目的 探讨呼吸重症监护室(Respiratory intensive care unit,RICU)患者谵妄发生率及危险因素分析.方法 本研究对象为2019年6月～2021年12月2021年12月114例RICU患者,根据认知、心理、生理功能等评估谵妄发生情况,并根据评估情况设为谵妄组以及对照组.比较两组患者性别、年龄、疾病类型等病历资料,采用单因素以及多因素logistic回归分析调查谵妄发生的危险因素.结果 114例患者发生谵妄48例,发生率42.11％;谵妄组以及对照组在年龄、合并低氧血症、机械通气时间、RICU住院时间、使用苯二氮类药物、医疗支付方式、家庭月收入、学历差异具有统计学意义(P＜0.05);两组性别、婚姻、居住地差异无统计学意义(P＞0.05);logistic回归性分析显示,年龄＞70岁、合并低氧血症、机械通气时间＞3天、RICU住院时间＞7天、使用苯二氮类药物是RICU患者发生谵妄的危险因素.结论 RICU患者谵妄发生率较高,危险因素涉及年龄、合并低氧血症、机械通气等,应针对高危患者开展积极的预防措施以降低谵妄发生率.
Incidence and risk factors of delirium on patients in respiratory intensive care unit
Objective To investigate the incidence and risk factors of delirium in patients with respiratory inten-sive care unit(RICU).Methods A total of 114 RICU patients from June 2019 to December 2021 were the subjects of this study.The occurrence of delirium was evaluated according to cognitive,psychological and physiological functions,and the patients were divided into delirium group and control group according to the evaluation.The medical records such as gender,age,and disease type were compared between the two groups.Univariate and multivariate logistic regression analysis was used to investigate the risk factors of delirium.Results Among the 114 patients,48 cases occurred de-lirium,and the incidence rate was 42.11％.There were statistically significant differences between the delirium group and the control group in terms of age,combined hypoxemia,mechanical ventilation time,RICU hospital stay,use of benzodiazepines,medical payment methods,family monthly income,and educational background(P＜0.05).There was no significant difference in gender,marriage and residence between the two groups(P＞0.05).Logistic regression analysis showed that age＞70 years,combined with hypoxemia,mechanical ventilation time＞3 days,RICU hospital stay＞7 days,and use of benzodiazepines were risk factors for delirium in RICU patients.Conclusion The incidence of delirium in RICU patients is high,and the risk factors include age,combined with hypoxemia,mechanical ventila-tion,etc.Active preventive measures should be carried out for high-risk patients to reduce the incidence of delirium.
