We prospectively studied survival periods after tube feeding.
Participants were 163 bedridden older patients suffering from dysphagia.
A wide range of survival periods after tube feeding were observed within half a year without tube feeding after being bedridden. After this initial period, survival periods after tube feeding were limited to approximately half a year. Survival periods after tube feeding were positively proportional to the length of time patients were free from pneumonia after tube feeding. After tube feeding, patients died from pneumonia within half a year, and the frequency of pneumonia was 3.1 ± 2.7 times (mean ± SD) before death.
Survival periods after tube feeding for less than 1 year were primarily determined by being bedridden for more than half a year without tube feeding and once pneumonia occurred; patients who were tube fed did not survive for more than half a year.
我们前瞻性研究了经鼻胃管喂养后的生存时间。
参与者为 163 例卧床不起的老年吞咽困难患者。
在卧床不起且未进行鼻饲后的半年内，观察到经鼻胃管喂养后的生存时间存在广泛的差异。在此初始阶段之后，经鼻胃管喂养后的生存时间限制在大约半年内。经鼻胃管喂养后的生存时间与患者在经鼻胃管喂养后无肺炎的时间成正比。经鼻胃管喂养后，患者在半年内死于肺炎，且在死亡前肺炎的频率为 3.1±2.7 次（平均值±标准差）。
经鼻胃管喂养后生存时间不到 1 年主要取决于卧床不起超过半年且未进行鼻饲，以及一旦发生肺炎；接受鼻饲的患者未能存活半年以上。
