重症监护室患者不适体验及其与事实记忆的关系

目的探讨重症监护室（intensivecareunit，ICU）患者不适体验及其与事实记忆（factual recollection，FR）的相关性。方法对55例ICU患者及63例普通病房患者进行标准化FR问卷调查，并对结果进行分析。结果64％的ICU转出患者有ICU不适体验，其中以气管内导管、疼痛及幻觉所引起的不适较为常见；ICU患者FR评分平均为7．25分，普通病房患者FR评分平均为13．50分，二者比较差异有统计学意义（t=3．34，P〈0．01）；Logistic回归分析表明，FR评分与ICU患者不适体验，尤其是与气管内导管、疼痛及幻觉所引起的不适的发生显著相关，0R95％CI（1．2～2．1），P〈0．01。结论ICU患者的不适体验主要来自于气管内导管、疼痛和幻觉等；ICU患者相对于普通病房患者可能存在记忆减退；FR可能与ICU不适体验的发生具有相关性。

Relationship between discomfort experience and factual recollection in patients of intensive care unit

Objective To analyze the correlation of discomfort experience and factual recollection （FR） in patients of intensive care unit （ICU）. Methods Fifty-five ICU patients and 63 ward patients partieipated in the study. Standardized questionnaires were used to evaluate all patients＇ FR and the results underwent analysis. Results The prevalence of recollection of any type of discomfort in the ICU patients was 64%. The presence of an endotraeheal tube, pain and hallucinations were identified as sources of discomfort.The median score for FR in the ICU patients was 7.25. The median score for FR in the ward patients was 13.50. The difference between them was highly significant （t =3.34, P 〈 0.01 ）. Logistic analysis revealed that discomfort, especially discomfort caused by the presence of an endotracheal tube, pain and hallucinations, was positively related to FR, OR95%CI （1.2-2.1）, P 〈 0.01. Condusions The presence of an endotracheal tube, pain and hallucinations were most frequently reported as sources of discomfort in ICU patients and their memory was often impaired. FR and recollection of discomfort appear to be related significantly in ICU patients.
