Abstract:
Objective to compare the LMA and intubation in elderly patients with coronary heart disease hemedynamics,respiratory function and the impact of stress hormones.Methods 32 cases of elderly patients with coronary heart disease ASA II level under general anesthesia in the implementation of gastrointestinal surgery,were randomly divided into LMA group and endotracheal intubation group.Before the induction of anesthesia (T0),insert the LMA/endotracbeal tube before(T1),insert the LMA/tracheal tube immediately after(T2),insert the LMA/endotracbeal tube after 5 min(T3) ,10 min(T4),15 min(T5) and the skin incision,(T6) ,immediately after extubation (T7) record SBP,DBP,HR.Application BICORE monitor respiratory function 16 indicators,select T0,T3,T4,T5,T7 record at the suction tidal volume (,VTI),breath tidal volume (VTE),minute ventilation (VE),Inspiratory peak velocity(PIFR),peak expiratory flow rate (PEFR) ,peak inspiratory pressure(PIP) and the average airway resistance (RAWM).Patients in each group T0,T1,T2,T6,T7 at the application of high performance Iiqnid chromatography analysis of plasma epinephrine(AE),norepinephrine(NE),dopamine (DA) level.Results intubation group T2 at the SBP,DBP,HR significantly higher than the LMA group (P＜0.05) ;,VTI,VTE,VE,PIFR,PEFR,PIP and RAWM group there was no significant difference,AE,NE,DA in T2,T7,were significantly higher than the LMA group (P＜0.05).Conclusion Laryngeal Mask Airway general anesthesia for elderly patients with coronary heart disease is better than intubation,easy to maintain stable bemedynamics,the stress response minor,after the restoration of a smooth general anesthesia.
