摘要
目的 探讨重症监护病房（ICU）患者三种不同体位下的胃残余量（GRV）差异性。方法 纳入本院2024年8月~2024年10月ICU收治患者共150例，全部患者分别采取半卧位（床头抬高30°）、平卧位、右侧卧位（侧卧30°），采用注射抽吸法测量三种体位的GRV。同时按照不同胃管置入深度、不同鼻饲速度分为亚组，对比三种体位的GRV。结果 （1）三种体位的GRV对比，组间不具备统计学差异（P＞0.05）。（2）不同胃管置入深度下三种体位的GRV对比，组间不具备统计学差异（P＞0.05）。（3）不同鼻饲深速度下三种体位的GRV对比，组间不具备统计学差异（P＞0.05）。结论 不同体位对于ICU患者GRV不会表现出显著差异，同时不同胃管置入深度、不同鼻饲速度均不会影响三种体位的GRV。

Abstract
Objective To investigate the in gastric residual volume (GRV) in patients in the intensive care unit (ICU) under three different positions. Methods A total of 150 patients admitted the ICU of our hospital from August to October 2024 were included. All patients were placed in three different positions: semi-reclining position (with the of the bed elevated by 30°), supine position, and right lateral position (lateral position by 30°). The GRV of the three was measured using the injection suction method. At the same time, the patients were divided into subgroups according to different depths of gastric tube placement and different speeds of enteral, and the GRV of the three positions was compared. Results (1) Comparison of GRV among the three positions showed no statistically significant difference between groups (P>005). (2) Comparison of GRV among the three positions at different depths of gastric tube placement showed no statistically significant difference between groups (P>0.0). (3) Comparison of GRV among the three positions at different speeds of enteral nutrition showed no statistically significant difference between groups (P>0.05). Conclusion Different positions do not show significant differences in GRV in ICU patients, and different depths of gastric tube placement and different speeds of enteral nutrition do not affect the V of the three positions.
Key words： Gastric residual volume; Position; Intensive care unit; Enteral nutrition; Injection suction
