【摘要】 目的:观察两种麻醉方法对患者呼吸功能的影响。方法:国产麻醉呼吸机功能仪检测10例肌间沟入路和8例锁骨上入路臂丛神经阻滞患者麻醉前后的通气功能。结果:患者肺活量(VC)、用力肺活量(FVC)及1秒钟时间的肺活量(FEV1)均有显著下降(P<0.05),其下降幅度与文献报道中由于单侧隔肌麻痹引起通气功能幅度相近。结论:此两种麻醉方法均可阻滞膈神经而导致单侧膈肌麻痹,引起通气功能降低。因此,并发心肺疾患、呼吸代偿能力低下或麻醉中应慎用强力镇静药,以避免进一步加重呼吸抑制。更多还原

【Abstract】 Objective:To detect the effects of inerscaleneand superclavical brachial plexus block on respiratory function.Merthods:The respiratory function of ten patients anesthesized with inerscalene brachial plexus block and that of eight patients withssuperclaavicalsbrachialplesusblockweretested.Results:Thevitalcapacity(VC),forced vi-tal capacity(FVC) and force expiratory volume(FEV) were reduced significantly(P<0.05) following anesthesia-a.Conclusion:Interscalene and superclavical brachial plexus blocks are sate to the normal patients but are dangerous to those suffering from serious lung and chest diseases.更多还原
