New equipment developed at HCPA for otologic surgery (microcautery) : Part I - technical specifications

Este artigo apresenta a descrição de um microcautério otológico com dispositivos de aspiração e descolamento para utilização em cirurgia otológica. O microcautério foi desenvolvido no Hospital de Clínicas de Porto Alegre, pelos setores de Engenharia Biomédica e Otorrinolaringologia.This article presents the description of an otologic microcautery with aspiration and detachment devices to be used in otologic surgery.

Dyspnea perception during the inspiratory resistive loads test in obese subjects waiting bariatric surgery

Identifcation of low dyspnea perception is relevant, since this condition is signifcantly associated with worse outcomes. We investigated dyspnea perception during the inspiratory resistive loads test on obese subjects waiting bariatric surgery in comparison with normal subjects. Secondarily, we analysed the proportion of obese subjects with low, moderate and high dyspnea perception. This observational study included subjects with body mass index (BMI)≥35kg/m2, compared to healthy subjects with BMI ≥18 and <25kg/m2. Subject underwent clinical evaluation, inspiratory test with progressive resistive loads and spirometry. We studied 23 obese subjects (mean BMI=51.9±9.3kg/ m2) and 25 normal subjects (mean BMI=24.3±2.3kg/m2). With the increase magnitude of resistive loads there was a signifcant increase in dyspnea score (p<0.001) and progressive increase of the generated inspiratory pressure (p<0.001), but there was no diference between the groups in terms of dyspnea score (p=0.191) and no interaction efect (p=0.372). Among the obese subjects, 4 individuals were classifed as low perception, 11 as moderate and 8 as high. In conclusion, the degree of dyspnea perception during the inspiratory progressive resistive loads test did not difer between obese and normal subjects. Among obese subjects, only 17% were classifed as low dyspnea perception

New equipment for otologic surgery developed at HCPA (microcautery) : part II - study in human beings

OBJETIVO: Descrever a avaliação, em cirurgias de ouvido médio em seres humanos, do microcautério otológico Lavinsky/HCPA. MATERIAIS E MÉTODOS: Vinte e quatro pacientes com indicação para estapedectomias e timpanoplastias unilaterais ou bilaterais foram selecionados. Foram excluídos pacientes com doenças sistêmicas, como hipertensão arterial sistêmica não controlada e discrasia sangüíneas. Os pacientes foram divididos em dois grupos: 12 foram operados com o microcautério e 12, sem. As cirurgias foram gravadas em vídeo e avaliadas por dois cirurgiões otológicos, cegos para o tipo de procedimento utilizado. Os resultados foram qualificados como ótimo, bom, regular ou ruim. O parâmetro utilizado na avaliação foi hemostasia. RESULTADOS: Os avaliadores qualificaram como ótimo o resultado global de todas as cirurgias realizadas com o microcautério. No grupo controle, um avaliador qualificou 42% das cirurgias como ruim e 58% como regular. CONCLUSÕES: O uso do microcautério demonstrou benefícios concretos em comparação com métodos convencionais.OBJECTIVE: To describe the evaluation, in middle ear surgeries in human beings, of the Lavinsky/HCPA otologic microcautery . MATERIALS AND METHODS: Twenty-four patients with indication for unilateral or bilateral stapedoctomies and tympanoplasties were selected. Patients presenting systemic diseases, non controlled systemic arterial hypertension and blood dyscrasia were excluded. Patients were divideded into two groups: 12 were operated with the microcautery and 12 without it. Surgeries were videotaped and evaluated by two otologic surgeries, blind to the kind of procedure used. Surgeries were classified as excellent, good, regular and poor. Hemostasis was the parameter considered in the evaluation. RESULTS: The evaluators considered as excellent the overall outcome of all surgeries performed with the microcautery. In the control group, one evaluator qualified 42% of surgeries as poor and 58% as regular. CONCLUSIONS: The utilization of the microcautery had concrete benefits in comparison with conventional methods
