ICU谵妄患者病因分析以及处理

分析急诊ICU患者出现谵妄症状的原因以及处理对策.分析总结我院急诊ICU 3年间所有患者的资料,发现20.2％的患者出现谵妄症状,原因为:(1)疾病相关；(2)药物相关；(3)监护环境等多种因素作用结果.经过调整治疗方案、加强心理护理后,需要镇静药物的仅为谵妄患者的19.7％.因此寻找谵妄原因很重要,治疗重点在于去除谵妄原因以及相关促发因素.     

利奈唑胺治疗ICU革兰阳性球菌感染的疗效及安全性观察

为了评估利奈唑胺治疗ICU革兰阳性球菌感染的疗效与安全性,回顾性分析了我院中心ICU接受利奈唑胺治疗的28例革兰阳性球菌感染患者的临床资料。结果显示治疗的总有效率为75％（21／28）,耐甲氧西林金黄色葡萄球菌感染患者有效率73．33％（11／15）,表皮葡萄球菌感染患者有效率66．67％（4／6）,屎肠球菌感染患者有效率80％（4／5）,溶血葡萄球菌感染患者有效率100％（2／2）,人葡萄球菌感染患者有效率100％（2／2）。治疗过程中不良反应发生率为25％。不良反应经对症处理后好转,无需停药。故得出结论,利奈唑胺是治疗革兰阳性球菌感染有效、安全的药物,值得进一步临床验证。     

ICU患者的浅镇静：我们追求的目标？

镇静治疗是ICU综合治疗的重要组成部分。随着ICU的发展,先后颁布了3个有关ICU患者的镇静指南,镇静治疗的理念也逐渐发生改变。2013年美国重症医学会颁布的ICU成人患者疼痛、躁动、谵妄治疗指南推荐的镇静目标为浅镇静。该指南是以大量临床研究结论为基础提出的,更具有广泛代表性和推广价值。本文从浅镇静的理论基础、具体实施方案、镇静深度的监测、镇静药物的选择以及浅镇静的局限性等方面具体阐述ICU患者浅镇静策略的相关问题,以期ICU同道能更好地理解和临床实施ICU成人患者的浅镇静策略。     

ICU镇静药物的选择：苯二氮卓还是非苯二氮卓

2013年美国危重症医学会新发布的镇静、镇痛、谵妄治疗指南中指出,苯二氮卓类镇静药物的使用是ICU重症患者谵妄发生的独立危险因素,推荐ICU镇静优先采用非苯二氮卓类镇静药物以改善临床预后.的确,大量的研究表明以右美托咪定为代表的非苯二氮卓类药物相比苯二氮卓类镇静药,能明显缩短重症患者机械通气时间、ICU住院时间、减少ICU费用,并减少ICU谵妄的发生.然而事物总有两面性,ICU镇静不只是单凭药物调整便能顺理成章完成的事情.相比依据指南盲从简单的停用某种药物,建立完整的疼痛、躁动、谵妄评估系统,制定个体化镇静计划,保证机械通气有效性显得更为重要.     

中年人睡眠相关行为与高血压关系的病例对照研究

为探讨中年人睡眠相关行为与高血压发病风险之间的关系。本研究采用1：1匹配的病例对照研究法;资料收集方法采用问卷调查法;资料处理分析采用t检验及多元条件Logistic回归模型分析法。结果显示中年人病例组与对照组睡眠质量存在显著性差异（t=6．19,P〈0．05）。（1）睡眠相关行为（每日睡眠不足、夜间睡眠不足、睡眠时点延迟、睡眠质量差、入睡困难、每周入睡困难次数增加及打鼾等因素）多元条件Logistic回归模型的OR值和95％CI分别为[（OR=5．07,95％CI：3．12～8．21）;（OR=5．57,95％CI：3．43～9．04）;（OR=2．27,95％CI：1．49～3．47）;（OR=2．17,95％CI：1．60～2．94）;（OR=3．36,95％CI：1．47～7．69）;（OR=1．55,95％CI：1．08～2．24）;（OR=2．69,95％CI：1．86～3．88）]。（2）适当午睡为（OR=0．85,95％CI：0．74～0．98）。（3）早起与否（OR=1．40,95％CI：0．87～2．20）。因此（1）中年人睡眠相关行为与高血压发病密切相关,每日睡眠不足、夜间睡眠不足、睡眠时点延迟、睡眠质量差、入睡困难、每周入睡困难次数增加及打鼾等因素可能为高血压发病的危险因素;（2）中年人适当午睡可能是高血压发病的保护性因素;（3）是否早起与高血压发病关系尚不清晰。     

