目的:研究床旁超声引导下鼻肠管置管术在危重症患者中的应用价值。方法:所选时间范围为2022年6月至2024年6月入ICU治疗的急危重症鼻肠管置管术患者共计60例,按照随机数字法分作研究组(床旁超声引导下鼻肠管置管术)和对照组(普通盲插法置管),评估两组一次性插管成功概率、28 d全因死亡概率、成功置管花费时间、ICU住院时间与总住院时间、营养指标。结果:研究组一次性插管成功概率29 (96.67%)、28 d全因死亡概率2 (6.67%)低(P Objective: To investigate the application value of bedside ultrasound-guided nasointestinal tube placement in critically ill patients. Methods: A total of 60 critically ill patients who underwent nasointestinal tube placement in the ICU from June 2022 to June 2024 were selected and randomly divided into a study group (bedside ultrasound-guided nasointestinal tube placement) and a control group (conventional blind insertion method). The success rate of first-attempt intubation, 28-day all-cause mortality rate, time taken for successful tube placement, ICU stay duration, total hospital stay duration, and nutritional indicators were evaluated in both groups. Results: The study group had a higher success rate of first-attempt intubation (96.67%, n=29) and a lower 28-day all-cause mortality rate (6.67%, n=2) compared to the control group (P < 0.05). The study group also had shorter durations for successful tube placement, ICU stay, and total hospital stay compared to the control group (P < 0.05). After intervention, the nutritional indicators in the study group were superior to those in the control group (P < 0.05). Conclusion: The application of bedside ultrasound-guided nasointestinal tube placement in critically ill patients can significantly improve nutritional indicators, shorten ICU stay and total hospital stay, increase the success rate of first-attempt intubation, and reduce the 28-day all-cause mortality rate. Therefore, its promotion and application are recomm
