合并腹腔高压重症患者肠内营养管理研究进展

Research progress of enteral nutrition management in severe patients with abdominal hypertension

腹腔内高压会导致肠系膜动脉灌注减少,使静脉回流受阻,肠道水肿致胃肠功能减退,而肠道排空的延迟易引起肠道水肿,进一步使腹内压增高,形成恶性循环。随着人们对肠道应激反应的中心器官及肠道屏障功能重要性的深入认识,营养支持在腹腔高压重症患者的治疗中发挥着重要作用。本文通过总结对合并腹腔高压重症患者实施肠内营养管理,执行肠内营养实施的规范化流程,评估营养风险、计算目标摄入量、动态监测腹内压,从而能够保证患者在营养支持过程中的安全性和有效性,改善营养指标及预后。

Intra-abdominal hypertension can reduce the perfusion of the mesenteric artery,block venous return and reduce gastrointestinal function due to intestinal edema.And the delay of intestinal emptying can easily cause intestinal edema,which further increases intra-abdominal pressure and forms a vicious circle.Nutritional support plays an important role in treatment of severe patients with abdominal hypertension,as people have a deeper understanding of the importance of central organ of the intestinal stress response and the function of the intestinal barrier.This paper summarizes the implementation of enteral nutrition management for severe patients with abdominal hypertension,implements the standardized process of enteral nutrition implementation,evaluates nutritional risks,calculates target calorie intake and dynamically monitors intra-abdominal pressure,so as to ensure safety and effectiveness of patients in the process of nutritional support and to improve nutritional indexes and prognosis.
