THE STUDY OF COMPERATION OF LARYNGEAL MASK AIRWAY SUPREME AND ENDOTRACHEAL INTUBATION USED WITH THE ELDERLY PATIENTS UNDERGOING RADICAL MASTECTOMY

Objective:To compare the effects and safety of laryngeal mask airway supreme and endotracheal intubation in the elderly patients undergoing radical mastectomy.Methods:Eighty patients with breast cancer undergoing selective mastectomy were randomly divided into two grups with 40 cases each.The patients in group L were ventilated with laryngeal mask and those in group T were given conventional tracheal intubation as the controls.Patients'SBP,DBP,HR,SpO2,PETCO2 and Ppeack were recorded before the induction of general anesthesia(T0),before inserting laryngeal mask airway/tracheal tube(T1),inserting laryngeal mask airway/tracheal tube immediately(T2),after inserting laryngeal mask airway/tracheal tube 1 min(T3),3 min(T4),5min(T5),uprooting laryngeal mask airway/tracheal tube immediately(T6),The complications of anesthesia were recorded included bucking,countercurrent,aspiration and postoperative pharyngolaryngeal adverse events during each operation.Results:Compared with the T group,L group laryngeal mask insert a high success rate(P0.05),insert a short time(P0.01).The SBP,DBP of the two groups patients at T1 was significantly lower than T2(P0.05),T group patients T2.T3 and T6 point of the SBP,DBP and HR significantly increased compared with T0(P0.05),the SBP,DBP and HR of group L patients T2.T3 point significantly lower than in group T(P0.05),the SBP and HR of group L patients T6 point significantly lower than in group T(P0.05),The patients' hypoxemia during extubation and postoperative sore throat in group L were found significantly lower than those in group T(P0.01).SpO2,PETCO2 and Ppeack in the two groups of patients are within the normal range,and less than absorption occurred.Conclusion: Supreme laryngeal mask airway are not only hemodynamic relatively stable but also reduce the perioperative associated complications,whose advantages are obviously higher than endotracheal tube.
