Edema agudo do pulmão pós-extubação traqueal â Caso clínico

Abstract

Resumo: O edema agudo do pulmão pós-extubação traqueal é um acontecimento raro (â 0,1%)1. A etiologia é multifactorial, sendo a obstrução da via aérea superior o factor desencadeante principal. O esforço inspiratório contra a glote encerrada causa pressões intratorácicas muito negativas, que se transmitem ao interstício pul-monar, condicionando uma transudação de fluidos a partir dos vasos capilares pulmonares1â5. Relatamos um caso de edema agudo do pulmão pós-extubação num doente de quinze anos, operado no serviço de urgência por amputação traumática da perna esquer-da. Revemos a fisiopatologia, o padrão radiológico, potenciais factores de risco e medidas preventivas des-ta complicação respiratória pós-anestésica.Rev Port Pneumol 2009; XV (3): 537-541 Abstract: Negative pressure pulmonary oedema is an uncommon complication of traqueal extubation (â 0,1%) mostly caused by acute upper airway obstruction. Upper airway obstruction from glottis closure leads to marked inspiratory effort, which generates negative intrathoracic pressure transmitting to pulmonary interstitium, and inducing fluid transudation from pulmonary capillary bed1â5. We report a case of post-extubation pulmonary oedema in a fifteen years old patient, submitted to surgery following traumatic amputation of his left leg. We review the pathophysiology, radiological findings, potential risk factors and preventive measures of this post-anaesthetic respiratory complication.Rev Port Pneumol 2009; XV (3): 537-541 Palavras-chave: Edema agudo do pulmão pós-extubação traqueal, obstrução da via aérea superior, laringospasmo, pressão negativa intratorácica, Key-words: Post-extubation pulmonary oedema, upper airway obstruction, laryngospasm, intra-thoracic negative pressure
