A descriptive study was performed to compare the incidence of pulmonary aspiration in 25 critically ill patients who had endotracheal tubes in place and were receiving enteral nutrition through a narrow-bore nasogastric tube (n = 10) or a wide-bore nasogastric tube (n = 15). Results of chi-square analysis of this comparison were not significant, p less than 0.05. Aspiration occurred in one subject. The amount and rate of tube feeding delivered was examined. The number of checks for residual feeding was found to be significantly greater in the wide-bore tube group. A comparison of the assessment of nasogastric tube placement on x-ray examination showed that tube placement was reported on x-ray results with more frequency in the wide-bore group. Questions are raised by these observations regarding the use of narrow-bore tubes in the critically ill population with endotracheal tubes in place.
进行了一项描述性研究，以比较25例患有气管内插管并通过细孔鼻胃管（n = 10）或宽孔鼻胃管（n = 15）接受肠内营养的重症患者的肺误吸发生率。该比较的卡方分析结果无统计学意义，p小于0.05。有一名受试者发生误吸。检查了管饲的量和速度。发现宽孔管组检查残留喂养物的次数明显更多。对X线检查评估鼻胃管位置的比较显示，宽孔组在X线结果报告中管位置的频率更高。这些观察结果引发了关于在患有气管内插管的重症人群中使用细孔管的问题。
