RESUMO
JUSTIFICATIVA E OBJETIVOS: O desmame da ventilação mecânica é um desafio na prática da unidade de terapia intensiva (UTI) e está relacionado a diversas complicações. Uma dessas complicações relaciona-se ao laringoespasmo pós-extubação, evento que muitas vezes pode ser previsto através do teste de escape do balonete (TEB). O objetivo deste estudo foi demonstrar que o TEB é um método simples, confiável e de baixo custo para avaliar o grau de obstrução de via aérea superior em pacientes no processo de desmame da ventilação mecânica. CONTEÚDO: Foi realizada revisão sistemática da literatura através das bases de dados MedLine, SciElo e LILACS com publicações entre 1995 e 2007. Os artigos incluídos abordaram o uso do teste do balonete como índice preditivo para laringoespasmo e falha na extubação traqueal. Não fizeram parte estudos com animais e revisões bibliográficas. Procurou-se relacionar o TEB com tempo de ventilação mecânica, idade e grupos específicos de pacientes que se beneficiaram com a técnica. CONCUSÕES: O TEB pode ser considerado bom índice preditivo para identificar a presença de laringoespasmo pós-extubação, quando levadas em consideração as características da população estudada.
BACKGROUND AND OBJECTIVES: Weaning patients from mechanical ventilation is a challenge in the intensive care unit (ICU) practice and is related to some complications. One of these is the pos-extubation laryngospasm, an event that can be anticipated for the cuff leak test (CLT). The objective was demonstrate that the CLT is a simple, reliable and low costs method to available the presence of obstruction in high airway in patients under weaning ventilator. CONTENTS: It was made a systematic review in databases MedLine, SciElo and LILACS with articles from 1995 to 2007. The selected studies focused the use of the CLT to predict laryngospasm and extubation failure. It was excluded studies with animals and others literature reviews. It was looked correlates the CLT with mechanical ventilation's days, age and specific groups that could beneficiates with the application of this technique. CONCLUSIONS: The CLT can be considerate a good index to predict laryngospasm pos-extubation, when considerate the studied population characteristics.