SLE患者焦虑抑郁影响因素调查分析

为了探讨SLE（systemic lupus erythematosus）即系统性红斑狼疮患者焦虑抑郁心理影响因素,应用Zung焦虑自评量袁（Self—rating anxiety scale,SAS）和抑郁自评量表（self—rating depression scale,SDS）,对36例系统性红斑狼疮患者进行检测,辅以自行设计因素调查表进行相关因素调查。结果显示,SDS和SAS均分为49．70±11．3和42．13±8．9,与国内常模比较,差异有统计学意义,P〈0．01。单因素分析显示：对疾病的恐惧感、对病情了解程度、治疗效果、药物副作用、家庭经济状况、家庭支持、婚姻关系、睡眠质量、担心事业受影响、躯体症状的反复出现、社交娱乐活动受限、担心医护不精心12项因素与SLE患者抑郁焦虑状态的发生显著相关,P〈0．01。证明SLE患者抑郁焦虑心理与对疾病的恐惧感、治疗效果、家庭经济状况、睡眠质量等因素相关,这为心理干预提供了依据。     

孤立性心肌桥-壁冠状动脉患者的多层螺旋CT及临床分析

试图分析孤立性心肌桥-壁冠状动脉（MB—MCA）病变患者的多层螺旋CT（MSCT）的影像学特点与临床表现之间的内在联系。回顾性收集自2003年1月至2007年3月,在我院住院并行MSCT,保存有清楚影像学资料,临床排除有其他心脏病合并症的MB—MCA患者,共53例,发现MB—MCA病变65处。平均年龄（57．3±12．6）岁,其中男性27例,LAD病变59例。MCA长度（20．8±11．2）mm,MB厚度（2．0±1．6）mm。58．5％的患者有心电图改变,大部分为女性,有胸部不适症状者占90．6％。单纯应用非二氢吡啶类钙离子拮抗剂者15例,治疗有效率达到73．3％（11例）,单纯应用β受体阻滞剂者12例,症状缓解率达到66．7％（9例）。单纯应用硝酸酯类药物者16例,仅有2倒（12．5％）缓解。MB—MCA可能导致心肌缺血和临床症状,可进行干预性治疗;对硝酸酯类药物不能缓解的胸痛患者要想到MB—MCA可能,有条件者应该进行MSCT等影像学检查,诊断明确的可以试用β受体阻滞剂及非二氧吡啶娄拮抗剂．     

ICU谵妄的预防：早期活动

ICU谵妄发生率高、识别率低,可显著延长ICU平均住院时间、增加病死率、加重转出ICU后认知功能障碍.但目前缺乏有效的谵妄预防措施.综合干预措施可降低谵妄的发生,其中早期活动是治疗的关键.ICU早期活动安全可行,可降低谵妄的发生及缩短谵妄的持续时间,改善患者预后.ICU中开展早期活动治疗是基于＆quot;ABCDE＆quot;集束化干预措施的前提下,中断镇静后尽早开始肢体功能锻炼和职业治疗,包括从先被动后主动的关节活动,到双腿下垂坐到床缘,进一步下床坐到轮椅上甚至步行活动,是早期活动的基本流程.     

不同5-HT3受体拮抗剂预防腹腔镜术后恶心呕吐的临床观察

观察使用不同5-HT3受体拮抗剂预防全麻下腹腔镜手术术后恶心呕吐的临床效果。选择160例气管内插管全身麻醉下腹腔镜手术,随机分四组,每组40例,手术结束前30min分别静脉注射昂丹司琼4mg（A组）;托烷司琼2mg（B组）;格拉司琼3mg（C组）;D组为对照组。记录术后2h、6h、12h、24h患者恶心、呕吐出现的例数。结果四组患者术后恶心呕吐的发生率是一个逐渐下降的趋势,A、B、C三组与D组相比较有显著性差异（P〈0．05）;术后2h、6h、12hB组与A组、C组相比较有显著性差异（P〈0．05）;而术后24hA、B、C三组差异无统计学意义,A、B、C三组抑制恶心呕吐的有效率分别为67．5％、87．5％和70．0％,与对照组比较差异有统计学意义（P〈0．05）,随访患者24h内无与药物相关的不良反应。结论：三种药物都能有效地预防术后恶心呕吐,但12h内托烷司琼的有效性更为明显。     

临终患者不同救治态度的转归及影响因素分析

分析ICU终末期患者不同救治方式的临床转归及其影响因素。根据患者家属救治态度分为三组,1组明确要求积极救治;2组要求维持现有治疗;3组放弃所有治疗。结果发现积极还是放弃治疗的选择与患者家属经济状况明显相关,家庭经济条件较好的患者家属倾向于选择积极治疗,经济差者倾向于选择放弃治疗。1组患者ICU住院时间长、日均费用最高,...

