Intrapulmonary placement of small-bore nasogastric feeding tubes caused pneumothoraces in four patients. Review of the literature discloses another 106 cases of the same complication. Risk factors for intrapulmonary complications include endotracheal intubation or tracheostomy (60% of reported cases [95% confidence interval, 44% to 80%]), and altered mental status (36% of reported cases [95% confidence interval, 24% to 53%]). We propose a simple, two-step method of feeding tube insertion designed to prevent such complications in high-risk patients.
细孔鼻胃饲管在肺内放置导致4例患者发生气胸。文献回顾发现另有106例相同并发症的病例。肺内并发症的危险因素包括气管插管或气管切开（报告病例的60%[95%置信区间，44%至80%]）以及精神状态改变（报告病例的36%[95%置信区间，24%至53%]）。我们提出一种简单的两步饲管插入方法，旨在预防高危患者出现此类并发症。
