A comment on- 'positive end-expiratory pressure as a novel method to thwart CO2leakage from capnothorax in robotic-assisted thoracoscopic surgery'

摘要

I read, with great interest thecasereport— 'positiveend-expiratory pressureasa novelmethod to thwart CO2 leakagefromcapnothorax in robotic-assistedthoracoscopicsurgery' byRaviRetal.[1] According to authors, reported events occurred dueto leakage ofcarbon dioxide(CO2) gas fromthe pleuralcavity into thetracheathrough arent in theleft lower lobe bronchus. However, this is unlikely ifArndtendobronchial blocker (Cook? Medical) was placed in theleftmain bronchusand wasadequately inflated. In thecase, Ravietal. had notmentioned the volume withwhich the bronchialcuff ofthe blocker was inflated. The bronchialcuff of 7 FArndt blocker takes 2-6 cc ofair foradequateinflation.
