Perioperative airway management is a top priority of anesthesiologists in daily work, and endotracheal intubation (ETI) is considered as the gold standard for providing safe glottic seal,effective ventilation and oxygen supplement during general anesthesia. But ETI related complications such as concomitant hemodynamic responses, damage to the oropharyngeal structures at insertion and postoperative sore throat. Laryngeal mask airway(LMA) for the anesthesia management brings new choice with invasive, lighter cardiovascular reaction and many other advantages, particularly suited to short and minimally invasive surgery. But LMA increased the risk of gastrointestinal reflux aspiration than using ETI and it may resulted in intolerance in high airway pressure, especially in elderly patients with increased lung compliance or reduced airway resistance. Furthermore, LMA could not entirely prevent the occurrence of postoperative sore throat and hoarse. To sum up, it is necessary to carry out a multicenter clinical trial to clarify the safety of LMA in elderly patients. The investigators protocol will focus on the incidence of postoperative pulmonary complications (PPCs) when applications of LMA and ETI in elderly patients.
