Abstract：Objective To investigate the effect of applying a bed head elevation angle marker on reducing aspiration and related complications in long-term bedridden patients receiving nasogastric tube feeding.Methods A prospective randomized controlled study design was adopted.One hundred and twenty long-term bedridden nasogastric tube feeding pa-tients admitted to our hospital from March to December 2024 were selected as the study subjects and randomly divided into an experimental group and a control group using a random number table,with 60 patients in each group.In the control group,nurses elevated the bed head based on visual estimation of experience,while in the experimental group,a self-made bed head elevation angle marker was used to accurately elevate the bed head to 30°～45°.The incidence of aspiration,incidence of aspiration pneumonia,incidence of silent aspiration(detected by pepsin testing),gastric residual volume(GRV)exceeding standard rate,bed head angle compliance rate,and patient comfort(using Visual Analogue Scale/VAS)were compared be-tween the two groups.Results The incidence of aspiration(3.33%vs 21.67%),incidence of aspiration pneumonia(3.33%vs 13.33%),incidence of silent aspiration(8.33%vs 23.33%),and GRV exceeding standard rate(5.00%vs 23.33%)in the ex-perimental group were significantly lower than those in the control group(all P<0.05).Meanwhile,the bed head angle com-pliance rate in the experimental group reached 100%,significantly higher than the 75%in the control group(P<0.001),and the patient comfort VAS score in the experimental group was significantly higher than that in the control group(P=0.002).Conclusion The application of the bed head elevation angle marker can effectively improve the accuracy of bed head elevation,significantly reduce the risk of aspiration and related complications in long-term bedridden nasogastric tube feeding patients,and improve patient comfort.It is a simple and effective nursing intervention tool worthy of clinical promotion.
