在本研究中，72名儿童在腹部x线摄影之前，通过测量CO2和pH值以及管吸出物的胆红素来确定鼻胃/口胃管的内部位置。72根试管中有15根（20.8%）在x线片上放置不正确。使用建议的成人临界值pH 5，吸出液的pH值正确预测7/28（25%）儿童胃外的错误放置，正确预测40名儿童中34名（85%）儿童胃内的正确放置。使用建议的成人切断胆红素>或= 5mg /dL，胆红素监测未能识别两个放置不正确的管。在本研究中，如果抽吸液的pH值<或= 5，使用假设胃位置的算法，当没有抽吸液或pH值为bbb50时进行腹部x线片检查，准确率将达到92%。另外，获得腹部x光片将获得接近100%的准确性。
In this study, the internal position of a nasogastric/orogastric tube was determined in 72 children, prior to an abdominal radiograph, by measuring CO2 and pH and bilirubin of tube aspirate. Fifteen of the 72 tubes (20.8%) were incorrectly placed on radiograph. Using the suggested adult cutoff of pH 5, pH of aspirate correctly predicted misplacement outside the stomach in 7/28 (25%) of children and correctly predicted correct placement in the stomach in 34 of 40 children (85%). Using the suggested adult cutoff of bilirubin > or = 5 mg/dL, bilirubin monitoring failed to identify either of two incorrectly placed tubes. In this study, using an algorithm of assuming stomach placement if the pH of aspirate is < or = 5 and obtaining an abdominal radiograph when either no aspirate is obtained or the pH is >5 would have resulted in 92% accuracy. Alternatively, obtaining an abdominal radiograph would result in nearly 100% accuracy.
