The technique of continuous pump/tube enteric feeding is being utilized with ever increasing frequency and success. Commercially available formulas are being repackaged in 1-liter plastic containers for ease in clinical use. The nutrient solution often hangs at the patient's bedside at room temperature for periods of 8 to 12 hrs and the possibility of significant and serious bacterial growth must be recognized as a potential problem. Though this has never appeared to be a clinical problem in over 15,000 pump/tube feeding days, the bacteriology has not been previously studied. This preliminary study suggests that the major source of nutrient solution contamination relates to the technique of transfer from the commercial can to the clinical liter plastic container and that "hang" times of 8 to 12 hrs at room temperature are quite reasonable if appropriate care is exercised in the transfer process.
持续泵注/管饲肠道喂养技术的应用频率和成功率越来越高。市售配方奶被重新包装在1升塑料容器中，以便于临床使用。营养液通常在室温下挂在患者床边8至12小时，必须认识到细菌大量繁殖的可能性是一个潜在问题。尽管在超过15000天的泵注/管饲喂养中从未出现过临床问题，但此前尚未对其细菌学进行研究。这项初步研究表明，营养液污染的主要来源与从商业罐装转移到临床1升塑料容器的技术有关，并且如果在转移过程中采取适当的护理措施，在室温下“悬挂”8至12小时是相当合理的。
