The changes in plasma electrolytes and blood pH and gases following the insufflation of air into the subarachnoid space for pneumoencephalography were investigated. The only significant change observed was a rapid fall of plasma potassium most evident at 60 minutes. A concomitant reduction of the urinary Na/K ratio supports the possibility that the change observed may be due to the stimulation of aldosterone secretion caused by this procedure, though its rapid occurrence and reversibility indicate that other influences might at least in part be responsible.
对气脑造影术中向蛛网膜下腔注入空气后血浆电解质、血液pH值及气体的变化进行了研究。观察到的唯一显著变化是血浆钾迅速下降，在60分钟时最为明显。尿钠/钾比值的相应降低支持了以下可能性：观察到的变化可能是由于该操作刺激醛固酮分泌所致，尽管其快速发生和可逆性表明其他影响因素可能至少部分起了作用。
