Abstract:
Objective To assess the value of bedside gastrointestinal ultrasound combined with gaswater alternate injection on nasointestinal tube positioning in critically ill patients.Methods A total of 62 critically ill patients requiring post-pyloric enteral nutrition admitted to the intensive care unit in our Hospital from May 1,2017 to December 1,2017 were enrolled.Nasointestinal tubes were blindly inserted in a bedside setting.Then,we evaluated the nasointestinal tube position using both an ultrasound with gas-water alternate injection and the traditional auscultation method after gas perfusion.Abdominal X-ray imaging was also performed in all cases as the gold standard,and the sensitivities,specificities,positive predictive values,negative predictive values,and accuracies of the tested methods were obtained.Results Sixty-two patients were confirmed by X-ray,wherein 55 were successfully catheterized and 7 were ectopic.The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of ultrasound-assisted gas-water injection were 90.9％,100％,100％,58.3％,and 91.9％,respectively,which were all higher than those of traditional gas perfusion auscultation (P ＜ 0.05).Conclusion The bedside gastrointestinal ultrasound with gas-water alternate injections for nasointestinal tube positioning in critically ill patients has a certain clinical value.
