Abstract:
Malnutrition in adult intensive care unit patients is associated with poor clinical outcomes. Providing adequate nutritional support to the critically ill adult should be an important goal for the intensivist. This narrative review aims to delineate the role of parenteral nutrition (PN) in meeting nutritional goals. We examined the data regarding the safety and efficacy of PN compared to enteral nutrition. In addition, we describe practical considerations for the use of PN in the ICU including patient nutritional risk stratification, nutrient composition selection for PN, route of PN administration, and biochemical monitoring.
摘要:
成人重症监护病房患者的营养不良与不良临床结局相关。为危重患者提供足够的营养支持应该是重症医师的重要目标。这篇叙述性综述旨在描述肠外营养(PN)在满足营养目标中的作用。我们检查了有关PN与肠内营养相比的安全性和有效性的数据。此外,我们描述了在ICU中使用PN的实际考虑因素,包括患者营养风险分层,PN的营养成分选择,PN管理途径,和生化监测。
