The breath hydrogen test is used in gastroenterological investigation, particularly for sugar malabsorption, transit time, and the investigation of small-bowel bacterial overgrowth. Several methods of collecting breath from infants and children for hydrogen assay have been described. Four such techniques (postnasal catheter, nasal prong, Rahn-Otis end-tidal sampler, and modification of a party toy--the 'Wiggins's blowout') were compared with breath collection using the Haldane-Priestley tube. Multiple sampling of breath from 3 adults was performed after initial lactulose loads to increase breath hydrogen excretion. The variability between the different assay techniques was less than the inherent variability of repeated breath hydrogen assays using the same technique. Each technique is therefore adequate for breath hydrogen collection; we recommend the Rahn-Otis end-tidal sampler in young infants and children, and the Haldane-Priestley tube in older children, since these were most acceptable to the children and their parents.
呼气氢试验用于胃肠病学检查，特别是用于检测糖吸收不良、通过时间以及小肠细菌过度生长情况。已有多种从婴幼儿收集呼气进行氢分析的方法被描述。将四种此类技术（鼻后导管、鼻叉、Rahn-Otis潮气末采样器以及一种派对玩具的改良版——“威金斯吹气器”）与使用霍尔丹-普里斯特利管收集呼气进行了比较。在最初给予乳果糖负荷后，对3名成年人进行了多次呼气采样以增加呼气氢排泄量。不同检测技术之间的变异性小于使用相同技术进行重复呼气氢检测的固有变异性。因此，每种技术都足以用于收集呼气氢；我们建议在幼儿和儿童中使用Rahn-Otis潮气末采样器，在大龄儿童中使用霍尔丹-普里斯特利管，因为这些对儿童及其父母来说是最容易接受的。
