Abstract：Objective To observe the application effects of electromagnetic navigation nasointestinal tube implantation to critically ill neurosurgical patients.Methods A total of 60 patients with severe neurosurgical conditions admitted to a Grade Ⅲ A hospital in Beijing from January 2023 to December 2023 were selected by convenience sampling method,and randomly divided into the experimental group and the control group with 30 patients in each group.The experimental group was treated with electromagnetic navigation nasointestinal tube insertion technology and the control group was treated with blind catheterization.The total success rate of catheterization,the success rate of once-only catheterization,the occurrence of catheterization-related adverse events in the two groups were compared,and the nutritional indexes(hemoglobin(Hb)and serum albumin(Alb)before intervention and 10 days after intervention were compared and analyzed.Results The total success rate of catheterization was 96.7%in experimental group and 80%in control group.The success rate of once-only catheterization was 93.33%in experimental group and 73.33%in control group.The duration of catheterization was(16.20±5.65)min for the experimental group and(34.13±13.60)min for the control group.The differences between the two groups were statistically significant(P<0.05).In terms of adverse events related to catheterization,the incidence of nasal mucosal hemorrhage in the experimental group was 1 case,cough in 1 case,whereas the incidence of nasal mucosal hemorrhage in the control group was 4 cases,cough in 5 cases,nausea and vomiting in 3 cases,and the difference was statistically significant(P=0.036),and no complications such as pneumothorax,perforation and gastrointestinal bleeding occurred in the two groups.In terms of nutritional indexes,there was no statistically significant difference in the improvement of nutritional indexes at 10 days after catheterization between the two groups,but the difference in nutritional indexes before and after catheterization in the experimental group was statistically significant(P<0.05).Conclusion The application of electromagnetic navigation nasointestinal tube insertion technology in critically ill neurosurgical patients has a higher success rate,shorter operation time,lower rate of catheter-related adverse events incidence,and can provide early nutritional support for critically ill neurosurgical patients.
