目的：探讨床边放置鼻空肠营养管在重症急性胰腺炎（SAP）病人应用中的安全性和有效性。方法：按我科执行的床边放置鼻空肠营养管操作规范，连续性地为2012年4月1日至10月1日入院的SAP病人床边放置鼻肠管，记录操作时间、营养管位置和相关并发症。结果：共有58例SAP病人床边放置鼻肠管63次，跨幽门成功率为90．5％，将鼻肠管头端送达Treitz韧带以下10cm的成功率为85．7％；平均操作时间为（24．4±7．7）vain，平均放置鼻肠管费用为（1951．2±184．7）元；无严重并发症发生。结论：床边放置鼻肠管操作简便、安全、有效、性价比高，是SAP病人建立肠内营养通道的良好选择。

Objective： To evaluate the safety, efficaciousness of bedside Naso-Jejunal feeding tube insertion in severe acute pancreatitis （SAP） Methods： The bedside Naso-Jejunal feeding tube blinding insertion of consecutive SAP patients from April 1st 2012 to October 1st 2012 were collected. We recorded time used, position of the tube＇s tip and complications associated with the bedside opera- tions. Results ： A total of 58 patients were collected in this study, and 63 insertions were preformed. Out of the 63 insertions, 57 （90.5%） tube~ tips were in postpyloric, and 54 （85.7%） in the jejunum. The average time for the placement was （24.4 ＋ 7.7） rain. The average cost was （ 1 951 ＋ 184.7） yuan. No severe complications occurred. Conclution： The bedside Naso-Jejunal feeding tube blinding insertion is safe, and effective. It is a good choice for establishing enteral nutrition channel in SAP pa- tients.
