基于应激适应理论的早期心理干预预防重症患者谵妄的效果及机制研究

摘要

目的 研究在预防重症患者谵妄中开展基于应激适应理论的早期心理干预的临床效果及机制。方法随机选取我院2023年10月至2025年10月期间接收的ICU重症患者60例作为研究对象，分组采取随机数字表法，将60例患者分为观察组30例和对照组30例，对照组患者接受常规护理，观察组患者采取基于应激适应理论的早期心理干预，将两组护理结果进行对比分析。结果 观察组患者谵妄发生率低于对照组，谵妄持续和ICU住院时间均短于对照组，患者及家属对护理满意度高于对照组（P＜0.05）。结论 将基于应激适应理论的早期心理干预应用于ICU重症患者中，可进一步提高临床护理质量，减少患者谵妄发生，缩短患者的ICU住院时间。

Abstract

Objective To study the clinical effect and mechanism of early psychological intervention based on the stress adaptation theory in the prevention of delirium in critically ill patients.
Methods Sixty critically ill patients in the ICU admitted to our hospital from October 2023 to October 2025 were randomly selected as the research subjects. The 60 patients were divided into an observation group of 30 cases and a control group of 30 cases by the random number table method. The patients in the control group received routine care, while those in the observation group received early psychological intervention based on the stress adaptation theory. The nursing results of the two groups were compared and analyzed.
Results The incidence of delirium in the observation group was lower than that in the control group, and the duration of delirium and the length of stay in the ICU were both shorter than those in the control group. The satisfaction of patients and their families with the nursing care was higher than that of the control group (P < 0.05).
Conclusion   The application of early psychological intervention based on the stress adaptation theory to critically ill patients in the ICU can further improve the quality of clinical nursing, reduce the occurrence of delirium in patients, and shorten the length of ICU stay for patients.
