摘要

这项前瞻性、随机、方便的研究的临床目的是:1。比较一种新型光纤pH测试装置(NGPOD)与胃吸液和鼻胃管(NGT)确认的pH测试。2. 确定新设备是否减少了胸部x光检查(胸部x光,CXR)的需要。方法:招募年龄在18岁以上、需要NGT喂养的患者。排除标准:3个月内食管胃肠手术;全部或部分胃切除者;胃和十二指肠溃疡出血;胃癌;食管静脉曲张患者;被认为是不合适的。指数测试,NGPOD,包括一个精细的,柔性的光纤传感器,通过NGT,然后连接到一个电子设备。pH≤5.5时绿灯亮,>5.5时红灯亮。参考试验是抽出胃吸液,用通用pH指示剂条进行测试,然后与彩色图表进行比较。二线检测是在重症监护室(ICU)通过CXR或主观临床评估(SCA)确定NGT位置。结果:分析的数据集包含174名受试者,他们进行了496次测试,96次首次和400次重复NGT检查。对于所有患者,NGPOD可将CXR或SCA的需求减少21.2%。在ICU中,NGPOD可减少24.5%的CXR或SCA需求。在置管后立即进行初始测试时,NGPOD可以减少61%的患者对CXR或SCA的需求。通过重复测试,NGPOD可以在16%的测试中减少进展到CXR或SCA的需要。结论:NGPOD提供的客观,是-否结果消除了pH条颜色变化的主观读数,减少了主观因素。指数测试有机会降低风险,提高安全性并减少需要x光检查的患者数量。因此,它有可能减少与NGT错位相关的任何事件。

Fibre-optic, electronic pH test device compared with current NHS guidance to confirm nasogastric tube placement.

Fibre-optic, electronic pH test device compared with current NHS guidance to confirm nasogastric tube placement.

The clinical objectives of this prospective, random, convenience series were: 1. Compare a novel fibre-optic pH test device (NGPOD) to gastric aspirate and pH testing for nasogastric tube (NGT) confirmation. 2. Determine if the new device reduces the need for chest radiography (chest X-ray, CXR).

Methods: Recruitment of patients over the age of 18, requiring NGT feeding.Exclusion criteria: oesophageal gastrointestinal surgery within 3 months; all those with partial or total gastrectomy; bleeding gastric and duodenal ulcers; gastric cancer; those with oesophageal varices; those considered to be inappropriate.The index test, NGPOD, comprises a fine, flexible fibre-optic sensor passed down the NGT, then connected to an electronic device. A green light indicates pH ≤5.5, and a red light if pH is >5.5.The reference test is withdrawal of gastric aspirate and testing with universal pH indicator strips then comparison to a colour chart. Second-line testing is establishing NGT position by CXR or subjective clinical assessment (SCA) in intensive care unit (ICU).

Results: The analysed data set contained 174 subjects who had undergone 496 tests, 96 initial and 400 repeat NGT checks.For all patients, NGPOD can reduce the need for CXR or SCA by 21.2%.In ICU, NGPOD can reduce the need for CXR or SCA by 24.5%.When performing initial tests, immediately after tube placement, NGPOD can reduce the need for CXR or SCA in 61% of patients.With repeat testing, NGPOD can reduce the need to progress to CXR or SCA in 16% of tests.

Conclusions: The objective, yes-no result delivered by NGPOD, eliminates the subjective reading of a pH strip colour change, reducing the subjective element. The index test has the opportunity to reduce risk, improve safety and decrease the numbers of patients requiring X-ray. It, therefore, has the potential to reduce never events associated with NGT misplacement.
