RESUMEN
Objective:To study the optimal nutritional support strategy in critical patients with acute ischemic stroke.Methods:50 critical patients with acute ischemic stroke were divided into two groups.One group were started with enteral nutrition alone within 24h after admission,while the other group received sequential parenteral and enteral nutrition.The incidence of pulmonary infection,gastric retention,upper gastrointestinal bleeding,hypoglycemia and hyperglycemia were compared between the two groups.Another endpoint was discharge from ICU at day 20,and it was compared between the two groups using Kaplan-Meier methods.Results:There was no difference between the two groups in the rate of hypoglycemia or hyperglycemia (P ＞ 0.05).The incidences of pulmonary infection,gastric retention,upper gastrointestinal bleeding and diarrhea were lower in the PN+EN group than EN group (P ＜ 0.01).The length of ICU stay was also shorter in the PN+EN group.Conclusion:The strategy of sequential parenteral and enteral nutrition decreased the complication rate related to nutrition support,such as pulmonary infection,gastric retention,upper gastrointestinal bleeding.Also,it shortened the ICU stay in critical patients with acute ischemic stroke.
