent or reduce the detrimental effects of exposures in these occupational groups.
