摘要:
目的:机械通气时气道压力的增高对自主神经系统(ANS)产生诸多负面影响,破坏脏器功能的稳定。本研究探讨常规的择期全麻手术中不同的机械通气压力对ANS活动性的影响。方法:选择择期行骨科手术患者32例,术中连续采集心电信号,于术中麻醉和手术平稳阶段将机械通气先后设置为:低气道压模式持续20 min;高气道压模式持续20 min,分别记录潮气量(Vt)、气道峰压(PIP)、平均气道压(Pm)等各项机械通气指标。截取诱导前(T0)、术中平稳时(T1)、低气道压(T2)、高气道压(T3)各5 min心电信号行心率变异性(HRV)分析,同时比较血流动力学指标。结果:T3时血流动力学指标HR、MAP较T2时无明显变化(P>0.05)。T3时机械通气参数Vt、PIP、Pm与T2时相比均明显增大(P<0.05);呼气末二氧化碳分压(PETCO2)则较T2时降低(P<0.05)。T3时HRV指标RMSSD、SDNN、LgTP、LgHF、LgLF、SD1、SD2、DC与T2时相比均无明显差异(P>0.05)。结论:维持一定的麻醉深度并保持PETCO2在正常范围内时,对于常规的全麻择期手术患者,增加机械通气时的气道压力对自主神经无明显影响。
