床旁超声引导下鼻肠管置管术在危重症患者中的应用
The Application of Nasointestinal Tube Placement Guided by Point-of-Care Ultrasonography in Critically Ill Patients

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 < 0.05)；研究组成功置管花费时间、ICU住院时间与总住院时间均低于对照组(P < 0.05)；干预后，研究组营养指标优于对照组(P < 0.05)。结论：床旁超声引导下鼻肠管置管术运用在急危重症患者中，可明显改善患者营养指标，缩短ICU住院时间与总住院时间，提升一次性插管成功概率，降低28 d全因死亡概率，建议推广与运用。
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 recommended.
