Application and success factor analysis of placing nasointestinal tube under bedside electromagnetic navigation in elderly patients
Objective:To explore the safety and effectiveness of placing nasointestinal tubes under bedside electromagnetic navigation in elderly patients,and to investigate the factors related to successful nasointestinal tube placement.Method:A retrospective analysis was conducted on the records of all elderly patients undergoing nasointestinal tube placement under bedside electromagnetic navigation at General Hospital Of Eastern Theater Command from June 1,2021 to January 31,2024.Statistical analysis was performed on the relevant indicators of the placement tube and the factors related to successful placement.Result:A total of 163 elderly patients were included,with a total success rate of 87.7%,an average placement time of(18.5±18.9)min,an average inserted nasal intestinal tube length of(104.6±9.8)cm,and a placement-related complications rate of 1.8%.The factors related to successful placement include chronic disease as the main diagnosis(P=0.0196),preoperative placement of a gastric tube(P=0.0060),and preoperative use of prokinetic drugs(P=0.0268).Conclusion:Placing nasointestinal tubes under bedside electromagnetic navigation is an efficient and safe method for placing nasointestinal tubes in elderly patients.The success rate of placement in chronic patients is higher.Preoperative placement of a gastric tube and use of prokinetic drugs may help with tube placement.
