application of enteral nutrition program in patients with intra-abdominal hypertension oriented by intra-abdominal pressure

Conditions: Intra-Abdominal Hypertension

Summary: in this study, relevant contents of the enteral nutrition nursing programs for severe patients with abdominal pressure were systematically searched, and quality evaluation was carried out based on existing evidence. based on evidence-based evidence, an enteral nutrition nursing program for patients with abdominal pressure was constructed, to improve the feed tolerance of patients with abdominal pressure, increase nutritional compliance rate, and improve patient prognosis.

background: enteral nutrition is the preferred method of artificial nutrition for critically ill patients. early enteral nutrition within 24 to 48 hours after admission can maintain intestinal mucosal barrier function, increase local blood flow, reduce bacterial migration, and reduce the incidence of intestinal infections. increased abdominal pressure is considered to be an independent risk factor for feeding intolerance in severe patients. patients with abdominal pressure are prone to complications such as diarrhea, abdominal distension, vomiting, and even aspiration, which forces the suspension or suspension of enteral nutrition and leads to insufficient nutritional intake in patients. at present, there is evidence that regulating enteral nutrition through monitoring intra-abdominal pressure can effectively reduce the incidence of feeding intolerance in patients. domestic and foreign scholars have formulated nutrition management programs for patients with intra-abdominal pressure from different aspects, such as monitoring and grading of intra-abdominal pressure, evaluation and management of tolerance, and prevention of complications. however, the standardized enteral nutrition feeding program oriented by the monitoring of intra-abdominal pressure has not yet formed a unified standard. objective: this study conducted a quality evaluation based on existing evidence, adopted evidence-based research methods to establish an enteral nutrition program for patients with abdominal hypertension oriented by abdominal pressure, and aimed to improve the feeding tolerance of patients with abdominal hypertension, improve the nutritional compliance rate and improve the prognosis of patients through the implementation of evidence-based practice programs.
