Abstract: Objective:To observe the anesthetic effects of fiberoptic bronchoscopy positioning supreme laryngeal mask airway(SLMA) in kidney operation with lateral position.Methods:Sixty patients with ASA Ⅰto Ⅱ treated with lateral position kidney operation were randomly divided into SLMA group(30 cases) and tube intubation group(TT group, 30 cases).The levels of MAP, HR and P_ETCO₂ were observed after intubation tube under anesthesia.The success rates of the first and second intubation, anesthetic complications and extubation response were recorded.Results:The success rates of the first and second intubation in SLMA group were 90.0% and 100.0%, respectively.The changes of MAP and HR levels at all time-points were not significant in SLMA group(P>0.05), the levels of MAP and HR at T₂ to T₅ time-points were significantly higher than those in T₁ time-point in TT group(P<0.01).The increasing of MAP in T₂ to T₅ time-points and HR in T₂ to T₄ time-points in TT group were higher than those in SLMA group(P<0.05 to P<0.01).The cough and airway complications in 24 hours in SLMA group were less than those in TT group(P<0.05).Conclusions:The fiberoptic bronchoscopy positioning SLMA can be safely used in the anesthetic management of kidney operation with lateral position.
