The authors give their experiences in nurseling and children brain neuroradiology anaesthesia. Sodium gammahydroxybutyrate has been definitively adopted after multiples anaesthesial protocoles for the gaz tomoencephalographic exam, known for its technical risks. The gamma OH gives a perfect cardiac and pulmonary stability in difficult conditions, with normal intracranial pression, even in children anaesthesia with Halothane (0.5%) for complementary analgesic effect or with fractionate injections of dextromoramide. Pneumoencephalography has been releguated in second place by the even of brain computer tomography except some particular indications. But this exam qualified as painless is usually indicated in fragile and deficient childrens. Though the intravenous iodated contrasted substance injection can improve the scan image quality and may induce secondary effects at 2 cm3/kg dose. It's again gamma OH after correct premedication that gives stable, perfect immobility, cardiac and pulmonary stability in an ideal anaesthesia for non ventilated patients. The only critical aspect of this method consists on a prolonged and imprevisible delay to awake so that it cannot be an ambulatory anaesthesial method. Therefore it appears that gamma OH in spite of brain computer tomographic event, is an interesting anaesthesic drug but non definitive in brain neuroradiological exam for childrens.
作者介绍了他们在婴儿和儿童脑神经营放射学麻醉方面的经验。在经历了多种用于气脑造影检查的麻醉方案（该检查以技术风险著称）后，γ-羟基丁酸钠已被明确采用。γ-OH在困难情况下能提供完美的心肺稳定性，颅内压正常，即使是在使用氟烷（0.5%）进行儿童麻醉以获得辅助镇痛效果或分次注射右吗拉胺的情况下。除了一些特殊指征外，脑计算机断层扫描的出现已使气脑造影退居其次。但这项被认为无痛的检查通常适用于体弱和有缺陷的儿童。尽管静脉注射碘化造影剂可以提高扫描图像质量，且在2立方厘米/千克的剂量下可能会引起副作用。在正确的术前用药后，同样是γ-OH能在非通气患者的理想麻醉中提供稳定、完美的不动状态以及心肺稳定性。这种方法唯一关键的方面在于苏醒延迟时间长且不可预测，因此它不能作为一种门诊麻醉方法。所以，尽管有脑计算机断层扫描的出现，γ-OH似乎仍是一种有趣的麻醉药物，但在儿童脑神经营放射学检查中并非绝对适用。
