The efficacy and safety of nasoenteral feedings via small bore, flexible tubes have been extensively studied and reported. Most of the tubes currently used have similar characteristics including a high price ($7.00-$17.30 per tube). Our study using inexpensive ($0.55 each), polyvinyl pediatric feeding tubes and reusable guide wires in 21 patients shows that a weighted tip is not necessary for the passage of tubes into the duodenum (19/27 tubes passed) and that with proper nursing care and patient cooperation, the tubes can remain in place and patent for periods up to 71 days. The cost savings using the ubiquitous pediatric feeding tube and a reusable guide wire are significant (between $6.25 and $16.55 per tube used) and make this a more cost conscious alternative.
通过细孔柔性管进行鼻肠喂养的有效性和安全性已得到广泛研究和报道。目前使用的大多数管子具有相似的特性，包括价格高昂（每根管子7.00美元至17.30美元）。我们对21例患者使用廉价的（每根0.55美元）聚乙烯儿科喂养管和可重复使用导丝的研究表明，管子进入十二指肠并不需要加重头端（27根管子中有19根成功通过），并且在适当的护理和患者配合下，管子可以留置到位并保持通畅长达71天。使用普遍存在的儿科喂养管和可重复使用导丝可显著节省成本（每根使用的管子可节省6.25美元至16.55美元），使其成为更具成本意识的选择。
