Abstract:Objective To observe the application effect of intra-abdominal pressure (IAP) monitoring in enteral nutrition of patients with severe stroke, and guide clinical enteral nutrition treatment. Methods A total of 78 patients with severe stroke who received early enteral nutrition in Neurosurgical Care Unit (NICU) of the Affiliated Hospital of Qingdao University from July 2021 to January 2022 were selected. The patients were divided into observation group (intra-abdominal pressure monitoring group) and control group (conventional gastric residue monitoring group) by random number table method, with 39 patients in each group. The patients in control group used the routine gastric residue monitoring method to pump the gastric contents back with a syringe every 4 hours. The observation group used the intra-abdominal pressure monitoring method to measure the intra-abdominal pressure of patients every 4 hours. The time when the target feeding amount of enteral nutrition reached the standard, the rate of feeding up to the standard on the 7th day, the incidence of feeding intolerance, serum nutritional indicators, acute physiology and chronic health evaluation (APACHEⅡ) and NICU hospital stay were compared between two groups. Results After intervention, the observation group was superior to the control group in terms of the time to reach the target feeding amount for enteral nutrition, the rate of reaching the target feeding rate on the 7th day, the incidence of feeding intolerance, albumin, and APACHEⅡ scores (P<0.05); There was no statistically significant difference in the length of stay in NICU (P＞0.05). ConclusionsFor patients with severe stroke who start enteral nutrition early, using intraperitoneal pressure monitoring guidance can significantly shorten the time for patients to reach the target feeding amount, improve the therapeutic effect of enteral nutrition, and improve the prognosis of patients.
