The objective of this study was to test the inter-rater reproducibility of the Portuguese version of the PEDro Scale. Seven physiotherapists rated the methodological quality of 50 reports of randomized controlled trials written in Portuguese indexed on the PEDro database. Each report was also rated using the English version of the PEDro Scale. Reproducibility was evaluated by comparing two separate ratings of reports written in Portuguese and comparing the Portuguese PEDro score with the English version of the scale. Kappa coefficients ranged from 0.53 to 1.00 for individual item and an intraclass correlation coefficient (ICC) of 0.82 for the total PEDro score was observed. The standard error of the measurement of the scale was 0.58. The Portuguese version of the scale was comparable with the English version, with an ICC of 0.78. The inter-rater reproducibility of the Brazilian Portuguese PEDro Scale is adequate and similar to the original English version.

JUSTIFICATIVA E OBJETIVOS: O desmame da ventilação mecânica é o processo de transição da ventilação mecânica para a espontânea. A prática atual do desmame mostra que o empirismo é insuficiente e inadequado. Em contrapartida, as padronizações de desmame proporcionam melhor condução no processo. O objetivo deste estudo foi avaliar os efeitos da aplicação de um protocolo de desmame da ventilação mecânica em uma unidade de terapia intensiva. MÉTODO: Foram incluídos no estudo todos os pacientes em programa de liberação da ventilação mecânica, em que se acompanhou a evolução do desmame com utilização de um protocolo pré-estabelecido pelo serviço já publicado. RESULTADOS: Foram estudados 127 pacientes. Houve sucesso no desmame em 91% (115) e insucesso em 9% (12). A ventilação não-invasiva após a extubação foi utilizada em 19% (24) deles. Nenhum óbito foi observado. Comparando-se o grupo de pacientes em que houve sucesso com o grupo em que houve falha, não foi encontrada diferença estatística significativa quanto ao sexo (p = 0,96), APACHE II (19,5 versus 18,6 p = 0,75), risco de óbito (29% versus 22% p = 0,54), Pimáx (38 versus 32 cmH2O p = 0,17), tempo de ventilação mecânica (6 versus 7 dias p = 0,70), relação PaO2/FiO2 (324 versus 312 p = 0,83), modalidade de desmame (PSV ou Tubo T p = 0,29). Foram encontradas diferenças significativas no valor de índice de respiração rápida superficial (IRRS) (59 versus 77 p = 0,02) e no tempo de desmame (1 versus 30 horas p < 0,001). CONCLUSÕES: O desmame da ventilação realizado seguindo a padronização trouxe melhora na sua condução, mantendo o alto índice de sucesso com baixa mortalidade.BACKGROUND AND OBJECTIVES: The weaning of mechanical ventilation is the process of transition from mechanical ventilation to spontaneous. The actual practice weaning reveals that the empirism is insufficient and inadequate. On the other side, the standardization of the weaning provides best conductions in the process. The objective of this study was to evaluate the effects of the application of a weaning protocol in an intensive care unit. METHODS: Method: It was included in this study all the patients in program of liberation from the mechanical ventilation, in which the evolution of the weaning was followed by the utilization of a pre-establish protocol and publicated by the service. RESULTS: It was studied 127 patients. In 91% (115) of the patients we had success in the weaning and unsuccess in 9% (12). The non-invasive ventilation after the extubation was utilized in 19% (24) of them. None obit was observed. Comparing the group of the patients that had success with the failed group, there were no statistically significant variations observed in sex (p = 0.96), APACHE II (19.5 versus 18.6 p = 0.75), risk of obit (29% versus 22% p = 0.54), MIP (38 versus 32 cmH2O p = 0.17), duration of mechanical ventilation (6 versus 7 days p = 0.70), PaO2/FiO2 relation (324 versus 312 p = 0.83), weaning modality (PSV or T Tube p = 0.29). There were statistically significant variations observed in rapid shallow respiratory index (59 versus 77 p = 0.02) and duration of the weaning (1 versus 30 hours p < 0.001). CONCLUSIONS: The weaning of the ventilation realized following the standardization brought improvement in its conduction, maintaining the high success index with low mortality.
