The frequency of side effects and complications from aqueous myelography is increased by dehydration. To study the effect of dehydration on the elimination of water-soluble contrast medium from the lumbar subarachnoid space, we measured iodine concentrations in the cerebrospinal fluid, serum, and urine for 24 hours after myelography in "hydrated" and "dehydrated" monkeys. Dehydrated animals were fasted for 12 hours prior to and 24 hours after myelography; hydrated animals received oral fluids ad libitum and 300 ml of intravenous fluids. Dehydrated animals had a lower concentration of contrast medium in the blood than hydrated animals. Dehydration slows the elimination of aqueous contrast medium from the lumbar subarachnoid space.
脱水会增加水溶性脊髓造影的副作用和并发症的发生率。为了研究脱水对水溶性造影剂从腰蛛网膜下腔清除的影响，我们在“水合”和“脱水”的猴子进行脊髓造影后24小时测量了脑脊液、血清和尿液中的碘浓度。脱水的动物在脊髓造影前12小时和后24小时禁食；水合的动物随意口服液体并静脉输注300毫升液体。脱水动物血液中的造影剂浓度低于水合动物。脱水会减缓水溶性造影剂从腰蛛网膜下腔的清除。
