摘要
目的比较喉罩和气管插管对老年冠心病患者血流动力学、呼吸功能和应激激素的影响。方法32例老年冠心病患者ASAⅡ级在全麻下实施胃肠手术,随机均分为喉罩组和气管内插管组。在麻醉诱导前(T0)、插入喉罩/气管导管前(T1)、插入喉罩/气管导管后即刻(T2)、插入喉罩/气管导管后5min(T3)、10min(T4)、15min(T5)和切皮时(T6)、拔管后即刻(17)记录SBP、DBP、HR。应用BICORE呼吸功能监测仪监测呼吸功能16项指标,选择T0、T3、T4、T5、T7时记录吸气潮气量(,VTI)、呼气潮气量(VTE)、分钟通气量(VE)、吸气峰流速(PIFR)、呼气峰流速(PEFR)、吸气峰压(P1P)和平均气道阻力(RAWM)。每组患者于T0、T1、他、T6、丌时应用高效液相色谱分析法测定血浆肾上腺素(AE)、去甲肾上腺素(NE)、多巴胺(DA)水平。结果气管插管组T2时SBP、DBP、HR显著高于喉罩组(P〈0.05);VTI、VTE、VE、PIFR、PEFR、PIP和RAWM组间差异无统计学意义,AE、NE、DA在T2、T7时均显著高于喉罩组(P〈0.05)。结论全麻喉罩通气用于老年冠心病患者优于气管插管,易于维持血流动力学稳定,应激反应轻微,全麻后恢复平稳。
Objective to compare the LMA and intubation in elderly patients with coronary heart disease hemodynamics, respiratory function and the impact of stress hormones. Methods 32 cases of elderly patients with coro- nary 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 (TO) , insert the LMA / endotraeheal tube before ( T1 ) , insert the LMA / tracheal tube immediately after (T2) , insert the LMA / endotracheal tube after 5 min (T3) , 10 min (T4) , 15 min (TS) and the skin incision, (T6) , immediately after extubation (T7) record SBP, DBP, HR. Application BICORE monitor respiratory function 16 indicators, select TO, T3, T4, TS, 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 TO, T1, T2, T6, T7 at the application of high performance liquid 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 hemodynamics, the stress response minor, after the restoration of a smooth general anesthesia.