随着重症医学的发展,重症医学科暴露的患者安全问题已逐步引起人们关注。重症医学科患者安全问题与医务人员职业倦怠、医患关系、团队合作、科室管理等因素密切相关,提高科室高效管理、加强团队建设、提高人文素养等措施是重要有效的解决办法。     

Disturbed memory and amnesia related to intensive care

Patients, when admitted to an intensive care unit (ICU), have one thing in common: their illness is life-threatening. Patients may remain on ICU in a critical condition, needing support with their breathing, circulation, and/or kidneys for varying lengths of time, from days to weeks. During that time the patients will receive sedative and analgesic drugs to ensure compliance with artificial ventilation. Patients recovering from critical illness frequently have little or no recall of their period in ICU, or remember nightmare, hallucinations, or paranoid delusions. The nature, extent and reason for these difficulties, have been under-reported and consequently our purpose was to conduct a review of memory problems experienced by ICU patients. A systematic literature review of computer databases (Medline, PsycLit, and CINAHL) identified 25 relevant papers. In addition, other relevant articles were obtained, citation lists and associated articles retrieved. Due to lack of research on processes underlying memory problems in ICU patients all articles that introduced an insight into possible mechanisms were included in the review. There seem to be two possible processes contributing to memory problems in ICU patients. First the illness and treatment may have a general dampening effect on memory. Delirium and sleep disturbance are both common in ICU patients. Delirium can result in a profound amnesia for the period of confusion. Sleep deprivation exacerbates the confusional state. Slow wave sleep is important for the consolidation of episodic memories. Treatment administered to patients in ICU can have effects on memory. Opiates, benzodiazepines, sedative drugs such as propofol, adrenaline, and corticosteroids can all influence memory. In addition, the withdrawal of drugs, such as benzodiazepines, can cause profound withdrawal reactions, which may contribute to delirium. Second, we hypothesise that there is a process that affects memory negatively for external events but enhances memory for internal events. The physical constraints and social isolation experienced by ICU patients and the life-threatening nature of the illness may increase the experience of hypnagogic hallucinations. Attentional shift during hypnagogic images from external stimuli to internally generated images would explain why ICU patients have such poor recall of external ICU events, but can clearly remember hallucinations and nightmares. Patients describe these memories as being very vivid and this is explored in terms of flashbulb memory formation. The absence of memories for real events on ICU can result in ICU patients remembering paranoid delusions of staff trying to kill them, with little information to reject these vivid memories as unreal. This has implications for patients' future psychological health.

目前我国ICU患者入住的标准是否过于宽泛

ICU是一个由特定人员与先进医疗设备组成的独立科室或病房,是现代化医院的重要标志。ICU的建立挽救了大量危重患者的生命,降低了死亡率。目前国内ICU还处于建设、完善、发展阶段,由于发展的不平衡,缺乏统一ICU规范和收治标准,以及对ICU在认识上存在着误区,因此,造成了不同等级医院、不同层次ICU收治的不平衡。如何使ICU的建设和运作更加程序化、专业化、规范化,真正发挥ICU的作用与功能,既要加强对患者与老百姓的宣传力度,也要加强业内人员的认识,同时还应加强医疗行政管理的监察力度。     

如何降低ICU费用——规范ICU的建设和管理

ICU收费高的主要症结在于ICU的建设和管理需要规范化,包括在中国制定ICU的收治和转出指征规范,减少过度医疗和延迟医疗;积极配备ICU人力资源,提高监护质量,培训ICU专业医师上岗,掌握并运用专业知识施救,保证治疗的恰当性。允许恰当的家属陪护,对患者给予情感支持,或可降低镇静药物等的使用,缩短住院日;对于脑死亡、植物状态以及癌症晚期或其他晚期疾病的临终患者,提倡放弃治疗,避免无益救治造成卫生资源的浪费,对家属造成巨大的精神压力和经济负担。但是医生主动放弃治疗的决定尚需要政策的支持和法律的保障。     

The Association Between Delirium and Cognitive Decline: A Review of the Empirical Literature

Delirium is a common neurobehavioral syndrome that occurs across health care settings which is associated with adverse outcomes, including death. There are limited data on long-term cognitive outcomes following delirium. This report reviews the literature regarding relationships between delirium and cognitive impairment. Psych Info and Medline searches and investigation of secondary references for all English language articles on delirium and subsequent cognitive impairment were carried out. Nine papers met inclusion criteria and documented cognitive impairment in patients following delirium. Four papers reported greater cognitive impairment among patients with delirium than matched controls. Four papers reported higher incidence of dementia in patients with a history of delirium. One study found 1 of 3 survivors of critical illness with delirium developed cognitive impairment. The evidence suggests a relationship between delirium and cognitive impairment, although significant questions remain regarding the nature of this association. Additional research on delirium-related effects on long-term cognitive outcome is needed.
