Comparison of SLIPA Laryngeal mask airway and endotreacheal intubation in general anesthesia of breast cancer modified radical mastectomy

Objective To observe the effects of SLIPA laryngeal mask airway and endotreacheal intubation on hemodynamics of breast cancer modified radical mastectomy.Methods Eighty patients scheduled for selective breast cancer modified radical mastect,my under general anesthesia,were randomized into two groups with 40 cases each:SLIPA (S) group and endotreacheal intubation (T) group.SBP,DBP,HR and SpO2 were recorded at 6 time points:before intubution (T1),at the time of intubation (T2),3 min (T3) after intubation,before extubation (T4),at the time of extubation (T5),3 min (T6) after extubation.SpO2,PETCO2,peak airway pressure (Ppeak) were monitored at T2-T4.Intraoperative aspiration of reflux and postoperative throat complications were observed.Results In group T,SBP,DBP and HR at T2,T4,T5 were higher than those at T1 and at the same time points in group S (P ＜ 0.05) ; In group S,after pulling out laryngeal mask,the incidences of hypoxemia and throat discomfort were lower than those in group T(P ＜ 0.05) ;And no cough cases; Intraoperative SpO2,PETCO2,and Ppeak were within the normal ranges in the two groups.There was no occurrence of reflux aspiration.Conclusions SLIPA larngeal mask airway induces less stress reaction and has fewer complications of throat after operation in patients underwent breast cancer modified radical mastectomy.
