Application of Proseal laryngeal mask airway during anesthesia of gynecologic oncologic surgery

Objective To investigate the safety and feasibility of Proseal laryngeal mask airway (PLMA) in the anesthesia of gynecologic oncologic surgery, and to compare with traditional endotracheal intubation(ETT). Methods Sixty patients undergone selective gynecologic oncologic surgery were randomly allocated to PLMA group and ETT group. The insertion time, number of attempts, intraoperative peak airway pressure, blood pressure (BP), heart rate (HR) and anesthesia complications were recorded. Results The insertion time of PLMA group was longer than that of ETr group [(48.6±9.3)s vs (22.4±5.9)s, P 0.05). In PLMA group, BP and HR did not change significantly after inserting the PLMA , while in ETT group, BP and HR increased significantly after inserting the ETT (P< 0.05). The incidence of coughing, bucking, body movement at recovery and postoperative 3 h sore throat of PLMA group [6.7%(2/30), 10.0%(3/30)] was significantly lower than those of ETT group[46.7%( 14/30), 33.3% (10/30)] (P<0.05). Conclusion PLMA can be used safely and effectively in the anesthesia of gynecologic oncologic surgery.
