A pilot study was conducted to describe the frequency with which spontaneous tube displacement occurred in 105 tube-fed patients followed on a prospective basis. In addition, risk factors thought to be associated with tube displacement were studied. Since only about one-third of the tubes were monitored by followup radiographs, the actual occurrence of tube displacement is unknown. On those days when tube position was documented, a comparison of risk factors for spontaneous tube displacement was made with chi-square statistics. Two risk factors, coughing and decreased level of consciousness, were found to occur with significantly greater frequency in patients with displaced weighted nasogastric tubes, while coughing, tracheal suctioning, and upper airway intubation were significant in the dislodgement of unweighted nasointestinal tubes. None of the risk factors were significant in patients with weighted nasointestinal tubes.
进行了一项前瞻性试点研究，以描述105例接受管饲患者中鼻饲管自发移位的发生频率。此外，还对被认为与鼻饲管移位相关的危险因素进行了研究。由于仅有约三分之一的鼻饲管通过后续X光片进行监测，鼻饲管移位的实际发生率尚不清楚。在记录了鼻饲管位置的日子里，采用卡方统计方法对鼻饲管自发移位的危险因素进行了比较。结果发现，在鼻饲管移位的患者中，咳嗽和意识水平下降这两个危险因素的发生频率显著更高；而在未加重的鼻肠管移位患者中，咳嗽、气管吸引和上呼吸道插管是导致鼻肠管移位的重要因素。对于加重的鼻肠管患者，所有危险因素均无显著意义。
