斜角肌间沟和锁骨上入路臂丛阻滞对通气功能的影响

Interscalene and superclavical brachial plexus blocks affect respiratory function

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。

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