Abstract

Abstract Nasogastric feeding is commonly used to deliver enteral feed in critically ill patients and several methods are used for assessing the gastric residual volume with limitations. A new approach for gastric emptying time measurement has been developed using Electric Impedance Method (EIM). The study aims to establish whether EIM is useful for measuring gastric emptying during nasogastric feeding compared with nasogastric suction. The pilot study was performed among the patients in the Intensive Care Unit (ICU), Bangladesh, from 2018 to 2019. Enteral feed was given to patients by NG tube. Gastric emptying and Gastric Residual Volume (GRV) were measured using EIM and nasogastric suction tube. Patterns of filling and emptying were almost the same in all subjects but emptying time varied between individuals that correlated well with GRV in 16 patients. Therefore, the study showed that the measurement of gastrc volume by the non-invasive and hazard-free electrical impedance method has a high specificity (90%) and efficacy of 80%. The study also revealed significant changes in gastric emptying time due to different body statuses. EIM seemed to be capable of measuring gastric emptying over time. EIM could become a standard tool for monitoring gastric emptying in patients at risk of gastroparesis.

电阻抗法评价危重病人胃排空:一项初步研究

摘要胃肠道喂养通常用于危重患者的肠内喂养，几种方法可用于评估胃残余容量，但有局限性。利用电阻抗法（EIM）开发了一种测量胃排空时间的新方法。本研究旨在确定与鼻胃抽吸相比，EIM是否有助于测量鼻胃喂养期间的胃排空。该试点研究于2018年至2019年在孟加拉国重症监护室（ICU）的患者中进行。采用NG管对患者进行肠道喂养。用EIM和鼻胃吸引管测量胃排空和胃残余容积（GRV）。所有受试者的充盈和排空模式几乎相同，但排空时间因个体而异，这与16名患者的GRV有很好的相关性。因此，研究表明，采用无创、无危险的电阻抗法测量胃窦体积具有较高的特异性（90%）和80%的有效性。研究还发现，由于不同的身体状态，胃排空时间发生了显著变化。EIM似乎能够随着时间的推移测量胃排空。EIM可以成为监测胃轻瘫患者胃排空的标准工具。
