Burn patients often require protein supplementation for their nutritional support. Although these are often added to a commercial formula, published standards recommend a 4-hr hang time for manipulated open-system formulas in comparison with 24 hr for unopened closed systems. We hypothesized that use of standard closed-system formulas with the addition of protein flushes via the feeding tube twice daily would reduce nursing time and increase satisfaction. A pilot study included a time study comparing the two methods and a nursing satisfaction questionnaire. Management of an open system consistent with national standards took almost twice as much nursing time daily as the closed system with supplemental protein flushes (36.6 +/- 17.1 min vs 18.6 +/- 3.6 min; P =.051). Sixteen of 17 nurses preferred the closed system with protein flush. The results of this study were used to support expansion of the protocol change throughout the hospital.
烧伤患者通常需要补充蛋白质以提供营养支持。尽管这些蛋白质通常会添加到商业配方中，但已发布的标准建议，与未开封的封闭系统中24小时的保存时间相比，开封的开放式系统配方的保存时间为4小时。我们假设，使用标准的封闭系统配方，并通过喂养管每天两次添加蛋白质冲洗液，将减少护理时间并提高满意度。一项试点研究包括一项比较这两种方法的时间研究和一份护理满意度调查问卷。按照国家标准管理开放式系统所需的每日护理时间几乎是采用补充蛋白质冲洗液的封闭系统的两倍（36.6±17.1分钟对18.6±3.6分钟；P = 0.051）。17名护士中有16名更喜欢带有蛋白质冲洗液的封闭系统。这项研究的结果被用于支持在全院范围内扩大方案变更。
