Perioperative pulmonary aspiration prophylaxis

Emily L. Wang, Jeffrey Lu

Research output: Chapter in Book/Report/Conference proceedingChapter


Pulmonary aspiration: the regurgitation of gastric contents with subsequent entry into the respiratory tract, which can cause acute lung injury. Particulate matter in the aspirated contents may lead to a focal inflammatory and foreign-body reaction. Pulmonary injury includes aspiration pneumonitis, which can later evolve into aspiration pneumonia, respiratory failure, or acute respiratory distress syndrome (ARDS).
