Abstract

The mode of anaesthesia used during pneumoencephalography has a significant effect on the size of the cerebral ventricles 24 hours after the procedure. Post-encephalographic ventricular enlargement is less marked in patients examined under nitrous oxide anaesthesia. This appears to be related to passage of the gas into the ventricles during the encephalogram, and subsequent diffusion outwards. Variations in arterial carbon dioxide tension during the anaesthesia do not contribute significantly to changes in ventricular size. However, both hyperventilation and inhalation of nitrous oxide may cause apparent increase in size of the cerebral sulci.

摘要

气脑造影术中所采用的麻醉方式对术后24小时脑室大小有显著影响。在氧化亚氮麻醉下接受检查的患者,造影后脑室扩大情况不太明显。这似乎与气脑造影过程中气体进入脑室以及随后向外扩散有关。麻醉期间动脉血二氧化碳张力的变化对脑室大小的改变影响不大。然而,过度通气和吸入氧化亚氮均可导致脑沟大小明显增加。
